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">

$("#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 );
});
});
