如何根据链接的标题属性的不同短语来更改链接的文本? [英] How to change a link's text based on different phrasing of the link's title attribute?

问题描述

在我的梦幻足球页面上，它提供了有关对方球队的统计信息，当您将鼠标悬停在其上时，它会告诉您他们放弃了多少分(参见图片).

In my Fantasy football page, it gives stats about the opposing team and when you mouseover it tells you how many points they give up (See picture).

以下是与此相关的代码:

Here is the relevant code pertaining to this:

<a class="Inline F-rank-good" title="WAS gives up the 3rd most fantasy points to the QB position." target="_blank" href="/f1/777400/pointsagainst?pos=QB&ntid=28">Was</a>

如何创建Greasemonkey脚本，该脚本会将#添加到团队名称的末尾(即"Was"变成"Was-3"

How do I create a Greasemonkey script that will add the # to the end of the team name (i.e. "Was" becomes "Was - 3"

有一个问题是，有时排名会说它放弃了第二最少的分数"，在这种情况下，您必须做32-2才能获得绝对排名.

One problem there is, is that sometimes the rank says it gives up the "2nd fewest points", in which case you would have to do 32-2 to get the absolute rank.

推荐答案

使用基于周围文本进行切换的正则表达式从title属性中提取数字.

Extract the number from the title attribute, using regex that switches based on the surrounding text.

以下完整但未经测试的Greasemonkey脚本说明了该过程:

The following, complete but untested, Greasemonkey script illustrates the process:

// ==UserScript==
// @name     FF, stat delinker
// @include  http://YOUR_SERVER.COM/YOUR_PATH/*
// @require  http://ajax.googleapis.com/ajax/libs/jquery/2.1.0/jquery.min.js
// @require  https://gist.github.com/raw/2625891/waitForKeyElements.js
// @grant    GM_addStyle
// ==/UserScript==
/*- The @grant directive is needed to work around a design change
    introduced in GM 1.0.   It restores the sandbox.
*/
waitForKeyElements ("a.Inline", delinkChangeStat);

function delinkChangeStat (jNode) {
    var rawText     = jNode.attr ("title")  ||  "";
    var deltaText   = "";
    var mtchResult  = null;

    //-- IMPORTANT: the single =, in the if() statements, is deliberate.

    //-- Like "gives up the 3rd most"
    if (mtchResult  = rawText.match (/gives up the (\d+)[a-t]{2} most/i) ) {
        deltaText   = mtchResult[1]; 
    }
    //-- Like "gives up the 2nd fewest points"
    else if (mtchResult = rawText.match (/gives up the (\d+)[a-t]{2} fewest/i) ) {
        deltaText   = 32 - parseInt (mtchResult[1], 10); 
    }
    //-- ADD ADDITIONAL else if() CLAUSES HERE AS NEEDED.

    //-- Change the link
    if (deltaText) {
        jNode.text (jNode.text () + " - " + deltaText);
    }
}
