javascript - Function constructor browser support

Question

I would like to know if the Function constructor is supported down to IE7 (MDN says "?").

It seems to be working in IE10 using IE7 mode, but I can't install a native IE7 version since I'm on windows 7.

To anyone whos intrested in the use case:

// expressionFromServer example: 'x.foo < 3 && x.bar != 5'

var filteredRows = 
    $.grep(availableActivityRows, new Function('x', 'return ' + 
                                                    expressionFromServer + ';'));

Answer 2

new Function构造函数的操作在ECMAScript 第一版中指定，并由所有支持任何级别 JS 的浏览器实现。
