I am trying to create a list of links from a data store, and then use an XTemplate to loop through and display all the links in the data store. I am trying to display the links in a modal window. This is my code:
var win;
var tpl = new Ext.XTemplate("<p>Field1: {f1}, Field2: {f2} </p>").compile();
var data = {
f1: 'a',
f2: null
};
if(!win){
win = new Ext.Window({
el:'hello-win',
layout:'fit',
width:500,
height:300,
closeAction:'hide',
plain: true,
items: [
{
xtype: 'component',
autoEl: {
html: '<input type="text">'
},
listeners: {
render: function(_component) {
_component.getEl().on('keyup', function(e) {
//console.log(this);
console.log(this.dom.childNodes[0].value);
});
}
}
},
{
xtype: 'panel',
title: 'test',
height: 100,
bodyPadding: 10,
tpl: tpl,
data: data,
renderTo: Ext.get('hello-win')
}
]
});
}
win.show(this);
There are no errors in console, but the links never load. It just shows my modal window and my textbox, but no links. I would put in in a jsfiddle, but I don't know how (I'm new to ExtJs).
How can I display a list of links in this modal window?
You should not define renderTo in you panel config. Component defined in items array will be rendered to parent component automatically.
Your window have two items so you can not use fit layout. This layout can be used only if component have only one child component. You can remove layout definition and Ext JS framework will use auto layout or you can use some layout which support more child items, like hbox, vbox, etc.
Your code should look like this:
var win = new Ext.Window({
width:500,
height:300,
closeAction:'hide',
plain: true,
items: [
{
xtype: 'textfield',
enableKeyEvents: true,
listeners: {
keyup: function(c) {
console.log(c.getValue());
}
}
},
{
xtype: 'panel',
title: 'test',
height: 100,
bodyPadding: 10,
tpl: tpl,
data: data
}
]
});
Also you should consider using textfield component instead of creating textfield by using component with autoEl config.

I have some problems with Extjs 4.1.1 while using loading mask.
I have created a custom window and on a button press it sets the loading mask
var options=Ext.create('Ext.window.window',{
title:'this window',
height:200,
width:100,
items: { // Let's put an empty grid in just to illustrate fit layout
xtype: 'grid',
border: false,
columns: [{header: 'World'}],
store: Ext.create('Ext.data.ArrayStore', {}) // A dummy empty data store
}
}).show();
options.setLoading('Loading...');
After the load mask is enabled,if I open another window the mask is displaced from its place which is not desirable.
How should I prevent other windows from affecting the loading mask.
Or should I put mask over the entire frame instead of just the window?
If creating duplicate windows are neccesarry, you can check the window is created before. If it exits, do not need to setLoading. Look at this: https://fiddle.sencha.com/#fiddle/tv5
var me = this;
var x = 50;
var button = Ext.create('Ext.button.Button', {
text: 'click',
renderTo: Ext.getBody(),
closable: true,
handler: function() {
me.options = Ext.create('Ext.window.Window',{
title:'this window',
height:200,
width:400,
items: { // Let's put an empty grid in just to illustrate fit layout
xtype: 'panel',
html: 'here' // A dummy empty data store
}
});
me.options.show();
me.options.setXY([x+30, x+30]);
me.options.mask('Loading1...');
}
});
var button2 = Ext.create('Ext.button.Button', {
text: 'click',
renderTo: Ext.getBody(),
closable: true,
handler: function() {
me.options2 = Ext.create('Ext.window.Window',{
title:'this window',
height:200,
width:400,
items: { // Let's put an empty grid in just to illustrate fit layout
xtype: 'panel',
html: 'here' // A dummy empty data store
}
});
me.options2.show();
me.options2.setXY([x+200, x+300]);
me.options2.mask('Loading2...');
}
});
I just started using ExtJS 3.4 version. And I was not sure how to access the items within the panel when there is no id or itemId assigned to it. I have used Ext JS 4.2 before but I need to use 3.4 version for now.
