JAVA实现按时间段查询数据操作

html / jsp

<span style="vertical-align: -webkit-baseline-middle;font-size:16px;font-weight:bold;">开始时间:</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;">结束时间:&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="查询" 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, // 处室ID来源于默认(页面传值)和下拉框选择 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("查询数据失败")

}

});

}

补充知识:Java 实现判断时间是否在某个区间内(如是否在23点到凌晨4点之间)

最近遇到一个需求,就是判断一个时间是否在23点到凌晨4点之间,这个时间段是可以修改的。在网上收了一下发现没有符合我的需求的,就自己琢磨了一下,感觉这样算还是可以的。

思路:

如上图的那个圆形的钟表,可以从开始时间剪断,把钟表的环铺平,此时就变成了一个刻度尺,这样就好比较了

代码块

测试代码:

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);

}

}

输出:

0 1 5

0 2 5

0 3 5

0 4 5

0 5 5

0 6 5

0 7 5

0 8 5

0 9 5

0 10 5

0 11 5

0 12 5

0 13 5

0 14 5

0 15 5

0 16 5

0 17 5

0 18 5

0 19 5

0 20 5

0 21 5

0 22 5

0 23 5

0 0 5
