推荐答案

这就是诀窍，

Here is the trick,

<div id="div1" style="position:absolute;top:80px;left:20px;width:80px;height:30px;display:none;">DOT.NET</div>
<div id="div2" style="position:absolute;top:80px;left:20px;width:80px;height:30px;">ASP.NET</div>
<input type="button" id="btn1" value="Change State" onclick="changeState();" />
        
<script type="text/javascript">
            function changeState() {
                if (document.getElementById("div1").style.display == "none") {
                    document.getElementById("div1").style.display = "";
                    document.getElementById("div2").style.display = "none";
                }
                else {
                    document.getElementById("div2").style.display = "";
                    document.getElementById("div1").style.display = "none";
                }
            }
</script>

因此，您可以在每个div中放置两个控件.

希望这会有所帮助.
