javascript - 如何使用 jQuery 从 cookie 中删除特定的 cookie

Question

这是显示用于删除 cookie 的 URL 和删除图像的代码。添加和显示功能有效，但如何删除？？

function backLinks(){
    var pathname = window.location;
    var patientName = document.getElementById("general:patientDetailName").value;
    var cookieTimeVal = jQuery.cookie('PCC_Back_Button');
    if( cookieTimeVal== null){
        cookieTimeVal ="";
    }
    // for writing Cookie
    var stringCookie = "<span class='backLinkText1'><img src='../images/deleteImg.png' alt='' class='backLinkDeleteButton' onClick='deleteBackLink()'/></span><a class='backLinkText' href=\""+pathname+"\"> Patient History For \""+patientName+"\"</a>"+cookieTimeVal;
    jQuery.cookie('PCC_Back_Button', stringCookie , { expires: 1 });

    // read Cookie and set in HTML
    jQuery('#backButtonSpan').append(
        jQuery('<div>').attr({style:'padding-top:-10px;' }).append(cookieTimeVal)
    );
}

function deleteBackLink(val){
        jQuery.cookie(val, null);
    }

如何创建删除函数以及我将向其传递什么参数？

答对了...

在此我将替换 cookie 并删除内部 html

 function backLinks(stringValueAndName, patientName, patientDOB){
                var pathname = window.location;
                var cookieTimeVal = jQuery.cookie('PCC_Back_Button');
                if( cookieTimeVal== null){
                    cookieTimeVal ="";
                }

                var time = new Date();
                var spanId = time.getTime();

                // for wright in Cookie
                var stringCookie = "<span id ="+spanId+"> <img src='../images/deleteImg.png' class='backLinkDeleteButton' onClick='deleteBackLink("+spanId+")'/><a class='backLinkText' href=\""+pathname+"\">"+stringValueAndName +patientName+' ('+patientDOB +')'+"\</a></span>"+cookieTimeVal;
                jQuery.cookie('PCC_Back_Button', stringCookie , { expires: 1 });
                // read Cookie and set in HTML
                jQuery('#backButtonSpan').append(
                        jQuery('<div>').attr({style:'padding-top:-10px;' }).append(cookieTimeVal)
                    );
            }
    function deleteBackLink(val){
        jQuery('#'+val).remove();
        var stringCookie = jQuery('#backButtonSpan div').html();
        jQuery.cookie('PCC_Back_Button', stringCookie , { expires: 1 });
    }
