I have these three checkboxes and a button that connects to another page. When that button is clicked, I want it to go to a page that is linked to the checkbox(es) that are checked.
<div data-role="content" data-theme="a">
<h2>Checkboxes</h2>
<div data-role="fieldcontain">
<input type = "checkbox" name = "nameOne" id = "checkBoxOne" checked = "checked" />
<label for = "checkBoxOne">Checkbox One</label>
<input type = "checkbox" name = "nameOne" id = "checkBoxTwo" />
<label for = "checkBoxTwo">Checkbox Two</label>
<input type = "checkbox" name = "nameOne" id = "checkBoxThree" />
<label for = "checkBoxThree">Checkbox Three</label>
<p>Continue</p>
</div>
</div>
Now when no checkboxes are checked, I want the href to link to '#linkToPage1', when the first checkbox is checked, I want it to link to '#linkToPage2', when the second is checked '#linkToPage3', when the third is checked '#linkToPage4', when first and second are checked '#linkToPage5', and so on.
So the '#linkToPageX' should change according to the checkbox(es) that are checked.
<input type="checkbox" checked="checked"/>
<input type="checkbox" checked="checked"/>
<input type="checkbox" checked="checked"/>
<input type="checkbox" checked="checked"/>
<input type="checkbox"/><br/>
<script>
document.write("The no of checked checkbox :"+$("input:checkbox[checked='checked']").length);
</script>
You can use the jquery selectors for find the no of checkbox checked
Recent browsers have querySelectorAll :
document.write("HTML5 : number of checked checkbox :" +
document.querySelectorAll ("input[type='checkbox'][checked='checked']").length);
Try it on your browser on http://jsfiddle.net/LwtvK/

if (document.querySelector("input[name='maca']")).getAttribute("checked")
<input type="radio" name="maca" id="maca1">
<input type="radio" name="maca" id="maca2">
I want to check if any one of the input type radio buttons with the same name is checked.
Select every radio button with that name with querySelectorAll, then use Array.some to check whether one of the items in the list is checked:
const radioButtons = document.querySelectorAll('input[name="maca"]')
const oneChecked = [...radioButtons].some(e => e.checked)
console.log(oneChecked)
<input type="radio" name="maca" id="maca1">
<input type="radio" name="maca" id="maca2" checked>
Alternatively, you can try selecting the checked radio button (with the :checked pseudo-class) and see if an element was selected:
if(document.querySelector('input[name="maca"]:checked')){
console.log('checked')
}
<input type="radio" name="maca" id="maca1">
<input type="radio" name="maca" id="maca2" checked>
<input type="radio" on-click="checkDefaultLanguage" id="checkbox" >
[[names(name)]]
this is my custom input field for radio and has dynamic values in it. I am trying to select one radio at a time and deselect from the others. but I cannot find any information for this. The one I have found are either with name attribute or having static input fields.
my JS
private checkDefaultLanguage() {
const checkboxes = <HTMLInputElement>this.querySelector('#checkbox');
checkboxes.addEventListener('click', () => {
if (checkboxes.checked) {
//what is should I do inside of it to make sure only one is selected at a time.
}
});
}
Just use name on the input, all input will get assigned to 1 group
<form>
<fieldset>
<legend>Select a maintenance drone</legend>
<div>
<input type="radio" id="huey" name="drone" checked />
<label for="huey">Huey</label>
</div>
<div>
<input type="radio" id="dewey" name="drone" />
<label for="dewey">Dewey</label>
</div>
<div>
<input type="radio" id="louie" name="drone" />
<label for="louie">Louie</label>
</div>
</fieldset>
</form>
tbh i dont fully understand what you are trying to do but you could pass the button you just clicked to the function
<input type="radio" on-click="checkDefaultLanguage(this)" id="checkbox" >
In your function you could just uncheck every box no matter if it's checked or not.
After this for-loop just check the one you passed to the function.
I cannot make the input name same or value same. The second and third inputs come from a loop using c# razor. I have 2 sets of radio inputs first one is one set and second and third are another set. Because the second and third have the same name, checking one makes the other unchecked. I want the same for all of them together so it would be like I have one set of 3 radio buttons. Like I said above I am not able to make the name or value same due to back-end data display issue. Here is my attempt below.
//first radio <br/>
<div class="radio">
<label>
<input id="dcenter-allradio" type="radio" value="0" />All
</label>
</div>
//this radio button is a loop <br>
<input type="radio" name="#Model.Facet.Key" value="#item.Key">tagitem.j
<div class="radio">
<label>
<input id="dcenter-listradio" type="radio" name="#Model.Facet.Key" value="#item.Key" />tagItem.Name
</label>
</div>
<script>
$(document).ready(function () {
if ($('#dcenter-listradio').prop("checked", true)) {
$('#dcenter-allradio').prop("checked", false);
}
if ($('#dcenter-allradio').prop("checked", true)) {
$('#dcenter-listradio').prop("checked", false);
}
});
</script>
If you can give them all the same class, then you can just use jQuery to detect when a change has occurred and then uncheck other items in the same class.
