I also do something similar. If a textbox changed I want to set a
related hidden field to true. I wrote a javascript function that simply
knows how my html field names are going to be structured. It then can
parse out the name in order to get the index.
JavaScript:
/* Take a field and the name of another field and set the
other field to true. Assume indexed tags and mapped properties.
*/
function setStringProperty(fld, strName)
{
fname = fld.name;
first = fname.substring(0, fname.indexOf("("));
changeName = first + "(" + strName + ")";
document.forms[fld.form.name].elements[changeName].value = "1";
}
JSP:
<slogic:iterate id="component" name="ComponentsForm" property="components">
<td>
<font size="-1">Delete</font>
<shtml:text name="component" property="property(beginDate)"
indexed="true"
onchange="setStringProperty(this, 'changeFlag')" />
</td>
</slogic:iterate>
The above jsp snippet produces html that looks like:
<input type="hidden" name="clinSuppBLimit[0].property(changeFlag)"
value="0">
<input type="text" name="clinSuppBLimit[0].property(effectiveDt)"
value="09/01/2001" onchange="setStringProperty(this, 'changeFlag')">
