如何在向变量添加内容时添加新行

Question

我有这个：

data.data.message = 'User created';
app.successMsg = data.data.message + '...Redirecting';

我想在...Redirecting之前添加一行。我已经尝试了\n，\r，但它们都无法正常工作。我也在这里阅读了一些文章，但他们都告诉他们使用\n和\r，但它并不适合我。我只是学习，请耐心等待。

当我使用'<br />.... Redirecting'时会发生这种情况：

谢谢！

您可以使用Failed building wheel for ecos Running setup.py clean for ecos Failed to build ecos Installing collected packages: dill, multiprocess, ecos, cvxpy, fancyimpute Found existing installation: dill 0.2.5 DEPRECATION: Uninstalling a distutils installed project (dill) has been deprecated and will be removed in a future version. This is due to the fact that uninstalling a distutils project will only partially uninstall the project. Uninstalling dill-0.2.5: Exception: Traceback (most recent call last): File "C:\ProgramData\Anaconda3\lib\shutil.py", line 538, in move os.rename(src, real_dst) PermissionError: [WinError 5] Access is denied: 'c:\\programdata\\anaconda3\\lib\\site-packages\\dill-0.2.5-py3.6.egg-info' -> 'C:\\Users\\Archit\\AppData\\Local\\Temp\\pip-hir5dush-uninstall\\programdata\\anaconda3\\lib\\site-packages\\dill-0.2.5-py3.6.egg-info' During handling of the above exception, another exception occurred: Traceback (most recent call last): File "C:\ProgramData\Anaconda3\lib\site-packages\pip\basecommand.py", line 215, in main status = self.run(options, args) File "C:\ProgramData\Anaconda3\lib\site-packages\pip\commands\install.py", line 342, in run prefix=options.prefix_path, File "C:\ProgramData\Anaconda3\lib\site-packages\pip\req\req_set.py", line 778, in install requirement.uninstall(auto_confirm=True) File "C:\ProgramData\Anaconda3\lib\site-packages\pip\req\req_install.py", line 754, in uninstall paths_to_remove.remove(auto_confirm) File "C:\ProgramData\Anaconda3\lib\site-packages\pip\req\req_uninstall.py", line 115, in remove renames(path, new_path) File "C:\ProgramData\Anaconda3\lib\site-packages\pip\utils\__init__.py", line 267, in renames shutil.move(old, new) File "C:\ProgramData\Anaconda3\lib\shutil.py", line 553, in move os.unlink(src) PermissionError: [WinError 5] Access is denied: 'c:\\programdata\\anaconda3\\lib\\site-packages\\dill-0.2.5-py3.6.egg-info' 标记来获取新行。 除此之外，您可以使用任何块元素（例如div）将其显示到其他行。它实际上将它放在另一个元素中，并且块元素始终以新行呈现，因此数据将转到下一行。然后你也可以将CSS应用到它。

如果您在浏览器中运行它，那么我的猜测是它呈现为HTML。 HTML忽略换行符，并将所有内容放在同一行。因此，您可以将上述文字放在<pre>括号之间，或者在我们需要新行的地方回显<br />。希望有所帮助。
