javascript - ngBindTemplate 和 ngBind 有什么区别？

Question

根据文档:

The ngBind attribute tells Angular to replace the text content of the specified HTML element with the value of a given expression, and to update the text content when the value of that expression changes.

和

The ngBindTemplate directive specifies that the element text content should be replaced with the interpolation of the template in the ngBindTemplate attribute. Unlike ngBind, the ngBindTemplate can contain multiple {{ }} expressions. This directive is needed since some HTML elements (such as TITLE and OPTION) cannot contain SPAN elements.

我的解释是 ngBindTemplate 可以完成 ngBind 所做的一切，甚至更多。那么为什么我们还要有 ngBind 呢？

Answer 1

正如您在 sources 中看到的那样，ngBindTemplate涉及$interpolate服务，其中:

Compiles a string with markup into an interpolation function. This service is used by the HTML $compile service for data binding.
