console.trace

console 的 trace() 方法向 Web控制台 输出一个堆栈跟踪。

在页面console文档中查看堆栈跟踪的详细介绍和示例。

console.trace( [...any, ...data ]);

...any, ...data 可选

Zero or more objects to be output to console along with the trace. These are assembled and formatted the same way they would be if passed to the console.log() method.

function foo() {
  function bar() {
    console.trace();
  }
  bar();
}

foo();

In the console, the following trace will be displayed:

bar
foo
<anonymous>
