Javascript placeholders
嗯..我真的很喜欢javascript而且很挣扎。我的代码如下。使用更多代码更容易解释。所以基本上想要在每个占位符中显示每个图像,但是按照我点击它们的顺序。所以,如果我点击img 3,这将转到占位符1然后下一个我点击将转到占位符2,如果这是有道理的。 (这个棘手的位是一旦选择了一个选项我想再次不允许该选项。要么有错误消息说已经使用过或从列表中消失)
<script type="text/javascript" language="javascript">
function showPic (whichpic) {
if (document.getElementById) {
document.getElementById('placeholder1').src = whichpic.href;
document.getElementById('placeholder2').src = whichpic.href;
document.getElementById('placeholder3').src = whichpic.href;
if (whichpic.title) {
document.getElementById('desc').childNodes[0].nodeValue = whichpic.title;
} else {
document.getElementById('desc').childNodes[0].nodeValue = whichpic.childNodes[0].nodeValue;
}
return false;
} else {
return true;
}
}
</script>
<div style="border: 1px solid #999; padding: 1em; margin: 0 0 15px 0;">
<ul>
<li><a onclick="return showPic(this)" href="images/img1.jpg" title="img 1">img 1</a></li>
<li><a onclick="return showPic(this)" href="images/img2.jpg" title="img 2">img 2</a></li>
<li><a onclick="return showPic(this)" href="images/img3.jpg" title="img 3">img 3</a></li>
</ul>
<p id="desc">Choose an image to begin</p>
<img id="placeholder1" src="images/blank.gif" alt="" />
<img id="placeholder2" src="images/blank.gif" alt="" />
<img id="placeholder3" src="images/blank.gif" alt="" />
</div>
答案 0 :(得分:0)
您可以像这样删除<li>
。后:
if (whichpic.title) {
document.getElementById('desc').childNodes[0].nodeValue = whichpic.title;
} else {
document.getElementById('desc').childNodes[0].nodeValue = whichpic.childNodes[0].nodeValue;
}
之前:
return false;
添加:
var node = whichpic;
while(node.nodeName != 'LI' && (node = node.parentNode));
node.parentNode.removeChild(node);
