小编ana*_*mbs的帖子

我在印度编号系统中显示以下代码.

 var x=125465778;
 var res= x.toString().replace(/\B(?=(\d{3})+(?!\d))/g, ",");

得到这个输出:125,465,778.

我需要这样的输出:12,54,65,778.

请帮我解决这个问题.

我正在遵循django中的教程并获得以下错误.

找到了一些解决方案,但它没有解决我的错误.教程链接就是这个.

我获得的错误如下.在复制问题之前,请帮我解决这个问题.我正在学习python和django服务,所以它会帮助很多.

编辑1:我将附上两者的urls.py,这样有助于识别

在民意调查/ urls.py中

from django.conf.urls import …

我在学习Python之后正在学习PostgreSQL。我关注tutorialspoint.com 网站。

没有问题，直到我创建一个触发器并且它像一个魅力一样工作。

但是当我尝试删除（即删除）触发器时，出现以下错误。

DROP TRIGGER example_trigger;
ERROR:  syntax error at or near ";"
LINE 1: DROP TRIGGER example_trigger;
                                    ^

我不确定为什么会收到此错误。请帮帮我。这是常见的还是我错了？
