<script type="text/javascript">
checkCustomize  = function() {
    
    
        var a=jQuery("#field11604").val();//获取字段值,改成对应的字段可以了。
		var b=a.toString().replace(".","").substr(0,2);//截取值的前两位(0表示从第一位开始,2表示截取两位)
		var c=a.length;
		if(c>=2){
    
    //如果输入值大于等于两位,则可以继续进行
	         a=jQuery("#field11604").val(b);
                   return true;
		}else{
    
    //如果小于两位则无法保存
			alert("对不起,长度不够无法截取");
                     return false;
		}
}