In my case, I am using border layout here. I have a tree panel on the east region and a tabpanel in the center region. And I want to update the center region dynamically with grids or forms based on the tree node clicked.
here is my code for the tabpanel
{
xtype : 'tabpanel',
title : 'Center Panel',
width : 200,
region : 'center',
items:[gridpnl]
}
And here is the complete code that I tried
First ExtJs Page
Ext.onReady(function () {
Ext.namespace('Class');
Class.create = function() {
return this.init(config);
}
};
Ext.namespace('FirstOOPS');
FirstOOPS = Class.create();
FirstOOPS.prototype = {
init: function (config) {
var store= new Ext.data.ArrayStore({
fields: [{name: 'C1'},{ name: 'C3'}, {name: 'C5'}]
});
var myData= [['abcdC11','C3','C5'],['asdf','C3_asdf','C5_asdf']]
store.loadData(myData);
var gridpnl= new Ext.grid.GridPanel({
layout: 'fit',
height: 500,
width: 500,
store: store,
columns:[
{header: "C1", dataIndex: 'C1'},
{header: "C3", dataIndex: 'C3'},
{header: "C5", dataIndex: 'C5' }
]
});
var mainPanel = new Ext.Panel({
layout : 'border',
items : [
{
region: 'east',
collapsible: true,
title: 'Navigation',
xtype: 'treepanel',
width: 200,
autoScroll: true,
split: true,
loader: new Ext.tree.TreeLoader(),
root: new Ext.tree.AsyncTreeNode({
expanded: true,
children: [{
text: 'Grid',
leaf: true
}, {
text: 'Form',
leaf: true
}]
}),
rootVisible: false,
listeners: {
click: function(n) {
if(n.text=='Grid'){
Ext.Msg.alert(n.text);
}
}
}
},{
xtype : 'tabpanel',
title : 'Center Panel',
width : 200,
region : 'center',
items:[gridpnl]
}
]
});
new Ext.Viewport({
layout : 'fit',
items : [mainPanel]
});
}
};
var firstObj = new FirstOOPS();
});
</script>
</body>
</html>
Can someone tell me how to access this without id, so that I can update the tabpanel dynamically or create new tabs based on the tree node click.
Thanks in advance
you can use the following code to access tabpanel without using id or items id
this.up().items.items[1]
to test the above code I am alerting the title of the tab panel by following code
alert(this.up().items.items[1].title);
it will alerts the title of the tab panel
I'm using Ext JS 2.3.0 and have created the search dialog shown below.
The search results are shown in a GridPanel with a single Name column, but notice that this column does not stretch to fill all the available horizontal space. However, after I perform a search, the column resizes properly (even if no results are returned):
How can I make the column display correctly when it's shown initially? The relevant code is shown below:
FV.FindEntityDialog = Ext.extend(Ext.util.Observable, {
constructor: function() {
var queryTextField = new Ext.form.TextField({
hideLabel: true,
width: 275,
colspan: 2,
});
var self = this;
// the search query panel
var entitySearchForm = new Ext.form.FormPanel({
width: '100%',
frame: true,
layout:'table',
layoutConfig: {columns: 3},
items: [
queryTextField,
{
xtype: 'button',
text: locale["dialogSearch.button.search"],
handler: function() {
var queryString = queryTextField.getValue();
self._doSearch(queryString);
}
}
]
});
// the search results model and view
this._searchResultsStore = new Ext.data.SimpleStore({
data: [],
fields: ['name']
});
var colModel = new Ext.grid.ColumnModel([
{
id: 'name',
header: locale['dialogSearch.column.name'],
sortable: true,
dataIndex: 'name'
}
]);
var selectionModel = new Ext.grid.RowSelectionModel({singleSelect: false});
this._searchResultsPanel = new Ext.grid.GridPanel({
title: locale['dialogSearch.results.name'],
height: 400,
stripeRows: true,
autoWidth: true,
autoExpandColumn: 'name',
store: this._searchResultsStore,
colModel: colModel,
selModel: selectionModel,
hidden: false,
buttonAlign: 'center',
buttons: [
{
text: locale["dialogSearch.button.add"],
handler: function () {
entitySearchWindow.close();
}
},
{
text: locale["dialogSearch.button.cancel"],
handler: function () {
entitySearchWindow.close();
}
}
]
});
// a modal window that contains both the search query and results panels
var entitySearchWindow = new Ext.Window({
closable: true,
resizable: false,
draggable: true,
modal: true,
viewConfig: {
forceFit: true
},
title: locale['dialogSearch.title'],
items: [entitySearchForm, this._searchResultsPanel]
});
entitySearchWindow.show();
},
/**
* Search for an entity that matches the query and update the results panel with a list of matches
* #param queryString
*/
_doSearch: function(queryString) {
def dummyResults = [['foo'], ['bar'], ['baz']];
self._searchResultsStore.loadData(dummyResults, false);
}
});
It's the same issue you had in an earlier question, the viewConfig is an config item for the grid panel check the docs , so it should be
this._searchResultsPanel = new Ext.grid.GridPanel({
viewConfig: {
forceFit: true
},
....other configs you need,
To be more precise the viewConfig accepts the Ext.grid.GridView configs, feel free to read the docs on that one too.
