Skipping a tag in JS

Question

Does anyone know how you would skip a tag?

For instance

<p>Hello!</p>
<p></p>
<p></p>
<p></p>

I have some JS that is going to output 8 calculations to the p tags but I dont want the first p tag to be changed. I will have 9 p tags but the last 8 need change?

JS is document.getElementsByTagName("p")[i].innerHTML = planetAge + " years old.";

Answer 1

Angelina Ahh that's what was required, link to the full code. Use '<=' (less than equal to) instead of < (less than) ;)

for (i = 1; i <= planets.length; i++)

and rest of the code as is!

Edit: Because the index now starts from 1, so <= is mandatory to change the tag for every planet.

Answer 2

Angelina, use this and try again:

for (i = 1; i < planets.length; i++) {
var planetAge = age / planets[i - 1].orbit;
document.getElementsByTagName("p")[i].innerHTML = planetAge + " years old.";
}

Answer 3

Angelina Oops, sorry I just messed it up. Check Rahul 's solution. That would work!

Answer 4

Are you using a for loop? You can just start i at 1 instead of 0

Answer 5

Use this:
var array = document.getElementsByTagName(“p”;
for(int i=1; i < array.length;i++){
array[i].innerHTML = text;
}
It won’t use the first, but will get the last

Answer 6

Doing the above doesn't calculate the correct ages :/

Answer 7

If it helps I have added code to my profile, also you can find it in codepen.

Answer 8

Thank you so much! Didnt even think of that

Answer 9

@Ariela

If I do that then my last calculation is missed out as it has reached my .length by the time it gets to the last <p>

Answer 10

Thats changing the first p tag again. This is the code I currently have and it works fine if I dont have the first p tag in my HTML.

for (i = 0; i < planets.length; i++) {
var planetAge = age / planets[i].orbit;
document.getElementsByTagName("p")[i].innerHTML = planetAge + " years old.";
}

Answer 11

I didn't even see Rahul's solution, I have tried it and it still missing the last P tag and isn't replacing the text already in the P tag.

Answer 12
