使用原生input模拟器样式正常，但是真机上 input框溢出

一、问题

二、解决方法

三、总结

tiips:如嫌繁琐，直接移步总结即可！

一、问题

1.使用原生input写了一个搜索框，在模拟器和pc上一切正常。但是打包放到手机上，样式就有问题：这个搜索框的布局是正常的，但是聚焦到input上，就可以看到input明显溢出了！

二、解决方法

1.真是奇怪，我也没有写什么奇怪的东西呀。pc端和移动端的模拟器都是没有问题的。

布局就是简单的flex布局。input 框 flex:1,其余图标自适应。怎么到移动端就有问题呢？

1）代码如下：

<template>
<!-- 搜索组件 --><div :class="['search-wrap', { round: round }]"><template v-if="isCenterStart"><span class="center" @click.stop="clickCenter"><span class="icon left-icon" v-if="leftIcon"><svg-icon :iconClass="leftIcon"></svg-icon></span><span>{{ placeholder }}</span></span></template><template v-else><span class="icon left-icon" v-if="leftIcon"><svg-icon :iconClass="leftIcon"></svg-icon></span><inputv-model="currentValue"class="input-area":placeholder="placeholder"@input="handleInput"@focus="handleFocus"@blur="handleBlur"/><span v-if="currentValue" class="icon right-icon clear-icon" @click.stop="handleClear"><svg-icon :iconClass="'clearInput'"></svg-icon></span><span v-if="rightIcon" :class="['icon', { 'right-icon': rightIcon }]"><svg-icon :iconClass="rightIcon"></svg-icon></span><slot></slot></template></div>
</template>
<script>
import { nextTick } from 'process';
import { defineComponent, onMounted, ref, watch, getCurrentInstance } from 'vue';
//使用的时候需要用v-model
export default defineComponent({props: {//搜索框的值value: {type: String,default: ''},//提示placeholder: {type: String,default: '请输入'},//左图标leftIcon: {type: String,default: 'search'},//右图标rightIcon: {type: String,default: ''},//是否圆角round: {type: Boolean,default: false},//刚开始是否居中isCenter: {type: Boolean,default: false}},components: {},setup(props, { emit, slots }) {const { proxy } = getCurrentInstance();//当前输入的值const currentValue = ref('');onMounted(() => {currentValue.value = props.value;});//输入事件const handleInput = () => {//输入了字符再触发// if (currentValue.value?.trim()) {emit('input', currentValue.value);// }};//清除const handleClear = () => {currentValue.value = '';setCenter();emit('input', currentValue.value);emit('clear');};//聚焦const handleFocus = () => {emit('focus', currentValue.value);};//失焦const handleBlur = () => {setCenter();emit('blur', currentValue.value);};//初始时是否显示在中间const isCenterStart = ref(props.isCenter);const clickCenter = () => {isCenterStart.value = false;nextTick(() => {proxy.$el.querySelector('input')?.focus();});};const setCenter = () => {if (props.isCenter && !currentValue.value) {isCenterStart.value = true;}};watch(() => props.value,(newVal) => {currentValue.value = newVal;});return {currentValue,handleInput,handleClear,handleFocus,handleBlur,clickCenter,isCenterStart};}
});
</script>
<style lang="scss" scoped>
.search-wrap {display: flex;justify-content: space-between;padding: 20px 40px;background: #f1f3f7;border-radius: 18px;align-items: center;.icon {display: flex;align-items: center;justify-content: center;font-size: 48px;}.right-icon {margin-left: 20px;}.clear-icon {font-size: 60px;}.input-area {flex: 1;font-size: 51px;line-height: 69px;margin-left: 36px;border: none;background: none;&::placeholder {color: #acacac;}&:focus-visible {outline: none;}}
}
.round {background: rgba(255, 255, 255, 0.5);border-radius: 54px;
}
.center {width: 100%;display: flex;justify-content: center;color: #acacac;font-size: 51px;line-height: 75px;transition: ease-in-out;span {margin-left: 36px;}
}
</style>

2.只能一个个试试到底哪个样式有问题。

3.发现注释了最外层父盒子的 display:flex，竟然不溢出了。
