w2ui grid hide and show not working properly

I am working on w2ui grid and I need to hide and show it based on certain condition. Grid is not showing back even though visibility:visible property is applied after it is hidden. It is just showing a line.
Please have a look at my code below:
HTML:
<div id="LastMileGrid" class="col-lg-6 col-sm-12 col-md-6" style="width: 100%; height: 150px"></div>
Javascript:
$('#LastMileGrid').w2grid({
name: 'LastMile',
show: {
toolbar: true,
footer: true,
toolbarReload: false,
toolbarColumns: false,
lineNumbers: true,
},
columns: [
{ field: 'recid', caption: 'ID', size: '10%', sortable: true },
//{ field: 'Header', caption: 'Header', size: '20%', editable: { type: 'text' }, sortable: true },
{ field: 'Description', caption: 'Description', size: '50%', editable: { type: 'text' }, sortable: true }
],
toolbar: {
items: [
{ id: 'add', type: 'button', caption: 'Add Record', icon: 'w2ui-icon-plus' },
{ id: 'remove', type: 'button', caption: 'Remove Record', icon: 'w2ui-icon-cross' }
],
onClick: function (event) {
if (event.target == 'add') {
var Index = w2ui['LastMile'].records.length;
w2ui['LastMile'].add({ recid: w2ui['LastMile'].records.length + 1 });
}
if (event.target == 'remove') {
var grid = w2ui["LastMile"];
grid.method = 'DELETE';
grid.delete();
}
}
},
//records: [{ recid: 'AAA' }, { recid: 'BBB' }, { recid: 'CCC' }]
});
And when opening the pop up I call the function,
$('#popup').w2popup('open', {
onOpen: function () {
if ($("#ddlMode").val() == "AIR" && ($("#drpServiceScope").val() == "D2D" || $("#drpServiceScope").val() == "A2D")) {
$('#LastMileGrid').attr("style", "visibility:visible;height:160px:")
}
else {
$('#LastMileGrid').attr("style", "visibility:collapse;")
}
},
modal: true,
});

You can try to call w2ui["LastMile"].refresh() after hiding or showing.

Answering to help others as I am late :D.
After spending a lot of time to resolve the issue,I have formulize below 2 solutions for w2ui grid show hide issue or column size issue :
1.Change the size of columns to px instead of %.
ie. use
{ field: 'lname', caption: 'Last Name', size: '30px' }
instead of
{ field: 'lname', caption: 'Last Name', size: '30%' },
2. If you wish to keep column size in % due to some requirement:
Depending on where you are rendering grid,you need to handle the resizing.
Calling refresh on grid will send data request again to server.
I don't wanted grid to make call to server each time I show/hide grid, hence written the resize of my own.
To help understand the function please note that in my application,
I have followed naming convention as follows:
If I create a grid then it will be id+"_grid",
If create a form that it will be id+"_form",
same for layout id+"_layout".
So I can get the associated component to a id and establish relation between them.
Call resize() function after you call show().
If below function doesn't help, try adding some milli seconds delay between show and my function resize().
function resize(id){
var grid=id+"_grid";
var layout=id+"_layout";
var form=id+"_form";
if(w2ui[layout]){
if($(w2ui[layout].el("main")).hasClass("w2ui-grid")){ /*means in w2ui layouts main has grid hence call resize. Calling refresh on layout "main" will make grid to reload data again ,hence grid resizing is handled in next case */
w2ui[layout].resize();
}else{
w2ui[layout].refresh();/*means main has element other than grid so refresh */
}
}
if(w2ui[form])
w2ui[form].resize();
if(w2ui[grid])
w2ui[grid].resize(); //if grid is directly rendered without a layout resize helps
}

EXTjs getEl() fails before showing the element

Good day all.
In EXTjs, probably 4.x version, I have a menu with a couple of levels of sub-menus
I'd like to add a data attribute to some of those sub-menus and actually I can do this with no problems with:
Ext.getCmp("notificationMenu").getEl().set({"data-notifynumber": 4});
but this is working only for the first element of the menu (to be clear, the element that is shown upon loading.
For any other element of the menu, first of all I have to click the menu to show all the sub-menu and only at that time I can use the getEl() function, otherwise this error is shown:
Uncaught TypeError: Cannot read property 'set' of undefined
I understand that I'd need to... show? render? well, "do something" to those sub elements in order to have them in the dom properly... I attach part of the code:
this is part of the menu I create:
xtype: 'button',
id:"notificationMenu",
hidden: false,
reference: 'userType',
style: 'color: #ffffff;width:58px;height:58px;',
glyph: 0xf0f3,
menu:{
border:0,
menuAlign: 'tr-br?',
bodyStyle: {
background: '#3e4752',
},
items:[
{
text:"TASKS",
disabled:true
},
{
text:"Campaigns",
data_id:"me_campaigns",
glyph:0xf0c1,
id:"notification_me_campaigns_root",
hidden:true,
menu:{
border:0,
menuAlign: 'tr-br?',
bodyStyle: {
background: '#3e4752',
},
items:[
{
text:"Approval",...
in this example, if I make after Render:
Ext.getCmp("notificationMenu").getEl().set({"data-notifynumber": 10})
but if I use
Ext.getCmp("notification_me_campaigns_root").getEl().set({"data-notifynumber": 4})
the error above is shown. please do you have some advice? may I call a "force render" somehow?