$(document).ready(function() {
var selector = ".groupTogether";
// or if you can't give same class, you could use "#unrelatedRadio, input[name='related']"
$(selector).change(function()
{
if(this.checked)
{
$(selector).not(this).prop('checked', false);
}
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<input id="unrelatedRadio" name="unrelated" type="radio" class="groupTogether">unrelated</input>
<input id="relatedA" name="related" type="radio" class="groupTogether">Related A</input>
<input id="relatedB" name="related" type="radio" class="groupTogether">Related B</input>
Or, if you can't give them the same class, just replace the selector with something that selects both sets (in my example, "#unrelatedRadio, input[name='related']")
let radios = document.querySelectorAll("input");
for (let i of radios){
i.name="same"
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
//first radio <br/>
<div class="radio">
<label>
<input id="dcenter-allradio" type="radio" value="0" />All
</label>
</div>
//this radio button is a loop <br>
<input type="radio" name="#Model.Facet.Key" value="#item.Key">tagitem.j
<div class="radio">
<label>
<input id="dcenter-listradio" type="radio" name="#Model.Facet.Key" value="#item.Key" />tagItem.Name
</label>
</div>
I am trying to test if checkbox is checked.
I have more inputs and they have different names.
I managed to select the input but I can't seem to check if it wa selected. If I add to the condition '= true' it is checked once I load the page. If I leave it just .checked it doesn't do anything
Have I selected the input right? Please note I want to select it by name rather than id or class
Why is it that once the page loads my condition for if statement doesn't work?
<input type="checkbox" name="name1">
<input type="checkbox" name="name2">
<input type="checkbox" name="name3">
<input type="checkbox" name="name4">
const firstInput = document.getElementsByName('name1');
if (firstInput[0].checked) {
console.log('checked');
}
You are selecting element with name "1" but don`t have element with such name.
If you want to select all inputs which name attribute starts with "name":
const firstInput = document.querySelectorAll('[name^=name]')
You need to add attribute to that input. Attach an onclick listener and invoke
getAttribute
setAttribute
to manipulate 'checked' attribute;
<input type="checkbox" onclick="myFunction()" name="name1">
<input type="checkbox" onclick="myFunction()" name="name2">
<input type="checkbox" onclick="myFunction()" name="name3">
<input type="checkbox" onclick="myFunction()" name="name4">
function myFunction() {
var $element = document.getElementsByName('name1')[0];
var checked = $element.getAttribute('checked') === 'true';
$element.setAttribute('checked', !checked);
console.log($element.getAttribute('checked'));
}
General issue: I cannot set a default radio button in my radio groups unless I remove the value attribute from the inputs.
Specifics: Each input has a value that is needed as it is being used by angular in other places in the app. So, I need to know how to set an input to default checked while retaining the values on the inputs. It has the same behavior if I try to add checked with jQuery instead of in HTML.
I have looked at several related questions including here. The specific issue is I need to have values and be able to set one input to checked as a default. The first input is set to checked, but it does not actually work unless I remove the value from that input.
Here is the HTML:
<div class="radio">
<label>
<input type="radio" ng-model="optionsRadios" id="new" value="new" checked>
New
</label>
<label>
<input type="radio" ng-model="optionsRadios" id="used" value="used">
Used
</label>
<label >
<input type="radio" ng-model="optionsRadios" id="broken" value="broken">
Broken
</label>
</div>
You have to use ng-checked="true" instead of checked
<input type="radio" ng-model="optionsRadios" id="new" value="new" ng-checked="true">
<!DOCTYPE html>
<html>
<script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.4.8/angular.min.js"></script>
<body ng-app="">
<p>My cars:</p>
<input type="radio" ng-model="all" value="Volvo" ng-checked="true">Volvo<br>
<input type="radio" ng-model="all" value="Ford">Ford<br>
<input type="radio" ng-model="all" value="Mercedes">Mercedes
</body>
</html>
If you have a group of radio button and you want to set radio button checked based on model, then radio button which has same
value and ng-model is checked automatically.
<input type="radio"
ng-model="optionsRadio" value="1" >
<input type="radio"
ng-model="optionsRadio" value="2" >
<input type="radio"
ng-model="optionsRadio" value="3" >
If the value of optionsRadio is "2" then second radio button will be selected automatically.
In Your Case:
When u r initiating the controller all u have to do is to assign a value to your model to keep atleast one radio button selected.
Controller part:
$scope.optionsRadio = "new";
Form part:
<input type="radio" ng-model="optionsRadio" value="new" >
<input type="radio" ng-model="optionsRadio" value="used" >
<input type="radio" ng-model="optionsRadio" value="broken" >
First radio button will be selected automatically.
Note:
If value doesn't work u can use ng-value.
