如何更改 javascript 文件的输出格式？

Question

Javascript:

window.onload=function(){
  chrome.runtime.getBackgroundPage(function(backgroundPage){ 
  var currentUrl = backgroundPage.tabURL;

  console.log(currentUrl);



    var xmlHttp = new XMLHttpRequest();
    xmlHttp.open( "GET", 'http://127.0.0.1:5000/post?url=websiteurl.com', false ); 
    xmlHttp.send( null );
    console.log(xmlHttp.responseText);
    document.getElementById('currentUrl').innerHTML = xmlHttp.responseText;
    return xmlHttp.responseText;

 })

};

This code produces an output that looks like:

[Value1],[Value2],[Value3].

How do I change it so the output is formatted like:

  **[Value1],

    [Value2],

    [Value3],**

with one word per line and in bold? I'm sure its really easy, but I don't know how to go about doing it?

HTML:

<div id='currentUrl'>

        <script type="text/javascript" src="popup.js"></script>


        </div>

Answer 1

You should use CSS to make it bold. You can use join() if it's an array or replace() if it's a string to replace the , with ,<br>

Answer 2

First to replace all the dots to commas you can use:

var stringReg= new RegExp(stringtoreplace, '.');
targetstring = targetstring.replace(stringReg, ',');

Then if you want to add new lines within your string you can add:

"This is my string \nThis is a newline"

If you need to loop each element you can just append the newline string to the end of each element. You can loop the string and every time you find a "]," you can add the newline character to the right of it, you can use regex for this:

var stringReg= new RegExp(stringtoreplace, '],');
targetstring = targetstring.replace(stringReg, '],\n');

You can append a string to the front by doing:

var result = str1.concat("**");

Or you could simply do this instead:

var startString = "**"
var endString = "**"
var mainString = "This is the main string"
var newString = startString + mainString + endString

For making it bold, use CSS

I think this is what you are looking for, you can use split() and join() functions to produce the desired output.

 const strgVal = '[Value1],[Value2],[Value3]'; let fromatedSr = '**' + strgVal.split(',').join(',\\n') + '**'; console.log(fromatedSr);
