I want to have a checked checkbox behave as an unchecked checkbox, and an unchecked checkbox behave as a checked checkbox. How can this be accomplished?
Context: In my template is a for loop that creates a checkbox for each filter condition. I want to show the user that the initial setting has all checkboxes checked, and they can uncheck them to exclude certain categories. The backend uses exclude statements, therefore it's necessary to invert the checkboxes.
Try the checked attribute
<input type="checkbox" name="vehicle" value="Car" checked> I have a car<br>

I have 2 radio button, (input type radio),i used "checked" on the second, now, if i want to check the first radio button i need to click twice, how di i fix it ??
<label>YES</label> <input type={'radio'} name={'license'}/><br />
<label>NO</label> <input type={'radio'} name={'license'} checked={'checked'}/>
You are using uncontrolled inputs, so the React rendering cycle is interfering with the user modified state of the DOM.
If you continue using uncontrolled inputs, use defaultChecked and not checked. (See default values.)
Controlled components are recommended in most cases though.
I have few checkboxes on my page, with few of them checked by default.
Through my code, I need to handle unchecking of all text boxes on the page and then proceed.
The problem is the checkboxes (both checked and un-checked) have exactly the same HTML / DOM structure with same attributes / values except for the "::after" appearing when the checkbox is checked.
How do I write a locator to find out if the element is checked or unchecked, and then proceed to uncheck it.
<!-- When checkbox is unchecked -->
<label class="someclasslabel" on-click="[[event]]">
<span>Male</span>
<input type="checkbox" data-bind="checked: $properties.value">
<span class="checkbox"></span>
</label>
<!-- When checkbox is checked -->
<label class="someclasslabel" on-click="[[event]]">
<span>Male</span>
<input type="checkbox" data-bind="checked: $properties.value">
<span class="checkbox">
::after
</span>
</label>
I want a locator, so that I can get attribute if its checked or unchecked, and then uncheck it if already checked.
You could try executing some Javascript on your checkbox element to get the value.
after_value = driver.execute_script
("return window.getComputedStyle(document.querySelector('.someclasslabel'),':after')
.getPropertyValue('content');")
This is a bit of a hack, but worth a try.
After getting all the checkbox elements (with the same selector) no matter if they are checked or not, you can then iterate through them with a loop, and check if they are checked with the selected method. (C# reference here https://seleniumhq.github.io/selenium/docs/api/dotnet/ for RemoteWebElement.Selected Property).
If .selected == true -》click; if not selected, do nothing;
Is there a way in html markup to have a checkbox greyed-out and checked?
I wan't to keep the checkbox styled depending on the browser, so not alter it too much with css.
I'm trying to have a row of 4 checkboxes. One is checked and blue by default, the other three are disabled and greyed out. When you either:
- click on the first one the other three become actively blue again
- or when you click on one of the three disabled ones the first one becomes inactive
<input type="checkbox" checked disabled />
<input type="checkbox" checked onclick="return false"/>
OR
<input type="checkbox" checked disabled />
The disabled will gray it out, the first example won't
Add disabled="disabled" to the end of the input tag. If you wanted the checkbox to be ticked on load add checked instead.
I have a form that has a list of radio buttons and one checkbox that represents a special "button". All form elements have the same name:
<input type="checkbox" name="channel" id="prv" value="ch1">
<input type="radio" name="channel" value="ch2">
<input type="radio" name="channel" value="ch3">
<input type="radio" name="channel" value="ch4">
My idea is that once the checkbox is checked, all the other radio buttons are disabled (which works quite well with jQuery). If the checkbox is unchecked, the user can select some channel with the radio buttons.
But when I submit the form, it doesn't work at all.
$('#prv').change(function () {
if (this.checked) {
$(".fc_exp input").attr('disabled',true); <--RADIO BUTTONS
$(".fc_exp input").removeAttr('checked'); <--RADIO BUTTONS
} else {
$(".fc_exp input").attr('disabled',false); <--RADIO BUTTONS
$('.fc_exp #ch1, .fc_exp label[for="#ch1"]').prop('checked',true); <--DEFAULT RADIO BUTTON: CHECKED
}
})
Now my question is: Is there any best practice for this?
Thanks a lot and merry xmas!
I would suggest using four radio buttons - first one with option "No channel" or whatever option you need here - instead of the checkbox.
If you really need checkbox and radios - checkbox should be named differently in the form - but this will require additional code on server side to handle it properly.
I'm really new to HTML, but I can't find anywhere how to return the variable from a check box. I've figured out how to get variables from forms and inputs, but I don't know how to get them from check boxes. Basically, I want a check box that if checked, will return the value yes. If not checked, it doesn't have to return a value, but no would be nice.
When submitting a form, if a checkbox is checked, it will be included in the values collection submitted to the server. If not checked, it will be omitted (as if that checkbox did not exist).
In JavaScript, you can find out whether the checkbox is checked by the checked property:
//returns true or false
var isChecked = document.getElementById('id_of_checkbox').checked;
In ASP.NET, the CheckBox control has a boolean property Checked.
Assign something to the value attribute. You should get the value of the checked box, if there is one in the form values on postback. Note that I've made it a radio input in the case where you want yes or no. For a radio you need to assign the same name, but different ids (if you assign an id at all). You'd want to use checkboxes in the case where you can have more than one value selected or only care to get the value when selected. These types of checkboxes should have different names.
<input type="radio" id="radio_yes" name="radio_btn" value="Yes" /> Yes
<input type="radio" id="radio_no" name="radio_btn" value="No"
checked="checked" /> No
If you only want a single check box with the value yes to be returned if checked, then you can use a check box. You won't get any value if it isn't checked.
<input type="checkbox" id="chk_box" name="chk_box"
value="Yes" /> Do you want this?
On the server-side, you look for the value corresponding to the "radio_btn" (first example) or "chk_box" (second example) key in your form parameters.
Use the 'checked' property.
var checkbox = document.getElementById('checkboxId');
var checked = checkbox.checked;
look at the value of YourCheckboxName.Checked
If a checkbox is disabled, it will be omitted in the values collection submitted to the server even if it is checked:
<input type="checkbox" name="checkbox1">
<input type="checkbox" name="checkbox2" checked>
<input type="checkbox" name="checkbox3" disabled>
<input type="checkbox" name="checkbox4" disabled checked>
Looks like:
result of HTML sample code
Only checkbox2 is in the values collection submitted to the server, if the user submits the form without any changes.
