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"); } } .............. ...................... return elements; }
