我想构建一个弹出模式编辑表单,以更改动态表格中的各个表值。现在,使用功能editToggle(i)在单击按钮时出现输入字段。最多不会出现4个输入字段,因为它们用于编辑我的数据模型中的4个值。但是,输入字段(和值)是使用* ngFor动态生成的。我需要一些方法来将这些输入字段传递/复制到我的模式中,以便在那里进行编辑,而不是在网格本身上(单击编辑按钮后当前显示在网格上)。
我尝试使用[[ngModel)]进行克隆,但是它不起作用。我试图使用函数传递它们,但是值返回null。因为HTML仅显示一个输入字段(因为它们是使用* ngFor动态创建的),所以我不知道一种单独传递值的方法。

答案 0 :(得分:0)
您可以设置一个名为selectedRowData
的变量,并在用户单击编辑按钮时将提供程序设置为其值。可以将模式上输入的value
属性设置为所选行的属性。没有组件代码很难说出其他方法的功能,所以我做了一些假设。让我知道您是否还有其他疑问。
这是指向StackBlitz的链接。
编辑
数据仅通过[value]
属性进行绑定,并且没有像跟踪Reactive Forms这样的表单对象跟踪所有更改,因此应首先创建模型
我注释掉了原始解决方案,并在下面添加了更新。 selectedRowData
变量由具有空属性的provider
对象实例化。模态已更新为使用[(ngModel)]
的双向绑定。 StackBlitz也已更新。
当用户在表单中输入其编辑内容时,表将更新。除非需要将数据保留在某处,否则不需要使用保存按钮。
检查Angular Forms Documentation,它应该有助于如何在组件之间传递表单数据。您在此处创建的内容类似于Template-driven Forms。
组件
// selectedRowData = null;
selectedRowData = {
AppID: "",
ClientName: "",
apiKey: "",
Version: "",
protectedsecret: ""
};
editToggle(rowData) {
this.selectedRowData = rowData;
}
