javascript - 测试是否使用jQuery选中了复选框(Testing if a checkbox is checked with jQuery)

Question

If the checkbox is checked, then I only need to get the value as 1;

(如果选中该复选框，那么我只需要将值设为1;)

otherwise, I need to get it as 0. How do I do this using jQuery?

(否则，我需要将其设为0.如何使用jQuery执行此操作？)

$("#ans").val() will always give me one right in this case:

($("#ans").val()在这种情况下总是给我一个权利：)

<input type="checkbox" id="ans" value="1" />

Answer 1

Use .is(':checked') to determine whether or not it's checked, and then set your value accordingly.

(使用.is(':checked')确定是否已选中，然后相应地设置您的值。)
