I got a jquery reference in my _Layout.cshtml . It does not look like this is working in my Index.cshtml page though: the /Home/GetSquareRoot is not hit? (it works when I uncomment the jquery reference in the index.cshtml though)
ViewStart.cshtml
#{
Layout = "~/Views/Shared/_Layout.cshtml";
}
Index.cshtml
#{
ViewBag.Title = "Home Page";
}
<h2>#ViewBag.Message</h2>

It works when you have the jQuery reference commented out, because your _Layout.cshtml file has the reference as well (just stating the facts, I realise you probably know this).
This also means that you have your routing set up correctly and that there is nothing wrong with the URL '/Home/GetSquareRoot'
The code looks fine, the only unknown that I can see is that ../../Scripts/ actually goes to the same place as ~/Scripts/ (will depend on what the URL of your page looks like).
I would use Google Chrome to check for script errors on your page: go to your page, right click and 'inspect element' on the page, then check that you don't have any script errors (bottom right of the inspector will have a red circle if you do).
If you have script errors that could be stopping the AJAX call from running.
When referring to hard-coded content URLs in your application, it's always a good idea to use Url.Content.
So instead of this:
<script src="../../Scripts/jquery-1.5.1-vsdoc.js" type="text/javascript"></script>
use this:
<script src="#Url.Content("~/Scripts/jquery-1.5.1-vsdoc.js")" type="text/javascript"></script>
This way the correct URL to the jQuery script file will always be used, no matter what the URL of the page is.
Try out this one...
public JsonResult GetSquareRoot(long? number)
{
var square = Math.Sqrt(number);
return Json(new { result = square }, JsonRequestBehavior.AllowGet);
}

I have a file, which needs to have 90 modals with lots of long texts, because I need to create a modal when a link is clicked.
index.php

$(function(){
$('a').click(function(){
var link = $('#name').html(); // I need sent this to my calculator file
$.ajax({

success : function (a){

}
});
});
});

I need this text for php script

resuilt.php
/* I used PHP becase i need more functions, this only a example how

{
return "<div class='modal fade' id='$modal_ID' tabindex='-1' role='dialog' aria-labelledby='myModalLabel' aria-hidden='true'>
<div class='modal-dialog'>

<button type='button' class='btn btn-primary'>Save changes</button>
</div>
</div>
</div>
</div>";
}
echo create_modal();
?>
The result is, I need to click on the link two times to show my modal. But it can't close or does anything.
Where did it go wrong? And is there any way to make my idea better?
you can add
success : function (a){
$('#result').html(a);
$('#myModal').modal('show');
}
just add $('#myModal').modal('show'); when ajax load your modal in #result
I don't think 90 modals is a good idea.
Try saving data maybe in a databas.
Assign your links different ids.
Use jquery to listen to click events
Get data from your server
Populate modal with values from the server.
Check this stack overflow link.
Let me know if you need help
I'm using JQuery Mobile with a form that changes server side. I need to reload the page so the most recent form is included on the page. The form also needs validation.
I'm able to get the validation to work once but once until a submit. The page successfully is refreshed and the form appears but the validation is gone and if I submit, a standard submit is done instead of a changePage.
The on pageinit seems to be firing every time. I've been pulling my hair out on this one. It seems like this should be so simple.
<?php //
session_start();
if (isset($_SESSION['mytest']))
$_SESSION['mytest']++;
else
$_SESSION['mytest'] = 1;
$s = $_SESSION['mytest'];
?>

$.mobile.changePage( "#testit", { transition: "slideup", changeHash: false, reloadPage: true, allowSamePageTransition: true });
}
$(document).on('pageinit', function(){ //
$("#myform").validate( {
rules: {
myname: "required"
}
,submitHandler: function(e) { submitme(e);}
});
});
</script>

