Why not use window->eval() instead of window->execScript in ScriptEngine.cpp

Cause some script is not work in Firefox and Chrome, but only can execute in IE10.

I don't think you're looking at the correct code. There is custom code for each browser for running script and you are likely running into Chrome/Firefox sandbox issues. That said, Chrome should be using the same interface that the dev console uses so if you can run a script there it should work.

Here is the code in the Chrome agent that executes script: https://github.com/WPO-Foundation/webpag...ger.js#L89

Here is the IE code: https://github.com/WPO-Foundation/webpag...pt.cc#L557

Here is the Firefox code: https://github.com/WPO-Foundation/webpag...il.js#L123

Firefox has a pretty restrictive sandbox that I haven't found a way out of from an extension yet but Chrome and IE should both have good page access.
