Breakpoint mapping is subject to certain limitations.
断点映射受到一些限制。
If two or more lines contain the same code, and you set a breakpoint on one of those duplicate lines, the breakpoint mapping algorithm might select the wrong duplicate in the client-side file.
如果有两行以上包含相同的程序码,而且您已在其中一个重复行上设定了中断点,则中断点对应演算法可能会在用户端档案中选取到错误的重复行。
