今天在英文版的开发环境下，JS提示如果出现如果有中文，则中文一直是乱码，
弄了好半天才改好，在此记录一下：
在<script>上加上 “charset="GBK"”
如下所示：
<script src="JS/LoginCheck1.js" type="text/javascript" charset="GBK" language="javascript"></script>
挺好用的，希望能对其它人有所帮助！ ......

当函数调用如 var = add(1,2)，此时函数的指针会指向全局函数
var add = function(a,b){
return a + b;
};
var myObject = {
value:3,
getValue:function(){
return this.value;
}
};
myObject.double = function(){
var that = this;
var helper = function (){
//add方法内地this指向window对象，应该算是javascript设计错误
//所以这里用一个局部变量指向内部方法参数
that.value = add(that.value,that.value);
};
helper();
};
myObject.double();
document.writeln(myObject.getValue()); ......
