When the page is being published, the debugger should open and you can step through the code (assuming you enabled at least one breakpoint).

当页面发布的时候，调试器应当打开而且可以跟踪代码（假定至少设置了一个断点）。

Walk through the code and place your cursor on the marker bar (along the left edge of the editor area) on the line with the suspected code. Double-click to set the breakpoint.

遍历代码，将鼠标放在可疑代码一行的标记栏（在编辑器区域的左侧）上，双击即可设置断点。
