Struts1 - multibox uncheck action

[Chandran Madesh]

Hi,

In one of my jsp page, i am iterating some values with Multibox. As part of requirement, i need to populate the selected multibox value in another text box. Also the value needs to be removed from the text box when the corresponding multibox is unchecked.

I was able to make the first part(populate the value when a multibox is selected) working with the help of onclick JS function. But i couldn't make the second part work properly. I tried using hidden variable, JS array, but i could not get the value when a multibox is unchecked.

I want to know is there a way to get the value when a multi box unchecked.

Any suggestions / input would be appreciated.

Thanks in Advance,
Chandran

Is it resolved? If not, just a thought, to check or uncheck the multibox there is "onclick" action. why is it not possible to refresh the destination/selected list on every onclick action.

Hi Shankar,

Thanks for your post.

Already i tried this onclick action. As far as i know, the one option to get the selected value is iterate all the multibox and check is it selected, if <Multibox>.checked==true read the value. The below is the js function i used to read the Multibox value. This is working fine when the mutibox is selected. But when the Multi box is delected i couldn't get the value as the current deselected box fail for the .checked==true condition.

var sysWLlen = document.forms[0].sysselected.length;
	if(sysWLlen>0)
	for (i = 0; i <sysWLlen; i++) {
		{
			document.forms[0].sysselected[i].checked=false;
                                                // Do some more stuff

		}	
	}

Do you see any other option.

Which version of Struts is it 1.?

Also could you just post how you are calling js method in JSP, it would be helpful..

[Shankar Tanikella]

Try selected instead on checked.. Anyways I shall try in my local and let you know... I use Str.1.2

Ok, I just tried it in S1.2.. this should work, try it once

In JSP something like this

<html:select property="myFirstBoxList" name="myActionForm" multiple="true" onClick="selectItems(this.form['myFirstBoxList'],this.form['mySecondBoxList'])">
      <logic:iterate id="sourceList" property="myFirstBoxList" name="myActionForm" scope="..."> 
	      <option value="someIndex">Shankar</option>
      </logic:iterate>
</html:select> 

in js, I just got stuck/stumped with the options though. Here the tutorial is good (best one for you and you need not search anymore) and i just used it...

fun selectItems(sourceList, destinationList) {
	var index = 0;
	if (sourceList!=null && sourceList.options!=null) {
		if (destinationList!=null && destinationList.options!=null) 
			for (var i=0; i < destinationList.options.length; i++) {destinationList.options[i] = null;} // clean the selected list
		for (var i=0; i < sourceList.options.length; i++) {
			var element = sourceList.options[i];
			if (element.selected) { // if current element is selected add it to 2nd box
				destinationList.options[index] = new Option( element.text, element.value); index++;
			}
		}			
	}
}
