It's got built-in patterns for stuff like URLs and e-mail addresses, and I think you can have it use your own as well.

blocks|key|1459050|text|如果希望根据正则表达式搜索某些元素，可以使用filter函数。例如，假设您想确保在所有输入框中，用户只输入了数字，那么让我们找到所有不匹配的输入并突出显示它们。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1459051|$("input:text")

++++++++return+this.value.match(/[%5E\d]/);
++++})
++++.addClass("inputError")
;|code-block|syntax|javascript|1459052|当然，如果只是像这样，你可以使用表单验证插件，但是这个方法可以应用于你喜欢的任何类型的元素。另一个例子来说明我的意思:查找id与/[a-z]%2B_\d%2B/匹配的所有元素|1459053|$("[id]").filter(function()+{
++++return+this.id.match(/[a-z]%2B_\d%2B/);
});|1459054|entityMap^0|M|6|0|0|1P|2|1S|C|0|0^^$0|@$1|2|3|4|5|6|7|Q|8|@$9|R|A|S|B|C]]|D|@]|E|$]]|$1|F|3|G|5|H|7|T|8|@]|D|@]|E|$I|J]]|$1|K|3|L|5|6|7|U|8|@$9|V|A|W|B|C]|$9|X|A|Y|B|C]]|D|@]|E|$]]|$1|M|3|N|5|H|7|Z|8|@]|D|@]|E|$I|J]]|$1|O|3|-4|5|6|7|10|8|@]|D|@]|E|$]]]|P|$]]

If you wanted to search some elements based on a regex, you can use the <code>filter</code> function. For example, say you wanted to make sure that in all the input boxes, the user has only entered numbers, so let's find all the inputs which don't match and highlight them.

<pre><code>$("input:text")
 .filter(function() {
 return this.value.match(/[^\d]/);
 })
 .addClass("inputError")
;
</code></pre>

Of course if it was just something like this, you could use the form validation plugin, but this method could be applied to any sort of elements you like. Another example to show what I mean: Find all the elements whose <code>id</code> matches <code>/[a-z]+_\d+/</code>

<pre><code>$("[id]").filter(function() {
 return this.id.match(/[a-z]+_\d+/);
});
</code></pre>

blocks|key|1459096|text|我正在使用jQuery和JavaScript，它对我来说工作得很好：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1459097|var+rege+=+/%5E([A-Za-z0-9_\-\.])%2B\@([A-Za-z0-9_\-\.])%2B\.([A-Za-z]{2,4})$/;

I'm using jQuery and JavaScript and it works fine for me:

<pre><code>var rege = /^([A-Za-z0-9_\-\.])+\@([A-Za-z0-9_\-\.])+\.([A-Za-z]{2,4})$/;
if(rege.test($('#uemail').val())){ //do something }
</code></pre>

blocks|key|1458952|text|除非你正在寻找一些特定的东西，否则你已经可以使用带有字符串的正则Javascript进行正则表达式匹配了。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1458953|例如，您可以使用字符串进行匹配，如下所示：|1458954|var+phrase+=+"This+is+a+phrase";
phrase+=+phrase.replace(/is/i,+"is+not");
alert(phrase);|code-block|syntax|javascript|1458955|除了一般的正则表达式匹配之外，您还在寻找其他东西吗？|1458956|entityMap^0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|N|8|@]|9|@]|A|$]]|$1|D|3|E|5|F|7|O|8|@]|9|@]|A|$G|H]]|$1|I|3|J|5|6|7|P|8|@]|9|@]|A|$]]|$1|K|3|-4|5|6|7|Q|8|@]|9|@]|A|$]]]|L|$]]

Unless you're looking for something specific, you can already do Regular Expression matching using regular Javascript with strings.

For example, you can do matching using a string by something like this...

<pre><code>var phrase = "This is a phrase";
phrase = phrase.replace(/is/i, "is not");
alert(phrase);
</code></pre>

Is there something you're looking for other than just Regular Expression matching in general?

that means all that doesnt match regex becomes nothing , i.e. <code>''</code>

Hungry for spaghetti?

In jQuery, is there a function/plugin which I can use to match a given regular expression in a string?

For example, in an email input box, I get an email address, and want to see if it is in the correct format. What jQuery function should I use to see if my validating regular expression matches the input?

I've googled for a solution, but I haven't been able to find anything.

Regular expression field validation in jQuery

jQuery

在jQuery中，有没有一个函数/插件可以用来匹配字符串中给定的正则表达式？例如，在电子邮件输入框中，我得到一个电子邮件地址，并希望查看它的格式是否正确。我应该使用哪个jQuery函数来查看我的验证正则表达式是否与输入匹配？我已经在谷歌上搜索了解决方案，但我什么也找不到。
