i would like to know how to disable/hide all the buttons once user clicks on any of the buttons. I am only allowed to use c# or html. I have found solutions in Javascript but i cannot use it. (i did not upload my razor c# code due to lack of space)
I am creating a program that allows user to vote for any one of the candidates. Once user has clicked and chosen on one candidate, the voting result will be displayed and user should not be allowed to vote again.
<!DOCTYPE html>

<form id="form1" method="post">

<td>John</td>
<td><input id="John" name="submit" type="submit" value="Vote John" /></td>

<td>Bryan</td>
<td><input id="Bryan" name="submit" type="submit" value="Vote Bryan" /></td>
</tr>
<tr>
<td>Jack</td>
<td><input id="Jack" name="submit" type="submit" value="Vote Jack" /></td>
</tr>
</table>
</div>
<div>
#if (result != "")
{
<p>#result</p>
}
<!--Ensure that user has voted before showing the vote results-->
#if (voteCheck == true)
{
<p>Total Votes: #Session["totalVotes"]</p> <!--using session allows values to be kept even after button click-->
<p> Harry: #Session["Harry"]</p>
<p> John: #Session["John"]</p>
<p> Bryan: #Session["Bryan"]</p>
<p> Jack: #Session["Jack"]</p>
}
</div>

You need an action attribute to the form action="youraction/controller here"
And in youraction you write some C# code return list of display value ("none" or "")
And in cshtml you add style="display:#display"
<input id="Harry" name="submit" type="submit" style="display:#display" value="Vote Harry" />
You could simply add a Ternary operator that check the session object and sets the disabled property accordingly.
<input id="Harry" #(Session["Harry"] != null ? "disabled" : "") name="submit" type="submit" value="Vote Harry" />
I have a little question... I dont know whats happening but submit event is working because when I click "ingresar" submit button, it sends all the data.
But when I press enter nothing happens.
I think the problem is that i have the form inside of a table....
Am I wrong? I think the problem is here because,as I said, when i press Ingresar submit button it sends the data.
Thx for your help! :)

Your HTML code seems to be okay, so there must be something in your browser or in the PHP code: the "enter submit" doesn't work when the submit button is not present in the form, otherwise, it should work.
You can see if it is working using inspector tool, press f12 to open it in your browser, change to networking tab, and try to click on submit button if something happens its ok.
I notice that in your form you are not using action form atribute, try it like this example: http://www.w3schools.com/html/html_forms.asp
I have a single table that is generated dynamically by looping through a result set and creating rows. For each row, I need to include 2 checkboxes. Checkbox A on each row needs to correspond to form A, and checkbox B to form B.
I know this isn't valid, but the below pseudocode is essentially what I want. I know that in HTML5 I can specify which form an input element belongs to, but my users will primarily be using IE8, which, as far as I can tell, doesn't support this feature.
<form name="formA">
<form name="formB">
<table>
<tr>
<th>
<th>
<th>
</tr>
LOOP
<tr>
<td><input type="checkbox" name="chkA" value="1"></td>
<td>Something</td>
<td><input type="checkbox" name="chkB" value="1"></td>
</tr>
END LOOP
</table>
<input type="submit" /> //formA
<input type="submit" /> //formB
</form> //formA
</form> //formB
Any ideas on how I can accomplish this? I suppose one way would be to use a single form and change the action depending on which submit button is clicked, but I want to see if anyone else has any ideas before I do that.
Thanks,
Tom
Probably the best way is to just make it all in one form and act differently later according to the options selected.
For example
<form action="doStuff.php" method="post">
<table>
<tr>
<th></th>
<th></th>
</tr>
<!-- LOOP -->
<tr>
<td><input type="checkbox" name="chkA" value="1"></td>
<td><input type="checkbox" name="chkB" value="1"></td>
</tr>
<!-- END LOOP -->
</table>
<div>
<input type="submit" name="submit" />
</div>
</form>
doStuff.php
if (isset( $_POST["chkA"] ) ){
// Checkbox A is checked.
}
if (isset( $_POST["chkB"] ) ){
// Checkbox B is checked.
}
I have done something like this.
