小弟我用javascript創建并提交的from為什么傳入Action里的from為null

我用javascript創建并提交的from為什么傳入Action里的from為null?
function   Obj_Util(BeanName,BeanClass,BeanMethod){
this.BeanName=BeanName;
this.BeanClass=BeanClass;
this.BeanMethod=BeanMethod;
this.paremeters=new   Array();
this.html=
' <div   style= "display:none "> \n '+
' <form   id= "UseBeanForm "   action= " '   +   Fn_GetCurrPath()   +   '../util.do?method=bean "   method= "POST "> \n '+
' <input   type= "text "   name= "view.name "   value= " '   +   this.BeanName   +   ' "/> \n '+
' <input   type= "text "   name= "view.type "   value= " '   +   this.BeanClass   +   ' "/> \n '+
' <input   type= "text "   name= "view.method "   value= " '   +   this.BeanMethod   +   ' "/> \n ';

Obj_Util.prototype.setParemeter=function   (paremeter){
this.paremeters[this.paremeters.length]=paremeter;
this.html=this.html+
' <input   type= "text "   name= "view.paremeter "   value= " '   +   paremeter   +   ' "/> \n ';
};
Obj_Util.prototype.getParemeter=function   (){
return   this.paremeters;
};
Obj_Util.prototype.submit=function   (){
this.html=this.html+
' </form> \n '+
' </div> \n ';
var   BodyHtml=document.body.innerHTML;
document.body.innerHTML=BodyHtml+this.html;
document.forms[ "UseBeanForm "].submit();
document.body.innerHTML=BodyHtml;
};
}

------解决方案--------------------
很多原因，看看你的配置有问题不，标签正确与否
------解决方案--------------------
action是根据的form的name，不是id,我看你只定义了id
