My aim is simple, for some needs, I have to test the "pop-up function" in ExtJS via the widget.window.
I've created a button in HTML and a pop-u in a JS file, when I click it, everything works fine, the pop-up is well displayed.
The HTML button is coded this way :
<input type="button" id="popup-map" value="Pop Up"/>
And the JS refers to the button this way :
Ext.application({
name: 'popup',
launch: function() {
var popup,
button = Ext.get('popup-map');
button.on('click', function(){
if (!popup) {
popup = Ext.create('widget.window', {
title: 'Pop-Up',
header: {
titlePosition: 2,
titleAlign: 'center'
},
border: false,
closable: true,
closeAction: 'hide',
width: 800,
minWidth: 400,
maxWidth: 1200,
height: 500,
minHeight: 550,
maxHeight: 800,
tools: [{type: 'help'}],
layout: {
type: 'border',
padding: 2
},
items: [
{
region: 'center',
xtype: 'tabpanel',
items: [
mappanel,
{
title: 'Description',
html: 'Attributs de l\'objet sous forme de tableau'
}
]
}
]
});
}
button.dom.disabled = true;
if (popup.isVisible()) {
popup.hide(this, function() {
button.dom.disabled = false;
});
} else {
popup.show(this, function() {
button.dom.disabled = false;
});
}
});
Problem, if I have two buttons that contains the id "popup-map", only the first one declared is working. I guess it's pretty normal the way I've coded it.
How can I call the popup contains in the JS file by clicking several buttons in HTML ?
Thanks :-)
Use a CSS class instead of a duplicated id. Duplicated ids are bad, you know that... Then use Ext.query instead of Ext.get. Your code should look something like this:
Ext.onReady(function() {
var popup;
function handler(button) {
if (!popup) {
// ...
}
// you've got button and popup, do your things
}
// adds the handler to every button with class 'popup-map' on the page
Ext.query('button.popup-map', function(button) {
button.on('click', handler);
});
});
I'm using Ext.onReady to wait for the DOM to be ready before searching for buttons on the page. That also gives us a closure for our local variables popup and handler.
Thanks to #rixo, here's the code working.
I've created a empty css class called customizer.
Ext.onReady(function() {
var popup, popup_visible;
function popup_constructor() {
//alert(this.getAttribute('pwet'));
if (!popup) {
popup = Ext.create('widget.window', {
title: 'Pop-Up',
id: 'popup',
header: {
titlePosition: 2,
titleAlign: 'center',
height: 30
},
border: false,
closable: true,
closeAction: 'hide',
width: 800,
minWidth: 400,
maxWidth: 1200,
height: 500,
minHeight: 550,
maxHeight: 800,
tools: [{type: 'help'}],
layout: {
type: 'border',
padding: 10
},
items: [
{
region: 'center',
xtype: 'tabpanel',
plain: true,
items: [
{
title: 'Carte',
html: 'On mettra la carte ici',
border: false,
},
{
title: 'Description',
html: 'Attributs de l\'objet sous forme de tableau',
border: false,
}
]
}
]
});
}
popup_visible = true;
if (popup.isVisible())
{
popup.hide(this, function() {
popup_visible = false;
});
}
else
{
popup.show(this, function() {
popup_visible = false;
});
}
}
var popup_show = Ext.query('.customizer');
Ext.each(popup_show, function (item) {
item = Ext.get(item);
item.on('click', popup_constructor);
}, this);
});

