Friends in need can For reference, I hope it will be helpful to everyone.

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

##The first usage example of the 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>p class="demo">
<</SPAN>p>Date:<</SPAN>input type="text" id="datepicker"></</SPAN>p>
</</SPAN>p>

Then use the js code to call the plug-in

Screenshot of the effect ：

The following is to verify some common attributes through examples:

1, altField:Use the alternate output field, which is about to be selected The date is output to another control in another format, and the value is the selector, that is, the control to be output

altFormat: format of altField output

Instance verification:

Page code:

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

##Js code:

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

Effect screenshot:

2. showAnim:

Set the animation name for displaying or hiding the date panel Writing of js code:

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

3. showButtonPanel:

Whether Display button panelJs code:

$( "#datepicker" ).datepicker({
showButtonPanel:true
});

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

4. dateFormat:

Specify the format for displaying the date Js code:

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

Effect screenshot:

As you can see from the image, the date format in the text box has 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 monthchangeYear: whether to use the drop-down list to select the yearAdd this attribute in the 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. It 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 the js code:

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

Effect Screenshot:

From the picture, you can see that the position of the year is in the form of a drop-down menu, in which 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. It can be an array containing two numbers, indicating the number of rows and columns displayed Js code:

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

Specify numberOfMonths as 3 above, then the pop-up calendar panel will display the current and next two months , as shown in the picture:

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）：
