I'm facing an issue with using the function I created. The codes are provided below and I keep encountering a "not a function error."
var adjustTransparency = function () { //defining the function
if ($(this).css('opacity') < '0.90') {
$(this).css('opacity', '1.00');
}
else {
$(this).css('opacity', '0.20');
}
return $(this);
};
$("#image").on("click", function () { //calling the function
$(this).adjustTransparency();
});
If you want to use a function as a jQuery method, you need to add a property to $.fn:
$.fn.alteropacity = alteropacity;
Make sure to place this line right after defining the function (outside of the event handler).
To adhere to convention and ensure your code behaves like a typical jQuery method, consider iterating through elements:
var alteropacity = function () {
return this.each(function() {
if ($(this).css('opacity') < '0.90') {
$(this).css('opacity', '1.00');
}
else {
$(this).css('opacity', '0.20');
}
});
};
This way, you can apply the method to multiple elements by using a selector like:
$(".common-class").alteropacity();
Keep in mind that within a jQuery method, this refers to the jQuery object itself. Although wrapping it again with $(this) is optional, it's recommended for clarity. Inside the .each() loop, this will refer to individual elements being processed.
