vue每日一学：分享手机验证码登录的实例应用。
首先看下验证码的代码：
<template>
<div>
<el-main>
<el-form :model="ruleForm" :rules="rules" ref="ruleForm" label-width="100px" class="demo-ruleForm">
<el-form-item label="手机号" prop="phone">
<el-input v-model="ruleForm.phone" placeholder="请输入手机号" size=""
maxlength="11"></el-input>
</el-form-item>
<el-form-item label="验证码" prop="code">
<el-row :span="24">
<el-col :span="12">
<el-input v-model="ruleForm.code" auto-complete="off" placeholder="请输入验证码" size=""
maxlength="4"
@keyup.enter.native="submitForm('ruleForm')"></el-input>
</el-col>
<el-col :span="12">
<div class="login-code">
<!--验证码组件-->
<el-button @click="getCode()" :class="{'disabled-style':getCodeBtnDisable}"
:disabled="getCodeBtnDisable">{{ codeBtnWord }}
</el-button>
</div>
</el-col>
</el-row>
</el-form-item>
<!--滑动验证组件-->
<Verify></Verify>
<el-form-item>
<el-button type="primary" @click="submitForm('ruleForm')">登录</el-button>
</el-form-item>
</el-form>
</el-main>
</div>
</template>需要用到的vue验证工具类。看代码：
export default {
// 限制只能输入数字(可以输入两位小数点)
limitInputPointNumber(val) {
if (val === 0 || val === "0" || val === "" || val === undefined) {
return "";
} else {

value = val.replace(/[^\d.]/g, ""); // 清除“数字”和“.”以外的字符
value = value.replace(/\.{2,}/g, "."); // 只保留第一个. 清除多余的
value = value
.replace(".", "$#$")
.replace(/\./g, "")
.replace("$#$", ".");
value = value.replace(/^(-)*(\d+)\.(\d\d).*$/, "$1$2.$3"); // 只能输入两个小数
return value;
}
},
handleRouteToArray(route) {
const matchs = route.path.split('/')
matchs.shift()
let newMatch = []
matchs.map((item, i) => {
if (matchs[i - 1]) {
item = newMatch[i - 1] + '/' + item
}
newMatch.push(item)
})
newMatch = newMatch.map(item => {
return `/${item}`
})
return newMatch
},
// 密码长度8位以上，须包含大写、小写、数字、特殊符号中的任意3种

// document.title = "密码符合要求"
return true
} else {

}
}
},
// 密码验证8-30位任意字符
