Here is the final code: document. In order to fix this, we need to add another if statement into our detectTabKey() function.
#USE EVENT KEY OUTSIDE KEYUP FUNCTION JAVASCRIPT CODE#
If we keep the same JavaScript code as before, the output will look like this: If you want to handle keyboard shortcuts within a BrowserWindow, you can listen for the keyup and keydown DOM events inside the renderer process using the. For example, its called when the user clicks outside of. Let’s add a new element into our HTML code: Test Link 1 The onBlur event handler is called when focus has left the element (or left some element inside of it). To ensure that doesn’t happen, we need to add a step into our detectTabKey() function.
Thankfully, JavaScript will not throw an error if that’s the case, but it will print out undefined whenever a text input is selected. Some of you may have already spotted an issue with the previous method: What happens if our webpage has input text boxes? If that is the case, pressing the Tab key will also cycle through them, and since they have no href attribute, our function will not work as intended. Add More Logic to Ensure Only Elements Trigger the Event Listener If it is a match, print the hyperlink to the console. Our custom detectTabKey() function checks if the key code for the event is the same as the one for the Tab key.The document.addEventListener() method takes two arguments: the kind of event you want to listen for (in this case, it is the keyup event), and the function you use want to execute when the event is triggered.The JavaScript code above has two working parts:
Here is an example of how you can add an event listener for the Tab key: Create an Event Listener to Detect When the Tab Key Is Pressed in JavaScript Test Link 1ĭocument.addEventListener("keyup", detectTabKey) For example, you may want to do something with the selected hyperlink or even change the properties of the text input whenever a user switches to it using Tab. However, you can still detect this event using JavaScript and perform specific actions whenever the Tab key is pressed. The same is true for the Tab key, which is used to cycle through hyperlinks and text boxes in most browsers. Virtual Keyboard in JavaScript with Source Code | JavaScript Project with Source Code
