复选框值为0或1 [英] checkbox value 0 or 1

问题描述

在很多情况下，我的复选框如下

In many cases, I have checkboxes as below

 <input type="checkbox" name="custom7" value="1" id="custom7"
 checked="checked"> <label for="custom7">Email me more info?</label>

现在，当复选框被选中时，值应该为1，如value = 1。如果复选框未选中，我希望该值为零，如value = 0。我怎样才能做到这一点？

Now when the checkbox is checked the value should be 1 as in value=1 . If the checkbox is unchecked, I want the value to be zero as in value=0. How can I do this?