<html>
<head>
<script type="text/javascript">
<!--
function toggleTB(what){
if(what.checked){document.theForm.theTB.disabled=1}
else{document.theForm.theTB.disabled=0}}
//-->
</script>
</head>
<body>
<form name="theForm">
<input type="checkbox" name="theCB" onClick="toggleTB(this)">Toggle The Text Box<br>
<input type="text" name="theTB" value="asdf">
</form>
</body>
</html>
But this is only used for one time.i need this function repeatedly in another rows also so how can i used this function for multiple times.
My form goes like this:
<tr>
<td style="border-top:none; text-decoration:underline;" >Specific operations/procedures</td>
<td>
<input type="checkbox" name="sd3[]" value="mfi_nam9" />Other(please specify):
<input type="text" name="mfi_nam9" class="text required" id="mfi_name"
</td>
</tr>
<tr>
<td style="border-top:none; text-decoration:underline;" >General principles/strategies</td>
<td>
<input type="checkbox" name="sd2[]" value="mfi_nam8" />Other(please specify):
<input type="text" name="mfi_nam8" class="text required" id="mfi_name"
</td>
</tr>
i will be waiting for ur response and i am very thankful to u guys for helping me previously and hope u will help me this time too.
Read this article
i would prefer jQuery
Here is DEMO
Another DEMO
We can take the code and do the modifications like
1. Javascript modifications :
function toggleTB(what,elid)
{
if(what.checked)
{
document.getElementById(elid).disabled=1
}
else
{
document.getElementById(elid).disabled=0
}
}
2. Checkbox HTML code modifications
<input type="checkbox" name="sd3[]" value="mfi_nam9" onClick="toggleTB(this,'mfi_name1')" />Other(please specify):
<input type="text" name="mfi_nam9" class="text required" id="mfi_name1" />
Note that we have used the ID's to be varying for each of the textboxes which can be generated even when you are generating these textboxes from the php codes.
Add onclick to each of the checkbox
<input type="checkbox" name="sd2[]" value="mfi_nam8" onClick="toggleTB(this)" />Other(please specify):
and declare toggleTB as
function toggleTB(what){
what.form.elements[what.value].disabled = what.checked;
}
Java Script modification :
function toggleTB(what){
var theTB = document.getElementById(what.value);
if(what.checked){theTB.disabled=1}
else{theTB.disabled=0}
}
HTML Modification :
<table>
<tr>
<td style="border-top:none; text-decoration:underline;" >Specific operations/procedures</td>
<td>
<input type="checkbox" name="sd3[]" onClick="toggleTB(this)" value="mfi_nam9" />Other(please specify):
<input type="text" name="mfi_nam9" id="mfi_nam9" class="text required" />
</td>
</tr>
<tr>
<td style="border-top:none; text-decoration:underline;" >General principles/strategies</td>
<td>
<input type="checkbox" name="sd2[]" onClick="toggleTB(this)" value="mfi_nam8" />Other(please specify):
<input type="text" name="mfi_nam8" id="mfi_nam8" class="text required" />
</td>
</tr>
</table>
Note: Here I have used ID rather than NAME to verify the form input box element.
I think this doesn't make sense to disable the TEXT BOX on checked event of the related CHECK BOX. You maybe want to enable the TEXT BOX whenever some one checked the check box to specify some other thing, I am not sure what you want to do with this.
If you want to do like what I guess, just change the JAVA SCRIPT lines as bellow -
if(what.checked){theTB.disabled=0} // have placed 0 in place of 1
else{theTB.disabled=1} // have placed 1 in place of 0
}
HTML INPUT-BOX as bellow -
OR if you think to toggle (enable/disable) the checkbox, this is not possible cause you know after disable an element the click event will not do action on the element so how it will be disable :)
I can best describe this as follows:
I want this (entire table in editmode and save button in every row).
<table>
<tr>
<td>Id</td>
<td>Name</td>
<td>Description</td>
<td> </td>
</tr>
<tr>
<td><input type="hidden" name="id" value="1" /></td>
<td><input type="text" name="name" value="Name" /></td>
<td><input type="text" name="description" value="Description" /></td>
<td><input type="submit" value="Save" /></td>
</tr>
<tr>
<td><input type="hidden" name="id" value="2" /></td>
<td><input type="text" name="name" value="Name2" /></td>
<td><input type="text" name="description" value="Description2" /></td>
<td><input type="submit" value="Save" /></td>
</tr>
<!-- and more rows here ... -->
</table>
Where should I put the <form> tags?
