if Html.CheckBox is checked or not

Question

I have a simple question regarding html.checkbox

Using this as an example:

@Html.CheckBox("IncreaseStock", Model.IncreaseStock == null ? false : (bool)Model.IncreaseStock)

now doing a alert to see if the checkbox is tick or not:

var IncreaseStock = $('#IncreaseStock').val();

if (IncreaseStock == true) {
    alert("true ")
} else {
    alert("NOT TRUE")
}

However when its false it still shows as true, even though i didnt click the check box.

Any ideas

Answer 1

Instead of

$('#IncreaseStock').val();

You want

$('#IncreaseStock').prop('checked')

Answer 2

Using jQuery you can check like this

if($('#IncreaseStock').is(':checked')){
   alert('true');
}
else{
 alert('false');
}
