  • iscroll的下拉刷新,上拉翻页。

    首先对iscroll的scrollTo方法进行稍微修改如下图:

    对iscroll滑动到屏幕边缘不能弹回的bug进行修复,如下代码:

    function scrollbug() {
        var self = this;
        if (this.maxScrollY - this.y > 50) {
            var load = $(self.wrapper).find("div.load-more");
            load.find("span.load-text").text("放开加载跟多");
            load.find("span.down-icon").removeClass("up-icon");
        } else {
    
            var load = $(self.wrapper).find("div.load-more");
            load.find("span.load-text").text("上拉加载更多");
            load.find("span.down-icon").addClass("up-icon");
        }
        if (self.y > 50) {
            var load=$(self.wrapper).find("div.load-refresh");
            load.find("span.load-text").text("放开刷新");
            load.find("span.down-icon").addClass("up-icon");
        } else {
            var load = $(self.wrapper).find("div.load-refresh");
            load.find("span.load-text").text("下拉刷新");
            load.find("span.down-icon").removeClass("up-icon");
        }
        ///修复代码
        if ((self.y <= self.maxScrollY) && (self.pointY < 45) && self.options.border) {
            self.options.border = false;
            self.scrollTo(0, self.maxScrollY, 400);
            setTimeout(function () { self.options.border = true; }, 400);
            return false;
        } else if (self.y > 0 && (self.pointY > window.innerHeight - 1) && self.options.border) {
            self.options.border = false;
            self.scrollTo(0, 0, 400);
            setTimeout(function () { self.options.border = true; }, 400);
            return false;
        }
    
    };
    

      html代码结构如下:

    <section class="s-content" id="scroller">
            <div class="scroller">
                 <div class="load-refresh" style="background-color: transparent;">
                    <span class="down-icon"></span><span class="load-text">下拉刷新</span>
                </div>
                <ul class="text-list" >
                </ul>
                 <div class="load-more">
                      <span class="down-icon"></span><span>上拉加载更多</span> 
                 </div> 
           </div>
     </section >
    

      

       js代码:

    //border用于判断是否复原到顶部或底部,用于避免多次触发。
    document.body.onload = function () {
                var option = { probeType: 1, mouseWheel: true, fadeScrollbars: false, click: true, tap: true, border: true };
                myScroll = new IScroll('#scroller', option);
                document.addEventListener('touchmove', function (e) { e.preventDefault(); }, false);
                myScroll.on("scroll", scrollbug);
                myScroll.on("slideDown", function () {
                    var self = this;
                    if (self.y > 50) {
                        var load = $(self.wrapper).find("div.load-refresh");
                        self.scrollTo(0, 50);
                        setTimeout(function () { load.find("span.down-icon").addClass("load-icon"); }, 150);
                        $("#page-content").addClass("loading");
                        setTimeout(function () { load.find("span.load-text").text("加载中,请稍后..."); }, 100);
                        window.location.reload(true);
                    }
                });
                       myScroll.on("slideUp", function () {
                  var self = this;
               if (self.maxScrollY - self.y > 50) {
                                     var bottom = +self.maxScrollY, load = $(self.wrapper).find("div.load-more");
                  var pages = $("#activity-list").attr("data-page");
                 if (pages != "ok") {//pages 页码如果是ok这表示是最后一页
                   self.scrollTo(0, bottom - 50);
                   load.find("span.down-icon").addClass("load-icon");
                   $("body").addClass("loading");
                   setTimeout(function () { load.find("span.load-text").text("加载中,请稍后..."); }, 100);
                   pages = pages ? pages : 1;
                   toPage({ pageNO: ++pages });
                 }
               }
                      });
    
            };
    

      css样式:

    .s-content{
         position:relative;
         overflow:hidden;
          100%;
       -ms-touch-action: none;
       z-index:999999; 
       -webkit-transform: translate3d(0,0,0);
       transform: translate3d(0,0,0);
        -webkit-touch-callout: none;
        -webkit-user-select: none;
        -moz-user-select: none;
        -ms-user-select: none;user-select: none;
        -webkit-text-size-adjust: none;
        -moz-text-size-adjust: none;
        -ms-text-size-adjust: none;
        -o-text-size-adjust: none; 
        text-size-adjust: none;
    }
    .scroller {
        position: absolute;
         100%;
        -webkit-tap-highlight-color: rgba(0,0,0,0);
        -webkit-transform: translateZ(0);
        -moz-transform: translateZ(0);
        -ms-transform: translateZ(0);
        -o-transform: translateZ(0);
        transform: translateZ(0);
        -webkit-touch-callout: none;
        -webkit-user-select: none; 
        -moz-user-select: none;
        -ms-user-select: none;
        user-select: none;
        -webkit-text-size-adjust: none;
        -moz-text-size-adjust: none;
        -ms-text-size-adjust: none;
        -o-text-size-adjust: none;
        text-size-adjust: none;
        z-index:1;
        -webkit-transform: translate3d(0,0,0);
        transform: translate3d(0,0,0); 
    }
