I would like to have 2 mutually exclusive fields.
One will be a FileField and other TextBoxField.
Is there a ready html form I can get my hands on to.
I have searched the web and couldnt find any.
Oh I am a little sorry..
I meant that I wanted to do this via Django Templates
You can make an onInput event listener and handle it using javascript, so that if the user types in one field it empties the other.
For example:
<form>
<label for="first">Fill This:</label>
<input type="text" name="first" id="first" oninput="run('first')"><br><br>
<label for="second">Or This:</label>
<input type="text" name="second" id="second" oninput="run('second')"><br><br>
<input type="submit" value="Submit">
</form>
<script>
function run(activeField) {
if (activeField == 'first') {
const second = document.querySelector('#second')
second.value = ''
} else {
const first = document.querySelector('#first')
first.value = ''
}
}
</script>
For Your textbox, you can use this:
<input type="text" name="name" placeholder="Please enter your name">
And for your files:
<input type="file" name="fileName">
But for file name it needs to be encrypted. HTML won't let you submit a form with a file. But you can override this in the form attr, like this:
<form action="dirToForm.py" method="POST" enctype="multipart/form-data"></form>
I am aiming to create a form to handle disabled JavaScript experience for a small component on my website. Currently I have the following form:
<form method="GET" action="https://mywebsite.com/somedirectory/">
<input type="radio" id="uid1" name="someParam" value="fruity" />
<label for="uid1">Fruit</label>
<input type="radio" id="uid2" name="someParam" value="veggie" />
<label for="uid2">Vegetable</label>
...other radio options
<input type="submit" value="Submit" />
</form>
Clicking on either of the radio options and then on the submit button will result in:
option 1: https://mywebsite.com/somedirectory/?someParam=fruity
option 2: https://mywebsite.com/somedirectory/?someParam=veggie
How can I add another value for each of the radio options? Say I would like to pass someOtherParam which is unique for each option and I would like to get this as output for my options:
option 1: https://mywebsite.com/somedirectory/?someParam=fruity&someOtherParam=apple
option 2: https://mywebsite.com/somedirectory/?someParam=veggie&someOtherParam=pepper
What I have tried is:
<input type="radio" id="uid1" name="someParam" value="fruity&someOtherParam=apple" />
<input type="radio" id="uid2" name="someParam" value="veggie&someOtherParam=pepper" />
However, the & symbol is converted to %26 inside the link and feels too hacky. Is there a better way to achieve this? Also, is there a way to make sure the Submit button is only enabled once a radio option is selected?
P.S. I am aiming for pure HTML experience with no Javascript involved. Is that possible?
I'm pretty sure this is not posible in modern browsers without the use of JS. Maybe on old browsers you could do some tricks with CSS and display:none because it used to not send fields with display:none, but nowdays that is not an option.
If you can allow Javascript, you can add a data attribute to each radio option and use it to populate an extra hidden input on change.
document.querySelectorAll('input[type=radio][name="someParam"]')
.forEach(radio => radio.addEventListener('change', (event) =>
document.getElementById('someOtherParam').value = event.target.dataset.extraValue
));
<form method="GET" action="https://mywebsite.com/somedirectory/">
<input type="radio" id="uid1" name="someParam" value="fruity" data-extra-value="apple" />
<label for="uid1">Fruit</label>
<input type="radio" id="uid2" name="someParam" value="veggie" data-extra-value="pepper" />
<label for="uid2">Vegetable</label>
<input type="hidden" id="someOtherParam" name="someOtherParam">
<input type="submit" value="Submit" />
</form>
To add another radio group independent from others, use a distinct name property. For example, to add a second parameter called someOtherParam to the request, create a radio group with name="someOtherParam":
<input type="radio" id="uid3" name="someOtherParam" value="apple" />
<input type="radio" id="uid4" name="someOtherParam" value="pepper" />
And add their correspondent labels.
Also, is there a way to make sure the Submit button is only enabled once a radio option is selected?
You can add the required attribute to prevent the browser to send the form before all the inputs have a value.
Without javascript, what you're describing cannot be done.
What you could do, as other posters have suggested is:
Create radio buttons for the list of options that are possible for each category (fruits / vegetables etc)
<input type="radio" id="uid3" name="someOtherParam" value="apple" />
<input type="radio" id="uid4" name="someOtherParam" value="pepper" />
When processing the input on your server side code, check if you have received a value or not. If not, you can choose a default option (apple or whatever). On your page you can mention what the default option would be in case they don't make a selection.
You could make some of the input required as suggested, but you would still have to make check on the server side that the input has been received, since the required attribute is just a suggestion to users browsers - it won't stop a malicious persons from making a request without that parameter by running a script etc.
To submit extra information to the server, you can use a hidden input type and change value as per your needs using javascript.
HTML code
<form method="GET" action="">
<input type="radio" id="uid1" name="someParam" value="fruity" />
<label for="uid1">Fruit</label>
<input type="radio" id="uid2" name="someParam" value="veggie" />
<label for="uid2">Vegetable</label>
<input type="hidden" id="uid3" name="someOtherParam" value="" readonly required />
<input type="submit" value="Submit" onclick="onSubmit()" />
</form>
Javascript code
function onSubmit () {
let fruityRadio = document.getElementById( 'uid1' );
let veggieRadio = document.getElementById( 'uid2' );
if ( fruityRadio.checked ) {
document.getElementById( 'uid3' ).value = 'apple';
} else if ( veggieRadio.checked ) {
document.getElementById( 'uid3' ).value = 'pepper';
}
}
Easy, double up the value with a deliminator between every extra value:
HTML
<div>
<label for="uid1">
<input id="uid1" name="fruit1" type="radio" value="apple:orange" />
Fruit, Apple + Orange
</label>
</div>
<div>
<label for="uid2">
<input id="uid2" name="fruit1" type="radio" value="apple:cherry:lime" />
Fruit, Apple + Cherry + Lime
</label>
</div>
node.js
I'm not sure how node.js handles what PHP refers simply as $_POST['name_attribute_value_here'] though I do know you simply want to use .split(':') to get the two or more values from that single form. If you want more options per radio button just append a deliminator (it doesn't have to be :) between each value.
