I am trying to use one Deferred.when statement which can return an object after the completion of an eventhandler. My code looks like something below. Can someone guide me how to make it work? I am using dojo 1.7.
define(["dojo/_base/declare","dojo/_base/lang", "dojo/_base/xhr",
"dojo/_base/json","dojo/_base/Deferred","dijit/registry","dojo/_base/connect",
"dojo/query","dojo/on","dojo/dom-attr","dojo/dom","dojo/has","dojo/json","dojo/dom-style"],
function(declare,lang,xhr,json,Deferred,registry,connect,$,on,attr,dom,has,json,domStyle)
{
declare("model.Item", [],
{
deferred:null,
item:null,
Load: function(){
this.deferred = new Deferred();
var overlay = registry.byId("readFromStore");
overlay.show();
Deferred.when(connect.connect(registry.byId("storeReadOK"),"onClick",this,this.loadFromStorage), (return (this.deferred)));
// I want modification for the above line.
}
loadFromStorage:function()
{
// Do something here
this.deferred.callback(this.item);
}
return model.Item;
}
);
I also tried this below code for the Load function but it is also not working.
Load: function(){
this.deferred = new Deferred();
connect.connect(registry.byId("storeReadOK"),"onClick",this,this.loadFromStorage);
var overlay = registry.byId("readFromStore");
overlay.show();
// Deferred.when(connect.connect(registry.byId("storeReadOK"),"onClick",this,this.loadFromStorage),(overlay.hide()));
return this.deferred;
}
This below code is working fine and I was facing problem due to some other bug in my code which i have rectified and is working fine now. Thanks to all the people who tried to help me.
Load: function(){
this.deferred = new Deferred();
connect.connect(registry.byId("storeReadOK"),"onClick",this,this.loadFromStorage);
var overlay = registry.byId("readFromStore");
overlay.show();
return this.deferred;
}

I have succesfully rendered my own component as the cellEditor and would like and on-leave I would like it to try to validate the value and prevent the closing if it fails.
If I look at this then https://www.ag-grid.com/javascript-grid-cell-editing/#editing-api there's cancelable callback functions for editing. But in this callback function is there a way to access the current instantiated component? I would think that would be the easiest way to handle this.
I'm using vee-validate so the validation function is async, just to keep in mind.
Use Full row editing.
Create a global variable like
var problemRow = -1;
Then Subscribe to this events:
onRowEditingStarted: function (event) {
if (problemRow!=-1 && event.rowIndex!=problemRow) {
gridOptions.api.stopEditing();
gridOptions.api.startEditingCell({
rowIndex: problemRow,
colKey: 'the column you want to focus',
});
}
},
onRowEditingStopped: function (event) {
if (problemRow==-1) {
if (event.data.firstName != "your validation") {
problemRow = event.rowIndex
gridOptions.api.startEditingCell({
rowIndex: problemRow,
colKey: 'the column you want to focus',
});
}
}
if (problemRow == event.rowIndex) {
if (event.data.firstName != "your validation") {
problemRow = event.rowIndex
gridOptions.api.startEditingCell({
rowIndex: problemRow,
colKey: 'the column you want to focus',
});
}
else{
problemRow=-1;
}
}
},
I had a similar issue - albeit in AngularJS and the non-Angular mode for ag-grid - I needed to prevent the navigation when the cell editor didn't pass validation.
The documentation is not very detailed, so in the end I added a custom cell editor with a form wrapped around the input field (to handle the niceties such as red highlighting etc), and then used Angular JS validation. That got me so far, but the crucial part was trying to prevent the user tabbing out or away when the value was invalid so the user could at least fix the issue.
I did this by adding a value parser when adding the cell, and then within that if the value was invalid according to various rules, throw an exception. Not ideal, I know - but it does prevent ag-grid from trying to move away from the cell.
I tried loads of approaches to solving this - using the tabToNextCell events, suppressKeyboardEvent, navigateToNextCell, onCellEditingStopped - to name a few - this was the only thing that got it working correctly.
