onkeydown are events triggered by users whenever they try to communicate with a web application. In this shot, we will look at the difference between the
onkeyup and the
onkeydown events. These events are related closely but they are triggered differently.
We use the two event listeners to communicate with our web application. This involves entering information in a particular section of the web application. The event listeners are normally attached directly to an HTML element where the action will be triggered or the HTML element is selected by
onkeyup() is used when selecting the tag via
onkeyup="function" // is used when attached directly to an HTML tag.
onkeyup recieves a code snippet or a function to execute.
onkeydown() is used when selecting the tag via
onkeydown="function" // is used when attached directly to an HTML tag.
onkeydown receives a code snippet or a function to execute.
Let's see a practical example to demonstrate the difference between the two event listeners.
In the code above, we can see the difference between the two event listeners.
"mySelect". We also trigger the
onkeyupevent listener using
onkeyup="myFunction()". The passed
myFunction()is used to execute the code.
"mySelect2". We also trigger the
onkeydownevent listener using
onkeydown="myFunction2()". The passed
myFunction2()is used to execute the code.
myFunctionwhich we called in the
onkeyupevent by its id.
myFunction2which we called in the
onkeydownevent by its id.
Observe how everything we enter in the field that is controlled by the
onkeyupevent is output completely, but that controlled by the
onkeydownevent is missing the last entry. That is why
onkeydownshouldn't be used for making calculations in realtime.
