Question

我有一个JavaScript可以打开DIV作为弹出窗口。但现在我想打开来自不同DIVS的几个不同的弹出窗口，我无法让它正常工作。

我使用以下JavaScript：

<script>
window.onload = function()
{
    var show = document.getElementById('show-div');
    var hide = document.getElementById('hide-div');
    var popup = document.getElementById('popup-div');

    show.onclick = function(e)
    {
        popup.style.visibility = 'visible';
        return false;
    }

    hide.onclick = function(e)
    {
        popup.style.visibility = 'hidden';
        return false;
    }
}
</script>

对于div我使用以下代码：

<a id="show-div" href="#">link</a>
<div id="popup-div">
<div id="popup-header">
<div id="popup-title">...Popup title...</div>
<a id="hide-div" href="#">X</a></div>
<div id="popup-body">
<p>This is the content of the div....</p>
</div>
</div>

这适用于1个链接，但即使我使用不同的DIV ID（和关联的var元素，如＆＃34; var popup1 = document.getElementById（＆＃39; popup-div1＆＃39;）; ＆＃34;和popup1 onclick events）我无法正常工作。如何使用包含内容的所有DIV链接来使其工作。

（因为我无法回答我自己的问题，以下是我修复它的方法）我使用以下代码：

<script>
window.onload = function()
{
    var show = document.getElementById('show-div');
    var show2 = document.getElementById('show-div2');
    var hide = document.getElementById('hide-div');
    var hide2 = document.getElementById('hide-div2');
    var popup = document.getElementById('popup-div');
    var popup2 = document.getElementById('popup-div2');

    show.onclick = function(e)
    {
        popup.style.visibility = 'visible';
        return false;
    }

    show2.onclick = function(e)
    {
        popup2.style.visibility = 'visible';
        return false;
    }

    hide.onclick = function(e)
    {
        popup.style.visibility = 'hidden';
        return false;
    }
    hide2.onclick = function(e)
    {
        popup2.style.visibility = 'hidden';
        return false;
    }
}
</script>

和

<a id="show-div" href="#">link</a>
<div id="popup-div">
<div id="popup-header">
<div id="popup-title">...Popup title...</div>
<a id="hide-div" href="#">X</a></div>
<div id="popup-body">
<p>This is the content of the div....</p>
</div>
</div>
<a id="show-div2" href="#">link2</a>
<div id="popup-div2">
<div id="popup-header">
<div id="popup-title">...Popup title2...</div>
<a id="hide-div2" href="#">X</a></div>
<div id="popup-body">
<p>This is the content of the div2....</p>
</div>
</div>

Demo

JS代码：

var show = document.getElementById('show-div');
var hides = document.getElementsByClassName('hide-div');
var popups = document.getElementsByClassName("popup-div");

show.onclick = function (e) {
    for (var i = 0; i < popups.length; i++) {
        popups[i].style.visibility = 'visible';
    }
    return false;
}

for (var j = 0; j < hides.length; j++) {
    hides[j].onclick = function (e) {
        this.parentNode.parentNode.style.visibility = 'hidden';
        return false;
    }
}

HTML代码：

<a id="show-div" href="#">Show/Hide</a>

<div id="popup-div" class="popup-div">
    <div id="popup-header">
        <div id="popup-title">...Popup title...</div>
<a id="hide-div" class="hide-div" href="#">X</a>

    </div>
    <div id="popup-body">
        <p>This is the content of the div....</p>
    </div>
</div>
<div id="popup-div" class="popup-div">
    <div id="popup-header">
        <div id="popup-title">...Popup title...</div>
<a id="hide-div" class="hide-div" href="#">X</a>

    </div>
    <div id="popup-body">
        <p>This is the content of the div....</p>
    </div>
</div>
