Retrieve the Item ID from the Task List Related Item column

Question

Using JSOM, I getting all the task details which are not started. Using CAML query i got all the column values including related item column from Task list

var relateditm = $(this).attr("ows_RelatedItems");
alert(relateditm);

The value i got is

[{"ItemId":6,"WebId":"da019015-45eb-cd62-83e2-dfb360620954","ListId":"25ca3434-de22-4ccf-8954-6564cc179ea6"}];

I want the Item ID alone. How can i retrieve the id from this?

I tried with the below code, but undefined error is coming

var relateditmid = relateditm[0].ItemId;

Answer 1

Base on your code, the value you get is a string not an object.

so the code : var relateditmid = relateditm[0].ItemId; will return the item ID after converting the string relateditm to Object using eval funtion.

var relateditmObj = eval(relateditm);
var relateditmid = relateditmObj[0].ItemId;