It's worth mentioning that this is possible in HTML5, using the "form" attribute for input elements:
<table>
<tr>
<td>Id</td>
<td>Name</td>
<td>Description</td>
<td> </td>
</tr>
<tr>
<td><form id="form1"><input type="hidden" name="id" value="1" /></form></td>
<td><input form="form1" type="text" name="name" value="Name" /></td>
<td><input form="form1" type="text" name="description" value="Description" /></td>
<td><input form="form1" type="submit" value="Save" /></td>
</tr>
<tr>
<td><form id="form2"><input type="hidden" name="id" value="1" /></form></td>
<td><input form="form2" type="text" name="name" value="Name" /></td>
<td><input form="form2" type="text" name="description" value="Description" /></td>
<td><input form="form2" type="submit" value="Save" /></td>
</tr>
</table>
While clean in its lack of JS and use of original elements, unfortunately this isn't working in IE10.
I had a similar question and this answer in question HTML: table of forms? solved it for me. (Not sure if it is XHTML, but it works in an HTML5 browser.)
You can use css to give table layout to other elements.
.table { display: table; }
.table>* { display: table-row; }
.table>*>* { display: table-cell; }
Then you use the following valid html.
<div class="table">
<form>
<div>snake<input type="hidden" name="cartitem" value="55"></div>
<div><input name="count" value="4" /></div>
</form>
</div>
You can't. Your only option is to divide this into multiple tables and put the form tag outside of it. You could end up nesting your tables, but this is not recommended:
<table>
<tr><td><form>
<table><tr><td>id</td><td>name</td>...</tr></table>
</form></td></tr>
</table>
I would remove the tables entirely and replace it with styled html elements like divs and spans.
I wrote the below over ten years ago, when the world was a different place. These days I know of many ways to crack this particular nut, but a quick and dirty solution that will validate is to do much the same but use CSS tables for layout, not a regular HTML table.
I'd say you can, although it doesn't validate and Firefox will re-arrange the code (so what you see in 'View generated source' when using Web Developer may well surprise). I'm no expert, but putting
<form action="someexecpage.php" method="post">
just ahead of the
<tr>
and then using
</tr></form>
at the end of the row certainly gives the functionality (tested in Firefox, Chrome and IE7-9). Working for me, even if the number of validation errors it produced was a new personal best/worst! No problems seen as a consequence, and I have a fairly heavily styled table. I guess you may have a dynamically produced table, as I do, which is why parsing the table rows is a bit non-obvious for us mortals. So basically, open the form at the beginning of the row and close it just after the end of the row.
The answer of #wmantly is basicly 'the same' as I would go for at this moment.
Don't use <form> tags at all and prevent 'inappropiate' tag nesting.
Use javascript (in this case jQuery) to do the posting of the data, mostly you will do it with javascript, because only one row had to be updated and feedback must be given without refreshing the whole page (if refreshing the whole page, it's no use to go through all these trobules to only post a single row).
I attach a click handler to a 'update' anchor at each row, that will trigger the collection and 'submit' of the fields on the same row. With an optional data-action attribute on the anchor tag the target url of the POST can be specified.
