Minified jQuery

Copy
jQuery Script Before Formatting
$(function(){var $b=$("body");$("form.ajax").on("submit",function(e){e.preventDefault();var $f=$(this),u=$f.attr("action")||"/",d=$f.serialize();$.post(u,d).done(function(r){$f.find(".result").html(r)}).fail(function(){alert("Request failed")})});$(".toggle").on("click",function(){var s=$(this).data("target");$(s).toggleClass("hidden")})});var t=()=>1;t();localStorage.v=1;window.c=1;document.c=2;

Beautified jQuery

Copy
jQuery Script After Formatting
$(function() {
    var $b = $("body");
    $("form.ajax").on("submit", function(e) {
        e.preventDefault();
        var $f = $(this),
            u = $f.attr("action") || "/",
            d = $f.serialize();
        $.post(u, d).done(function(r) {
            $f.find(".result").html(r)
        }).fail(function() {
            alert("Request failed")
        })
    });
    $(".toggle").on("click", function() {
        var s = $(this).data("target");
        $(s).toggleClass("hidden")
    })
});
var t = () => 1;
t();
localStorage.v = 1;
window.c = 1;
document.c = 2;
