方法一：
$(document).ready(function () { var tempStr = "abcdefg我们都是好孩子"; var pattern_char = /[a-zA-Z]/g; var pattern_chin = /[u4e00-u9fa5]/g; var count_char = tempStr.match(pattern_char).length; var count_chin = tempStr.match(pattern_chin).length; alert(count_char + '_' + count_chin);//7-7 });
方法二：
<script type ="text/javascript"> $(document).ready(function(){ $("#TextBox1").blur(function(){ var tem = $("#TextBox1").val(); var jc_shu = /[0-9]/g; var jc_yin = /[a-zA-Z]/g; var count_shu =tem.match(jc_shu).length; var count_yin =tem.match(jc_yin).length; $("#ts1").text(count_shu + "___" + count_yin ); }); }); </script> </head> <body> <form id="form1" runat="server"> <div> <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox> <div id = "ts1"></div> <div id = "ts2"></div> <br /> <div></div> </div> </form> </body>
