How to validate textbox for US formatted Phone No: or Mobile No: via javascript in asp

推荐答案

使用JavaScript验证内容并不是一个好主意（在客户端）。如果有人在浏览器中禁用JavaScript，则您不再验证电话号码。总是在服务器端验证内容！ 一些关于服务器端验证的文章： msdn.microsoft/en-us/library/debza5t0%28v=vs.100%29.aspx [ ^ ] msdn.microsoft/en-us/library/ms972961 .aspx [ ^ ] msdn.microsoft/en-us/library/ aa479013.aspx [ ^ ] 如果你真的想在客户端验证，那么你可以使用正则表达式： developer.mozilla/en-US/docs/Web/JavaScript / Guide / Regular_Expressions [ ^ ] 但正如我之前所说，这是一个坏主意：如果有人在浏览器中禁用了JavaScript，那么电话号码就不会被验证。 Hi, It's not a good idea to validate stuff using JavaScript (at client-side). If someone disables JavaScript in his browser, the you don't longer validate the phone number. ALWAYS validate stuff at server-side! Some articles about server-side validation: msdn.microsoft/en-us/library/debza5t0%28v=vs.100%29.aspx[^] msdn.microsoft/en-us/library/ms972961.aspx[^] msdn.microsoft/en-us/library/aa479013.aspx[^] If you really want to validate at client-side, then you can use a regular expression: developer.mozilla/en-US/docs/Web/JavaScript/Guide/Regular_Expressions[^] But as I said earlier, it's a bad idea: if someone disables JavaScript in his browser, then the phone number isn't validated.
