Sapui5 未从JSON模型加载的简单OpenUI5表
尝试一些简单的例子来展示在以我的方式调用MII查询和事务数据之前，JSON模型中的数据 我正在运行MII v15.1.1.8，所以SAPUI5库大约有3年的历史了。为了避免安装NetWeaver Update等，我只下载了OpenUI5库的最新版本，我正在使用它 我已经成功创建了一个示例页面，其中包含按钮、输入字段和从MII Illuminator查询加载的下拉选择列表。 现在我想在sap.ui.table控件中显示文件中的JSON数据 我复制了OpenUI5开发者网站Grid table | Basic上的示例。 当我启动页面时，我看到的只是标题，但没有行。加载时，我看到旁边有7行复选框和空列，然后它们消失了 在Chrome中使用UI5 Inspector，我看到了这些行，并深入到其中，它们被附加到JSON模型，每个都有一个不同的行，正如预期的那样。如果我改变了可见行的数量，那么闪烁的行的数量也会改变 因此，我觉得模型已正确附加，XML视图虽然简化，但与代码示例类似 我能够从模型向控制台写入特定记录，这是对模型不是问题的另一种确认 作为UI5的新手，我确信它很简单，但我只是被卡住了 这里是涉及的各种文件 irpt是一种特殊的MII扩展，类似于HTMLSapui5 未从JSON模型加载的简单OpenUI5表,sapui5,Sapui5,尝试一些简单的例子来展示在以我的方式调用MII查询和事务数据之前，JSON模型中的数据 我正在运行MII v15.1.1.8，所以SAPUI5库大约有3年的历史了。为了避免安装NetWeaver Update等，我只下载了OpenUI5库的最新版本，我正在使用它 我已经成功创建了一个示例页面，其中包含按钮、输入字段和从MII Illuminator查询加载的下拉选择列表。 现在我想在sap.ui.table控件中显示文件中的JSON数据 我复制了OpenUI5开发者网站Grid table |

您必须在文本绑定中使用模型名称：
这是很难完成的事情。尽量准确地提到你面临的问题，只分享相关代码。谢谢你的建议。我尝试了myModel>line，但仍然没有可见的行。但这是向前迈出的一步，现在我在UI5检查器中看到了正确的行值，如UL01、UL02等。因此，我认为您解决了XML视图中文本元素的绑定语法。现在要弄清楚为什么它不可见，因为数据现在似乎映射正确了？根据文本绑定的建议，我现在看到在Chrome中打开的dev tools加载屏幕时，每行中的实际值都会闪烁。但是所有的行都不可见了，我只看到了表头。你有没有可能在控制器中重置模型值？在flash之后，您可以共享当前的编码和屏幕截图吗？每行的文本控件都绑定到UI5 Inspector中的模型，并且行数与visiblerows属性匹配，因此似乎行存在，并且具有正确的绑定，它们只是不可见。我不知道如何附加一个截图，我知道你添加了一个链接，但在哪里放置图像文件？无论如何，屏幕是白色的，除了表头QC调整。没有其他可见的线条。至于flash之后的编码，我不确定你要的是什么，因为上面已经发布了所有的编码。我能够使用json模型成功地填充一个列表和一个sap.m表，并且意识到绑定错误。我需要包括模型名称，如
