    Hi I have some text in following format,

    683101,
    682303,
    682302,
    682315,
    683581,
    686667,
    682008,
    683572,
    683573,
    682313,
    686672,
    683545 etc....

    Each line break'ed into next line with "Enter". I have nearly 2000 lines of text like this. i want o display the above string to a single line like this.

    683101, 682303, 682302, 682315, 683581, 686667, 682008, 683572, 683573, 682313, 686672, 683545, 686672, 683545 etc..

    I think there is some tweak options in CSS for doing this. Is there a way in JavaScript to do this? Actually it is not a requirement for me, am just curious to know how it is done.

    • Edit:

    In My text editor it looks like this,

    When i try to run it, this is what i get.


    Thats why i want to remove the enter, multiline.......

    • You need to add \ at the end of each line for multi-line strings – Tushar Commented Aug 31, 2015 at 11:06
    • I know adding slash at the end of the line can solve this. i want to know is there any way to do this programatically or why it is not possible. – locknies Commented Aug 31, 2015 at 11:09
    • Because, Javascript's automatic semicolon insertion adds ; at the end of each line, that is causing error. – Tushar Commented Aug 31, 2015 at 11:10

    Reset to default 5

    You can use Regular expression to remove all the linebreaks and replace them using space.

    str = str.replace(/\n/g, ' ');

    Here, \n will match all the line-breaks, and replace them by space

    I have a simple way for this. You can do this without extra code. Just write like this -

    var str = "12345,\
234234,\
234324,\
234324,\
234324,\
234234";

    now just add a slash

    Ok, If you don't want to use the above method then use another plan is -

    take inside an array and after that use the join method

    var str = [12345,
234234,
234324,
234324,
234324,
234234];


str.join(",");

    If we are using ES6, Then we have an elegant way to do this using Backtick -

    var str = `12345,
234234,
234324,
234324,
234324,
234234`;

    Since your data is already ma separated, you can try to add "[" to the beginning and append " ].toString().replace(/\n/g," ") " to the end of your data to get a single line string like this:

    [683101,
682303,
682302,
682315,
683581,
686667,
682008,
683572,
683573,
682313,
686672,
683545].toString().replace(/\\n/g," ")

    then you get: "683101,682303,682302,682315,683581,686667,682008,683572,683573,682313,686672,683545"

    I hope this helps :)

    If all you want is to put those values in one line then, you can set those values as the value of a textarea field. This will allow you to read all those values into a javascript string. Afterward you can apply the regular expression that Tushar suggested.

    See the code segment below: 

    <textarea id="content">
683101,
682303,
682302,
682315,
683581,
686667,
682008,
683572,
683573,
682313,
686672,
683545
</textarea>

    Here is the javascript: 

    var content = $('#content').val();
var content = content.replace(/\n/g, ' ');
console.log(content);
