In my application, I am creating a unique feature where users can trigger a window to appear by inputting the symbol @ (shift + 50). This will allow them to access predefined variables...
<textarea @keyup.shift.50="showWindow"></textarea>
My query is: I want the window to only pop up when the user presses the keys twice in a row, not just once. Is this achievable?
============REVAMPED========================================
Edit: I have significantly improved and optimized the code for better performance. The modified code does not contain any 'bugs' and operates more efficiently compared to the previous version.
Explanation: The updated code now tracks all 'shift.50' key presses and compares their time intervals. It ensures that if you press 'shift.50', you need to wait at least 5 minutes before pressing it again to trigger the 'do the needful' event. This modification requires three consecutive clicks of 'shift.50' to activate the event.

var myapp = new Vue({
el: '#app',
data: {
delta: 1000, // in ms
keyPress: null,
},
methods: {
keyPressed(key) {
if(this.keyPress !== null){
let d = key.timeStamp - this.keyPress.timeStamp;
if(this.delta > d){
alert('do something here!')
}
}
this.keyPress = key;
},
}
})
.
.
=============ENHANCED=========================================
Explanation: The original code stored the number of times 'shift.50' button was clicked in the property 'pressCount'. By comparing the time interval between two key presses with the specified 'delta' value, it determined whether the action should be triggered. However, the revised code provides a more streamlined approach to achieve the same functionality with improved efficiency.

var myapp = new Vue({
el: '#app',
data: {
delta: 1000, // in ms
pressCount: 0,
firstPress: null,
},
methods: {
keyPressed(key) {
this.pressCount++;
if(this.pressCount === 1){
this.firstPress = key;
}
if(this.pressCount === 2){
let d = key.timeStamp - this.firstPress.timeStamp
if(this.delta > d){
alert("do something here");
}
this.pressCount = 0;
}
},
}
})