The problem here is the 'pageinit' event, which runs just once per page (its also deprecated). You'd have to use the pagecontainershow event, which runs each time the page is shown. That should initialize the form validation again, making it work for each time its rendered. Note that I haven't tested that solution, yet.
In my index view I have several Ajax.ActionLinks displayed as shown in the code below. I am trying to render a partial view into DIV section when one of those links is clicked. Right now, it is rendering the partial as its own page. What am I doing incorrectly?
View
<script src="#Url.Content("~/Scripts/jquery.unobtrusive-ajax.js")" type="text/javascript"></script>
...Other HTML
<article class="border c-two" style="background-image: url('/Content/images/Fancy.jpg')">
<div style="opacity: 0;" class="fdw-background">
<h4 style="color:#fff;">Fancy Schmancy</h4>
<p class="fdw-port">
#Ajax.ActionLink("Go Now", "GotoStore", "Simulation", new { id = 1 }, new AjaxOptions { UpdateTargetId = "Rest", InsertionMode = InsertionMode.InsertAfter, HttpMethod = "GET" })<span class="vg-icon">→</span>
</p>
</div>
</article>
...other HTML
<div id="Rest"></div>
Controller
public PartialViewResult GotoStore(int id)
{
Store store = db.Stores.Find(id);
return PartialView(store);
}
I was able to get it working. The problem was where I added in the script source.
This:
<script src="#Url.Content("~/Scripts/jquery.unobtrusive-ajax.js")" type="text/javascript"></script>
Needs to be placed inside your layout file towards the bottom like this:
#Scripts.Render("~/bundles/jquery")
<script src="#Url.Content("~/Scripts/jquery.unobtrusive-ajax.js")" type="text/javascript"></script>
#RenderSection("scripts", required: false)
I am new to MVC3 and I am trying to figure out how to use dotnet.highcharts. BTW I have read several post and none seem to help. I have tried to use the simple examples that accompanied the download from codeplex. I can't even get that to work even by copying and pasting. I hardly register with forums, I mainly just search for answers. I usually don't have much trouble and I feel bad that I have to ask a question like this, but I need help. All I want to do is to simply create a chart. I will post my code any help will be appreciated.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using DotNet.Highcharts.Options;
using DotNet.Highcharts.Helpers;
using DotNet.Highcharts.Enums;
using DotNet.Highcharts;
namespace MyProject.Controllers
{
public class HomeController : Controller
{
public ActionResult Index()
{
ViewBag.Message = "Welcome to ASP.NET MVC!";
return View();
}
public ActionResult About()
{
return View();
}
public ActionResult PartialChart()
{
Highcharts chart = new Highcharts("chart")
.InitChart(new Chart { DefaultSeriesType = ChartTypes.Bar })
.SetTitle(new Title { Text = "Stacked bar chart" })
.SetXAxis(new XAxis { Categories = new[] { "Apples", "Oranges", "Pears", "Grapes", "Bananas" } })
.SetYAxis(new YAxis
{
Min = 0,
Title = new YAxisTitle { Text = "Total fruit consumption" }
})
.SetTooltip(new Tooltip { Formatter = "function() { return ''+ this.series.name +': '+ this.y +''; }" })
.SetPlotOptions(new PlotOptions { Bar = new PlotOptionsBar { Stacking = Stackings.Normal } })
.SetSeries(new[]
{
new Series { Name = "John", Data = new Data(new object[] { 5, 3, 4, 7, 2 }) },
new Series { Name = "Jane", Data = new Data(new object[] { 2, 2, 3, 2, 1 }) },
new Series { Name = "Joe", Data = new Data(new object[] { 3, 4, 4, 2, 5 }) }
});
return PartialView(chart);
}
}
}
This is the partialview:
#model DotNet.Highcharts.Highcharts
#(Model)
This is the index page:

ViewBag.Title = "Home Page";
}

With the help of a friend I have the answer. Just in case someone out there still cares. The problem was the reference to the Highcharts scripts. The scripts were located differently than listed in the example and being completely oblivous I didn't notice.

I am trying out knockoutjs at the moment, with my fairly rudimentary knowledge of javascript. I have set up a basic ASP.NET MVC 3 app for this purpose. Here's the snippet I set up in the Home/Index.cshtml view:
#if(false)
{
<script src="../../Scripts/jquery-1.6.3.js" type="text/javascript"></script>
<script src="../../Scripts/knockout-1.3.0beta.debug.js" type="text/javascript"></script>
}
#{
ViewBag.Title = "Home Page";
}
<script type="text/javascript">
var entryDataViewModel = {
registration: ko.observable("Registration"),
registeredName: ko.observable("Name"),
entryClass: ko.observable("Junior")
};
ko.applyBindings(entryDataViewModel);
</script>
<h2>#ViewBag.Message</h2>
<p>
Registration: <span data-bind="text: registration"></span><br />
Name: <span data-bind="text: registeredName"></span><br />
Class: <span data-bind="text: entryClass"></span><br />

For some weird reason nothing is showing, not even the default values. If I debug through Firebug the ViewModel is showing the properties as being empty too. Have I missed something here?
Many thanks,
Dany.
ADDED: the content of the _Layout.cshtml - it's all stock standard stuff, except for the addition of knockout, and using jquery 1.6.3

The answer I voted above only worked when I tried it in a plain webpage - not when I tried it in my MVC view. As it turned out I put the script block in the wrong position. I moved it to the end of the view, after the page elements have been processed. The other option is to wrap it within $(document).ready() then you can put the script block containing ViewModel and call to ko.applyBindings() anywhere you want...
use $(document).load(function(){:
<script type='text/javascript'>
//<![CDATA[
$(document).load(function(){
var entryDataViewModel = {
registration: ko.observable("Registration"),
registeredName: ko.observable("Name"),
entryClass: ko.observable("Junior")
};
ko.applyBindings(entryDataViewModel);
});
//]]>
</script>
Have a look: http://jsfiddle.net/S8Rh5/ - it works just fine.
