根据input输入情况,检验密码的强度,规则如下: | |
1. 纯数字,纯字母为:弱。 | |
2. 数字与字母组合为:中。 | |
3. 数字,字母,特殊字符@#$%^&*_+[]{}组合为:强。 | |
4. 以上长度必为8位以上。 | |
PS: | |
1. 回复时注意加上下面这句话,才会有语法高亮或格式缩进。 | |
```javascript | |
// you code | |
``` | |
2. 粘贴代码时请使用shift+tab,缩进前面的空白。 |

function test (element) {
var elem = typeof element == "string" ? document.getElementById(element) : element;
elem.onchange = function (event) {
var arr = ["弱", "中", "强"]
var val = this.value,
b = 0;
if(val.length < 9){
alert("密码长度8位以上");
return;
}
if(/[0-9]/.test(val)){
b++;
}
if(/[a-zA-Z]/.test(val)){
b++;
}
if(/[@#\$%\^&\*_\+\[\]\{\}]/.test(val)){
b++;
}
alert("强度" + arr[b-1])
}
}
这么写会不会有问题
