【问题描述】:
我知道那里可能有类似的问题,但我仍然找不到答案。非常适合任何可以帮助我的人。
有5个部门,每个部门有4个产品。所以我创建了 5 个按钮和 4 个选项卡,每个选项卡都包含一个网格。默认加载部门A,用户可以切换标签查看该部门的不同产品信息。通过单击另一个按钮 B,部门 B 的信息将加载到所有 4 个选项卡。
点击每个按钮都会向后端PHP代码发送一个ajax请求,PHP会读取XML文件做计算并将数据写入“data\productA.json”、“data\productB.json”、“data\productC. json" , "data\productD.json" 文件,针对特定部门的产品 A 到产品 D。请注意,无论您单击哪个按钮,第一个选项卡始终从“data\product A”文件中读取,其他选项卡也是如此。
然后,JavaScript 将从“data\product?.json”文件中读取数据并在网格中显示数据。
页面加载时,第一个部门的信息会正确加载到网格中。但是,如果我切换到另一个部门(单击按钮),网格将不会从 json 文件中重新加载数据。
这里是JS部分:
dojo.addOnLoad(function() {
//init the first main column when load the page.
getDepartmentA();
var layout = [[
new dojox.grid.cells.RowIndex({ width: 5 }),
{name: 'Name', field: 'name'},
{name: 'Count', field: 'count'},
{name: 'Percent', field: 'percent'}
]];
var store = new dojo.data.ItemFileReadStore( { url: "data/productA.json" } );
var grid = new dojox.grid.DataGrid( { store: store, rowsPerPage: 200, style: "height:600px; width:874px;", structure: layout},
dojo.byId("grid1"));
grid.startup();
dojo.connect( dijit.byId("column3"),"onShow", dojo.partial( createGrid, "3") );
dojo.connect( dijit.byId("column4"),"onShow", dojo.partial( createGrid, "4") );
dojo.connect( dijit.byId("column5"),"onShow", dojo.partial( createGrid, "5") );
});
function getDepartmentA() {
dojo.xhrGet( {
url: "department_A_process.php",
handleAs: "json",
load: function(response) {
var tempgrid = grids[0];
var tempresponse = eval("("+response+")");
var tempstore = new dojo.data.ItemFileReadStore({url: "data/productA.json" }); //updated store!
var tempModel = new dojox.grid.data.DojoData(null, tempstore, {query:{productName:'*'}, clientSort: true});
tempgrid.setaModel(tempModel);
tempgrid.refresh();
console.dir(response); // Dump it to the console
}
});
}
function createGrid( id ) {
console.log("Calling createGrid function now!");
var layout = [[
new dojox.grid.cells.RowIndex({ width: 5 }),
{name: 'Name', field: 'name'},
{name: 'Count', field: 'count'},
{name: 'Percent', field: 'percent'}
]];
if (! grids[id] ) {
if (id =="1"){
var store = new dojo.data.ItemFileReadStore( { url: "data/productA.json" } );
console.log( "I am in tab1");
} else if (id =="3"){
var store = new dojo.data.ItemFileReadStore( { url: "data/productB.json" } );
console.log( "I am in tab3");
} else if (id =="4"){
var store = new dojo.data.ItemFileReadStore( { url: "data/productC.json" } );
console.log( "I am in tab4");
} else if (id =="5"){
var store = new dojo.data.ItemFileReadStore( { url: "data/productD.json" } );
console.log( "I am in tab5");
}
var grid = new dojox.grid.DataGrid( { store: store, rowsPerPage: 200, style: "height:600px; width:874px;", structure: layout},
dojo.byId("grid" + id ));
grid.startup();
grids[id] = grid;
console.log( grid );
}
}
我的索引页面是这样的:
<div id="mainTabContainer" dojoType="dijit.layout.TabContainer" doLayout="false">
<div id="column1" dojoType="dijit.layout.ContentPane" title="Label by Brand" selected="true">
<h1>Label by Brand</h1>
<div class="partsContainer">
<div id="grid1" class="gridContainer">
</div>
</div>
</div>
<div id="column3" dojoType="dijit.layout.ContentPane" title="Session Types">
<h1>Session Types</h1>
<div class="partsContainer">
<div id="grid3" class="gridContainer">
</div>
</div>
</div>
<div id="column4" dojoType="dijit.layout.ContentPane" title="Labels by Session">
<h1>Labels by Session</h1>
<div class="partsContainer">
<div id="grid4" class="gridContainer">
</div>
</div>
</div>
<div id="column5" dojoType="dijit.layout.ContentPane" title="Monthly Report">
<h1>Monthly Report</h1>
<div class="partsContainer">
<div id="grid5" class="gridContainer">
</div>
</div>
</div>
</div>
JSON 文件如下所示:
{
identifier: "productName",
label: "productName",
items: [
{ "productName" : "p1", "count" : 3362, "percent" : "32.8" },
{ "productName" : "p2", "count" : 421, "percent" : "4.1" },
{ "productName" : "p3", "count" : 526, "percent" : "5.1" },
{ "productName" : "p4", "count" : 1369, "percent" : "13.4" },
...
{ "productName" : "Total", "count" : 10242, "percent" : "100" }
]
}
任何人都可以帮忙,如何将PHP生成的文件重新加载到网格中?谢谢。
