My default action code:
public ViewResult Act(int? id)
{
if (id == null)
ViewData["p"] = GetDefaultView();
else
ViewData["p"] = GetEditView((int)id);
return View("Index");
}
My Index view code:
<!DOCTYPE html><html><head></head><body>
<div id="content">#Html.Raw(ViewData["p"])</div></body></html>
How it is possible to use instead of ViewData a string ? How I can update #content only by means of $.ajax?
Before being able to use the $.ajax function you will first need to render a view which includes the jquery.js script:
<!DOCTYPE html>
#{ Layout = null; }
<html>
<head>
</head>
<body>
<div id="content"></div>
<!-- TODO: Adjust your proper jquery version here: -->
<script type="text/javascript" src="~/scripts/jquery.js"></script>
<script type="text/javascript">
$.ajax({
url: '#Url.Action("act")',
data: { id: 123 },
success: function(result) {
$('#content').html(result);
}
});
</script>
</body>
</html>
then you should adapt your Act controller action so that it returns some partial view or a Content result:
public ActionResult Act(int? id)
{
if (id == null)
{
return Content("<div>id was null</div>");
}
return Content("<div>id value is " + id.Value.ToString() + "</div>");
}
If you want to return a string, you could change your controller to return a ContentResult.
public ContentResult Act(int? id)
{
string html = "";
if (id == null)
html = GetDefaultView();
else
html = GetEditView((int)id);
var content = new ContentResult();
content.Content = html;
return content;
}

I'm trying to upload files using dropzone.js
View:
#using (Html.BeginForm("SaveMethod", "ControllerName", FormMethod.Post, new { enctype = "multipart/form-data", #class = "dropzone", id = "js-upload-form" }))
........................
<div class="form-inline">
<div class="form-group">
<input type="file" name="MainFile" id="js-upload-files"/>
</div>
<div class="upload-drop-zone" id="drop-zone">
Just drag and drop files here
</div>
<div class="dropzone-previews"></div>
</div>
JS:
var formData = null;
formData = new FormData($form[0]);
dropZone.ondrop = function (e) {
e.preventDefault();
this.className = 'upload-drop-zone';
startUpload(e.dataTransfer.files)
}
dropZone.ondragover = function () {
this.className = 'upload-drop-zone drop';
return false;
}
dropZone.ondragleave = function () {
this.className = 'upload-drop-zone';
return false;
}
var startUpload = function (files) {
for (var i = 0; i < files.length; i++) {
formData.append(files[i].name, files[i]);
}
}
Controller:
[HttpPost]
public JsonResult SaveMethod(TaskManage objTaskManage, HttpPostedFileBase files)
{
}
Now, after submit, i want to have files that was dropped on drop area along with the files attached in upload control. Here, what happens is files giving me null and when i use Request.Files["MainFile"] i get only the files dropped on dropzone area, it doesn't show me the file i have upload to control.
I'm not able to find out the issue. Any help is really appreciated.
File upload in ASP.NET MVC using Dropzone JS and HTML5
You can download the latest version from the official site here http://www.dropzonejs.com/ and also we can install using the nuget package manage console by the following command Package Manager Console
PM> Install-Package dropzone
Now create a bundle for your script file in BundleConfig.cs
bundles.Add(new ScriptBundle("~/bundles/dropzonescripts").Include(
"~/Scripts/dropzone/dropzone.js"));
Similarly add the dropzone stylesheet in the BundleConfig.cs
bundles.Add(new StyleBundle("~/Content/dropzonescss").Include(
"~/Scripts/dropzone/css/basic.css",
"~/Scripts/dropzone/css/dropzone.css"));
Now add the bundle reference in your _Layout page
View Page:
<div class="jumbotron">
<form action="~/Home/SaveUploadedFile" method="post" enctype="multipart/form-data" class="dropzone" id="dropzoneForm" style="width: 50px; background: none; border: none;">
<div class="fallback">
<input name="file" type="file" multiple />
<input type="submit" value="Upload" />
</div>
</form>
</div>
Controller:
public ActionResult SaveUploadedFile()
{
bool isSavedSuccessfully = true;
string fName = "";
try{
foreach (string fileName in Request.Files)
{
HttpPostedFileBase file = Request.Files[fileName];
//Save file content goes here
fName = file.FileName;
if (file != null && file.ContentLength > 0)
{
var originalDirectory = new DirectoryInfo(string.Format("{0}Images\\WallImages", Server.MapPath(#"\")));
string pathString = System.IO.Path.Combine(originalDirectory.ToString(), "imagepath");
var fileName1 = Path.GetFileName(file.FileName);
bool isExists = System.IO.Directory.Exists(pathString);
if (!isExists)
System.IO.Directory.CreateDirectory(pathString);
var path = string.Format("{0}\\{1}", pathString, file.FileName);
file.SaveAs(path);
}
}
}
catch(Exception ex)
{
isSavedSuccessfully = false;
}
if (isSavedSuccessfully)
{
return Json(new { Message = fName });
}
else
{
return Json(new { Message = "Error in saving file" });
}
}
Now add the following script to your view page at the and in script tag.
