    {name:'firstName',index:'firstName', width:100,searchoptions: { sopt: ['eq', 'ne', 'cn']}},
    {name:'lastName',index:'lastName', width:100,editable:true, editrules:{required:true}, editoptions:{size:10}},

    {"formatter":"myfunction", formatoptions:{baseLinkUrl:'/demo/{firstName}|view-icon'}}
]

JSON 响应

{
    "total": "10",
    "page": "1",
    "records": "3",
    "rows": [
        {
            "id": 1,
            "firstName": "John",
            "lastName": "Smith",
            "books": [{"nome": "HeadFirst"}]
        },
        {
            "id": 2,
            "firstName": "Jane",
            "lastName": "Adams",
            "books": [{"nome": "DalaiLama"}]
        },
        {
            "id": 35,
            "firstName": "Jeff",
            "lastName": "Mayer",
            "books": [{"nome": "Bobymarley"}]
        }
    ]
}

chrome 控制台检查对象

rowdata.books[0].nome
"HeadFirst"

有人知道哪里有可能的技巧吗?

Any one know where theres are possibles trick?

谢谢！

推荐答案

colModel 的 name 属性的值只能用作可用作JavaScript 中的属性名称和 CSS id 名称.所以 name:'books[0].nome' 的用法不是个好主意.

You should use as the value of name property of colModel only the names which can be used as property name in JavaScript and as CSS id names. So the usage of name:'books[0].nome' is not good idea.

要解决您的问题，您可以使用 jsonmap.例如可以使用点名转换:

To solve your problem you can use jsonmap. For example you can use dotted name conversion:

{name: 'nome', jsonmap: 'books.0.nome', ...

在更复杂的情况下，您可以使用函数作为 jsonmap 的值.例如

In more complex cases you can use functions as the value of jsonmap. For example

{name: 'nome', jsonmap: function (item) {
        return item.books[0].nome;
    }, ...
