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>
      <input
        v-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

    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。
