Text input division

p5.js Coding Questions

Hi! I am new here.
I am now creating a text input and output.
I could show the text input on the screen but I don’t know how can I divide the text and just go to the next line automatically. (Because the text input will be quite long…)
I know how to split it… but I don’t know how can I use ‘\n’ here…
Because this is input so I don’t know what others will put in.

Here my code…(only greet function for showing)

function greet() {
const name = input.value();

if(name != “” && name != " "){
// greeting.html(‘By’);
input.value(’’);
let message = createElement(‘h2’, ‘’);
button = createButton(’’)
let x = xOffset;
let y = (height-60)/nameCount*counter;
message.position(xOffset,30+y-yOffset);
message.html(name.split(’ ')); // here is showing the input, but I don’t know how can I divide it…
message.style(“background-color”, bgColor1)
counter++;
}
if(counter > nameCount-1){
greeting.html(‘Solution?’);
//r = r2;
xOffset = width-300;
yOffset = height-100;
bgColor1 = bgColor2;
}
}

Thank you guys… I really need your help

You will probably get a better response if you1

  1. format your code (there’s a button in the editor)
  2. provide a minimal, complete, reproducible example code instead of a single function that relies on many other global variables.

In normal processing you can simply use text() with 5 parameters

Then the text is arranged automatically inside a rectangle.



String myText = "Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Aenean commodo ligula eget dolor. Aenean massa. Cum sociis natoque penatibus et magnis dis parturient montes, nascetur ridiculus mus. Donec quam felis, ultricies nec, pellentesque eu, pretium quis, sem. Nulla consequat massa quis enim. Donec pede justo, fringilla vel, aliquet nec, vulputate eget, arcu. In enim justo, rhoncus ut, imperdiet a, venenatis vitae, justo. Nullam dictum felis eu pede mollis pretium. Integer tincidunt. Cras dapibus. Vivamus elementum semper nisi. Aenean vulputate eleifend tellus. Aenean leo ligula, porttitor eu, consequat vitae, eleifend ac, enim. Aliquam lorem ante, dapibus in, viverra quis, feugiat a, tellus. Phasellus viverra nulla ut metus varius laoreet. Quisque rutrum. Aenean imperdiet. Etiam ultricies nisi vel augue. Curabitur ullamcorper ultricies nisi. Nam eget dui. Etiam rhoncus. Maecenas tempus, tellus eget condimentum rhoncus, sem quam semper libero, sit amet adipiscing sem neque sed ipsum. Nam quam nunc, blandit vel, luctus pulvinar, hendrerit id, lorem. Maecenas nec odio et ante tincidunt tempus. Donec vitae sapien ut libero venenatis faucibus. Nullam quis ante. Etiam sit amet orci eget eros faucibus tincidunt. Duis leo. Sed fringilla mauris sit amet nibh. Donec sodales sagittis magna. Sed consequat, leo eget bibendum sodales, augue velit cursus nunc, ";

size(700, 700);

text(myText, 
  40, 40, 190, 4000);

Alternatively

Alternatively you would use split() to bring the String in an array (String[]). Then you would add the single words up to a certain length of the section and show the section
and repeat.

Here is a similar idea with a fixed number of 6 words:



String myText = "Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Aenean commodo ligula eget dolor. Aenean massa. Cum sociis natoque penatibus et magnis dis parturient montes, nascetur ridiculus mus. Donec quam felis, ultricies nec, pellentesque eu, pretium quis, sem. Nulla consequat massa quis enim. Donec pede justo, fringilla vel, aliquet nec, vulputate eget, arcu. In enim justo, rhoncus ut, imperdiet a, venenatis vitae, justo. Nullam dictum felis eu pede mollis pretium. Integer tincidunt. Cras dapibus. Vivamus elementum semper nisi. Aenean vulputate eleifend tellus. Aenean leo ligula, porttitor eu, consequat vitae, eleifend ac, enim. Aliquam lorem ante, dapibus in, viverra quis, feugiat a, tellus. Phasellus viverra nulla ut metus varius laoreet. Quisque rutrum. Aenean imperdiet. Etiam ultricies nisi vel augue. Curabitur ullamcorper ultricies nisi. Nam eget dui. Etiam rhoncus. Maecenas tempus, tellus eget condimentum rhoncus, sem quam semper libero, sit amet adipiscing sem neque sed ipsum. Nam quam nunc, blandit vel, luctus pulvinar, hendrerit id, lorem. Maecenas nec odio et ante tincidunt tempus. Donec vitae sapien ut libero venenatis faucibus. Nullam quis ante. Etiam sit amet orci eget eros faucibus tincidunt. Duis leo. Sed fringilla mauris sit amet nibh. Donec sodales sagittis magna. Sed consequat, leo eget bibendum sodales, augue velit cursus nunc, ";

size(700, 700);

String[] strArray = split(myText, " "); 

int a = 0; 

while (a+6<strArray.length) {
  String myText1="";
  // take 6 words 
  for (int i=0; i<6; i++) {
    myText1+=strArray[a+i]+" ";
  }  
  // show 6 words 
  text(myText1, 
    40, 40+a*3);
  // next section 
  a += 6;
}
//

Warm regards,
