在HTML页面中解析后如何在源代码中放入行号? [英] How to put line number in source code after parse in HTML page?

问题描述

我正在使用angular js和mongoDB，在mongoDB中我有一些带\ n的文本，因此每行都基于\ n进入新行，但是我还想为每行添加行号.

I am using angular js and mongoDB, In mongoDB I have some text with \n, So each line comes into the new line based on \n, But I am also want to add line number for each line.

HTML代码

{{sorceText}}

控制器代码

 $scope.sorceText=" ANB+IO:UI+OPO++7866:1111222'\OKP+JJJJ+PP++IOOIO:9989+KKKKKK+II+22:33'
 IIOI+IOIOOI+OOOO:13:1:IA+AA346+4'
 MSG+8'
 LLL+PLPL:MLML+52519950'
 NBK+290818:0000+MJL+LKL+OK+91'
 KWNN+250'
 NFR'
 KK+KK:MMM'"

立即显示:

     ANB+IO:UI+OPO++7866:1111222'\OKP+JJJJ+PP++IOOIO:9989+KKKKKK+II+22:33'
     IIOI+IOIOOI+OOOO:13:1:IA+AA346+4'
     MSG+8'
     LLL+PLPL:MLML+52519950'
     NBK+290818:0000+MJL+LKL+OK+91'
     KWNN+250'
     NFR'
     KK+KK:MMM'

预期，我想添加每行的行号.

Expected I want to be add line number of each line.

1. ANB + IO:UI + OPO ++ 7866:1111222'\ OKP + JJJJ + PP ++ IOOIO:9989 + KKKKKK + II + 22:33'
2. IIOI + IOIOOI + OOOO:13:1:IA + AA346 + 4'
3. MSG + 8'
4. LLL + PLPL:MLML + 52519950'
5. NBK + 290818:0000 + MJL + LKL + OK + 91'
6. KWNN + 250'
7. NFR'
