I have a form field and i want to read the text entered into it, i tried the following code:
this.searchButton = new Ext.Button({// The button press will invoke the search action
text: 'Go',
handler: this.searchButtonTap,
scope: this
});
this.topToolbar = new Ext.form.FormPanel({
items: [
{xtype: 'textfield',
name: 'search',
placeHolder: 'Search'},
this.searchButton
]
});
searchButtonTap: function () {
// console.log(this.topToolbar.items.items[1]);
var currentText = AsApp.views.AsListView.getRecord();
console.log(currentText);
},
you may try this:
this.searchField = new Ext.form.Text({
displayField: 'name',
valueField: 'name',
editable: true,
forceSelection: true,
triggerAction: 'all',
emptyText: 'Search...',
selectOnFocus: true
});
this.searchButton = new Ext.Button({// The button press will invoke the search action
text: 'Go',
handler: this.searchButtonTap,
scope: this
});
this.topToolbar = new Ext.Toolbar({
items: [
{ xtype: 'spacer' },
this.searchField,
this.searchButton,
{ xtype: 'spacer' },
]
});
searchButtonTap: function () {
var searchText = this.searchField.getValue();
console.log(searchText);
},
To get the value of a textfield, use the field's getValue() method.
For example:
var field = myTextField;
var currentText = field.getValue();
You can also use searchfield instead of textfield. It also has the getValue() method available.

i have a form A containing some fields about questions(a model in my application),but it can not submit directly by form.getForm().submit().the buttons in form A will open another window,and a field on that window.i want to attach the field to form A ,so i can submit those fields together.
the detail is as follows:
enter image description here
In this case, I would try to give two different ID's to forms. Next, retrieve the values from them and merge If the field names are different.
var first_form_values = Ext.getCmp('first-form').getForm().getValues();
var second_form_values = Ext.getCmp('second-form').getForm().getValues();
var all_values = Ext.Object.merge(first_form_values , second_form_values);
Then you have all the values and you can send them by Ext.Ajax etc.
Full example:
Ext.create('Ext.window.Window', {
title: 'First Form',
height: 200,
width: 400,
layout: 'fit',
items: {
xtype: 'form',
id: 'first-form',
items: [
{
xtype: 'textfield',
fieldLabel: 'First field',
name: 'first-field',
}
]
},
buttons: [
{
text: 'Show second form'
handler: function()
{
Ext.create('Ext.window.Window', {
title: 'Second Form',
height: 200,
width: 400,
layout: 'fit',
items: {
xtype: 'form',
id: 'second-form',
items: [
{
xtype: 'textfield',
fieldLabel: 'Second field',
name: 'second-field',
}
]
},
buttons: [
{
text: 'Submit'
handler: function()
{
var first_form = Ext.getCmp('first-form'),
second_form = Ext.getCmp('second-form');
if(first_form && second_form)
{
var fist_form_values = first_form.getForm().getValues(),
second_form_values = second_form.getForm().getValues();
var values = Ext.Object.merge(fist_form_values, second_form_values);
// You have all values from two forms
}
}
}
]
}).show();
}
}
]
}).show();
I'm trying to add a combobox to a floating (popup) form panel in ExtJS. But I'm getting a "Cannot set property 'component' of null" error and the window will not load.
