jQuery通过点击按钮从网站上删除所有js

我的网站concept studio在那个页面上遇到了一些问题，我在表单上键入了动画，我需要在页面中添加一些跳过动画的按钮，但我不知道该怎么做。

function doTypeAnimation() {
    if ($(".hello-form").length === 0) return false;
    function condition(functionName) {
        if (functionName === 0) {
            return false;
        } else if (functionName == 1) {
            finish();
        } else if (functionName == 2) {
            runSecond();
        } else if (functionName == 2.1) {
            runSecondOther();
        } else if (functionName == 3) {
            runThird();
        } else if (functionName == 4) {
            runFourth();
        } else if (functionName == 5) {
            runFifth();
        } else if (functionName == 6) {
            runSixth();
        } else if (functionName == 7) {
            runSeventh();
        } else if (functionName == 8) {
            runEighth();
        } else if (functionName == 8.1) {
            runEighthOne();
        } else if (functionName == 8.2) {
            runEighthTwo();
        } else if (functionName == 9) {
            runNinth();
        } else if (functionName == 10) {
            runTenth();
        }
    }
    var anim = {

    $(".hello-form").on('keyup', 'span', function(e) {
        var keyCode = e.keyCode || e.which;
        if (keyCode == 9) {
            var text = $(this).text();
            var placeholder = $(this).attr("data-placeholder");
            if (text == placeholder) {
                $(this).text('');
            }
        }
    });
}

这个函数完成了页面上的所有动画，你可以在给定的url上看到动画示例。
