JavaScript - document

  1. The document.getElementById () method returns the element of specified id. In the previous page, we have used document.form1.name.value to get the value of the input value. Instead of this, we can use document.getElementById () method to get value of the input text. But we need to define id for the input field
  2. The getElementById () is a DOM method used to return the element that has the ID attribute with the specified value. This is one of the most common methods in the HTML DOM and is used almost every time we want to manipulate an element on our document. This method returns null if no elements with the specified ID exists
  3. The document.getElementById () method in JavaScript returns the element of a specified id. In order to get the value of the input text document. getElementById method is used and the id of the input field needs to be defined
  4. document.getElementById ('id') - returns a reference to the whole HTML element that has thad id . The object returned by getElementById () contains properties and methods to can work with the component parts of that element (attributes, content). See the list from the page
  5. var someOtherName=abc; // ^^^^^ document.getElementById('msg').value = someOtherName; document.getElementById('sp_100').checked = true; There is a chance (in your original code) that IE attempts to set the value of the input to a reference to that actual element (ignores the error) but leaves you with no new value
  6. There are many ways of accessing form elements, of which the easiest is by using the cross-browser W3C DOM document.getElementById() method. Before we learn more about this method, it would be useful to know something about the Document Object Model (DOM), the concept of HTML nodes or elements, and the concept of containers

The selectedIndex property of the select list specifies the location of the selected option in the node list. The text property of an option is the content of the option element.. Using a for Loop to Obtain Selected Option. You can use a for loop to iterate through the options of a select. the document.getElementById(id_string).value is returning undefined. I have confirmed that the id is being passed correctly to the doSubmit function and that the element exists browser.ExecuteScriptAsync(document.getElementById('Password')) Which in turn I can set the value/text of said text box's by using this code.