I use the following code in a controller to create the window:
onTreeAddDocClick: function () {
var f = new Ext.form.Panel({
frame: false,
header: false,
floating: true,
closable: true,
items: [{
xtype: 'addDoc'
}]
});
f.show();
}
The code for the window itself is as follows:
Ext.define('OPENhrm.view.dossier.widget.popup.AddDoc', {
extend: 'Ext.form.Panel',
xtype: 'addDoc',
requires: [
'Ext.layout.container.VBox'
],
controller: "dossier-addDoc",
viewModel: {
type: "dossier-addDoc"
},
id: 'addDocForm',
frame: true,
title: 'Add document',
width: 400,
bodyPadding: '10 10 0',
layout: 'form',
closable: true,
defaults: {
anchor: '100%',
allowBlank: false,
msgTarget: 'side',
labelWidth: 50
},
items: [{
// item selector
xtype: 'filefield',
emptyText: 'Select Document',
fieldLabel: 'Document',
name: 'filePath',
id: 'filePath',
buttonText: 'upload document',
buttonConfig: {
icon : '/resources/images/icons/add.jpg'
}
}, {
xtype: 'combo',
fieldLabel: 'Test',
hiddenName: 'test',
store: new Ext.data.SimpleStore({
data: [
['Test1'],
['Test2']
],
id: 0,
fields: ['text']
}),
valueField: 'text',
displayField: 'text',
triggerAction: 'all',
editable: false
}],
// buttons
buttons: [{
text: 'Add',
handler: 'onAddDockClick'
}, {
text: 'Reset',
handler: function () {
this.up('form').getForm().reset();
}
}]
});
If I remove the combobox, the window works just fine. If I place the combobox in a form somewhere else in my application (e.g. on a page with 2 panels; a searchfilter/form and a grid with search results), it works just fine. That other page however, is not a floating/popup window.
I got it to work by defining the whole page in the controller, but as I'm using a MVC structure, that doesn't seem like the way to go. Does anyone know how to get the combobox to work in a floating window, without putting the whole code for that window in the controller?
I have several tabs on toolbar each of them having seperate handler , i have called seperate function of each handler . The code is as below
Ext.define('myco.view.User', {
extend: 'Ext.Container',
config: {
scrollable: true,
items: [{
xtype: 'panel',
id: 'User'
},
{
docked: 'top',
xtype: 'toolbar',
items: [{
text: 'My Profile',
handler: function() {
var panel = Ext.getCmp('User'),
tpl = new Ext.XTemplate([
'<div class="demo-weather">',
'<tpl for=".">',
'<div class="day">',
'<div class="date">{username}</div>',
'<tpl for="weatherIconUrl">',
'<img src="{value}">',
'</tpl>',
'<span class="temp">{tempMaxF}°<span class="temp_low">{tempMinF}°</span></span>',
'</div>',
'</tpl>',
'</div>'
]);
panel.getParent().setMasked({
xtype: 'loadmask',
message: 'Loading...'
});
Ext.Ajax.request({
url: 'http://localhost:8000/api/myapp/user/',
method:'GET',
callbackKey: 'callback',
defaultHeaders : 'application/json',
params: {
//key: '23f6a0ab24185952101705',
//q: '94301', // Palo Alto
format: 'json',
//num_of_days: 5
},
success : function(response, opt) {
dataarray = Ext.decode(response.responseText);
weather=dataarray.objects;
panel.updateHtml(tpl.applyTemplate(weather))
panel.getParent().unmask();
},
failure : function(response, opt) {
Ext.Msg.alert('Failed', response.responseText);
panel.getParent().unmask();
}
});
}
},
{
text:'login',
handler: function() {
var main = new Ext.Panel({
title: 'My first panel', //panel's title
fullscreen: true,
//the element where the panel is going to be inserted
//html: 'Nothing important just dummy text' //panel's content
items:[
{
xtype: 'fieldset',
title: 'Login',
items: [
{
xtype: 'textfield',
label: 'Username',
name: 'username',
id : 'username'
},
{
xtype: 'passwordfield',
label: 'Password',
name: 'password',
id : 'password'
}
]
},
{
xtype: 'button',
text: 'Send',
ui: 'confirm',
handler: function() {}
}
]
});
panel.add(main);
alert('test');
}
}
]
}]
}
});
Now when i click on the tab , previous panel will not be cleared and data will get overlapped there ..... like when i click My profile profile is listed there , after that when i click login profile+ login both will be loaded one overlapping another ...
You should use Ext.tab.Panel for this, define your profile and login panels as items of a parent TabPanel, the switching will be handled by ExtJS. You can use the activate event of a Panel to add custom logic to execute when your tabs get activated.
I am new to ExtJS 4 and am trying to implement a simple application in MVC style. The documentation is really good and this is one of the topics covered in the Form package guide, but it doesn't seem to work in my case.
