一开始给的解决方案如下

$(‘#xx’).datagrid.(‘hideColumn’,’field’) 

这也是easyui API中给出的解决方案，但是在这里并不管用，后来向组里的大神请教了以后，又换了另外一种方法

全部代码如下

{ field: ‘ck’, checkbox: true }, 
{ 
field: ‘LoginName’, title: ‘登录名’, align: ‘center’, width: 150 
}, 
{ 
field: ‘UserName’, title: ‘显示名’, align: ‘center’, width: 100 
}, 
{ 
field: ‘TelPhoneNum’, title: ‘手机号’, align: ‘center’, width: 150 
}, 
{ 
field: ‘Telephone’, title: ‘办公电话’, align: ‘center’, width: 100 
}, 
{ 
field: ‘RightOrgName’, title: ‘单位’, align: ‘center’, width: 150 
}, 
{ 
field: ‘IP’, title: ‘IP地址’, align: ‘center’, width: 150 
}, 
{ 
field: ‘EmailAddress’, title: ‘电子邮箱’, align: ‘center’, width: 200 
}, 
{ 
field: ‘Sort’, title: ‘排序’, align: ‘center’, width: 200 
}

]],
pagination: true,
rownumbers: true,
singleSelect: true,
queryParams: {
    condition: Condition,
},
onLoadSuccess: function () {
    if (getcheckDBS == "1" && oAppId != 9) {
        $('td[field="Telephone"]').hide();
        $('td[field="IP"]').hide();
        $('td[field="EmailAddress"]').hide();
    }
    if (getcheckDBS == "1") {
        $('td[field="Telephone"]').hide();
        $('td[field="IP"]').hide();
        $('td[field="EmailAddress"]').hide();
    }
}
