I am currently working my way through David Sulc's excellent "Backbone.Marionette.js: A Gentle Introduction" and have come unstuck at modules. With the app as it currently stands I am trying to access an API in a module called 'contacts.js' from the index.html script but I get the following error when I try to run the app:
"Handler not found for 'contact: entities' "
I am able to hit the API directly from the console in Chrome and manually get the 'contact' information so I was thinking this was a loading sequence problem where the API might not be available by the time app.js loads, however the loading sequence is as follows:
<script type="text/javascript" src="assets/js/vendor/jquery-2.0.3.min.js"></script>
<script type="text/javascript" src="assets/js/vendor/json2.js"></script>
<script type="text/javascript" src="assets/js/vendor/underscore-min.js"></script>
<script type="text/javascript" src="assets/js/vendor/backbone-min.js"></script>
<script type="text/javascript" src="assets/js/vendor/backbone.marionette.min.js"></script>
then the local scripts as follows:
<script type="text/javascript" src="assets/js/app.js"></script>
<script type="text/javascript" src="assets/js/entities/contact.js"></script>
and a script tag below the last two script tags directly runs the following code:
<script type="text/javascript">
... some view code
ContactManager.on("initialize:after", function(){
var contacts = ContactManager.request("contact: entities");
... some more code
</script>
the line beginning var contacts = ..... is the one giving me the error. Any help appreciated
I am as certain as I can be that I have scripted this exactly as per the book.
You have a space in your event name:
<script type="text/javascript">
... some view code
ContactManager.on("initialize:after", function(){
// Remove the space in contact: entities -->
var contacts = ContactManager.request("contact: entities");
... some more code
</script>

i have a project which is written in MVC3,its a signalR,i got the code to edit some part but i see its gives an error,on the following part which says cant start a null refrence:
$.connection.hub.start().done(FUNCTION....)
meaninf the valu of hub is null,the fowlooing are the scripts which are loading:
<script src="#Url.Content("~/Scripts/jquery-1.7.2.min.js")" type="text/javascript"></script>
<script src="#Url.Content("~/Scripts/jquery.unobtrusive-ajax.min.js")" type="text/javascript"></script>
<script src="#Url.Content("~/Scripts/leitwind/dateExtension.min.js?ver=1")" type="text/javascript"></script>
<script src="#Url.Content("~/Scripts/knockout-3.0.0.js")" type="text/javascript"></script>
<script src="#Url.Content("~/Scripts/knockout.mapping-latest.js")" type="text/javascript"></script>
<script src="#Url.Content("~/Scripts/leitwind/knockoutAutoRefresh.min.js")" type="text/javascript"></script>
<script src="#Url.Content("~/Scripts/DataTables-1.9.2/media/js/jquery.dataTables.min.js")" type="text/javascript"></script>
<script src="#Url.Content("~/Scripts/jquery.signalR-0.5.2.min.js")" type="text/javascript"></script>
<script src="#Url.Content("~/signalr/hubs")"></script>
when i go to the developer option of the browser its showing the error on the last refrence,signalr/hubs which does not exist!im wondering why the project is running on the server but not on the local pc even thought i have the same scripts and anything has been changed,after one day of investigation i thought maybe i should give the address of the server instead of signalr/hubs,with this work around i that error is not threwing any more but i have the following issue,all in all i dont have any idea where i should look
is there something wrong with the url format?
i need to set the address manually in my code in order to get data from the server,for the follwoing part:
$.connection.hub.url ='https://myserver.com/file/signalr/';
$.connection.hub.start().done()
This is the script in my index.html
<script type="text/javascript" src="http://api.map.baidu.com/api v=2.0&ak=eBGR7XzaPhB5UbYARl3E7ksdkMdgrCw7"></script>
and I try to access a object --"BMap" from the script in my JS page which look like this:
var map = new BMap.Map("allmap"); // 创建Map实例
then I get error:"error! BMap is not defined"
what should I do?
I am guessing that you wanted to use BMap that is provided by baidu api. I changed the src that is actually pointing to the script and it seems to work. Note that you probably want to change the https to http when you are developing locally, as it may not work otherwise. See working example below (I had to use https because stackoverflow uses it by default).
If you have any other js module that uses BMap, make sure that it is called after the baidu api script is declared. S

I am trying to make wall script like google+ but i have one problem. Users can share pictures and videos I've created a base. However, the tab does not work currently. Reason ... <script type="text/javascript"> </ script> I think it is relevant. .... tags into the tags I add the script call. But by far misunderstood. but I could not. I'm giving you my code below.

