Common form with Ext.direct submit n load, load is working properly, but submit is return error, coz in post data in undefined
var _form = Ext.create('Ext.form.Panel', {
api: {
submit: submit, //actions I took from code that going above, and never mind what I ll write here. Its not a problem
load: load
},
baseParams: {
st_id: st_id,
id: id
},
paramsAsHash: true,
defaultType: 'textfield',
buttons: [{
text: 'Cancel',
handler: function() {
this.up('form').getForm().reset();
}
}, {
text: 'Save',
handler: function() {
var values = this.up('form').getForm().getValues();
this.up('form').getForm().submit({
success: function() {
grid.getStore().load();
}
});
this.up('form').getForm().reset();
}
}]
});
in to headers wrote that content type is "application/json;" but in other cases its "application/x-www-form-urlencoded", last it make sense, right? and it work, but in other forms.
all of this is under Kohana, so when I look clearly what is going on in controllers, in Extdirect Router I see what for this form there is no info about submit method.
it was kind of stupid mistake: I forgot #formHandler in a definition

In my application, I have a log in window with two textfields (email and password) and submit button that submits those values to the server:
doLogin: function() {
var me = this,
form = me.lookupReference('form');
me.getView().mask('Authenticating... Please wait...');
form.submit({
clientValidation: true,
url: 'login.php',
scope: me,
success: 'onLoginSuccess',
failure: 'onLoginFailure'
});
},
I would like have an option ‘remember me on this device’ in login window, so the user doesn’t need to input credentials every time. My idea was to use cookies to store values for email and password.
So, I added a checkbox in login form, and upon successful log in, if checkbox is checked, I save email in cookie:
Ext.util.Cookies.set('MyApplication', user_email);
And the same I do for the password. Those cookies can be cleared on logout. At the very beginning of the application I can read those cookies
Ext.util.Cookies.get('MyApplication');
That could be done at the very beginning or for example on ‘beforerenderer’ event of login window.
But now comes the part when I should skip appearance of login window if the user selected that option. Actually, I don’t want to skip that window at all – I would just like to hide it and to maintain its actions.
So, is it possible at some place to add something like
if (Ext.util.Cookies.get('MyApplication')){
// 1. hide the login window so it won't appear at all
// 2. Set value of email and password textfields to stored values
// 3. Submit such hidden form to the server
}
You can set hidden in beforerender event and submit the form, in this case user will not see it (it will be rendered in hidden mode):
Ext.application({
name: 'Fiddle',
launch: function () {
Ext.create('Ext.form.Panel', {
title: 'Simple Form',
bodyPadding: 5,
width: 350,
// The form will submit an AJAX request to this URL when submitted
url: 'save-form.php',
// Fields will be arranged vertically, stretched to full width
layout: 'anchor',
defaults: {
anchor: '100%'
},
// The fields
defaultType: 'textfield',
items: [{
fieldLabel: 'Email',
name: 'email',
value: Ext.util.Cookies.get('email'),
allowBlank: false
}, {
fieldLabel: 'password',
name: 'password',
allowBlank: false,
inputType: 'password',
value: Ext.util.Cookies.get('password')
}],
// Reset and Submit buttons
buttons: [{
text: 'Reset',
handler: function () {
this.up('form').getForm().reset();
}
}, {
text: 'Submit',
formBind: true, //only enabled once the form is valid
disabled: true,
handler: function () {
var form = this.up('form').getForm();
if (form.isValid()) {
form.submit({
success: function (form, action) {
Ext.Msg.alert('Success', action.result.msg);
},
failure: function (form, action) {
Ext.Msg.alert('Failed', action.result.msg);
}
});
}
}
}],
listeners: {
beforerender: function(loginWindow) {
if(Ext.util.Cookies.get('email') && Ext.util.Cookies.get('password')) {
console.log('Hidden');
loginWindow.setHidden(true);
loginWindow.getForm().submit();
}
}
},
renderTo: Ext.getBody()
});
}
});
When I load a store, due to the API structure, I get a json object inside my model:
Ext.define('TestApp.model.SecretKeyModel', {
extend: 'Ext.data.Model',
config:{
identifier: {
type: 'uuid'
},
fields: [
{ name:'theRecord', type:'json' }
]
},
extractToken: function() {
var record = this;
var token = record.initSession.token;
console.log('token: ' + token);
}
});
I need to extract the token from that json object.
