How to use jquery UI Datepicker time control (enhanced version)_jquery

Let’s first take a look at the property table of the Datepicker plug-in:

The first usage example of calendar plug-in
First import the required class library files:

<</SPAN>scripttype="text/javascript" src="${pageContext.request.contextPath }/js/jquery-1.7.1.min.js"></</SPAN>script>
<</SPAN>scripttype="text/javascript" src="${pageContext.request.contextPath }/js/jquery.ui.datepicker-zh-CN.js"></</SPAN>script>
<</SPAN>scripttype="text/javascript"src="${pageContext.request.contextPath }/js/jquery-ui-1.8.18.custom.min.js"></</SPAN>script>
<</SPAN>linkrel="stylesheet"type="text/css"href="${pageContext.request.contextPath }/css/ui-lightness/jquery-ui-1.8.18.custom.css">

First write the page code:

<</SPAN>div class="demo">
<</SPAN>p>Date:<</SPAN>input type="text" id="datepicker"></</SPAN>p>
</</SPAN>div>

Then use js code to call the plug-in

Screenshot of the effect:

The following is a verification of some common attributes through examples:
1. altField: Use an alternative output field, that is, output the selected date in another format to another control, and the value is the selector, that is, the control to be output
altFormat: format of altField output
Example verification:
Page code:

<</SPAN>div class="demo">
<</SPAN>p>Date: <</SPAN>input type="text" id="datepicker">
<</SPAN>input type="text" id="alternate" size="30"/></</SPAN>p>
</</SPAN>div>

Js code:

$(function() {
$( "#datepicker" ).datepicker({
altField: "#alternate",
altFormat: "DD, d MM, yy"
});
});

Screenshot of the effect:

2. showAnim: Set the animation name displayed or hidden in the date panel
Writing js code:

$(function() {
$( "#datepicker" ).datepicker();
$( "#anim" ).change(function() {
$( "#datepicker" ).datepicker( "option", "showAnim", $( this ).val() );
});
});

3. showButtonPanel: Whether to display the button panel
Js code:
[javascript] view plaincopyprint?
$( "#datepicker" ).datepicker({
showButtonPanel:true
});

As shown in the picture, there are two buttons below the panel: clicking "Today" will jump to today's date, and clicking "Close" will close the panel.

4. dateFormat: Specify the format for displaying the date
Js code:

$( "#datepicker" ).datepicker({
dateFormat:"yy/mm/dd"
});

Screenshot of the effect:

As you can see from the image, the date format in the text box has been changed from "yy-mm-dd" to "by/mm/dd". Of course, there are other formats that can be set according to your own preferences.
5. changeMonth: Whether to use the drop-down list to select the month
changeYear: whether to use the drop-down list to select the year
Add this attribute in js code: changeMonth:true or changeYear:true
The month or year in the title bar will appear in the form of a drop-down menu:

6. yearRange: Set the year range displayed in the drop-down list box, which can be relative to this year (-nn: nn) or relative to the selected year (c-nn:c nn) or absolute year (nnnn:nnnn)
Add attributes in js code:

$( "#datepicker" ).datepicker({
changeYear: true,
yearRange:"2011:2012"
});

Screenshot of the effect:

As you can see from the picture, the position of the year is in the form of a drop-down menu, and only the options for 2011 and 2012 will appear in the drop-down menu.
Note: the yearRange attribute is only used when changeYear is true.

7. numberOfMonths: Set how many months to display at a time. Can be an array containing two numbers, indicating the number of rows and columns displayed
Js code:

$( "#datepicker" ).datepicker({
numberOfMonths: 3
});

上面指定numberOfMonths为3，那么弹出的日历面板就会显示当前以及以后两个月，如图：

8、showOn：设置触发选择器的事件名称
buttonText：指定触发按钮上显示的文本，showOn属性应设置为button或both
buttonImage：指定弹出按钮图像的URL，若设置则buttonText将成为alt值
buttonImageOnly：是否将图像放在控件后面，作为触发器，如果设置为true那么按钮将只剩下图片作为按钮，是页面更加美观
这里我编写三个文本框进行以上属性的对比：
1) Js代码：

$( "#datepicker2" ).datepicker({
showOn: "both",
buttonText:"日历按钮"
});

效果截图：

2）将按钮设置为图片：
Js代码：

$( "#datepicker" ).datepicker({
showOn: "button",
buttonImage: "images/calendar.gif",
buttonImageOnly: true
});

通过以上对比，可以理解buttonImageOnly属性的作用。
9、minDate：可以选择的最小日期，null表示无限制
maxDate：可以选择的最大日期。null表示无限制
两者都是根据以当天日期为基础的。
Js代码：

$(function() {
$( "#datepicker" ).datepicker({
//表示以当天为准，只有在20天之前和10天之后的日期之间的时间可以选择
minDate: -20,
maxDate: "+10D"
});
});

如下图在7号之前都不可选择（当前日期为27）：
