问题描述

我是新来的extjs。我想显示每个网格元素的图标图像。
你可以帮助我吗?



我从xml文件中获取图像路径。



我的代码在下面。这里我正在显示图像路径。



我必须通过显示图像来替换它。

 code> Ext.onReady(function(){

var store = new Ext.data.Store({
url:'new_frm.xml',

reader:new Ext.data.XmlReader({
record:'message',
fields:[{name:'first'},{name:'last'},{name:'company '},{name:'email'},{name:'gender'},{name:'form-file'},{name:'state'},{name:'Live'},{name:'content '}]
})
});

var grid = new Ext.grid.GridPanel({
store:store,
columns:
{header:First Name,width:120,dataIndex:'first',sortable:true},
{header:Last Name,width:180,dataIndex:'last',sortable :true},
{header:Company,width:115,dataIndex:'company',sortable:true},
{header:E邮件,width:100,dataIndex:'email',sortable:true},
{header:Gender,width:100,dataIndex:'gender',sortable:true},
{header :Photo,width:100,dataIndex:'form-file',sortable:true},
{header:State,width:100,dataIndex:'state',sortable:true},
{header:Living with,width:100,dataIndex:'Live',sortable:true},
{header:Commands,width:100,dataIndex:'content',sortable:true}

],
renderTo:'example-grid',
height:200
});

store.load();
});


解决方案

您需要在列中添加一个渲染器,想要显示图像。渲染器值是调用渲染图像标签的函数。



修改了一个列元素:

  {header:Photo,width:100,renderer:renderIcon,dataIndex:'form-file',sortable:true},
/ pre>

示例渲染器函数:

  function renderIcon ){
return'< img src ='+ val +'>';
}

在这个例子中,dataIndex的值必须是图片。如果没有,那么你必须添加一些额外的逻辑。


I am new to extjs. I want to display icon images for each grid elements.can you please help me anybody?

I am getting the image path from an xml file.

My code is below. here I am displaying image path.

I have to replace it by displaying image.

Ext.onReady(function(){

      var store = new Ext.data.Store({
        url: 'new_frm.xml',

               reader: new Ext.data.XmlReader({
               record: 'message',
               fields: [{name: 'first'},{name: 'last'},{name: 'company'},{name: 'email'},{name: 'gender'},{name: 'form-file'},{name: 'state'},{name: 'Live'},{name: 'content'}]
           })
    });

      var grid = new Ext.grid.GridPanel({
        store: store,
        columns: [
            {header: "First Name", width: 120, dataIndex: 'first', sortable: true},
            {header: "Last Name", width: 180, dataIndex: 'last', sortable: true},
            {header: "Company", width: 115, dataIndex: 'company', sortable: true},
            {header: "Email", width: 100, dataIndex: 'email', sortable: true},
            {header: "Gender", width: 100, dataIndex: 'gender', sortable: true},
            {header: "Photo", width: 100, dataIndex: 'form-file', sortable: true},
            {header: "State", width: 100, dataIndex: 'state', sortable: true},
            {header: "Living with", width: 100, dataIndex: 'Live', sortable: true},
            {header: "Commands", width: 100, dataIndex: 'content', sortable: true}

        ],
        renderTo:'example-grid',
        height:200
    });

    store.load();
});
解决方案

You need to add a renderer to your columns that you want to display an image. The renderer value is the function to call to render the image tag.

One of your column elements modified:

{header: "Photo", width: 100, renderer:renderIcon, dataIndex: 'form-file', sortable: true},

A sample renderer function:

function renderIcon(val) {
    return '<img src="' + val + '">';
}

In this example, the value of the dataIndex must be the full path of the image. If not then you must add some additional logic.
