I have handlebars and I want them to be rendered conditionally.
F.e pseudo code:
if(condition)
{
<script id="template-1" type="text/x-handlebars-template">
...................
</script>
<script id="template-2" type="text/x-handlebars-template">
...............
</script>
}
else
{
if(condition2)
{
<script id="template-1" type="text/x-handlebars-template">
................
</script>
}
else
{
<script id="template-2" type="text/x-handlebars-template">
..........
</script>
}
}
so I do not want to repeat template1 and template2 handlebars in cshtml. How can I achieve this?

I'm trying to add a script to my view head part. Problem is when I load view I'm getting a console error "Uncaught ReferenceError: myfunction is not defined". As I understand my script wasn't loaded. I just started working with .NET.ASP MVC.
Here is part of my view.cshtml
#model dynamic
#{
var rUser = ViewBag.User as MyAplication.Model.User;
}
#section head {
#if (!rUser.IsPremiumMember)
{
<script type="text/javascript">
myfunction
</script>
<script type="text/javascript" async="async" data-cfasync="false" src="https://script.js"></script>
<script type="text/javascript" async="async" data-cfasync="false" src="https://otherscript.js"></script>
}
}
I used the following code to implement autocomplete textbox in MVC. But when I debug the project it shows a pair of angle brackets in the browser. pls examine my code.
controller:
public ActionResult Autocomplete(string searchstr)
{
var tenders = db.farmas.Where(t => t.Itemname.ToLower()
.Contains(searchstr.ToLower())).Take(10)
.OrderBy(t => t.Itemname)
.Select(t => new { label = t.Itemname });
return Json(tenders, JsonRequestBehavior.AllowGet);
}
view:
<!DOCTYPE html>
<html>
<head>
<h2>Autocomplete</h2>

Hey there, total javascript noob here. Just wondering, I've set up some buttons inside ul tags using jquery selectable, which change colour when I click on them. One problem though, how do I make one of them select on the load of the page?
Thanks!
edit: here's my code:
<link rel="stylesheet" href="style/style.css" media="screen,projection" type="text/css" />
<link href="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8/themes/base/jquery-ui.css" rel="stylesheet" type="text/css"/>

$('#target').load($('#single a:first').attr('href'));
});
function setLink(id){
$('#'+id+' a').click(function(e){
$('#target').load(
this.href,
function(){
setLink('target');
}
);
return false;
});
}

$document.getElementById('current1').click();
});

Simulate a click on document ready?
$(document).ready(function() {
$(".selectable .buttonSelector:first").click();
});
$('#myListItem').addClass('ui-selected');
I tried add click function on item, but seems that does not work correctly.
$(document).ready(function(){
$("#vibrateBtn").click(function() {
window.alert('test');
});
});
I tried also disable Ajax loading, with>
$(document).bind("mobileinit", function(){
ajaxEnabled:false;
});
But with same result.
Where can be problem please?
Thanks for any advice.
in jquery mobile document.ready() doesn't work and use .live to bind the click event instead of using the short hard .click().
There are other event like pagebeforecreate, pagecreate. check the jquery demo for the list of event.
$(document).live('pageshow',function(){
$("#vibrateBtn").live('click',function() {
window.alert('test');
});
});
Please try this code
<html>
<head>
<link rel="stylesheet" href="http://code.jquery.com/mobile/1.2.0/jquery.mobile-1.2.0.min.css" />
<script src="http://code.jquery.com/jquery-1.8.2.min.js"></script>
<script src="http://code.jquery.com/mobile/1.2.0/jquery.mobile-1.2.0.min.js"></script>
<script language="javascript">
$(function() {
$('#theButton').on('tap click',function(event, ui) {
alert('The Button has been clicked');
});
});
</script>
</head>
<body>
<div data-role="page">
<div data-role="content">
<input type="button" id="theButton" name="theButton" value="The Button">
</div>
</div>
</body>

I am developing some ajax stuff on asp.net mvc framework beta.
but,I got exception as following.
Anyone has problem like me?
Sys.ArgumentUndefinedException: Value cannot be undefined.
and my source code is like this.
<asp:Content ID="indexContent" ContentPlaceHolderID="MainContent" runat="server">
<script src="../../Scripts/jquery-1.2.6.js" type="text/javascript"></script>
<script src="../../Scripts/MicrosoftAjax.debug.js" type="text/javascript"></script>
<script src="../../Scripts/MicrosoftMvcAjax.debug.js" type="text/javascript"></script>
<script type="text/javascript">
var myView;
$(pageLoad);
function pageLoad() {
myView = $create(Sys.UI.DataView, {}, {}, {}, $get("ajaxResult"));
$("#callAjaxButton").click(callActionMethod);
}
function callActionMethod() {
$.getJSON("/Home/GetCategories", bindData);
}
function bindData(data) {
myView.set_data(data);
}
</script>
<input type="button" id="callAjaxButton" value="ajaxCall" />
<div id="ajaxResult"></div>
</asp:Content>
From the snippet you provided there are a couple of things to consider:
You are missing a script reference to the Microsoft ASP.NET 2.0 AJAX Templates for Visual Studio 2008.
You are using the jquery's document.ready function (raised whenever the DOM is ready to be traversed and manipulated) instead of the System.Application.init event (raised after all scripts have been loaded but before objects are created).
Can you try this to see if it works for you:
<script src="../../Scripts/jquery-1.2.6.js" type="text/javascript"></script>
<script src="../../Scripts/MicrosoftAjax.debug.js" type="text/javascript"></script>
<script src="../../Scripts/MicrosoftMvcAjax.debug.js" type="text/javascript"></script>
<script src="../../Scripts/MicrosoftAjaxTemplates.debug.js" type="text/javascript"></script>
<script type="text/javascript">
var myView;
Sys.Application.add_init(pageLoad);
function pageLoad() {
myView = $create(Sys.UI.DataView, {}, {}, {}, $get("ajaxResult"));
$("#callAjaxButton").click(callActionMethod);
}
function callActionMethod() {
$.getJSON("/Home/GetCategories", bindData);
}
function bindData(data) {
myView.set_data(data);
}
</script>
<input type="button" id="callAjaxButton" value="ajaxCall" />
<div id="ajaxResult"></div>
