在 controller.js 中找不到名称“jQuery"错误 [英] Cannot find name 'jQuery' error in controller.js

问题描述

我正在 VS Code 中开发 UI5 应用程序.我在 *.controller.js 文件中添加了一个新的计数函数，为了显示来自服务器的计数，我在下面的代码中使用了 jQuery:

jQuery.each(this._mFilters, function (sFilterKey, oFilter) {oModel.read("/portfolios/$count", {过滤器:o过滤器，成功:功能(oData){var sPath = "/";+ sFilterKey;oViewModel.setProperty(sPath, oData);}});});

不幸的是，我收到以下错误:

有谁知道为什么会触发错误以及如何修复它?
非常感谢任何帮助或建议.

解决方案

我假设 this._mFilters 是一个对象.在这种情况下，请尝试:

Object.keys(this._mFilters).map(sFilterKey => {const oFilter = this._mFilters[sFilterKey];oModel.read("/portfolios/$count", {过滤器:[oFilter]，成功:函数(sCount){const sPath = `/${sFilterKey}`;oViewModel.setProperty(sPath, +sCount);},});});

还有参数 filters 等待一个数组而不是单个 Filter 实例.>

如果仍然首选 jQuery，请包含 sap/ui/thirdparty/jquery"(以前是 jquery.sap.global") 到控制器的依赖列表.

sap.ui.define([sap/ui/core/mvc/Controller"，//...,sap/ui/第三方/jquery"，], 函数(控制器,/*...,*/jQuery) {//jQuery 在这里可用});

I am developing a UI5 app in VS Code. I added a new count function to the *.controller.js file, and in order to display the count from the server, I am using jQuery like in the following code:

jQuery.each(this._mFilters, function (sFilterKey, oFilter) {
  oModel.read("/portfolios/$count", {
    filters: oFilter,
    success: function (oData) {
      var sPath = "/" + sFilterKey;
      oViewModel.setProperty(sPath, oData);
    }
  });
});

Unfortunately, I get the following error:

Does anyone know why was the error triggered and how it can be fixed?
Any help or suggestion is much appreciated.

解决方案

I assume this._mFilters is an object. In that case, try with:

Object.keys(this._mFilters).map(sFilterKey => {
  const oFilter = this._mFilters[sFilterKey];
  oModel.read("/portfolios/$count", {
    filters: [ oFilter ],
    success: function(sCount) {
      const sPath = `/${sFilterKey}`;
      oViewModel.setProperty(sPath, +sCount);
    },
  });
});

Also the parameter filters awaits an array instead of a single Filter instance.

If jQuery is still preferred, include "sap/ui/thirdparty/jquery" (formerly "jquery.sap.global") to the dependency list of the controller.

sap.ui.define([
  "sap/ui/core/mvc/Controller",
  // ...,
  "sap/ui/thirdparty/jquery",
], function(Controller,/*...,*/ jQuery) {
  // jQuery is here available
});
