面对ChecxBox上的问题Checked or not event，not working propertyly

Question

JavaScript代码：

if (document.getElementsByClassName('chkaddress').checked) {
    $('#DivCommunicationAddress').show();
}
else {
   $('#DivCommunicationAddress').hide();
}

Razor查看：

@Html.CustomCheckBoxFor(Employee => Employee.IsActive, new { @class = "ui-checkbox chkaddress" })
@Html.LabelFor(Employee=>Employee.IsActive, "Same As Home Address")

当我选中复选框时，不会进入if块。它仅转到else块。

Answer 1

document.getElementsByClassName('chkaddress')返回集合。您必须使用以下内容指定特定索引：

document.getElementsByClassName('chkaddress')[0].checked
