firstly I found java script Part with id = “demo-select2-1” in theme’s scripts then I redefine same function with New Name and use new id in other DropDownListFor:
@Html.DropDownListFor(model => model.MemberInstance.MemberType_Id, new SelectList(Model.MemberTypeList, "Id", "Title"), new { @id = "demo-select2-1", @class = "form-control" })
@Html.DropDownListFor(model => model.SurgeryInstance.SurgeryType_Id, new SelectList(Model.SurgeryTypeList, "Id", "SurgeryTitle"), new { @id = "demo-select2-a", @class = "form-control" })
and also java script function is
function r() {
var b = a("#demo-select2-1");
b.select2({
dir: "rtl"
})
}
and my new function is
function r1() {
var b = a("#demo-select2-a");
b.select2({
dir: "rtl"
})
}
also I can use it for multiple elements with same way
solved Does not work java script for more than one element
