Question

$("#EMPLOYEE_ALT option:[value='"+$("#EMPLOYEE_ID").val()+"']").remove();

the above code gives the following error:

Uncaught Error: Syntax error, unrecognized expression: #EMPLOYEE_ALT\ option:[value='9999']

9999 is employee id witch is correct and this value suppose to be sent via ajax and return with something.

$.post("url", { emp: $("#EMPLOYEE_ID").val(),ajax: "yes"  },

Answer 1

You have unexpected : in your selector. The correct selector would be

$("#EMPLOYEE_ALT option[value='"+$("#EMPLOYEE_ID").val()+"']").remove();
