Using jquery to implement IE down backspace equivalent to return operation _jquery

In fact, said disable is not completely disabled, the back key in the browser defaults to click the Back button, as long as the normal text input can also be used, in other cases the BACKSPACE key is banned. See jquery Implementation code:

Copy Code code as follows:

$ (function () {
function Dokey (event) {
var ele = Event.target;
var elename = Ele.nodename;
var flag = true;
if (elename== "INPUT" | | elename== "TEXTAREA" | | elename== "SELECT") {
var re = $ (ele). attr ("ReadOnly");
if (re) {
Flag = true;
}else{
Flag = false;
}
}
if (Event.which==8&&flag) {
Event.preventdefault ();
Event.stoppropagation ();
}
}
$ (document). KeyPress (Dokey). KeyDown (Dokey);
});
