In response to your query, several methods are available for retrieving the value of an input text field directly without using forms.
Method 1: Using getElementById()
document.getElementById('textbox_id').value retrieves the value of the desired text input field directly.
document.getElementById("searchTxt").value; // Get the value of the searchTxt text field
Method 2: Using getElementsByClassName()
document.getElementsByClassName('class_name')[whole_number].value returns a live HTMLCollection and can be used to select the desired text field based on its class.
document.getElementsByClassName("searchField")[0].value; // Get the value of the first text field with class "searchField"
Method 3: Using getElementsByTagName()
document.getElementsByTagName('input')[whole_number].value also returns a live HTMLCollection and allows you to select the desired text field based on its tag name.
document.getElementsByTagName("input")[0].value; // Get the value of the first text input field
Method 4: Using getElementsByName()
document.getElementsByName('name')[whole_number].value returns a live NodeList and can be used to select the desired text field based on its name attribute.
document.getElementsByName("searchTxt")[0].value; // Get the value of the first text field with name "searchTxt"
Method 5: Using querySelector()
document.querySelector('selector').value uses a CSS selector to select the desired text field.
document.querySelector('#searchTxt').value; // Get the value of the text field with id "searchTxt"
Method 6: Using querySelectorAll()
document.querySelectorAll('selector')[whole_number].value also uses a CSS selector to select the desired text field, but returns a static NodeList.
document.querySelectorAll('.searchField')[0].value; // Get the value of the first text field with class "searchField"
