这是我的street.json文件
{"街道":[
{" id":" 1"," id_region":" 1"," name":" AAA"},
{" id":" 2"," id_region":" 1","名称":" BBB"},
{" id":" 3"," id_region":" 1"," name":" CCC"},
{" id":" 4"," id_region":" 2"," name":" DDD"},
{" id":" 5"," id_region":" 2"," name":" EEE"},
{" id":" 6"," id_region":" 2"," name":" FFF"},]}
基本上,我正在通过控制器中的BindingContext将id_region从region.view.xml发送到street.view.xml。
当我在street.controller.js中捕获到该id_region时,接下来该怎么做才能显示基于id_region的规格列表。
下一个是我在street.controller.js中所做的事情
onInit:函数(){
var oModel = this.getOwnerComponent()。getModel(" streets"); sap.ui.core.UIComponent.getRouterFor(this).getRoute(" StreetsList")。attachPatternMatched(this._onPostMatched,this);
this.oView = this.getView();
this.oRouter = this.getOwnerComponent()。getRouter();
},
_onPostMatched:函数(oEvent){
var oData = this.getOwnerComponent()。getModel(" street");
var oArrey = oData.getProperty("/img/Streets");
var number = oEvent.getParameter(" arguments")。regionId;
for(var i = 0; i 如果(oArrey [i] .id_region ===数字){ var found = i; 休息; } } this.getView()。bindElement({path:"/img/Streets/" + found}); }
您好,尼古拉
您可以按街道在街景视图中绑定列表,然后在获得地区ID后,将按地区ID过滤设置为绑定项。
