"grey", "lightcyan", "coral", "lightpink", "yellow", "forestgreen", "khaki", "indigo" Width: 800px height: 500px padding: 20px font-size: medium text-align: center margin: auto īorder: 3px solid cornflowerblue margin-top: 50px Now, consider a different example demonstrating the effect of keyup() method. After the pressed key is released, the background color of the input field changes to teal as shown below.
Once any key is pressed down inside the input field, the background color changes to blue as shown in the below screenshot.At this point in time, no activity has been performed.The below screenshot is taken when the page is first loaded in the browser.In a similar mannner, once the key is released, keyup event gets triggered which invokes keyup() method to execute the attached function to chnage the background color of the input field.
The reason behind this is when any key is pressed down, keydown event gets triggered which invokes keydown() method to execute the attached function to change the background color of the input field. As soon as you release the key, the background color changes to teal. Once you press any key inside the input field, the background color will change to skyblue. $("input").css("background-color", "teal") Įxample for jQuery keyup event Enter anything: Let us now see an example illustrating the order of events keydown() and keyup(). In the above example, we saw that as soon as the key is released, the keyup event is triggered which in turn executes the attached function that changes the background color. Background color changes to yellow once this button is clicked.The reset button is clicked to try entering the value again in the text box.This function on execution changes the background color to coral.The keyup event occurs once a key is released, which in turn makes the keyup() method to execute the attached function.The reason behind this color change is that the jQuery keyup() method attaches a function to the selected input box as soon as the keyup event is triggered on releasing the key.Now, as we press any key and release it, the background color of the input box changes to coral as shown in the screenshot below.At this point, the background color of the text field is white with no input provided.The below screen gets displayed when the page is first loaded in the browser.Width: 400px height: 300px padding: 20px font-size: medium margin: auto īorder: 3px solid cornflowerblue background: lightgray Įxample for jQuery keyup event Enter any value: Įnter anything in the text box, and the background color will change on key up. $("input:text").css("background-color", "yellow") $("input:text").css("background-color", "coral") This example is the illustration of the working of the keyup() method. Given below are the examples mentioned : Example #1 keyup: Event is triggered, that is, each time a key is released.
