我可以在使用JavaScript的现代浏览器中使用或打开“插入”插入符号吗？

Question

I have a situation where I'd prefer the old flashing box caret (instead of the standard flashing line) that erases the character it is currently situated over and replaces it with whatever the user just typed.

In my case, I would like it for

<input type='text' /> 

but even just turning it on anywhere would be great.

I recall it wasn't so easy to turn on in native windows programming, so I'm not expecting much here.

Anyone know how to do it?

Firefox, Safari, and Chrome do not support an insert, over over-write, mode. In IE (only) you can query if it is turned on by the OS via document.queryCommandValue("OverWrite") but there is not a way to set it.

However, it can be mimicked .