Both of those radio options have the name "fruit1" so the user can't choose both.
No JavaScript is necessary.
A minor adaptation on the server.
Extra values will obviously not appear to the server if the user doesn't select that radio form field.
Arrays
If you want to set your own key/values then just add a second deliminator:
<input name="fruit1" value="fruit:apple,fruit:lime,color:purple,planet:Earth" />
Then at the server use [whatever].split(',') to get the pairs and iterate in a loop to get each key/value. You could create an entire crazy multi-dimensional array if you really wanted to.
I hope this helps, feel free to comment if you need any further clarification.
Generate form:
const data = [
{ name: 'apple', type:"fruity" },
{ name: 'pepper', type:"veggie"}
]
const form = document.querySelector('form');
const uid = document.querySelector('#uid')
createOptions(data);
function createOptions(data){
data.forEach((e, index) => {
const f = document.createDocumentFragment();
const l = document.createElement('label');
const i = document.createElement('input');
l.setAttribute('for', `uid${index+1}`);
l.textContent=e.name;
i.setAttribute('type', `radio`);
i.setAttribute('for', `uid${index+1}`);
i.setAttribute('name', 'someOtherParam');
i.setAttribute('value', e.name);
i.dataset.otype = e.type;
f.appendChild(l);
f.appendChild(i);
form.insertBefore(f, uid);
i.addEventListener('change', onselectChange, false);
})
}
function onselectChange(event) {
uid.value = event.target.dataset.otype;
}
<form method="GET" action="https://mywebsite.com/somedirectory/">
<input type="text" id="uid" name="someParam"
style="width:0; visibility: hidden;">
<input type="submit" value="Submit" />
</form>
I can't think another way of doing this using less code, the following achieves your desired result:
<form name="form" method="GET" action="">
<input type="radio" id="uid1" name="someParam" required value="fruity" onchange="document.form.someOtherParam.value = 'apple'" />
<label for="uid1">Fruit</label>
<input type="radio" id="uid2" name="someParam" required value="veggie" onchange="document.form.someOtherParam.value = 'pepper'" />
<label for="uid2">Vegetable</label>
<input type="hidden" name="someOtherParam" value=""/>
<input type="submit" value="Submit"/>
</form>
There's only 3 changes to your example:
Add a name to the form, then add inline attributes required and onchange to each radio, finally add an input[type=hidden] to include the extra param. The first change is meant so you'll not need document.getElementById later, the second so the form won't be empty submitted and also update the hidden desired value.
I have this input:
<input name="giftwrap" type="checkbox"/>
However, when the form is submitted and the checkbox has not been checked, I get a null rather than a false. I want a false to be submitted.
I'm feeling if I give the input a default value of unchecked it'll return false rather than null as if I tick and then untick the input I get false.
So how do I set the input as checked, and how do I set the input as unchecked?
$(function() {
$('input[name=giftwrap]').on('change', function() {
$(this).next().text(this.value = this.checked);//<-- note its assignment
}).trigger('change');//<-- trigger on page load
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input name="giftwrap" type="checkbox" /><span></span>
You can add a checked attribute:
<input name="giftwrap" type="checkbox" checked/>
Or maybe you want something like this:
<form>
<input type='hidden' value='0' name='selfdestruct'>
<input type='checkbox' value='1' name='selfdestruct'>
</form>
Details: Post the checkboxes that are unchecked
(Read the comments as well.)
Consider a form in Html:
<form action="demo_form.asp" method="get">
<div class="form-group" style="margin-top:7px;">
<label class=".... </label>
<input type="text" name="prefersite1" placeholder="http://www.website.com">
<input type="text" name="prefersite2" cla....;">
<input type="text" name="prefersite3" cl....">
<input type="text" name="prefersite4" c....">
<input type="text" name="prefersite5" cla....">
</div>
On using a 'submit' type button, is there a way to get appended prefersite_list[] or comma separated string in the url
The button I used is just:
<button type="submit">
Submit
</button>
I am working on django platform and use this url to extract variables by request.GET.get method in python. Is there a way to change name=prefersite[0], [1] etc so that I will get a single long string.
Instead of /?prefersite1=&prefersite2=&prefersite3=.. , I need a single /?prefersite=.
Using prefersite[] as name seems to be working for post forms, but I need to use get forms.
I have check box at UI side on which i want to bind data coming from web service in form of jason
Html code:
<label class="checkbox-inline nopaddingleft" for="radio1">
<input name="radio1" type="checkbox" id="radio1"
class="checkbox-inline margin-right-five"
value="name" checked={{insuredProfile.isScrubbed}} />Scrub
</label>
The value i want to bind is:{{insuredProfile.isScrubbed}} it will be true or false
Thanks in advance
In your view use ngChecked.
In your controller you'll need to have something like:
$scope.insuredProfile = { isScrubbed: true };
You have to use ng-model for the checkbox input.
ng-model="insuredProfile.isScrubbed"
