jquery easyUI datagrid 的寬度能不能設置成百分比。

 

數據表格組件包含兩個方法來獲取選中行的數據:

• getSelected: 獲取第一個選中行的數據，如果沒有選中的行則返回空，否則返回該行的記錄
• getSelections: 獲取所有選中行的數據，返回數組，其元素為行的記錄

創建標簽

<table id="tt"></table>

創建數據表格

$('#tt').datagrid({
    title:'Load Data',
    iconCls:'icon-save',
    width:600,
    height:250,
    url:'datagrid_data.json',
    columns:[[
        {field:'itemid',title:'Item ID',width:80},
        {field:'productid',title:'Product ID',width:80},
        {field:'listprice',title:'List Price',width:80,align:'right'},
        {field:'unitcost',title:'Unit Cost',width:80,align:'right'},
        {field:'attr1',title:'Attribute',width:100},
        {field:'status',title:'Status',width:60}
    ]]
});

用法實例

獲取選中行的數據:

var row = $('#tt').datagrid('getSelected');
if (row){
    alert('Item ID:'+row.itemid+"\nPrice:"+row.listprice);
}

獲取所有選中行的項id:

var ids = [];
var rows = $('#tt').datagrid('getSelections');
for(var i=0; i<rows.length; i++){
    ids.push(rows[i].itemid);
}
alert(ids.join('\n'));
