稍加改造,感觉这个需求有些矛盾,
<template>
<view>
<input type="text" class="input" v-model="inputVal" placeholder="请输入" :focus="focus" :cursor="cursor" :disabled="disabled"
@tap="cursorStart">
</view>
</template>
<script>
export default {
data() {
return {
cursor: 0,
focus: false,
inputVal: '',
disabled:true
}
},
onLoad() {
uni.onKeyboardHeightChange(res => {
if (res.height == 0) { //键盘隐藏
this.focus = false
this.disabled = true
}
})
},
methods: {
cursorFun() { //结束
this.cursorAction(this.inputVal.length)
},
cursorStart() { //开始
this.cursorAction(0)
},
cursorAction(num) { //获得焦点,设置位置
if(!this.disabled){
return
}
this.disabled = false
this.$nextTick(() => {
this.focus = true
this.cursor = num
})
}
}
}
</script>
<style>
.input {
padding: 30rpx;
margin-bottom: 50rpx;
}
</style>

我试了将input的 :curser=“text.length”和 :curser="4"都没用
