至于下面张贴的html代码,它被链接到一个按钮,以便当按钮被点击时,它设置showVisOptionsLayout
为真,因此下面张贴的html代码出现。我面临的问题是,当我点击那个按钮时,.ts
代码被调用,并且init()
被调用“如下面所示”,导致复选框被初始化。我想要实现的是,以保持复选框的状态,即使init()
被调用。换句话说,让我们考虑以下情况:
1-用户点击按钮附加belwo posted html
代码
2-将调用init()
方法
3-因此,将取消选中所有复选框
4-用户选择选中第一个复选框“iVisualizationOperationPasser.areaOfCoverage”
5-作为步骤4的结果,复选框将被选中,菜单将消失“它将消失,因为我这样设计它”
6-当用户再次点击附在下面的'html'上的按钮时,init()
方法将被调用,并且所有复选框将被取消选中。因此,复选框iVisualizationOperationPasser.areaOfCoverage
被设置为真的最新状态将丢失。
我想保持复选框的最新状态,即使下面粘贴的html
的按钮被调用。我想实现复选框可以被取消选中,只有当用户选择这样做时
请让我知道即使init()
被调用几次,如何保持复选框的最新状态
注
for each clikc on the button attached to the below posted `html`, once `showVisOptionsLayout` will be `true causing `init()` to be invoked, and when it is clicked again it will cause `showVisOptionsLayout` to be set to `false`,hence all the check-boxes will be set
to false.
each time the button is clicked, it toggles that state of `showVisOptionsLayout`
