How do I create a new line in Javascript?

var i;
for(i=10; i>=0; i= i-1){
   var s;
   for(s=0; s<i; s = s+1){
    document.write("*");
   }
   //i want this to print a new line
   /document.write(?);

}

I am printing a pyramid of stars, I can't开发者_运维百科 get the new line to print.

Use the \n for a newline character.

document.write("\n");

You can also have more than one:

document.write("\n\n\n"); // 3 new lines!  My oh my!

However, if this is rendering to HTML, you will want to use the HTML tag for a newline:

document.write("<br>");

The string Hello\n\nTest in your source will look like this:

Hello!

Test

The string Hello<br><br>Test will look like this in HTML source:

Hello<br><br>Test

The HTML one will render as line breaks for the person viewing the page, the \n just drops the text to the next line in the source (if it's on an HTML page).

how about:

document.write ("<br>");

(assuming you are in an html page, since a line feed alone will only show as a space)

Use a <br> tag to create a line break in the document

document.write("<br>");

Here's a sample fiddle

• http://jsfiddle.net/g6eAF/

Use "\n":

document.write("\n");

Note, it has to be surrounded in double quotes for it to be interpreted as a newline. No it doesn't.

Alternatively, write to an element with the CSS white-space: pre and use \n for newline character.

document.writeln() is what you are looking for or document.write('\n' + 'words') if you are looking for more granularity in when the new line is used

In html page:

document.write("<br>"); 

but if you are in JavaScript file, then this will work as new line:

document.write("\n");

To create a new line, symbol is '\n'

var i;
for(i=10; i>=0; i= i-1){
   var s;
   for(s=0; s<i; s = s+1){
    document.write("*");
   }
   //i want this to print a new line
   document.write('\n');

}

If you are outputting to the page, you'll want to use "<br/>" instead of '/n';

Escape characters in JavaScript

For a string I just write "\n" to give me a new line. For example, typing console.log("First Name: Rex" + "\n" + "Last Name: Blythe"); Will type:

First Name: Rex

Last Name: Blythe

\n --> newline character is not working for inserting a new line.

    str="Hello!!";
    document.write(str);
    document.write("\n");
    document.write(str);

But if we use below code then it works fine and it gives new line.

    document.write(str);
    document.write("<br>");
    document.write(str);

Note:: I tried in Visual Studio Code.

you can also pyramid of stars like this

for (var i = 5; i >= 1; i--) {
     var py = "";
     for (var j = i; j >= 1; j--) {
         py += j;

     }
     console.log(py);
 }

\n dosen't work. Use html tags

document.write("<br>");
document.write("?");

your solution is

var i;
for(i=10; i>=0; i= i-1){
   var s;
   for(s=0; s<i; s = s+1){
    document.write("*");
   }
   //printing new line
   document.write("<br>");
}

Try to write your code between the HTML pre tag.

It's pretty easy actually. :D

To make a new line, you only need to use \n "function". For HTML related-projects, use only <br>, like in actual HTML script. :)

var i;
for(i=10; i>=0; i= i-1){
   var s;
   for(s=0; s<i; s = s+1){
    document.write("*");
   }
   // Here's the change
   document.write('\n');

}

THE OUTPUT

BUT, be careful the output above won't work in some HTML related projects. For that, you need to use <br> - like in HTML :D

If you are using a JavaScript file (.js) then use document.write("\n");. If you are in a html file (.html or . htm) then use document.write("<br/>");.

document.write("\n");

won't work if you're executing it (document.write();) multiple times.

I'll suggest you should go for:

document.write("<br>");

P.S I know people have stated this answer above but didn't find the difference anywhere so :)

You can use below link: New line in javascript

  var i;
for(i=10; i>=0; i= i-1){
   var s;
   for(s=0; s<i; s = s+1){
    document.write("*");
   }
   //i want this to print a new line
   /document.write('<br>');
