javascript：console.log在这种情况下不工作？

问题描述：

(function( $ ){ $.fn.openlayers = function( mapElementId, options ) {
        alert(console.log);
        console.log(options);
        ...
    }
});

我试图扩展javascript库中的功能，但很多我的惊喜，当我开始时意识到 console.log 没有记录任何内容。我知道代码正在执行，因为 alert（）正确射击。但是，来自alert函数的返回响应似乎是function（）{}，这是正确的吗？或者实际上是console.log和空函数？

Im trying to extend functionality in a javascript library, but much to my suprise, when i got started i realized that nothing was being logged by console.log.. I know that the code is being executed due to the alert() firing properly. However the returned response from the alert function seems to be "function(){}", is that correct? or is in fact console.log and empty function?

所以这里有什么线索，以及为什么console.log不能正常工作？

So any clues on what's going on here, and why console.log isn't working?

我想我可能找到了罪魁祸首。我正在使用OpenLayers javascript文件，我可以看到他们的库设置

I think i might have found the culprit. Im working with a OpenLayers javascript file, and i can see that their library sets

OpenLayers.Console={log:function(){},...

然而，这是大写的控制台，但也许这不是区别？我也必须在OpenLayers范围内，我无法真正看到我。所以我仍然有点困惑。但它可以解释为什么我看到一个空函数

However, this is uppercase Console, but maybe that doesn't make a difference? I also have to be in the OpenLayers scope, which i can't really see that i am. So i'm still a little baffled. But it would explain why i'm seeing an empty function

这是我从输入console得到的输出加载发生此错误的应用程序后的chrome调试窗口。

This is the output i get from typing "console" in the debug window of chrome after loading the application where this error occurs.

assert: function (){}
count: function (){}
debug: function (){}
dir: function (){}
dirxml: function (){}
error: function (){}
group: function (){}
groupEnd: function (){}
info: function (){}
log: function (){}
profile: function (){}
profileEnd: function (){}
time: function (){}
timeEnd: function (){}
trace: function (){}
warn: function (){}
__proto__: Object

所以看起来似乎那个东西，可能是openlayers javascript覆盖了原生控制台。

So it would seem that something, possibly the openlayers javascript is overriding the native console.

答

在之前添加以下行 OpenLayer脚本告诉它不要覆盖控制台功能。

Add the following line before OpenLayer script to tell it not to override the console functions.

<script type="text/javascript">
    console.firebug=true;
</script>
