<area> 标签上的 preventDefault() 似乎不可能

Question

在这个站点中，我使用 Fancybox 2 来触发显示一些内容的弹出窗口：http://www.basing.nl/demo/cole/index.html

在顶部菜单中点击“Ontdekken”，然后点击“文件夹”。

问题

弹出窗口打开，但窗口滚动到页面顶部。

原因

我认为这是因为标签没有 preventDefault() 动作，使浏览器保持默认动作。

JS：

var coleApp = (function(){

    //global variables
    var animationArray = []
    var currentPosition
    var i = 0
    var windowWidth


    // public functions
    return {

        //end the animation? 1 = yes
        endAnimation:0,
        test: animationArray,

        fullscreen: function(callback){

            var screenHeight = window.innerHeight
            screenHeight = screenHeight - 96
            $(".fullscreen").css("height", screenHeight)

            //not needed anymore for some reason...?
            if(callback){

                setTimeout(callback, 1000)

            }

        },

        setWindowWidth: function(){

            windowWidth = window.innerWidth
            console.log(windowWidth)

        },

        initialise:function(){

            $(document).foundation();
            $('img[usemap]').rwdImageMaps();
            $('.fancybox').fancybox();
            $(".fancybox").click(function(e){

                e.preventDefault();

            })

        },

        ontdekkenGallery:function(){

            $("#ontdekkenGallery").click(function() {
                $.fancybox.open([
                    {
                        href : 'cssObjects/assets/img/figureCole.jpg',
                        title : 'jow'
                    }, {
                        href : 'cssObjects/assets/img/figureCole.jpg',

                    }
                ]);
            });

        },

        addAnimationClass:function(){

            currentPosition = window.pageYOffset
            var windowHeightHalf = Math.round(window.innerHeight / 2)

            if(i < animationArray.length && animationArray[i].executed == 0){

                if(currentPosition > (animationArray[i].position - windowHeightHalf)){

                    $(animationArray[i].element).addClass("activateAnimation")
                    animationArray[i].executed = 1
                    i = i+1

                animationElementPosition  = Math.round(animationElement[0].offsetTop)

                toBeSaved.element = animationElement
                toBeSaved.position = animationElementPosition

有谁知道如何防止标签上的默认操作使浏览器停留在同一位置？

Answer 1

你需要使用助手：

$('[selector]').fancybox({
  padding: 0,
  helpers: {
    overlay: {
      locked: false
    }
  }
});
