I have searched the forum, and google for this topic. Most of the articles are talking about using JSON to call the controller/action on the server and do ajax effect on the result.
I am trying to use some very basic JQuery features, like the JQuery UI/Tabs, and JQuery UI/Block for a dialog window. I cannot get these simple samples to work in my MVC project. Any ideas how I should modify these samples? I only need these basic feature now and I can go from here.
Thanks!
Actually I just got it working. The problem is that I need to modify the path to an absolute path to the view page because the relative path doesn't work with the MVC routes {controller}/{action}/{id}.
Thanks!
For info, re the relative path issue - I discussed this here (the same concept applies to any page, not just master pages). The approach I used is like so:
1: declare an extension method for adding scripts:
public static string Script(this HtmlHelper html, string path)
{
var filePath = VirtualPathUtility.ToAbsolute(path);
return "<script type=\"text/javascript\" src=\"" + filePath + "\"></script>";
}
2: when needed (for example in the <head>...</head>) use this method:
<%=Html.Script("~/Scripts/jquery-1.2.6.js")%>
The advantage of this is that it will work even if the web app is hosted in a virtual directory (i.e. you can't use "/Scripts" because you aren't necessarily at the site root) - yet it is a lot clearer (and less messy) than the full script with munged src, i.e.
<script ... src="<%=Url.Foo(...)%>"></script>
I just implemented the jquery autocomplete textbox in one of my asp.net project. I only had to import the js file and drop some code into my aspx page. Could you be more detailled about what sample you are trying to run?
This is quick response!!
I am trying to run this "Simple Tabs" on this page:
http://stilbuero.de/jquery/tabs/
I think it is the same with this one: http://docs.jquery.com/UI/Tabs
I just copied and pasted the whole thing into my MVC view page, with corrected path to the jquery.js and .css files, but the content in the tabs all show up together (two of them are supposed to be hidden). My understanding is that this simple jquery plugin just show and hide content.
I had the exact same problem with the jquery thickbox plugin, that the item marked as "hidden" (the dialog box) will always show up in my MVC view page.
I can understand some of the MVC+Jquery+json articles, but I don't understand why the hide/show doesn't work.
Thanks!
I just made a walkthrough on how to do this:

This view suppose to show a list of hyperlinks, each pointing to an external URL. The goal is for the user to click one of these links and have their browser open a new tab with the selected URL.
Currently I have the following markup:
#Html.ActionLink("SomeSite", "http://subdomain.mydomain.com/SomeSite")
This markup produces:
http://localhost:58980/AccessInstance/http%3a/subdomain.mydomain.com/SomeSite
instead of :
http://subdomain.mydomain.com/SomeSite
What can I change in my markup to make this work as I expect?
You don't need to use #Html.ActionLink for that. Just use a plain A tag:
SomeSite
Html.ActionLink is specifically for generating links to actions defined in MVC controllers, in the same app. Since you're linking to an absolute URL, you don't need any of the functionality that Html.ActionLink provides.
Two ways :
1. update the database column with full link:
eg SQL:
update ProductTable set ProductLink='http://www.example.com/Product/Mobiles' where ID=123
In asp mvc view
View
2. Hardcode the http part and list from model
View
Hope helps someone.
While a ViewBag is overused and not the best choice most of the time this is something that I had done when inheriting someone else's mvc app to do a quick fix for a URL that I needed to redirect to with a specific dynamically changing querystring parameter
<a target="_parent" href="http://localhost:56332/services/#ViewBag.factory">View Service</a>
Using .NET Core 6
This seems to be the most correct answer:
Link
This will generate the following result:
As you can see at the bottom left corner of the window before clicking the link, the URL address was rendered as it is (NOTE: The cursor was recorded out of place for some reason, that's a ShareX problem, ignore it).
Than link will be directly saved as a nvarchar(750) type (probably any character like type will do the work). No changes to the original link were made before saving it or on reading:
You need to take into account your RouteConfiguration.
routes.MapRoute(
name: "Default",
url: "{controller}/{action}"
because you are specifying the action link as the entire link that you want to redirect.
I would recommend that you use the #rossipedia answer because you can make tricky things like putting a span inside the link
Here to display link that are clickable in index page
<td>
#Html.ActionLink(item.FileName, "../Uploads/Catalogue/"+item.FileName)
</td>
I have asp.net mvc project with knockout.js so my index page is getting really huge because of lots of javascript functionality.
I'd love to move js code into a separate file but it does not allow me to apply it to the most of the code because if I have something like
$.ajax({
url: "#Html.Raw(#Url.Action("Load"))",
Then it pops up a error if I move this part of the code into another file.
Please advise how can I resolve this issue?
Javascript files are not parsed by ASP.net, so the variables you have of #Html.Raw and #Url.Action("Load") will never be processed.
As #James Lai noted, server side code isn't parsed as such by ASP.Net. See this post for a workaround, or you can pick and choose which scripts can still stay on the page (with server-side code) instead of the "everything" - your choice as to which approach meets your requirements.
Javascript files are not parsed by ASP.NET MVC, thus #Html.Raw(#Url.Action("Load")) will not work in javascript file.
Heres workaround
Instead declare a variable in view.cshtml. In script section as
<script type="text/javascript">
var actionUrl = '#Url.Action("Load", "Controller")';
</script>
And use actionUrl in javascript file.
Let's say I have 2 MVC web projects (web1 and web2) and 1 project containing shared views (common) (using the razorgenerator of David Ebbo)
web1 and web2 both have a test.cshtml file. Several blocks of code in both test.cshtml files are exactly the same.