Call javascript function This function for post cancel or submit
<script type="text/javascript">
$(function(){
$(".content").focus(function(){
$(this).animate({"height": "55px",}, "fast" );
$("#button_hide").slideDown("fast");
return false;
});
$("#cancel").click(function(){
$(".content").animate({"height": "30px",}, "fast" );
$("#button_hide").slideUp("fast");
return false;
});
});
</script>
and this javascript function is for Photo and video click open box also this function is not working now.
<script type="text/javascript">
$(document).ready(function(){
$(".oculto").hide();
$(".MO").click(function(){
var nodo = $(this).attr("href");
if ($(nodo).is(":visible")){
$(nodo).hide();
return false;
}else{
$(".oculto").hide();
$(nodo).fadeToggle( "slow" );
return false;
}

What is there in this file js/jquery.min2.js? If it is the jquery library, please remove it because you have a google cdn code in the same file. In addition, you are using a old version of jquery. Since 1.4 many things have changed in jQuery so, please use the latest version of jquery http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js
<script type="text/javascript"

I think that leads up the tab portions. Just like facebook. I understand that you have used bubble box. If you want three different areas. For example: status, video, link to share, create the base area. This will provide you more convenience.
You can write your php code easier.
Because sharing is currently part of three different courses you want to use a single form. But you can spend more time for it. However, creating three forms that will be easier if you make sharing.
Share your theme really nice congratulations. However troubling.
I've studied your own scripts. Bonding between the lines of the script too much. This is not true. Create a new js file and then type into the function you are using. Gators later use the following code:
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
<script type="text/javascript" src="js/jquery.oembed.js"></script>
<script type="text/javascript" src="js/yourscript.js"></script>
<script type="text/javascript" src="js/wall.js"></script>
In this way, your problems will disappear.
I have various JS libraries in my web application, which are loaded before my main JS file (main.js). One of these libraries is jshashtable, but when I try to create a new Hashtable object in main.js, Google Chrome and Firefox throw a ReferenceError, complaining that the variable does not exist.
Here is the <head> of the application:
<script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false"></script>
<script type="text/javascript" src="/static/jquery-1.4.4.min.js"></script>
<script type="text/javacsript" src="/static/jshashtable-2.1.js"></script>
<script type="text/javascript" src="/static/main.js"></script>
Here is the problem line in main.js:
posts = new Hashtable();
This line is inside a function called init which is called when the page has finished loading (using the jquery $(document).ready() function).
Any reason why Hashtable is not global? Google maps and jquery objects work with no such problem. The source of jshashtable can be seen on Google code.
Updated answer: The problem is that you've got a typo in the script tag:
<script type="text/javacsript" src="/static/jshashtable-2.1.js"></script>
<!-- ^^---- here (the letters are transposed) -->
I couldn't understand why you would be running into a problem and decided to actually copy-and-paste your script tags and replicate the structure exactly on my machine. And things stopped working and my world tilted 3° counter-clockwise until I finally stared at them long enough to see it.
Provided that the jshashtable code really is at /static/jshashtable-2.1.js and your server is serving it up correctly (double-check on Chrome's resources tab in the dev tools), I can't see any reason for that. Your scripts are in the right order, and jshashtable's docs show using a global Hashtable (and the code link you gave clearly shows it creating one).
Edit: I've just replicated that same structure (same scripts, same order, using jQuery(document).ready(function() { ... });) on my own server, and am not having that problem. I can create a Hashtable and use its functions.
My HTML:
<!DOCTYPE HTML>
<html>
<head>
<meta http-equiv="Content-type" content="text/html;charset=UTF-8">
<title>Test Page</title>
<script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false"></script>
<script type='text/javascript' src='jquery-1.4.4.js'></script>
<script type='text/javascript' src='jshashtable-2.1.js'></script>
<script type='text/javascript' src='main.js'></script>
</head>
<body>
</body>
</html>
My main.js:
jQuery(document).ready(function() {
try {
var ht = new Hashtable();
display("typeof ht = " + typeof ht);
display("ht.size() = " + ht.size());
}
catch (e) {
display("Exception: " + e);
}
function display(msg)
{
$("<p>").html(msg).appendTo(document.body);
}
});
Only difference is I'm not using a /static prefix, and I'm absolutely certain that makes no difference.
I Have usercontrol and i registered the following javascript method in code behind :
changeSelectedMenu(controlID);
the previous method is declared in JScript.js file so i registered it also .
but the following exception has been thrown :
Microsoft JScript runtime error: Object expected
The result page is :
<script src="~/Scripts/JQuery.js" type="text/javascript"></script>
<script src="~/Scripts/JScript.js" type="text/javascript"></script>
<script type="text/javascript">
//<![CDATA[
changeSelectedMenu('ctl00_ctl00_cntMain_procedureContentHolder_procedureMenu_appointmentsLink');//]]>
</script>
Is There anyone can help me to workaround this issue???
These aren't valid paths to your JavaScript:
<script src="~/Scripts/JQuery.js" type="text/javascript"></script>
<script src="~/Scripts/JScript.js" type="text/javascript"></script>
They need to be relative to the page or to the site root, for example:
<script src="/Scripts/JQuery.js" type="text/javascript"></script>
<script src="/Scripts/JScript.js" type="text/javascript"></script>
While ~/ works for resolving a path on the server-side, the browser doesn't know how to handle this. There are some other work-arounds in this question for making it work and still being app-relative.