I am using an awesome html2canvas function but I have a noob question. How do I change the field it is capturing from document.body to a specific panel?
In short i need to change document.body to the panel I want to capture, I just don't know the code to get the panel I want.
I have tried Ext.ComponentQuery.query('#testPanel') without any success.
testButtonClicked: function (btn) {
html2canvas(document.body, {
onrendered: function (canvas) {
new Ext.Window({
title: 'Screenshot',
//width: 500,
height: 800,
resizable: true,
autoScroll: true,
preventBodyReset: true,
html: '<img src="' + canvas.toDataURL("image/png") + '" height="800"/>'
}).show();
}
});
You want getEl().dom. Here's a standalone example (tested with Ext 4.2.x):
Ext.onReady(function () {
Ext.define('Panel', {
extend: 'Ext.panel.Panel',
frame: true,
title: 'Test Panel',
width: 300,
height: 300,
onClick: function () {
html2canvas(this.getEl().dom, {
onrendered: function (canvas) {
new Ext.Window({
title: 'Screenshot',
width: 300,
height: 300,
html: '<img src="' + canvas.toDataURL("image/png") + '"/>'
}).show();
}
});
},
initComponent: function () {
var config = {
items: [
{
xtype: 'datepicker'
},
{
xtype: 'button',
text: 'CAPTURE THIS PANEL',
handler: this.onClick,
scope: this
}
]
};
Ext.apply(this, Ext.apply(this.initialConfig, config));
this.callParent(arguments);
}
});
var panel = Ext.create('Panel', {
renderTo: Ext.getBody()
});
});
html2canvas() appears to require a DOM element. Ext.ComponentQuery.query() returns an array of matched elements, so if you use precisely the code you provided, it won't work since the array returned from query() is obviously not a DOM element.
So if query() is actually returning something, you could use the first position:
Ext.ComponentQuery.query("#testPanel")[0]
Or, since you seem to have an ID assigned to the panel, you could simply use getCmp(), which will return only the element which is matched, and not an array:
Ext.getCmp( "testPanel" )
I have added an input field to Window's title bar (header). On Chrome selecting and editing the input field works, and I can still drag the window around. On Firefox I can drag the window around the viewport, but I am unable to select the input field and edit it. How should I correct this code so that it would work on both browsers?
Quick'n'dirty demonstration of the problem:
Ext.define('Demo.DemoWindow', {
extend: 'Ext.window.Window',
xtype: 'demowindow',
height: 300,
width: 400,
title: 'Window',
autoShow: true,
items: [{
xtype: 'button',
text : 'Press!',
listeners: {
click: function() {
var win = this.up('window');
var header = win.getHeader();
header.setTitle('');
var killDrag = false;
var dragEvent = win.dd.on({
beforedragstart: function(dd, e) {
if (killDrag) {
return false;
}
}
});
var field = Ext.create('Ext.form.field.Text', {
name: 'Title',
allowBlank: false,
value: 'Type here something!',
listeners: {
el: {
delegate: 'input',
mouseout: function() {
killDrag = false;
},
mouseenter: function() {
killDrag = true;
}
}
}
});
header.insert(0, field);
}
}
}]
});
Ext.application({
name: 'Demo',
launch: function() {
Ext.create('Ext.container.Viewport', {
layout: 'absolute',
items: [
{
xtype: 'demowindow',
x: 20,
y: 20,
}
]
});
}
});
Using the mouseover event instead of mouseenter seems to work well with both.
In My Sencha touch 2.0 app I am having an issue with a JW javascript video player not playing when there are two overlays up at the same time and I wanted to see if anyone could better elaborate on what is going wrong or what may be causing it so I can try and look around and try to figure out what is going on (i am new to sencha and javascript). I have the project loaded up at http://www.cox7.com/sean even tho it will only be run on an iPad.
Try the steps below to better see what I am talking about and also note that a lot of the jwplayer events are being logged in the javascript console so you can see whats going on......
1) click on any of the panels on the main page which will open a overlay with the video title description and a javascript video player. You will see that you can play the video.
2) do a search for "stem" in the search bar (top right corner of the main screen) this will then display a pannel with the search results.
3) click on any of the search results which will then open that same video player pannel but this time you will not be able to click the play button. It's almost like the pannel is not the top most element but I can still scroll and the onTouchStart event fires but the video never starts.
Anyone know what might be causing this? any help is much appreciated.
Here is my controller setup for the search result overlay....
showStreamSearchPopup: function showStreamPopup(list, index, node, record) {
//alert(record.get('title'));
//var record = getData().getStore().getAt(index);
StreamVideoSearchPlayerOverlay = Ext.Viewport.add({
xtype: 'panel',
modal: true,
hideOnMaskTap: true,
showAnimation: {
type: 'popIn',
duration: 200,
easing: 'ease-out'
},
hideAnimation: {
type: 'popOut',
duration: 200,
easing: 'ease-out'
},
centered: true,
width: '78%',
height: '68%',
styleHtmlContent: true,
listeners: {
painted: function() {
console.log('StreamVideoSearchPlayerOverlay painted');
},
activeitemchange :function() {
console.log('StreamVideoSearchPlayerOverlay activeitemchange');
}
},
items: [{
style: 'padding:1em;',
html:[ "<div class=\"postTitle\">",record.get('title'),"</div><div class=\"postDate\">Added on ",
record.get('date'),"</div><div class=\"postDesc\">",record.get('content'),"</div>"
].join("")
},
{
xtype: 'panel',
layout: 'card',
cls: 'videoPlayeriPad',
items:[{
xtype: 'jwplayer',
playerOptions: {
file: record.get('ipadvideo'),
image: record.get('poster'),
width: 500,
height: 281,

