Jquery If condition True add style visibility:hidden-CodePudding

I'm trying, if an "if" condition is true, to set the style of an element to "visibility:hide;".

I've done this:

if (user.privilege = 3) {
        $("#persone").css("visibility:hidden;");
}

But when the If condition runs, in the console i get this error:

"Uncaught TypeError: Cannot read properties of null (reading 'style')"

What should i do to solve this?

var html = '<div class= "col-lg-6">' 
           '<label >A chi è riferito l\'evento? </label>'  
                 '<select  id="persone" >'  
                    _this.GetOptionPersone()  
                 '</select >'  
           '</div>' ;

You've got a couple of syntax issues. Firstly = is for assignment. To compare values you need to use == or ===.

Secondly css() accepts 2 arguments, the rule name and its value, and it shouldn't have the trailing ;.

if (user.privilege == 3) {
  $("#persone").css('visibility', 'hidden');
}
