我需要在同一页面上有多个画廊(带标题),并且一直在尝试实现此 javascript,但我无法获取下一个 |之前的链接适用于任一画廊。 JavaScript 新手 - 有什么建议吗?
这是 fiddle :http://jsfiddle.net/astHh/11/
HTML:
<div style="text-align: center">
<!-- Place the first image here -->
<img src="http://www.cool-smileys.com/images/out11.jpg" id="mypic" name="mypic" alt="information" border="0" height="150" width="200">
<br>
<!-- Place the text for the first image here --><div id="burns">Caption one</div>
<p>
<a href="#" onclick="S2.UpDown(-1); return false;">« Previous</a> |
<a href="#" onclick="S2.UpDown(1); return false;"> Next »</a>
</div>
<p>
<div style="text-align: center">
<!-- Place the first image here -->
<img src="http://www.cool-smileys.com/images/out13.jpg" id="mypic2" name="mypic2" alt="information" border="0" height="150" width="200">
<br>
<!-- Place the text for the first image here --> <div id="burns2">Caption two</div>
<p>
<a href="#" onclick="S2.UpDown(-1); return false;">« Previous</a> |
<a href="#" onclick="S2.UpDown(1); return false;"> Next »</a>
</div>
Javascript:
<script type="text/javascript">
function SimpleSlideShow(o){
this.img=document.getElementById(o.ImageID);
this.txt=document.getElementById(o.TextID);
this.ary=o.Array||[];
this.cnt=0;
}
SimpleSlideShow.prototype.UpDown=function(ud){
this.cnt+=ud;
this.cnt=this.cnt<0?this.ary.length-1:this.cnt==this.ary.length?0:this.cnt;
if (this.ary[this.cnt]){
if (this.img&&this.ary[this.cnt][0]){
this.img.src=this.ary[this.cnt][0];
this.img.alt=this.ary[this.cnt][1];
}
if (this.txt){
this.txt.innerHTML=this.ary[this.cnt][2]||'';
}
}
}
S1=new SimpleSlideShow({
ImageID:'mypic',
TextID:'burns',
Array:[
['http://www.cool-smileys.com/images/out11.jpg,' 'Caption one', 'The beautiful mountains'],
['http://www.cool-smileys.com/images/out10.jpg','Caption two','The crystal clear lake'],
]
});
S2=new SimpleSlideShow({
ImageID:'mypic2',
TextID:'burns2',
Array:[
['http://www.cool-smileys.com/images/out13.jpg','caption one', 'The beautiful mountains'],
['http://www.cool-smileys.com/images/out12.jpg','caption two','The lonesome, barren tree']
]
});
</script>
最佳答案
您的 JavaScript 中有多个语法错误:
从脚本 Pane 中删除:
<script type="text/javascript">
</script>
在“S1”的定义中,您缺少一个逗号(就在“标题一”之前):
S1=new SimpleSlideShow({
ImageID:'mypic',
TextID:'burns',
Array:[
['http://www.cool-smileys.com/images/out11.jpg,','Caption one', 'The beautiful mountains'],
['http://www.cool-smileys.com/images/out10.jpg','Caption two','The crystal clear lake'],
]
});
然后在 HTML Pane 中,您应该将第一组上一个/下一个链接更新为目标 S1 而不是 S2。
