jQuery双提交保护不在safari中工作

Question

我们为客户提供付款明细表，以及＆＃34; Next＆＃34;按钮被多次点击，我们有保护，不允许创建两个策略。

适用于Chrome，Firefox和EVEN INTERNET EXPLORER 8！可悲的是，它没有在Safari中工作。

有人可以看看下面的代码并帮我们解决这个问题吗？

    $("form").submit(function(event) {
    //validate
    if( $(this).find(".e-clicked").attr("id") === "next" ) { 
        $( this ).find("input[type='submit']").removeClass("e-clicked");
    // console.log("submit event: " + event.srcElement);
        resetGlobalErrors();
        if (fieldsets.get("your-payment").isValid(true)) {
            //protect submit if it's validated ok
            var val = $("input[type=submit]:focus").val();
            var clicked = $("input[type=submit]:focus")
                    .hasClass("preventSubmit");     
            if (val == "Next") {
                if (!clicked) {
                    $("input[type=submit]:focus").addClass(
                            "preventSubmit");
    //                      console.log("not clicked")
                } else {
                    event.preventDefault();
    //                      console.log("clicked")
                }
            }               
            return true
        } else {
    //              $("#next").removeClass("preventSubmit");
            event.preventDefault();              
            return false;
        }
    };
}); 

$(".change-details").click(function() { 
    $(this).parent().hide();
    $(this).parent().next().show();
});
    });


    $("#next").click(function(e){

$(this).addClass("e-clicked"); //define which submit was clicked by adding a class to it

    });
