    copied!<p>I'm new to this so please bear with me. I am trying to write a chrome extension that does the following:</p> <ol> <li>Detect www.website.com/anypage.html. If this website is detected, then do the following.</li> <li>Don't load the URL. </li> <li>Instead, write a blank document with a hyperlink to www.website.com/anypage.html?ie=UTF8</li> </ol> <p>The script is set to run at document start (in the manifest). </p> <p>Here is my code:</p> <p>Detect URL:</p> <pre><code>var regExp = /website.com/gi; var match = 0; testString = window.location.href.toString(); if(regExp.test(testString) { match = 1; </code></pre> <p>Write blank document with link to the URL with the UTF8 encoding tag:</p> <pre><code>document.write("&lt;a href=" + window.location.href + "?ie=UTF8&gt;Title of Link&lt;/a&gt;"); </code></pre> <p>This doesn't work as expected, and just shows a blank page. Anyone have any ideas?</p> <p>Thanks!</p> <hr> <p>EDIT: Here is the full code:</p> <pre><code>checklink(); // If there is a match, then checklink will return a 1. If it's already tagged, it will return a 5. var matchLink = null; if (checklink() === 1) { matchLink = window.location.href.toString(); if (checklink() != 1) { matchLink = null; function checklink() { //checks to see if the current URL matches website.com var regExp = /website.com/gi, testString = window.location.href.toString(), match = 0, tagged = 0; if (regExp.test(testString)) { //if there is a match, returns 1 match = 1; var regExp2 = /UTF8/gi; if (regExp2.test(testString)) { //if UTF8 is found, then it returns 5 tagged = 5; return(match + tagged); function tagUTF() { if (matchLink) { var newLink = matchLink + "?ie=UTF8"; document.write("&lt;a href=\"" + newLink + "\"&gt;Link&lt;/a&gt;"); if (matchLink) { tagUTF(); } </code></pre>
