有人可以帮助我将此代码转换为import requests import time exts = ['conf', 'bak', 'swp', 'txt', 'old', 'tar', 'gz', 'bz2', 'zip'] pre = ['old', 'bak', 'backup', 'copyof'] session = requests.head("http://challenge01.root-me.org/") if session.status_code == 200: print "[i] Connection is working." http = "http://challenge01.root-me.org" file = "/realiste/ch1/login.php" urls = [] codes = [] def store(request, code): urls.append(request) codes.append(code) for ext in exts: req = http + file + "." + ext connection = requests.head(req) store(req, connection.status_code) time.sleep(0.1) for search in range(0, len(codes)): ecx = 1 if codes[search] != 404: print "=============" print "[" + str(ecx) + "] URL ::: " + urls[search].replace("\n", "").replace("\r", "") print "|__ COD ::: " + str(codes[search]) print "=============" print "[*] Done."吗？

这是您的代码插件。 jquery How to Create a Basic Plugin页面对于学习如何制作插件非常有用。

(function($) {

    var isScrolledIntoView = function($element) {
        var windowTop = $(window).scrollTop();
        var windowBottom = windowTop + $(window).height();
        var elementTop = $element.offset().top; 
        var elementBottom = elementTop + $element.height();

        return (elementBottom <= windowBottom) && (elementTop >= windowTop);
    };

    $.fn.addClassOnScrollVisible = function(className) {
        var $collection = this;     // the jQuery set the plugin is acting on

        $(window).on("scroll", function() {

            // loop over each element in the collection
            $collection.each(function() {
                var $element = $(this);

                if (isScrolledIntoView($element)) {
                  $element.addClass(className);
                } else {
                  $element.removeClass(className);
                }
            });
        });

        return $collection;     // return the input collection
    };

}(jQuery));

// Usage example:
$(".button").addClassOnScrollVisible("in");

把它变成一个jQuery插件
