1.<input id="kw1"></input>

2.<input></input>

The first one, I can use document.getElementById to get the object, but on some websites, like the second, there is no id in element, but I also want to get the object. How can I do this ? And do not use JQuery

• javascript

• document.getElementsByTagName('input') gives array of input elements. – Mr_Green Commented Jul 4, 2014 at 8:05
• If you want to match that specific element, you will need something to distinguish it from the others. Either a matchable ancestor element (by id or class, for instance), or the index of that <input> element relative to the other elements of the same type. – Frédéric Hamidi Commented Jul 4, 2014 at 8:08

• How strange that the DOM was designed with no inherent identification, no serial number, for each node. Was this to save a little space? Nodes have forward and backward links, so saving space was not a primary concern. Was it, then, an oversight? – David Spector Commented Aug 20, 2023 at 17:08

you can do this by using :

getElementsByTagName

example :

var elements = document.getElementsByTagName('input'); // returns array

Use document.getElementsByTagName('input') instead.

It'll return you an array with every input.

You can use document.getElementsByTagName('input'), but this give you all input elements.

But since you have nothing else to identify that element, you can not be more specific.

You can use:

document.getElementsByTagName("input");

which will return a list of objects of type "input"
