问题描述

我试图想出一个HTML5表单的有效模式。我想允许所有上面&小写字母,空格,数字和符号/ \ @#$%& 。

我尝试了几种不同的格式,但我没有任何运气。



到目前为止我有:

 地址:< input type =textname =Addresssize =25pattern = [a-zA-Z0-9] {2,35}]title =标题required /> 


解决方案

这是我用w3schools测试页建立的一个例子:


$ b

<!DOCTYPE html>< html>< body><<< ; form onsubmit =getElementById('s')。innerHTML = getElementById('i').value; return false;>国家代码:< input id =itype =textname =country_codepattern =([a-zA-Z0-9] | | / | \\ | @ |#| \ $ |%|&)+title =三字母国家代码> < input type =submit>< / form>< p>提交值:< span id =s>

注意:Internet Explorer 9及更早版本或Safari中不支持输入标记的模式属性。

$ b $

您可以使用它在进行自己的测试http://www.w3schools.com/tags/tryit.asp?filename=tryhtml5_input_pattern


I am trying to come up with a valid pattern for an HTML5 form. I would like to allow all upper & lower case letters, spaces, numbers, and the symbols / \ @ # $ % & .

I've tried a couple different formats but I haven't had any luck.

So far I have:

Address: <input type="text" name="Address" size="25"  pattern="[a-zA-Z0-9 ]{2,35}]" title="Title" required/>

解决方案

This is an example I built with w3schools test page:

<!DOCTYPE html>
<html>
<body>

<form onsubmit="getElementById('s').innerHTML=getElementById('i').value;return false;">
  Country code: <input id="i" type="text" name="country_code" pattern="([a-zA-Z0-9]| |/|\\|@|#|\$|%|&)+" title="Three letter country code">
  <input type="submit">
</form>
<p>Submitted value: <span id="s">

Note: The pattern attribute of the input tag is not supported in Internet Explorer 9 and earlier versions, or in Safari.

You can use it to make your own tests at http://www.w3schools.com/tags/tryit.asp?filename=tryhtml5_input_pattern
