I hope this will help you:
$(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.
