I've been trying to isolate the mail feature from 2sxc mobius app to implement it on my own 2sxc projects, but so far I've only been successful on passing string, string dictionary. If I try to use the default string,object it gives several compiling not very specific errors.
Here's what I have working right now:
View:
<div>
<div>
<label for="testfield">Test field</label>
</div>
<div>
<input type="text" id="testfield" value="">
</div>
</div>
<div>
<button id="saveData" type="button" onclick="saveMailData()">Guardar dados</button>
</div>
<script type="text/javascript" src="/desktopmodules/tosic_sexycontent/js/2sxc.api.min.js" data-enableoptimizations="100"></script>
<script>
function saveMailData() {
var newItem = {
"user": "#Dnn.User.Username",
"testfield": $("#testfield").val()
};
$2sxc(#Dnn.Module.ModuleID).webApi.post("Form/ProcessForm", {}, newItem, true)
.success(function() {
alert("Success");
})
.error(function() {
alert("Error");
});
}

I would really like to avoid using dynamic to receive data (it's a nightmare for beginners), so can you help me to properly pass data as objects (string,object) from JS to controller and from controller to razor template?
If you try to use you'll somehow assume that the system will correctly convert these to number, date and so forth. This will usually not be reliable and cause a lot of side-effects. For example, a number from an input-field would be a string in the browser, so it would also arrive as a string in the server.
Dates would be worse: they would be treated as strings - and no automatic detection would turn them into dates, because the JSON format used by AJAX-calls has no standard for dates.
So basically both numbers and dates would give you no benefit if you tried an object approach (as it wouldn't automatically have the other type). So I'm not sure if there is any additional benefit. Is there another reason to do this?

I am facing a problem passing string to HTML page through javascript.
I have a window form,
A HTML file, where I have my Javascript and HTML code.
In the function in C# page, I have a string that I need to send to the HTML page through javascript. But I can not pass it. Please advise me.
Thanks
My C# method code below
private void Form1_Load(object sender, EventArgs e)
{
Assembly assembly = Assembly.GetExecutingAssembly();
StreamReader reader = new StreamReader(assembly.GetManifestResourceStream("ProjectName.Maps.html"));
webBrowser1.DocumentText = reader.ReadToEnd();
***//pass getDefaultMap() value (str) to the javascript in Maps.html page.***
}
private string getDefaultMap()
{
string str;
str = (#"Exec SP_Map_Display #Opt=1");
return str ;
}
My HTML page is below
<body>
<script>
$(document).ready(function () {
$("#btnSubmit").click(function () {
***// Get the data from C# code str***
}
</script>
<input type="button" name="btnSubmit" value="Submit" />
<div id="dvMap">
</div>
</body>
Assuming this is WinForms since there's a WebBrowser control, to call C# code from the HTML page JavaScript can be accomplished with this minimum example:
Simple HTML page added to the root of the project and Properties was setup to Copy to Output Directory: Copy if newer this will ensure there's a simple page for testing:
<!DOCTYPE html>
<html lang="en" xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta charset="utf-8" />
<title>WebForms WebBrowser Control Client</title>
</head>
<body>
<input type="button" onclick="getLocations()" value="Call C#" />
<script type="text/javascript">
function getLocations() {
var locations = window.external.SendLocations();
alert(locations);
}
</script>
</body>
</html>
The JS function getLocations will call C# method SendLocations, the important parts are the Form1 class annotations and setting webBrowser1.ObjectForScripting = this :
using System.Windows.Forms;
using System.Security.Permissions;
using System.IO;
[PermissionSet(SecurityAction.Demand, Name = "FullTrust")]
[System.Runtime.InteropServices.ComVisibleAttribute(true)]
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
webBrowser1.ObjectForScripting = this;
var path = Path.GetFullPath("Client.html");
var uri = new Uri(path);
webBrowser1.Navigate(uri);
}
public string SendLocations()
{
return "SF, LA, NY";
}
}
Clicking the HTML button Call C# will show a popup with the return value from C# method
I don't know how to use razor syntax in Javascript.
I want to make Html.ListBoxFor with items from my model. I used to use:
#Html.ListBoxFor(x => x.TagIdList, (MultiSelectList)ViewBag.Tags, new { #class = "chzn-select", data_placeholder = "Tags..." })
As you see I want also use chzn-select class, to have better layout.
For now, I just have this code above in HTML as plain text, but I want have there things from my model.
Any ideas?
