如何使用datepicker获取日期并通过GET传递？ [英] How to get date with datepicker and pass via GET?
问题描述
我有通过GET url传递日期参数的问题。我从两个与它相关联的日期戳的输入字段中获取数据。
这里是代码：
I have problem passing date parameters via GET url. I fetch data from two input fields with datepicker associated to it. Here is code:
$(".options input[type='submit']").click(function() {
$('#From').datepicker();
$('#To').datepicker();
var $From = $('#From').datepicker('getDate').getDate();
var $To = $('#To').datepicker('getDate').getDate();
$('#placeholder').html('<img src="php/jpgraph/example2.php?From=' + $From + '&To=' + $To + '" />');
});
Html页面：
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<link rel="stylesheet" href="layout.css" type="text/css"/>
<link rel="stylesheet" href="jquery-ui-1.8.17.custom.css" type="text/css" />
<script type="text/javascript" src="jquery.js"></script>
<script type="text/javascript" src="jquery-ui.js"></script>
<script type="text/javascript" src="newjavascript.js"></script>
</head>
<body>
<div id="container">
<div id="sidemenu">
<div class="options">
Датум од:<input type="text" id="From" name="From" size="10"/><br />
Датум до:<input type="text" id="To" name="To" size="10"/>
</div>
<br />
<div class="options">
<input type="submit" value="Show">
</div>
</div>
<div id="content">
<div id="placeholder" style="width:600px;height:300px;"></div>
</div>
</div><!-- divContainer -->
</body>
</html>
当我从datepicker图像显示时选择日期。但是，如果我不选择datepicker的日期，那么没有显示。也许我可以检查是否选择日期，然后将值设置为空字符串。如下所示：
When I choose date from datepicker image shows. But if I don't choose date with datepicker then nothing shows. Maybe I could examine if date is not choosen, then to set values to empty string. Something like this:
if ($From == null) {
$From = '';
}
if ($To == null) {
$To = '';
}
我尝试过这个，但它不起作用。什么可以解决问题？
I tried this but it doesn't work. What could be solution for problem?
编辑：现在，我不在服务器端处理GET参数，以简化问题，但是请看看：
For now, I don't handle GET params on the server side, to simplify problem, but take a look:
<?php
require_once ('jpgraph.php');
require_once ('jpgraph_line.php');
$con = mysql_connect("localhost", "user", "pass");
if (!$con) {
die('Could not connect:' . mysql_error());
}
mysql_select_db("db", $con);
$result = mysql_query("select Temperature from TEMPERATURE");
$niz = array();
while ($row = mysql_fetch_array($result)) {
$niz[] = $row['Temperature'];
}
$graph = new Graph(600,400);
$graph->SetScale('intint');
$graph->title->set('Title');
$graph->xaxis->title->Set('Day');
$graph->yaxis->title->Set('Temp');
$lineplot=new LinePlot($niz);
$lineplot->SetColor('blue');
$graph->Add($lineplot);
$graph->Stroke();
?>
推荐答案
尝试这个。
if($('#From').val()){
//Get the date here
var fromDate = $('#From').datepicker('getDate');
}
if($('#To').val()){
//Get the date here
var toDate = $('#To').datepicker('getDate');
}
