select 2 dropdown set value jquery code example

Example 1: jquery to set value in select2 dropdown button

$("#u20_cre").select2().val(["1","6"]).trigger("change");

Example 2: how to set selected value in multiselect dropdown using jquery

I hope this will help you:

Demo

$(document).ready(function() {
$("select").multiselect({
   selectedText: "# of # selected"
});
var hidValue = $("#hidSelectedOptions").val();
alert(hidValue);
var selectedOptions = hidValue.split(",");
for(var i in selectedOptions) {
    var optionVal = selectedOptions[i];
    $("select").find("option[value="+optionVal+"]").prop("selected", "selected");
}
$("select").multiselect('reload');
});
EDIT

refresh has been removed from latest jQuery-MultiSelect. Using reload will solve the question now.
