Question

how to disable style for element already has styled with css by element name and I can’t make the same same style by etering a class name in css just #ElementName which style attribute doesn’t shown on html code?

Answer 1

You could try:

$("selector").removeAttr("style");

but my question is: why do you want to remove CSS styles? Usually this is a sign that you’re not doing something in a good way. Like some will write code like this:

$("selector").hover(function() {
  $(this).css("background", "red");
}, function() {
  // ???
});

The problem of course is that you don’t know what to set the background to in order to reset it to normal. That’s why you should use classes:

div.highlight { background: red; }

with:

$("selector").hover(function() {
  $(this).addClass("highlight");
}, function() {
  $(this).removeClass("highlight");
});

Problem solved.

So I can’t comment on your approach because you haven’t provided enough detail for that but in my experience questions like “how do I remove a style?” are a red flag.
