其中有两个函数需要引用外部公共文件
$查找对象的，这个不多说。另外个是toInt转换成数字，代码如下
String.prototype.trim = function(){return this.replace(/^\s+|\s+$/g,"");}
String.prototype.toInt = function(){var r = this.trim().replace(/\D/gi,"0"); return(r.length>0?parseFloat(r):0)}
String.prototype.toInt = function(){var r = this.trim().replace(/\D/gi,"0"); return(r.length>0?parseFloat(r):0)}
代码比较简单，ie8和firefox3.5测试通过，ie6的话应该有被select遮挡的问题，后期有必要在做处理，然后对初始化值的正确性未做判断
代码随便使用，任意修改，莫有版权
