document.write text over multiple lines
javascript
Solution
You can add breaks in the string using `replace` and a regular expression. This adds a break at every 100th character:
document.write(theText.replace(/(.{100})/g, '$1<br/>'));
Problem
I have a script that takes an input string from a user with variable length, typically ~ 400-3000 letters. My script does some modification to the string, and then should print it to the screen. Using document write, everything appears on one line. However, I want to have ~ 100 letters for each output line, so the user won't have to scroll ~ 3000 letters to the right to see the whole text. The only way I could imagine to do this would be a for loop, but maybe someone know a better solution? Edit: This is the for loop I am currently using to achieve this ``` document.write("<p>",">Position: ", (lower+1) + "-" + (lower +print_screen.length), "<br/>"); // print only 70 chars per line for(i = 0; i < print_screen.length; i += 69){ document.write(print_screen.substring(i, i+69), "<br/>"); }; document.write("</p>"); ```
