答案在这里:Decoding jQuery ,

Jim Driscoll found out that for more standards-respecting browsers, you could use eval.call(window,data), but for Chrome and IE, things are a bit different.

Internet Explorer: It seems that IE uses window.execScript(data)

Chrome: eval.call(window,data) breaks on Chrome, but window[ "eval" ].call( window, data) works on Chrome, and as well as other non-IE browsers, this is how the above workarounds based upon.
