I have one problem that I can't understand. I've built many web applications under jQuery UI and with jQuery UI Autocomplete plugin
$("#autocompleteObchod").autocomplete({
source: function( request, response ) {
console.log('ok');
$.ajax({
url: "/eshops/default/search",
dataType: "json",
data: {
q: request.term
},
success: function( data ) {
response($.map(data, function (item) {
return {
label: item.name,
value: item.name,
id: item.uuid
};
}));
}
} );
},
minLength: 2,
select: function( event, ui ) {
$('#form-eshopId').val(ui.item.id);
}
} );
This code works on my localhost.
But when I deploy my application via Dokku (heroku), autocomplete wont work. Nothing. No event triggered, no error in console, no error with javascript. Nothing. Do you guys had similar problem ? I'm out of energy with this.
If you want to check my application check http://dev.dobravec.info/organizations/
And try search something at first inline search component.
You have something wrong with you jquery ui version.
First of all I tried to debug the code of your autocomplete code version. It never fires out because it never receives arguments from you. For script your call is like calling autocomplete({}) - does nothing.
What the hell I thought - somebody broke autocomplete?
I went to jquery ui cdn, copied autocomplete function and pasted it to console. And initialized autocomplete on your input again. And it works fine.
So I dont know why, I dont know who - but somebody has edited your version of autocomplete. Get the new one and enjoy.
Try for yourself:
First ctrl+v jquery ui autocomplete function to console:

I have just study jquery plugins and I find this code. I don't know much about javascript but I love that language, I try to learn more and more about that, please tell me more and more.
(function( factory ) {
if ( typeof define === "function" && define.amd ) {
define( ["jquery"], factory );
} else {
factory( jQuery );
}
}(function( $ ) {
$.extend($.fn, {
// http://jqueryvalidation.org/validate/
validate: function( options ) {
// if nothing is selected, return nothing; can't chain anyway
if ( !this.length ) {
if ( options && options.debug && window.console ) {
console.warn( "Nothing selected, can't validate, returning nothing." );
}
return;
}
// check if a validator for this form was already created
var validator = $.data( this[ 0 ], "validator" );
if ( validator ) {
return validator;
}
// Add novalidate tag if HTML5.
this.attr( "novalidate", "novalidate" );
validator = new $.validator( options, this[ 0 ] );
$.data( this[ 0 ], "validator", validator );
if ( validator.settings.onsubmit ) {
this.validateDelegate( ":submit", "click", function( event ) {
if ( validator.settings.submitHandler ) {
validator.submitButton = event.target;
}
// allow suppressing validation by adding a cancel class to the submit button
if ( $( event.target ).hasClass( "cancel" ) ) {
validator.cancelSubmit = true;
}
I am trying to define new attributes for a central controller (a backbone view actually) to make it more compartmentalised and structured. I try to separate the rendering I want to achieve in different cases by if statements, and implementing each case's rendering in those new attributes. But after insertion of the replacement code to achieve that and commenting of the code before it make my app not work.
What is the wrong thing I do.
Another way I can imagine to modularise it is to conditionally, again, to load different AMD/Require.js modeules I write, in a separate file/s, and load them. But How? Via require() inside the render:, or by new moduleName passed to the second argument to the define() below.
define([
'jquery',
'ratchet',
'underscore',
'backbone',
'models/login',
'text!templates/login.html',
'text!templates/app.html'
], function($, Ratchet, _, Backbone, LoginModel, LoginTmpl, AppTmpl){
var LoginView = Backbone.View.extend({
el: $("body"),
template_login: _.template(LoginTmpl),
template_app: _.template(AppTmpl),
initialize: function(){
this.model = new LoginModel;
this.listenTo(this.model, 'change', this.render);
this.render();
},
//Replacement code: two attributes:
render_login: function(){
this.$el.html(this.template_app( this.model.toJSON() ));
console.log(JSON.stringify(this.model) );
return this;
}
},
render_app: function(){
this.$("#content").html(this.template_login( this.model.toJSON() ));
console.log(JSON.stringify(this.model) );
return this;
},
render: function() {
/*
if (this.model.get('loginp') == true) {
this.$el.html(this.template_app( this.model.toJSON() ));
console.log(JSON.stringify(this.model) );
return this;
}
*/
/*
else {
this.$("#content").html(this.template_login( this.model.toJSON() ));
console.log(JSON.stringify(this.model) );
return this;
}
*/
//Replacement code:
if (this.model.get('loginp') == true) {
this.render_app;
} else {
this.render_login;
}
},
events: {
'click #loginbtn' : 'login',
'click #registerbtn' : 'register'
},
login: function(e){
e.preventDefault();
var formData = {};
$( 'input' ).each( function( i, el ) {
if( $(el).val() != '' ) {
if( el.id === 'username' ) {
formData[ el.id ] = $(el).val();
} else if( el.id === 'password' ) {
formData[ el.id ] = $(el).val();
}
}
console.log( i + ": " + $(el).val() );
console.log(JSON.stringify(formData) );
// Clear input field values
$( el ).val('');
});
this.model.save( formData );
}
});
return LoginView;
});
In render method your replacement code that call render_app and render_login, actualy did't execute them. Your forgot ()
if (this.model.get('loginp') == true) {
this.render_app();
} else {
this.render_login();
}
Summing up with the above answer, the forgotten brackets,
1-render_app and render_login to render_app() and render_login()
2-correcting the syntax error: the second bracket in render_login's function definition.
3-either interchanging render_app and render_login attribute names or the templates used in their anonym functions. they se each others'.
