I want to run a function when a HTML <input/> tag changes. How do I do this? There are some answers for this but they are all in jQuery and I want plain javascript. Can someone give me a simple example? Thanks!
I want the input to be a type as text:
<input type="text" id="change">
953
To change the type of input it is (button to text, for example), use: myButton. type = "text"; //changes the input type from 'button' to 'text'. Another way to change or create an attribute is to use a method like element.
$() The $() function is shorthand for the getElementByID method, which, as noted above, returns the ID of a specific element of an HTML DOM. It's frequently used for manipulating elements in a document. $() allows for shorter and more efficient JavaScript coding.
In this method, we will create and define a function in the HTML document's head section. To invoke this function in the html document, we have to create a simple button and using the onclick event attribute (which is an event handler) along with it, we can call the function by clicking on the button.
You can use the input event. This will trigger not only on key up and paste, but also other text modification events such as drag & drop.
change.addEventListener("input", function (e) {
alert(this.value);
});<input type="text" id="change">If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
