Well, I think first you'd need to change the name of the <html:text> element
to something other than artist to avoid javascript confusion. The value for
artist will be posted to the server by the <html:select> object.
(watch for line breaks)
<script language="JavaScript">
<!--
function setArtist(control){
document.forms[0].artistReadout.value=control.options[control.selectedIndex]
.value;
}
//-->
</script>
PullDown and text field:
<html:text property="artistReadout" size="40"/>
<html:select property="artist" onchange="setArtist(this);">
<html:options collection="artist" property="value" labelProperty="label"/>
</html:select>
The javascript event you want to use in onchange, not onclick.
The syntax to pull the value out of a select list is a little convoluted.
The relevant javascript objects are (assuming a select element called
"mySelect"):
mySelect.options = an array of the option elements
mySelect.selectedIndex = the index of the selected element
mySelect.options[mySelect.selectedIndex].value = the value of the selected
option

Subject: html:select and JavaScript problem
Hello struts-user,
I want to write a selected element from a PullDown in a text form. I
use a JavaScript funktion to do this. This funktion is excecuted
when someone click on a element from the PullDown. (or perhaps not
excecuted?)
The problem is now, nothing is written in the text field.
JavaScript funktion in the header area:
<script language="JavaScript">
<!--
function setArtist(artistStr){
document.forms[0].artist.value=artistStr;
}
//-->
</script>
PullDown and text field:
<html:text property="artist" size="40"/>
<html:select property="artist" onclick="javascript:setArtist(value);">
<html:options collection="artist" property="value" labelProperty="label"/>
</html:select>
Have someone a idea to solve this problem???
