Code that you insert on this page could contain malicious content capable of compromising your account. If you import a script from another page with "importScript", "mw.loader.load", "iusc", or "lusc", take note that this causes you to dynamically load a remote script, which could be changed by others. Editors are responsible for all edits and actions they perform, including by scripts. User scripts are not centrally supported and may malfunction or become inoperable due to software changes. A guide to help you find broken scripts is available. If you are unsure whether code you are adding to this page is safe, you can ask at the appropriate village pump.

//This script removes en dashes from list items. 
//It is a test script, which will be developed into one for toggling list item annotations. 
//Based on a script by Writ Keeper.

//This selector grabs all of the <li> elements that are within #mw-content-text, and then does something for each of them
$("#mw-content-text li").each( function (ind, el) 
{ 
  //first, grab the text from the current li element; we want only the top level text, so filter out all of the other stuff.
  var currentText = $(el).contents();

  //Only process if there's something there to process
  if(currentText.text().length > 0)
  {
     // replace the character
     var newText = currentText.text().replace(/ – .*?$/g,' – ');  
     
     //reinsert the updated string back into the DOM
     currentText.replaceWith(newText);
