I got this code in my view that is used for a drag and drop function:
<div class="container">
<form action="~/Home/SaveUploadedFile" method="post"
enctype="multipart/form-data" class="dropzone"
id="dropzoneForm">
</form>
When an image gets dropped in the div the SaveUploadedFile gets triggered. The model im using in the view contains a #Model.Namethat I would love to pass along to the method.
Can I somehow accomplish this in the above code or is it more complicated?
You could put a hidden input.
<form action="~/Home/SaveUploadedFile" method="post"
enctype="multipart/form-data" class="dropzone"
id="dropzoneForm">
<input type="hidden" name="fileName" value="#Model.Name" />
<input id="btn_drop" type="button" value="Drop"/>
...
</form>
Then in jQuery
$('#btn_drop').on('click', function(){
$('#dropzoneForm').submit();
});

I would like to let the user pick a time using a uib-timepicker tag and POST the result to my server (with a submit button for example).
<form class="simple_form vertical_form"
data-type="json" id="my_form"
action="url_to_post"
accept-charset="utf8"
data-remote="true"
method="post">
<div class="field">
<uib-timepicker
name="my_time"
ng-model="event.my_model"
hour-step="1"
minute-step="15"
show-meridian="true">
</uib-timepicker>
</div>
<div>
<input type="submit" value="Validate" class="btn btn-success">
</div>
</form>
But when I check to content of the POST method it is empty (I don't get the "my_time" key as I would expect. I guess it is because a "uib-timepicker" does not exactly work as an input field. But I feel like there must be a way to POST the content of that tag.
Thanks for helping!
I solved this issue by adding hidden input elements with binding to the time picker:
<uib-timepicker ng-model="ServiceRestoredTime" name="ServiceRestoredTime" ng-change="changed()" hour-step="hstep" minute-step="mstep" show-meridian="false" show-spinners="false"></uib-timepicker>
<input type="hidden" name="ServiceRestoredTimeParam" value="{{ServiceRestoredTime | date:'HH:mm' }}">
I have a kendo grid with a button in it. When the button is pressed it opens up a popup with a file-select input and a button so that the user can save a image. Im using a normal form with a submit button to post my form to my controller. Everything works fine the right data arrives to the controller but then the page refreshes. I just want the popup to close and the grid and the whole page behind the popup to just stay as it is. Here is my controller:
[HttpPost]
public ActionResult SaveData(HttpPostedFileBase file, string id)
{
iResourceModel.SaveData(file, file.FileName);
return null;
}
and my html form:
<div id="details-container">
<form action="/Home/SaveData" method="post" enctype="multipart/form-data">
<span>Select file:</span><input type="file" name="file" id="file">
<input type="text" value=' + dataItem.ResourceId +' name="id" id="id" hidden/>
<button type="submit" id="" >Save file</button>
</form>
</div>
Page reloading after submitting a form is normal behavior. If you want to stop it, you can use jQuery and submit the form in the background.
You can find the jQuery form plugin here : http://plugins.jquery.com/form/
For your case :
<div id="details-container">
<form action="/Home/SaveData" method="post" enctype="multipart/form-data" id="myForm">
<span>Select file:</span><input type="file" name="file" id="file">
<input type="text" value=' + dataItem.ResourceId +' name="id" id="id" hidden/>
<button type="submit" id="" >Save file</button>
</form>
</div>
<script>
$(document).ready(function() {
$('#myForm').ajaxForm(function() {
alert("File uploaded!");
});
});
</script>
I have a fairly simple form created in a partial view and loading the form on a jquery dialog. The view is tightly bound to a model. When the user clicks on the submit button with out entering any inputs, I need to show the validation messages.
<div>
<form method="post" enctype="multipart/form-data" id="ssimForm" action="Home/ProcessUploadedFile"
onsubmit="return false;">
<div>
<h3>
Select the file to be uploaded :</h3>
<span>
<input type="file" name="UploadFileName" id="UploadFileName" /></span>
</div>
<div>
<h3>
Select the date range :</h3>
<span class="uslabel">From Date(MM/dd/yyyy): </span>
<input class="usdate" id="usfromdate" name="StartDate" type="date" />
<span class="uslabel">To Date(MM/dd/yyyy): </span>
<input class="usdate" id="ustodate" name="EndDate" type="date" />
</div>
<div>
<br />
<input type="submit" id="submitButton" name="submitButton" value="Process File" />
</div>
#Html.ValidationSummary()
<div class="message-success">
<span>#ViewBag.Confirmation</span>
</div>
<div class="message-error">
<span>#ViewBag.Error</span>
</div>
</form>
</div>
Now comes the actual problem. when I submit the form I am able to see the validationSummary object populated with the messages, but they are not getting rendered on the screen.
