ajax - Simple jQuery function not working -

basically, i've got ajax call returning data based on ajax request such :

var thisid = jquery(this).data("id"); jquery.ajax({     type: "get",     url: pluginurl + "/****/templates/files/ajax_controller.php",     data: "ajaxaction=addid&id=" + thisid,     success: function(data) {         if(data === "success") {                         var oldid = jquery("input").find("[data-id='" + thisid + "']");             if(oldid) {                 alert("valid oldid!");                 oldid.val("added!");                 oldid.attr('disabled', 'disabled');             }     } }); 

what's happening alert() executing, not val() or attr it's simple i'm overlooking

i believe you've got bit wrong.

var oldid = jquery("input").find("[data-id='" + thisid + "']"); 

the above looks elements matching [data-id='" + thisid + "'] inside <input>s.

try replacing with:

var oldid = jquery("input[data-id='" + thisid + "']");

plus, pointed out user roasted, if condition incorrect. should be:

if(oldid.length > 0) { ... }
