Im trying to insert a simple handlebars, like this, but there's so little support and the guide in the official page is so sad that I couldnt accomplish this.
<head>
<!--HANDLEBAR-->
<script type="text/x-handlebars" data-template-name="say-hello">
Hello, <b>{{name}}</b>
</script>
<!--VIEW-->
<script>
var view = Ember.View.create({
templateName: 'say-hello',
name: "Bob",
});
view.appendTo('#templateHere'); //here I try to append the view
</script>
In firebug I get the error: unable to find the template "say-hello"...........but I dont know why doesnt find it
Finally I accomplished, I write the solutions here because I think that ember need more documentation and it's worth because is very interesting (and powerful):
The problem was that I create an object of my view before defining it. The right code is this:
....
<!--HANDLEBAR-->
<script type="text/x-handlebars" data-template-name="say-hello">
Hello, <b>{{name}}</b>
</script>
<!--VIEW-->
<script>
App = Ember.Application.create();
//DEFINE VIEW
App.Myview = Ember.View.extend({
templateName: 'say-hello',
name: "Bob",
});
//CREATE VIEW>
App.myview=App.Myview.create();
console.log(App.myview.get('name'));//only for debug
//APPEND VIEW
$(function() {
App.myview.append('#templateHere');
});
</script>
</head>
<body>
<div id="templateHere"></div>
</body>
</html>

Firstly my answer is not the full solution, but there are some simple SyntaxErrors in your example. Thats why it's not runable for me at all.
You are opening click( but didn't close it, for better clearance i reformatted your code and added the closing bracket.
A function normally get's called with brackets, so it should be Voices();
This is not necessary for every Browser, but normally an ending line in JavaScript get's an ;
$('#talks').click(
function(){
console.log('hi');
var talk= new p5.Speech();
talk.onLoad=Voices();
function Voices(){
talk.listVoices();
talk.setVoice('Google UK English Male');
}
talk.speak("What's up");
}
)
With that changes i get an console output like this:
VM43:3: hi
p5.speech.js:136 p5.Speech: voices not loaded yet!
p5.speech.js:89 p5.Speech: voices loaded!
I don't know how to solve the following: I'd like to let my Model generate real javascript dynamically based on some model logic.
This final piece of javascript code then should be added inside the $(document).ready { } part of my html page.
The thing is: If I use inline="javascript", the code gets quoted as my getter is a String (that is how it is mentioned in the Thymeleaf doc but it's not what I need ;-)
If I use inline="text" in is not quoted but all quotes are escaped instead ;-) - also nice but unusable 8)
If I try inline="none" nothing happens.
Here are the examples
My model getter created the following Javascript code.
PageHelper class
public String documentReady() {
// do some database operations to get the numbers 8,5,3,2
return "PhotoGallery.load(8,5,3,2).loadTheme(name='basic')";
}
So if I now try inline="javascript"
<script th:inline="javascript">
/*<![CDATA[*/
jQuery().ready(function(){
/*[[${pageHelper.documentReady}]]*/
});
/*]]>*/
</script>
it will be rendered to
<script>
/*<![CDATA[*/
jQuery().ready(function(){
'PhotoGallery.load(8,5,3,2).loadTheme(name=\'basic\')'
});
/*]]>*/
</script>
Which doesn't help as it is a String literal, nothing more (this is how Thymeleaf deals with it).
So if I try inline="text" instead
<script>
/*<![CDATA[*/
jQuery().ready(function(){
PhotoGallery.load(8,5,3,2).loadTheme(name='basic')
});
/*]]>*/
</script>
Which escapes the quotes.
inline="none" I do not really understand, as it does nothing
<script>
/*<![CDATA[*/
jQuery().ready(function(){
[[${pageHelper.documentReady}]]
});
/*]]>*/
</script>
To be honest I have no idea how to solve this issue and hopefully anybody out there knows how to deal with this.
Many thanks in advance
Cheers

