Pressing enter to perform a button's action

hi,
I would like to perform an action when I press a button and when I press enter (this button selected)
I have no idea how to do this.
thank you.

I think maybe on some L&F's, it might be, but not all. Space is used for most, not enter. Your other post, since you cross-posted does have an answer, I'm sure you know already.... But don't cross-post.

Pressing ENTER to perform search

Hi everyone,
Recently I have been messing about with JavaScript to make pressing the ENTER key work in my UIX pages. Maybe my solution also works in ADF Faces. Please have a look at

Welcome to Apple Discussions
Make sure you have the latest firmware installed for your wireless router.
Refine your Network settings using the following:
Go to the System Preferences>Network panel
- Location - set up a personal location by clicking on the drop down menu and selecting "add a location". Use a name familiar to you. Once established, select "apply".
- Next, click on the "Show" drop down menu and select Network Port Configurations. Only Airport ought to be checked. Move it to the top of the list (you can drag it). Select "apply".
- Back to the "Show" menu, depending on your connection select "Airport". Click on the TCP panel. There, enter 208.67.222.222 and 208.67.220.220 (separate lines) in the DNS servers box and select "apply".
Creating a personal location, plus adding the DNS codes seems to speed things up. Otherwise, the "automatic" function has a tendency to "search" for available locations.
In the Finder, go to your Utilities folder and select "Terminal". Once the screen is open enter lookupd -flushcache and press return. This clears out the DNS cache. Once done, quit Terminal.
As far as "speeding up Safari", "empty the cache" (ought to do it daily) in the Safari Menu. There are other steps, such as deleting the site icon folder, however, before you go down that route, try the above and see if Safari responds more consistently.

Invoking a command link's action from a javascript, on pressing enter key

i have the foll java script function. on pressing enter within an input field i want a certain commandlink's action to be automatically performed:
function checkKeycode() {
     alert("entered");
          var keycode;
          if (window.event) keycode = window.event.keyCode;
          //else if (e) keycode = e.which;
          if(keycode==13){
               alert("keycode: " + keycode);
               var x=document.getElementById("form10:link1");
               alert("about to click");
               x.click();
               //document.forms[0].link1.click();
               //if(validate('form1:_system_username,form1:_system_password','form1:_id0,form1:_id1','2'))
                    //alert("about to submit page");
                    //submitPage();
     }This fn is being called from the input text as follows:
<h:inputText styleClass="inputText" id="text1" size="32" onkeypress="checkKeycode();"></h:inputText>And the code containing the command link who's action i want to be called is:
<h:commandLink styleClass="commandLink" id="link1"
                         action="#{pc_Test.doLink1Action1}">
                         <hx:graphicImageEx border="0" styleClass="graphicImageEx"

                    </h:commandLink>
The javascript is being entered as i get an alert saying that enter key was pressed. However it is not performing the action requried, saying that "null is null or not an object"
could sumone please help????

Hi
From your javascript , it is known that this is only work in IE,
And indeed it works fine, mybe there is another button which the default in your jsp
Change your code like this:
onkeypress="return checkKeycode();"
and at end of your javascript return false when you call x.click

How to set default button when press "Enter"

Hi,
I have a form and it has only one button (Submit). When I press "Enter", it can submit the form and do the action. However, when I add another button (Normal button, not submit), it cannot perform submit action directly when I press "Enter".
If we press "Enter" and the form can submit automatically, it is more user-friendly than without this feature. Therefore, may I know the method of set the default button when users press "Enter"?

At first I thought the order of the form controls might matter. When I run this code:
<cfdump var="#GetTickCount()#">
<form action="TestCfgrid.cfm" method="post">
<input name="x" type="text" />
<input type="button" value="x" />
<input type="submit" />
</form>
While I am in the text box, if I press the enter key the form submits. I originally tried it with the submit and button inputs in the opposite order.
Note that the enter button will not submit the form if you are in a select control (aka dropdown) or a textarea or if your focus is not on a form element. That's the default behaviour. If you want to override that, you'll have to write some javascript.

once you click a button, say, "Draw Rectangle", it should draw a rectangleYes, but you need to repaint() the component (in your case panel) to see the change.
The error is: The method paintComponent(Grpahics) is undefined for the type ObjectThe compiler never lies. As far as your code goes, you have added a method paintComponent(...) to a class that implicitly extends Object. Perhaps you wanted to create an anonymous subclass of JPanel.JPanel panel = new JPanel() {
public void paintComponent(Graphics g) {
super.paintComponent(g);
myPaint(g);
};Note the changes in brace and semicolon placement.
Also:
1. You're setting a FlowLayout to a JPanel, which is anyhow the default layout manager. And when using a layout manager, setSize calls are redundant and effectively ignored.
2. For a JFrame to be centered on the screen, setLocationRelativeTo(null) after setting the size, not before.
3. To void visual artifacts, setVisible(true) after all other properties are set.
It looks to me like you've been throwing together bits of code from here and there without adequate understanding. I recommend you go through the Swing tutorials linked from the topic listing page for this forum.

Pressing Enter Button Gives a Blank Page while Cursor is in Text Field

Hi,
I have a problem on my jsp page that there is a text filed (input type="text") and a button (input type="button") to submit the page.
When page loads the cursor blinks in the text field, and at the same moment if i hit the enter button of my keyboard it gives a blank page.
Here the button on page does not clicked by this enter button, no script calls neither the page submitted to the given url.
Kindly suggest what is going wrong.
Thanks in Advance
Rajiv K.