}
}]
}
],
scrollable: true
}
);
StreamVideoSearchPlayerOverlay.show();
StreamVideoSearchPlayerOverlay.setActiveItem(2);
},
And here is my controller setup for the normal home screen asset overlay...
showStreamPopup: function showStreamPopup(list, index, node, record) {
//alert(record.get('title'));
//var record = getData().getStore().getAt(index);
StreamVideoPlayerOverlay = Ext.Viewport.add({
xtype: 'panel',

hideAnimation: {

easing: 'ease-out'
},

width: '78%',
height: '68%',
styleHtmlContent: true,
listeners: {
painted: function() {
console.log('StreamVideoPlayerOverlay painted');
},
activeitemchange :function() {
console.log('StreamVideoPlayerOverlay activeitemchange');
}
},
items: [{
style: 'padding:1em;',
html:[ "<div class=\"postTitle\">",record.get('title'),"</div><div class=\"postDate\">Added on ",
record.get('date'),"</div><div class=\"postDesc\">",record.get('content'),"</div>"
].join("")
},
{
xtype: 'panel',

I want to add buttons in one of columns in the grid. I try this code
listeners: {
render: {
fn: function(kad_tab){
var view = kad_tab.getView();
for (var i = 0; i < store.getCount(); i++) {
var cell = Ext.fly(view.getCell(i, 2));
new Ext.Button({
handler: function(){
alert('Suppression')
},
renderTo: cell.child(".btn"),
text: 'Supprimer'
});
}
},
// delay: 200
}
}
{header: "", width: 70, dataIndex: '', renderer: function(){ return '<div class="btn" style="height: 11px; width: 60px"></div>';}}
But firebug says that he see error here Ext.fly(this.getRow(c)) is null.
if i use delay: 200. There is no errors in firebug but dont see a buttons in column.
What im doing wrong?
I found a simple way...
{
xtype: 'actioncolumn',
width: 50,
items: [{
icon : url_servlet+'externals/gxp/src/theme/img/pencil.png',
tooltip: 'Button click',
handler: function(grid, rowIndex, colIndex) {
alert("DAMACIA!!!!!");
}
}]
}
I have a Panel with two buttons that is used inside another panel. Right now it renders the buttons correctly but I'd like to add a margin between them. How to configure layout properly to get this ?
return Ext.create('Ext.panel.Panel', {
width: 220,
height: 35,
border: false,
collapsible: false,
renderTo: renderTo,
items : [
{
xtype: 'button',
scale: 'medium',
text: this.exportButtonText,
handler: function() {
var form = this.form.getForm();
if (form.isValid()) {
var values = form.getValues();
form.reset();
this.plugin.printSettings = values;
this.progressBar.show();
this.plugin.doPrint();
}
},
scope: this
},
{
xtype: 'button',
scale: 'medium',
text: this.cancelButtonText,
handler: function() {
me.close();
},
scope: this
}
]
});
Or add this to left button definition:
{
margin: '0 5px 0 0'
}
Add this in between them:
{
xtype: 'tbspacer',
flex: 1
}