I would change the approach.
Thymeleaf easily allows you to add model variables in your templates to be used in Javascript. In my implementations, I usually put those variables somewhere before the closing header tag; to ensure they're on the page once the JS loads.
I let the template decide what exactly to load, of course. If you're displaying a gallery, then render it as you would and use data attributes to define the gallery that relates to some JS code. Then write yourself a nice jQuery plugin to handle your gallery.
A relatively basic example:
Default Layout Decorator: layout/default.html
<!doctype html>
<html xmlns:layout="http://www.thymeleaf.org" xmlns:th="http://www.thymeleaf.org">
<head>
<title>My Example App</title>
<object th:remove="tag" th:include="fragments/scripts :: header" />
</head>
<body>
<div layout:fragment="content"></div>
<div th:remove="tag" th:replace="fragments/scripts :: footer"></div>
<div th:remove="tag" layout:fragment="footer-scripts"></div>
</body>
</html>
The thing to notice here is the inclusion of the generic footer scripts and then a layout:fragment div defined. This layout div is what we're going to use to include our jQuery plugin needed for the gallery.
File with general scripts: fragments/scripts.html
<div th:fragment="header" xmlns:th="http://www.thymeleaf.org">
<script type="text/javascript" th:inline="javascript">
/*<![CDATA[*/
var MY_APP = {
contextPath: /*[[#{/}]]*/,
defaultTheme: /*[[${theme == null} ? null : ${theme}]]*/,
gallery: {
theme: /*[[${gallery == null} ? null : ${gallery.theme}]]*/,
images: /*[[${gallery == null} ? null : ${gallery.images}]]*/,
names: /*[[${gallery == null} ? null : ${gallery.names}]]*/
}
};
/*]]>*/
</script>
</div>
<div th:fragment="footer" xmlns:th="http://www.thymeleaf.org">
<script type="text/javascript" src="/js/jquery.js"></script>
<script type="text/javascript" src="/js/my_app.js"></script>
</div>
In the scripts file, there are 2 fragments, which are included from the decorator. In the header fragment, a helpful context path is included for the JS layer, as well as a defaultTheme just for the hell of it. A gallery object is then defined and assigned from our model. The footer fragment loads the jQuery library and a main site JS file, again for purposes of this example.
A page with a lazy-loaded gallery: products.html
<html layout:decorator="layout/default" xmlns:layout="http://www.thymeleaf.org/" xmlns:th="http://www.thymeleaf.org">
<head>
<title>Products Landing Page</title>
</head>
<body>
<div layout:fragment="content">
<h1>Products</h1>
<div data-gallery="lazyload"></div>
</div>
<div th:remove="tag" layout:fragment="footer-scripts">
<script type="text/javascript" src="/js/my_gallery.js"></script>
</div>
</body>
</html>
Our products page doesn't have much on it. Using the default decorator, this page overrides the page title in the head. Our content fragment includes a title in an h1 tag and an empty div with a data-gallery attribute. This attribute is what we'll use in our jQuery plugin to initialize the gallery.
The value is set to lazyload, so our plugin knows that we need to find the image IDs in some variable set somewhere. This could have easily been empty if the only thing our plugin supports is a lazyloaded gallery.
So the layout loads some default scripts and with cleverly placed layout:fragments, you allow certain sections of the site to load libraries independent of the rest.
Here's a basic Spring controller example, to work with our app: MyController.java
#Controller
public class MyController {
#RequestMapping("/products")
public String products(Model model) {
class Gallery {
public String theme;
public int[] images;
public String[] names;
public Gallery() {
this.theme = "basic";
this.images = new int[] {8,5,3,2};
this.names = new String[] {"Hey", "\"there's\"", "foo", "bar"};
}
}
model.addAttribute("gallery", new Gallery());
return "products";
}
}
The Gallery class was tossed inline in the products method, to simplify our example here. This could easily be a service or repository of some type that returns an array of identifiers, or whatever you need.
The jQuery plugin that we created, could look something like so: my_gallery.js
(function($) {
var MyGallery = function(element) {
this.$el = $(element);
this.type = this.$el.data('gallery');
if (this.type == 'lazyload') {
this.initLazyLoadedGallery();
}
};
MyGallery.prototype.initLazyLoadedGallery = function() {
// do some gallery loading magic here
// check the variables we loaded in our header
if (MY_APP.gallery.images.length) {
// we have images... sweet! let's fetch them and then do something cool.
PhotoGallery.load(MY_APP.gallery.images).loadTheme({
name: MY_APP.gallery.theme
});
// or if load() requires separate params
var imgs = MY_APP.gallery.images;
PhotoGallery.load(imgs[0],imgs[1],imgs[2],imgs[3]).loadTheme({
name: MY_APP.gallery.theme
});
}
};
// the plugin definition
$.fn.myGallery = function() {
return this.each(function() {
if (!$.data(this, 'myGallery')) {
$.data(this, 'myGallery', new MyGallery(this));
}
});
};
// initialize our gallery on all elements that have that data-gallery attribute
$('[data-gallery]').myGallery();
}(jQuery));
The final rendering of the products page would look like so:
<!doctype html>
<html>
<head>
<title>Products Landing Page</title>
<script type="text/javascript">
/*<![CDATA[*/
var MY_APP = {
contextPath: '/',
defaultTheme: null,
gallery: {
theme: 'basic',
images: [8,5,3,2],
names: ['Hey','\"there\'s\"','foo','bar']
}
};
/*]]>*/
</script>
</head>
<body>
<div>
<h1>Products</h1>
<div data-gallery="lazyload"></div>
</div>
<script type="text/javascript" src="/js/jquery.js"></script>
<script type="text/javascript" src="/js/my_app.js"></script>
<script type="text/javascript" src="/js/my_gallery.js"></script>
</body>
</html>
As you can see, Thymeleaf does a pretty good job of translating your model to valid JS and actually adds the quotes where needed and escapes them as well. Once the page finishes rendering, with the jQuery plugin at the end of the file, everything needed to initialize the gallery should be loaded and ready to go.
This is not a perfect example, but I think it's a pretty straight-forward design pattern for a web app.
instead of ${pageHelper.documentReady} use ${pageHelper.documentReady}
I want the cursor to be focused on the textbox when I load the page. I tried by adding autofocus="" but I couldn't find any difference in that.
Any help would be greatly appreciated!
#Html.TextBoxFor(
m => m.UserName,
"#xyz.com",
new { #class = "form-control input-lg", #id = "username"})
If you are ok with jquery, you can try using
<script type="text/javascript">
$(function () {
$("#username").focus();
});
</script>
You could use plain java script like this:
<script type="text/javascript">
document.getElementById("username").focus();
</script>
The autofocus attribute isn't implemented in all browsers. It's a good subset of browsers with most newer browsers having it, but not all. It is likely you were using a browser that does not support the autofocus attribute. Dive into HTML 5 has a good listing of the browser support.
<script type="text/javascript">
$(document).ready(function(){
$("#username").focus();
});
}); </script>
I am new in jquery I desperately need some help in running this code.I am trying to create a fade in-fade out image banner with 4 images within div tag, with the help of a function fadingbanner() which calls itself recursively and is initiated by a settimeout function.But for some reason its not working.Please help....
<HTML>
<HEAD>
<script type= "text/javascript" src="C:\Documents and Settings\A\Desktop\jquery-1.9.1.js"></script>

