对于IE8或控制台支持仅限于console.log(没有调试，跟踪，…)，您可以执行以下操作:

如果console或console.log未定义:为 控制台函数(跟踪，调试，日志，…) 窗口。控制台= { Debug: function(){}，…}; 否则，如果console.log被定义(IE8)和console.debug(任何其他)没有定义:重定向所有日志功能到console.log，这允许保留这些日志! 窗口。控制台= { 调试:window.console.log，…};

不确定在各种IE版本中的assert支持，但欢迎任何建议。也在这里发布了这个答案:我如何在Internet Explorer中使用控制台登录?

You can use the below to give an extra degree of insurance that you've got all bases covered. Using typeof first will avoid any undefined errors. Using === will also ensure that the name of the type is actually the string "undefined". Finally, you'll want to add a parameter to the function signature (I chose logMsg arbitrarily) to ensure consistency, since you do pass whatever you want printed to the console to the log function. This also keep you intellisense accurate and avoids any warnings/errors in your JS aware IDE.

if(!window.console || typeof console === "undefined") {
  var console = { log: function (logMsg) { } };
}

您可以在Firefox中直接使用console.log(…)，但不能在ie中使用。在ie中，你必须使用window.console。

有时控制台可以在IE8/9中工作，但在其他时候会失败。这种不稳定的行为取决于你是否打开了开发工具，并在stackoverflow问题中描述了IE9是否支持console.log，这是一个真实的函数吗?

如果你在IE8中打开了开发人员工具，你可以使用Console .log()，也可以使用脚本选项卡上的控制台文本框。

在TypeScript中控制台的存根:

if (!window.console) {
console = {
    assert: () => undefined,
    clear: () => undefined,
    count: () => undefined,
    debug: () => undefined,
    dir: () => undefined,
    dirxml: () => undefined,
    error: () => undefined,
    group: () => undefined,
    groupCollapsed: () => undefined,
    groupEnd: () => undefined,
    info: () => undefined,
    log: () => undefined,
    msIsIndependentlyComposed: (e: Element) => false,
    profile: () => undefined,
    profileEnd: () => undefined,
    select: () => undefined,
    time: () => undefined,
    timeEnd: () => undefined,
    trace: () => undefined,
    warn: () => undefined,
    }
};
