JS
jQuery.validator.addMethod("valid_url", function(value, element) {
if(!/^(https?|ftp):\/\/i.test(val))
val = 'http://'+val; // set both the value
$(elem).val(val); // also update the form element
}

采纳答案by falsetru
Regular expression literals should be surrounded by the delimiters(/). There's no terminating delimiter:
正则表达式文字应该被分隔符( /)包围。没有终止分隔符：
/^(https?|ftp):\/\//i
// ^
For example:
例如：
>> /^(https?|ftp):\/\//i.test('http://stackoverflow.com/')
true
>> /^(https?|ftp):\/\//i.test('telnet://stackoverflow.com/')
false

You can also get this error if you're simply attempting to concatenate a variable that utilizes a regular expression and forget a quotation mark somewhere.
如果您只是尝试连接使用正则表达式的变量并忘记某处的引号，您也可能会收到此错误。
