如何使用Jquery在asp.net视图中检查复选框是否已选中？

Question

I am trying to find out whenever a checkbox on my page is checked and unchecked. I console log to find out the status, but I am always getting an "unchecked" result. What am I doing wrong?

...
<input type="checkbox" id="checkbox_addAuthor" name="checkbox_addAuthor" />

</div>
</form>

@section Scripts
{
<script type="text/javascript">
    var checkbox = $('#checkbox_addAuthor');
    var authorList = $('#AuthorList');

    checkbox.on('click',function(){

        if(checkbox.Checked == true)
        {
           console.log("I am checked")
        }
        else {
            console.log("I am not checked");
        }

    })

</script>
}

When I run this, the console always prints out "I am not checked". Cant figure out why.

Answer 1

$('#checkbox_addAuthor :checkbox:checked').length > 0;

Answer 2

you can use the prop

if($('#checkbox_addAuthor').prop('checked'))
 {
    // something when checked
 }
else {
   // something else when not
 }

Answer 3

使用$('#checkbox_addAuthor').val() == "on"来检查复选框的状态
