我对jQuery很新,我编写了一个简单的函数来检查每个按键的密码强度。
这个想法是,每次用户输入一个角色时,都会对内容进行评估,以测试他们输入的密码的强度......我相信每个人之前都已经看过这些内容。
无论如何,我使用的逻辑是没有密码以值1开头。当使用小写字符时,分数增加到2.当使用数字时,分数再次递增1,同样为当使用大写字符并且密码长度为5个或更多字符时。
返回的是密码的强度,每次按下一个键时,值为1到5。
所以,关于我的问题。我这样做的方式似乎并不像jQuery那样...几乎就像我可能刚刚完成了直接的javascript。我也想知道我的逻辑。我做过什么或忽略了什么吗?聪明人比我自己的任何建议?
任何建议或意见都将不胜感激。
$(document).ready(function(){
$("#pass_strength").keyup(function() {
var strength = 1;
/*length 5 characters or more*/
if(this.value.length >= 5) {
strength++;
}
/*contains lowercase characters*/
if(this.value.match(/[a-z]+/)) {
strength++;
}
/*contains digits*/
if(this.value.match(/[0-9]+/)) {
strength++;
}
/*contains uppercase characters*/
if(this.value.match(/[A-Z]+/)) {
strength++;
}
alert(strength);
});
});

最好的方法是采用TJB建议的现有插件。
至于你关于代码本身的问题,一个更好的方法就是这样写:
var pass = "f00Bar!";
var strength = 1;
var arr = [/.{5,}/, /[a-z]+/, /[0-9]+/, /[A-Z]+/];
jQuery.map(arr, function(regexp) {
if(pass.match(regexp))
strength++;
});
(已修改以纠正语法错误。)

我建议评估现有的jQuery密码强度插件。 (除非你只是把它作为一种练习)
以下是我发现的一些链接:

除了gs的答案之外,你应该根据常见的字典单词检查密码(可能使用哈希)。否则,您的逻辑会将像“Yellow1”这样的弱密码评估为强。

以上代码段将计算密码长度为6到18个字符的密码强度。每个唯一字符的默认值为
如果在密码中重复一个字符,则每次重复都会丢失2个点。

var passLength = passWord.length;
var specialFlag = 0;
var numberFlag = 0;
var numberGenerator = 0;
var total = 0;
if(/^[a-zA-Z0-9- ]*$/.test(passWord) == false) {
specialFlag =20;
}
if(passWord.match(/[0-9]/)) {
numberFlag = 25;
}
if(passLength>4&&passLength<=6){
numberGenerator =25;
}else if(passLength>=7&&passLength<=9){
numberGenerator =35;
}else if(passLength>9){
numberGenerator =55;
}else if(passLength>0&&passLength<=4){
numberGenerator =15;
}else{
numberGenerator =0;
}
total = numberGenerator + specialFlag + numberFlag;
if(total<30){
$('#progressBar').css('background-color','#CCC');
}else if(total<60&&total>=30){
$('#progressBar').css('background-color','#FF6600');
}else if(total>=60&&total<90){

我发现使用密码验证程序插件的设计很好。让我解释一下步骤
这是完整的代码:https://lets-solve.com/jquery-password-validator/
创建HTML文件并放置密码并确认密码字段字段。
加载CSS
加载javascript
初始化插件
var password_validator = new PasswordValidator();
就这样,如果两个密码都不匹配,现在密码匹配器将显示错误消息。
在提交表单/单击按钮时如何比较和验证密码?
var password_validator = new PasswordValidator();
//检查密码条件是否匹配,如果是,则返回true,否则返回false var is_valid = password_validator.is_valid();
//检查两个密码是否匹配 var is_match = password_validator.match_confirm_password();
