当项目不可观察时刷新observableArray [英] Refresh observableArray when items are not observables

问题描述

基本上，我有一个observableArray，每个项目的值都不是可观察的.这意味着当我更改项目值时，observableArray的foreach循环中的UI不会相应更新.

Basically I have an observableArray and the values for each item are not an observable. This means when I change an item value the UI within a foreach loop of the observableArray does not update accordingly.

如果我必须将它们设置为可观察的，这意味着巨大的变化，那么有没有办法我可以手动刷新UI或observableArray foreach?

It means a massive change if I have to set them to observable, so is there a way I can refresh either the UI or observableArray foreach manually?

推荐答案

是的，您可以为数组调用valueHasMutated函数:

Yes, you can call valueHasMutated function for your array:

yourArray.valueHasMutated();

如果首先没有帮助，则可以执行脏"刷新:

If first didn't help you can do 'dirty' refresh:

self.refresh = function(){
    var data = self.array().slice(0);
    self.array([]);
    self.array(data);
};
