首先,您必须查看是否选中了复选框：

$("#yourSelector").live("click",function(){
        var id = parseInt($(this).val(),10);
        if($(this).is(":checked")) {
            // checkBox is checked -> do something
        } else {
            // checkBox is not checked -> do something different
        }
});

您可以通过Ajax加载特定内容：

$.ajax({
                type: "POST",dataType: "xml",url: "path/to/file.PHP",data: "function=loadContent&id=" + id,success: function(xml) {
                    // success function is called when data came back
                    // for example: get your content and display it on your site
                }
});
