jquery easyUI datagrid 的宽度能不能设置成百分比。

 

数据表格组件包含两个方法来获取选中行的数据:

• getSelected: 获取第一个选中行的数据，如果没有选中的行则返回空，否则返回该行的记录
• getSelections: 获取所有选中行的数据，返回数组，其元素为行的记录

创建标签

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

创建数据表格

$('#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}
    ]]
});

用法实例

获取选中行的数据:

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

获取所有选中行的项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'));

//获取行数getSelections

//获取行数内容 getSelected

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

 alert(ids);

 

 

//只能在页面中删除行 不能对数据库操作...

function del(){
 var rows = $('#tt').datagrid("getSelections"); //获取你选择的所有行 
 //循环所选的行
 for(var i =0;i<rows.length;i++){
  var index = $('#tt').datagrid('getRowIndex',rows[i]);//获取某行的行号
  $('#tt').datagrid('deleteRow',index); //通过行号移除该行
 }
}

 

 

//获取页面中选择行的id和数量

function getSelectedArr() {
    var ids = [];
 var rows = $('#tt').datagrid('getSelections');
 for(var i=0; i<rows.length; i++){
     ids.push(rows[i].g_id);
 }
    return ids;
}

 

 

var arr = getSelectedArr();
 var num = arr.length;