I'm trying to find out if it's possible to share a declarative helper (#helper) between several cshtml files which are in DIFFERENT projects. So putting a cshtml file in my App_Code does not help (I would need to have 1 in each web project, which is obviously not what I want).
I know I could create a bunch of shared partial views in my 'common' project, but it seems kinda overhead to create 20 cshtml files that each contains a very small portion of html.
I know I can create a standard helper method (static string GenerateAPieceOfHtml(this HtmlHelper helper, ....)), but there I loose the ease of writing html as you can do it in a cshtml file.
For a short while I thought I bumped into an answer that would allow me to do it. But as I wrote in a comment, that code did not compile for me.
I hope my question is clear :)
[Update]
As csharpsi asks in a comment.. I did try out the code from the other post, but it did not spit out any HTML for me. Since I started to think that that answer should probably do the trick since it has 13 upvotes, I decided to give it a second try..
Again I didn't get any output, but then I tried it a little bit different.. and success!
I was trying this (which doesn't spit out any html on the page):
#{ new Test().DoSomething(Model); }
This is the version that DOES WORK:
#{
var html = new Test().DoSomething(Model);
#html
}
Other version that works:
#(new Test().DoSomething(Model))
What should I do with this question? Delete it? Write an answer myself?
Why are you trying to use razor helper for this anyway ? Razor helpers are one-particular-viewengine hack, your application shouldnt rely on them on many places (even amongst different websites). In this case, be sure to use standard MVC way - HTML helper. These you can easily share between websites, for example you can make your own class library full of them.
We have an editor template that contains approx 40 lines of jquery. I tried dropping this script into a <asp:Content> block to keep all of the javascript in one location within the page. However, I get the following error message content controls have to be top-level controls in a content page.
Is there any way to get this working so we don't have script dotted around our final output pages or could someone recommend the best practice for storing javascript used within ASP.NET MVC templates? At the moment I'm thinking of pulling the code into a separate file and referencing it within the master page but this means it gets pulled into every page which isn't really ideal.
Thanks in advance.
It would be easier for later maintenance, if you keep the javascript into a separate file and reference it where ever it is needed. Also, if you feel that placing all script into a single file will increase unnecessary loading of scripts, where not needed, then break the scripts into separate files based on functionality/modules in which it is useful etc. strategy and then reference them instead.
Also, it was said that always, keep/reference the scripts at the bottom of the page so that page loading will be faster.
as siva says, bottom of the page is the 'ideal'. however, as for seperate files. this is only going to be practical as long as you don't reference asp.net elements from the page - ie:
<asp:Content ContentPlaceHolderID="jsCode" ID="jsCode1" runat="server">
<script type="text/javascript">
$(document).ready(function() {
getPoundsData();
});
function getPoundsData() {
var id = $("#ID").val();
var URL = '<%=Url.Action("GetPounds", "FundShareholder")%>';
var params = { id: id };
if (id != null)
SendAjaxCache("#" + $("#ShareholderID option:selected").text() + " RSP#", URL, params, null, ListDataShareholderPounds);
}
function ListDataShareholderPounds(data) {
if (data.length != 0) {
$('#shareholderPounds').html("");
$('#shareholderPounds').show();
$('#shareholderPounds').html(data);
}
};
</script>
</asp:Content>
notice the:
var URL = '<%=Url.Action("GetPounds", "FundShareholder")%>';
part in the js. what 'we' do is to add a content section to the master page at the very bottom to hold our js stuff. however, this only works inside the ViewPage (aspx) object. the ascx pages are 'ignorant' of any master page content sections.
We are currently working on systemizing the process whereby we save 'partial' js files with asp.net references inside them and then inject them into the page-flow via a filterattribute. we're at an early stage with this but the nice thing about this approach is that the partial js is treated as a file and is therefore cached for future visits to that page.
anyway, that's our current approach, would be interested to discover if peeps are using any similar mechanisms to inject js that contains asp.net object references.
cheers...
[edit] - here's a heads up on the approach i'm talking about (this wasn't our original inspiration, but is quite similar, tho is webforms, rather than mvc) - http://www.west-wind.com/WebLog/posts/252178.aspx or this one which IS mvc: http://poundingcode.blogspot.com/2009/12/injecting-javasript-into-aspnetmvc-with.html.
Finally found the article that inspired our 'search' in this: ASP.NET MVC routing and paths is js files plus http://codepaste.net/p2s3po
How to add FCKEditor in MVC application?
How to show database value comes in model, in FCKEditor?
That CodeProject website isn't ideal. It asks you to do alot of unneccessary code. All you really need to do is include the correct javascript file:
Then, in the page, render the FCKEditor, given any number of different ways. I prefer to replace a text area:
window.onload = function()
{
var oFCKeditor = new FCKeditor( 'content' ) ;
oFCKeditor.ReplaceTextarea() ;
}
At that point, the editor should load just fine. You will probably need to edit the fckeditor configuration files to get the standardized behavior you want. At this point, however, everything should just work. Your FCKEditor instance will behave just like another form field, and you can treat it as such when you get values from it on the server side.
It's very easy to create the server side api's for it to use as well. I created an fckeditor control, and you just need to implement GetFolders, GetFoldersAndFiles, and GetFiles. Those only take a few lines and give you nearly all the functionality you need.
I think it's easier to integrate / customize fckeditor using MVC than it is on Classic ASP.NET.
