我是Javascript /客户端编程的新手但是我从所有关于JQuery UI的datepicker的帖子中了解到,datepicker的altfield将填充与datepicker相同的值,而无需创建函数在更改或选择时填充它。但是,我已为我拥有的2个日期选择器设置了我的altfield,但它们没有填充或我缺少一些配置。代码如下......
dates.js:
$(document).ready(function() {
// Datepicker Popups calender to Choose date.
$(function() {
$("#datepicker1").datepicker({
altField : "dbBegDate",
altFormat : "yy-mm-dd" }
);
$("#datepicker1").datepicker("setDate", "-1d");
$("#datepicker2").datepicker({
altField : "dbEndDate",
altFormat : "yy-mm-dd" }
);
$("#datepicker2").datepicker("setDate", "0d");
});
的index.html:
<!doctype html>
<html lang="us">
<head>
<meta charset="utf-8">
<title>BES Bad Bucket Report Date Selection</title>
<link href="./css/jquery-ui.css" rel="stylesheet">
<link href="./css/mydatepicker.css" rel="stylesheet">
<style>...
<body>
<div class="container">
<h2>Bad Bucket Report Dates Selector</h2>
<div class="main">
<form action="index.jsp" method="post">
<label>Beginning Date :</label>
<input type="text" name="beg_date" id="datepicker1"/>
<!-- <input type="hidden" id="dbBegDate" name="dbBegDate"/>-->
<input type="text" id="dbBegDate" name="dbBegDate"/>
<label>Ending Date :</label>
<input type="text" name="end_date" id="datepicker2"/>
<input type="hidden" id="dbEndDate" name="dbEndDate"/>
<input type="submit" id="submit" value="Submit">
</div>
</div>
</body>
</html>
当我尝试从index.jsp中的altfields获取日期时,它是一个空值。 datepicker值返回有效的选定日期
答案 0 :(得分:0)
定义了JQuery UI API:
altField :类型:选择器或jQuery或Element; 默认值:“”
因此,您可以使用“#”匹配元素ID,例如altField : "#dbBegDate"
。
修复此问题后,下面的代码工作。
$(document).ready(function() {
// Datepicker Popups calender to Choose date.
$("#datepicker1").datepicker({
altField : "#dbBegDate",
altFormat : "yy-mm-dd"
});
$("#datepicker1").datepicker("setDate", "-1d");
$("#datepicker2").datepicker({
altField : "#dbEndDate",
altFormat : "yy-mm-dd"
});
$("#datepicker2").datepicker("setDate", "0d");
});
