I want read the Chinese from Json file.
my Json file like this:
{
identifier: 'id',
label: 'name',
type:"esriFieldTypeString",
items: [
{ id: 1, name:"????",type:"esriFieldTypeString"
}
]
}
the code like this:
require(["dojo/store/JsonRest", "dojo/store/Observable", "dijit/Tree", "dijit/tree/dndSource", "dojo/query", "dojo/domReady!"],
function(JsonRest, Observable, Tree, dndSource, query) {
usGov = JsonRest({
target: "data/root.json",
mayHaveChildren: function(object) {
// see if it has a children property
return "children" in object;
},
getChildren: function(object, onComplete, onError) {
// retrieve the full copy of the object
this.get(object.id).then(function(fullObject) {
// copy to the original object so it has the children array as well.
object.children = fullObject.children;
// now that full object, we should have an array of children
onComplete(fullObject.children);
}, function(error) {
// an error occurred, log it, and indicate no children
console.error(error);
onComplete([]);
});
},
getRoot: function(onItem, onError) {
// get the root object, we will do a get() and callback the result
this.get("root").then(onItem, onError);
},
getLabel: function(object) {
// just get the name
return object.name;
},
put: function(object, options) {
this.onChildrenChange(object, object.children);
this.onChange(object);
return JsonRest.prototype.put.apply(this, arguments);
},
remove: function(id) {
// We call onDelete to signal to the tree to remove the child. The
// remove(id) gets and id, but onDelete expects an object, so we create
// a fake object that has an identity matching the id of the object we
// are removing.
this.onDelete({ id: id });
// note that you could alternately wait for this inherited add function to
// finish (using .then()) if you don't want the event to fire until it is
// confirmed by the server
// return JsonRest.prototype.remove.apply(this, arguments);
}
});
tree = new Tree({
style: 'width:300px;height:350px',
model: usGov,
dndController: dndSource
}, "tree"); // make sure you have a target HTML element with this id
tree.startup();
query("#add-new-child").on("click", function() {
var selectedObject = tree.get("selectedItems")[0];
if (!selectedObject) {
return alert("No object selected");
}
usGov.get(selectedObject.id).then(function(selectedObject) {
selectedObject.children.push({
name: "New child",
id: Math.random()
});
usGov.put(selectedObject);
});
});
query("#remove").on("click", function() {
var selectedObject = tree.get("selectedItems")[0];
if (!selectedObject) {
return alert("No object selected");
}
usGov.remove(selectedObject.id);
});
tree.on("dblclick", function(object) {
object.name = prompt("Enter a new name for the object");
usGov.put(object);
}, true);
});
}
how to do?
