I have a function:
function loremIpsum() {
$('.element').fadeIn()
}
to show a hidden Element - The issue is, that a user can go back with a second button and call the loremIpsum() function again, but the function should be called just once. Can I limit that in someway ? I couldn't find a Post for that here.
I tried this:
function loremIpsum() {
var executed = false;
return function() {
if (!executed) {
executed = true;
$('.element').fadeOut()
}
}
}
But that didn't work
You can use sessionStorage to keep track of executed boolean value for the session.
function loremIpsum() {
sessionStorage.setItem('executed', true);
$('.element').fadeIn();
}
And in the caller, you can check:
if (!(sessionStorage.getItem('executed') === "true")) { //since sessionStorage stores items as strings
loremIpsum();
}
function loremIpsum() {
loremIpsum= function() {};
$('.element').fadeIn()
}
Did work - nevermind then.
