js插件dropload上拉下滑加载数据实例解析
本文实例为大家分享了dropload插件上拉下滑加载数据的具体代码，供大家参考，具体内容如下
效果图：
1.导入js
dropload.min.js
zepto.min.js <!-- jQuery1.7以上 或者 Zepto 二选一，不要同时都引用 -->
2.后台查询
/**
* 我找的
*
* @return
*/
@Action("IFindTicket")
public String IFindTicket() {
try {
FuTransaction transaction = fuTransactionService.findByUserId(userId);
Map<String, Object> map = new HashMap<String, Object>();
map.put("transactionId", transaction == null ? 0L : transaction.getId());
List<FuStockAccount> accounts = fuStockAccountService.findAccountByMap(0, 5, map);
this.getActionContext().put("accounts", accounts);
} catch (Exception e) {
e.printStackTrace();
logger.equals(e);
}
return SUCCESS;
}
/**
* 我找的皇
*
* @return
*/
@Action("findTicketData")
public String findTicketData() {
try {
FuTransaction transaction = fuTransactionService.findByUserId(userId);
Map<String, Object> map = new HashMap<String, Object>();
map.put("transactionId", transaction == null ? 0L : transaction.getId());
List<FuStockAccount> accounts = fuStockAccountService.findAccountByMap(0, Integer.MAX_VALUE, map);
JSONObject json = new JSONObject();
JSONArray array = new JSONArray();
if (accounts.size() > 0) {
for (FuStockAccount account : accounts) {
JSONObject obj = new JSONObject();
obj.put("id", account.getId());
obj.put("openEquity", account.getOpenEquity());
obj.put("capitalAccount", account.getCapitalAccount());
obj.put("transactionStatus", account.getTransactionStatus());
obj.put("status", account.getTransactionStatus() == 0 ? "正在操作" : "已退");
obj.put("available", new DecimalFormat("#,###,##0.00").format(account.getAvailable() == null ? 0 : account.getAvailable()));
obj.put("ableMoney", new DecimalFormat("#,###,##0.00").format(account.getAbleMoney() == null ? 0 : account.getAbleMoney()));
obj.put("createTime", new SimpleDateFormat("yyyy.MM.dd").format(account.getCreateTime()));
array.add(obj);
}
}
json.put("array", array);
write(json.toString());
} catch (Exception e) {
e.printStackTrace();
logger.error(e);
}
return null;
} 3.页面插件的使用
