jQWidgets jqxResponsivePanel refresh()方法详解

什么是jQWidgets jqxResponsivePanel refresh()方法

jqxResponsivePaneljQWidgets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.jsjqxresponsivepanel.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>

    <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。
