Posting a form from .cshtml. If the Email Textbox has the value of "Admin" and the Password TextBox has the value of "12345" I want to include an onclick event on the submit button.
I thought about if/else block but what to place in the if condition below where you see question mark (?):
<form class="fvalidate" action="/entry" method="post">
<input type="text" name="Email" class="email required"/>
<input type="password" name="Sifre" class="required" />
#if (?)
{
<input type="submit" value="LOG IN" class="mTop15"
onclick="ibFunc.openBoxOpen('/entry/adv'); return false;" />
}
else
{
<input type="submit" value="LOG IN" class="mTop15" />
}
</form>
How could I accomplish this?
You need to understand the flow of the application and what fires when. You seem to be mixing Client and Server side technology.
The flow should be
Step 1 Submit the form
Step 2 The controller validates the login and works out whether they are admin or not.
Step 3 The controller redirects the user to the /entry or /entry/adv page depending on whether they are an admin or not
Step 4 On the /entry page don't fire the javascript
Step 4a On the /entry/adv page fire the javascript
To answer your question directly. There is nothing you can put in the place of the ? that will do what you want because that is Razor code which is executed on the server before the user has interacted with the page.
Do the control in POST in the controller, when the "Admin" submit the form make an if then use
return RedirectToAction("adv", "entry");

I have a form with id theForm which has the following div with a submit button inside:
<div id="placeOrder"
style="text-align: right; width: 100%; background-color: white;">
<button type="submit"
class='input_submit'
style="margin-right: 15px;"
onClick="placeOrder()">Place Order
</button>
</div>
When clicked, the function placeOrder() is called. The function changes the innerHTML of the above div to be "processing ..." (so the submit button is now gone).
The above code works, but now the problem is that I can't get the form to submit! I've tried putting this in the placeOrder() function:
document.theForm.submit();
But that doesn't work.
How can I get the form to submit?
Set the name attribute of your form to "theForm" and your code will work.
You can use...
document.getElementById('theForm').submit();
...but don't replace the innerHTML. You could hide the form and then insert a processing... span which will appear in its place.
var form = document.getElementById('theForm');
form.style.display = 'none';
var processing = document.createElement('span');
processing.appendChild(document.createTextNode('processing ...'));
form.parentNode.insertBefore(processing, form);
It works perfectly in my case.
document.getElementById("form1").submit();
Also, you can use it in a function as below:
function formSubmit()
{
document.getElementById("form1").submit();
}
document.forms["name of your form"].submit();
or
document.getElementById("form id").submit();
You can try any of this...this will definitely work...
I will leave the way I do to submit the form without using the name tag inside the form:
HTML
<button type="submit" onClick="placeOrder(this.form)">Place Order</button>
JavaScript
function placeOrder(form){
form.submit();
}
You can use the below code to submit the form using JavaScript:
document.getElementById('FormID').submit();
<html>
<body>
<p>Enter some text in the fields below, and then press the "Submit form" button to submit the form.</p>
<form id="myForm" action="/action_page.php">
First name: <input type="text" name="fname"><br>
Last name: <input type="text" name="lname"><br><br>
<input type="button" onclick="myFunction()" value="Submit form">
</form>
<script>
function myFunction() {
document.getElementById("myForm").submit();
}
</script>
</body>
</html>
HTML
<!-- change id attribute to name -->
<form method="post" action="yourUrl" name="theForm">
<button onclick="placeOrder()">Place Order</button>
</form>
JavaScript
function placeOrder () {
document.theForm.submit()
}
If your form does not have any id, but it has a class name like theForm, you can use the below statement to submit it:
document.getElementsByClassName("theForm")[0].submit();
I have came up with an easy resolve using a simple form hidden on my website with the same information the users logged in with. Example: If you want a user to be logged in on this form, you can add something like this to the follow form below.
<input type="checkbox" name="autologin" id="autologin" />
As far I know I am the first to hide a form and submit it via clicking a link. There is the link submitting a hidden form with the information. It is not 100% safe if you don't like auto login methods on your website with passwords sitting on a hidden form password text area...
Okay, so here is the work. Let’s say $siteid is the account and $sitepw is password.
First make the form in your PHP script. If you don’t like HTML in it, use minimal data and then echo in the value in a hidden form. I just use a PHP value and echo in anywhere I want pref next to the form button as you can't see it.
