此方法是放在input框的input事件内的:
this.timeNum = String(this.timeNum).replace(/D/g, '');//过滤到非数字 this.timeNum = parseInt(this.timeNum); if(isNaN(this.timeNum)){ this.timeNum = 0; }
下面是封装的一个组件:
<template> <div class="hb_time_select" :class="cusClass"> <el-input class="origin_input" size="small" v-model="timeNum" :disabled="disabled" @input="timeNumInput" @change="timeNumChange"> </el-input> <el-select class="time_select" size="small" v-model="unit" @change="unitChange" :disabled="disabled" > <el-option label="分钟" value="1"></el-option> <el-option label="小时" value="2"></el-option> <el-option label="天" value="3"></el-option> </el-select> </div> </template> <script> export default { model:{ prop:'value',//双向绑定props中的value,默认也是这个值(需在prop中声明) event:'input',//触发双向绑定的事件input,默认也是这个事件,可以自定义事件(需在method中声明) }, props:{ cusClass:{ //自定义类名 type:String, default:'0,1' }, disabled:false, value:'',//声明一下value,否则初始值为undefined }, watch:{ value:{ handler(newVal){ console.log(newVal,111111111); if(newVal){ let timeArr = newVal.split(","); this.timeNum = timeArr[0]; this.unit = timeArr[1]; }else{ this.timeNum = 0; this.unit = '1'; let value = `${this.timeNum},${this.unit}`; this.$emit('input',String(value)); } }, immediate:true, } }, data(){ return{ timeNum:0, unit:'1' } }, methods:{ timeNumInput(val){ // 时间输入框input事件 this.timeNum = String(this.timeNum).replace(/D/g, '');//过滤到非数字 this.timeNum = parseInt(this.timeNum); if(isNaN(this.timeNum)){ this.timeNum = 0; } let value = `${this.timeNum},${this.unit}`; this.$emit('input',String(value)); }, timeNumChange(){ //时间输入框change事件事件 let value = `${this.timeNum},${this.unit}`; this.$emit("change",value); }, unitChange(val){ //时间单位输入框改变 let value = `${this.timeNum},${this.unit}`; this.$emit('input',String(value)); this.$emit("change",value); } } } </script> <style lang="scss" scoped> .hb_time_select{ width:230px; display: flex; align-items: center; .origin_input{ flex:1; flex-shrink: 0; } .time_select{ width:88px; flex-shrink: 0; } } </style>
