JavaScript

I need to get the value of an item in a dcr once the DCT is loaded.
Do I do this in the begining of the javascript?
Do I do it in the init() function?
Do I need to register some sort of event?

var item1 = IWDatacapture.getItem("/Name");
var nameVal = item1.getValue();

It would look somehting like this...

<script language="javascript">
<![CDATA[

function init() {
IWEventRegistry.addItemHandler("/Name", "onItemChange", get_item);
get_item(IWDatacapture.getItem("/Name"));
}

]]>

Keep in mind, now you have only "got" the item. I assume you want to do something with it.

Good Luck

There's always a catch!

How do you capture the value of DCT an item in an select (drop down list box) ? I have the JS code in place, but need to extract the text value, not the JS index value.

This is a drop down with a list of available hours
var capturestart = IWDatacapture.getValue("/Hour Start Time");

I don't the precise code - but I think you'd have to do a getItem("/Hour Start Time") along with the getValue("/Hour Start Time") - presumably the first call would provide a javascript array from which you could then extract the value associated with the index from the second call. This is just a guess...

If you get the value on change, it should return the "value" in the select option. It would look like this..

IWEventRegistry.addItemHandler("/location", "onItemChange", tell_it_to_me);

tell_it_to_me(item) {
var loc = item.getOptions()[item.getValue()].value
alert(loc);
}