For that, i think I should write a function right there, inside the model.
How can I call it, when the store loads, to manipulate the data and extract the token?
I faced a similar situation 1 hour ago, i needed to edit data during loading or immidiatly after. I ended with this solution:
Ext.define('TestApp.store.MyStore', {
extend: 'Ext.data.Store',
requires: ['TestApp.model.SecretKeyModel'],
config :{
model: 'TestApp.model.SecretKeyModel',
proxy: {
type: 'ajax',
url: TestApp.utils.GlobalVariables.getServerUrl(),
reader: {
type: 'json',
rootProperty: ''
}
},
listeners: {
refresh: function(store, data, eOpts) {
store.each(function (item, index, length) {
item.extractToken(); // call this on every record loaded in the store
});
}
}
}
});
I'm trying to upload a file using Ext JS forms and in case of success or failure, show appropriate messages. But I'm not able to get the desired result. I'm not able to make success or failure callbacks work in form.submit action.
What I've done till now is:
Creating a form with this script:
new Ext.FormPanel({
fileUpload: true,
frame: true,
url: '/profiler/certificate/update',
success: function() {
console.log(arguments);
},
failure: function() {
console.log(arguments);
}
}).getForm().submit()
/*
The response Content-Type is text/html (with charcode=utf8);
The response JSON is: { "success": true }
*/
Setting the response Content-Type to text/html based on this answer.
Sending an appropriate JSON result back, based on Ext JS docs. The response captured via Fiddler is:
{"success":false}
or
{"success":true}
I even set the response Content-Type to application/json. But still no success.
I've read links like this and this, but none of them helped. Please note that I also tried another script which creates a form, with an upload field in it, and a save button, and I submitted the form in the handler of the save button. But still no callback is fired.
Here's a working example - Javascript code:
Ext.onReady(function () {
Ext.define('ImagePanel', {
extend: 'Ext.form.Panel',
fileUpload: true,
title: 'Upload Panel',
width: 300,
height: 100,
onUpload: function () {
this.getForm().submit({
url: 'upload.php',
scope: this,
success: function (formPanel, action) {
var data = Ext.decode(action.response.responseText);
alert("Success: " + data.msg);
},
failure: function (formPanel, action) {
var data = Ext.decode(action.response.responseText);
alert("Failure: " + data.msg);
}
});
},
initComponent: function () {
var config = {
items: [
{
xtype: 'fileuploadfield',
buttonText: 'Upload',
name: 'uploadedFile',
listeners: {
'change': {
scope: this,
fn: function (field, e) {
this.onUpload();
}
}
}
}
]
};
Ext.apply(this, Ext.apply(this.initialConfig, config));
this.callParent(arguments);
}
});
var panel = Ext.create('ImagePanel', {
renderTo: Ext.getBody()
});
});
And PHP code:
<?php
if (isset($_FILES)) {
$temp_file_name = $_FILES['uploadedFile']['tmp_name'];
$original_file_name = $_FILES['uploadedFile']['name'];
echo '{"success": true, "msg": "'.$original_file_name.'"}';
} else {
echo '{"success": false, "msg": "No Files"}';
}
I have been struggling with this for quite some time now as well. Here's my code:
Ext.getCmp('media-upload-form').getForm().doAction('submit', {
url: './services/recordmedia/upload',
method: 'post',
waitMsg: 'Please wait...',
params: {
entityId: this.entityId,
},
failure: function(form, action){
alert(_('Error uploading file'));
this.fireEvent('file-upload');
this.close();
},
success: function(form, action){
this.fireEvent('file-upload');
this.close();
},
scope: this
})
The response was always wrapped in <pre> tags by the browser, what caused the Extj lib not to call the callbacks. To fix this:
make sure your server returns the correct json: {"success":true}
make sure that the content-type is set to text/html
Actually, this is well covered by docs for Ext.form.Panel and Ext.form.Basic. The problem with your code not working is that there are no config options "success", "failure" for the form panel. You should put them in the config object passed to the submit action. So your code should look like:
new Ext.FormPanel({
fileUpload: true,
frame: true
}).getForm().submit({
url: '/profiler/certificate/update',
success: function() {
console.log(arguments);
},
failure: function() {
console.log(arguments);
}
});
Note the difference: In Ext 4, there is a form component (Ext.form.Panel) which is basically a view component concerned with how you form looks, and then there is the underlying form class (e.g. Ext.form.Basic) concerned with the functionality. Form submissions are handled by Ext.form.Basic (or whatever returned by your form.getForm()).
