Multiselect drop down not cleared value after selecting other option
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}
I have two drop down lists,if I select value from first dropdown, id will be passed to second dropdown which is multiselect dropdown of Bootstrap .
The problem is if that id doesn't have record in database that shows previously selected values.
I have tried .empty(),refresh etc but it doesn't show the proper result.
Please help..
Code is below:
var ID = $("#AreaMasterID").val();
$.ajax({
url: '../AllocateDump/FillDumpingSite',
type: "POST",
data: {
"AreaMasterID": ID
},
async: false,
dataType: "json",
success: function(res) {
if (res.length == 0) {
$("#DumpID").val('0');
$("#DumpID").val(' ');
//$("#DumpID").multiselect('refresh');
// $("#DumpID option").remove();
//$("#DumpID").multiselect('destroy');
} else {
for (var i = 0; i < res.length; i++) {
$("#DumpID").empty()
.append($("<option></option>")
.val(res[i].DumpingSiteID)
.html(res[i].DumpSiteName));
}
$('#DumpID').multiselect({
includeSelectAllOption: true
});
}
$("#DumpID").multiselect('refresh');
},
error: function(err) {
$.kanNotify.error(err);
},
});
In span it display selected values which are not cleared by .empty() and other options.
