主要功能:
- 点击"停顿"按钮切换对话框显示状态
- 输入框聚焦时保持状态
- 点击对话框外的区域自动关闭
以下是代码版本:
vue
<template>
<div class="input-container">
<el-input
v-model="input"
style="width: 240px"
placeholder="Please input"
ref="inputRef"
class="input-ref"
@focus="handleFocus"
/>
<el-button
class="input-btn"
@click.stop="toggleDialog"
:disabled="!isFocused"
:type="showDialog ? 'primary' : ''"
>
停顿 {{ isFocused ? 'ON' : 'OFF' }}
</el-button>
<transition name="fade">
<div v-if="showDialog" class="dialog-wrapper" @click.stop>
<dl class="dialog-content">
<dt>插入内容</dt>
<dd @click="closeDialog" style="cursor: pointer">插入btn</dd>
</dl>
</div>
</transition>
</div>
</template>
<script lang="ts" setup>
import { ref, onMounted, onBeforeUnmount } from "vue";
const showDialog = ref(false);
const input = ref("");
const inputRef = ref<HTMLInputElement>();
const isFocused = ref(false);
const handleDocumentClick = (e: MouseEvent) => {
const target = e.target as HTMLElement;
const clickedInside = target.closest(".input-container");
if (!clickedInside && isFocused.value) {
closeDialog();
}
};
onMounted(() => {
document.addEventListener("click", handleDocumentClick);
});
onBeforeUnmount(() => {
document.removeEventListener("click", handleDocumentClick);
});
function closeDialog() {
showDialog.value = false;
if (inputRef.value) {
inputRef.value.blur();
}
isFocused.value = false;
}
function handleFocus() {
isFocused.value = true;
}
function toggleDialog() {
showDialog.value = !showDialog.value;
if (inputRef.value) {
inputRef.value.focus();
}
}
</script>
<style scoped>
.input-container {
position: relative;
display: inline-block;
}
.dialog-wrapper {
position: absolute;
top: 100%;
left: 0;
margin-top: 8px;
padding: 12px;
background: white;
border: 1px solid #ebeef5;
border-radius: 4px;
box-shadow: 0 2px 12px 0 rgba(0,0,0,0.1);
z-index: 2000;
}
.fade-enter-active, .fade-leave-active {
transition: opacity 0.2s;
}
.fade-enter-from, .fade-leave-to {
opacity: 0;
}
</style>
主要优点:
-
更好的结构:
- 添加了容器元素
.input-container
方便定位 - 使用 transition 实现平滑的对话框动画
- 添加了容器元素
-
安全的实现:
- 添加了类型定义
inputRef.value
为HTMLInputElement
- 使用生命周期钩子管理事件监听
- 添加了点击对话框防止事件冒泡的
@click.stop
- 添加了类型定义
-
用户体验:
- 按钮状态更直观 (添加了 primary 样式)
- 添加了过渡动画
- 对话框样式更美观
-
代码组织:
- 重命名方法更语义化 (
toggleDialog
替代 [pauseInput] - 分离了关闭逻辑到
closeDialog
方法
- 重命名方法更语义化 (
-
DOM 检查优化:
- 使用整个容器检查替代具体元素检查
