While developing a website in Asp.net MVC4, I noticed that when my control is in focus inside a text-box or text-area, which are read only, it is moving to the parent of the current URL. In order to solve it i had written a JQuery below which will prevent the back to the parent URL in any browser and in any web developing programming languages.
$(document).keydown(function(e) {
var doPrevent;
if (e.keyCode == 8) {
var d = e.srcElement || e.target;
if (d.tagName.toUpperCase() == 'INPUT' || d.tagName.toUpperCase() == 'TEXTAREA') {
doPrevent = d.readOnly || d.disabled;
}
else
doPrevent = true;
}
else
doPrevent = false;
if (doPrevent)
e.preventDefault();
});
Enjoy!..........
