formAPI + Image path validation

hi friends,

i know its a silly question but this peice of code is not running though i have run it many a times in past. function is not called by IWEventRegistry.addItemHandler.

<script language="java-script">
<![CDATA[

var root = '/templatedata';
IWEventRegistry.addItemHandler("/root/picture","onItemChange",pathset);

function pathset(item){
if(item.getValue().substring(0,root.length)==root){

item.setValue(item.getValue().substring(root.length));
IWDataCapture.refresh();
}
}

]]>
</script>

rgds,

Sachin -

What do you want the pathset function to do?

Hi Bjorn,
I want this function to remove " templatedata " from imagepath.

I am not sure if I understand the whole picture, but if all you need to do is remove a certain string value from another string value, then either replace the value using indexes and substrings or use a javascript regular expression.

I haven't tested this code, but it could get you started.

<script>
//literally create regex object
// true if "/templatedata" is at beginning
rootRegEx = /^\/templatedata/;

IWEventRegistry.addItemHandler("/root/picture","onItemChange",pathset);

function pathset(item){

var itemValue = item.getValue().;

// test method returns boolean if there is match
if (rootRegEx.test(itemValue){
// replace method (of String object) uses a regex to replace
var itemValue = itemValue.replace(rootRegEx,"");
item.setValue(itemValue);
}
}

</script>
