How to reference a value in an input field?

I know there is an htmldb_application utility which will let you reference input values via an array. However if I have a simple HTML form with input variables named A and B, is there some utility which will let me reference that value using the name? Is there a function which will let me reference these same values by ID?

Hi,
First of all u have to declare one variable in the prog. with the name of the i/o box u have given in the screen.
Now in the PBO of the screen call one module.
and in that module write the code like,
if your i/p field name is INPUT_F then
MODULE assign OUTPUT.
INPUT_F = 'XYZ'.
ENDMODULE.
Here u can assign the value by fatching through the DB also.
I think this will help u.
thanks

How to get the values from the input field of a table

Hello Friends
I am having table having one column as InputField and rest are the textview fields
I input the data and click the button that will add them to a node.
But what is happening is it is adding the current value to all the fields replacing other filelds.
Like suppose I am having 3 rows
In column I input 10
In column 2 input 20
In column 3 input 30
Now it is setting the value 30 to all the 3 fields.
Can any one tell me the code to set 10, 20 and 30 as different value in a node as entered by me.
Thanks

How to restrict the user to enter only numeric values in a input field

How to restrict the user to enter only numeric values in a input field.
For example,
i have an input field in that i would like to enter
only numeric values. no special characters,alphabets .
reply ASAP

Hi Venuthurupalli,
As valery has said once you select the value to be of type integer,once you perform an action it will be validated and error message that non numeric characters are there will be shown. If you want to set additional constraints like max value, min value etc you can use simple types for it.
On the project structure on left hand side under local dictionary ->datatypes->simple types create a simple type of type integer
The attribute which you are binding to value property ;make its type as simple type which you made
Hope this helps you

How to reference the value of a af:inputText at View level in a java clas

How to reference the value of a <af:inputText> at View level in a java class at Model level? Thanks!

Create AppModuleImpl class and create ther for example setMyParam procedure.
(You can use AppModule. There simple interface to do this classes
In JDev 11:
1. Go to AppModule and in Java bookmark generate application module class.(AppModuleImpl.java)
2. Put "private String myParam;" and method to access myParam "public void setMyParam(String myParam)".
3. Again in the AppModule in the Java bookmark add method to client interface.
AppModuleImpl.java
public class AppModuleImpl extends ApplicationModuleImpl implements AppModule {
* This is the default constructor (do not remove).
private String myParam;
public AppModuleImpl() {
//this.
public void prepareSession(Session session)
super.prepareSession(session);
myParam = myParam + myParam;
public void setMyParam(String myParam) {
this.myParam = myParam;
prepareSession(getSession());
AppModule.java
public interface AppModule extends ApplicationModule {
void setMyParam(String myParam);
AppModuleClient.java
public class AppModuleClient extends ApplicationModuleImpl implements AppModule {
* This is the default constructor (do not remove).
public AppModuleClient() {
public void setMyParam(String myParam) {
Object _ret =
this.riInvokeExportedMethod(this,"setMyParam",new String [] {"java.lang.String"},new Object[] {myParam});
return;
And you can use method setMyParam as you wish :))) You can find it in AppModuleDataControl..

How to save changed data from a input field to the source structure

Hi,
I have a small problem with the onChange event with HTML input fields.
When changing a value of a input field or by creating a new value for a field the OnChange event is called by moving away the mouse pointer....
get_form_field( 'field_name' ).
But is it possible to write back the new value in the source field ls_screenstructure_field1 without using the OnInputProcessing?
I ask because my application´s structures have a lot of fields that should be filled and changed by input fields.
It´s not comfortable to request every new value with .. = request->get_form_field(... .
Thanks for helping.
Cheers,
André

you wanted a onchange for a htmlb:inputfield which would also trigger server event. try the following code.
<htmlb:inputField id            = "test"
                            alignment     = "LEFT"
                            size          = "6"
                            required      = "TRUE"
                            doValidate    = "TRUE"
                            type          = "INTEGER"
                             />
<bsp:htmlbEvent id="myid" onClick="myonclick" name="ValueChanged" />
<script for="test" event=onchange type="text/javascript">
alert(this.value);
ValueChanged();
</SCRIPT>
if the value in the inputfield is changed it would trigger a alert at the client side and also trigger a server event. now you can caputre the value in oninputprocessing.
Hope this helps.
do let us know if you need help in how to capture this value in oninputprocessing.

Mixing Html/JSP - Is it possible to retain value in "file" input field?