There is my code in ASP.NET MVC:
#model Generator.Models.ExamModel
#{
ViewBag.Title = "Generate";
}
#section Scripts {
#Scripts.Render("~/bundles/jqueryval")
<script src="#Url.Content("~/Multiple_chosen/chosen.jquery.js")" type="text/javascript"></script>
<script src="#Url.Content("~/Scripts/ListOfTags.js")" type="text/javascript"></script>
<script >
$(".chzn-select").chosen();
</script>
}
<link href="#Url.Content("~/Multiple_chosen/chosen.css")" rel="stylesheet" type="text/css" />
<h1>#ViewBag.Title</h1>
<h2>#ViewBag.Message</h2>
#using (Html.BeginForm())
{
#Html.AntiForgeryToken()
#Html.ValidationSummary(true)
<fieldset>
<legend>Generate</legend>
<div class="editor-label">Numbers</div>
<div class="editor-field" id="NumberOfModels">
#Html.EditorFor(model => model.NumberOfQuestions)
</div>
<div class="editor-label">Tags</div>
<div id="itemsmodel"></div>
<br>
<p>
<input type="submit" value="Save" />
</p>
</fieldset>
}
And there is javascript file:
var models = document.getElementById("NumberOfQuestions");
var modelsTable = document.getElementById("itemsmodel");
models.addEventListener("change", drawModels, false);
function drawModels() {
var modelsNum = parseInt(models.value);
var curModels = modelsTable.childElementCount;
if (modelsNum > curModels) {
var delta = modelsNum - curModels;
for (var i = 0; i < delta; i++) {
var input = document.createElement("div");
input.className = "editor-field";
input.innerHTML = "#Html.ListBoxFor(x => x.TagIdList, (MultiSelectList)ViewBag.Tags, new { #class = \"chzn-select\", data_placeholder = \"Tags...\" })";
modelsTable.appendChild(input);
}
} else {
while (modelsTable.childElementCount > modelsNum) {
modelsTable.removeChild(modelsTable.lastChild);
}
}
}
drawModels();
My ViewModel: ExamModel.cs:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
namespace ExamGenerator.Models
{
public class ExaminationModel
{
public int Id { get; set; }
public string Name { get; set; }
public List<int> TagIdList { get; set; }
public int NumberOfQuestions { get; set; }
public string Content { get; set; }
}
}
My ActionResult Generate() in controller:
public ActionResult Generate()
{
ViewBag.Tags = new MultiSelectList(genKolEnt.TAGS, "Id", "Name", null);
return View();
}
While you can generate HTML in Javascript using Razor, if the Javascript is in an MVC view, I find that injecting into JS leads to maintenance problems. You ideally want all your JS in separate files to allow for bundling/caching and the ability to break-point the JS code (which is harder in the view).
Either inject only simple things into JS on the page, or inject elements instead.
You can inject your template Razor list into a dummy script block, so you can extract the html from it later. The type="text/template" means the browser will ignore it e.g.:
<script id="ListTemplate" type="text/template">
#Html.ListBoxFor(x => x.TagIdList, (MultiSelectList)ViewBag.Tags, new { #class = "chzn-select", data_placeholder = "Tags..." })
</script>
The view page now looks like this (left out the irrelevant parts):
#section styles{
<link href="#Url.Content("~/Multiple_chosen/chosen.css")" rel="stylesheet" type="text/css" />
}
<h1>#ViewBag.Title</h1>
<h2>#ViewBag.Message</h2>
<script id="ListTemplate" type="text/template">
#Html.ListBoxFor(x => x.TagIdList, (MultiSelectList)ViewBag.Tags, new { #class = "chzn-select", data_placeholder = "Tags..." })
</script>
#using (Html.BeginForm())
{
#Html.AntiForgeryToken()
#Html.ValidationSummary(true)
<fieldset>
<legend>Generate</legend>
<div class="editor-label">Numbers</div>
<div class="editor-field" id="NumberOfModels">
#Html.EditorFor(model => model.NumberOfQuestions)
</div>
<div class="editor-label">Tags</div>
<div id="itemsmodel"></div>
<br>
<p>
<input type="submit" value="Save" />
</p>
</fieldset>
}
Script now looks like this (jQuery version with JS as comments):
// ListOfTags.js file
// This is a shortcut DOM ready handler for $(document).ready(function(){ YOUR CODE HERE })
$(function () {
// Attach an event handler for the "change" event
$('#NumberOfQuestions').change(function () {
var $numberOfQuestions = $(this); // Convert current DOM element (the counter) to a jQuery element
var $modelsTable = $('#itemsmodel'); // document.getElementById("itemsmodel");
var modelsNum = ~~$numberOfQuestions.val(); // parseInt(models.value);
var curModels = $modelsTable.children().length; // modelsTable.childElementCount
var delta = modelsNum - curModels;
// While too few, add more
while (delta > 0) {
var $input = $('<div>').addClass('editor-field'); // document.createElement("div"); .className = "editor-field";
var template = $('#ListTemplate').html(); // Fetch the template from a script block (id="ListTemplate")
$input.html(template); // input.innerHTML =
$modelsTable.append($input); // modelsTable.appendChild(input);
delta--;
}
// While too many, remove the last
while (delta++ < 0) {
$modelsTable.children().last().remove(); // modelsTable.removeChild(modelsTable.lastChild);
}
}).change(); // Trigger an initial change event so it runs immediately
});
Notes/tips:
Place any JS in the page, at the bottom of the view, as it is easier to find. It does not matter where the #section Scripts is as the master page determines where it is injected on the final page.
