Regular expressions require .test() when using jQuery
For example, in the code below, when a regular expression is used on a registration page to match the name, it needs to be in English or Chinese and cannot be a number
code
function sub() {
userName = $('#userName').val();
password = $('input[type="password"]')[0].value;
password2 = $('input[type="password"]')[1].value;
name = $('#6').val();
var userName2 = / ^ [a-zA-Z] [a-zA-Z0-9 _] * $ /;
var name2 = /^.{1,10}[^\d]+$/
if (userName2.test(userName[0])) {
}else{
alert('The first letter must be a letter!');
return
}
if (name2.test(name)) {
}else {
alert('Name 2 has 10 digits and no numbers are allowed')
return
}
alert('Registration successful');
setTimeout("location.href='http://www.baidu.com';",1000);
}
