jQWidgets jqxScheduler是一个功能强大的日程表控件，可以用来展示和管理各种时间段的活动。其中，cellClick事件是当用户单击了日程表中的任意单元格时触发的事件。在本篇文章中，我们将详细讲解如何使用jQWidgets jqxScheduler控件的cellClick事件。
1. 安装jqwidgets
首先，我们需要在我们的项目中安装jqwidgets库，可以通过npm包管理工具进行安装：
npm install jqwidgets-scripts --save
2. 引入相关文件
在使用jQWidgets jqxScheduler控件之前，我们需要先在HTML文件中引入相关的js和css文件。具体如下：
<!-- 引入jqwidgets.css文件 -->
<link rel="stylesheet" href="./jqwidgets/styles/jqx.base.css" type="text/css" />
<!-- 引入jqwidgets js文件 -->
<script type="text/javascript" src="./jqwidgets/jqxcore.js"></script>
<script type="text/javascript" src="./jqwidgets/jqxbuttons.js"></script>
<script type="text/javascript" src="./jqwidgets/jqxscrollbar.js"></script>
<script type="text/javascript" src="./jqwidgets/jqxmenu.js"></script>
<script type="text/javascript" src="./jqwidgets/jqxgrid.js"></script>
<script type="text/javascript" src="./jqwidgets/jqxgrid.filter.js"></script>
<script type="text/javascript" src="./jqwidgets/jqxgrid.sort.js"></script>
<script type="text/javascript" src="./jqwidgets/jqxgrid.pager.js"></script>
<script type="text/javascript" src="./jqwidgets/jqxgrid.selection.js"></script>
<script type="text/javascript" src="./jqwidgets/jqxgrid.edit.js"></script>
<script type="text/javascript" src="./jqwidgets/jqxgrid.columnsresize.js"></script>
<script type="text/javascript" src="./jqwidgets/jqxdata.js"></script>
<script type="text/javascript" src="./jqwidgets/jqxdatetimeinput.js"></script>
<script type="text/javascript" src="./jqwidgets/jqxcalendar.js"></script>
<script type="text/javascript" src="./jqwidgets/jqxtooltip.js"></script>
<script type="text/javascript" src="./jqwidgets/jqxscheduler.js"></script>
<script type="text/javascript" src="./jqwidgets/jqxscheduler.api.js"></script>
3. 创建日程表
接下来，我们创建一个简单的日程表，并绑定cellClick事件。具体如下：
<!-- HTML代码 -->
<div id="scheduler"></div>
<!-- JS代码 -->
// 初始化日程表
var scheduler = $("#scheduler").jqxScheduler({
width: "100%",
height: 600,
date: new Date(),
view: "weekView",
appointmentHeight: 40,
resources:
{
colorScheme: "scheme05",
dataField: "calendar",
source: new $.jqx.dataAdapter({
dataFields: [
{ name: "id", type: "string" },
{ name: "name", type: "string" },
{ name: "color", type: "string" }
],
dataType: "array",
localData: [
{ id: "calendar1", name: "Calendar 1", color: "#f2cb1d" },
{ id: "calendar2", name: "Calendar 2", color: "#03a9f4" },
{ id: "calendar3", name: "Calendar 3", color: "#4caf50" }
]
})
},
views:
[
"dayView",
"weekView",
"monthView"
],
appointments:
[
{
description: "Meeting with John",
location: "Room 101",
subject: "Plan new project",
calendar: "calendar1",
from: new Date(2021, 11, 1, 10, 0, 0),
to: new Date(2021, 11, 121, 11, 0, 0),
},
{
description: "Meeting with Susan",
location: "Room 102",
subject: "Review current status",
calendar: "calendar2",
from: new Date(2021, 11, 7, 13, 0, 0),
to: new Date(2021, 11, 7, 14, 0, 0),
},
{
description: "Team meeting",
location: "Room 103",
subject: "Weekly sync-up",
calendar: "calendar3",
from: new Date(2021, 11, 10, 15, 0, 0),
to: new Date(2021, 11, 10, 16, 0, 0),
}
]
});
// 绑定cellClick事件
scheduler.on("cellClick", function (event) {
console.log(event.args.date);
});
上述代码中，我们使用jqxScheduler创建一个日程表，并将其绑定到页面上。然后我们通过on方法绑定了cellClick事件，并在事件处理器中打印出了事件的日期。
4. 示例说明
示例一
在这个示例中，我们将展示如何通过cellClick事件获取用户点击的单元格的信息。
