我正在尝试使用this(页面底部的那个)RegExp来使用jquery验证插件验证电子邮件地址。
这是我的代码:
$.validator.addMethod("email_address", function(value, element, param) {
var email_regexp = new RegExp("[a-z0-9!#$%&'*+/=?^_{|}~-]+(?:\.[a-z0-9!#$%&'*+/=?^_{|}~-]+)*@(?:a-z0-9?.)+(?:[A-Z]{2}|com|org|net|edu|gov|mil|biz|info|mobi|name|aero|asia|jobs|museum)\b", "g");
var result = value.match(email_regexp);
return result ? result.length >= param : false;
}, "Invalid email address");
没有显示JS错误,仍然无法验证任何内容!一直在玩它一个小时,不能让这个工作!
有什么不对吗?
编辑:我还尝试使用//
分隔符:
$.validator.addMethod("email_address", function(value, element, param) {
var result = value.match(/[a-z0-9!#$%&'*+/=?^_{|}~-]+(?:\.[a-z0-9!#$%&'*+/=?^_{|}~-]+)*@(?:a-z0-9?.)+(?:[A-Z]{2}|com|org|net|edu|gov|mil|biz|info|mobi|name|aero|asia|jobs|museum)\b/g);
return result ? result.length >= param : false;
}, "Invalid email address");

~-]+(?:\.[a-z0-9!#$
// ^^
\.
需要再次转义Javascript字符串:
~-]+(?:\\.[a-z0-9!#$
// ^^^
或者,最好使用//
分隔符,而不是从字符串构造RegExp
对象。

为什么在内置email
规则时为jQuery Validate插件编写自定义正则表达式函数?
http://docs.jquery.com/Plugins/Validation/Methods/email
<强> jQuery的:强>
$(document).ready(function() {
$('#myform').validate({
rules: {
field: {
required: true,
email: true
}
}
});
});
<强> HTML:强>
<form id="myform">
<input type="text" name="field" /> <br/>
<input type="submit" />
</form>
工作演示:
.validate()
插件中使用的默认正则表达式函数,仅供参考:
email: function(value, element) {
