javascript - Find previously selected value of drop down list on change event -

- 

function loaddata(id) { var employeeid = $.trim($("#employeeid").val()); var employeetype = $.trim($("#employeetype").val());  var obj = ""; var cityid = $.trim($("#ddlcity").val()); obj = new viewmodel1(employeeid, employeetype, 0, $.trim($("#deptname").val()), "", "", $.trim($("#sectionname").val()), cityid); var posteddata = json.stringify(obj);  loader(); $.ajax({     //...........     //........... })

}

i have above function , want selected value in element #ddlcity. above function called line below.

@html.dropdowngrouplistfor(m => m.cityid, model.groupedtypeoptions, new { name = "ddlcity", id = "ddlcityname", @onchange = "javascript:loaddata(this.value)" })

var cityid = $.trim($("#ddlcity").val()); giving me cityid of new selection in dropdownlist.

so how can cityid of selected value?

might post comment answer (too:).

have onchange store new value data- attribute/data-storage on select element. can pick in subsequent changes.

e.g. http://jsfiddle.net/trueblueaussie/blc12tu0/

$(".selector").change(function() {     // previous value (if any)     var prev = $(this).data("prev");     // store new value next time     $(this).data("prev",$(this).val());      $('#output').html(prev); }).each(function(){     // save initial dropdown value previous value (for each select)     $(this).data("prev", $(this).val()); });
