二、后端检查案例

三、vue专项检查案例
http://www.datouwang.com/jiaoben/973.html
主要代码：
/* DaTouWang URL: www.datouwang.com */
var app = new Vue({
el: "#app",
data: {
password: null,
password_length: 0,
typed: false,
contains_lovercase: false,
contains_number: false,
contains_uppercase: false,
valid_password_length: false,
valid_password: false
},
methods: {
p_len: function() {
this.password_length = this.password.length;
if (this.password_length > 7) {
this.valid_password_length = true;
} else {
this.valid_password_length = false;
}
if (this.password_length > 0) {
this.typed = true;
} else {
this.typed = false;
}
this.contains_lovercase = /[a-z]/.test(this.password);
this.contains_number = /\d/.test(this.password);
this.contains_uppercase = /[A-Z]/.test(this.password);
// Check if the password is valid
if (this.contains_lovercase == true && this.contains_number == true) {
this.valid_password = false;
if (
this.contains_uppercase == true &&
this.valid_password_length == true
)
this.valid_password = true;
} else {
this.valid_password = false;
}
}
}
});
四、vue实际应用：
<style lang="css" scoped>
#tips{float: left; font-size: 12px; width: 400px; height: 25px; margin: 4px 0 0 20px;}
#tips span{float: left; width: 40px; height: 20px; color: #fff; overflow:hidden; margin-right: 10px; background: #D7D9DD; line-height:20px; text-align: center; }
#tips .s1{background: #F45A68;}/*红色*/
#tips .s2{background: #fc0;}/*橙色*/
#tips .s3{background: #cc0;}/*黄色*/
#tips .s4{background: #14B12F;}/*绿色*/
</style>
