我一直在使用此教程的IBM教程。Dojo：在添加新组后，无法更新下拉列表
http://www.ibm.com/developerworks/web/tutorials/wa-dojotoolkit/section6.html
我已经做得非常好，到目前为止，但我似乎无法得到下拉列表填充新的组条目。即使原来的代码不起作用。
//Refresh the data store for the groups dropdown (in case groups added, edited or deleted)
function refreshGroupDropDown() {
var theStore = dijit.byId("edit_contact_group").store;
theStore.close();
theStore.url = "data/groups.php";
theStore.fetch();
}
谢谢！
更新：仍然有麻烦。我在下面尝试了这一点，仍然没有。当用户打开编辑联系人窗口或新的联系人窗口时，会调用refreshGroupDropDown（）函数。
//Refresh the data store for the groups dropdown (in case groups added, edited or deleted)
function refreshGroupDropDown() {
var new_store = new ItemFileReadStore({url: 'data/groups.php' , clearOnClose: true});
var theStore = dijit.byId("edit_contact_group");
theStore.store = new_store;
theStore.close();
theStore.fetch();
}
//Clears the "Edit Contact" form, sets it up for adding a new contact
function newContact() {
var contact = contactsGrid.selection.getSelected()[0];
refreshGroupDropDown();
dojo.byId("edit_contact_real_id").value = "";
dojo.byId("edit_contact_id").value = "[NEW]";
dijit.byId("edit_contact_group").reset();
dijit.byId("edit_contact_first_name").reset();
dijit.byId("edit_contact_last_name").reset();
dijit.byId("edit_contact_email_address").reset();
dijit.byId("edit_contact_home_phone").reset();
dijit.byId("edit_contact_work_phone").reset();
dijit.byId("editContactDialog").set("title", "New Contact");
dijit.byId("editContactDialog").show();
}
//Process the adding of a new group to the database
function doNewGroup(e) {
e.preventDefault();
e.stopPropagation();
dojo.byId("new_group_ajax").value = "1";
if(this.isValid()) {
dojo.xhrPost({
form: this.domNode,
handleAs: "json",
load: function(data) {
if(data.success) {
okDialog.set("title","Group created successfully");
okDialogMsg.innerHTML = "The group <strong>"+data.name+"</strong> was created successfully.";
groupsStore.newItem({"id":data.id.toString(),"name":data.name}, {"parent": groupsModel.root, "attribute":"groups"});
groupsStore.save();
newGroupDialog.hide();
okDialog.show();
}
else {
okDialog.set("title","Error creating group");
okDialogMsg.innerHTML = data.error;
okDialog.show();
}
},
error: function(error) {
okDialog.set("title","Error creating group");
okDialogMsg.innerHTML = error;
okDialog.show();
}
});
}
}
希望这有助于！我是初学者，所以任何帮助表示赞赏。
