动态改变div的宽度
我正在尝试使用类似的脚本在单击图像更改(有效)时动态更改我的“内部”div 的宽度。我无法让脚本工作,任何修复它或更改它的帮助将不胜感激。我是 javascript 菜鸟,所以请保持友善;-)
<script type="text/javascript">
function setBase(baseval) {
var images = document.getElementById("mylist").getElementsByTagName("img");
for (var i = 0; i < images.length; i++) {
images[i].src = baseval + ((i<9)?0+i:i) + ".jpg";
}
}
</script>
<script type="text/javascript">
function setStyle(baseval) {
var style = document.getElementById("inner").getElementsByTagName("div");
for (var i = 0; i < images.length; i++) {
style[i].style = baseval + "px";
}
}
</script>
</head>
<body>
<div id="mylist" style=" height: 481px; width: 700px; overflow-x: auto; ">
<div id="inner" style="width: 7300px ">
<img src="carousel_img/1/1.jpg" height="450" />
<img src="carousel_img/1/2.jpg" height="450" />
<img src="carousel_img/1/3.jpg" height="450" />
<img src="carousel_img/1/4.jpg" height="450" />
<img src="carousel_img/1/5.jpg" height="450" />
<img src="carousel_img/1/6.jpg" height="450" />
<img src="carousel_img/1/7.jpg" height="450" />
<img src="carousel_img/1/8.jpg" height="450" />
<img src="carousel_img/1/9.jpg" height="450" />
<img src="carousel_img/1/10.jpg" height="450" />
<img src="carousel_img/1/0.jpg" height="450" />
<img src="carousel_img/1/11.jpg" height="450" />
</div>
</div>
<p>
<a href="#" onclick="setBase('carousel_img/1/'); setStyle('7300'); return false;">Set A</a>
<a href="#" onclick="setBase('carousel_img/3/'); setStyle('6300'); return false;">Set B</a>
</p>
I am trying to change my "inner" div's width dynamically on the click that the images are changed (which works) with a similar script. I cannot get the script to work, any help fixing it, or changing it would be appreciated. I am a noob in javascript so please be nice ;-)
<script type="text/javascript">
function setBase(baseval) {
var images = document.getElementById("mylist").getElementsByTagName("img");
for (var i = 0; i < images.length; i++) {
images[i].src = baseval + ((i<9)?0+i:i) + ".jpg";
}
}
</script>
<script type="text/javascript">
function setStyle(baseval) {
var style = document.getElementById("inner").getElementsByTagName("div");
for (var i = 0; i < images.length; i++) {
style[i].style = baseval + "px";

</div>
</div>

不要采取困难的方式。摆脱
inner
div 的固定宽度(这是所有不必要的 JavaScript 问题的原因),只需借助 CSS 的帮助即可解决它。更重要的是,内部 div 在技术上是多余的。这是一个 SSCCE,只需复制“粘贴”然后运行它:Don't do it the hard way. Get rid of the fixed width of the
inner
div (which is the cause of all that unnecessary JavaScript problems) and just solve it with help of a good shot of CSS. Even more, the inner div is technically superfluous. Here's an SSCCE, just copy'n'paste'n'run it:这个函数看起来不正确:
如果你想设置图像的宽度,那么这个:
应该看起来像这样:
否则,如果你想设置div本身的宽度,那么它应该看起来像这:
This function doesn't look right:
If you're trying to set the width of the images, then this:
should look like this:
Otherwise, if you're trying to set the width of the div itself, then it should look like this:
由于“inner”已经是一个div,因此无需调用getElementsByTagName。所以试试这个:(
由于“style”是一个关键字,我使用了不同的变量名)
Since "inner" is already a div, there is no need to call getElementsByTagName. So try this:
(Since 'style' is a keyword, I used a different variable name)
