display counter on screen and store count

[KarenW]

Hi I'm new to appery .
I want a user to be able to have a user press a button and have it count the number of times it has been pressed. I want this displayed on the screen next to the button - like a counter. I also want to store the total count. What is the easiest way to achieve this please
cheers
Karen

Hi Karen,

You can achieve this using JavaScript with jQuery, this is one of the ways:
Let's assume you have the Label component and the Button on your page - on button click event add this JS:
precode
Apperyio('your_label').text( function(i, val) { return +val+1; });
// this will return value iteration inside the label each time you click the button
/code/pre
On another button you can store the final cont value inside the local storage variable, on button click event add this JS:
precode
var counts = Apperyio('your_label').text();
// here we put the current value inside the label component in variable 'counts'
// and store this value inside the local storage variable for later usage in your app
localStorage.setItem('total_counter', counts);
/code/pre
