Javascript Dojo数据网格未显示

在我的

dojo.xhrGet

中，我指定了这个

加载：

：

load: function (data) {
    // reset data display containers
    dojo.addClass("search_results", "hide_on_load");
    dojo.byId("search_results_found").innerHTML = "";
    // populate table with new results.
    dojo.byId("search_results_found").innerHTML = "" + data.length + " search result(s) found.";

    // when data is from an XHR request, you must transform it into a store.
    // See: http://stackoverflow.com/questions/2423459/datagrid-in-dojo-with-json-data-from-a-servlet
    var items = dojo.map(data, function (res_row) {
        return {
            'Id': res_row.Id,
            'Name': res_row.Name,
            'VisitType': res_row.VisitType,
            'VisitDate': res_row.VisitDate
        };
    });

    var store = new dojo.data.ItemFileReadStore({
        data: {
            items: items
        }
    });

    var res_layout = [
        {field: 'Id',        name: 'ID',         width: '10%'},
        {field: 'Name',      name: 'Site Name',  width: '50%'},
        {field: 'VisitType', name: 'Visit Type', width: '20%'},
        {field: 'VisitDate', name: 'Visit Date', width: '20%'}
        ];

    // create a new grid:
    var res_grid = new dojox.grid.DataGrid({
        store: store,
        structure: res_layout,
        rowsPerPage: 10
    }, document.createElement('div'));

    // append the new grid to the div "search_results_table":
    dojo.byId("search_results_table").appendChild(res_grid.domNode);

    // Call startup, in order to render the grid:
    res_grid.startup();

    dojo.removeClass("search_results", "hide_on_load");
    standby.hide();
},

而且，html是：

<!-- Search Results Table -->
<div id="search_results" class="hide_on_load">
    <div id="search_results_found"></div>
    <div id="search_results_table"></div>
</div>

确保通过放置网格的div上的style属性设置大小，不要忘记为网格导入CSS文件，如：

<style type="text/css">
    @import "dojoroot/dojox/grid/resources/Grid.css";
    @import "dojoroot/dojox/grid/resources/soriaGrid.css";

    .dojoxGrid table {
        margin: 0;
    }
</style>

@导入“dojoroot/dojox/grid/resources/grid.css”；
@导入“dojoroot/dojox/grid/resources/soriaGrid.css”；
.dojoxGrid表{
保证金：0；
}

注意：用你正在使用的主题替换soria

。。。不要忘记为网格的dom节点设置大小：

<div id="gridnode" style="width:100%; height:500px;"></div>

如果不需要固定高度，可以使用

autoHeight:true

声明网格

var res_grid = new dojox.grid.DataGrid({

        store: store,
        structure: res_layout,
        rowsPerPage: 10,
        autoHeight: true
    }, document.createElement('div'));

使用此属性，您无需向父容器添加样式即可显示它。

能否尝试在div上添加宽度和高度，如“”？是的，就是这样！！！！谢谢你，菲利普！请更新您的答案，然后我会接受它。：）

var res_grid = new dojox.grid.DataGrid({

        store: store,
        structure: res_layout,
        rowsPerPage: 10,
        autoHeight: true
    }, document.createElement('div'));
