<template> <div class="inputclass"> <div v-for="(item,index) in list" :key="index"> <input v-model="item.value" type="password" class="inputborder" @keyup="jumpnext($event,index,item.value)" @keydown="replacevalue(index)"> </div> </div> </template>
js:
jumpnext(event, index, val) { if (!/[0-9]/.test(val)) { this.list[index].value = ""; this.$message({ type: 'warning', message: '该密码仅为数字' }) return } let flag = document.getelementsbyclassname("inputborder"), currinput = flag[index], nextinput = flag[index + 1], lastinput = flag[index - 1]; if (event.keycode != 8) { if (index < (this.list.length - 1)) { nextinput.focus(); } else { currinput.blur(); } } else { if (index != 0) { lastinput.focus(); } } if (index == 0) { this.num1 = event.key + '' } else if (index == 1) { this.num2 = event.key + '' } else if (index == 2) { this.num3 = event.key + '' } else if (index == 3) { this.num4 = event.key + '' } else if (index == 4) { this.num5 = event.key + '' } else if (index == 5) { this.num6 = event.key + '' } let str = this.num1 + this.num2 + this.num3 + this.num4 + this.num5 + this.num6 if (str.length == 6) { let params = str setupsvip(params).then(res => { // this.supervipvisible = false }).catch(err => { // this.supervipvisible = false this.$message({ type: 'error', message: '设置超级vip失败' }) }) } }, /*当键盘按下的时候清空原有的数*/ replacevalue(index) { this.list[index].value = ""; }
css:
.inputborder { background: #ffffff; width: 50px; font-size: 50px; height: 50px; margin-left: 0px; margin-right: 0px; text-align: center; border: 1px solid #706969; } .inputclass { margin-top: 31px; display: flex; justify-content: center; }
