Question

我之前得到了一些帮助，但不知何故，我再也无法让它发挥作用了。我需要一个文本框，如果其他＆＃39;选中复选框，并在未选中时消失。有人知道是什么给出的吗？

试试这个：

$(document).ready(function() { 
    $('#other').change(function(){ 
        $('#otherrace').toggle(this.checked);
    });
});

看到它正常工作：http://jsfiddle.net/karim79/2hw89/

此外，您的文档中有两个id =“other”的元素，无效。

最后，当选中复选框时，您可以通过关注“其他”文本输入使您的表单更加可用，从而使用户不必回家，如下所示：

$('#other').change(function(){ 
    $('#otherrace').toggle(this.checked).focus();
});

根据复选框-jQuery的状态切换文本框的可见性
