window.open target _self v window.location.href?
Solution 1:
Definitely the second method is preferred because you don't have the overhead of another function invocation:
window.location.href = "webpage.htm";
Solution 2:
Hopefully someone else is saved by reading this.
We encountered an issue with webkit based browsers doing:
window.open("webpage.htm", "_self");
The browser would lockup and die if we had too many DOM nodes. When we switched our code to following the accepted answer of:
location.href = "webpage.html";
all was good. It took us awhile to figure out what was causing the issue, since it wasn't obvious what made our page periodically fail to load.
Solution 3:
As others have said, the second approach is usually preferred.
The two code snippets are not exactly equivalent however: the first one actually sets window.opener
to the window object itself, whereas the second will leave it as it is, at least under Firefox.