Try to use afterrender to get dom element.
ExtJs getEl() Retrieves the top level element representing this component but work when dom is prepared without dom creation it will return null.
I have created an Sencha Fiddle demo hope this will help you to achieve you requirement/solution.
var panel = new Ext.panel.Panel({
renderTo: document.body,
title: 'A Panel',
width: 200,
tools: [{
xtype: 'button',
text: 'Foo',
menu: {
defaults: {
handler: function () {
Ext.Msg.alert('Successs', 'You have click on <b>data-notifynumber</> ' + this.up('menu').getEl().getAttribute('data-notifynumber'))
}
},
items: [{
text: 'Item 1'
}, {
text: 'Item 2',
menu: {
listeners: {
afterrender: function () {
this.getEl().set({
"data-notifynumber": 20//only for example you can put as basis of your requirement
});
}
},
defaults: {
handler: function () {
Ext.Msg.alert('Successs', 'You have click on <b>data-notifynumber</> ' + this.up('menu').getEl().getAttribute('data-notifynumber'))
}
},
items: [{
text: 'Sub Item 1',
}, {
text: 'Sub Item 2'
}]
}
}],
listeners: {
afterrender: function () {
this.getEl().set({
"data-notifynumber": 10//only for example you can put as basis of your requirement
});
}
}
}
}]
});

Sencha Touch 2 Add and Remove textfield inside fieldset

i have strange issue with removing item from fieldset. my app success adding new textfield fieldset item, buth when i do remove() my app screen got stuck without any error on my google chrome.
here my source
view js
Ext.define('qms.view.QC23', {
extend: 'Ext.form.FormPanel',
alias: 'widget.QC23View',
id: 'QC23View',
requires: ['Ext.form.FieldSet', 'Ext.Label'],
config: {
items: [
{
xtype: 'fieldset',
//defaults: { labelAlign: 'top' },
Id:'defectAdd',
layout:{
},
items: [
{
xtype: 'button',
text: 'New Defect',
id: 'DefectQC23Button',
ui: 'action'
},
{
xtype: 'button',
text: 'Remove Defect',
id: 'RemoveQC23Button',
ui: 'action'
}
]
}
]
}
and my controler
Ext.define('qms.controller.QC23con', {
extend: 'Ext.app.Controller',
config: {
refs: {
addDefectButton:'#DefectQC23Button',
rmDefectButton:'#RemoveQC23Button'
},
control: {
addDefectButton:{
tap: 'addDefect'
},
rmDefectButton:{
tap: 'removeDefect'
},
}
},
addDefect: function(button){
button.up('fieldset').add({
xtype: 'textfield',
name: 'MyField-' + button.up('fieldset').length
});
//Ext.getCmp('defectAdd').doLayout();
},
removeDefect: function(button){
button.up('fieldset').remove(button.up('fieldset').items.items[0]);
}
the function for adding item work fine, but when i remove the item my screen stuck. i am using google chrome for testing.
please give me solution for this issue.
thanks.

I noticed you are not checking for the xtype before removing an item from the fieldset. The code might be removing the button itself in which case it might cause your screen to freeze. I created a simple sencha fiddle https://fiddle.sencha.com/#fiddle/4tf that does what you are trying to accomplish.
replace the removeDefect function with this:
var lastItem = button.up('fieldset').items.items.length-1;
if(button.up('fieldset').items.items[lastItem].xtype ==='textfield')
button.up('fieldset').remove(button.up('fieldset').items.items[lastItem]);

