Java script with struts html tag

the code show above is the main problem in the body of the function check() i just want to have a logic if the USERNAME is empty then it should alert("empty") if the name contains any spaces then it should alert("spaces are there")
can u help this out
<head>
<script language="text/javascript">
function check()
</script>
</head>
<body>
<html:form action="somename" ondbclick="check()">
USERNAME:<html:text property="username"/>
<html:submit/>
</html:form>
</body>

<html:form action="somename" ondbclick="check()">why do you plan to check it on double clicking the html form? what if the user doesn't do a double click?!
Maybe you could check it on the "onblur " event for the textbox. ->
<html:text property="username" onblur="javascript:check();"/>If you are unsure about how to work on the javascript function (because I didnt exactly understand your query :) ) then just to get you started...
function check()
         if(document.forms["0"].username.value == "")
             alert("Empty textbox!");
         //put code for checking spaces
}but do a little googling for the rest..
And if I have entirely misread your query, then please clarify...

Wls 8.1 sp2: weblogic.jspc complains about struts-html tags

          Hi,
          I am trying to compile jsps with weblogic.jspc, which use struts' html tags. However,
          the compilation fails with the following message:
          [java] Translation of /views/viewPageBody.jsp failed: (line 3): Error in using
          tag library uri='/tags/struts-html' prefix='html': The Tag class 'org.apache.struts.taglib.html.BaseTag'
          has no setter method corresponding to TLD declared attribute 'server', (JSP 1.1
          spec, 5.4.1)
          I opened the BaseTag class from the struts jar and found the setter exists for
          the attribute 'server' of html tld. So does the property 'server'. The property
          'server' is a string and the parameter in the setter is a string. I read about
          the jspc errors in wls 8.1 about the setter parameter being of different type
          than the property. However, that is not the case here. I tried using both Sun's
          and BEA's jdk. None of them help. Btw, there is another attribute mentioned in
          the html tld, which is 'target'. The compiler doesn't complain yet about this.:(
          Also, I happened to compile other apps which have struts logic tags.
          My environment:
          OS: Win2k sp3
          WLS: 8.1 sp2
          JDK: Sun's 1.4.2 sp4 / Bea's 1.4.1 sp5 (tried both)
          Ant: 1.5.3 (I had an issue earlier with ant until I found that Bea officially
          without any mention supports only ant 1.5.3.)
          I would appreciate any help in this regard.
          Thanks,
          Abbas


          What version of Struts are you trying to use?
          Are you certain you're not encountering a different instance of that class in
          an unexpected location in your classpath?

Java Script With XE

hi Expert,
Can You Tell Me how to use Java Script With XE.
Thanks
Manoj

Manoj.
By the term "Use JavaScript", do you mean how to include JavaScript functions on your page(s) or are you looking for help in what JavaScript can be used for and how to add onclick, onchange events to form elements?
If it is the former, there are several ways to include JavaScript onto your pages:
1. Edit your page in the APEX Builder and place the normal syntax into the HTML Header Section i.e
<script language="JavaScript">
function hellWorld()
alert ("Hello World");
</script>2. Check out this article on how to link in File System based Javascript files: http://djmein.blogspot.com/2007/01/reference-javascript-from-file-system.html
I hope that gets you started.
Let me know if you need any more help.

Including java script in struts

Hii All,
I wanted to use some java script function on onclick of button. like on click on calendar image i should invoke the cal control writtern in java script.
Its a pure struts application. can any1 tell me how to include java script in struts ?

it depends on the javascript file you are using as to how you are going to have to do it.. but I would imaging you will have to include the js file like this.
<script type="text/javascript"
src="<c:out value='${pageContext.request.contextPath}'/>/scripts/newCalendar/calendar.js"></script>then on how to call the javascript from the onclick it will completely depend on the actual calendar script.

Coverting java script site to html in dreamweaver

I designed a site by keeping java script (instead of html) as default in the opening page of dreamweaver cs3. How do I convert to html without redoing the same?
sasi

If you're asking how to convert your JS page to HTML or XHTML document type, go to Modify > Page Properties > Title/Encoding and select the appropriate document type.

