JavaScript innerHTML.length替代

Question

Our application loads a huge HTML file in an iframe. I know the size of the content already, so to check the download progress I am using innerHTML.length. Is there any alternative to count the number of characters loaded in an iframe.

EDIT

The HTML file which is loaded in iframe is large(1.5 MB+) and is generated every time compilation process is done. We would like to show the progress bar to users about the download progress and AFAIK in JavaScript there is no way to check download progress of JS (or resource) file(s), so I am using the content length of iframe to show progress bar.

您还可以使用innerText.length ，这不是替代方法，而是另一种实现方法。