javascript EXTJS close & reset

The previous programmer used EXTJS, with which I don't have a whole lot of familiarity with.
The application I am trying to fix has a modal called ADD ACCOUNT, with which a user can either manually type the various input fields or drag and drop an account already open into the modal.
The user can hit a reset button and clear the fields. However, if they don't clear the fields and they just close the window, when the window is reopened, the previous data is still there.
Basically, if the user decides to close the window, it needs to also reset and clear all the fields.
As stated, I am not too familiar with EXTJS. With that said, I will include the code below, which may be a lot. I will try not to include unnecessary code.
There are 2 files: accountGrid.php and accountGrid.js
I have isolated where I think the issue begins in accountGrid.js. Here is what I've found:
function addAccount(){
var AddAccountForm;
var fields = [
{name: 'must_have', mapping: 'must_have'},
{name: "*** there are like 50 of these, so I'll skip the rest ***"}
];
AddAccount = new Ext.FormPanel({
autoScroll: true,
monitorValid: true,
defaultType: 'textfield',
items:
[
{
xtype: 'fieldset',
title: 'Required Information',
collapsible: true,
autoHeight: true,
defaultType: 'textfield',
items: [*** random fields here ***]
},
{
xtype: 'fieldset',
title: 'Optional Information',
collapsible: true,
collapsed: true,
autoHeight: true,
defaultType: 'textfield',
items: [*** random fields here ***]
}
],
buttons: *** this is where the buttons being ***
[
{
text: 'Submit',
id: 'submitAdd',
formBind: true,
handler: function(){
AddAccountForm.getForm().submit({
url: 'data-entry.php', *** hope I don't need to show this file's code ***
waitMsg: 'Updating Record...',
success: function(form, action){
obj = Ext.util.JSON.decode(action.response.responseText);
AddAccountForm.getForm().reset(); *** notice this reset function ***
delete BookingDataStore.lastParams;
BookingDataStore.removeAll();
var sa = Ext.getCmp('salesArea').getValue();
*** there are few more of these var sa fiels ***
BookingDataStore.on('beforewrite', function(store, options){
Ext.apply(options.params, {
task: 'LISTING',
salesarea: sa,
*** there are a few more of these variables ***
*** honestly, I'm not sure what these are ***
});
});
BookingDataStore.reload();
Ext.Msg.alert('Success', 'The record has been saved.');
AddAccountWindow.close();
},
failure: function(form, action){
if(action.failureType == 'server'){
obj = Ext.util.JSON.decode(action.response.responseText);
Ext.Msg.alert('Error','Your account was not submitted.'+obj['error']);
}
else{
Ext.Msg.alert('Warning','There server is unreachable: ' +action.response.responseText);
}
}
});
}
},
{
text: 'Reset', *** here is the reset ***
handler: function() {AddAccountForm.getForm().reset();}
},
{ *** 2ND EDIT ***
text: 'Close',
AddAccountForm.getForm().submit({
handler: function() {
Ext.Msg.alert('close');
};
});
} *** 2ND EDIT CONTINUED BELOW ***

That was what I think is the major portion of the accountGrid.js. There was some more code for the drag and drop feature, but that was not necessary for me to display.
I did not think this code was this long. I haven't even gotten to the php file code. SMH.
Here is the code from accountGrid.php:
var AddAccountForm = new Ext.FormPanel({
id: 'AddAccountForm',
autoScroll: true,
monitorValid: true,
submitEmptyText: false,
defaultType: 'textfield',
items:
[
{
xtype: 'fieldset',
id: 'reqFieldSet',
title: 'Required Information',
*** there are more parameters, I'll skip to the buttons ***
}
],
buttons:
[
{
text: 'Submit',
id: 'submitAdd',
formBind: true,
handler: function(){
var pc = partnerCodeField.getValue();
var pn = partnerNameField.getValue();
AddAccountForm.getForm().submit({
url: 'data-entry.php',
waitMsg: 'Updating Record....',
params: {partner_code:pc, partner_name:pn},
success: function(form, action){
obj = Ext.util.JSON.decode(action.response.responseText);
AddAccountForm.getForm()reset();
delete BookingDataStore.lastParams;
BookingDataStore.removeAll();
BookingDataStore.on('beforeload', function(store, option){
Ext.apply(options.params, {
ns_task: "SEARCHING"
});
});
BookingDataStore.load();
TradeTotalsDataStore.reload();
Ext.Msg.alert('Success','The record has been saved.');
AddAccountWindow.hide();
},
failure: function(form, action){
if(action.failureType == 'server'){
obj = Ext.util.JSON.decode(action.response.responseText);
Ext.Msg.alert('Error','Your account was not submitted.'+obj['error']);
}
else{
Ext.Msg.alert('Warning','The server is unreachable:'+action.response.responseText);
}
}
});
}
},
{

AddAccountForm.getForm().reset();
partnerCodeField.enable();
partnerNameField.enable();
}
}, *** 2ND EDIT ***
{
text: 'Close',
handler: function(){
AddAccountForm.getForm().reset();
AddAccountWindow.close();
partnerCodeField.enable();
partnerNameField.enable();
}
} *** END 2ND EDIT ***
],
keys:
[
{
key: [10, 13], fn: function(){
var b = Ext.getCmp('submitAdd');
b.focus();
b.fireEvent("click", b);
}
}
]
});
var AddAccountWindow = new Ext.Window({
title: 'Add Account',
closeable: true,
closeAction: 'hide',
y: 5,
plain: true,
layout: 'fit',
stateful: false,
items: AddAccountForm
});
I just saw this immediately after the code directly above:
function addAccount(){
AddAccountWindow.show(this);
*** beneath this is code for the drag & drop features ***
*** I don't think I need to show that ***
}
I'm not sure why the code from accountGrid.php and accountGrid.js look similar. I apologize for the amount of code. I just really need help breaking this code down.
Just to reiterate, when they click the X button at the top-right of the window, it needs to clear the modal form and then close.

