so

<pre><code>$.each('span[id^="date_"]',function(){

and

<pre><code>$.each('span[id^="time_"]',function(){

jQuery syntax for attribute ends with:

<pre><code>$('span[id$="_eform"]')
</code></pre>

jQuery syntax for attribute starts with:

<pre><code>$('span[id^="_eform"]')
</code></pre>

jQuery syntax for attribute contains:

<pre><code>$('span[id*="_eform"]')
</code></pre>

From what I understand, you should need to do something like:

<pre><code>$('span[id$="_eform"]')
</code></pre>

Then, with an <code>each</code> method, test if jQuery-object ids are <code>date</code> or <code>time</code>.

<pre><code>var elements = $('span[id$="_eform"]');
elements.each(function() {
 if(this.id.substring(0,5)=='date') {
 // handle dates
 } else if(this.id.substring(0,5)=='time_') {
 // handle times
 }
});
</code></pre>

blocks|key|642805|text|您可以使用各种方法来实现这一点，这些问题中的大多数都在其他答案中列出。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|642806|但是，如果你只有2个元素，为什么不直接用ID来访问它们呢？也许一旦对它们执行了某个操作，您就想对它们做些什么？在这种情况下，这里列出的所有方法都不能使用。|642807|如果您只是想绑定这两个选择器，那么可以使用|642808|$('#date_eform,+#time_eform')...|code-block|syntax|javascript|642809|你所要求的在你的问题的上下文中没有太多的意义。如果你添加了更多的细节，可能会有更好的方法来完成你所要求的。|642810|entityMap^0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|O|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|P|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|Q|8|@]|9|@]|A|$]]|$1|F|3|G|5|H|7|R|8|@]|9|@]|A|$I|J]]|$1|K|3|L|5|6|7|S|8|@]|9|@]|A|$]]|$1|M|3|-4|5|6|7|T|8|@]|9|@]|A|$]]]|N|$]]

You can use a variety of ways to achieve this, most of those questions are listed in the other answers. 

However, if you only have 2 elements, why aren't you just accessing them directly with the ID? Maybe you want to do something to them once an action has been carried out on them? In which case all the methods listed here can't be used. 

If you simply want to bind the two selectors you can just use 

<pre><code>$('#date_eform, #time_eform')...
</code></pre>

What you're asking for doesn't make too much sense in the context of your question. If you add more details, there may be a better way to do what you're asking for.

blocks|key|642845|text|我建议您使用id和class来完成这项任务；这会使它更清晰。示例如下：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|642846|HTML：|642847|<span+id='date'+class='eform'>

I suggest you use <code>id</code> and <code>class</code> for this task; it would make it clearer. Example below:

HTML:

<pre><code>&lt;span id='date' class='eform'&gt;&lt;/span&gt;
&lt;span id='time' class='eform'&gt;&lt;/span&gt;
</code></pre>

JavaScript (using jQuery):

<pre><code>$(".eform").each(function() {
 switch (this.id) {
 case "date":
 // do something
 break;

 case "time":
 // do something
 break;

 default:
 // "id" is not a case
 }
});
</code></pre>

Example here: <a href="http://fiddle.jshell.net/9hcfx/" rel="nofollow">http://fiddle.jshell.net/9hcfx/</a>

actually i have two span with ids like this <code>date_eform</code> and <code>time_eform</code>.

Now i have to get these ids.. and check if the <code>span</code> id starts with <code>date_</code> then i have to perform some logic. and if <code>span</code> id starts with <code>time_</code> then another action.

<pre><code> &lt;span id='date_eform'&gt;&lt;/span&gt;&lt;span id='time_eform'&gt;&lt;/span&gt;
</code></pre>

Please help me in this.
