I’m starting on SharePoint Online development. So was examining what are the capabilities of ECMAScripts and what we can really achieve. So started simply to read some values from a SharePoint list.
In the below example I’m trying to retrieve list data and populate them inside a drop down.
In the markup I have one Dropdown list that will get populated with the list data, and a button to trigger the event for retrieving data and populating the dropdown.
I have bound the retrieveListItems method to onclick event of the button.
<select id=”ddlCategory”></select> <br />
<input type=”button” value=”GetData” onclick=”retrieveListItems();” />
Then I have written my ECMA Script in a script block as bellow.
