如何用换行符代替分号？

Question

I want to replace semicolon with new line.
ie whenever semicolon applears it has to move to new line.
I tried .replace() . It was not working for new line but was working for some other string. One more problem is only the first semicolon will be replaced.

Here is my code snippet:

<p>{{X.content.replace(';', '\n')}} </pre>

This was not working, then i tried with:

<p> {{X.content.replace(';', 'REPLACE')}} </p>

The code was working with any other string but only the first semicolon (;) will be replaced.

I want this to be converted and appear in the new line

first line; second line; third line;

Answer 1

You need a regex with global flag to change all instances

X.content.replace(/;/g, '\n')

this is not something you should be doing in the view. Suggest you create a filter or modify the data in controller

Answer 2

try like this here is one working example

var x ="dsdfs;sfsf;fdsfs"
console.log(x)//"dsdfs;sfsf;fdsfs"

var y  =x.replace(/;/g, " \n ")
 console.log(y)
 //"dsdfs 
   sfsf 
   fdsfs"

There are a few different things going wrong for you:

Only thie first semicolon is replaced:

This is the default for JavScript. A regex will replace the rest.

X.content.replace(/;/g, '\n')

The newlines don't show up:

This is because HTML does not respect newlines by default. You seam to have realised this because you have writen <p></pre> (which is odd and broken).

Either:
Replace ; with \\n and then use a well formed pre:

<pre>{{X.content.replace(/;/g, '\n')}}</pre>

Or:
Replace ; with <br /> and then declare the result as html:
(Warning: this option leaves you open to injection attacks so you need to make sure you trust the content)

<p ng-bind-html="X.content.replace(/;/g, '<br />')"></p>

---

EDIT:

Probably a better approach for you would be to forget all that and just do:

<p ng-repeat="line in X.content.split(';')">{{line}}</p>

This is less risky and results in nicer HTML to style as you choose.
