Question

i have a page with many divs on which i need to implement some JavaScript functions. Is there a way to tell the browser to sort all divs by for example id so that I can find quickly an element.I generally don’t know how browsers handle searching of elements, is there some sorting or not on major browsers firefox, chrome, ie? How do elements get indexed?

Answer 1

the browsers creates a tree like structure named DOM (Document Object Model), with the root being the html tag for example, then it’s children, their children’s children, etc..

There are functions that let’s you access the DOM and find the required elements. But this is done in the browser’s inner implementation. You can not change how it handles the page elements, just use the browser’s API to locate elements
