如何强制视图刷新而不使其从可观察对象自动触发? [英] How to force a view refresh without having it trigger automatically from an observable?
问题描述
注意:主要用于调试和了解KnockoutJS.
Note: this is mostly for debugging and understanding KnockoutJS.
是否有一种方法可以显式地请求Knockout从(已绑定的)视图模型中刷新视图?我正在寻找类似的东西:
Is there a way to explicitly request Knockout to refresh the view from (already bound) view model? I am looking for something like:
ko.refreshView();
我了解这不是Knockout的预期用途,但我仍然想知道是否存在用于调试和学习目的的此类方法.
I understand that this is not an intended use of Knockout, but I still want to know if there is a such method for debugging and learning purposes.
推荐答案
您不能在整个viewModel上调用某些内容,但是在单个可观察对象上,您可以调用myObservable.valueHasMutated()
通知订户应重新评估.正如您所提到的,在KO中通常不需要这样做.
You can't call something on the entire viewModel, but on an individual observable you can call myObservable.valueHasMutated()
to notify subscribers that they should re-evaluate. This is generally not necessary in KO, as you mentioned.
