复制代码 代码如下:

var $d = document;

function $i(s){return $d.getElementById(s);}

var _jsc={}

_jsc.client=(function(){

var t={};

var b=navigator.userAgent.toLowerCase();

t.isOpera=(b.indexOf('opera')>-1)

t.isIE=(b.indexOf('msie')>-1)

t.isFF=(!t.isOpera&&!t.isIE&&b.indexOf("firefox")>-1);

return t;

})()

_jsc.util=(function(){

var t={}

t.addEvent=function(o,e,f){

if(_jsc.client.isIE){

o.attachEvent("on"+e,f)

}else{

o.addEventListener(e,f,fasle);

}

return true

}

return t;

})();

//window.onload=function(){_jsc.util.addEvent(document,"click",showMsg("z","d"))}

_jsc.util.addEvent(document,"click",function(){showMsg("a","b")})

function showMsg()

{

//alert(typeof arguments)

//var dd=[arguments[0],arguments[1]]

//var o = {a:'aa', b:'bb', c:'cc'};

//var o = {};

o=arguments

o=Array.prototype.slice.call(arguments,0);

for(var p in o)

{

alert(o[p]);

}

循环对象的所有属性:

<script>

var o = {a:'aa', b:'bb', c:'cc'};

for(var p in o)

{

alert(eval("o." + p));

}

</script>

循环数组的所有元素:

<script>

var arr = ['11', '22', '33'];

for(var i in arr)

{

alert(arr[i]);

}

</script>