<div id="scheduler"></div>
<script type="text/javascript">
// 初始化日程表
var scheduler = $("#scheduler").jqxScheduler({
width: "100%",
height: 600,
date: new Date(),
view: "weekView",
appointmentHeight: 40,
resources:
{
colorScheme: "scheme05",
dataField: "calendar",
source: new $.jqx.dataAdapter({
dataFields: [
{ name: "id", type: "string" },
{ name: "name", type: "string" },
{ name: "color", type: "string" }
],
dataType: "array",
localData: [
{ id: "calendar1", name: "Calendar 1", color: "#f2cb1d" },
{ id: "calendar2", name: "Calendar 2", color: "#03a9f4" },
{ id: "calendar3", name: "Calendar 3", color: "#4caf50" }
]
})
},
views:
[
"dayView",
"weekView",
"monthView"
],
appointments:
[
{
description: "Meeting with John",
location: "Room 101",
subject: "Plan new project",
calendar: "calendar1",
from: new Date(2021, 11, 1, 10, 0, 0),
to: new Date(2021, 11, 121, 11, 0, 0),
},
{
description: "Meeting with Susan",
location: "Room 102",
subject: "Review current status",
calendar: "calendar2",
from: new Date(2021, 11, 7, 13, 0, 0),
to: new Date(2021, 11, 7, 14, 0, 0),
},
{
description: "Team meeting",
location: "Room 103",
subject: "Weekly sync-up",
calendar: "calendar3",
from: new Date(2021, 11, 10, 15, 0, 0),
to: new Date(2021, 11, 10, 16, 0, 0),
}
]
});
// 绑定cellClick事件
scheduler.on("cellClick", function (event) {
console.log(event.args.date + " clicked.");
console.log(event.args.resource.calendar + " cell clicked.");
});
</script>
上述代码中，我们在cellClick事件的处理器中，分别使用console.log打印了事件引发的日期和点击的日程表单元格所属的资源（calendar1、calendar2或calendar3）。
示例二
在这个示例中，我们将展示如何通过cellClick事件选中事件，并将刚选择的事件设为当前事件。
<div id="scheduler"></div>
<script type="text/javascript">
// 初始化日程表
var scheduler = $("#scheduler").jqxScheduler({
width: "100%",
height: 600,
date: new Date(),
view: "weekView",
appointmentHeight: 40,
resources:
{
colorScheme: "scheme05",
dataField: "calendar",
source: new $.jqx.dataAdapter({
dataFields: [
{ name: "id", type: "string" },
{ name: "name", type: "string" },
{ name: "color", type: "string" }
],
dataType: "array",
localData: [
{ id: "calendar1", name: "Calendar 1", color: "#f2cb1d" },
{ id: "calendar2", name: "Calendar 2", color: "#03a9f4" },
{ id: "calendar3", name: "Calendar 3", color: "#4caf50" }
]
})
},
views:
[
"dayView",
"weekView",
"monthView"
],
appointments:
[
{
description: "Meeting with John",
location: "Room 101",
subject: "Plan new project",
calendar: "calendar1",
from: new Date(2021, 11, 1, 10, 0, 0),
to: new Date(2021, 11, 121, 11, 0, 0),
},
{
description: "Meeting with Susan",
location: "Room 102",
subject: "Review current status",
calendar: "calendar2",
from: new Date(2021, 11, 7, 13, 0, 0),
to: new Date(2021, 11, 7, 14, 0, 0),
},
{
description: "Team meeting",
location: "Room 103",
subject: "Weekly sync-up",
calendar: "calendar3",
from: new Date(2021, 11, 10, 15, 0, 0),
to: new Date(2021, 11, 10, 16, 0, 0),
}
]
});
// 绑定cellClick事件
scheduler.on("cellClick", function (event) {
var date = event.args.date;
var resource = event.args.resource.calendar;
scheduler.clearSelection();
scheduler.selectCell(date, resource);
var appointment = scheduler.getSelection()[0];
scheduler.scrollTo(appointment.from);
scheduler.ensureVisible(appointment);
});
</script>
上述代码中，我们在cellClick事件的处理器中，将选中的事件（即鼠标单击的事件）设为当前事件，并将其滚动到可见区域。