Need help with Java script calling an html page

Hello -
I have a bunch of web pages, that call a java script called "header.js". The "header.js" puts a header on the top of each web page. In the Java script, I have a gif (picture) that displays a logo and if you click on it, it will send to you a different website.
I'd like to replace this gif with an actual web page. So, the "header" would actually be a web page and not some gif.
Below is a snippet of the code and I'd like to replace the highlighted section with a web page called "header.html". I don't even know if this is possible.
Can anyone tell me what I need to do? I know pretty much nothing about Javascripting so please be as detailed as you can. Thanks!

//document.write('');
document.write('                                                             </ul>');
document.write('                                            </div>');

document.write('                            <div id="right" class="float_left">');
document.write('                                            <div id="controls">');

Well, the problem with this is that I'm not an expert on SSI and I really know nothing about javascripting...so I'm afraid of breaking the whole web site and also having to modify all the web pages that call this header.
I'll have to read up on server side include...cause I don't know much about it.
If I could do what I want with this "header.js", it would be a lot easier.

Action listener for struts html tag

hi i am doing a project using sturts. I have used struts HTML Select tag with a collection of values in select box. now i want to write an actionlistner for that select...ie if i select any value from the select list it should do some action like take me to different page...can anyone tell me how can i do that...
Thanks

Soultech, I think you're being a bit harsh. Struts is a valid topic on this forum as it is a java framework related to JSP.
However having said that, the question does show a basic misunderstanding of JSP technology.
JSP = Java SERVER Pages. Java code only runs on the server.
All that gets sent to the client (browser) is an HTML file.
You can not write java action listeners to run and respond to events on the client.
For any client side interaction you will have to use javascript (which is NOT java) - probably an onclick/onchange event - the same as any other web page.
However you can only run javascript code from such events.
To run java again you have to submit a request to a server - normally done by submitting a form.

I don't know about that, but I am using MyFaces and tomahawk with WLS8.1 sp5 jdk1.4.2_05 and it works fine.
I do remember getting such an error when I moved from Sun RI to MyFaces and all I can recall is that it was a commons library mismatch problem or some classpath problem...

Can I use java script with iWeb?

I am quite pleased with iWeb for my web requirements, commercial and private, but I need to insert java script and don't know how or if iWeb accepts it.

All custom code, including JavaScript, is pasted in the HTML Snippet.
Read this : Using the HTML Snippet
Everything you paste there, is your responsibility.
iWeb happily publishes your code, whether it works or not. If not, mend it.
See examples here :
     http://www.wyodor.net/_Demo/Fancy/Dynamic_Text.html
     http://www.wyodor.net/_Demo/html5/BlowUp.html
     http://www.wyodor.net/mfi/Maaskant/How_To.html
     http://www.wyodor.net/mfi/cultureclub/Movies.html
     http://www.wyodor.net/mfi/roodhout/How_To_Do.html
You may have to learn HTML, CSS, JavaScript, AJAX, DOM and how iWeb creates its pages. Especially that.

Java scripting with textarea?

Hello,
I am trying to read values passed by a servlet from an html form using java scripting. Here is the code:
document.MainForm.textareaInfo.value = "<%= (String)session.getAttribute("textareaInfo") %>"
This code works if the info entered in the textareadInfo field has one line with no carriage return.
How can assign value to textareaInfo field contains multi-line string with carriage return?
Thanks in advance.

Hi,
replace all "\r\n" (carriage return) in the string with "\\r\\n", so that it appears as "\r\n" in javascript.
In jdk 1.4, you can use((String)session.getAttribute("textareaInfo")).replaceAll ("\r\n", "\\\\r\\\\n")

Java script with java

sir i have seen that java 1.6 mustang version is supporrting java script
if it is so please any one can help me on how to make my JEditorPane
to support java script
not only to jEditorPane but to any other swings component
i tried in all ways please can any one give me this help

Hello Farhan,
The OP stated that there is no condition on the process. In this case, I believe only 'SUBMIT' will cause the process to be fired.
"you can put anything in the string of the doSubmit."Well, you can do that, but it will have an effect only if you are using the REQUEST variable to condition a process. Otherwise, nothing will happen, and you want even receive an error message, because no error actually exist (as I believe happened with the OP case).
Regards,
Arie.
