Accessing the value of an Input Text?

[camilo]

I'm building a webpage and using &lt;input text&gt; and &lt;select&gt; to show some data. I'm also using cold fusion but have a problem I wan't to pass the data from the text field or the list box to a CF variable in the same webpage is there anyway just to access the value and what is the instruction to do that. I'm not using forms, will I need to???<br>Example of my problem below:<br><br>&lt;!-- samefile.html --&gt;<br>&lt;cf set cad=&quot;&quot;&gt;<br>&lt;input type=&quot;text&quot; name=&quot;Data&quot; size=&quot;10&quot; maxlength=&quot;10&quot; message=&quot;Data&quot;&gt;<br><br>How do I pass the value from input to cad(e.g cad=input.text) <br>

You will definitely need to use a form, since Netscape won't show controls without a form.<br><br>This seemed to work for me in IE5, I hope it would work for you:<br><br>1) Put a [dummy] form round your controls:<br><br>&lt;FORM NAME=&quot;DummyForm&quot; METHOD=&quot;POST&quot; ACTION=&quot;dummy.htm&quot;&gt;<br>...<br>&lt;/FORM&gt;<br><br>Don't worry about the action, the form never gets submitted.<br><br>2) To access the text box's value from within the same page, without submitting:<br><br>document.forms[&quot;DummyForm&quot;].Data.value<br><br>where the name in the forms[] array matches your form's given name and Data is the name of your text box as you named it...<br><br>(This was JavaScript, in case you didn't realise - don't use VBScript, Netscape ignores it).<br><br>

um, JTeagle is right, you need a form to access the current information in the textbox. Also, the format for accessing the current information in a textbox is: (using the form example from above) document.DummyForm.Data.<b>value</b>, not document.DummyForm.Data.<b>text</b><br><br>you could also use:<br><br>document.forms[&quot;DummyForm&quot;].Data.value, but document.DummyForm.Data.value is shorter. <p>theEclipse<br><a href=mailto:eclipse_web@hotmail.com>eclipse_web@hotmail.com</a><br><a href=robacarp.webjump.com>robacarp.webjump.com</a><br>**-Trying to build a documentation of a Javascript DOM, crossbrowser, of course.

Can you be sure Netscape supports the control name as a direct object, rather than an entry into an array of objects?

That method has always worked for me, and thats the way that I learned it at <A HREF="
