猿实战12——类目属性之动态绑定
猿实战是一个原创系列文章，通过实战的方式，采用前后端分离的技术结合SpringMVC Spring Mybatis,手把手教你撸一个完整的电商系统，跟着教程走下来，变身猿人找到工作不是问题。更多精彩内容，敬请大家关注公主号猿人工厂，点击猿人养成获取！
上一个章节，猿人君教会了你如何去用树状的办法去展示属性值，今天我们就一起来完成新增类目属性这个方法。
功能概览
在新增类目属性这个功能中，我们可以在输入需要增加的属性后，点击查询，检索需要新增的属性。然后通过勾选的方式，将需要需要新增的属性，勾选到右边列表，点击保存后，完成新增类目属性的功能。
新增类目属性整体前端
新增类目属性，从本质上讲是一个子组件，通过我们上一章节中展示属性库的数据（猿实战11——类目属性绑定之el-tree的使用），然后通过通过动态表单的方式，提供类目属性的动态新增和删除功能。现在将页面整体都给到你。

</script>
<style scoped>
</style>其中有一些你需要特别注意的东西。比如右侧的已经选择的属性列表，是一个动态列表。一般来说我们使用el-table这样的组件来做到它。
关于如何做到勾选左侧展示的属性，到右侧的动态表单中，需要利用之前在el-tree中定义的回调函数。如何获取已选中的数据节点？使用this.$refs.tree.getCheckedNodes()来获取。
页面API的封装
要完成这样一个功能自然离不开调用后端的数据接口，调用后端的api封装我们可以看一下。
export function createMallCategoryProperty(data) {
return request({
url: '/categoryProperty/addMallCategoryPropertyBatch',
method: 'post',
data: data
})
}
export function updateMallCategoryProperty(data) {
return request({
url: '/categoryProperty/updateMallCategoryProperty',
method: 'post',
data: data
})
}
// 新增类目属性获取可以选择的属性
export function fetchForSelect(query) {
return request({
url: '/categoryProperty/findForSelect',
method: 'post',
data: query
})
}后端数据接口封装
后端的实现较为复杂的上一章节已经讲述过了，现在把剩余的Controller层代码给到你。

}还是那句老话，代码要尽量自己去实现，才能有真正的提高，所以猿人君一直会留下一些小尾巴给你，帮助你提升你的技能。相信你已经能够完成新增属性的前提下，修改属性值的事情，应该也难不倒你，就暂且不讲了噢。
