blocks|key|4094335|text|基本上，当您实例化元素时|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4094336|$('.dialog-pop').sharePop()|code-block|syntax|javascript|4094337|它使用.dialog-pop在document中搜索元素，并按您所写的绑定事件。因此，如果有一个新的动态添加的元素，无论元素是否有首先实例化的选择器，sharePop函数都不知道该做什么。因此，与其添加类，不如直接实例化元素。|offset|length|style|CODE|4094338|$('#WebPartWPQ6_ChromeTitle+a').sharePop()|4094339|如果您需要使用所选的选择器，则事件委托是可行的。如果强制不能确定要使用的选择器，并且目前使用的是jQuery+1.7或更低版本，则.selector属性可能会有所帮助。|4094340|哦，有一点要注意的是，我认为销毁以前相同的事件--防止它执行两次，等等--+(尽管您使用preventDefault)是好的。|4094341|$.fn.sharePop+=+function()+{

++return+false
};|4094342|或者，如果您的版本jQuery大于1.7，则将选择器作为参数应用。还请注意，我使用命名空间事件来防止破坏其他已经附加的click事件。|4094343|$.fn.sharePop+=+function(selector)+{
++if+(typeof+OpenPopUpPage+==+'function'){

++}

++return+false
};|4094344|实际上，如果我不像$.fn.sharePop那样共享$('.dialog-pop').sharePop('refresh')或$('.dialog-pop').sharePop('destroy')之类的方法/API，而不是直接将事件绑定到文档上，那么我就永远不会创建这样的插件。|4094345|entityMap|0|LINK|mutability|MUTABLE|url|https://api.jquery.com/selector/^0|0|0|3|B|F|8|23|8|0|0|1T|9|1T|9|0|0|18|E|0|0|1N|5|0|0|9|D|Q|10|1R|10|0^^$0|@$1|2|3|4|5|6|7|18|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|19|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|1A|8|@$I|1B|J|1C|K|L]|$I|1D|J|1E|K|L]|$I|1F|J|1G|K|L]]|9|@]|A|$]]|$1|M|3|N|5|D|7|1H|8|@]|9|@]|A|$E|F]]|$1|O|3|P|5|6|7|1I|8|@$I|1J|J|1K|K|L]]|9|@$I|1L|J|1M|1|1N]]|A|$]]|$1|Q|3|R|5|6|7|1O|8|@$I|1P|J|1Q|K|L]]|9|@]|A|$]]|$1|S|3|T|5|D|7|1R|8|@]|9|@]|A|$E|F]]|$1|U|3|V|5|6|7|1S|8|@$I|1T|J|1U|K|L]]|9|@]|A|$]]|$1|W|3|X|5|D|7|1V|8|@]|9|@]|A|$E|F]]|$1|Y|3|Z|5|6|7|1W|8|@$I|1X|J|1Y|K|L]|$I|1Z|J|20|K|L]|$I|21|J|22|K|L]]|9|@]|A|$]]|$1|10|3|-4|5|6|7|23|8|@]|9|@]|A|$]]]|11|$12|$5|13|14|15|A|$16|17]]]]

Basically, when you instantiate the element

<pre><code>$('.dialog-pop').sharePop()
</code></pre>

It searches element with <code>.dialog-pop</code> in <code>document</code> and bind the event you as you've wrote. So, if there is a new dynamically added element, whether if the element has selector that firstly you instantiate with, the <code>sharePop</code> function does not have any idea what to do. So, rather than adding a class, directly instantiate your element.

<pre><code>$('#WebPartWPQ6_ChromeTitle a').sharePop()
</code></pre>

If you in a need to use selector chosen, event delegation is way to go. In case you forcibly cannot determine selector you're going to use and currently using jQuery 1.7 or below, <a href="https://api.jquery.com/selector/" rel="nofollow noreferrer"><code>.selector</code></a> property might help.

And oh, a thing to note is, I think destroy previously the same event -- to prevent it executing twice, and so forth -- (although you use <code>preventDefault</code>) is good.

<pre><code>$.fn.sharePop = function() {
 if (typeof OpenPopUpPage == 'function'){
 var selector = this.selector

 $(document).off('click').on('click', selector, function (e) {
 e.preventDefault()
 var href = $(this.attr('href'))

 if (href) {
 OpenPopUpPage($(this).attr('href'))
 }
 })

 return this
 }

 return false
};
</code></pre>

Or apply the selector as argument if your version jQuery is greater than 1.7. Also notice I use a namespaced event to prevent destroying other <code>click</code> events that already attached.

<pre><code>$.fn.sharePop = function(selector) {
 if (typeof OpenPopUpPage == 'function'){
 if (typeof selector === 'string') {
 $(document).off('click.openpopup').on('click.openpopup', selector, function (e) {
 e.preventDefault()
 var href = $(this.attr('href'))

 if (href) {
 OpenPopUpPage($(this).attr('href'))
 }
 })
 } else {
 // attach the event like you already did?
 }

 return this
 }

 return false
};
</code></pre>

Actually , I'd never create plugin thingy like this <code>$.fn.sharePop</code> if I won't share method/API like <code>$('.dialog-pop').sharePop('refresh')</code> or <code>$('.dialog-pop').sharePop('destroy')</code> or whatsoever rather than just bind the event on document ready directly.

Similar to this :
<a href="https://stackoverflow.com/questions/203198/event-binding-on-dynamically-created-elements">Event binding on dynamically created elements?</a>

but I'm not adding an element dynamically only a class to an element using .addClass.

Basic html:

<pre><code>&lt;div id="WebPartWPQ6_ChromeTitle"&gt;
&lt;a accesskey="W" href="/siteurl" &gt;
&lt;span&gt;Access &lt;/span&gt;&lt;/a&gt;&lt;/div&gt;
</code></pre>

Function:

<pre><code>(function($){
$.fn.sharePop = function(){
if(typeof OpenPopUpPage == 'function'){
 return this.each(function(i){
 if($(this).attr('href') != null){
 $(this).click(function(e){
 e.preventDefault();
 OpenPopUpPage($(this).attr('href'));
 });
 }
 });
}
else{
 return false;
}
};
})(jQuery);
$(document).ready(function(){
$('.dialog-pop').sharePop();
 });
</code></pre>

To add class:

<pre><code>$( document ).ready(function() {
 $( "#WebPartWPQ6_ChromeTitle a" ).addClass( "dialog-pop" );
});
</code></pre>

The class gets added fine. But my assumption is it isn't there when the event gets attached to the element - and this line needs to change:

<pre><code>$(this).click(function(e){
</code></pre>

I tried this:

<pre><code>$(this).on('click', '.dialog-pop', function(e){
</code></pre>

But no luck.
