Javascript 如何使 ExtJS 表格布局具有百分比而不是高度和宽度的绝对值？

How to make an ExtJS table layout have percentage instead of absolute values for height and width?

提问by Edward Tanguay

Using Ext.Paneland the tablelayout, I was able to create a layout just the way I want. However, how do I change this code so that I can define the widths and heights proportionally?

使用Ext.Panel和table布局，我能够按照我想要的方式创建布局。但是，如何更改此代码以便可以按比例定义宽度和高度？

e.g. the table should not be 800 pixels but 100% of the screen width, and each box not 200 pixels but 25%.

例如，表格不应该是 800 像素，而是屏幕宽度的 100%，每个框不应该是 200 像素，而是 25%。

here is the code:

这是代码：

<script type="text/javascript">

    clearExtjsComponent(targetRegion);

    var table_wrapper2 = new Ext.Panel({
        id: 'table_wrapper2',
        baseCls: 'x-plain',
        renderTo: Ext.getBody(),
        layout:'table',
        layoutConfig: {columns:2},
        defaults: {
            frame:true,
            width:200,
            height: 200,
            style: 'margin: 0 10px 10px 0'
        },
        items:[{
                title:'Shopping Cart',
                width: 400,
                height: 290,
                colspan: 2
            },{
                title:'Invoice Address',
                width: 190,
                height: 100
            },{
                title:'Delivery Address',
                width: 200,
                height: 100
            }
        ]
    })

    var table_wrapper = new Ext.Panel({
        id:'table_wrapper',
        baseCls:'x-plain',
        renderTo: Ext.getBody(),
        layout:'table',
        layoutConfig: {columns:4},
        defaults: {
            frame:true,
            width:200,
            height: 200,
            style: 'margin: 10px 0 0 10px'
        },
        items:[{
                title:'Orders',
                width: 810,
                colspan: 4
            },{
                title:'Customer Information',
                width: 400,
                height: 400,
                colspan: 2
            },{
                //title:'Shopping Cart',
                frame: false,
                border: false,
                width: 400,
                height: 400,
                colspan: 2,
                items: [ table_wrapper2 ]
            }
        ]
    });

    replaceComponentContent(targetRegion, table_wrapper);

    hideComponent(regionHelp);

</script>

Instead of :

代替 ：

    layout:'table',
    layoutConfig: {columns:2},

try this :

尝试这个 ：

    layout: {
       type: 'table',
       columns: 3,
       tableAttrs: {
          style: {
             width: '100%',
             height: '100%'
          }
       }
    },

Like I said in the reply to your other thread using vbox and hbox layouts might be a little easier for you if you want to do relative positioning. Also, if you want to stretch things to your window, put it in a Viewport, that automatically uses you entire window.

就像我在回复您的其他线程中所说的那样，如果您想进行相对定位，使用 vbox 和 hbox 布局对您来说可能会更容易一些。另外，如果你想把东西拉伸到你的窗口，把它放在一个视口中，它会自动使用你的整个窗口。

You might want to change the layout a bit (borders, frames), but with vbox and hbox layouts it would be something like this:

您可能想要稍微更改布局（边框、框架），但是对于 vbox 和 hbox 布局，它会是这样的：

new Ext.Viewport({
    layout: 'vbox',
    layoutConfig: {
        align : 'stretch',
        pack  : 'start'
    },
    defaults: {
        style: 'margin: 10px 0 0 10px'
    },
    items:[{
            title:'Orders',
            height: 200
        },{
            layout: 'hbox',
            flex: 1,
            layoutConfig: {
                align : 'stretch',
                pack  : 'start'
            },
            items: [{
                title:'Customer Information',
                flex: 1
            },{
                layout: 'vbox',
                flex: 1,
                layoutConfig: {
                    align : 'stretch',
                    pack  : 'start'
                },
                items: [{
                    title: 'Shopping cart',
                    height: 200
                },{
                    layout: 'hbox',
                    flex: 1,
                    layoutConfig: {
                        align : 'stretch',
                        pack  : 'start'
                    },
                    items: [{
                        title: 'Invoice address',
                        flex: 1
                    },{
                        title: 'Delivery address',
                        flex: 1
                    }]
                }]
            }]

        }
    ]
});

Consider using ColumnLayoutinstead. This gives you a choice between pixels and percentages for widths.

考虑ColumnLayout改用。这使您可以在像素和宽度百分比之间进行选择。
