我使用显示隐藏答案的代码，但是当我重复使用另一个答案的代码时，它指向过去的代码，我的网站只接受JS和HTML

我的代码是

my code is

<input type="button" onClick="javascript:ShowHide('HiddenDiv')"value='click here for answer'/>

</div>
<script type="text/javascript">// <![CDATA[
function ShowHide(divId)
{
if(document.getElementById(divId).style.display == 'none')
{
document.getElementById(divId).style.display='block';
}
else
{
document.getElementById(divId).style.display = 'none';
}
}
// ]]></script>

我的尝试：

What I have tried:

i try to repaste the code many times in the same page,but i tried to edit it with no use,so i need somebody help?

推荐答案

Ids必须是唯一的，如果你复制并通过该代码，你有两个id为HiddenDiv的项目，所以当你使用其中的HiddenDiv知道要返回的getElementById时？更改每个questoins上的id

Ids have to be unique, if you copy and past that code you have two items with id of HiddenDiv, so when you use getElementById which HiddenDiv is it to know to return? Change the id on each of your questoins

<input type="button" onClick="javascript:ShowHide('HiddenDiv1')"value='click here for answer'/>
<div class="mid" id="HiddenDiv1" style="display: none;"><font face="Arial" size="+2" color="#306Eff" align="right"> THE HIDDEN TEXTTHE HIDDEN TEXT THE HIDDEN TEXT THE HIDDEN TEXT THE HIDDEN TEXT THE HIDDEN TEXT THE HIDDEN TEXT THE HIDDEN TEXT THE HIDDEN TEXT THE HIDDEN TEXT THE HIDDEN TEXT 
</div>

<input type="button" onClick="javascript:ShowHide('HiddenDiv2')"value='click here for answer'/>
<div class="mid" id="HiddenDiv2" style="display: none;"><font face="Arial" size="+2" color="#306Eff" align="right"> THE HIDDEN TEXTTHE HIDDEN TEXT THE HIDDEN TEXT THE HIDDEN TEXT THE HIDDEN TEXT THE HIDDEN TEXT THE HIDDEN TEXT THE HIDDEN TEXT THE HIDDEN TEXT THE HIDDEN TEXT THE HIDDEN TEXT 
</div>

谢谢

但有没有办法编辑代码来做到这一点而不改变每个Q的id？
