By utilizing Document Object Model (DOM) objects, I aim to identify a user name and password combination along with its associated form element on a 'Log in' page.
Initially, the task involves gathering all the HTMLInputElement objects contained within the HTMLDocument object of the 'Log in' page. Subsequently, the password element is pinpointed by scrutinizing its specific attribute type="password".
Providing solutions for your question:
To locate elements, you can utilize the document.getElementsByTagName method. For example:
function searchForItems() {
var items = document.getElementsByTagName('item'),
item,
index;
for (index = 0; index < items.length; ++index) {
item = items[index];
if (item.type === 'specificType') {
// Perform actions
}
}
}
This technique should be utilized for good purposes that benefit society, rather than for any malicious intentions. ;-)
Tackling the core aspect of your query:
To generate new elements, you can use document.createElement, similar to this illustration:
var element = document.createElement('element');
element.type = "specificType";
document.getElementById('someContainer').appendChild(element);
document.querySelector
document.querySelectorAll
For instance:
document.querySelector('#header').querySelectorAll('h1')[0];
retrieves the first h1 element within the element with the ID 'header'
document.querySelectorAll('.content')[1].querySelectorAll('p')[2];
fetches the third paragraph within the second div with the class name 'content' in the document.
