Solution 1

The code

JavaScript

$(strID)[0].value

is pointing to value property of first element with id equal to ID.
Note, that there is no “o”, but “0” (zero) in brackets, which indicates Array type of variable.

UPDATE:
In the $.get ... line you are providing the “Mode” property into your GET AJAX call with value mentioned above.

JavaScript

$.get('Dynamic_page.aspx', { Id: ID, Mode:$(strID)[0].value }, function() {});

Id and Mode are the Parameters/Data (whose values are ID and $(strID)[0].value respectively) you are passing to Dynamic_page.aspx Page.

Refer - jQuery.get()[^]
Go to - Examples -> Example -> Request the test.php page and send some additional data along (while still ignoring the return results).

Please tell me what this Ajax Methord -$.get('Dynamic_page.aspx', { Id: ID, Mode:$(strID)[0].value }, function() { }) is doing
