本文实例讲述了jquery密码强度校验的验证代码,分享给大家供大家参考。具体如下:
预想的效果截图如下:

关键代码:

<script>
 
//下面的正则表达式建议各位收藏哦,项目上有可能会用得着
$(function(){  
  $('#pass').blur(function(e) {
    // alert('---------');
     //密码为八位及以上并且字母数字特殊字符三项都包括
     var strongRegex = new RegExp("^(&#63;=.{8,})(&#63;=.*[A-Z])(&#63;=.*[a-z])(&#63;=.*[0-9])(&#63;=.*\\W).*$", "g");
   
   //密码为七位及以上并且字母、数字、特殊字符三项中有两项,强度是中等 
     var mediumRegex = new RegExp("^(&#63;=.{7,})(((&#63;=.*[A-Z])(&#63;=.*[a-z]))|((&#63;=.*[A-Z])(&#63;=.*[0-9]))|((&#63;=.*[a-z])(&#63;=.*[0-9]))).*$", "g");
     var enoughRegex = new RegExp("(&#63;=.{6,}).*", "g");
     if (false == enoughRegex.test($(this).val())) {
         $('#passstrength').html('More Characters');
     } else if (strongRegex.test($(this).val())) {
         $('#passstrength').className = 'ok';
         $('#passstrength').html('Strong!');
     } else if (mediumRegex.test($(this).val())) {
         $('#passstrength').className = 'alert';
         $('#passstrength').html('Medium!');
     } else {
         $('#passstrength').className = 'error';
         $('#passstrength').html('Weak!');
     }
     return true;
  });
}); 
</script> 
         
<input type="password" name="pass" id="pass" /> 
<span id="passstrength"></span>
Copy after login

以上就是jquery判断密码强度校验代码,大家可以应用到自己的项目中,希望大家喜欢。
