客户端验证 [英] client side validation

问题描述

我想通过客户端验证手机号码。我已经验证它是移动设备，不应该从国家代码开始，它应该从9,8或7开始。现在我想验证它，以便它不应少于12位数，包括国家代码。我怎么能实现这个目标？任何人都可以建议我一些示例代码？

我的代码如下：

Hi,
I want to validate a mobile no through client side. I have validated it as mobile no should start with country code and it should start with 9,8 or 7. Now i want to validate it so that it should not less than 12 digit including country code. how can i achieve this? can any one suggest me some sample code?
my code looks like this:

var txtPhone = document.getElementById(phoneID); //validating user phone no

     if (txtPhone.value != "") {

         var y = txtPhone.value;
         if (isNaN(y) || y.indexOf(" ") != -1) {
             alert("Invalid Mobile No.");
//             return false;
         }
         if (y.length > 12 || y.length < 12) {
             alert("Mobile No. should be entered with country code");
            // return false;
         }
         if (!(y.charAt(0) == "9" || y.charAt(0) == "8" || y.charAt(0) == "7")) {
             alert("Mobile No. should start with 9,8 or 7 ");
            // return false;
         }

     }

推荐答案

1。利用HTML5验证

1. Take an advantage of HTML5 validation

<input type="tel" name="phone" required=""></input>

2. U.不支持的后备

3.另外还要进行服务器端验证。您使用的语言不太清楚，但任何服务器端语言都有一些验证库。

2. Use the fallback where not supported

3. Always to server side validation in addition. It is not quite clear what language you use, but any server side language has some validation libraries.
