How to call a JavaScript function from PHP?
<p>How to call a JavaScript function from PHP?</p>

<pre><code>&lt;?php

  jsfunction();
  // or
  echo(jsfunction());
  // or
  // Anything else?
</code></pre>

<p>The following code is from <em>xyz.html</em> (on a button click) it calls a <code>wait()</code> in an external <em>xyz.js</em>. This <code>wait()</code> calls wait.php.</p>

<pre><code>function wait() 
{
  xmlhttp=GetXmlHttpObject();
  var url="wait.php"; \
  xmlhttp.onreadystatechange=statechanged; 
  xmlhttp.open("GET", url, true); 
  xmlhttp.send(null);
} 

function statechanged()
{ 
  if(xmlhttp.readyState==4) {
       document.getElementById("txt").innerHTML=xmlhttp.responseText;
  }
}
</code></pre>

<p>and <em>wait.php</em></p>

<pre><code>&lt;?php echo "&lt;script&gt; loadxml(); &lt;/script&gt;"; 
</code></pre>

<p>where <code>loadxml()</code> calls code from another PHP file the same way. </p>

<p>The <code>loadxml()</code> is working fine otherwise, but it is not being called the way I want it.</p>
