MoreClass
关联组件:el-element
子组件:传参 data:组件接收的参数默认为[] 其中classifiable等于true的时候默认到该组件 lable: "分类",----------------------------输入框名称(选填) type: "el-select",------------------------输入框类型(el-inpit,el-selec组件没用到但最好必填) enName: "cate_id",------------------------返回值与model双向绑定(必填) placeholder: "请选择机器类型",-------------输入框占位文本(选填) size: "small",----------------------------输入框大小(选填) show: true,-------------------------------是否展示(必填) filterable: true,-------------------------是否可搜索(选填) clearable: true,--------------------------是否可清除(选填) classifiable: true,-----------------------是否分类,使用组件必填(必填) disabled: false,--------------------------是否禁用(选填) loading: false,---------------------------加载效果(选填) options: [],------------------------------输入框下拉的值,父组件调用接口传递 formLabelAlign:组件返回的参数与v-model双向绑定{} disabled:组件是否禁用默认false size:组件大小默认值small width:组件宽度默认450 Title:组件最外层占位文本默认为请选择分类/品牌/型号 子组件:方法 SearchClass:点击查询后直接父组件中打印formLabelAlign的值 ClearInput:父组件绑定ref直接调用子组件ClearInput()方法,然后子组件会给父组件抛出一个resetfrom()方法,在父组件resetfrom()中清空formLabelAlign中的邦定值 父组件:方法 getphonetype():父组件中获取第一条分类数据 SelectChange():选择数据后调用 后面是处理方法其中如果不是同一个接口resetFields中的值需要改变,后续代码也要修改 SelectChange(item) { const resetFields = { cate_id: ["brand_id", "model_id", "color_id", "rom_id"], brand_id: ["model_id", "color_id", "rom_id"], model_id: ["color_id", "rom_id"], };
