前端出现混合模式，一个站点需要手机访问和PC访问，在进行混合模式中，一个分页下拉滚动的功能是需要自己考虑的，这里有两种方法，自己开发和使用插件。为了减少开发复杂难度，插件有：iscroll 和 https://github.com/ximan/dropload，这个都是没有实验过的插件，在进行插件使用的时候，值得注意的点在于，iscroll-probe.js的插件中，有一个参数一定要注意，
//preventDefault: true,
这个参数是将A标签对应的默认事件都去除，使得A标签将会失效，如果你需要将A标签释放出来，那么，这个参数需要修改为false即可，还有一个地方需要注意，如果进行加载的时候，有出现拉下，松手后反弹的情况，那么，将异步加载的方式设置为
async: false,
效果会更好，所以，在前端的时候值得注意点的是这两个，然后附上前端部分js代码，进行使用，
