Javascript Solutions
Solution 1 - Javascript
You can use the pseudo-selector :checkbox with a call to jQuery's is function:
$('#myinput').is(':checkbox')
Solution 2 - Javascript
>>> a=$("#communitymode")[0]
<input id="communitymode" type="checkbox" name="communitymode">
>>> a.type
"checkbox"
Or, more of the style of jQuery:
$("#myinput").attr('type') == 'checkbox'
Solution 3 - Javascript
$("#myinput").attr('type') == 'checkbox'
Solution 4 - Javascript
A non-jQuery solution is much like a jQuery solution:
document.querySelector('#myinput').getAttribute('type') === 'checkbox'
Solution 5 - Javascript
Use this function:
function is_checkbox(selector) {
var $result = $(selector);
return $result[0] && $result[0].type === 'checkbox';
};
Or this jquery plugin:
$.fn.is_checkbox = function () { return this.is(':checkbox'); };
Solution 6 - Javascript
$('#myinput').is(':checkbox')
this is the only work, to solve the issue to detect if checkbox checked or not. It returns true or false, I search it for hours and try everything, now its work to be clear I use EDG as browser and W2UI
