JsonP request

[terrykoo]

Hi all,

I want to make a json request(calling a web service).
I need to pass three parameters (url,userid,accesskey) to the .php file for validation purpose.

I tried two ways, but both not working for me. The .php file state the parameters didnt passed
Here's my code:

this is my first way:

                                        xtype: 'button',				
					text: 'Accounts',
					handler: function() {
						 Ext.data.JsonP.request({
							url: 'php/vtiger_account.php',
							
							callbackKey: 'callback', 
							
							params: 
							{
								url: url,
								userid: userid,
								accesskey: accesskey
							},
							success: function(result) {
								Ext.getCmp('usermenu').push({		
									title: 'Accounts',
									xtype: 'list',
									store: 'Accountstore',
									itemTpl: '<div>{account_no}</div>{accountname}',
								});
							}
						});
					}

this is my 2nd way:

Ext.define('accountmodel', {
    extend: 'Ext.data.Model',
	
    config: {
        fields: ['accountname','account_no','accounttype','phone']
    }
});


//Store
var accountstore = Ext.create('Ext.data.Store', {			//create data store 'Login1model.js'
    storeId:'Accountstore',
    model: 'accountmodel',
	
	proxy:{
		type:'jsonp',
		url:'php/vtiger_account.php',
		callbackKey:'callback',
                extraParams:{
                    url: url,
                    userid: userid,
                    accesskey: accesskey
                }


		reader:{
			type:'json'
		},
	}
});


Ext.define('SCM.view.Account', {
	extend: 'Ext.navigation.View',
	xtype: 'accountlist',
	id: 'accountlist',
	fullscreen: true,
	
	config:{
		navigationBar: false,
		items:[
		{
			title: 'Accounts',
			xtype: 'list',
			store: 'Accountstore',
			itemTpl: '<div>{account_no}</div>{accountname}',
                 }
                 ]
            }

BOTH is not working for me. Any help will be appreciated. Thank you.

Have you looked at the request? Are the params there?

If extraParams contains vars, they will not submitted to server. With static content its fine. also json-proxy works. it took my hours to recognize that. I was believing my var is not initialize at right time, but i think it is a bug!

[mitchellsimoens]

As long as the variables have a value before the lines are eval'd by the browser it will be fine. For example, this will work:

var url       = 'someurl.com',
    userid    = 1234,
    accesskey = 'abcdef';
        
var accountstore = Ext.create('Ext.data.Store', {
    storeId : 'Accountstore',
    model   : 'accountmodel',

    proxy : {
        type        : 'jsonp',
        url         : 'php/vtiger_account.php',
        callbackKey : 'callback',
        extraParams : {
            url       : url,
            userid    : userid,
            accesskey : accesskey
        }
        reader : {
            type : 'json'
        },
    }
});

But if you have just the store and after the store is created you try and define or change the url, userid or accesskey variables then it will not update.

Yes, you`re right. I made the mistake to set a var same es a field of a singleton (Ext.Class).

// i use a singleton to store global vars, e.g. login data, urls, timeouts. how to make sure, singleton is instantiated before store will use them? i think at app load, singleton will be instantiated. Should i manually load the store and before i set extraParams? sorry for hijacking