//File Upload response from the server
Dropzone.options.dropzoneForm = {
init: function () {
this.on("complete", function (data) {
//var res = eval('(' + data.xhr.responseText + ')');
var res = JSON.parse(data.xhr.responseText);
});
}
};
Here you can see the response from server.
Hi everyone i am trying to register new account on my local openfire server using strophe.js and strophe.register.js plugin by following the steps for registration provide on many websites.But i get error in my strophe.register.js file at line var auth_old = conn.authenticate.bind(conn); that conn.authenticate is undefined
below is the my code
code of my js file
$(document).ready(function () {
var conn = new Strophe.Connection(
"http://jabber.local/http-bind");
console.log(conn);
var callback = function (status) {
if ( status === Strophe.Status.REGISTERING ) {
console.log('REGISTERING')
conn.authenticate();
}
else if ( status === Strophe.Status.REGIFAIL ) {
console.log('REGIFAIL')
}
else if ( status === Strophe.Status.REGISTER ) {
console.log('REGISTER')
conn.register.fields.username = "joe"
conn.register.fields.password = "doe"
conn.register.submit();
}
else if ( status === Strophe.Status.SUBMITTING ) {
console.log('SUBMITTING')
}
else if ( status === Strophe.Status.SBMTFAIL ) {
console.log('SBMTFAIL')
console.log('Something went wrong...');
}
else if ( status === Strophe.Status.REGISTERED ) {
console.log('REGISTERED')
console.log('Your account has been created successfully and is ready to use!');
}
}
conn.register.connect("example.com", callback);
});
and the html file code is
<html>
<head>
<script src='http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.js'></script>
<script src='../scripts/strophe.js'></script>
<script type="text/javascript" src="../scripts/strophe.register.js"></script>
<script src='../scripts/flXHR.js'></script>
<script src='../scripts/strophe.flxhr.js'></script>
<link rel='stylesheet' href='hello.css'>
<script src='hello.js'></script>
</head>
<body>
<h1>Hello</h1>
<div id='log'>
</div>
<!-- login dialog -->
<div id='login_dialog' class='hidden'>
<label>JID:</label><input type='text' id='jid'>
<label>Password:</label><input type='password' id='password'>
</div>
</body>
</html>
can enyone tell my why this happend and how to solve this.One more thing i also comment the lines that most site said to do.
/* if (register.length === 0) {
conn._changeConnectStatus(Strophe.Status.REGIFAIL, null);
return true;
}*/
this.enabled = true;
Just noticed that you are using the older version of the plugin. Please update the strophe.register.js from https://github.com/metajack/strophejs-plugins/blob/master/register/strophe.register.js
I have checked the latest version it does not have below line
var auth_old = conn.authenticate.bind(conn);
Good morning everyone. I tried creating a site that could get information from another page and feed the response into a div tag, but it didnt work. I checked with a very similar one i learnt from. Here is the HTML code.
<html>
<head>
<script>
function checkit(){
var samxml; var username;
if (window.XMLHttpRequest){
samxml = new XMLHttpRequest();}
else {
samxml = new ActiveXObject("Microsoft.XMLHTTP");
}
samxml.onreadystatechange = function() {
if (samxml.readyState == 4 && samxml.status == 200){
document.getElementById("check").innerHTML = samxml.responseText;}
}
username = document.getElementById("username").value;
samxml.open("POST", "check.php",true);
samxml.send( "username" );
}
}
</script>
</head>
<body>
<form>
<label for ="username">User ID:</label>
<input type = "text" name = "username" id = "username"/>
<div id = "check"></div>
<button type = "button" onclick = "checkit()">Check</button>
</form>
</body>
</html>
Here is the PHP page:
//php file
<?php
$user = $_POST["username"];
if ($user == "samuel") {
echo "Hmm. Chosen! Choose another one";}
else {
echo "Nice one";}
?>
Thanks so much.
In his blog post, Christian Cantrell shows how to use STORAGE_VOLUME_MOUNT in ActionScript.
He has written a Flex app called FileTile.
I would like to see a JavaScript alert box that says “You have inserted “ + e.storageVolume.name, and “You have removed a storage volume”.

I used the jQuery autocompletion for my Struts2 application.
Pratically, my action made a list of strings that jQuery use. This is the script:
$().ready(function() {
$("#tag").autocomplete("/myAction/Action", {
multiple : true,
autoFill : true,
minChars:1
});
});
During typing appear the box with the suggestions. The problem is that the box render another value,
exactly render the code of my JSP ( links to CSS for the autocomplete plug-in).
How can I solve this?
