    copied!<p>I have three codes the first one is <code>html</code>:</p> <pre><code>&lt;html&gt; &lt;head&gt; &lt;script type = "text/javascript" src = "AJAX.js"&gt;&lt;/script&gt; &lt;/head&gt; &lt;body&gt; &lt;form method = "GET" &gt; &lt;input type = "text" id ="a" &gt;&lt;br&gt; &lt;input type = "text" id = "b"&gt;&lt;br&gt; &lt;input type = "button" value ="click" onclick = "process()"&gt;&lt;br&gt; &lt;textarea id = "underbutton" &gt;&lt;/textarea&gt;&lt;br&gt; &lt;/form&gt; &lt;body&gt; &lt;/html&gt; </code></pre> <p>Now javaScript (AJAX) :</p> <pre><code>function process() { if(xmlHttp.readyState==0 || xmlHttp.readyState==4){ a = document.getElementById("a").value; b = document.getElementById("b").value; xmlHttp.onreadystatechange = handleServerResponse; xmlHttp.open("GET","file.php?a="+a+"&amp;b="+b,true); xmlHttp.send(); } } function handleServerResponse (){ if(xmlHttp.readyState==4 &amp;&amp; xmlHttp.status==200) { response = xmlHttp.responseText; document.getElementById("underbutton").innerHTML = response ; } } </code></pre> <p>Now php file :</p> <pre><code>&lt;?php echo $_GET['a'].'&lt;br&gt;'; echo $_GET['b'].'&lt;br&gt;'; ?&gt; </code></pre> <p>everything is working but the problem is when I type in the first texbox (a) the word <code>hello</code> and the second (b) the code <code>&amp;</code> and click the button ; it must print out <code>hello&amp;</code>.<br> but it prints <code>hello</code>!!<br> just <code>hello</code> without <code>&amp;</code>.<br></p> <p>I noted that I was sending to php file is this : <code>file.php?a=hello&amp;b=&amp;</code>.<br> the last <code>&amp;</code> must be <code>%26</code> </p> <p>So to print out <code>&amp;</code> I must send : <code>file.php?a=hello&amp;b=%26</code>.<br> </p> <p>How can I fix that ??</p>