I am able to see the messages if I replace the content of the dialog with the response from the jquery ajax call, that fetches the entire view from the server side. I do not want to take this approach as I beleive this is not the correct way to return validation summary in MVC.
Am I missing something? Any help is appreciated.
I don't know why you don't have the #using (Html.BeginForm()) { } block.
Here is my blog post for a quick and easy way to set up Validation Summary + Unobtrusive Validation for MVC3+.

Dazed and confused here... The field in question is a boolean, and I want the UI to be a checkbox (or a yes/no or on/off jQuery slider). Each time I try to add in this checkbox input, I end up getting a
Microsoft JScript runtime error: DOM Exception: HIERARCHY_REQUEST_ERR (3)
error.
Here's the HTML+Razor
<div data-role="fieldcontain">
<fieldset data-role="controlgroup">
<legend>End Game:</legend>
#Html.TextBoxFor(model => model.HandicapSession.WinByTwo, new { #type="checkbox" })
<label for="WinByTwo">Win By Two?</label>
</fieldset>
</div>
Here's the generated HTML:
<div data-role="fieldcontain">
<fieldset data-role="controlgroup">
<legend>End Game:</legend>
<input data-val="true" data-val-required="The WinByTwo field is required." id="HandicapSession_WinByTwo" name="HandicapSession.WinByTwo" type="checkbox" value="False" />
<label for="WinByTwo">Win By Two?</label>
</fieldset>
</div>
Apparently this error occurs when there are conflicting or overlapping id's as jQuery Mobile creates its checkbox widget
$.widget( "mobile.checkboxradio", $.mobile.widget, { ...etc...
But how do I use the HTML and/or razor to make a simple checkbox work in jQuery Mobile?
If the problem with jQuery Mobile really is duplicate names for the HTML tags, then you'll have to render your own input type=checkbox tag in HTML, as the ASP.NET MVC Html.CheckBoxFor helper method will render an input type=hidden tag with a duplicate name value. See this post for a discussion.
The hidden form tag is there because if you submit an unchecked checkbox to the server, the form value for that field isn't included. So a hidden input tag is included with value=false so that if the checkbox is unchecked, the value false is still submitted. The model binding process in MVC will filter out the duplicate form values for you, but if you're having a client-side problem with the duplicate name attributes, you'll have to render your own checkbox and label in HTML, then handle the fact that no value will be submitted for the HandicapSession.WinByTwo property when the box is unchecked. If no other property for HandicapSession is submitted, then that whole object will be null.
So, you can manually create the checkbox input and still load the checked and value attributes from your model, as desired, but you can run into model binding problems where the value for WinByTwo will still be false even when the box is checked.
Note also that the for attribute on your label doesn't match the ID of the checkbox in your sample. You need the full HandicapSession_WinByTwo.
The following manually creates the input tags:
<link rel="stylesheet" href="http://code.jquery.com/mobile/1.0a4.1/jquery.mobile-1.0a4.1.min.css" />
<script type="text/javascript" src="http://code.jquery.com/mobile/1.0a4.1/jquery.mobile-1.0a4.1.min.js"></script>
<div data-role="page">
<div data-role="content">
<div data-role="fieldcontain">
<fieldset data-role="controlgroup">
<legend>End Game:</legend>
<input type="checkbox" id="HandicapSession_WinByTwo" name="HandicapSession.WinByTwo" #(Model.HandicapSession.WinByTwo ? "checked=checked" : "") value="#(Model.HandicapSession.WinByTwo.ToString().ToLower())" />
<label for="HandicapSession_WinByTwo">Win By Two?</label>
</fieldset>
</div>
</div>
</div>
The HTML output is as follows for a checked checkbox on load:
<div data-role="page">
<div data-role="content">
<div data-role="fieldcontain">
<fieldset data-role="controlgroup">
<legend>End Game:</legend>
<input type="checkbox" id="HandicapSession_WinByTwo" name="HandicapSession.WinByTwo" checked=checked value="true" />
<label for="HandicapSession_WinByTwo">Win By Two?</label>
</fieldset>
</div>
</div>
</div>
The best would be just to use the MVC helper methods, so I'm not sure if you'd tried the following. The default Html.CheckBoxFor and Html.LabelFor helper methods work with jQuery Mobile 1.0a4.1 or 1.1.0 just fine. The following works for me:
<link rel="stylesheet" href="http://code.jquery.com/mobile/1.0a4.1/jquery.mobile-1.0a4.1.min.css" />
<script type="text/javascript" src="http://code.jquery.com/mobile/1.0a4.1/jquery.mobile-1.0a4.1.min.js"></script>
<div data-role="page">
<div data-role="content">
#using (Html.BeginForm())
{
<div data-role="fieldcontain">
<fieldset data-role="controlgroup">
<legend>End Game:</legend>
#Html.CheckBoxFor(m => m.HandicapSession.WinByTwo)
#Html.LabelFor(m => m.HandicapSession.WinByTwo, "Win By Two?")
