定位没有点击处理程序的动态添加元素 [英] Targeting dynamically added elements without click-handler
问题描述
$ p
HTML：
< body>
< div class =container>
< figure class =special_imagesdata-effect =zoomdata-profiles =testdata-options =some options>
< img data-src =specialImage0.jpg/>
< img data-src =specialImage1.jpg/>
< img data-src =specialImage2.jpg/>
< img data-src =specialImage3.jpg/>
< img data-src =specialImage4.jpg/>
< / figure>
< div class =normal_images>
< img src =normalImage0.jpg/>
< img src =normalImage1.jpg/>
< / div>
< / div>
< / body>
special_image 图中的所有内容将由外部页面加载更改脚本，所以我对此没有影响（否则我的所有问题都不会存在）。
由外部脚本操纵的HTML：
< body>
< div class =container>
< figure class =special_images thumbs-bottomdata-effect =zoomdata-profiles =testdata-options =some options>
< div class =some classes>
< div>
<！ - 多层添加内容 - >
< / div>
< div class =缩略图缩略图水平>
< div class =缩略图缩略图水平>
< div class =thumbnailails-wrapper>
< ul style =some styles>
< li class =thumbnail-selected>< img src =specialImage0？someParameters>< / li>
< li>< img src =specialImage1.jpg？someParameters>< / li>
< li>< img src =specialImage2.jpg？someParameters>< / li>
< li>< img src =specialImage3.jpg？someParameters>< / li>
< li>< img src =specialImage4.jpg？someParameters>< / li>
< / ul>
< / div>
< / div>
< / div>
< / div>
< / figure>
< div class =normal_images>
< img src =normalImage0.jpg/>
< img src =normalImage1.jpg/>
< / div>
< / div>
< / body>
外部脚本添加了所有这些元素后，我需要追加 正常图像进入脚本创建的无序列表。
jQuery似乎找不到添加元素当我试图定位他们，即使我延迟功能，等待外部脚本完成工作。
我没有找到任何解决方案，这样做，我希望有人能帮助我。
jQuery on（）在这里不行，内容应该被自动移动，并且不会被点击处理程序触发。
提前感谢任何提示或线索。
您可以使用 MutationObserver 事件以检测何时外部脚本已经修改了special_images元素。
var targetNodes = $ .special_images）; var MutationObserver = window.MutationObserver || window.WebKitMutationObserver; var myObserver = new MutationObserver（mutationHandler）; var obsConfig = {childList：true，characterData：false，attributes：false，subtree：true}; // ---向观察者添加一个目标节点。只能在一个时间添加一个节点targetNodes.each（function（）{myObserver.observe（this，obsConfig）;}）; function mutationHandler（mutationRecords）{if（$（'。thumbnailails-wrapper'）。length）{ myObserver.disconnect（）; $（'。thumbnailails-wrapper ul'）。append（$（'。normal_images img'）。detach（））; }} setTimeout（function（）{$（'。special_images'）。append（'< div class =thumbnailails-wrapper>< ul>< / ul>< / div>'）}，3000 ）;
< script src =https：// ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js\"></script><body> < div class =container> < div class =special_imagesdata-effect =zoomdata-profiles =testdata-options =some options> < img data-src =specialImage0.jpg/> < img data-src =specialImage1.jpg/> < img data-src =specialImage2.jpg/> < img data-src =specialImage3.jpg/> < img data-src =specialImage4.jpg/> < / DIV> < div class =normal_images> < img src =normalImage0.jpg/> < img src =normalImage1.jpg/> < / DIV> < / div>< / body>
How can I target and append content to already dynamically added content?
HTML:
<body>
<div class="container">
<figure class="special_images" data-effect="zoom" data-profiles="test" data-options="some options">
<img data-src="specialImage0.jpg"/>
<img data-src="specialImage1.jpg"/>
<img data-src="specialImage2.jpg"/>
<img data-src="specialImage3.jpg"/>
<img data-src="specialImage4.jpg"/>
</figure>
<div class="normal_images">
<img src="normalImage0.jpg"/>
<img src="normalImage1.jpg"/>
</div>
</div>
</body>
Everything in the special_image figure will be changed on page load by an external script, so I don't have influence on this (otherwise all of my problems wouldn't exist).
HTML manipulated by external script:
<body>
<div class="container">
<figure class="special_images thumbs-bottom" data-effect="zoom" data-profiles="test" data-options="some options">
<div class="some classes">
<div>
<!-- multiple layers of added content -->
</div>
<div class="thumbnails thumbnails-horizontal">
<div class="thumbnails thumbnails-horizontal">
<div class="thumbnails-wrapper">
<ul style="some styles">
<li class="thumbnail-selected"><img src="specialImage0?someParameters"></li>
<li><img src="specialImage1.jpg?someParameters"></li>
<li><img src="specialImage2.jpg?someParameters"></li>
<li><img src="specialImage3.jpg?someParameters"></li>
<li><img src="specialImage4.jpg?someParameters"></li>
</ul>
</div>
</div>
</div>
</div>
</figure>
<div class="normal_images">
<img src="normalImage0.jpg"/>
<img src="normalImage1.jpg"/>
</div>
</div>
</body>
After the external script added all of those elements, I need to append the normal images into the unordered list created by the script.
jQuery can't seem to find the added elements when I try to target them, even if I delay the function and wait until the external script finished the job.
I did not find any solution to do this and I hope someone here can help me. The jQuery on() sadly doesn't work here, the contents should be moved automatically and are not fired by a click handler.
Thanks in advance for any tips or clues.
You can use MutationObserver events to detect when the external script has modified the special_images element.
var targetNodes = $(".special_images");
var MutationObserver = window.MutationObserver || window.WebKitMutationObserver;
var myObserver = new MutationObserver(mutationHandler);
var obsConfig = {
childList: true,
characterData: false,
attributes: false,
subtree: true
};
//--- Add a target node to the observer. Can only add one node at a time.
targetNodes.each(function() {
myObserver.observe(this, obsConfig);
});
function mutationHandler(mutationRecords) {
if ($('.thumbnails-wrapper').length) {
myObserver.disconnect();
$('.thumbnails-wrapper ul').append(
$('.normal_images img').detach()
);
}
}
setTimeout(function () {
$('.special_images').append('<div class="thumbnails-wrapper"><ul></ul></div>')
}, 3000);
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<body>
<div class="container">
<div class="special_images" data-effect="zoom" data-profiles="test" data-options="some options">
<img data-src="specialImage0.jpg" />
<img data-src="specialImage1.jpg" />
<img data-src="specialImage2.jpg" />
<img data-src="specialImage3.jpg" />
<img data-src="specialImage4.jpg" />
</div>
<div class="normal_images">
<img src="normalImage0.jpg" />
<img src="normalImage1.jpg" />
</div>
</div>
</body>
