Ext.Defer gives getAsynchronousLoad Error

I've just defined a combobox. Firstly it loads a countrylist and when select a value it's fire a change event which doing a ajax query to DB within searching service;
The thing; this configuration works pretty well when I click and open combobox items. But when I'm typing to combobox's field it's fires listener's store.load and because of none of country selected yet, the search query url gives not found errors of course.
{
xtype: 'countrycombo',
itemId: 'countryName',
name:'country',
afterLabelTextTpl: MyApp.Globals.required,
allowBlank: false,
flex: 1,
// forceSelection: false,
// typeAhead: true,
// typeAheadDelay: 50,
store: {
proxy: {
type: 'ajax',
// isSynchronous: true,
url: MyApp.Globals.getUrl() + '/country/list?limit=250',
// timeout: 300000,
reader: {
type: 'json',
rootProperty: 'data'
}
},
pageSize: 0,
sorters: 'description',
autoLoad: true
}
,
listeners: {
change: function (combo, countryId) {
var cityStore = Ext.getStore('cityCombo');
cityStore.getProxy()
.setUrl(MyAppp.Globals.getUrl() + '/city/view/search?query=countryid:'+ countryId);
// Ext.defer(cityStore.load, 100);
cityStore.load();
}
}
},
I've tried several things as you see in code above to set a delay/timeout for load during typing to combobox text field; Ext.defer, timeoutconfig on proxy, typeAhead config on combo but none of them worked!
I thought that Ext.defer is the best solution but it gives this error:
Uncaught TypeError: me.getAsynchronousLoad is not a function at load (ProxyStore.js?_dc=15169)
How can I set a delay/timeout to combobox to fires load function?

Instead of Ext.defer(cityStore.load, 100);
try using this :
Ext.defer(function(){
cityStore.load
}, 300);
If this doest work, try increasing your delay
or you can put a logic before loading
like this :
if(countryId.length == 5){
cityStore.load
}
This will ensure that you Entered the right values before loading
Hope this helps, and Goodluck on your project

well.. I've tried to implement #Leroy's advice but somehow Ext.defer did not fire cityStore.load. So I keep examine similar situations on google and found Ext.util.DelayedTask
So configured the listerens's change to this and it's works pretty well;
listeners: {
change: function (combo, countryId) {
var alert = new Ext.util.DelayedTask(function () {
Ext.Msg.alert('Info!', 'Please select a country');
});
var cityStore = Ext.getStore('cityCombo');
cityStore.getProxy().setUrl(MyApp.Globals.getUrl() + '/city/view/search?query=countryid:'+ countryId);
if (typeof countryId === 'number') {
cityStore.load();
} else {
alert.delay(8000);
}
}
}

Open only one popup window (panel)

So i have this function onDisplayError which is called each time if request fails. This means if user press save button and 3 request are failing i currently getting 3 popup messages. My goal is that this function checks if my popup window is already opened. If it is then i will append errors in my already opened window otherwise it should open this error popup
onDisplayError: function (response, message) {
var errorPanel = Ext.create('myApp.view.popup.error.Panel',{
shortMessage: message,
trace: response
});
if(errorPanel.rendered == true){
console.log('Do some other stuff');
}else{
errorPanel.show();
}
},
This is Panel.js
Ext.define('myApp.view.popup.error.Panel', {
extend: 'Ext.panel.Panel',
requires: [
'myApp.view.popup.error.PanelController'
],
controller: 'myApp_view_popup_error_PanelController',
title: 'Fail',
glyph: 'xf071#FontAwesome',
floating: true,
draggable: true,
modal: true,
closable: true,
buttonAlign: 'center',
layout: 'border',
shortMessage: false,
width: 800,
height: 200,
initComponent: function() {
this.items = [
this.getMessagePanel(),
this.getDetailsPanel()
];
this.callParent(arguments);
},
getMessagePanel: function() {
if(!this.messagePanel) {
var message = this.shortMessage;
this.messagePanel = Ext.create('Ext.panel.Panel', {
bodyPadding: 5,
height: 200,
region: 'center',
border: false,
html: message
});
}
return this.messagePanel;
},
getDetailsPanel: function() {
if(!this.detailsPanel) {
this.detailsPanel = Ext.create('Ext.panel.Panel', {
title: 'Details',
hidden: true,
region: 'south',
scrollable: true,
bodyPadding: 5,
height: 400,
html: '<pre>' + JSON.stringify(this.trace, null, 4) + '</pre>'
});
}
return this.detailsPanel;
}
The problem is that i'm still getting multiple popups displayed. I think that the problem is that var errorPanel loses reference so it can't check if this popup (panel) is already opened. How to achieve desired effect? I'm working with extjs 6. If you need any additional information's please let me know and i will provide.

