Internet Explorer: jquery

Question

我有一个在chrome中工作的简单函数，但在Internet explorer (9)中它崩溃了：

function go() {
    var selector = "span";
    console.log($);
    answer = $(selector); // errors on this line.
    return answer;
}

以下哪项输出：

LOG: function(a,b){return new e.fn.init(a,b,h)} 
SCRIPT438: Object doesn't support this property or method 

所以看起来jQuery就在那里，如果我在IE控制台上运行$("span")，它就能正常工作。所以我很困惑。以前有没有人遇到过这个问题？

仅当调试器打开时，IE才提供console.log函数。卸下console.log($);，它应该可以正常工作。

或者你可以像这样打补丁：

if (!window.console) {
    (function() {
      var names = ["log", "debug", "info", "warn", "error", "assert", "dir", "dirxml",
      "group", "groupEnd", "time", "timeEnd", "count", "trace", "profile", "profileEnd"];
      window.console = {};
      for (var i = 0; i < names.length; ++i) {
        window.console[names[i]] = function() {};
      }
    }());
}
