• Anchor锚点布局


      Ext.layout.container.Anchor是根据容器大小为其所包含的子面板进行定位的布局,对应面板布局配置项Anchor。

      1、百分比(Percentage)定位

      代码:

    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
    <html xmlns="http://www.w3.org/1999/xhtml">
    <head runat="server">
        <title>Ext.layout.container.Anchor示例</title>
        <link href="ext-4.0.7-gpl/resources/css/ext-all.css" rel="stylesheet" type="text/css" />
        <script src="ext-4.0.7-gpl/bootstrap.js" type="text/javascript"></script>
        <script type="text/javascript">
            Ext.onReady(function () {
                Ext.create("Ext.panel.Panel", {
                    title: "Ext.layout.container.Anchor示例",
                    frame: true,
                     300,
                    height: 200,
                    renderTo: Ext.getBody(),
                    bodyPadding: 5,
                    layout: "anchor",
                    defaults: {
                        bodyStyle: "background-color:#FFFFFF"
                    },
                    items: [{
                        anchor: "80% 50%", // 第一项宽度百分比,第二项高度百分比
                        title: "子面板"
                    }]
                });
            });
        </script>
    </head>
    <body>
    </body>
    </html>

      效果图:

      2、偏移定位

      代码:

    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
    <html xmlns="http://www.w3.org/1999/xhtml">
    <head runat="server">
        <title>Ext.layout.container.Anchor示例</title>
        <link href="ext-4.0.7-gpl/resources/css/ext-all.css" rel="stylesheet" type="text/css" />
        <script src="ext-4.0.7-gpl/bootstrap.js" type="text/javascript"></script>
        <script type="text/javascript">
            Ext.onReady(function () {
                Ext.create("Ext.panel.Panel", {
                    title: "Ext.layout.container.Anchor示例",
                    frame: true,
                     300,
                    height: 200,
                    renderTo: Ext.getBody(),
                    bodyPadding: 5,
                    layout: "anchor",
                    defaults: {
                        bodyStyle: "background-color:#FFFFFF"
                    },
                    items: [{
                        anchor: "-10 -50",
                        title: "子面板"
                    }]
                });
            });
        </script>
    </head>
    <body>
    </body>
    </html>

      3、参考边(Sides)定位

      代码:

    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
    <html xmlns="http://www.w3.org/1999/xhtml">
    <head runat="server">
        <title>Ext.layout.container.Anchor示例</title>
        <link href="ext-4.0.7-gpl/resources/css/ext-all.css" rel="stylesheet" type="text/css" />
        <script src="ext-4.0.7-gpl/bootstrap.js" type="text/javascript"></script>
        <script type="text/javascript">
            Ext.onReady(function () {
                Ext.create("Ext.panel.Panel", {
                    title: "Ext.layout.container.Anchor示例",
                    frame: true,
                     300,
                    height: 200,
                    renderTo: Ext.getBody(),
                    bodyPadding: 5,
                    layout: "anchor",
                    defaults: {
                        bodyStyle: "background-color:#FFFFFF"
                    },
                    items: [{
                        anchor: "r b", // r:right b:bottom
                         200,
                        height: 100,
                        title: "子面板"
                    }]
                });
            });
        </script>
    </head>
    <body>
    </body>
    </html>
