javascript - JQuery Selector not working, where looping does. Why? -


i have 2 jquery selectors used did not find desired option third "brute force" method did. @ complete loss why. each looked should of , validated document loaded when selector ran. tried each value , text in selector , got same result in page. html dynamically loaded using jquery load method below (where thetype value coming html select control) associated javascript:

var thetype = $('#tickettype option:selected').val(); var theid =  $("#id").val(); var url = '/systembuildsiteconfigs/' + thetype + '/' + theid;  $('#ticketdiv').html("");  $("#ticketdiv").load(url, function (response, status, xhr) {     if (status == "error") {         alert("there error loading " + thetype + " form");     }     else {         $.getscript("/scripts/siteconfig" + thetype + ".js", function () {         });     } });

the html select in question:

<select name="supportorganization" class="form-control" id="supportorganization">     <option value="">- please select -</option>     <option>auxiliary it</option>     <option>business intelligence</option>     <option>change management</option>     <option>engineering rnd</option>     <option>enterprise business solutions</option>     <option>enterprise solutions</option>     <option selected="selected">hosting</option>     <option>infrastructure , operations</option>     <option>manufacturing</option>     <option>professional</option>     <option>support</option> </select>

first selector statement:

$("#supportorganization").find('option[value="' + jsonobj.supportorganization + '"]').attr("selected", true);

second selector statement:

$('#supportorganization option[value="' + jsonobj.supportorganization + '"]').attr("selected", true);

what worked:

$('#supportorganization option').each(function (idx, ele) {     if ($(ele).val() == jsonobj.supportorganization)         $(ele).attr("selected", true); });

the page segment loads correctly , other javascript fires load html controls content executing expected. page type loads , fires correctly performing similar functions. using jsfiddle, both selectors show work correctly. found through testing was

  • the variable did have expected value.
  • the text selector did not work correctly on page
  • the value selector did select object. unable determine object , attr() method did not set target attribute value.

i can go found work, wanted find out why wouldn't work. guessing has dynamically loaded html , javascript?

the jquery .val() function uses "hook" <option> elements return text content of element if "value" attribute missing. <option> elements don't have "value" attributes, selector not match.
