提交隐藏表单HTML [英] Submitting hidden forms HTML

问题描述

我想在将值输入到另一个表单的文本输入字段中时提交隐藏表单。

 < form name =TDISLabelFormtarget =fr1method ='POST'action =/ createLabelTDIS.do > 
< input type =hiddenname =lab_novalue =<％= lab_no％>> 
< input type =hiddenname =accessionNumvalue =<％= accessionNum％>> 
< input type =hiddenid =labelname =labelvalue =<％= label％>> 
 
< / form> 
< iframe style =height：1px; width：1px; border：none：id =fr1>< / iframe> 
< form name =ackFormmethod =postaction =/ UpdateStatus.do> 
 
< button type =buttonvalue =Label>标签< / button> 
< input type =textid =labelname =labelvalue =<％= label％>/> 
< input type =buttononclick =TDISLabelForm.submit（）value =Create> 
 
< / form> 
  

当我点击提交TDISLabelForm的创建按钮时，我想提交label的值。

感谢您的帮助。

>这是一个开始，让你在路上 http://en.wikipedia.org/wiki/XMLHttpRequest

 函数submitLable（lblval）{
 var payLoad = document.forms ['TDISLabelForm'] 
 .lab_no.value = document.forms ['ackForm'] 
 .label.value; //将可见的值传递给隐藏表单
 var request = requestObject（）; 
 request.open（POST，/createLabelTDIS.do，false）; //将值发布到createLabelTDIS.do，以便像往常一样进行进一步处理。 
 request.send（payLoad）; 
 
 
 
函数requestObject（）{
 if（window.XMLHttpRequest）
 return new XMLHttpRequest（）; 
 else if（window.ActiveXObject）
 return new ActiveXObject（Msxml2.XMLHTTP）; 
 else 
抛出错误（无法创建HTTP请求对象）; 
} 
 
< input type =buttononclick =submitLable（this）value =Create> 
  

I want to submit a hidden form when a value is entered into a text input field that is part of another form.

<form name="TDISLabelForm" target="fr1" method='POST' action="/createLabelTDIS.do">
                <input type="hidden" name="lab_no" value="<%=lab_no%>">
                <input type="hidden" name="accessionNum" value="<%=accessionNum%>">
                <input type="hidden" id="label" name="label" value="<%=label%>">

    </form>  
<iframe style="height:1px;width:1px;border:none:" id="fr1"></iframe>
<form name="ackForm" method="post" action="/UpdateStatus.do">

            <button type="button" value="Label">Label</button>
             <input type="text" id="label" name="label" value="<%=label%>"/>
             <input type="button" onclick="TDISLabelForm.submit()" value="Create">

 </form>

I want to submit the value of "label" when I click on the Create button that submits TDISLabelForm. How can this be done?

Thanks for your help.

解决方案

This is a start, to get you on your way http://en.wikipedia.org/wiki/XMLHttpRequest

function submitLable(lblval){
   var payLoad = document.forms['TDISLabelForm']
                         .lab_no.value = document.forms['ackForm']
                         .label.value; // pass the value for visible for to the hidden form
   var request = requestObject();
   request.open("POST", "/createLabelTDIS.do", false); // post the value to createLabelTDIS.do for further processing as usual.
   request.send(payLoad);
}


function requestObject() {
   if (window.XMLHttpRequest)
      return new XMLHttpRequest();
   else if (window.ActiveXObject)
      return new ActiveXObject("Msxml2.XMLHTTP");
   else
      throw new Error("Could not create HTTP request object");
}

<input type="button" onclick="submitLable(this)" value="Create">
