Wikipedia:WikiProject User scripts/Scripts/Edit Top - Wikipedia

Ever want to just change something at the top of a fairly long article, but don't feel like loading the entire page again like the "Edit this page" link does? Well, now you can do just that, using this wiki user script!

To install the script:

• Go to Special:Mypage/monobook.js and click "Edit this page"
• Copy/Paste the following script into the edit box, and save. Follow the displayed instruction to bypass your browser cache.

A slightly modified version is also available as an includable script at Gerbrant.edit.top.

JavaScript

// This will add an [edit] link at the top of all pages except preview pages and the main page
// by User:Pile0nades

// Add an [edit] link to pages
addOnloadHook(function () {
  // if this is preview page or generated page, stop
  if(
    document.getElementById("wikiPreview") ||
    document.getElementById("histlegend‎") ||
    document.getElementById("difference‎") ||
    document.getElementById("watchdetails") ||
    window.location.href.indexOf("/wiki/Special:") != -1
  ) {
    if(window.location.href.indexOf("&action=edit&section=0") != -1) {
      document.getElementById("wpSummary").value = "/* Intro */ ";
    }
    return;
  };

  // get the page title
  var pageTitle = wgPageName;

  // create div and set innerHTML to link
  var divContainer = document.createElement("div");
  divContainer.innerHTML = '<div class="editsection">[<a href="/w/index.php?title='+pageTitle+'&action=edit&section=0" title="Edit section: '+pageTitle+'">edit intro</a>]</div>';

  // insert divContainer into the DOM below the h1
  if(window.location.href.indexOf("&action=edit") == -1) {
    document.getElementById("content").insertBefore(divContainer, document.getElementsByTagName("h1")[0]);
  }

});

Now go to any page on Wikipedia and the [edit intro] link will appear at the top right. This link will load only the "zeroth" section of the article into the edit page.
