javascript - 如何在函数内设置可观察对象？

Question

我正在尝试将可观察量传递给函数。

function toggleContent(switcher) {
  if (switcher == false) {
    alert(switcher); //this shows the value
    switcher(true);  //this creates an error
    switcher = true; //this doesn't do anything
  }
}

this.content = ko.observable(false);
this.registerClick = toggleContent(this.content());

Answer 1

您需要传递可观察值本身，您当前仅传递其值。使用

this.registerClick = toggleContent(this.content);

而不是

this.registerClick = toggleContent(this.content());