I have a jsp page with the following snippet:
<% String text1 = (String)session.getAttribute("text1");
if(text1 == null) {
text1 = " "; }
//get more attributes here
%>
<form name="file" action="checkFields_images.jsp" method="post" enctype="multipart/form-data">
<input type="text" size="15" name="text1" value="<% =text1 %>"><br>
<input type="file" name="image1" />
<br>
<input type="text" size="15" name="text2">
<br>
<input type="submit" name="submit" value="submit">
</form>
...upon submission, it will go to a jsp that will check the fields for blanks or errors. If there are errors, the page will forward the user BACK to the original page, and each field that had an entry will be displayed with what the user had entered.
The way my code operates is when the user hits the submit button, the jsp page that checks the fields is also setting the values submitted in session attributes. Those of you familiar with JSP code will know what I mean.
That way when the page is redisplayed the "value" attributes of each <input> field will be set to what the user entered by way of such:
<input type="text" name="text1" value="<%=text1%>">
where <%=text1%> is a java variable set to the session attribute value for this <input> field.
Now I know that the <input type="file> field has a value attribute, but I don't believe it is something that can be set. So how do I workaround this? I just want the field to display the file name the user had selected. I've worked with mixing JavaScript and Java code, but there are certain things you can and can't do, and I'm coming up with any "can do's" for this one.
Any suggestions are appreciated
Thank You,
Love2Java

You are absolutely correct.
For security reasons, you can't specify a value for the input type="file".
Here is one suggestion, of how I would see it work in a perfect world.
- The file is uploaded and retained on the server
- You send back a page without an input type="file"
- The user fixes whatever fields they got wrong and submits again
- The server picks up the correct fields, along with the file sent with the "bad" request, and then continues as normal.
In this way, you only have to upload the file once.
Instead of regenerating the <input type="file">, it would generate something like "File already uploaded. Correct other fields"
pros:
- Don't have to worry about repopulating the input type="file"
- user only uploads the file once
cons:
- if the user wants to change the file? Maybe another link?
- must retain file on server somewhere, and find it later.
I didn't say it was easy, but it seems the most sensible approach to me.

Get Value From an input field

Hi All,
I am a newbie to ABAP Webdynpro.I would liketo know how should I get the value from an input field at runtime?
Thanks,Mukta

By reading the context attribute which bound to inputfield, you can get the value.
Say you have a node called 'MAIN_NODE' and has the attribute 'INPUT_VALUE', which is bound to the Inputfield.
DATA LO_ND_MAIN_NODE TYPE REF TO IF_WD_CONTEXT_NODE.
DATA LO_EL_MAIN_NODE TYPE REF TO IF_WD_CONTEXT_ELEMENT.
DATA LS_MAIN_NODE TYPE WD_THIS->ELEMENT_MAIN_NODE.
DATA LV_INP_VALUE LIKE LS_MAIN_NODE-INP_VALUE.
* navigate from <CONTEXT> to <MAIN_NODE> via lead selection
LO_ND_MAIN_NODE = WD_CONTEXT->GET_CHILD_NODE( NAME = 'MAIN_NODE' ).
* get element via lead selection
LO_EL_MAIN_NODE = LO_ND_MAIN_NODE->GET_ELEMENT( ).
* get single attribute
LO_EL_MAIN_NODE->GET_ATTRIBUTE(
    EXPORTING
      NAME = `INPUT_VALUE`
    IMPORTING
      VALUE = LV_INP_VALUE ). "LV_INP_VALUE will have the value of inputfield

How auto turn lowercase to uppercase in input-field?

Hi All,
How auto turn lowercase to uppercase in input-field?
Thanks

The way I implemented it was using a javascript function to change the case by calling the javascript function from the textfield tag with onblur event. Here is the javascript code and how it was called:
enter the following code within your with the head tag
<script>
function case_checker(){
var st = document.getElementById("form1:[Enter the textfield ID here]").value;
document.getElementById("form1:[Enter the textfield ID here]").").value = st.toUpperCase();
</script>
call the code from the textfield tag has follow:
<ui:textField binding="text" id="[Textfielf ID]" onBlur="case_checker(')" style="border-style: inset; border-color: #000000; left: 216px; top: 144px; position: absolute; width: 144px"/>

How to get the vlaue from an input field without hitting the enter button ?

Hello All,
Is there some way to read the values of an input field that was filled in by an user eg ..
String userEntry = wdContect.<UIElement>.value;
So far, I am only able to achieve this using the onEnter property whoch really is not very user friendly since I can only read in the values only if the user hits enter.
Any help will be appreciated. Thank you.

1. Create a value attribute (MyText) in the controller context
2. Create a value attribute (MyText) in the view context
3. Map view context attribute to controller context attribute
4. Create InputField in the view and map the "value" attribute to the MyText view context attribute
5. Create Action on view (Send)
6. Create Send button and specify Send action as onAction attribute
7. Create executeSend() method on controller
8. onActionSend() implementation:
public void onActionSend(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )
    //@@begin onActionSend(ServerEvent)
   wdThis.wdGet<controllername>Controller().executeSend();
    //@@end
9. executeSend() implementation:
public void executeSend( )
    //@@begin executeSend()
               // Get MyText
               String MyText = wdContext.currentContextElement().getMyText();
