javascript 如何实现 jScroll？

How to implement jScroll?

提问by Blaze Tama

Im a beginner in JS & jQuery so please bear with me.

我是 JS 和 jQuery 的初学者，所以请耐心等待。

Im trying to create a dynamic list <ul>using JS and finally its working. Now i need to implement the infinite scrolling concept in my list, using jScrollplugin.

我试图<ul>使用 JS创建一个动态列表，最后它的工作。现在我需要使用jScroll插件在我的列表中实现无限滚动的概念。

So i researched a lot about jScroll, but i cant find any tutorial i needed. Most of the tutorials using PHPlanguage pretty much, while in my case i have done my server (PHP) code using simple SELECTquery with LIMITand OFFSETon it and returning a json.

所以我研究了很多关于 jScroll，但我找不到任何我需要的教程。大多数教程PHP几乎都使用语言，而在我的情况下，我PHP使用简单的SELECT查询完成了我的服务器（）代码，LIMIT并OFFSET在其上返回了一个json.

This is my jQuery/AJAX code that create the dynamic list from database, its already working:

这是我从数据库创建动态列表的 jQuery/AJAX 代码，它已经在工作：

$.ajax({
    url: "http://localhost/jwmws/index.php/jwm/search/msmall/"+keyword, //This is the current doc
    type: "GET",
    error : function(jq, st, err) {
        alert(st + " : " + err);
    },
    success: function(result){
        //generate search result
        //float:left untuk hack design
        $('#search').append('<p style="float:left;">Search for : ' + keyword + '</p>'
            + '<br/>'
            + '<p>Found ' + result.length + ' results</p>');

        if(result.length == 0)
        {
            //temp
            alert("not found");
        }
        else{
            for(var i = 0; i < result.length; i++)
            {
                //generate <li>
                $('#list').append('<li class="box"><img class="picture" src="images/HotPromo/tagPhoto1.png"/><p class="name"><b>Name</b></p><p class="address">Address</p></li>');
            }

            var i=0;
            $(".box").each(function(){
                var name, address, picture = "";
                if(i < result.length)
                {
                    name = result[i].name;
                    address = result[i].address;
                    picture = result[i].boxpicture;
                }

                $(this).find(".name").html(name);
                $(this).find(".address").html(address);
                $(this).find(".picture").attr("src", picture);
                i++;
            });
        }
    }
});

Because my dynamic list is already working, now i just need to implement the jScroll. However, i dont understand its code, like :

因为我的动态列表已经在工作，现在我只需要实现 jScroll。但是，我不明白它的代码，例如：

$('.infinite-scroll').jscroll({
    loadingHtml: '<img src="loading.gif" alt="Loading" /> Loading...',
    padding: 20,
    nextSelector: 'a.jscroll-next:last',
    contentSelector: 'li'
});

How to implement this in my case? I just append <li>in my jQUery/AJAX so how about the nextSelector?

在我的情况下如何实现这一点？我只是附加<li>在我的 jQUEry/AJAX 中，那么nextSelector?

Any help is appreciated, please just ask if you have some question.

You hava every thing prety much set just needed to call jscroll at proper time.

您几乎设置了所有需要在适当的时间调用 jscroll 的东西。

$.ajax({
        url: "http://localhost/jwmws/index.php/jwm/search/msmall/"+keyword, //This is the current doc
        type: "GET",
        error : function(jq, st, err) {
            alert(st + " : " + err);
        },
        success: function(result){
            //generate search result
            //float:left untuk hack design
            $('#search').append('<p style="float:left;">Search for : ' + keyword + '</p>'
                            + '<br/>' 
                            + '<p>Found ' + result.length + ' results</p>');

            if(result.length == 0)
            {
                //temp
                alert("not found");
            }
            else{
                for(var i = 0; i < result.length; i++)
                {
                    //generate <li>
                    $('#list').append('<li class="box"><img class="picture" src="images/HotPromo/tagPhoto1.png"/><p class="name"><b>Name</b></p><p class="address">Address</p></li>');
                }
                //After generation of <li> put a next link
                $('#list').append('<a href="#" class="jscroll-next">NEXT</a>');
                //call to jscroller to be triggered
                jscroller();
                var i=0;
                $(".box").each(function(){
                    var name, address, picture = "";
                    if(i < result.length)
                    {
                        name = result[i].name;
                        address = result[i].address;
                        picture = result[i].boxpicture;
                    }

                    $(this).find(".name").html(name);
                    $(this).find(".address").html(address);
                    $(this).find(".picture").attr("src", picture);
                    i++;
                });
            }
        }
        });

//The function to be called when <li> are rendered.
function jscroller(){
 $('.infinite-scroll').jscroll({
     loadingHtml: '<img src="loading.gif" alt="Loading" /> Loading...',
     padding: 20,
     nextSelector: 'a.jscroll-next:last',
     contentSelector: 'li'
 });
}
