展示参数明细
elementui Tag标签
<el-table-column label="明细" type="expand">
<template slot-scope="scope">
<!-- 循环渲染tag组件 参数明细 -->
<el-tag :key="i" v-for="(item,i) in scope.row.attr_vals" closable @close="handleClose(scope.row,i)">
{{ item }}
</el-tag>
<!-- 输入的文本框 -->

</template>
// 获取分类参数的数据
async getParamsData() {
// 判断是否选中三级分类,如果未选中则重新选中
if (this.selectdKeys.length !== 3) {
this.selectdKeys = []
this.paramsData = []
return
}
// 根据所选分类获取动态参数或者静态属性 三级分类的id
const { data: res } = await this.$http.get(`categories/${this.cateId}/attributes`, {
params: {
sel: this.activeName,
},
})
if (res.meta.status !== 200) {
return this.$message.error('获取参数列表失败')
}
//对参数的明细进行处理:按空格拆分为数组
res.data.forEach(item=>{
item.attr_vals = item.attr_vals ? item.attr_vals.split(',') : []
})
console.log(res.data)
this.paramsData = res.data
},
展示参数明细功能
inputVisible 控制输入框的显示
showInput
// tag 标签 显示文本输入框
inputVisible:false,
<!-- 输入的文本框 -->
<el-input class="input-new-tag" v-if="inputVisible" v-model="inputValue" ref="saveTagInput" size="small" @keyup.enter.native="handleInputConfirm" @blur="handleInputConfirm">
</el-input>
<!-- 添加的按钮i -->
<el-button v-else class="button-new-tag" size="small" @click="showInput">+ New Tag</el-button>
// tag 显示文本输入框
showInput(){
this.inputVisible=true
}
输入框太宽，修改下长度
.input-new-tag{
width: 120px;
}
但是现在会存在一个问题，颜色和尺寸属性应该是独立的互不产生影响才对，但是这里产生了关联（点击按钮颜色和尺寸都会出现输入框，如果输入内存也都会同时输入）
直接在data里面定义下面的属性是不行的
// tag 标签 显示文本输入框
inputVisible:false,
解决方法：可以在后端返回的参数数据里面加上该属性，用以控制文本框的显示和隐藏
//对参数的明细进行处理:按空格拆分为数组
res.data.forEach(item=>{
item.attr_vals = item.attr_vals ? item.attr_vals.split(',') : []
item.inputVisible=false //控制文本框的显示和隐藏
})
这里的v-if 相当于从该行数据中获取该值用以控制
<!-- 输入的文本框 -->
<el-input class="input-new-tag" v-if="scope.row.inputVisible" v-model="scope.row.inputValue" ref="saveTagInput" size="small" @keyup.enter.native="handleInputConfirm" @blur="handleInputConfirm">
这是文本框输入的值
v-model="scope.row.inputValue"
//对参数的明细进行处理:按空格拆分为数组
res.data.forEach(item=>{
item.attr_vals = item.attr_vals ? item.attr_vals.split(',') : []
item.inputVisible=false //控制文本框的显示和隐藏
item.inputValue='' // 文本框输入的值
})
这两步的目的就是让添加参数的按钮输入框互不产生影响
showInput(scope.row) 这里需要拿到参数对象
<!-- 添加的按钮i -->
<el-button v-else class="button-new-tag" size="small" @click="showInput(scope.row)">+ New Tag</el-button>
所以获取到用户输入的参数后先添加到参数明细attr_vals中
row.attr_vals.push(row.inputValue.trim())
// tag 显示文本输入框
showInput(row){
row.inputVisible=true
this.$nextTick(_ => {
// 点击新增按钮后 输入框获取焦点 ref = saveTagInput
this.$refs.saveTagInput.$refs.input.focus();
});
},
// 文本框失去焦点或按下enter 按键
handleInputConfirm(row){
if(row.inputValue.trim()){
row.attr_vals.push(row.inputValue.trim())
// 更新参数的明细
this.updateParamsDetail(row)
}
row.inputVisible=false
},
// 更新参数的明细
async updateParamsDetail(row){
const {data:res} = await this.$http.put(`categories/${this.cateId}/attributes/${row.attr_id}`,{
attr_name:row.attr_name,
attr_sel:row.attr_sel,
attr_vals:row.attr_vals.join(',')
})
if(res.meta.status !== 200){
return this.$message.error('更新参数明细失败')
}
this.$message.success('更新参数明细成功!')
}
这里失去焦点和执行enter会触发两次事件，执行两次
row.inputValue=''
// 文本框失去焦点或按下enter 按键
handleInputConfirm(row){
if(row.inputValue.trim()){
row.attr_vals.push(row.inputValue.trim())
// 更新参数的明细
this.updateParamsDetail(row)
}
row.inputVisible=false
// 执行完一次(enter 或者失去焦点) 清空，这样就不会执行上面的if
row.inputValue=''
},
实现删除参数明细功能
splice 方法 详情
// 监视tag标签的关闭事件,即删除对应的参数明细项
handleClose(){
row.attr_vals.splice(i,1)
// 更新参数的明细
this.updateParamsDetail(row)
},
实现静态属性的更新
<el-table-column label="明细" type="expand">
<template slot-scope="scope">
<!-- 循环渲染tag组件 参数明细 -->
<el-tag :key="i" v-for="(item,i) in scope.row.attr_vals" closable @close="handleClose(scope.row,i)">
{{ item }}
</el-tag>
<!-- 输入的文本框 -->
<el-input class="input-new-tag" v-if="scope.row.inputVisible" v-model="inputValue" ref="saveTagInput" size="small" @keyup.enter.native="handleInputConfirm(scope.row)" @blur="handleInputConfirm(scope.row)">
</el-input>
<!-- 添加的按钮i -->
<el-button v-else class="button-new-tag" size="small" @click="showInput(scope.row)">+ New Tag</el-button>
</template>
</el-table-column>
只需要把动态属性的明细 复制到静态属性即可
