您不要在Chrome控制台中调试。您可以在Chrome调试器中执行调试。如果您在调试器中的断点处停止,您可以使用控制台通过分配来更改任何范围内变量的值。
You don't debug in the Chrome console. You do debug in the Chrome debugger. And if you are stopped at a breakpoint in the debugger, you can use the console to change the value of any in-scope variable by assigning to it.
例如,打开开发工具并运行此代码,阅读注释:
For instance, open dev tools and run this code, reading the comments:
function foo() {
var bar = 42;
// Normally, you don't have to use a hardcoded breakpoint like
// the one that follows, you can set a breakpoint from within the
// debugger just by navigating to the line of code and clicking in
// the left-hand gutter. But in Stack Snippets the easiest way to
// do one is to use the debugger statement:
debugger;
// Now, when stopped on the breakpoint, type this in the console:
// bar = 67;
// ...and press Enter.
// Then hit the arrow button to allow the script to continue
console.log(bar); // ...and this will log 67 instead of 42.
}
foo();