The app basically can create, edit and delete articles.The creation and editing are in pop-up windows.
The pop-up window contains a form with a text field and html-editor.
Please click on the link below,this is the error in Google Chrome Console when I click on the submit button in the 'window'
http://www.freeimagehosting.net/mjig7
Here is the code which I've written
Model:
Ext.define('AM.model.Article', {
extend: 'Ext.data.Model',
fields: ['name', 'data'],
proxy: {
type: 'rest',
url: 'users/data',
reader: {
type: 'json',
root: 'myJaxBean',
successProperty: 'success'
},
writer: {
type: 'json'
}
}
});
View:
Ext.define('AM.view.New', {
extend: 'Ext.window.Window',
alias : 'widget.new',
title : 'New Article',
autoShow: true,
fieldDefaults: {
labelAlign: 'top',
msgTarget: 'side'
},
layout: 'fit',
bodyStyle:'padding:5px 5px 0',
width: '70%',
height: '40%',
initComponent: function() {
this.items = [
{
xtype: 'form',
anchor: '99%',
items: [
{
xtype: 'textfield',
name : 'name',
fieldLabel: 'Article Name',
anchor: '99%'
},
{
xtype: 'htmleditor',
name : 'data',
fieldLabel: 'Article',
anchor: '99% -25'
}
],
buttons: [
{
text: 'Submit',
handler: function() {
var form = this.up('form').getForm(), // get the basic form
record = form.getRecord(); // get the underlying model instance
if (form.isValid()) { // make sure the form contains valid data before submitting
form.updateRecord(record); // update the record with the form data
record.save({ // save the record to the server
success: function(user) {
Ext.Msg.alert('Success', 'User saved successfully.')
},
failure: function(user) {
Ext.Msg.alert('Failure', 'Failed to save user.')
}
});
} else { // display error alert if the data is invalid
Ext.Msg.alert('Invalid Data', 'Please correct form errors.')
}
}
},
{
text: 'Cancel',
scope: this,
handler: this.close
}
]
}
],
this.callParent(arguments);
}
});
and finally the code in my controller which makes the window visible
Controller:
.....
'viewport > panel > panel > tbar button[action=newarticle]' :{
click: this.newArticle
},
....
newArticle: function(button){
var view = Ext.widget('new');
},
Please point me in the right direction in case I am doing something wrong.
Thanks in advance.
Check the docs getRecord():
Returns the last Ext.data.Model instance that was loaded via
loadRecord
so it's clear that you haven't load any record, so you getRecord() returns undefined. And you are getting your error further.
thats weired - it worked and suddenly (changed nothing but adding code to other panels...) it's not working any more:
I used to enable/disable a form with a button inside a docked toolbar. within the handler ofthe button the disable/enable is triggered with a simple
formBase.enable();
but this is throwing the error
TypeError: Result of expression 'formBase.enable' [undefined] is not a
function.
now.
I don't get it....
any help would be great!
thx!
You probabilly have a scope issue, so you can't get your formBase variable from the button handler.
I post you a full working example I've done to let you understand how it is possible to enable / disable your form.
Ext.setup({
onReady: function() {
var form = new Ext.form.FormPanel({
scroll: 'vertical',
fullscreen: true,
url : 'postUser.php',
standardSubmit : false,
dockedItems: [{
xtype: 'toolbar',
title: 'Example',
items: [{
xtype: 'button',
text: 'Disable',
handler: function(){
form.disable();
}
},{
xtype: 'spacer'
},{
xtype: 'button',
text: 'Enable',
handler: function(){
form.enable();
}
}]
}],
items: [{
xtype: 'fieldset',
title: 'Personal Info',
instructions: 'Please enter the information above.',
defaults: {
required: true,
labelAlign: 'left',
labelWidth: '40%'
},
items: [
{
xtype: 'textfield',
name : 'name',
label: 'Name',
useClearIcon: true,
autoCapitalize : false
}, {
xtype: 'passwordfield',
name : 'password',
label: 'Password',
useClearIcon: false
}]
}]
});
form.show();
}
});
Hope This helps.