This is my JSP:
<html>
<head>
<script src="<%=request.getContextPath()%>/scripts/jquery-latest.js"></script>
<link rel="stylesheet" href="<%=request.getContextPath()%>/scripts/main.css" type="text/css" />
<link rel="stylesheet" href="<%=request.getContextPath()%>/scripts/jquery.autocomplete.css" type="text/css" />
<script type="text/javascript" src="<%=request.getContextPath()%>scripts/jquery.bgiframe.min.js"></script>
<script type="text/javascript" src="/<%=request.getContextPath()%>/query.dimensions.js"></script>
<script type="text/javascript" src="<%=request.getContextPath()%>/scripts/jquery.autocomplete.js"></script>
<script type="text/javascript">
$().ready(function() {
$("#tag").autocomplete("/myAction/Action", {
multiple : true,
autoFill : true,
minChars:1
});
});
</script>
</head>
<body>
<s:form action="Action" theme="simple">
<s:iterator value="elencoMateriali" var="asd">
<s:property value="#asd" escape="false"/>
</s:iterator>
<s:textfield id="tag" name="tagField" label="tag" />
</s:form>
</body>
I think it's too late for an answer, but the probles is still remaining in Struts2. I have made some modifications to solve such problem:
Copy the jquery.struts2.js file into you js path.
Edit the jquery.struts2.js fil and look for 'success: function(data)' in the handle of the Autocompleter Widget, and replace the function for the next one:
success: function(data) {
var x = 0;
if (data[o.list] !== null) {
var isMap = false;
if (!$.isArray(data[o.list])) {
isMap = true;
}
var result = [];
$.each(data[o.list], function(j, val) {
if (isMap) {
result.push({
label: val.replace(
new RegExp(
"(?![^&;]+;)(?!<[^<>]*)(" +
$.ui.autocomplete.escapeRegex(request.term) +
")(?![^<>]*>)(?![^&;]+;)", "gi"
), "<strong>$1</strong>" ),
value: val,
id: j
});
}
else {
if (o.listkey !== undefined && o.listvalue !== undefined) {
result.push({
label: val[o.listvalue].replace(
new RegExp(
"(?![^&;]+;)(?!<[^<>]*)(" +
$.ui.autocomplete.escapeRegex(request.term) +
")(?![^<>]*>)(?![^&;]+;)", "gi"
), "<strong>$1</strong>" ),
value: val[o.listvalue],
id: val[o.listkey]
});
}
else {
result.push({
label: data[o.list][x].replace(
new RegExp(
"(?![^&;]+;)(?!<[^<>]*)(" +
$.ui.autocomplete.escapeRegex(request.term) +
")(?![^<>]*>)(?![^&;]+;)", "gi"
), "<strong>$1</strong>" ),
value: data[o.list][x],
id: data[o.list][x]
});
}
}
x++;
});
response(result);
}
}
Now, if you subscribe a onSelectTopics method on your jsp code, you will have a new item.id element available, so you can set the id value into a hidden o whatever you want.
Now, your autocompleter show a list with the strong word, fills the input with the selection, and mantains the id in a variable you can catch.
Remember to add the modified js in the include header section.
<%# taglib prefix="s" uri="/struts-tags" %>
<%# taglib prefix="sx" uri="/struts-dojo-tags" %>
<s:form action="ActionJson" theme="simple">
<s:url id="elencoFuffa" action="ActionJSON"/>
<sx:autocompleter id="autocompleter" name="materiale" loadOnTextChange="true" preload="false" href="%{elencoFuffa}" size="24" loadMinimumCount="1" showDownArrow="false" cssClass="dropDown" onchange="submit();"/>
<s:submit value="Prosegui"/>
<s:property value="luoghiSmaltimento"/>
</s:form>
Now, the Action:
public class Action extends ActionSupport {
private String materiale;
private String luoghi;
private List<String> elencoMateriali;
private Map<String, String> json;
public String execute() throws Exception {
System.out.println("------------------" + materiale);
return SUCCESS;
}
public String getMateriali() throws Exception {
MaterialiDAO dao = new MaterialiDAO();
List<Materiali> toResult = new ArrayList<Materiali>();
toResult = dao.findAll();
elencoMateriali = new ArrayList<String>();
Iterator i = toResult.iterator();
while (i.hasNext()) {
Materiali m = (Materiali) i.next();
elencoMateriali.add(m.getValueNomemateriale());
}
return SUCCESS;
}
public String getJson() throws Exception {
json = new HashMap<String, String>();
if (materiale != null && materiale.length() > 0) {
MaterialiDAO dao = new MaterialiDAO();
List<Materiali> materiali = dao.findByLikeValue(materiale);
for (Materiali m : materiali) {
json.put(m.getValueNomemateriale(), "" + m.getIdMateriali());
}
}
return SUCCESS;
}
public String trovaLuogo() throws Exception {
LuoghismalDAO daoL = new LuoghismalDAO();
MaterialiDAO daoM = new MaterialiDAO();
Materiali m = daoM.findByMaterialiName(materiale);
if (m != null) {
luoghi = m.getLuoghismal().getValueDescrluogo();
return SUCCESS;
} else {
luoghi = "-- Scegliere un materiale --";
return SUCCESS;
}
}
/* Getters and setters */
At the end the struts.xml
<action name="ActionJSON" class="it.action.Action"
method="getJson">
<result type="json">
<param name="root">json</param>
</result>
</action>
