夺命雷公狗---javascript NO:11 事件对象1
IE模型浏览器下:
事件对象 = window.event
W3C模型浏览器下:
DOM对象.事件 = function(event) {
事件对象 = event;
}
示例代码:
<!DOCTYPE html> <html> <head> <meta charset=’utf-8′> <title></title> <script src=’public.js’></script> <script> window.onload = function(){ $(‘btnok’).onclick = function(event){ //IE模型浏览器 //var event = window.event; alert(event); } } </script> </head> <body> <input type=’button’ id=’btnok’ value=”点击”> </body> </html>
如何解决兼容性问题
示例:
<!DOCTYPE html> <html> <head> <meta charset=’utf-8′> <title></title> <script src=’public.js’></script> <script> window.onload = function(){ $(‘btnok’).onclick = function(event){ if(window.event){ alert(window.event); }else{ alert(event); } } } </script> </head> <body> <input type=’button’ id=’btnok’ value=”点击”> </body> </html>
