jQWidgets jqxResponsivePanel refresh()方法详解
什么是jQWidgets jqxResponsivePanel refresh()方法
jqxResponsivePanel
是jQWidgets
中的一种插件,它提供了响应式面板,可以根据父元素的大小来动态调整内部元素的布局和大小,以实现不同设备的优美显示。
refresh()
方法是jqxResponsivePanel
插件中的一种方法,用于重新计算并调整面板内元素的布局以配合父元素的变化。
refresh()方法的语法和参数
refresh()
方法的语法如下:
$("#jqxResponsivePanel").jqxResponsivePanel("refresh");
该方法没有参数。
refresh()方法的调用
因为refresh()
方法是jqxResponsivePanel
插件中的方法,所以在使用该方法之前,需要先加载jqxcore.js
、jqxresponsivepanel.js
和相应的CSS文件。
例如,在HTML文件的head
标签中添加以下代码:
<link rel="stylesheet" href="https://jqwidgets.com/public/jqwidgets/styles/jqx.base.css" type="text/css" />
<link rel="stylesheet" href="https://jqwidgets.com/public/jqwidgets/styles/jqx.material-blue.css" type="text/css" />
<script src="https://jqwidgets.com/public/jqwidgets/jqxcore.js" type="text/javascript"></script>
<script src="https://jqwidgets.com/public/jqwidgets/jqxresponsivepanel.js" type="text/javascript"></script>
然后,在HTML文件中添加响应式面板,例如:
<div id="jqxResponsivePanel">
<div class="jqx-responsive-panel-header">
<div class="jqx-responsive-panel-hamburger">
<div></div>
<div></div>
<div></div>
</div>
<div class="jqx-responsive-panel-title">jqxResponsivePanel</div>
</div>
<div class="jqx-responsive-panel-content">
<div class="jqx-responsive-panel-item">
This is item 1.
</div>
<div class="jqx-responsive-panel-item">
This is item 2.
</div>
<div class="jqx-responsive-panel-item">
This is item 3.
</div>
</div>
</div>
最后,在JavaScript中调用refresh()
方法,例如:
$("#jqxResponsivePanel").jqxResponsivePanel("refresh");
refresh()方法的示例说明
示例 1:在窗口大小改变时调用refresh()方法
在这个示例中,我们创建一个响应式面板并将其添加到HTML页面中,然后当窗口大小改变时调用refresh()
方法。
<!DOCTYPE html>
<html>
<head>
<title>refresh()方法示例1</title>
<link rel="stylesheet" href="https://jqwidgets.com/public/jqwidgets/styles/jqx.base.css" type="text/css" />
<link rel="stylesheet" href="https://jqwidgets.com/public/jqwidgets/styles/jqx.material-blue.css" type="text/css" />
<script src="https://jqwidgets.com/public/jqwidgets/jqxcore.js" type="text/javascript"></script>
<script src="https://jqwidgets.com/public/jqwidgets/jqxresponsivepanel.js" type="text/javascript"></script>
</head>
<body>
<div id="container">
<div id="jqxResponsivePanel">
<div class="jqx-responsive-panel-header">
<div class="jqx-responsive-panel-hamburger">
<div></div>
<div></div>
<div></div>
</div>
<div class="jqx-responsive-panel-title">jqxResponsivePanel</div>
</div>
<div class="jqx-responsive-panel-content">
<div class="jqx-responsive-panel-item">
This is item 1.
</div>
<div class="jqx-responsive-panel-item">
This is item 2.
</div>
<div class="jqx-responsive-panel-item">
This is item 3.
</div>
</div>
</div>
</div>
<script>
$(document).ready(function () {
// 初始化响应式面板
$("#jqxResponsivePanel").jqxResponsivePanel({
width: 300,
height: 400
});
// 窗口大小改变时调用refresh()方法
$(window).resize(function () {
$("#jqxResponsivePanel").jqxResponsivePanel("refresh");
});
});
</script>
</body>
</html>
在上面的示例中,当窗口大小改变时,我们调用了resize
事件并在其中调用了refresh()
方法。
示例 2:在添加和删除面板项目时调用refresh()方法
在这个示例中,我们创建一个响应式面板并将3个面板项目添加到其中,然后在添加或删除面板项目时,调用refresh()
方法。
<!DOCTYPE html>
<html>
<head>
<title>refresh()方法示例2</title>
<link rel="stylesheet" href="https://jqwidgets.com/public/jqwidgets/styles/jqx.base.css" type="text/css" />
<link rel="stylesheet" href="https://jqwidgets.com/public/jqwidgets/styles/jqx.material-blue.css" type="text/css" />
<script src="https://jqwidgets.com/public/jqwidgets/jqxcore.js" type="text/javascript"></script>
<script src="https://jqwidgets.com/public/jqwidgets/jqxresponsivepanel.js" type="text/javascript"></script>
</head>
<body>
<div id="container">
<div id="jqxResponsivePanel">
<div class="jqx-responsive-panel-header">
<div class="jqx-responsive-panel-hamburger">
<div></div>
<div></div>
<div></div>
</div>
<div class="jqx-responsive-panel-title">jqxResponsivePanel</div>
</div>
<div class="jqx-responsive-panel-content">
<div class="jqx-responsive-panel-item">
This is item 1.
</div>
<div class="jqx-responsive-panel-item">
This is item 2.
</div>
<div class="jqx-responsive-panel-item">
This is item 3.
</div>
</div>
</div>
<br />
<button id="add-item">添加项目</button>
<button id="remove-item">删除项目</button>
</div>
<script>
$(document).ready(function () {
// 初始化响应式面板
$("#jqxResponsivePanel").jqxResponsivePanel({
width: 300,
height: 400
});
// 添加面板项目时调用refresh()方法
$("#add-item").click(function () {
$("<div>", {
class: "jqx-responsive-panel-item",
text: "This is a new item"
}).appendTo(".jqx-responsive-panel-content");
$("#jqxResponsivePanel").jqxResponsivePanel("refresh");
});
// 删除面板项目时调用refresh()方法
$("#remove-item").click(function () {
$(".jqx-responsive-panel-content div:last-child").remove();
$("#jqxResponsivePanel").jqxResponsivePanel("refresh");
});
});
</script>
</body>
</html>
在上面的示例中,我们分别通过“添加项目”和“删除项目”按钮,调用了click
事件并在其中添加或删除面板项目,并在每次修改后调用了refresh()
方法。
