Question

我为内容滑块编写了一个简单的jquery脚本。我的问题是，在滑动内容时，屏幕总是跳到父div的顶部位置。我已经尝试了返回false和preventDefault来应对这种效果，但是这两个只是让脚本不再工作了，当我点击链接时没有任何反应..

所以这是jquery代码：

$(document).ready(function (){

var itemCount = $('.container div').size();
var itemWidth = $('.container div').width();


$('.container').wrap('<div id="AboutSlider"></div>');

$('#AboutSlider').css({'width':'640px', 'overflow':'hidden', 'position':'relative', 'height':'400px'});

$('#AboutSlider .container').css({'width':itemCount*itemWidth+'px', 'position':'absolute', 'height':'400px'});

$('.container .aboutContent').css({'padding-left':'0px'});

$('#AboutSlider .aboutContent').css({'width':'640px', 'float':'left', 'min-height':'400px'});


$('#AboutNav a').click(function(){

        var integer = $(this).attr('rel');

        $('#AboutSlider .container').animate({left:-640*(parseInt(integer)-1)})  

        $('#AboutNav a').each(function(){
        $(this).removeClass('active');
            if($(this).hasClass('button'+integer)){
                $(this).addClass('active')}
        });

    });

}）;

这里有各自的html位：

<div id="Dienstleistungen">
                        <div class="left_column">
                        <h2>Meine Dienstleistungen</h2>
                        <h3>KOMPETENZEN</h3>
                        <ul id="AboutNav">

                            <li><h1><a href="#Frontend" class="button2" rel="2" title="Frontend Entwicklung | Sebastian B&ouml;hme">Frontend Entwicklung</a></h1></li>

有人知道吗？非常感谢提前!!

Answer 1

preventDefault看起来对我来说效果很好：

$('#AboutNav a').click(function(event) {
    event.preventDefault();

    var integer = $(this).attr("rel");

    $('#AboutSlider .container').animate({
        left: -640 * (parseInt(integer) - 1)
    })

    $('#AboutNav a').each(function() {
        $(this).removeClass('active');
        if ($(this).hasClass('button' + integer)) {
            $(this).addClass('active')
        }
    });

});

在此工作：http://jsfiddle.net/79Rzh/

其他说明：

您可以替换此代码：

$('#AboutNav a').each(function(){
    $(this).removeClass('active');
    if($(this).hasClass('button'+integer)) {
        $(this).addClass('active')
    }
});

有了这个：

$("#AboutNav a").removeClass("active");
$(this).addClass('active');

还要考虑一遍又一遍地使用的缓存选择器（var $this = $(this);）。
此外，请确保将基数参数传递给parseInt()（parseInt(integer, 10)

jquery跳转到click事件的顶部，返回false或prevenDefault不起作用
