![]() ![]() It’s forbidden to generate “custom” clipboard events with dispatchEvent in all browsers except Firefox. So most browsers allow seamless read/write access to the clipboard only in the scope of certain user actions, such as copying/pasting etc. A user may switch between various applications, copy/paste different things, and a browser page shouldn’t see all that. The clipboard is a “global” OS-level thing. More about it in the specification Clipboard API and events, not supported by Firefox. It’s a bit beyond our scope now, but you can find its methods in the DataTransfer specification.Īlso, there’s an additional asynchronous API of accessing the clipboard: navigator.clipboard. That’s because clipboardData implements DataTransfer interface, commonly used for drag’n’drop and copy/pasting. For instance, we can copy a file in the OS file manager, and paste it. It’s possible to copy/paste not just text, but everything. You can find more details about document selection in the article Selection and Range. ![]() So the example above uses document.getSelection() to get the selected text. If we use event.preventDefault() it won’t be copied at all. That’s because technically the data isn’t in the clipboard yet. So, you can create a function that store value in object on keyup or keydown event.Ĭonsole.log(data.Please note: inside cut and copy event handlers a call to (.) returns an empty string. We need to write four lines to fetch the value of an input field. Thenĭocument.getElementById('something').value is annoying. You can use onkeyup when you have more than one input field. document.querySelectorAll('').value selected by name.document.querySelectorAll('input').value selected by tagname.document.querySelectorAll('.searchField').value selected by class. ![]() document.querySelectorAll('#searchTxt').value selected by id.document.querySelector('').value selected by nameĭocument.querySelectorAll('selector').value which also uses a CSS selector to select elements, but it returns all elements with that selector as a static Nodelist.document.querySelector('input').value selected by tagname.document.querySelector('.searchField').value selected by class.document.querySelector('#searchTxt').value selected by id.Use the powerful document.querySelector('selector').value which uses a CSS selector to select the element For example Method 4ĭocument.getElementsByName('name').value which also >returns a live NodeList For exampleĭocument.getElementsByName("searchTxt").value if this is the first textbox with name 'searchtext' in your page. Use document.getElementsByTagName('tag_name').value which also returns a live HTMLCollection For exampleĭocument.getElementsByTagName("input").value, if this is the first textbox in your page. Method 2ĭocument.getElementsB圜lassName('class_name').value which returns a Live HTMLCollection For exampleĭocument.getElementsB圜lassName("searchField").value if this is the first textbox in your page. For the first element, use ,įor the second one use, and so on. Note: Method 2,3,4 and 6 returns a collection of elements, so use to get the desired occurrence. ![]() There are various methods to get an input textbox value directly (without wrapping the input element inside a form element): Method 1ĭocument.getElementById('textbox_id').value to get the value ofĭocument.getElementById("searchTxt").value ![]()
