Question

需要一些帮助。这看起来像一段简单的代码，但我很难过为什么事情没有正常工作。 onClick事件showdiv（n）工作得很好。但onClick事件hidediv（）没有。有点奇怪的是，如果我在Firebug控制台上输入“hidediv（1）”，那么javascript语句就可以了。但是，当单击附加事件的div时，不会执行js代码。这是代码：

<script type="text/javascript">
function showdiv(n){
    switch(n){
        case 1:
        var div = document.getElementById("menucontent");
        div.setAttribute("class","menucontent_v");
        break;
        case 2:
        var div = document.getElementById("biographycontent");
        div.setAttribute("class","biographycontent_v");
        break;
        case 3:
        var div = document.getElementById("productscontent");
        div.setAttribute("class","productscontent_v");
        break;
        case 4:
        var div = document.getElementById("thankyoucontent");
        div.setAttribute("class","thankyoucontent_v");
        break;
        case 5:
        var div = document.getElementById("specialscontent");
        div.setAttribute("class","specialscontent_v");
        break;
        case 6:
        var div = document.getElementById("contactcontent");
        div.setAttribute("class","contactcontent_v");
        break;
        case 7:
        var div = document.getElementById("gallerycontent");
        div.setAttribute("class","gallerycontent_v");
        break;}}

function hidediv(n){
    switch(n){
        case 1:
        var div = document.getElementById("menucontent");
        div.setAttribute("class","menucontent_h");
        break;
        case 2:
        var div = document.getElementById("biographycontent");
        div.setAttribute("class","biographycontent_h");
        break;
        case 3:
        var div = document.getElementById("productscontent");
        div.setAttribute("class","productscontent_h");
        break;
        case 4:
        var div = document.getElementById("thankyoucontent");
        div.setAttribute("class","thankyoucontent_h");
        break;
        case 5:
        var div = document.getElementById("specialscontent");
        div.setAttribute("class","specialscontent_h");
        break;
        case 6:
        var div = document.getElementById("contactcontent");
        div.setAttribute("class","contactcontent_h");
        break;
        case 7:
        var div = document.getElementById("gallerycontent");
         div.setAttribute("class","gallerycontent_h");
        break;}}

一切似乎都很好，但事件并没有发生，我完全不知道为什么。

这是CSS：

Answer 1

我认为这是因为z-index将背景放在所有内容的前面，所以后面的任何内容都无法点击

HTML onClick事件不会触发