PHP form to print
$hidden_forum = '
<form id="alt_forum_login" action="./forum/ucp.php?mode=login" method="post" style="display:none;">
<input type="text" name="username" id="username" value="'.strtolower($siteid).'" title="Username" />
<input type="password" name="password" id="password" value="'.$sitepw.'" title="Password" />
</form>';
PHP and link to submit form
<?php print $hidden_forum; ?>
<pre>Forum</pre>
I am learning ASP.NET Core (v 2.0). There is a form with a few input text boxes and a submit button. I want to only allow a user to submit a valid form, so while the form is incomplete, I want the Submit button to be disabled.
Is there a way to easily do that using ASP.NET Core model validation?
Thanks.
There is nothing built into ASP.NET MVC that does this for you automatically. The UI pattern you are asking about would require JavaScript coding.
You could download and reference a validation library, like the jQuery Validation Plugin. Then write some JavaScript in your page to check if the form is valid on blur of each of the form inputs by checking $("#myForm").valid(), and only enable the submit button if the form is valid.
See attached snippet for an example.
var $form = $("#myform");
var $submitbutton = $("#submitbutton");
$form.on("blur", "input", () => {
if ($form.valid()) {
$submitbutton.removeAttr("disabled");
} else {
$submitbutton.attr("disabled", "disabled");
}
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery-validate/1.17.0/jquery.validate.min.js"></script>
<form id="myform">
<input type="text" name="text1" required />
<br/>
<input type="text" name="text2" required />
<br/>
<button type="submit" id="submitbutton" disabled>Submit Enabled When Valid</button>
</form>
I have two submit buttons which call the same action method. How can I tell which of these buttons was clicked in the formcollection of the action method (without setting the value property of the buttons)?
HTML code for buttons:
<input type="submit" name="button" />
<input type="submit" name="button" />
Action method as:
public ActionResult submitted(FormCollection form)
{
}
i know how to do if we have a value property, but I just want to try like this without value property. How can this be done?
thanks,
michaeld
The best thing to do, is intercept the click action to set a hidden form variable before the form is submitted, e.g.:
<script language="text/javascript">
$("form input[submit]").click(function() {
$("#buttonSelected").val("some unique value here");
});
</script>
Where you might have a hidden input:
<input type="hidden" id="buttonSelected" name="buttonSelected" />
That way, you can then check the specific "buttonSelected" form value to figure out which button was pressed.
I have a page with a input box and a button, when the user clicks the button i want to redirect to a controller action that has as parameter the value of the input box.
<input id="CodProiect" type="text" />
<input id="Cauta" type="button" value="Cauta" onclick="window.location.href='#Url.Action("Cauta", "Componente", new { CodProiect = "param" })';"/>
How can i get the "param" from the input box ?
You could just use a form with a GET method
<form action="#Url.Action("Cauta", "Componente")" method="GET">
<input id="CodProiect" name="CodProiect" type="text" />
<input id="Cauta" type="submit" value="Cauta" />
</form>
The form will add the parameter as part of the query string of the URL e.g. www.yoursite.com/Cauta/Componente?CodProiect=user+entered+value
Value of the Action is prepared at server side and sent to the browser so you cannot have the value at the server when it is a user input.
You can use jquery to change the URL at client side.
Also passing state in an PRG scenario is a common problem in ASP NET MVC. You can either:
Store it temporarily in session
Pass it as a parameter in URL
Use a form.
Form:
<form action="Componente/Cauta">
<input id="CodProiect" type="text" />
<input id="Cauta" type="submit" value="Cauta" />
</form>
Controller:
public ActionResult Cauta(string CodProiect)
{
//Do some stuff
}

Syntax may be outdated, but you get the point...
I have two submit buttons in one form. I want to call different actions in both buttons. Is there any way to accomplish this without using JavaScript.
Calling different actions is not possible without javascript. You could call the same controller action and inside this action determine which button was pressed using the name property:
<% using (Html.BeginForm()) { %>
<input type="submit" name="save" value="Save" />
<input type="submit" name="update" value="Update" />
<% } %>
and in your controller action:
[HttpPost]
public ActionResult Index(string save)
{
if (!string.IsNullOrEmpty(save))
{
// the save button was pressed
}
else
{
// the update button was pressed
}
return View();
}
Give the buttons different name attributes. Then in your view handler (or equivalent - sorry, not an ASP.NET MVC person), you can check if that button's name is in the HTTP response and act accordingly.
Only one of the submit button names should exist in the response.
Of course there is!
for example, we have following form:
<form>
<input name='customer_name' type='text'/>
<input name='update_user' type='submit' value='Update user info'/>
<input name='delete_user' type='submit' value='Delete user'/>
</form>
when server gets form request there exists only one parameter in the collection: either update_user or delete_user. depends on what user has pressed.
