jQuery在字段集中查找ID(jQuery find ID in a fieldset)

jQuery在字段集中查找ID(jQuery find ID in a fieldset)

我试图找到一个select fieldset的select元素的ID，我试过了

$('#fieldsetID select #idOfSelect');

和

$('#fieldsetID).find('select #idOfSelect');

两者在JS控制台中显示为未定义。

我究竟做错了什么？

干杯

I am trying to find a an ID of a select element inside a fieldset, I have tried

$('#fieldsetID select #idOfSelect');

And

$('#fieldsetID).find('select #idOfSelect');

Both appear as undefined in the JS console.

What am I doing wrong?

Cheers

不要在select和id之间放置空格，因为它是select的id而不是select的子id：

$('#fieldsetID select#idOfSelect');

要么，

$('#fieldsetID').find('select#idOfSelect');

Don't put space between select and it's id as it is the id of select not the children id of the select:

$('#fieldsetID select#idOfSelect');

Or,

$('#fieldsetID').find('select#idOfSelect');
