I have one custom property say XYZ. I want to validate it on blur event. I am calling one web-script using Ajax from JavaScript(Client) but its not waiting for

You need to use the callbacks available on the function as these are called after the operation has completed. You have one failureCallback and one successCallback.

Here is an example of a JavaScript jsonPost function using a successCallback:

Alfresco.util.Ajax.jsonPost(
    {
        url: Alfresco.constants.PROXY_URI + "my/webscript?nodeRef=" + nodeRef,
        successCallback: {
            fn: function (o) {

                //Make further calls

            },
            scope: this
        },
        failureMessage: "Server Error"
    });

If you want to block further code then you need to overwrite the relevant part of Alfresco and move the calls to the callback.
