当使用jQWidgets库的jqxScheduler控件来创建日程表时,我们可以通过设置控件的appointmentOpacity属性来改变日程表的不透明度,从而实现更好的视觉效果。下面是关于该属性的详细攻略:
appointmentOpacity属性的定义和用法
appointmentOpacity属性指定了日程表中所有预约的不透明度(透明度)。该属性可设置的值为0到1之间的数字,其中0表示完全透明,1表示完全不透明,0.5表示50%不透明。默认值为1(完全不透明)。
设置appointmentOpacity属性:
$("#scheduler").jqxScheduler({
appointmentOpacity: 0.5
});
示例1:将所有预约的不透明度设置为0.5
在以下示例中,我们将创建一个日程表,并将所有预约的不透明度设置为0.5。下面是完整的HTML和JavaScript代码:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<title>jqxScheduler - Appointment Opacity Example</title>
<link rel="stylesheet" href="https://jqwidgets.com/public/jqwidgets/styles/jqx.base.css" />
<link rel="stylesheet" href="https://jqwidgets.com/public/jqwidgets/styles/jqx.energyblue.css" />
<script type="text/javascript" src="https://jqwidgets.com/public/jqwidgets/jqx-all.js"></script>
</head>
<body>
<div id="scheduler"></div>
<script>
$(document).ready(function () {
//创建日程表
$("#scheduler").jqxScheduler({
//设置appointmentOpacity属性为0.5
appointmentOpacity: 0.5,
width: 600,
height: 600
});
});
</script>
</body>
</html>
运行上面的代码,可以看到日程表上所有的预约的不透明度变为了0.5。可以尝试调整appointmentOpacity属性的值,看看不同的值所产生的效果。
示例2:将某个预约的不透明度设置为0.3
在此示例中,我们将创建一个日程表,并将特定的预约(ID为6)的不透明度设置为0.3,其他预约的不透明度仍为1。下面是完整的HTML和JavaScript代码:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<title>jqxScheduler - Appointment Opacity Example</title>
<link rel="stylesheet" href="https://jqwidgets.com/public/jqwidgets/styles/jqx.base.css" />
<link rel="stylesheet" href="https://jqwidgets.com/public/jqwidgets/styles/jqx.energyblue.css" />
<script type="text/javascript" src="https://jqwidgets.com/public/jqwidgets/jqx-all.js"></script>
</head>
<body>
<div id="scheduler"></div>
<script>
$(document).ready(function () {
//创建日程表
$("#scheduler").jqxScheduler({
width: 600,
height: 600,
//设置特定预约的不透明度
source: {
dataType: "array",
dataFields: [
{ name: "id", type: "string" },
{ name: "subject", type: "string" },
{ name: "description", type: "string" },
{ name: "location", type: "string" },
{ name: "start", type: "date" },
{ name: "end", type: "date" },
{ name: "color", type: "string" }
],
localData: [
{
id: "1", subject: "Test Appointment 1", start: new Date(2021, 2, 20, 10, 0, 0), end: new Date(2021, 2, 20, 12, 0, 0), color: "#fcb322"
},
{
id: "2", subject: "Test Appointment 2", start: new Date(2021, 2, 20, 14, 0, 0), end: new Date(2021, 2, 20, 16, 0, 0), color: "#9d9dff"
},
{
id: "3", subject: "Test Appointment 3", start: new Date(2021, 2, 20, 10, 0, 0), end: new Date(2021, 2, 20, 12, 0, 0), color: "#00af00"
},
{
id: "4", subject: "Test Appointment 4", start: new Date(2021, 2, 21, 10, 0, 0), end: new Date(2021, 2, 21, 13, 0, 0), color: "#fcb322"
},
{
id: "5", subject: "Test Appointment 5", start: new Date(2021, 2, 21, 14, 0, 0), end: new Date(2021, 2, 21, 16, 0, 0), color: "#9d9dff"
},
{
id: "6", subject: "Test Appointment 6", start: new Date(2021, 2, 21, 12, 0, 0), end: new Date(2021, 2, 21, 15, 0, 0), color: "#00af00"
}
]
},
//使用appointmentRenderer回调函数设置特定预约的不透明度
appointmentRenderer: function (data) {
if (data.id === "6") {
data.opacity = 0.3;
}
}
});
});
</script>
</body>
</html>
运行上面的代码,可以看到日程表上特定预约的不透明度变为了0.3,其他预约的不透明度保持不变。
总结:通过设置jqxScheduler控件的appointmentOpacity属性,我们可以轻松地改变日程表上所有预约的不透明度,从而改变日程表的视觉效果。同时,我们还可以使用appointmentRenderer回调函数来改变特定预约的不透明度,使日程表更易于浏览。