I'd come across this issue a while back: [http://tipsandtricks.nogoodatcoding.com/2007/07/html-single-text-field-submit-caveat.html]; when there is only a single text field in a form, then pressing enter causes a submit with the text-field as the initiator. The submit button isn't invoked. This means any onsubmit actions will not be called. A simple way out is to put in a dummy text field in the form and set it's display to none (using CSS/styling)

Can mouse action replace the function of pressing ENTER?

hi there,
I would like to use the mouse click on the textfield to substitute the pressing <ENTER> action on the textfield, since i want the user to use mouse only but i don't have place to put button already. Is it possible to do so?
thanks

You can do it, but it wouldn't make for a very conventional user interface. Just add a mouse listener to the text field and respond to click events the same way you'd respond to the enter key being pressed.
myTextField.addMouseListener(new MouseAdapter()
public void mouseClicked(MouseEvent e)
// Now do whatever you'd do if enter was pressed
});However, this is poor GUI design.

Why does firefox 16.0.1 not allow me to click on buttons in the top 40mm below the banners, though i can get to them by tabbing to a buttons then press "Enter"?

It doesn't matter what web-page I'm on, the top 40mm or so of the screen is a dead area for clicking on buttons or links. e.g. in Google I can click on a link lower down the page and get transferred to the new article - but if I were to move the item up nearer the top of the page the link would no longer operate.
I can move to a link by repeated operation of the "Tab" key until the link or button is indicated, and then press "Enter" to use the link, but this is potentially very time-consuming if there are a lot of links on the page.
I'm using a Toshiba Satellite L750 loaded with Windows 7, and Firefox 16.0.

Problems with buttons and links at the top of the page not working can be caused by an extension like the Yahoo! Toolbar or a Babylon extension that extents too much downwards and covers the top part of the browser window and thus makes links and buttons in that part of the screen not clickable.
*https://support.mozilla.org/kb/Troubleshooting+extensions+and+themes
Start Firefox in <u>[[Safe Mode|Safe Mode]]</u> to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).
*Do not click the Reset button on the Safe mode start window or otherwise make changes.

I want to execute selection screen by pressing enter button

Hi,
I have a requirement like after giveing values in selection screen I want to execute it by pressing enter button not by pressing execute button.
Please give some sample code if u have any solution.
Thanks & Regards
Venkatrami Reddy B

Hi,
You can achive this.
You just need to do all your coding under even AT SELECTION-SCREEN OUTPUT.
But you have to put a check also say counter.
Define a variable of type integer and then put the check on the mail block of code (whole program eccept selection screen) as mentioned below.
IF lv_count > 1.
program lines..
ENDIF.
lv_count = lv_count + 1.

Can I execute a Button when pressing "Enter" in an InputField?

Hi All,
I have an InputField and next to the InputField, there is a Button.
Ii would like to have my application executing the Button when the User presses the "Enter/ Return" Button on his keyboard.
Is that possible? If yes, how??
Thanks, Johannes

Hi,
You can try using OnEnter property of the Input field for your requirement. Assign a method to the onEnter property of the input field and now when the user fills data in the field and press enter the method assigned will be executed.
Thanks,
Abhishek

Pressing enter activating other buttons in VI

Hi All,
I have an app built based on the User Event Handler template. In it I
have a graph and several buttons (so far). The odd behavior occurs
when I edit an axis range on the graph during runtime. When I type in
a new max val for an axis and press enter, it not only accepts the new
axis max val but activates one of the buttons. Any idea why this may
be occurring?
Thanks for any info,
Gc.

Good catch! The button did have 'enter' assigned to it under
Advanced/Key Navigation.
Muchos gracias!

Pressing enter instead of clicking on a button

Hey all, this is rather simple but the search term 'enter' is very common so i'm having a hard time searching for my solution!
I'm basically writing a search program that finds customers, at the moment I have a screen where the user types in a name then clicks on a button I have which executes the search.
I'd like to be able to have it search by pressing enter as well as being able to click on the button.
I tried debugging to see what the sy-ucomm was when I pressed enter but apparently that doesn't change.
Can anyone direct me to what I should be researching to implement this?
Just a few basics to get me on my way would be great,
Thanks

Hi Mate
In your PAI okcode module you can include '/00' or 'ENTE' to capture the enter keypress.
This will solve your problem.

Question about submitting a button upon pressing "Enter"

HI everyone, I am using 11.1.2.1.0.
I have a Panel Form Layout with 2 buttons (let's say, bt1 and bt2). I would want to auto trigger bt2 when user press "Enter".
Is using javascript the only to implement this ? If it is, how(where) shall I place the javascript code if I want to achieve proper placement of codes.
Thank you.

i have a idea , without using javascript
let i consider you had jspx page in that you had af:command button/command toolbar button
choose that button go to the propeties pallete in that, you can found access key property give value say as E
run your page in mozila ffx > 3.0 press alt + ctrl + e it will trigger what you what?
based on browser key will differ.
but somtimes my idea will not match/suit with your requirement so
i have another answer drag and drop the af:resource from the component pallete under jspx root
<af:resource scripttype = "javascript">
//here js code
<af:resource>
<af:commandbutton>
use some listener to invoke your javascript say as clientlistener / serverlistners
<af:commandbutton>

Trigg the 'Query' button when pressing 'Enter' on the keyboard

I have a form with 2 buttons, 'query' and 'reset'.
I would like that the 'query' button is triggerd (pressed) when the user presses 'Enter' on the keyboard. In regular html I think this is accomplished if the button is a 'submit' rather than a 'button' type, but I haven`t found a way to edit the
type of button in Portal.
Users belive it`s very annoying to have to move the mouse over the 'query' button to execute the query, and would rather like to just press 'Enter'.
I`ve tried to use a javascript (onKeyPress), but if you make a javascript in Portal, you`re not allowed to add this to your button, only as an 'form-' or 'field validation' in a textbox.
Is there anyone who knows a way to get this functionality?
Regards,
Orjan
