javascript event兼容性随笔
一、前言
1 function ConvertEvent(e, element) { 2 var event = e || window.event; 3 var resultEvent = { 4 event: event, 5 type: event.type, 6 target: event.target || event.srcElement, 7 relatedTarget: event.relatedTarget || event.fromElement || event.toElement, 8 clientX: event.clientX, 9 clientY: event.clientY, 10 screenX: event.screenX, 11 screenY: event.screenY, 12 // offsetX: event.offsetX, 13 // offsetY: event.offsetY, 14 altKey: event.altKey, 15 ctrlKey: event.ctrlKey, 16 shiftKey: event.shiftKey, 17 charCode: event.charCode || event.keyCode, 18 charCodeValue: String.fromCharCode(event.charCode || event.keyCode), 19 stopPropagation: event.stopPropagation || function () { return window.event.cancelBubble = true; }, 20 preventDefault: event.preventDefault || function () { return window.event.returnValue = false; } 21 }; 22 23 return resultEvent; 24 } 25 26 var eventClass = window.Event = window.jasen.core.Event; 27 eventClass.Convert = ConvertEvent;
二、范例
<form id="form1" runat="server"> <div> <input type="text" value="mouse test" onkeydown="return convert(event);" /> <input type="button" value="mouse test" onclick="return convert(event,this);" /> </div> </form> <script type="text/javascript"> function convert(e) { var eventResult = Event.Convert(e); var result = ""; for (var p in eventResult) { result += (p.toString() + "\t\t --->" + (eventResult[p] == null ? "null" : eventResult[p]).toString() + "\n"); } alert(result); } </script>