Always use single quotes (') in Javascript constants by default, so that nested strings can be " which are more often required than 's. Just a good habit to get into. In fact if you had used them your code may have worked as you have added \ escaping to the quotes which will mess up the Razor processing
e.g.:
= '#Html.ListBoxFor(x => x.TagIdList, (MultiSelectList)ViewBag.Tags, new { #class = "chzn-select", data_placeholder = "Tags..." })';
If you add a #RenderSection("styles", required: false) to your master page(s) you can do the same thing for CSS as you do for scripts (ensuring all CSS is loaded in the header (for consistency). Just place them in a #section styles block.
e.g.
<head>
...
#Styles.Render("~/Content/css")
#RenderSection("styles", required: false)
...
</head>
~~ is a handy (and fast) alternative to parseInt to convert values to integers.
Use $ as a prefix for jQuery object variables. This makes it easier to remember when to use jQuery methods vs DOM properties.
Test controller code:
private MultiSelectList TagList()
{
var items = new List<KeyValuePair<int, string>>() {
new KeyValuePair<int, string>(1, "MVC"),
new KeyValuePair<int, string>(2, "jQuery"),
new KeyValuePair<int, string>(3, "JS"),
new KeyValuePair<int, string>(4, "C#"),
new KeyValuePair<int, string>(5, "PHP")
};
MultiSelectList list = new MultiSelectList(items, "key", "value", null);
return list;
}
// Get request starts with one list
public ActionResult Test()
{
ExamModel vm = new ExamModel()
{
NumberOfQuestions = 1,
TagIdList = new List<int>()
};
ViewBag.Tags = TagList();
return View(vm);
}
[HttpPost]
public ActionResult Test(ExamModel model)
{
ViewBag.Tags = TagList();
return View(model);
}
If it's a static JavaScript file and you are not generating it dynamically with razor view engine It won't work because in this case there is no processing performed on a server side. It is the same as accessing static html page/css file/image and etc...
On the other hand if this JavaScript is part of some Razor view, which means that it gets rendered by razor view engine, when you have return View() (or anything like that) in your controller action, than this code should work.
The problem is, java script files are not processed by server, so you won't be able to insert anything in those using ASP.NET MVC. Razor files on the other hand are processed on server so you can insert data into those (either through view bag or model).
One way is:
.cshtml:
<script>
var someVariable = '#model.data';
</script>
then use this variable in your javascript file:
function someFunction(){
var myData = window.someVariable;
}
The other way is to have all javascript in .cshtml file and render it as a partial view.
#Html.Partial("Path/to/javascript/in/razor/view")
edit: seeing your code, this will not help you very much.
If you want to dynamically add/remove dom elements, you will have to do it with javascript: either generate them with "document.createElement()" or load them via ajax if you want some server side processing.
#Html.ListBoxFor
is a server side helper that generates tag and fills it up depending on the parameters. You can do that with javascript as well.
Friends,
I am trying to use DyGraph in my application. Please look at the code below -
<head>
<meta http-equiv="X-UA-Compatible" content="IE=EmulateIE7; IE=EmulateIE9">
<title>crosshairs</title>
<script type="text/javascript" src="dygraph-combined.js"></script>
<script type="text/javascript" src="data.js"></script>
</head>
The code uses data.js file containing function to get some static data.
I want data.js to be generated using a controller method so that it will generate data using database.
Can anybody help me out to resolve this issue.
Thanks for sharing your valuable time.
