Try jQuery <a href="https://api.jquery.com/jQuery.each/">each()</a>

<pre><code> $('input[type=text]').each(function(){
 var text_value=$(this).val();
 if(text_value!='')
 {
 console.log('Value exist');
 }

 })
</code></pre>

blocks|key|143615|text|你可以像下面这样做：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|143616|if+($("#reference,#pin,#fName,#mName,#datepicker").filter(function()+{+return+$(this).val();+}).length+>+0)+{
++//..
}|code-block|syntax|javascript|143617|使用如下所示的通用函数将使其可重用：|143618|function+hasValue(elem)+{
++++return+$(elem).filter(function()+{+return+$(this).val();+}).length+>+0;
}|143619|你可以这样叫它：|143620|hasValue("#my-input-id");|143621|entityMap^0|0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|Q|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|R|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|S|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|T|8|@]|9|@]|A|$E|F]]|$1|K|3|L|5|6|7|U|8|@]|9|@]|A|$]]|$1|M|3|N|5|D|7|V|8|@]|9|@]|A|$E|F]]|$1|O|3|-4|5|6|7|W|8|@]|9|@]|A|$]]]|P|$]]

You could do like below:

<pre><code>if ($("#reference,#pin,#fName,#mName,#datepicker").filter(function() { return $(this).val(); }).length &gt; 0) {
 //..
}
</code></pre>

Using a common function like the following would make it reusable:

<pre><code>function hasValue(elem) {
 return $(elem).filter(function() { return $(this).val(); }).length &gt; 0;
}
</code></pre>

And you could call it like this:

<pre><code>hasValue("#my-input-id");
</code></pre>

Another example: <a href="http://jsfiddle.net/lollero/rr2ss/12/" rel="nofollow">http://jsfiddle.net/lollero/rr2ss/12/</a>

<pre><code>$(function() {

 // Which you can of course change to be more specific, like: $('#myForm input')
 $( "input" ).val(function( i, val ) {

 // Return the console log IF value is not empty
 // value=" " still counts as "not empty", because technically it isn't
 // You could of course replace the console.log(); with anything you'd like
 val &amp;&amp; console.log('not empty: input-' + (++i) );

 // Note that you don't have to return val if you don't want to, it's just for show in this case.
 return val

blocks|key|143650|text|只需使用以下命令：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|143651|if+(!$("#id").val().length+==+0))|code-block|syntax|javascript|143652|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

Just use this:

<pre><code>if (!$("#id").val().length == 0))
</code></pre>

I want to ask if there's a better way in jQuery to select multiple text input then check if any of them has a value. Here's my code: 

<pre><code>if ($("#reference").val() != "" || $("#pin").val() != "" || $("#fName").val() != "" || $("#mName").val() != "" || $("#datepicker").val() != "") { /*logic goes here */ }
</code></pre>

jQuery check if any text input has value

jQuery

我想问一下，在jQuery中是否有更好的方法来选择多个文本输入，然后检查其中是否有值。下面是我的代码：if ($("#reference").val() != "" || $("#pin").val() != "" || $("#fName").val() != "" || $("#mName").val() != "...
