Vue2.0+ElementUI实现查询条件展开和收起功能组件
一、需求
- el-form如果查询条件过多，影响页面的展示效果。
- 查询条件表单是我们系统中非常常见的功能，我们需要把它封装成一个通用的组件，方便在系统开发中提升开发效率。
- 除了在实现基本查询条件的功能上，还需要实现多条件的折叠和展开功能
二、效果图
三、 代码示例
- 封装查询条件表单组件
SearchButton.vue
<template>
<div>
<el-col :span="1.5" class="elrow">
<el-form-item>
<el-button type="primary" icon="el-icon-search" size="mini">查询</el-button>
</el-form-item>
</el-col>
<el-col :span="1.5" class="elrow">
<el-form-item>
<el-button type="primary" icon="el-icon-refresh" size="mini">重置</el-button>
</el-form-item>
</el-col>
<el-col :span="1.5" class="elrow">
<el-form-item>
<el-button type="text" size="mini" @click="closeSearch">
{{ word }}
<i :class="showAll ? 'el-icon-arrow-up ': 'el-icon-arrow-down'" />
</el-button>
</el-form-item>
</el-col>
</div>
</template>
<script>
export default {
props: {
showAll: {
type: Boolean,
defalut: true
}
},
computed: {
word: function() {
if (this.showAll === false) {
// 对文字进行处理
return '展开搜索'
} else {
return '收起搜索'
}
}
},
mounted() {
/**
* 收起搜索
*/
this.$nextTick(function() {
this.closeSearch()
})
},
methods: {
closeSearch() {
// this.showAll = !this.showAll;
this.$emit('closepop')
console.log('子组件的状态：' + this.showAll)
}
}
}
</script>
<style>
</style>
- 使用查询条件表单组件（引入组件即可）
