向dojo datagrid添加按钮

我正在尝试向Dojo Datagrid添加删除按钮,我目前有以下 javascript

function createGrid() {
    gridTmp = new dojox.grid.DataGrid({
        store: jsonStore,
        structure: [ 
            {name: "Report No", field:"inc_number"},
            {name: "Incident Date", field: "IncidentDate"},
            {name: "Report Date", field: "reportDate"},
            {name: "Location", field: "location"},
            {name: "Delete", field: "inc_number", formatter: getDelete}
        ],
        noDataMessage: 'No results returned'
    }, "grids");

    return gridTmp;
}
dojo.addOnLoad(function() {
    grid = createGrid();
    grid.startup();
});

function getDelete(item) {
   return "<button onclick=\"location.href='/report?command=delete&reportNo="
           + store.getIdentity(item) + "'\">Delete</button>";
}

每当我加载页面时,我只会得到一个空格,上面写着“抱歉发生错误”.如果我用“getDelete”格式化程序删除最后一个字段,那么datagrid就可以正常填充.我不确定我做错了什么,所以任何帮助都将不胜感激.

你在getDelete函数中犯了几个错误:

>商店没有定义,可能你的意思是jsonStore
> item不是您商店的对象.它是属性,由“field”(inc_number)指定

我认为这对你有用:

function getDelete(item) {
  return "<button onclick=\"location.href='/report?command=delete&reportNo=" 
    + item + "'\">Delete</button>";
}
