如何验证电话和手机号码在javascript

JavaScript也支持正则表达式（正则表达式）。我会建议使用作为基地快报的电话号码的正则表达式的例子。他们认为很多像括号，空格或数字组之间的破折号区号，等你需要想想你想要支持:您当地的公约/数字规则国内区号国际电话号码和拨号前缀依此类推。这不是有些人认为的那样简单。彼得[编辑]这里有一个简单的例子使用JavaScript正则表达式codeprelang="javascript"spanclass="code-keyword"var/spanpattern=/^\(\d{spanclass="code-digit"3/span}\)\s*\d{spanclass="code-digit"3/span}(?:-|\s*)\d{spanclass="code-digit"4/span}$/spanclass="code-keyword"if/span(pattern.test(string)){spanclass="code-comment"///spanspanclass="code-comment"stringlookslikeagood(US)phonenumberwithoptionalareacode,spaceordashinthemiddle/span}/pre/code[/编辑]

anvas kuttan:您好，

<script type="text/javascript">

    function onlyNumbers(event) {

        var charCode = e.which || e.keyCode;

        if (charCode > 31 && (charCode < 48 || charCode > 57))

        return true;

    }

</script>

这将只允许在文本
