放在文档最下面。<script type="text/javascript">
(function(){
var bind = function(object, fun){
return function(){
return fun.apply(object, arguments);
}
}; var addEvent = function(oTarget, sEventType, fnHandler){
if( oTarget.addEventListener){
oTarget.addEventListener(sEventType, fnHandler, false);
}else if( oTarget.attachEvent ){
oTarget.attachEvent("on" + sEventType, fnHandler);
}else{
oTarget["on" + sEventType] = fnHandler;
}
};

var onfocus = function(){
this.blur && this.blur();
}; var text = "a,input,area,img", type = "button,image,submit";
var arr = text.split(","), tag;
for(var i = 0; i < arr.length; i++){
tag = document.getElementsByTagName(arr[i]);
for(var j = 0; j < tag.length; j++){
if(!(arr[i] == "input" && type.indexOf(tag[j].type) < 0)){
addEvent(tag[j], "focus", bind(tag[j], onfocus));
}
}
}
})();
</script>