Example html
<table>
<tbody>
<tr>
<td><input type="hidden" name="id" value="row1"/><input name="textfield" type="text" value="input1" /></td>
<td><select name="selectfield">
<option selected value="select1-option1">select1-option1</option>
<option value="select1-option2">select1-option2</option>
<option value="select1-option3">select1-option3</option>
</select></td>
<td><a class="submit" href="#" data-action="/exampleurl">Update</a></td>
</tr>
<tr>
<td><input type="hidden" name="id" value="row2"/><input name="textfield" type="text" value="input2" /></td>
<td><select name="selectfield">
<option selected value="select2-option1">select2-option1</option>
<option value="select2-option2">select2-option2</option>
<option value="select2-option3">select2-option3</option>
</select></td>
<td><a class="submit" href="#" data-action="/different-url">Update</a></td>
</tr>
<tr>
<td><input type="hidden" name="id" value="row3"/><input name="textfield" type="text" value="input3" /></td>
<td><select name="selectfield">
<option selected value="select3-option1">select3-option1</option>
<option value="select3-option2">select3-option2</option>
<option value="select3-option3">select3-option3</option>
</select></td>
<td><a class="submit" href="#">Update</a></td>
</tr>
</tbody>
</table>
Example script
$(document).ready(function(){
$(".submit").on("click", function(event){
event.preventDefault();
var url = ($(this).data("action") === "undefined" ? "/" : $(this).data("action"));
var row = $(this).parents("tr").first();
var data = row.find("input, select, radio").serialize();
$.post(url, data, function(result){ console.log(result); });
});
});
A JSFIddle
You just have to put the <form ... > tag before the <table> tag and the </form> at the end.
Hopte it helps.
In fact I have the problem with a form on each row of a table, with javascript (actually jquery) :
like Lothre1 said, "some browsers in the process of rendering will close form tag right after the declaration leaving inputs outside of the element"
which makes my input fields OUTSIDE the form, therefore I can't access the children of my form through the DOM with JAVASCRIPT..
typically, the following JQUERY code won't work :
$('#id_form :input').each(function(){/*action*/});
// this is supposed to select all inputS
// within the form that has an id ='id_form'
BUT the above exemple doesn't work with the rendered HTML :
<table>
<form id="id_form"></form>
<tr id="tr_id">
<td><input type="text"/></td>
<td><input type="submit"/></td>
</tr>
</table>
I'm still looking for a clean solution (though using the TR 'id' parameter to walk the DOM would fix this specific problem)
dirty solution would be (for jquery):
$('#tr_id :input').each(function(){/*action*/});
// this will select all the inputS
// fields within the TR with the id='tr_id'
the above exemple will work, but it's not really "clean", because it refers to the TR instead of the FORM, AND it requires AJAX ...
EDIT : complete process with jquery/ajax would be :
//init data string
// the dummy init value (1=1)is just here
// to avoid dealing with trailing &
// and should not be implemented
// (though it works)
var data_str = '1=1';
// for each input in the TR
$('#tr_id :input').each(function(){
//retrieve field name and value from the DOM
var field = $(this).attr('name');
var value = $(this).val();
//iterate the string to pass the datas
// so in the end it will render s/g like
// "1=1&field1_name=value1&field2_name=value2"...
data_str += '&' + field + '=' + value;
});
//Sendind fields datawith ajax
// to be treated
$.ajax({
type:"POST",
url: "target_for_the_form_treatment",
data:data_string,
success:function(msg){
/*actions on success of the request*/
});
});
this way, the "target_for_the_form_treatment" should receive POST data as if a form was sent to him (appart from the post[1] = 1, but to implement this solution i would recommand dealing with the trailing '&' of the data_str instead).
still I don't like this solution, but I'm forced to use TABLE structure because of the dataTables jquery plugin...
Im late to the party, but this worked great for me and the code should explain itself;
<script type="text/javascript">
function formAJAX(btn){
var $form = $(btn).closest('[action]');
var str = $form.find('[name]').serialize();
$.post($form.attr('action'), str, function(data){
//do stuff
});
}
<script>
HTML:
<tr action="scriptURL.php">
<td>
Field 1:<input type="text" name="field1"/>
</td>
<td>
Field 2:<input type="text" name="field2" />
</td>
<td><button type="button" onclick="formAJAX(this)">Update</button></td>
</tr>
If you try to add a form warping a tr element like this
<table>
<form>
<tr>
<td><input type="text"/></td>
<td><input type="submit"/></td>
</tr>
</form>
</table>
some browsers in the process of rendering will close form tag right after the declaration leaving inputs outside of the element
something like this
<table>
<form></form>
<tr>
<td><input type="text"/></td>
<td><input type="submit"/></td>
</tr>
</table>
This issue is still valid for warping multiple table cells
As stereoscott said above, nesting tables are a possible solution which is not recommended.
Avoid using tables.
