但是它不起作用.我在做什么错了?

but it doesn't work. What am I doing wrong?

推荐答案

我认为您要小写检查值吗?试试:

I think you want to lowercase the checked value? Try:

var jIsHasKids = $('#chkIsHasKids:checked').val().toLowerCase();

或者您要检查它，然后将其值转换为小写:

or you want to check it, then get its value as lowercase:

var jIsHasKids = $('#chkIsHasKids').attr("checked", true).val().toLowerCase();
