JQuery get value of checkbox only if checked
提问by RIK
At the moment I am using the following bit of code to only get the values of checked checkboxes, however I am sure that there is an easier way that this.
目前我正在使用以下代码来仅获取选中复选框的值，但是我确信有一种更简单的方法。
if ($('#OPTtags-adventure-diving').is(':checked')) {
var OPTtags-adventure-diving = $('#OPTtags-adventure-diving').val()
} else var OPTtags-adventure-diving = '';
if ($('#OPTtags-master-scuba-diver').is(':checked')) {
var OPTtags-master-scuba-diver = $('#OPTtags-master-scuba-diver').val()
} else var OPTtags-master-scuba-diver = '';
Is there?

I have not checked this, but how about
我没有检查过这个，但是怎么样
var OPTtags-master-scuba-diver = $('#OPTtags-adventure-diving:checked').val()
var OPTtags-master-scuba-diver = $('#OPTtags-adventure-diving:checked').val()
Then your variable will be undefinedor the value.
那么你的变量将是undefined或值。
