前端随机生成验证码vuejsvant~element

h5移动端

1.具体实现效果

2.创建SIdentify组件，主要用于验证码样式

<template><div class="s-canvas"><canvas id="s-canvas" :width="contentWidth" :height="contentHeight"></canvas></div>
</template>
<script>export default{name: 'SIdentify',props: {// 生成的验证码identifyCode: {type: String,default: '1234'},// 字体最小值fontSizeMin: {type: Number,default: 20},// 字体最大值fontSizeMax: {type: Number,default: 35},// 背景色最大值backgroundColorMin: {type: Number,default: 180},// 背景色最小值backgroundColorMax: {type: Number,default: 240},// 字颜色最小值colorMin: {type: Number,default: 50},// 字颜色最大值colorMax: {type: Number,default: 160},// 干扰线颜色最小值lineColorMin: {type: Number,default: 40},// 干扰线颜色最大值lineColorMax: {type: Number,default: 180},dotColorMin: {type: Number,default: 0},dotColorMax: {type: Number,default: 255},// 背景宽度contentWidth: {type: Number,default: 112},// 背景高度contentHeight: {type: Number,default: 38}},methods: {// 生成一个随机数randomNum (min, max) {return Math.floor(Math.random() * (max - min) + min)},// 生成一个随机的颜色randomColor (min, max) {let r = this.randomNum(min, max)let g = this.randomNum(min, max)let b = this.randomNum(min, max)return 'rgb(' + r + ',' + g + ',' + b + ')'},drawPic () {let canvas = document.getElementById('s-canvas')let ctx = canvas.getContext('2d')ctx.textBaseline = 'bottom'// 绘制背景ctx.fillStyle = this.randomColor(this.backgroundColorMin, this.backgroundColorMax)ctx.fillRect(0, 0, this.contentWidth, this.contentHeight)// 绘制文字for (let i = 0; i < this.identifyCode.length; i++) {this.drawText(ctx, this.identifyCode[i], i)}this.drawLine(ctx)this.drawDot(ctx)},drawText (ctx, txt, i) {ctx.fillStyle = this.randomColor(this.colorMin, this.colorMax)ctx.font = this.randomNum(this.fontSizeMin, this.fontSizeMax) + 'px SimHei'let x = (i + 1) * (this.contentWidth / (this.identifyCode.length + 1))let y = this.randomNum(this.fontSizeMax, this.contentHeight - 5)var deg = this.randomNum(-45, 45)// 修改坐标原点和旋转角度ctx.translate(x, y)ctx.rotate(deg * Math.PI / 180)ctx.fillText(txt, 0, 0)// 恢复坐标原点和旋转角度ctx.rotate(-deg * Math.PI / 180)ctx.translate(-x, -y)},drawLine (ctx) {// 绘制干扰线for (let i = 0; i < 3; i++) {ctx.strokeStyle = this.randomColor(this.lineColorMin, this.lineColorMax)ctx.beginPath()ctx.moveTo(this.randomNum(0, this.contentWidth), this.randomNum(0, this.contentHeight))ctx.lineTo(this.randomNum(0, this.contentWidth), this.randomNum(0, this.contentHeight))ctx.stroke()}},drawDot (ctx) {// 绘制干扰点for (let i = 0; i < 30; i++) {ctx.fillStyle = this.randomColor(0, 255)ctx.beginPath()ctx.arc(this.randomNum(0, this.contentWidth), this.randomNum(0, this.contentHeight), 1, 0, 2 * Math.PI)ctx.fill()}}},watch: {identifyCode () {this.drawPic()}},mounted () {this.drawPic()}}
</script>

3.在vue文件中使用

  <van-cell-group class="vantCell"><van-field v-model="formData.mobile" label="手机号码" placeholder="请输入手机号码" /><van-field v-model="formData.password" label="账户密码" placeholder="请输入账户密码" /><van-field v-model="formData.code" label="验证码" placeholder="请输入验证码" /><div class="indentfy" @click="changeCode"><s-identify :identifyCode="code" :contentHeight="40"/></div></van-cell-group>

4.在js文件中引用

import SIdentify from './SIdentify'export default {data () {return {formData:{mobile: '',password: '',code:''},code: ''}}components: {SIdentify},methods: {// 获得验证码createCode () { var code = "";var codeLength = 4;//验证码的长度var random = new Array(0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 'a',    'b', 'c', 'd', 'e', 'f', 'g','h', 'i', 'j', 'k', 'l', 'm', 'n', 'o', 'p', 'q', 'r', 's', 't', 'u', 'v', 'w', 'x', 'y', 'z');// 随机数for (var i = 0; i < codeLength; i++) {//循环操作var index = Math.floor(Math.random() * 36);//取得随机数的             索引（0~35）code += random[index];//根据索引取得随机数加到code上}this.code = code},//点击切换验证码changeCode () {this.createCode()},},mounted () {this.changeCode() // 初始化验证码}
}

5.css样式

.vantCell {position: relative;;
}
.indentfy {position: absolute;bottom: 0;right: 10px;height: 40px;vertical-align: top;display: inline-block;cursor: pointer;
}

4.在js文件中引用

import SIdentify from './SIdentify'

}

5.css样式
