对搜索栏进行自定义，并通过按钮实现折叠搜索栏效果。自定义效果如下：
折叠前：
折叠后：
其实也简单，只要在对应的vue文件中\src\views\admin\sysxxfsjl.vue对template 设置slot-scope="scope"和 slot="search"属性即可自定义搜索栏内容：
<template slot-scope="scope" slot="search">
<el-form ref="form" :model="searchForm" style="width: 830px;margin-left: -10px; display: inline-block;" label-width="100px">
<el-row>
<el-form-item label="主题：">
<el-input v-model="searchForm.xxbt" style="width: 238px;margin-left: -100px" @change="getList()"></el-input>
</el-form-item>
<el-form-item label="发送人：">
<el-cascader
v-model="fsrid"
:options="options"
clearable
style="width: 242px !important;margin-left: -100px"
:props="{ expandTrigger: 'hover' }"
@change="getList()"></el-cascader>
</el-form-item>
</el-row>
<el-row v-show="moreshow">
<el-form-item label="发送时间：">
<el-date-picker
style="width: 238px !important; margin-left: -100px"
v-model="timeSlot"
type="daterange"
align="right"
unlink-panels
format="yyyy-MM-dd HH:mm:ss"
value-format="yyyy-MM-dd HH:mm:ss"
range-separator="至"
start-placeholder="开始日期"
end-placeholder="结束日期"
:picker-options="pickerOptions"
@change="getList()">
</el-date-picker>
</el-form-item>
<el-form-item label="方式：" >
<el-radio-group v-model="searchForm.fsfs" size="small" style="margin-left: -100px" @change="getList()">
<el-radio-button label="4">系统消息</el-radio-button>
<el-radio-button label="1">手机短信</el-radio-button>
<el-radio-button label="3">微信发送</el-radio-button>
</el-radio-group>
</el-form-item>
</el-row>
<el-row v-show="moreshow">
<el-form-item label="阅读状态：">
<el-radio-group v-model="sfyd" size="small" style="margin-left: -100px;width: 238px" @change="getList()">
<el-radio-button label="2">所有</el-radio-button>
<el-radio-button label="1">已读</el-radio-button>
<el-radio-button label="0">未读</el-radio-button>
</el-radio-group>
</el-form-item>
<el-form-item label="是否转待办：">
<el-radio-group v-model="checkList" style="margin-left: -100px" @change="getList()">
<el-radio-button label="1">是</el-radio-button>
<el-radio-button label="0">否</el-radio-button>
</el-radio-group>
</el-form-item>
</el-row>
</el-form>
</template>
搜索按钮 调用的是getList中的方法，给表格赋值数据
getList(page, params) {
this.tableData=[]
if (this.timeSlot && this.timeSlot.length == 2) {//发送时间
this.searchForm.startTime = this.timeSlot[0].replace(/\+/g, ' ')
this.searchForm.endTime = this.timeSlot[1].replace(/\+/g, ' ')
}else {
delete this.searchForm.startTime
delete this.searchForm.endTime
}
if (this.fsrid.length){//发送人
this.searchForm.fsrid = this.fsrid[this.fsrid.length-1]
}else {
delete this.searchForm.fsrid
}
if (this.sfyd.length>0){//是否转待办
if (this.sfyd== 1){
this.searchForm.sfyd = 1
}else if (this.sfyd== 0){
this.searchForm.sfyd = 0
}else {
delete this.searchForm.sfyd
}
}else {
delete this.searchForm.sfyd
}
if (this.checkList!=''){//是否转待办
if (this.checkList== '1'){
this.searchForm.sfdb = 1
}else {
this.searchForm.sfdb = 0
}
}else {
delete this.searchForm.sfdb
}
if (!page) {
page = this.page
}
this.tableLoading = true
fetchList(Object.assign({
current: page.currentPage,
size: page.pageSize
}, params, this.searchForm )).then(response => {
for(var i=0;i<response.data.data.records.length;i++){
response.data.data.records[i].checkbox=[]
if(response.data.data.records[i].sfyd==0){
response.data.data.records[i].checkbox.push(' 未读')
}else{
response.data.data.records[i].checkbox.push(' 已读')
}
if(response.data.data.records[i].sfdb==1){
response.data.data.records[i].checkbox.push(' 待办')
}
if(response.data.data.records[i].sfsc==1){
response.data.data.records[i].checkbox.push(' 收藏')
}
if(response.data.data.records[i].sfhf==1){
response.data.data.records[i].checkbox.push(' 已回')
}
if(response.data.data.records[i].xxfjmc){
response.data.data.records[i].xxfjmc=response.data.data.records[i].xxfjmc.split(',')
}else{
response.data.data.records[i].xxfjmc=[]
}
this.tableData.push(response.data.data.records[i])
}
this.page.total = response.data.data.total
this.tableLoading = false
}).catch(() => {
this.tableLoading=false
})
},
template 设置slot-scope="scope"和 slot="searchMenu"属性即可自定义搜索按钮，加上更多按钮：
<template slot-scope="scope" slot="searchMenu">
<el-button v-if="moreshow" type="success" class="el-button--small" icon="el-icon-caret-top" @click="getmoreshow(1)">隐藏</el-button>
<el-button v-else class="el-button--small" icon="el-icon-caret-bottom" @click="getmoreshow(2)">更多</el-button>
</template>
更多、隐藏按钮调用方法对搜索项进行显隐
getmoreshow(type){
if(type==1){
this.moreshow=false
}else{
this.moreshow=true
}
},
清空按钮 需在avue-crud上增加@search-reset事件。进行清空选项内容并调用this.getList(this.page);
//搜索清空按钮事件
searchReset(){
this.searchForm = {}
this.searchForm.sfyd = ''
if (this.searchForm.sfyd!=''){//是否转待办
if (this.searchForm.sfyd== '1'){
this.searchForm.sfyd = 1
}else {
this.searchForm.sfyd = 0
}
}else {
delete this.searchForm.sfyd
}
this.fsrid = []
this.timeSlot = []
this.checkList = ''
this.sfyd = ''
this.$refs.crud.toggleSelection();
this.getList(this.page);
},