You could provide to your component definition a special xtype.
Ext.define('myApp.view.popup.error.Panel', {
extend: 'Ext.panel.Panel',
xtype:'myxtype'
and then you could have a very condensed onDisplayError function:
onDisplayError: function (response, message) {
var errorPanel = Ext.ComponentQuery.query('myxtype')[0] || Ext.widget('myxtype');
errorPanel.appendError(message, response)
errorPanel.show();
},
The panel's initComponent function should initialize an empty window, and appendError should contain your logic to append an error (which may be the first error as well as the second or the third) to the list of errors in the panel.

Using Ext.create will always create a new instance of that class.
You can use the reference config to create a unique reference to the panel.
Then, use this.lookupReference('referenceName') in the controller to check if the panel already exists, and show().
You also have to set closeAction: 'hide' in the panel, to avoid panel destruction on close.
Otherwise, you can save a reference to the panel in the controller
this.errorPanel = Ext.create('myApp.view.popup.error.Panel' ....
Then, if (this.errorPanel) this.errorPanel.show();
else this.errorPanel = Ext.create...

jQuery does not work when reload the page content via ajax

I use Bootstrap to display a popover, until there is with all this code below everything works normal.
$(".emoticons").popover({
html : true,
placement : 'bottom',
animation : true,
delay: { show: 100, hide: 500 },
content: function() {return $('.emoticonimg').html();
}
});
I only need to load the content of the page via ajax, then I changed the code because when I load the content dynamically I need to delegate events, changed the code and it looked like this:
$('body').on('click','.emoticons',function()
{
$(".emoticons").popover({
html : true,
placement : 'bottom',
animation : true,
delay: { show: 100, hide: 500 },
content: function() {return $('.emoticonimg').html();
}
});
});
Now my troubles started. The code works however when I click the first time it does not work, so it works when I click more than once on the link. What to do?

What's happening is that when you are clicking on the .emoticons and executing your popover function, it is at that moment that you are binding it to your click. That's why it doesn't work the first time, but it works afterwards. It starts listening to the click event after that.
Ideally, the solution is to run the .popover function when the new content is loaded (on your AJAX callback).
If you want to just copy paste my code and see if it works, you can do this:
$('body').on('click','.emoticons',function()
{
// Convert this element into a popover and then display it
$(this).popover({
html : true,
placement : 'bottom',
animation : true,
delay: { show: 100, hide: 500 },
content: function() {
return $('.emoticonimg').html();
}
}).popover('toggle');
});
But, I would NOT recommend this code specifically, since you are re-initializing your popover every time you click on it.
It's better and more clear if you bind all popovers after your AJAX request is done:
$.ajax( "BlaBlaBla.php" )
.done(function() {
// Convert all emoticons to popovers
$(".emoticons").popover({
html : true,
placement : 'bottom',
animation : true,
delay: { show: 100, hide: 500 },
content: function() {
return $('.emoticonimg').html();
}
});
});

It doesn't work the first time because the first click if firing off the body onclick handler which binds your popover.
Try something like this in your $(document).ready() function.
$(".emoticons").click(function(){
$(this).popover({
html : true,
placement : 'bottom',
animation : true,
delay: { show: 100, hide: 500 },
content: function() {return $('.emoticonimg').html();
}
});
});