You could define a controller action:
public ActionResult Data()
{
// Obviously this will be dynamically generated
var data = "alert('Hello World');";
return JavaScript(data);
}
and then:
<script type="text/javascript" src="<%= Url.Action("Data", "SomeController") %>"></script>
If you have some complex script that you don't want to generate in the controller you could follow the standard MVC pattern by defining a view model:
public class MyViewModel
{
... put required properties
}
a controller action which would populate this view model and pass it to the view:
public ActionResult Data()
{
MyViewModel model = ...
Response.ContentType = "application/javascript";
return PartialView(model);
}
and finally a view which in this case will be the javascript representation of the view model (~/Views/SomeController/Data.ascx):
<%# Control
Language="C#"
Inherits="System.Web.Mvc.ViewUserControl<MyViewModel>" %>
alert(<%= new JavaScriptSerializer().Serialize(Model.Name) %>);
Full Disclosure
This answer is copy/pasted from another question:
Dynamically generated Javascript, CSS in ASP.NET MVC
This answer is similar to other answers here.
This answer uses cshtml pages rather than ascx controls.
This answer offers a View-Only solution rather than a Controller-Only solution.
I don't think my answer is 'better' but I think it might be easier for some.
Dynamic CSS in a CSHTML File
I use CSS comments /* */ to comment out a new <style> tag and then I return; before the closing style tag:
/*<style type="text/css">/* */
CSS GOES HERE
#{return;}</style>
Dynamic JS in a CSHTML File
I use JavaScript comments // to comment out a new <script> tag and then I return; before the closing script tag:
//<script type="text/javascript">
JAVASCRIPT GOES HERE
#{return;}</script>
MyDynamicCss.cshtml
#{
var fieldList = new List<string>();
fieldList.Add("field1");
fieldList.Add("field2");
}
/*<style type="text/css">/* */
#foreach (var field in fieldList) {<text>
input[name="#field"]
, select[name="#field"]
{
background-color: #bbb;
color: #6f6f6f;
}
</text>}
#{return;}</style>
MyDynamicJavsScript.cshtml
#{
var fieldList = new List<string>();
fieldList.Add("field1");
fieldList.Add("field2");
fieldArray = string.Join(",", fieldList);
}
//<script type="text/javascript">
$(document).ready(function () {
var fieldList = "#Html.Raw(fieldArray)";
var fieldArray = fieldList.split(',');
var arrayLength = fieldArray.length;
var selector = '';
for (var i = 0; i < arrayLength; i++) {
var field = fieldArray[i];
selector += (selector == '' ? '' : ',')
+ 'input[name="' + field + '"]'
+ ',select[name="' + field + '"]';
}
$(selector).attr('disabled', 'disabled');
$(selector).addClass('disabled');
});
#{return;}</script>
No Controller Required (using Views/Shared)
I put both of my dynamic scripts into Views/Shared/ and I can easily embed them into any existing page (or in _Layout.cshtml) using the following code:
<style type="text/css">#Html.Partial("MyDynamicCss")</style>
<script type="text/javascript">#Html.Partial("MyDynamicJavaScript")</script>
Using a Controller (optional)
If you prefer you may create a controller e.g.
<link rel="stylesheet" type="text/css" href="#Url.Action("MyDynamicCss", "MyDynamicCode")">
<script type="text/javascript" src="#Url.Action("MyDynamicJavaScript", "MyDynamicCode")"></script>
Here's what the controller might look like
MyDynamicCodeController.cs (optional)
[HttpGet]
public ActionResult MyDynamicCss()
{
Response.ContentType = "text/css";
return View();
}
[HttpGet]
public ActionResult MyDynamicJavaScript()
{
Response.ContentType = "application/javascript";
return View();
}
Notes
The controller version is not tested. I just typed that off the top of my head.
After re-reading my answer, it occurs to me it might be just as easy to comment out the closing tags rather than use the cshtml #{return;}, but I haven't tried it. I imagine it's a matter of preference.
Concerning my entire answer, if you find any syntax errors or improvements please let me know.
Look at the below code, this JavaScript is used to take a string (in a language other than English) and convert it into English.
