我的密码强度检查器有问题。 结果的颜色不会根据密码的强度而改变。 我想我在javascript中遇到“addClass”问题。 这是代码......

的CSS：

{
width:20%;
background-color:#000;
margin:0 auto;
border:5px solid #FFF;
margin-top:150px;

border: 2px solid rgb(105, 91, 91);
box-shadow: 2px 2px 10px #FFF;
background: #CCC;
}
.input
{
margin:10px;
}
#result
{
color:#F00;
text-shadow:#666;
}
a
{
color:#000;
}
.red{color:red;}
.orange{color:orange;}
.green{color:green;}
JS：
$(document).ready(function() {
$('#password').keyup(function(){
$('#result').html(checkStrength($('#password').val()))
})
function checkStrength(password){
var strength = 0
if (password.length < 6) {
$('#result').removeClass()
$('#result').addClass('short green')
return 'Too short'
}
if (password.length > 7) strength += 1
if (password.match(/([a-z].*[A-Z])|([A-Z].*[a-z])/)) strength += 1
if (password.match(/([a-zA-Z])/) && password.match(/([0-9])/)) strength += 1
if (password.match(/([!,%,&,@,#,$,^,*,?,_,~])/)) strength += 1
if (password.match(/(.*[!,%,&,@,#,$,^,*,?,_,~].*[!,%,&,@,#,$,^,*,?,_,~])/)) strength += 1
if (strength < 2 ) {
$('#result').removeClass()
$('#result').addClass('weak')
$('#result').addClass('green')
return 'Weak'
} else if (strength == 2 ) {

习惯了这个
#result.red{color:red;}
#result.orange{color:orange;}
#result.green{color:green;}
因为您曾经使用ID而不是申请css类，但id比class的权力高于ID以及css的权力$(document).ready(function() {
$('#password').keyup(function(){
$('#result').html(checkStrength($('#password').val()))
})
function checkStrength(password){
var strength = 0
if (password.length < 6) {
$('#result').removeClass()
$('#result').addClass('short green')
return 'Too short'
}
if (password.length > 7) strength += 1
if (password.match(/([a-z].*[A-Z])|([A-Z].*[a-z])/)) strength += 1
if (password.match(/([a-zA-Z])/) && password.match(/([0-9])/)) strength += 1
if (password.match(/([!,%,&,@,#,$,^,*,?,_,~])/)) strength += 1
if (password.match(/(.*[!,%,&,@,#,$,^,*,?,_,~].*[!,%,&,@,#,$,^,*,?,_,~])/)) strength += 1
if (strength < 2 ) {
$('#result').removeClass()
$('#result').addClass('weak');
$('#result').addClass('green');
return 'Weak'
} else if (strength == 2 ) {
$('#result').removeClass('green');
$('#result').addClass('orange');
return 'Good'
} else {
$('#result').removeClass('red');
$('#result').removeClass('orange');
$('#result').addClass('strong green');
return 'Strong'
}
}
});

答案 1 :(得分：0)
您为span元素的id提供了颜色.Id属性的优先级高于class属性，因此颜色不会分配给结果。
您可以将类添加到<span>元素并为该类提供颜色。
您可以在此处查看演示http://jsfiddle.net/tenigada/RH8f6/575/

我发现this它可以帮助您实现使用javascript
function password_validate(txt) {
var val1 = 0;
var val2 = 0;
var val3 = 0;
var val4 = 0;
var val5 = 0;
var counter, color, result;
var flag = false;
if (txt.value.length <= 0) {
counter = 0;
color = "transparent";
result = "";
}
if (txt.value.length < 8 & txt.value.length > 0) {
counter = 20;
color = "red";
result = "Short";
} else {
document.getElementById(txt.id + "error").innerHTML = " ";
txt.style.borderColor = "grey";
var regex = /^(?=.*\d)(?=.*[a-z])(?=.*[A-Z])(?=.*[^a-zA-Z0-9])(?!.*\s).{8,15}$/;
// document.getElementById("pass_veri").style.display="block";
var fletter = /[a-z]/;
if (fletter.test(txt.value)) {
val1 = 20;
} else {
val1 = 0;
}
//macth special character
var special_char = /[-!$%^&*()_+|~=`{}\[\]:";'<>?,.\/]/;
if (special_char.test(txt.value)) {
val2 = 30;
} else {
val = 0;
}
/*capital_letter*/
var cap_lett = /[A-Z]/;
if (cap_lett.test(txt.value)) {
val3 = 20;
} else {
val = 0;
}
/*one numeric*/
var num = /[0-9]/;
if (num.test(txt.value)) {
val4 = 20;
} else {
val4 = 0;
}
/* 8-15 character*/
var range = /^.{8,50}$/;
if (range.test(txt.value)) {
val5 = 10;
} else {
val5 = 0;
}
counter = val1 + val2 + val3 + val4 + val5;
if (counter >= 30) {
color = "skyblue";
result = "Fair";
}
if (counter >= 50) {
color = "gold";
result = "Good";
}
if (counter >= 80) {
color = "green";
result = "Strong";
}
if (counter >= 90) {
color = "green";
result = "Very Strong";
}
}
document.getElementById("prog").style.width = counter + "%";
document.getElementById("prog").style.backgroundColor = color;
document.getElementById("result").innerHTML = result;
document.getElementById("result").style.color = color;