Otherwise this seems to be the only problem, and i refer the column width, not the gridpanel width. On the gridpanel you have a title and two buttons who doesn't seem to be affected. So i repeat the gridPanel's width is ok, it's the columns width issue.
Try to remove autoWidth from GridPanel configuration, because setting autoWidth:true means that the browser will manage width based on the element's contents, and that Ext will not manage it at all.
In addition you can try to call .doLayout(false, true) on your grid after it was rendered.
Try to add flex: 1 to your GridPanel
I'm trying to get my test project working and have it set out with various viewports js files for each screen. I have now managed to load the data onto the screen with the code below however I am struggling with trying to set-up the onItemDisclosure function so that it switches to a detailed view which shows more information about the selection item.
MobileApp.views.Settings_screen = Ext.extend(Ext.Panel, {
title: "Settings ",
iconCls: "settings",
fullscreen: true,
layout: 'card',
dockedItems: [{
xtype: "toolbar",
title: "Settings"
}],
initComponent: function() {
detailPanel = new Ext.Panel({
id: 'detailPanel',
tpl: 'Hello, World'
}),
this.list = new Ext.List({
id: 'indexlist',
store: MobileApp.listStore,
itemTpl: '<div class="contact">{firstName} {lastName}</div>',
grouped: false,
onItemDisclosure: function() {
MobileApp.views.setActiveItem('detailPanel');
}
});
this.items = [this.list];
MobileApp.views.Settings_screen.superclass.initComponent.apply(this, arguments);
}
});
Ext.reg('settings_screen', MobileApp.views.Settings_screen);
I have tried to put some code here to switch to the detailPanel but it comes up with an undefined error.
onItemDisclosure: function() {
MobileApp.views.setActiveItem('detailPanel');
}
Thanks Aaron
You need to define this panel under Settings_screen's namespace, like this:
this.detailPanel = new Ext.Panel({
id: 'detailPanel',
tpl: 'Hello, World'
}),
Also, you need to add the detailPanel to the Settings_screen's items, so that it will become an item of it.
this.items = [this.list, this.detailPanel];
I am working with the Sencha touch framework and there list item component. I have only been working with this for about 2 weeks now and I can not figure out how to get the "onItemDisclosure" to open up the "detailPanel". I am trying to follow this example: http://vimeo.com/19245335. I have pasted my code below. Any help is very much appreciated.
GoW3Guide.views.detailPanel = Ext.extend(Ext.Panel, {
id: 'detailpanel',
tpl: 'Hello, {firstName}!',
dockedItems: [
{
xtype: 'toolbar',
items: [{
text: 'back',
ui: 'back',
handler: function() {
GoW3Guide.Viewport.setActiveItem('disclosurelist', {type:'slide', direction:'right'});
}
}]
}
]
});
Ext.reg('detailPanel', GoW3Guide.views.detailPanel);
GoW3Guide.views.listPanel = Ext.extend(Ext.List, {
id: 'disclosurelist',
store: GoW3Guide.ListStore,
itemTpl: '<div class="contact">{firstName} {lastName}</div>',
grouped: true,
onItemDisclosure: function(record, btn, index) {
GoW3Guide.views.detailPanel.update(record.data);
GoW3Guide.views.Guidescard.setActiveItem('detailpanel');
}
});
Ext.reg('listPanel', GoW3Guide.views.listPanel);
GoW3Guide.views.Guidescard = Ext.extend(Ext.Panel, {
fullscreen: true,
layout: 'card',
cardSwitchAnimation: 'slide',
initComponent: function() {
Ext.apply(this, {
items: [GoW3Guide.views.listPanel, GoW3Guide.views.detailPanel]
});
GoW3Guide.views.Guidescard.superclass.initComponent.apply(this, arguments);
}
});
Ext.reg('guidescard', GoW3Guide.views.Guidescard);
Are you getting any javascript errors?
According to the docs setActiveItem either needs a component instance, a number (card index), or a config object, e.g. {xtype:'detailPanel'}
If you want to make a new detail panel active try
GoW3Guide.views.Guidescard.setActiveItem({xtype:'detailpanel'});
or
GoW3Guide.views.Guidescard.setActiveItem(new GoW3Guide.views.detailPanel());
