Assign a value to hidden field in Jquery

Hi I am trying to assign the value from a select input to a hidden field using jquery, although I keep receiving an invalid left hand side of operator. I tried using the hiddenProgramIds.ClientId, but only received an error. Can someone shed a little light. Thanks.

$("#programSelector").on('click', function addProgram() {
    $("<%= hiddenProgramIds %>").val() = $('#programSelector').val();
});
<asp:HiddenField ID="hiddenProgramIds" runat="server" Value="" />

You don't set a value with = in jQuery, you pass the string as an argument to the val() function, like this

$("#programSelector").on('change', function() {
    $("#<%= hiddenProgramIds.ClientID %>").val( this.value );
});

and if #programSelector is in fact a select element, you should be using the change event, not click

You need use ClientId to JQuery works

 $("#<%= hiddenProgramIds.ClientID %>").val( this.value );