<script type="text/javascript">
google.load("language", "1");
function initialize() {
var content = document.getElementById('translation');
// Setting the text in the div.
content.innerHTML = '<div id="text">HELLO WORLD<\/div>
<div id="translation"/>';
// Grabbing the text to translate
var text = document.getElementById("text").innerHTML;
// Translate from Spanish to English, and have the callback of
// the request put the resulting translation in the
// "translation" div. Note: by putting in an empty string for
// the source language ('es') then the translation will
// auto-detect the source language.
google.language.translate(text, '', 'en', function(result) {
var translated = document.getElementById("translation");
if (result.translation) {
translated.innerHTML = result.translation;
}
});
}
google.setOnLoadCallback(initialize);
</script>
I want that the string "HELLO WORLD" must be entered by user at run time in a text field and then that string is passed to the div id text. So is this possible?
Hope you are referring to the document below:
http://code.google.com/apis/language/translate/v1/getting_started.html
Please refer to the section "Getting Started" where it says about "Signing up for an API key". This needs to be done before you could implement the code in your page.
Once done, make the modification to the script file which you include in the html page with your key.
Here, replace your key with "MY_KEY_STRING" in the bottom code and get started.
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">

<script src="https://www.google.com/jsapi?key=MY_KEY_STRING"></script>

function initialize() {
//Show the translate button
document.getElementById("translateButton").style.display = "";
}
google.setOnLoadCallback(initialize);
function translate() {
var text = document.getElementById("fromText").value;
google.language.translate(text, 'es', 'en', function(result) {
var translated = document.getElementById("toText");
if (result.translation) {
translated.innerHTML = result.translation;
}
});
}
</script>
</head>
<body style="font-family: Arial;border: 0 none;">
From:<input type="text" id="fromText"/>
To:<span id="toText"></span>
<input type="button" value="Translate" onclick="translate()" style="display: none;" id="translateButton">
</body>
</html>
HTML:
<form id="translate">
<textarea id="translate-me"></textarea>
<input type="submit" />
</form>
JavaScript:
var form = document.getElementById('translate')
var textarea = document.getElementById('translate-me')
form.onsubmit = function () {
google.language.translate(textarea.value, ...)
return false; // prevent default action (form submission)
}
Using jQuery or something similar would make this easier, of course.
I know you cant save javascript variables into server side variables (vbscript) directly, but is there a way around this like saving java script variables into html hidden inputs then using javascript to post. Is this possible? If not what else can i do? Below is my code so far get the value of a drop down list - javascript
function selectedDatabase() {
select_temp = form1.elements["selection"];
select_index = select_temp.selectedIndex;
select_text = select_temp.options[select_index].text;
}
Below is the HTML code
<center><select id="selection" onchange="selectedDatabase()">
<option>Movies</option>
<option>Movies 2</option>
<option>New Movies</option>
<option>New Movies 2</option>
</select></center>
</td></tr>
What you're looking for is called ajax. You can do it manually, or better use a JavaScript library such as MooTools, jQuery, or Prototype.
Check out Google University's Ajax tutorial. I would avoid w3schools' tutorials.
Just to cover all the bases, why can't you just have the user submit the form?
Also, you could do this with cookies, though you won't get the cookie values on the server until the next GET or POST from the user.
It is Possible to store javascript variable values into server side variable. All you have to do is to implement "System.Web.UI.ICallbackEventHandler" class.
Below is the code demonstrating how to do it.
In aspx Page:
<html xmlns="http://www.w3.org/1999/xhtml">
<head id="Head1" runat="server">
<title>Client Calback Example</title>
<script type="text/ecmascript">
function LookUpStock()
{
var lb=document.getElementById("tbxPassword");
var product=lb.value;
CallServer(product,"");
}
function ReceiveServerData(rValue){
}
</script>
</head>
<body>
<form id="form1" runat="server">
<div>
<input type="password" id="tbxPassword" />
<input type="Button" onclick="LookUpStock">Submit</button>
</div>
</form>
</body>
**
In Code Behind (CS) Page
**
public partial class _Default : System.Web.UI.Page,System.Web.UI.ICallbackEventHandler
{
protected String returnValue;
protected void Page_Load(object sender, EventArgs e)
{
String cbReference = Page.ClientScript.GetCallbackEventReference
(this,"arg", "ReceiveServerData", "context");
String callbackScript;
callbackScript = "function CallServer(arg, context)" +
"{ " + cbReference + ";}";
Page.ClientScript.RegisterClientScriptBlock(this.GetType(),
"CallServer", callbackScript, true);
}
public void RaiseCallbackEvent(String eventArgument)
{
if(eventArgument == null)
{
returnValue = "-1";
}
else
{
returnValue = eventArgument;
}
}
public String GetCallbackResult()
{
return returnValue;
}
}
Now you can get the JavaScript variable "product" value into Server side variable "returnValue".
