当浏览器的开发工具中的语句暂停时，如何在该语句之后立即终止执行？ [英] When paused on a statement within the browser's dev tools, how to terminate execution immediately after that statement?

问题描述

假设我有这个功能：

  function test（）{
 
 //语句1 
 
 statement_X; 
 
 //语句2 
 
} 
  

我正在用浏览器的开发工具踩下语句。现在，当我暂停在statement_X时，我想终止函数执行（我不希望执行函数的statement 2部分），就好像statement_X紧随其后一个返回; 语句。

我知道Chrome具有内联脚本编辑功能，所以我可以手动添加return语句在暂停的语句之后，然后按CTRL + S重新执行整个事情，但是我也需要IE的这个功能，所以我希望有一个通用的解决方案。

早期终止执行似乎是一件容易的事情（对于浏览器），所以我期望这些开发工具的功能。

解决方案

我在IE 9中成功测试了这个，所以我在这里作为答案发布：在$ code> statement_X 在脚本调试器中，点击F10，所以 statement_X 仍然执行，然后右键单击封闭函数的最后一行（具有正确卷曲的行括号} 终止函数体），并从下拉菜单中选择设置下一个语句。这将跳过执行，直到函数结束，就好像在 statement_X 之后有一个void return语句。

如果最后还有其他语句一行功能如下面的代码所示，请小心右键单击大括号，以使此技术正常工作。

  function test（）{alert（statement 1）; 
 alert（statement 2）; } function test2（）{alert（statement 3）; } 
  

在内联函数的情况下，有时候可能需要这样做， 。

Let's say I have this function:

function test () {

    // statements 1

    statement_X;

    // statements 2

}

I'm stepping trough the statements with the browser's dev tools. Now, when I'm paused at "statement_X", I would like to terminate the function execution (I don't want the "statements 2" part of the function to be executed), as if the "statement_X" is immediately followed by a return; statement.

I know that Chrome has inline script editing, so I could manually add the return statement after the paused statement and then hit CTRL+S to re-execute the entire thing, but I need this feature for IE too, so I am hoping for a general solution.

Terminating execution early seems like an easy enough thing to do (for the browser), so I expect such a functionality from the dev tools.

解决方案

I tested this successfully in IE 9, so I'm posting it here as an answer: while pausing at statement_X in the script debugger, hit F10 so statement_X is still executed, then right click on the last line of the enclosing function (the line with the right curly bracket } that terminates the function body), and select "Set next statement" from the drop down menu. This will skip execution until the end of the function as if there were a void return statement just after statement_X.

If there are any other statements on the last line of a function as shown in the code below, be careful to right click just on the curly bracket for this technique to work.

function test () { alert("statement 1");
    alert("statement 2"); } function test2 () { alert("statement 3"); }

This may be sometimes necessary in the case of inline functions, or in minified scripts not intended for debugging.
