js in solving compatibility issues

Gets the event object compatible ie wording

1 var obox = document.querSelector(".box");
2 
3 obox.onclick = function(eve) {
4            var e = eve || window.event   //ie只支持window.event
5            console.log(e);
6         }

Stop the event bubbling ie compatible wording

. 1  function stopBubble (E) {     // incoming event object 
2          IF (e.stopPropagation) {
 . 3              e.stopPropagation ();
 . 4          } the else {
 . 5              e.cancelBubble = to true ;    // if ie, using e.cancleBubble 
. 6          }
 7      }

 

 Listening bindings compatible ie wording

. 1  function addEvent (ELE, type, CB) {    // element object event type function 
2          IF (ele.addEventListener) {    
 . 3              ele.addEventListener (type, CB)     // IE is not supported 
. 4          } the else  IF (ele.attachEvent) {
 . 5              ele.attachEvent ( "ON" + type, CB)    // only ie9 support 
. 6          } the else {
 . 7              ELE [ "ON" + type] = CB;    // do not support, using the assignment bindings 
8          } 
 9      }

 

Ie compatible with the wording unbind events

. 1  function removeEvent (ELE, type, CB) {    // element object event type function 
2          IF (ele.removeEventListener) {    
 . 3              ele.removeEventListener (type, CB)    // IE is not supported 
. 4          } the else  IF (ele.detachEvent) {
 . 5              ele.detachEvent ( "ON" + type, CB)    // IE support 
. 6          } the else {
 . 7              ELE [ "ON" + type] = null ;    // do not support, using the binding event to delete the assignment of formula 
8          }
 9      }