<input type="submit" id="SubmitForm" value="submit" />
</fieldset>
</div>
}
</div>
</div>
This produces the HTML output:
<div data-role="page">
<div data-role="content">
<form action="/Mobile/Mobile" method="post">
<div data-role="fieldcontain">
<fieldset data-role="controlgroup">
<legend>End Game:</legend>
<input checked="checked" data-val="true" data-val-required="The WinByTwo field is required." id="HandicapSession_WinByTwo" name="HandicapSession.WinByTwo" type="checkbox" value="true" />
<input name="HandicapSession.WinByTwo" type="hidden" value="false" />
<label for="HandicapSession_WinByTwo">Win By Two?</label>
<input type="submit" id="SubmitForm" value="submit" />
</fieldset>
</div>
</form>
</div>
</div>
Fix might be pretty simple.
Choice 1: Go scorched earth and turn off Ajax based navigation. This will ensure that unique IDs stay unique. This will ensure that you never encounter this issue again. Only downside is that you lose the pretty little transitions from page to page (someone call the whambulance). You can do this by setting up a global configuration script...
script src="jquery.js"
script src="custom-scripting.js"
script src="jquery-mobile.js"
inside that you'll override the ajax settings to disable them...
$(document).bind("mobileinit", function(){
$.mobile.ajaxEnabled = false;
});
Choice 2: Call pages that are going to require this uniqueness with a link that has an attribute of rel='external' or target='_black' which will accomplish the same thing without disabling all ajax based navigation. If you are reaching the page as a results of a form post, you can use data-ajax='false' on the form tag to accomplish a clean load.
.I have a div tag that is also divided into two divs. here is the code:
<div>
<div id="search">
<form id="try" method="post">
Batch: <input id="batch" name="batch" type="text"/>Dept: <input id="dept" name="dept" type="text"><input type="submit"/>
</div>
<div id="receiver">
</div>
</div>
I have placed a search option in the div named "search" using post method. what i want to do is that when i click the submit button the page to receive the values will appear on the div named "receiver".
is this possible? if it is, please help..
The ways you have for this are:
1 - The simplest - instead of a div - use an IFrame like this
<div id="search">
<form id="try" method="post" target="receiver" action="url-to-server-Page">
Batch: <input id="batch" name="batch" type="text"/>
Dept: <input id="dept" name="dept" type="text" />
<input type="submit"/>
</form>
</div>
<iframe name="receiver" id="receiver"></iframe>
</div>
The disadvantage in this case is that the search-result that come in this case from url-to-server-page - is a complete and independent HTML page that is nested in your search page.
It is not effected by styles of the parent page, and the communication between them for JavaScript operations is rather combersome.
2 - with some JavaScript skills you can use AJAX.
There are many libraries on the net that can help you do it in very few lines of code.
jQuery is the simplest, although it's the one I like least...
http://jquery.com/
3 - use a full round-trip
<div id="search">
<form id="try" method="post" target="receiver" action="url-to-server-Page">
Batch: <input id="batch" name="batch" type="text"/>
Dept: <input id="dept" name="dept" type="text" />
<input type="submit"/>
</form>
<div id="receiver">
<?php if (isset($_POST['batch']) && isset($_POST['dept'])){
//display search results here.
}
?>
</div>
</div>
You want what's called "AJAX." There are a number of libraries available, such as Google Web Toolkit or jQuery to accomplish what you want.
Can you clarify? Is this a php page and you are posting to self or are you looking to use ajax to populate the div?
If it is php and you post to self then you can simply check if the post has been made inside that div :
<div id="receiver">
<?php if (isset($_POST['batch']) && isset($_POST['dept'])){
//display search results here.
}
?>
</div>