JS Object being logged as HTML Element

I am working on a javascript control for work, and integrating it into a grails plugin. All the plugin simply does is populate the options based on a taglib, which looks like this:
$(document).ready(function() {
var ${name} = $("#${name}").tagInput({
$inputListener: $("#${inputListenerName}"),
$errorHandler: $("#${errorHandler}"),
$domainListener: $("#${domainListenerName}"),
errorClass: "${errorClass}",
validClass: "${validClass}",
caseSensitive: ${caseSensitive},
constraints: {
minSize: ${minSize},
maxSize: ${maxSize},
maxTags: ${maxTags},
validationRegex: "${tagRegex}"
},
errorMessages: {
size: "${sizeErrorMessage}",
regex: "${regexErrorMessage}",
maxTags: "${maxTagsError}"
},
responsive: {
length: ${maxTagLength},
lengthxs: ${maxTagLengthxs},
xsMode: ${xsWidth}
}
});
debugger;
});
Which looks like this when evaluated:
var emailTags = $("#emailTags").tagInput({
$inputListener: $("#invitesInput"),
$errorHandler: $("#inviteErrors"),
$domainListener: $("#null"),
errorClass: "label-danger",
validClass: "label-primary",
caseSensitive: false,
constraints: {
minSize: 1,
maxSize: 255,
maxTags: 100,
validationRegex: "[^#]+#[^#]+\.[^#]+"
},
errorMessages: {
size: "",
regex: "Must be a valid email string.",
maxTags: "You have entered too many recipients. Please send out invites before adding more recipients."
},
responsive: {
length: 50,
lengthxs: 20,
xsMode: 768
}
});
When Chrome hits the debugger statement, I have the correct object. Which is:
tagInput {parseTags: function, clear: function, serialize: function}
If I step out of this, I immediately entry jQuery and my object is instantly turned into
div#emailTags.turningTags
which eventually turns into
<div id=​"emailTags" name=​"emailTags" class=​"turningTags ">​…​</div>​
If it helps, here is the current code for the tagInput object.
https://gist.github.com/anonymous/e785ec24e0c1388cd599
Why is this happening? Why is my object being turned into this HTML element? I have tried changing the name of the variable to no avail, no matter what I change the name of this variable to, it happens every time. I have tried making it a standalone object and not a jQuery function and the same thing STILL keeps happening.

how to load mask while the grid is double clicked to wait for the detail window

forum member I am having one problem while using the loadMask property of the extjs 4.0.2a. Actually I am having one grid which on click open the window with detail information.
As my detail window takes more time to come on screen, so I just decided to make use of the loadMask property of Extjs. But don't know why the loading message is not shown when I double click the grid row and after some time the detail window is shown on the screen.
on grid double click I am executing the below code
projectEditTask: function(grid,cell,row,col,e) {
var myMask = new Ext.LoadMask(Ext.getBody(), {msg:"Loading.."});
myMask.show();
var win = this.getProjectGanttwindow();
win.on('show', myMask.hide, myMask);
}
but don't know the loading is not displayed and after waiting for some moment my window is shown correctly.
I just want when I double click the grid Loading message should be displayed and after when the window is load completely Loading message should be dissapear and detail window should be viewed.
when I made the changes as per you said the loading message is displayed but my window is not opened yet. below is the code of window I am trying to open
my projectGanttwindow is
Ext.define('gantt.view.projectmgt.projectGanttwindow' ,{
extend: 'Ext.window.Window',
alias : 'widget.projectganttwindow',
requires: ['gantt.view.projectmgt.projectGanttpanel'],
editform:1,
id: 'projectganttwindow',
title: 'Project Management',
width: '100%',
height: '100%',
closeAction: 'destroy',
isWindow: true,
flex:1,
isModal: true,
constrain: true,
maximizable: true,
stateful: false,
projectId: null, // this will be set before showing window
listeners: {
hide: function() {
alert('hide');
//var store = Ext.data.StoreManager.lookup('taskStore').destroyStore();
//Ext.destroy(store);
//store.destroyStore();
console.log('Done destroying');
}
},
initComponent: function() {
var me = this;
me.layoutConfig = {
align: 'stretch'
};
me.items = [{
xtype: 'projectganttpanel',
allowBlank: false
}];
me.callParent(arguments);
me.on({
scope: me,
beforeshow: me.onBeforeShow
});
},
onBeforeShow: function() {
var projectId = this.projectId;
console.log('BEFOR SHOW ::'+projectId);
if(projectId != null) {
var store = Ext.data.StoreManager.lookup('taskStore');
store.load({
params: {'id': projectId}
});
}
}
});

Try this
function loadMask(el,flag,msg){
var Mask = new Ext.LoadMask(Ext.get(el), {msg:msg});
if(flag)
Mask.show();
else
Mask.hide();
}
When u click on grid call this function
//Enable mask message
loadMask(Ext.getBody(),'1','Please wait...');
After pop loaded call
//Disable mask Message
loadMask(Ext.getBody(),'','Please wait...');
