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>
