javascript-Internet Explorer 8及更低版本中的jQuery切换错误

Question

In internet explorer <=8 i got toggle error. I am using jquery-1.7.1. Thanks! JS code:

function myFunction1() {
    document.getElementById("dropdown-content1").classList.toggle("show");
}

So when press <a onclick="myFunction1()" id="shopbtn" href="#">Shop</a> it should add show class to block with id dropdown-content1 .

Answer 1

You aren't using any jQuery functions in that code. Everything in it is standard JavaScript and DOM.

classList is too new for IE8 to support (and IE8 is too old for Microsoft to support ).

If you wanted to use jQuery then you could use:

jQuery("#dropdown-content").toggleClass("show");
