SAPui5 路由传递参数

Question

我正在尝试通过路由作为此链接中的步骤 32 传递参数，(https://sapui5.netweaver.ondemand.com/docs/guide/2366345a94f64ec1a80f9d9ce50a59ef.html) 但它不起作用，我不知道我做错了什么：

列表控制器

        onPressItemDetail: function(evt) {

        var oSource = evt.getSource();
        var oBind = oSource.getBindingContext();
        var sPath = oBind.getPath();

        var oRouter = sap.ui.core.UIComponent.getRouterFor(this);
        oRouter.navTo("changeitem", { path : sPath});

    },

Manifest.json

        "routes": [{
            "pattern": "",
            "name": "first",
            "target": "first"
        }, {
            "pattern": "secondview",
            "name": "second",
            "target": "second"
        }, {
            "pattern": "checkout",
            "name": "checkout",
            "target": "checkout"
        }, {
            "name": "changeitem/{path}",
            "pattern": "changeitem",
            "target": "changeitem"
        }],

更改项目控制器

    onInit: function() {
        var oRouter = sap.ui.core.UIComponent.getRouterFor(this);
        var rChangeItem = oRouter.getRoute("changeitem");
        rChangeItem.attachPatternMatched(this._onObjectMatched, this);
    },

    _onObjectMatched: function (evt) {

        this.getView().bindElement({
            path: "/" + evt.getParameter("arguments").path,
            model: "item"
        });

    },

显示的错误是：Can not navigate to route with name changeitem because the route does not exist..

Answer 1

您已将pattern 分配给路由的name 属性。

应该是：

{
    "name": "changeitem",
    "pattern": "changeitem/{path}",
    "target": "changeitem"
}