<img src = "C:\Documents and Settings\A\Desktop\web_files\temp3.jpg" id = "i3">
<img src = "C:\Documents and Settings\A\Desktop\web_files\temp4.jpg" id = "i4">
</div>
function fadingbanner()
{
$(document).ready(function(){
$("#i1").fadeOut(2000,function(){
$("#i2").fadeIn(2000,function(){
$("#i2").fadeOut(2000,function(){
$("#i3").fadeIn(2000,function(){
$("#i3").fadeout(2000,function(){
$("#i4").fadeIn(2000,function(){
$("#i4").fadeout(2000,function(){
fadingbanner();
});
});
});
});
});

});
}
</SCRIPT>

<BODY>
<IMG NAME = "bannerimage" src = "C:\Documents and Settings\A\Desktop\web_files\temp1.jpg" height = "200" width = "600" onload = "settimeout("fadingbanner()",1000)">
</BODY>
</HTML>
Take out the function and it should work ok. It is only defining a function and never running it. If it did run it, all it would do is schedule the code to run when the document finishes loading.
You also want to hide all but the first picture at the start.
So it should be like:
$(document).ready(function(){
$("#i2, #i3, #i4").hide();
$("#i1").fadeOut(2000,function(){
... all that other stuff
});
});
Here is a fiddle showing it: http://jsfiddle.net/ePBkX/1/
I borrowed the pictures there from the fiddle attached to this, which you might want to read: jQuery fade out then fade in

<script type="text/javascript" src="http://maps.googleapis.com/maps/api/js?libraries=places&sensor=true"></script>
<script src="Scripts/jquery-1.4.1.min.js" type="text/javascript"></script>
<script type="text/javascript">
$(function () {
var input = document.getElementById('location');
var options = {
types: ["locality"]
};
autocomplete = new google.maps.places.Autocomplete(input, options);
});
</script>
</head>
<body>
<div>Location: <input type="text" id="location" style="width:400px;" /></div>
</body>
</html>
There is my code to generate my autocomplete location text input. Google's list of supported types (http://code.google.com/apis/maps/documentation/places/supported_types.html) shows "locality" as being the type to use when I do not wish for everything to come back in the result(businesses, etc). I am getting no results.
Basically, what I would like to achieve is to search for a city (IE: Toronto) And only see results like: "Toronto, ON, Canada". Perhaps I am confused on how I implement this API.
Thank you very much for your replies!
I think the option you are looking for according to the docs is "geocode" ( http://code.google.com/apis/maps/documentation/javascript/reference.html#AutocompleteOptions ):
var options = {
types: ["geocode"]
};
you can also use the country restriction
example:
<script type="text/javascript" src="http://maps.googleapis.com/maps/api/js?libraries=places&sensor=false"></script>
<script type="text/javascript">
function initialize()
{
var input = document.getElementById('searchTextField');
var options = {
types: ['(cities)'],
componentRestrictions: {country: "ca"}
};
autocomplete = new google.maps.places.Autocomplete(input, options);
}
google.maps.event.addDomListener(window, 'load', initialize);
</script>
<input id="searchTextField" type="text" size="50" placeholder="Anything you want!">
now you can easily add a dropdown with a selection of cities and re-filter the cities, when onchange of the dropdown occurs :)
Try, check out the jsfiddle:
var options = {
types: ['geocode']
};
types, which can be either establishment or geocode, representing
businesses or addresses, respectively. If types is not specified, both
types are returned.
If the user types Tor in the input field and the output you want is Toronto, ON, Canada then you should use types=(regions), with the brackets.
I don't know if the option was present when the question was asked, but it is available now.
Sample Request:
https://maps.googleapis.com/maps/api/place/autocomplete/json?input=Tor&key=<YOUR_API_KEY_HERE>&types=(regions)
You can use like this
types: ['geocode' || 'establishment' || 'address']
