// JavaScript Document
//加入列表框查找工能
//07.68.6 加入当没show的时候该控件不判断
//07.8.6加入对在线编辑器的支持
/*
使用例子
var F = Js_Form;
F.tabName = "show"
F.check(obj)  //赋给提交按钮 (如果点击是图片要加表单ID否则,不须) 
F.reset()  //赋给重置按钮
F.clear(id)  //设置表单项的自动清除,id为控件的id或控件对象(选填在控件内调用不填,控件外要填)
F.CreateSelect(this.value,"objId","sql") 注:sql中,空格用@代替如: "select@cid,model,id@from@product" 在下拉的onchange事件中调用
