我在一家公司接受培训，我需要使用2012年编程的另一名受训人员的程序。所以我做了一些更新，但我遇到了一些问题：
当我按下按钮时，我有一个JS使xhr.get恢复JSON。但是我的firefox控制台上有这条消息：
Object { message: "Unable to load /query/?typeForm=com…", stack:".cache["dojo/errors/create"]/</</g@…", response: Object, status: 0,responseText: "", xhr: XMLHttpRequest }
我的JS：
function queryDataGrid(map, stringForm) {
var test = "pouet";
require(["dojox/grid/DataGrid",
"dojo/store/Memory",
"dojo/data/ObjectStore",
"dojo/_base/xhr",
"dojo/domReady!",
"dojo/dom",
"dojo/_base/array"],
function(DataGrid, Memory, ObjectStore, xhr, arrayUtil, dom) {
var nodeDomGrid = dom.byId("datagrid");
window.alert("hey");
xhr.get({
url: "/query/",
form: dom.byId(stringForm),
handleAs: "json",
load: function(data) {
var nodeDomGrid = dom.byId("datagrid");
var nodeGrid = dijit.byId("datagrid");
var gridLayout = [];
var dataStore = new ObjectStore({ objectStore:new Memory({ data: data.fields }) });
console.log("store");
console.log(data.fields[0][1]);
globalData = data;
for(i in data.columns) {
gridLayout.push({
name: data.columns[i],
field: data.columns[i],
width: "auto"
})
}
nodeGrid.setStructure(gridLayout);
nodeGrid.setStore(dataStore);
var nodeMap = dom.byId("map");
columns = data.columns;
columnsToDisplay = []
numberColumn = 0;
for (i in columns) {
if (columns[i] == "Distance Fin") {
numberColumn = i
}
if (parseInt(i) > parseInt(numberColumn) && numberColumn != 0) {
columnsToDisplay.push({ value: columns[i], label: columns[i]});
}
}
dijit.byId("dataToColor").addOption(columnsToDisplay);
var vectorLayer = map.getLayersByName("KML")[0];
vectorLayer.removeAllFeatures();
var kmlFile = createKMLFile(data.kmldata, dom.byId("hiddenColor").value, dom.byId("sizeLine").value, dom.byId("colourPR").style.backgroundColor, dom.byId("sizePR").value);
var features = KMLToFeatures(kmlFile);
var bounds;
for(var i=0; i<features.length; ++i) {
if (!bounds) {
bounds = features[i].geometry.getBounds();
} else {
bounds.extend(features[i].geometry.getBounds());
}
}
vectorLayer.addFeatures(features);
console.log(vectorLayer);
map.zoomToExtent(bounds);
refreshLayer(vectorLayer);
if (stringForm == "commonQueriesForm" && dijit.byId("table").get("value") == "location") {
dom.byId("colourPalette").style.display = "block";
dom.byId("styleKML").style.display = "none";
}
else {
dom.byId("colourPalette").style.display = "none";
dom.byId("styleKML").style.display = "block";
}
},
// Message d'erreur à modifier
error: function() {
nodeDomGrid.innerHTML = "La requête a engendré une erreur.";
}
})
});
console.log(stringForm);
};
我的表格：
<form id="commonQueriesForm" data-dojo-type="dijit.form.Form" onload="alert('test')">

<div id="commonDataTitlePane" data-dojo-type="dijit.TitlePane" data-dojo-props="title: 'Requêtes'">

答案 0 :(得分：-1)
JS代码正在尝试加载绝对路径/query/，但您的Django模式已设置为响应^home/query。尝试使用/home/query作为xhr网址。
