用于删除网站上部分img href的脚本

Question

I fired up a game guide on PrimaGames.com. The text is all fine but the images have busted src. Here's an example:

<img src="/media/files/eguide_assets/final-fantasy-xii-the-zodiac-age-eguide/085-105_walkthrough-web-resources/image/wi01.png/PRIMAP/resize/700x-1>">  

At the end of the src URL, you'll notice this odd string:
/PRIMAP/resize/700x-1>

I'm looking to set up a script (Stylish, Tampermonkey, etc) I can apply to PrimaGames.com so that it auto-removes that part of the src URL, which will in turn display the associated image.

Answer 1

Bookmarklet?

javascript:(function() { [...document.images].forEach(img => { 
  const src = img.src.split("/PRIMAP"); 
  if (src.length >=2) img.src=src[0]; })})()

Alternative for unknown stuff after the file extension - here assuming you are only interested in pngs

javascript:(function() { [...document.images].forEach(img => { 
  const end = img.src.lastIndexOf(".png/");
  if (end) img.src=img.src.substring(0,end+4); })})()

Answer 2

This is a fairly standard src rewrite task.

Here's a complete Tampermonkey / Violentmonkey script that should work on that site for both static and dynamic images :

// ==UserScript==
// @name     _Remove post file junk from image sources
// @match    *://primagames.com/*
// @noframes
// @require  https://ajax.googleapis.com/ajax/libs/jquery/2.1.0/jquery.min.js
// @require  https://gist.github.com/raw/2625891/waitForKeyElements.js
// @grant    GM_addStyle
// @grant    GM.getValue
// ==/UserScript==
// @grant    none
//- The @grant directives are needed to restore the proper sandbox.
/* global waitForKeyElements */

waitForKeyElements ("img", fixImgSource);

function fixImgSource (jNode) {
    var oldSrc = jNode.attr ("src");
    //-- Does the src have junk after the file suffix?
    if (/\.(png|jpg|gif)./i.test (oldSrc) ) {
        let newSrc = oldSrc.replace (/\.(png|jpg|gif).+$/i, ".$1");
        jNode.attr ("src", newSrc);
    }
}

You will need to find the index where the actual image ends and create a substring up to that index.

function removeTag(image) {
    var src = image.src.toString();
    var imgFormats = ['jpg', 'jpeg', 'gif', 'png'];
    var idx;
    imgFormats.forEach(fmt => {
        if (src.lastIndexOf(fmt) > -1) {
            idx = src.lastIndexOf(fmt) + fmt.length;
        }
    })
    if (typeof idx !== 'undefined') {
        image.src = src.substr(0, idx + 1);
    }
}

If you know that every extra string will start with '/PRIMAP', then you can use the solution provided by above.

You just need to execute below code, Here I am just replave image src with image url, after replacing src

(function(){
  var a = document.getElementsByTagName('img');
  for(e of a){
    let t = e.src;
    e.src = t.replace(/(http|https|file:\/\/)?(\/.*\.(?:png|jpg))(.*)/i, '$2');
}
}())

Here I am changing:

/media/files/eguide_assets/final-fantasy-xii-the-zodiac-age-eguide/085-105_walkthrough-web-resources/image/wi01.png/PRIMAP/resize/700x-1%3E

to

/media/files/eguide_assets/final-fantasy-xii-the-zodiac-age-eguide/085-105_walkthrough-web-resources/image/wi01.png

Then url taking File from relative path that is why I am using file path,

If this image in you relative folder then you will get image, Else you need to add base url with the relative path

as https://primagames.com/ then relative path mean code will change to :

(function(){
      var a = document.getElementsByTagName('img');
      for(e of a){
        let t = e.src;
        e.src = `https://primagames.com${t.replace(/(http|https|file:\/\/)?(\/.*\.(?:png|jpg))(.*)/i, '$2')}`;
    }
    }());

It will work for you.

For Only remove extra stuff from image url, that is "/PRIMAP/resize/700x-1%3E", You can do below code

(function(){
    var a = document.getElementsByTagName('img');
    for(e of a){
       let t = e.src;
       e.src = t.replace(/([\w-]+\.(jpg|png|txt))(.*)/i, '$1');
    }
}())
