Javascript 正在将img标记添加到已打开的img标记上

Javascript 正在将img标记添加到已打开的img标记上,javascript,jquery,html,Javascript,Jquery,Html,请原谅这个模糊的问题标题。我不太清楚怎么用这个词 基本上,我的问题源于一点jquery,其中在html中设置数据属性时,img标记会显示一些奇怪的行为,如下所示 <img src="images/gallery/ <img src="/images/gallery/bob.png" class="thumbnail&quot; data="1"> " class="popupImage"> 这是您的问题:imgSrc=“/imag

请原谅这个模糊的问题标题。我不太清楚怎么用这个词

基本上,我的问题源于一点jquery,其中在html中设置数据属性时,img标记会显示一些奇怪的行为,如下所示

<img src="images/gallery/
                <img src="/images/gallery/bob.png" class="thumbnail&quot; data="1">
" class="popupImage">

这是您的问题:
imgSrc=“/images/gallery/”++$(“a[data=”“+id+”]).html()虽然我不确定你期望这行代码实际做什么。实际上问题在于你的php。将其更改为$item['image'],然后查看发生了什么在第一条语句中您分配给
imgSrc
的是什么<我同意@RoryMcCrossan,
imgSrc=“/images/gallery/”+$(“a[data=”“+id+”]).html()返回标记内的所有内容,我认为这是完整的,仅获取数据值。或者更简单地说是
imgSrc=“/images/gallery/”+id
@RoryMcCrossan和Dave(不能这样评价你)感谢你们两人的帮助,没有想过要改变这一点。当我想不出什么的时候,我的视力很差。所以,最好的答案还是你们两个。
