Hi,
this page explains how we can bring and show the metadata in dropdown list(in HTML page).
1. Download the latest SDK.
go to : SDK\SampleCode\JS\SOAPForJScript\SOAPForJScript\Scripts
check SDK.MetaData.js is there or not..
if yes :
2. Create a javascript webresource with name of : SDK.MetaData
example : new_/Scripts/SDK.MetaData.js (use same formate for naming)
3. attach the SDK.MetaData.js from bin folder.
4. now create a HTML webresource with name of : /MetaDataDemo.htm
example : new_/MetaDataDemo.htm (use same format for naming).
5. attach the file : SDK\SampleCode\JS\SOAPForJScript\SOAPForJScript\MetaDataDemo.htm
here you will see the start button.. by clicking on this we will get entities, by clicking on entity we will get attributes.
now need to modify according to our requirement.
copy paste this code on the html webresource;
