這篇文章主要介紹了JAVA實(shí)現(xiàn)按時(shí)間段查詢數(shù)據(jù)操作，具有很好的參考價(jià)值，希望對(duì)大家有所幫助。一起跟隨小編過(guò)來(lái)看看吧

html / jsp

<span style="vertical-align: -webkit-baseline-middle;font-size:16px;font-weight:bold;">開(kāi)始時(shí)間：</span>&nbsp; 
<input name="startTime" id="startTime" type="text" class="Wdate" onfocus="WdatePicker()" style="height: 34px;
 line-height: 34px; border-radius: 4px; border: 1px solid #ccc; font-size: 14px;">
<span class="ml10 mr8" style="font-size:16px;font-weight:bold;">結(jié)束時(shí)間：&nbsp;</span>
<input name="endTime" id="endTime" type="text" class="Wdate" onfocus="WdatePicker()" style="height: 34px;
 line-height: 34px; border-radius: 4px; border: 1px solid #ccc; font-size: 14px;">
<input type="submit" class="btn btn-query" id="findTime" value="查詢" onClick="toFindTime();" style="float:none;"/>

js方法：

function timeCheckInfo(page,startTime,endTime,officeVal){
 var startTime=$("#startTime").val();
 var endTime=$("#endTime").val();
 $.ajax({
 url: "../../security/base/peoplesafeimg!findPortFolioByTime.action",
 type: "post",
 data:{
  pagenum:page,
  startTime:startTime,
  endTime:endTime,
  deptid:officeid, // 處室ID來(lái)源于默認(rèn)(頁(yè)面?zhèn)髦?和下拉框選擇 lenian 2018 06 29
  depotid:depotid
 },
 dataType: "json",
 success: function (data) {
  //alert(JSON.stringify(data));
  var dataset = data[0].result;
  $(dataset).each(function(i,val) {
  
  });
 },
 error:function(){
  alert("查詢數(shù)據(jù)失敗")
 }
 }); 
}

補(bǔ)充知識(shí)：Java 實(shí)現(xiàn)判斷時(shí)間是否在某個(gè)區(qū)間內(nèi)（如是否在23點(diǎn)到凌晨4點(diǎn)之間）

最近遇到一個(gè)需求，就是判斷一個(gè)時(shí)間是否在23點(diǎn)到凌晨4點(diǎn)之間，這個(gè)時(shí)間段是可以修改的。在網(wǎng)上收了一下發(fā)現(xiàn)沒(méi)有符合我的需求的，就自己琢磨了一下，感覺(jué)這樣算還是可以的。

思路：

如上圖的那個(gè)圓形的鐘表，可以從開(kāi)始時(shí)間剪斷，把鐘表的環(huán)鋪平，此時(shí)就變成了一個(gè)刻度尺，這樣就好比較了

代碼塊

測(cè)試代碼：

public static void main(String[] args) {
  int start = 23;
  int end = 4;

  int emp = 24 - start;

  for (int d = 0; d < 24; d++) {
    System.out.println((start + emp) % 24 + "\t" + (d + emp) % 24 + "\t" + (end + emp) % 24);
  }
}

輸出：

以上這篇JAVA實(shí)現(xiàn)按時(shí)間段查詢數(shù)據(jù)操作就是小編分享給大家的全部?jī)?nèi)容了，希望能給大家一個(gè)參考，也希望大家多多支持腳本之家。