You have a window with a child named accountform.
What you want to do is add a listener for the close button of the window and add code to clear your form.
You already have this:
new Ext.Window({
closable: true, //adds the close button
closeAction: 'close', //'close' isn't supported (use 'hide')
Add a listener to it:
{
//....
closable: true,
listeners: {
close:function(){
//put clear form code here
}
}
}
Add code to clear the form:
AddAccountForm.getForm().reset(true)
Finally it looks someting like this:
var AddAccountWindow = new Ext.Window({
title: 'Add Account',
closeable: true,
closeAction: 'hide',
y: 5,
plain: true,
layout: 'fit',
stateful: false,
items: AddAccountForm,
listeners: {
close:function(){
AddAccountForm.getForm().reset(true);
}
}
});

How to have the slide multiple screens in Sench touch

I am developing an application in which when submit button is clicked in the form, it should go to a different screen. However it is just printing the results outside of the window and not really going to a new screen. I have hardcoded the store to make sure there is data when I start the application and it still prints it outside of the viewable area.
Here is my Ext.data.Store:
var store = new Ext.data.Store({
model: 'jobSummary',
storeId: 'jobStore',
data : [{title: 'This is test'},
{title: 'This is test2'},
{title: 'This is test3'}]
});
Here is the list that I am using it in:
SearchJobsForm.jobsList = Ext.extend(Ext.Panel, {
dockedItems : [ {
xtype : 'toolbar',
title : 'WTJ',
dock : 'top',
items : [ {
xtype : 'button',
text : 'Back',
ui : 'back',
handler : function() {
//back button controller
},
scope : this
} ]
} ],
items : [ {
xtype : 'list',
emptyText : 'No data available.',
store : 'jobStore',
itemTpl : '<div class="list-item-title">{title}</div>'
+
'<div class="list-item-narrative">{narrative}</div>',
onItemDisclosure : function(record) {
},
grouped : false,
scroll : 'vertical',
fullscreen : true
} ],
initComponent : function() {
SearchJobsForm.jobsList.superclass.initComponent.apply(this, arguments);
}
});
And i am calling this list panel from my submit button handler which is:
var jobsList = new SearchJobsForm.jobsList();
The full code I have pasted on this link for better visibility:
http://pastebin.com/a05AcVWZ

Ok,
SearchJobsForm.form is your main panel, it will contains two components a searchForm (with text/select input) and a panel/list of results.
In the callback, we will hide() the form and show() the results list. This is not a clean code, but the simpliest and kissest one I can get from yours.
First let's instantiate the jobsList
// It has the id ( id: 'jobsListId')
var jobsList = new SearchJobsForm.jobsList();
then you should put all your inputs into a form (xtype : formpanel,
id: 'searchFormId')
And add the resultPanel just after the form
Here is the code
SearchJobsForm.form = Ext.extend(Ext.Panel,{
initComponent: function(){
Ext.apply(this, {
id: 'searchForm',
floating: true,
width: 250,
height: 370,
scroll: 'vertical',
centered: true,
modal: true,
hideOnMaskTap: false,
items: [
{
xtype: 'formpanel', // 1. this is the added formpanel
itemId: 'searchForm',
id: 'searchFormId', // this id is important
items: [
{
xtype: 'textfield',
...
}, {
xtype: 'textfield',
...
},
// all your inputs
]
},
// 2. add here the results panel : jobsList
jobsList
], // the code continues inchanged
dockedItems: [{
...
- Finally we will modify the ajax callback to hide/show the panels. Do not remove one of them, elsewhere you won't be able to reset your form
// here it comes
Ext.util.JSONP.request({
url: "http://"+serverAdd+":"+ port+"/users/searchresults.json",
format: 'json',
callbackKey: 'callback',
params : searchCriteria,
callback: function(data) {
console.log('callback');
// Call your list-filling fonctions here
// jobsList.fill(data);
Ext.getCmp('searchFormId').hide();
Ext.getCmp('jobsListId').show();
},
failure: function ( result) {
console.error('Failed');
}
});
For your next projects, I recommend you to work with classes and namespaces to avoid 1000 lined files ; Ext.ns() is your best friend and will avoid you a lot of headaches.