I'm developing a simple form with Secha Touch. I have defined a DataStore for my model like this:
App.stores.shopinglists = new Ext.data.Store({
model: 'ShopingList',
autoLoad: false,
proxy: new Ext.data.AjaxProxy({
type: 'ajax',
url: 'http://localhost:2795/ShopingListService/',
reader: {
type: 'json',
root: 'ResultData',
totalProperty: 'Total',
successProperty: 'Success'
},
writer: {
encode: true,
type: 'json'
}
})
});
The view loads fine, and I can see a list of items and edit them. However, when I click the update button, I get the following error:
Uncaught Error: You are using a ServerProxy but have not supplied it with a url.
What I am missing here? The proxy has the url defined, but when update is invoked, it's undefined.
Edit: The button just call a controller action.
onSaveAction: function () {
var model = this.getRecord();
Ext.dispatch({
controller: 'ShopingLists',
action: (model.phantom ? 'save' : 'update'),
data: this.getValues(),
record: model,
form: this
});
},
The code executed by the controller is this:
update: function (params) {
debugger;
var tmpshopingList = new App.models.ShopingList(params.data);
var errors = tmpshopingList.validate();
if (errors.isValid()) {
params.record.set(params.data);
params.record.save();
this.index();
} else {
params.form.showErrors(errors);
}
},
I think I know what is happening: The model knows it has a server proxy, but all of the configurations are not being copied over. Perhaps this is a bug with Sencha Touch 1.x.
Try putting the proxy configuration into your model, not your store.
I have a list of news in a Ext.List inside a panel
prj.views.NewsList = Ext.extend(Ext.Panel, {
layout: 'card',
initComponent: function() {
this.list = new Ext.List({
itemTpl: '......',
loadingText: false,
store: new Ext.data.Store({
model: 'News',
autoLoad: true,
proxy: {
type: 'ajax',
url: '.....',
reader: {
type: 'json',
//root: ''
}
},
listeners: {
load: { fn: this.initializeData, scope: this }
}
})
});
this.list.on('render', function(){
this.list.store.load();
this.list.el.mask('<span class="top"></span><span class="right"></span><span class="bottom"></span><span class="left"></span>', 'x-spinner', false);
}, this);
this.listpanel = new Ext.Panel({
items: this.list,
layout: 'fit',
listeners: {
activate: { fn: function(){
this.list.getSelectionModel().deselectAll();
Ext.repaint();
}, scope: this }
}
})
this.items = this.listpanel;
prj.views.NewsList.superclass.initComponent.call(this);
},
});
Ext.reg('newsList', prj.views.NewsList);
In a toolbar setup in a dockedItem, I have a icon to refresh the list.
items: [
{
iconCls: 'refresh',
handler: function() {
prj.view.NewsList.list.store.read()
}
},
]
but prj.view.NewsList return undefined! How can I get the list to do a refresh of the store?
Call this line on your refresh button
Ext.StoreMgr.get('newsStore').load()
The list is automaticaly refresh when you call the load() method on the store. The store is linked to the list.
Example:
items: [
{
iconCls: 'refresh',
handler: function(event, btn) {
Ext.StoreMgr.get('newsStore').load();
}
},
]
Even I faced a similar problem.
I am posting my answer hope this helps someone.
I have a search bar in to search data. (my search is taking place at server and the results are sent back to me in response to my GET request.
Basically I just had to change the URL for my store
WHAT ALL I TRIED:
myList.refresh(),
myStore.load();
clearing the store and then loading it
removing the list and adding it again and forcing it to re render (using doLayout())
Nothing worked...
just adding SINGLE line fixed my problem
function handleSearch(strSearchText)
{
//myStore.loadData([],false); /tried to clear the store and reloading it
if(strSearchText !='')
{
searchString = '?search='+strSearchText;
searchURL = searchURLBasic+ searchString;
}else{
searchURL = searchURLBasic;
}
console.log('search URL: ' + searchURL);
myStore.proxy.url =searchURL; // this was one magical line of code that saved my life
myStore.load();
}
THanks SO for support.
I do this when changing the store and it works like a champ
var yourbutton = new Ext.Panel({
listeners: {
afterrender: function(c){
c.el.on('click', function(){
YourList.update();
YourList.bindStore(newStore);
});
}
}
});
