Let's say i create dynamically some divs, each has it's dynamically created id (div0, div1, div2, etc.) and i'd like with a function to pass through currently existent divs and put their innerHTML into an array (one, two, three in this case), how can i achieve this in javascript?

html example:

<div contenteditable="false" id="div0">
  <a href="#">one</a>
  <span id="one-close">
    <i class="material-icons">close</i>
  </span>
</div>
<div contenteditable="false" id="div1">
  <a href="#">two</a>
  <span id="two-close">
    <i class="material-icons">close</i>
  </span>
</div>
<div contenteditable="false" id="div2">
  <a href="#">three</a>
  <span id="three-close">
    <i class="material-icons">close</i>
  </span>
</div>

• javascript
• arrays
• innerhtml

• $('div') (Or your custom selector, like $('#divcontainer > div')) should already be an array. You can use .map() to get the html into an array: $('#divcontainer > div').map(el => $(el).html()) – Blue Commented Aug 26, 2018 at 11:42

You could also use spread syntax

const divsContents = [...document.querySelectorAll("div>a")].map(e=>e.innerHTML);
console.log(divsContents);

<div contenteditable="false" id="div0">
  <a href="#">one</a>
  <span id="one-close">
    <i class="material-icons">close</i>
  </span>
</div>
<div contenteditable="false" id="div1">
  <a href="#">two</a>
  <span id="two-close">
    <i class="material-icons">close</i>
  </span>
</div>
<div contenteditable="false" id="div2">
  <a href="#">three</a>
  <span id="three-close">
    <i class="material-icons">close</i>
  </span>
</div>

Using some magic from here, because document.querySelectorAll returns a NodeList and not an array, we can get the div elements into an array and use .map() to return the div content into an array.

var divs = [].slice.call(document.querySelectorAll('div'));

console.log(divs.map(div => div.innerHTML));

<div contenteditable="false" id="div0">
  <a href="#">one</a>
  <span id="one-close">
    <i class="material-icons">close</i>
  </span>
</div>
<div contenteditable="false" id="div1">
  <a href="#">two</a>
  <span id="two-close">
    <i class="material-icons">close</i>
  </span>
</div>
<div contenteditable="false" id="div2">
  <a href="#">three</a>
  <span id="three-close">
    <i class="material-icons">close</i>
  </span>
</div>

Ideally you should be using a selector like #divcontainer > div to fetch all the divs in the container, but if you know all the ID's, you can use a selector such as:

document.querySelectorAll('#div0, #div1, #div2')

you can use jquery or javascript function for get your div:

myArray[0] = document.getElementByID("div0").innerHtml;
myArray[1] = document.getElementByID("div1").innerHtml;
myArray[2] = document.getElementByID("div2").innerHtml;

Give same class to divs and access by $('.class-name') or add a container div and get your div array by $('#divId div').

Use a loop after creating a divs collection using querySelectorAll:

let divs = document.querySelectorAll('div');
let arr = [];


for (let i = 0; i < divs.length; i++) {
  arr.push(divs[i].innerHTML);
}

console.log(arr);

<div>hi</div>
<div>hi2</div>
<div>hi3</div>

Here is your solution

var arr = [];
function myFunction() {
  var anchors = document.getElementsByTagName("a");
  for(var i = 0; i < anchors.length; i++){
   arr.push(anchors[i].text);
  }
}

console.log(arr);

So many ways of doing this. Yet an other way: using ES6 Array.from

let divsA = Array.from(document.querySelectorAll("[id^='div'] a"));
divsA.map(a => console.log(a.innerHTML));

<div contenteditable="false" id="div0">
  <a href="#">one</a>
  <span id="one-close">
    <i class="material-icons">close</i>
  </span>
</div>
<div contenteditable="false" id="div1">
  <a href="#">two</a>
  <span id="two-close">
    <i class="material-icons">close</i>
  </span>
</div>
<div contenteditable="false" id="div2">
  <a href="#">three</a>
  <span id="three-close">
    <i class="material-icons">close</i>
  </span>
</div>
