I have HTML multi-select options with few options bound from the database. user selects the
options & saves them in the database, now when a user visits the page I want the user to see their pre-selected values but
it works for hardcoded values like
var values = "1,2,3";
but for the same hidden values from the database, which are user's preselected it just show for the first one
// var values = hidden;
when var values = "1,2,3"; exactly the same as var values = hidden values then why am I not getting all options selected for hidden values? it just shows the first value selected
Please answer
My code is below :
$(function () {
var hdnvalues = "";
if ($.trim($('#<%=hfroles.ClientID %>').val() != "")) {
hdnvalues = $.trim($('#<%=hfroles.ClientID %>').val());
}
var values = "1,2,3";
// var values = hdnvalues;
$.ajax({
type: "POST",
url: "NotificationsNews.aspx/GetRoles",
data: '{}',
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (r) {
var ddlRoles = $("[id*=ddlRoles]");
$.each(r.d, function () {
ddlRoles.append($("<option></option>").val(this['Value']).html(this['Text']));
$.each(values.split(","), function (i, e)
{
$("#ddlRoles option[value='" + e + "']").prop("selected", true);
});
});
});
});
});
