为什么console.log不能在chrome中输出？ [英] why does console.log not output in chrome?

问题描述

最近我读了一个关于console.log做什么的查询，我读了一个答案，尝试使用它，发现尽管答案指出它在谷歌浏览器中输出到控制台，但我试过了，没有输出。

我试过这段代码：

 函数put （p）{
 if（window.console&& window.console.log）{
 console.log（p）; //控制台可用
} else {
 alert（p）; 
} 
} 
  

但是...我没有输出控制台或警报此外，.log是一个Math属性，给出了什么？

解决方案

确保在Developer Tools中的Filter控制台部分设置为全部或日志...

我有类似的经历，我看不到任何我的console.log输出，这是因为控制台设置为只在错误上过滤...所有日志条目都存在 - 它们只是不可见。

奖励标记：您也可以按Ctrl +单击以选择多个过滤器（例如错误+日志）。

Recently I read a query about "What does console.log do" and I read an answer, tried using it and found that despite the answer stating that it outputs to the console in googles browser, I just tried it and I get no output.

I did try this code:

function put(p){
if ( window.console && window.console.log ) {
        console.log(p); // console is available
    }else{
        alert(p);
    }
}

BUT... I get neither console output or alert and furthermore .log is a Math property, what gives with that?

解决方案

Make sure that in the Developer Tools the Filter in the console section is set to All or Logs...

I had a similar experience where I couldn't see any of my console.log output and it was because the console was set to filter on Errors only... All the log entries were there - they just weren't visible.

Bonus marks: you can also Ctrl + Click to select multiple filters (Errors + Logs for example).
