I'm looking for a solution to generate multiple forms on one page, that contain the same checkboxes and fields. For now, when I create those forms, even if I use different form names, all checkboxes with the same name get checked at the same time.
What I am trying to do is the following. I do have an events-list. Every event should have a form attached. Every form has some text and some checkboxes. But when I'm trying to check some boxes in my second form, it jumps to the first one (because of the same name of the checkbox).
<form method="post" name="form1">
<input type="checkbox" name="checkbox1" />
<input type="checkbox" name="checkbox2" />
</form>
<form method="post" name="form2">
<input type="checkbox" name="checkbox1" />
<input type="checkbox" name="checkbox2" />
</form>
Is there a way to get this working? Or do I have to use unique checkbox names, even if the formnames are unique? Which would make it more complex when I have a variable count of forms / events.
You can dynamically bind form elements i.e checkboxes. Don't include it in HTML code. This can be done with Jquery $.html() function to bind checkboxes to forms at runtime.
I guess this happens because form1 overrides form2 elements due to same names and id of checkboxes.
Or Try to use 4 different id of all checkboxes, and different id's of form names.
Hope it may work.
Happy Coding!

I have a form that has a save button in it. I also have 10 checkboxes that I need to require the user to check at least one of them, then another set of 6 checkboxes that I need the user to check at least one of them. Is there a way to have a message pop up when the user tries to save the record without having made a selection in both of these areas?
Yes, you need a validated form with jQuery.
First thing is that your HTML will need a checkbox array like:
<input type="checkbox" name='cb[]' value='cb1'/>
<input type="checkbox" name='cb[]' value='cb2'/>
<input type="checkbox" name='cb[]' value='cb3'/>
<input type="checkbox" name='cb[]' value='cb4'/>
<input type="checkbox" name='cb[]' value='cb5'/>
if(jQuery('input[name=cb]:checked').length==0) {
console.log('Please check at least one checkbox');
}
Something like that...For your other checkbox group, use a different name like name="cb2[]" and jQuery would be:
if(jQuery('input[name=cb2]:checked').length==0) {
console.log('Please check at least one checkbox');
}
I hope this helps.
I want to post checkbox values to server using html. But my code retrieves nothing. Please help.
<form action="Default2.aspx" method="post" >
<input type="checkbox" name="attempt" value="101"> I'st attempt<br>
<input type="checkbox" name="attempt" value="102" checked> 2nd attempt<br>
<input type="submit" value="Submit">
</form>
They need ID's so they can be referred to and if this is a Web Forms website you need to also have the attribute runat="server" for both of them otherwise you won't be able to access them.
ASP.NET Page already has form element in the root, and you don't have insert it by self. If you use native HTML element in your ASP.NET page or control, you can get their values by using Request Object. See simple example here How-get-input-text-value-server-side-c.aspx
In plain HTML forms, checkbox input controls don't get included in the submission at all if the user left them unchecked. See this question: Does <input type="checkbox" /> only post data if it's checked?
I have several sections in my page that I need to include under the same form tag, but doing so breaks the HTML. For example:
<div>
<form name="firstform">
<input type="text" name="input1" />
<input type="text" name="input2" />
<input type="text" name="input3" />
</div>
<p>bla bla</p>
<div>
<form name="secondform">
<input type="text" name="one" />
</form>
<input type="text" name="input4">
</form>
So basically I want to submit the form firstform but in a way that will include input4 but without submitting secondform?
EDIT:
I have a pretty long page with a lot of inputs, in the middle of the page I have a different form that is used to allow file upload which I want to keep where it is in the page, however, after that section I have a continuation of the first form. so I have the first form, then another form with the file upload and then the rest of the first form.
If you want to have multiple forms, use one form tag with multiple submit buttons. Give to the buttons name and value and its time a user submit the form, chech in the back end which button has been pushed.
You could simply add an html button with an onClick event that calls a function to mimic a nested form. If the second form's onSubmit function is pure javaScript this could be a quick cut/paste. If your second form is communicating with a server you'll have to jump into some AJAX.
I have an input type of radio, when using Angular to wire up the backend. However, it is currently allowing multiple selections, which is completely odd since radio is by default single selection.
<div ng-repeat="s in survey">
<input type="radio" data-ng-model="s.isSelected">{{s.id}}
</div>
Has anyone run into this, or notice something I am missing?
Assign a name attribute with the same value to all radiobuttons in the same group.
ex:
<input type="radio" name="group1" data-ng-model="s.isSelected">{{s.id}}
I'm trying to program a dynamic form, so I can't use the normal form tags and stuff. I use normal buttons, JQuery, and AJAX calls to simulate a traditional form. However, I can't figure out how to do radio buttons. Any help?
EDIT: Yeah, I suppose I should have been more specific. I tried doing
<input type="radio" />
and stuff, but:
it lets me select more than one button at a time (which kind of defeats the point of radio buttons)
it won't let me deselect a button after it's pressed!
EDIT 2: The reason I'm not using form tags is that I need multiple submit buttons as well, and the only solution I found to that dilemma was to not use form tags.
Why can't you use the form tag? There is nothing stopping you from doing so. But if you don't want to use the form tag, why not:
<input type='radio' name='test' value='1' checked>
<input type='radio' name='test' value='2'>
<input type='radio' name='test' value='3'>
<input type='radio' name='test' value='4'>
Works fine for me. Demo
Edit:
1: You need to specify a name for the radio group, otherwise each input is considered its own group. Hence why you can select more than one button at a time when using <input type="radio" />. Look at my code above. The radio group is 'test'.
2: Radio buttons are suppose to have a default value. When you create a radio group you should be specifying a default value with the checked attribute. A consequence of this is that you can't deselect a radio button. You can either choose a different value or stick with the default. If you want to be able to deselect, then consider using checkboxes instead. I've updated the example code to reflect this.
If you are able to select more than one radio button, its sounds like your name attributes are not matching. What you want to end up with is something like the following:
<input type="radio" name="group-1" value="something-unique">
<input type="radio" name="group-1" value="something-else-unique">
<input type="radio" name="group-1" value="another-unique-something">
<input type="radio" name="group-2" value="something-unique">
<input type="radio" name="group-2" value="something-else-unique">
<input type="radio" name="group-2" value="another-unique-something">
Note that the name attribute is the same for the group of options, which means that the selections will replace each other.
Also, I haven't had any issues not wrapping radios in form tags, when using them purely with javascript, however if you want to do any html post stuff, I would expect that they are required.
You can try this:
HTML
<div>
<ul>
<li><input type="radio" name="radio" value="value1" checked>Radio Button1</input></li>
<li><input type="radio" name="radio" value="value1">Radio Button2</input></li>
<li><input type="radio" name="radio" value="value1">Radio Button3</input></li>
</ul>
</div>
DEMO
There should not be an input element without a form element. You are not going to get the HTML to respond the way you want it to if you do not use it correctly. Multiple submit buttons would indicate the need for multiple forms.
If, for whatever reason, that does not work, perhaps you should reconsider the format through which you are asking the user to submit information.
