Answer 1

In order to check whether a checkbox is checked or not you can try using .is() as shown :-

jQuery syntax.

$('#Baruc').is(':checked') // it returns bool if checkbox is checked it will return 'true' otherwise 'false'.

Edit :- there must be a colon before checked

Javascipt syntax.

if(document.getElementById("Baruc").checked)
{
   //checkbox is checked
}

Answer 2

Solution 1:

You need to use .length for checked elements.

if($("#Baruc:checked").length){
  //checkbox is checked
}

Solution 2:

also you can use .is() method with :checked selector:

if($("#Baruc").is(":checked")){
  //checkbox is checked
}

Answer 3

Use this

$('#Baruc').is('checked');

Answer 4

you can pass this in your onchange function:

onchange="showlabel(this);

now in your method you can use this:

function showlabel(elem){
    alert(elem.checked); // true if checked false if unchecked
}

function showlabel(elem){ alert(elem.checked);}

<input id="Baruc" type="checkbox" value="true" name="Baruc" data-val-required="The Baruc field is required." data-val="true" onchange="showlabel(this);">