Here's my value parser, for what it's worth:
var codeParser = function (args) {
var cellEditor = _controller.currentCellEditor.children['codeValue'];
var paycodeId = +args.colDef.field;
var paycodeInfo = _controller.paycodes.filter(function (f) { return f.id === paycodeId; })[0];
// Check against any mask
if (paycodeInfo && paycodeInfo.mask) {
var reg = new RegExp("^" + paycodeInfo.mask + '$');
var match = args.newValue.match(reg);
if (!match) {
$mdToast.show($mdToast.simple().textContent('Invalid value - does not match paycode format.').position('top right').toastClass('errorToast'))
.then(function(r) {
_controller.currentCellEditor.children['codeValue'].focus();
});
throw 'Invalid value - does not match paycode format.';
}
}
return true;
};
The _controller.currentCellEditor value is set during the init of the cell editor component. I do this so I can then refocus the control after the error has been shown in the toast:
CodeValueEditor.prototype.init = function (params) {
var form = document.createElement('form');
form.setAttribute('id', 'mainForm');
form.setAttribute('name', 'mainForm');
var input = document.createElement('input');
input.classList.add('ag-cell-edit-input');
input.classList.add('paycode-editor');
input.setAttribute('name', 'codeValue');
input.setAttribute('id', 'codeValue');
input.tabIndex = "0";
input.value = params.value;
if (params.mask) {
input.setAttribute('data-mask', params.mask);
input.setAttribute('ng-pattern','/^' + params.mask + '$/');
input.setAttribute('ng-class',"{'pattern-error': mainForm.codeValue.$error.pattern}");
input.setAttribute('ng-model', 'ctl.currentValue');
}
form.appendChild(input);
this.container = form;
$compile(this.container)($scope);
_controller.currentValue = null;
// This is crucial - we can then reference the container in
// the parser later on to refocus the control
_controller.currentCellEditor = this.container;
$scope.$digest();
};
And then cleared in the grid options onCellEditingStopped event:
onCellEditingStopped: function (event) {
$scope.$apply(function() {
_controller.currentCellEditor = null;
});
},
I realise it's not specifically for your components (Vue.js) but hopefully it'll help someone else. If anyone has done it a better way, I'm all ears as I don't like throwing the unnecessary exception!
i am trying to make the same app with the miamicode, i am at step 3
http://miamicoder.com/2012/how-to-create-a-sencha-touch-2-app-part-3/
i try to make the button that goes to new note (switch to a new screen and create a new note)
the code at the example is this:
onNewNoteCommand: function () {
console.log("onNewNoteCommand");
var now = new Date();
var noteId = (now.getTime()).toString() + (this.getRandomInt(0, 100)).toString();
var newNote = Ext.create("NotesApp.model.Note", {
id: noteId,
dateCreated: now,
title: "",
narrative: ""
});
this.activateNoteEditor(newNote);
}
the activateNotesList function is this :
activateNotesList: function () {
Ext.Viewport.animateActiveItem(this.getNotesListView(), this.slideRightTransition);
on my own example i try just to go the editview without passing data.
so i try this:
onNewNoteCommand:function()
{
var noteEditor = this.getNoteEditor();
// Ext.Viewport.add(noteEditor); also tried this.
Ext.Viewport.setActiveItem(noteEditor);
that code runs with no errors but the screen doesn't change.
any suggestion? whats the difference on add ?
how do i set the viewport (haven't created any custom viewport) to card? is this the problem that setactiveitem doesn't work? any other way to switch between views?
Are there some errors in google chrome browser's console? Ctrl+Shift+J to open.
Also you have to check if noteEditor equals Object or Number.
From sencha docs: setActiveItem( Object/Number activeItem )
I've been playing around with IBM's tutorial at this link.
http://www.ibm.com/developerworks/web/tutorials/wa-dojotoolkit/section6.html
I've done very well so far, but I can't seem to get the drop down list to populate the new group entry. Even the original code isn't working.
//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();
}
Thanks!
Update: Still having trouble. I tried this below and still nothing. The function refreshGroupDropDown() is called when the user opens the edit contact windows or new contact window.
//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();
}
});
}
}
Hopefully this helps! I'm a beginner so any help is appreciated.
I figured it out! The issue was with the index.html. The input tag for the groups drop-down list looks like this
<input dojoType="dijit.form.FilteringSelect" name="move_contact_new" store="groupsStore" searchAttr="name" query="{type:'node'}" id="move_contact_new" required="true" style="margin-bottom: 6px" />
The query attribute was never set correctly. Once I deleted query="{type:'node'}" the groups re-populate after adding, editing, or deleting groups.
