我们应该在调用ko.applyBindings之前等待DOM加载吗 [英] Should we wait for DOM to load before calling ko.applyBindings

问题描述

按照标题，是否有必要在调用ko.applyBindings之前等待DOM加载，还是Knockout会自动处理此问题?

As per the title, is it necessary to wait for the DOM to load before calling ko.applyBindings or will Knockout handle this automatically?

即-我可以安全地这样做吗?

I.e - am I safe to just do:

<script>
(function() {

    var model = new my.Model();
    ko.applyBindings(model);

})();
</script>

推荐答案

没有KO无法自动处理此问题(因此，自调用功能仅在页面底部起作用)，您必须等待DOM加载完毕ko.applyBindings调用.

No KO doesn't handle this automatically (so the self invoking function would work only at the bottom your page), you have to wait for the DOM loaded with the ko.applyBindings call.

从文档:

要激活淘汰赛，请将以下行添加到<script>块:

ko.applyBindings(myViewModel);

您可以将脚本块放在 HTML文档的底部，也可以将其放在顶部，然后 将内容包装在支持DOM的处理程序中，例如jQuery的$函数.

You can either put the script block at the bottom of your HTML document, or you can put it at the top and wrap the contents in a DOM-ready handler such as jQuery’s $ function.
