JQuery插件:iScroll
页面布局:
<div id="wrapper">
<div id="scroller">
<div id="pullDown">
<span class="pullDownIcon"></span><span class="pullDownLabel">下拉刷新...</span>
</div>
<ul id="thelist">
<li>
<img src="/UploadFiles/2021-04-02/page1_img1.jpg">
翻页,是通过ajax请求,把页码传入一般处理程序,在一般处理程序中获得分页后的数据返回json数组对象。
下拉刷新:
/**
* 下拉刷新 (自定义实现此方法)
* myScroll.refresh(); // 数据加载完成后,调用界面更新方法
*/
function pullDownAction() {
setTimeout(function () {
var el, li, i;
el = document.getElementById('thelist');
//==========================================
$.ajax({
type: "GET",
url: "LoadMore.ashx",
data: { page: generatedCount },
dataType: "json",
success: function (data) {
var json = data;
$(json).each(function () {
li = document.createElement('li');
// li.innerText = 'Generated row ' + (++generatedCount);
li.innerHTML = '<img src="/UploadFiles/2021-04-02/' + this.src + '">

RTX 5090要首发 性能要翻倍!三星展示GDDR7显存
三星在GTC上展示了专为下一代游戏GPU设计的GDDR7内存。
首次推出的GDDR7内存模块密度为16GB,每个模块容量为2GB。其速度预设为32 Gbps(PAM3),但也可以降至28 Gbps,以提高产量和初始阶段的整体性能和成本效益。
据三星表示,GDDR7内存的能效将提高20%,同时工作电压仅为1.1V,低于标准的1.2V。通过采用更新的封装材料和优化的电路设计,使得在高速运行时的发热量降低,GDDR7的热阻比GDDR6降低了70%。