A beginner answer for a beginner question.
Hope this can help any beginners out there.
Based on what you've posted, the only problem I see is with the line var theStore = dijit.byId("edit_contact_group").store;because it doesn't acutally create a dataStore. You need to make sure you also include something like `var edit_contact_group = new dojo.data.ItemFileReadStore();or an equivalent. Othewise, have you connected the refreshGroupDropDown() function to the appropriated event ('onclick' or whatever) using dojo.connect()? Have you loaded the function refreshGroupDropDown() using dojo.ready? ie. dojo.ready(function(){refreshGroupDropDown();});Those are always the first things that come to mind...
dojo newbie - giving it a shot.
After submitting a form, If an error is returned from the server I would like to show that message on the dijit.form.ValidationTextBox
var user_email = dijit.byId("login_user_email");
user_email.set("invalidMessage", data["result"]["user_email"]);
//need to force show the tooltip but how???
Any help much appreciated.
See it in action at jsFiddle.
Just show tooltip:
var textBox = bijit.byId("validationTextBox");
dijit.showTooltip(
textBox.get("invalidMessage"),
textBox.domNode,
textBox.get("tooltipPosition"),
!textBox.isLeftToRight()
);
Temporarily switch textBox validator, force validation, restore the original validator:
var originalValidator = textBox.validator;
textBox.validator = function() {return false;}
textBox.validate();
textBox.validator = originalValidator;
Or do both at once.
I think you can show the tooltip via myVTB.displayMessage('this is coming from back end validation'); method
you need to do the validation in the validator-method. like here http://docs.dojocampus.org/dijit/form/ValidationTextBox-tricks
you also need to focus the widget to show up the message! dijit.byId("whatever").focus()
#arber solution is the best when using the new dojo. Just remember to set the focus to the TextBox before calling the "displayMessage" method.
I am using dojo 1.10 which works create as follows:
function showCustomMessage(textBox, message){
textBox.focus();
textBox.set("state", "Error");
textBox.displayMessage(message);
}
Dojo reference guid for ValidationTextBox: https://dojotoolkit.org/reference-guide/1.10/dijit/form/ValidationTextBox.html
I know this question is ancient, but hopefully this'll help someone. Yes, you should use validators, but if you have a reason not to, this will display the message and invalidate the field:
function(textbox, state /*"Error", "Incomplete", ""*/, message) {
textbox.focus();
textbox.set("state", state);
textbox.set("message", message);
}
You can call directly the "private" function:
textBox._set('state', 'Error');
You get the same result as #phusick suggested but with less code and arguably in a more direct and clean way.
Notes:
_set is available to ValidationTextBox as declared on its base class dijit/_WidgetBase.
Live demo:
http://jsfiddle.net/gibbok/kas7aopq/
dojo.require("dijit.form.Button");
dojo.require("dijit.form.ValidationTextBox");
dojo.require("dijit.Tooltip");
dojo.ready(function() {
var textBox = dijit.byId("validationTextBox");
dojo.connect(dijit.byId("tooltipBtn"), "onClick", function() {
dijit.showTooltip(
textBox.get('invalidMessage'),
textBox.domNode,
textBox.get('tooltipPosition'), !textBox.isLeftToRight()
);
});
dojo.connect(dijit.byId("validatorBtn"), "onClick", function() {
// call the internal function which set the widget as in error state
textBox._set('state', 'Error');
/*
code not necessary
var originalValidator = textBox.validator;
textBox.validator = function() {return false;}
textBox.validate();
textBox.validator = originalValidator;
*/
});
});
I have a dijit.editor on my page and when I click on a button I want the contents inside my editor. It should be fairly simple, but I've stumbled upon it for now.
Never mind, i solved it.
dojo.require("dijit.Editor");
dojo.addOnLoad(function() {
var editor = dijit.byId("myEditor");
var btn1 = dojo.byId("Button1");
editor.attr("value", "Hej igen");
editor.onLoadDeferred.addCallback(function() {
editor.atte("value", "<b>This is new content.</b>");
});
btn1.onclick = function() {
// alert(editor.domNode.innerHTML);
alert(editor.attr("value"));
}
});
As marko has pointed out, you can get the value by:
editor.attr("value")
