ArraySlice不能用在DOM集合中，若加if判断心里则又不爽，故写此脚本以修复之

(function(){
/**
 * fix IE(lte 8) script error of ArraySlice called on HTMLCollection||NodeList
 */
try{Array.prototype.slice.call(document.forms)}catch(_){
	var parseArray=function(obj){
		if(obj instanceof Array)return obj;
		var l=obj.length>>>0,arr=new Array();
		for(var i=0;i<l;i+=1)arr.push(obj[i]);
		return arr;
	};
	var ArraySlice=Array.prototype.slice;
	Array.prototype.slice=function(){
		if(this===window||this===null||this===undefined){
			throw new Error("Array.prototype.slice called on null or undefined");
		}
		return ArraySlice.apply(parseArray(this),arguments);
	}
}
})();

若有高招，欢迎批评！
