根据开始日期和结束日期筛选JSON
Filter JSON based on startdate and enddate
我的JSON如下所示：

JSON来自外部来源，在生产中是动态的，但所有来源都具有相同的结构。
用户将有三个输入：
- 选择JSON源的第一个输入（出于演示目的删除）
- 选择开始日期以开始返回JSON数据的第二个输入（例如2015-06-01）
- 选择结束日期以结束返回JSON数据的第三个输入（例如2015-06-19）
这是表单HTML:
<div class="row">
<form id="search" role="form" style="border:0">
<div class="col-md-3">
<ul class="nav nav-stacked">
<li><strong>From Date</strong></li>
<li>
<input type="text" class="form-control" placeholder="yyyy-mm-dd" id="dateFrom" />
</li>
</ul>
</div>
<div class="col-md-3">
<ul class="nav nav-stacked">
<li><strong>To Date</strong></li>
<li>
<input type="text" class="form-control" placeholder="yyyy-mm-dd" id="dateTo" />
</li>
</ul>
</div>
<div class="col-md-3">
<ul class="nav nav-stacked">
<li> </li>
<li>
<button class="btn btn-primary" type="button" id="getJsonSrc">Search</button>
</li>
</ul>
</div>
</form>
</div>
<!-- Row -->
这是javascript：
$("#getJsonSrc").click(function() {
var $table = $("#dataTable"),
$startDate = $("#dateFrom").val(),
$endDate = $("#dateTo").val(),
$jsonSrc = "https://s3-us-west-2.amazonaws.com/s.cdpn.io/77979/demo.json"; //for demo only - in production this will come from 1st input val()
/* This is the code that is not working */
$jsonSrc = filter(function(i, fromDate, toDate) {
return ($jsonSrc.date < $startDate && $jsonSrc.date > $endDate)
});
$table.bootstrapTable("destroy");
$table.bootstrapTable();
$table.bootstrapTable("refresh", {
url: $jsonSrc
});
});
本质上，我想要的是当用户点击搜索时，页面会获得JSON源URL，但只返回输入日期之间的数据（包括输入日期）。JSON随后被输出到引导数据表中。
我通常提供一个jsFiddle示例，但是我没有办法让fiddle读取外部JSON文件，所以希望代码笔示例可以：）
http://codepen.io/lordtubington/pen/GJOVpy
注意：我意识到引导表有一个过滤器扩展https://github.com/lukaskral/bootstrap-table-filter然而，这个过滤器扩展在数据被提取之后工作。我的用户将请求包含数千条记录的文件，我不能让他们获取所有记录，然后应用日期过滤器：）
我通过以下方式修复了代码：
http://codepen.io/anon/pen/pJdMxv
我所做的更改：我通过jquery加载json，为开始日期、结束日期和obj日期创建日期对象，然后创建一个新的Array，并在数组中推送所有匹配的日期。
$("#getJsonSrc").click(function() {
var $table = $("#dataTable"),
$startDate = new Date($("#dateFrom").val()),
$endDate = new Date($("#dateTo").val()),
$jsonSrc = "https://s3-us-west-2.amazonaws.com/s.cdpn.io/77979/demo.json";
$.getJSON($jsonSrc).success(function(data) {
my_array = new Array();
for (var i = 0; i < data.length; i++) {
var this_date = new Date(data[i].date);
if ((this_date >= $startDate) && (this_date <= $endDate)) {
my_array.push(data[i]);
}
}
console.log(my_array);
$table.bootstrapTable("destroy");
$table.bootstrapTable();
$table.bootstrapTable("refresh", {
url: my_array
});
});
});
原来我不需要JSON.stringify(my_array)，我需要使用load选项而不是data。以下是工作代码：
$("#getJsonSrc").click(function() {
$("#dataTable thead").show();
var $table = $("#dataTable"),
$startDate = new Date($("#dateFrom").val()),
$endDate = new Date($("#dateTo").val()),
$jsonSrc = "https://s3-us-west-2.amazonaws.com/s.cdpn.io/77979/demo.json";
var my_array;
$.getJSON($jsonSrc).success(function(data) {
my_array = [];
for (var i = 0; i < data.length; i++) {
var this_date = new Date(data[i].date);
if ((this_date >= $startDate) && (this_date <= $endDate)) {
my_array.push(data[i]);
}
}
$table.bootstrapTable("load", my_array);
});
