我有两个页面，第一页是index.php，我也在其中使用facebox框架。第二页是addevent.php，我尝试了多种方法来捕获addevent.php中单个复选框的值并将其传递给index.php。但它没有显示出值(value)。那么我的代码有问题吗？我想念什么？任何帮助将不胜感激..
index.php
echo ">".$check=$_REQUEST['check'];
echo "check[0]: ".$check[0];

最佳答案
如果您包含 jQuery 库，为什么不使用 jQuery？
var checkbox_val=jQuery("#CHECKBOX_ID_HERE").val();//gets you the value regardless if checked or not
var checkbox_val=jQuery("#CHECKBOX_ID_HERE").attr("checked"); //returns checked status
或
var global_variable=""; //should be initialized outside any function
jQuery("#FORM_ID_HERE").children(":input[type='checkbox']").each(function(){
if (jQuery(this).attr("checked"))global_variable+="&"+jQuery(this).attr("name")+"="+jQuery(this).val();
});
这只是一个开始的建议，并不理想。理想的部分是在表单中使用 []。
