jQuery Forum

I am working on web accessibility.

I need to change(set if not exist) aria-hidden attribute when call JQuery Show()/Hide() functions. This is showHide function from JQuery 1.9.1

I added only 2 lines of code:

1. elem.setAttribute("aria-hidden", "false");

2. elem.setAttribute("aria-hidden", "true");
   This is working but I am not sure will this work in all browsers? http://www.w3schools.com/jsref/met_element_setattribute.asp It looks that IE8 an earlier does not support setAttribute method.  

3. function showHide(elements, show) {
       var display, elem, hidden,
       values = [],
       index = 0,
       length = elements.length;
       for (; index < length; index++) {
           elem = elements[index];
           if (!elem.style) {
               continue;
           }
   
           values[index] = jQuery._data(elem, "olddisplay");
           display = elem.style.display;
           if (show) {
               // Reset the inline display of this element to learn if it is
               // being hidden by cascaded rules or not
               if (!values[index] && display === "none") {
                   elem.style.display = "";
               }
   
               // Set elements which have been overridden with display: none
               // in a stylesheet to whatever the default browser style is
               // for such an element
               if (elem.style.display === "" && isHidden(elem)) {
                   values[index] = jQuery._data(elem, "olddisplay", css_defaultDisplay(elem.nodeName));
               }
               elem.setAttribute("aria-hidden", "false");
           } else {
   
               if (!values[index]) {
                   hidden = isHidden(elem);
   
                   if (display && display !== "none" || !hidden) {
                       jQuery._data(elem, "olddisplay", hidden ? display : jQuery.css(elem, "display"));
                   }
               }
               elem.setAttribute("aria-hidden", "true");
           } 
       }
