How to give multiple lines as input to a javascript variable
Question
I wanted to fill a text area with some text as the user presses a button. But I have a problem that the variable to fill the text takes only single line input but I wanted to have some text with multiple lines and indentations
<!DOCTYPE html>
<html>
<head>
<title>SampleCodes</title>
<link rel="stylesheet" type="text/css" href="style.css">
</head>
<body>
<script type="text/javascript">
function fill(){
var text1 ="#include<stdio.h>
#include<conio.h>
void main()
{
printf("Hello World");
}"
document.forms.myform.area.value=text1;
}
</script>
<div>
<button onclick="fill()">Program 1</button>
<button>Program 2</button>
<button>Program 3 </button>
<button>Program 4</button>
</div>
<div class="wrapper">
<div class="gfg">
<form name="myform">
<textarea name="area" rows="30" cols="60">
</textarea>
</form>
</div>
</div>
</body>
</html>

You can simply use Template string ``
var text1 =`#include<stdio.h>
#include<conio.h>
void main()
{
printf("Hello World");
}`

In ES5 multiline text can be escaped with a backslash character ( \\ ).
var text1 = "#include<stdio.h> \
#include<conio.h> \
void main() \
{ \
printf(\"Hello World\"); \
}";
If you are using ES6 you can use backticks to wrap multiline strings.
var text1 = `#include<stdio.h>
#include<conio.h>
void main()
{
printf("Hello World");
}`;
