    copied!<p>I want to make a cookie to remember a radius that a user can choose. The problem is that the cookie works, but the value of the cookie is undefined. I don't know what I am doing wrong.</p> <p>The function "opslaan" is linked with a button on the HTML page.</p> <pre><code>function opslaan() { createCookie('radius',document.getElementById("range").value,8); alert("opgeslagen"); } function readCookie(name) { var nameEQ = name + "="; var ca = document.cookie.split(';'); for(var i=0; i &lt; ca.length; i++) { var c = ca[i]; while (c.charAt(0)==' ') c = c.substring(1,c.length); if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length,c.length); } return null; } function createCookie(name,value,days) { if (days) { var date = new Date(); date.setTime(date.getTime() + (days*24*60*60*1000)); var expires = ";expires=" + date.toGMTString(); } else var expires = ""; document.cookie = name + "=" + value + expires +";path=/"; } </code></pre> <p>This is the button and the range field where it need to get the value out:</p> <pre><code>&lt;fieldset class="one-third column"&gt; &lt;label for=""&gt;Radius van de kaart (km)&lt;/label&gt; &lt;input type="range" min="5" max="20" value="5" step="5" onchange="showValue(this.value)" /&gt; &lt;span id="range"&gt;5&lt;/span&gt; &lt;script type="text/javascript"&gt; function showValue(newValue) { document.getElementById("range").innerHTML=newValue; } &lt;/script&gt; &lt;/fieldset&gt; &lt;script&gt; alert(readCookie('radius')); &lt;/script&gt; &lt;div class="one-third column"&gt; &lt;a class="full-width button margin-top25" href="home.html" onclick="opslaan()"&gt; Opslaan &lt;/a&gt; &lt;/div&gt; </code></pre> <p>It seems to be working without the range field and button.</p>
