Auto Refresh IFrame HTML

How do I auto Refresh a Iframe every 3 Seconds with out it refreshing the entire page. I use <meta http-equiv="refresh" content="1"> but it shows the entire page refresh and puts you to the top of the page each time it does. My Iframe is pointed at a text file to read live messages I put in. Is there even a way to do this with out it refreshing the entire page, just the element. I am a HTML beginner so explain thoroughly please. I google alot and tried many things and so far nothing works and I try in many browser.

My code So Far:

<!DOCTYPE html>
<html>
<head>
<link rel="shortcut icon" href="favicon.png" type="image/x-icon" />



<title>Chat</title>

<style>

body{
margin: 0px;
}

h1{
font-family: arial;
font-size: 100%;
}
iframe{
width: 900px;
height: 500px;
}

div.top{
background-color: rgba(2, 109, 8, 0.83);
height: 30px;
width: 100%;
}
</style>


</head>

<body>
<div class="top">
<img src="favicon.png" alt="favicon"  height="31" width="31" >
<h1>Chat</h1>
</div>




<iframe src="text.txt" name="iframe_a"> />



</body>
</html>

<head>
    <script>
        function refreshIFrame() {
            var x = document.getElementById("*Your_iframe_id*");
            x.contentWindow.location.reload();
            var t = setTimeout(refreshIFrame, 3000);
        }
    </script>
</head>
<body onload="refreshIFrame()">... 
    <iframe id="*Your_iframe_id*" src= ...></iframe>...
</body>

this solution worked for me, I discovered that the 'refreshIFrame()' function was entered as a parameter without the braces () in the following line: " var t = setTimeout(refreshIFrame, 3000); ". Just substitute the relevant values and you are good to go.

You have problems with your html tags. (the "iframe" tag is malformed)

Here you have your code fixed and your answer ready to run: 

<!DOCTYPE html>
<html>
<head>
    <link rel="shortcut icon" href="favicon.png" type="image/x-icon" />
    <title>Chat</title>
    <style>
        body {
            margin: 0px;
        }
        h1 {
            font-family: arial;
            font-size: 100%;
        }
        iframe {
            width: 900px;
            height: 500px;
        }
        div.top {
            background-color: rgba(2, 109, 8, 0.83);
            height: 30px;
            width: 100%;
        }
    </style>
</head>
<body>
    <div class="top">
        <img src="favicon.png" alt="favicon" height="31" width="31">
        <h1>Chat</h1>
    </div>

    <iframe id="iframe" src="text.txt"></iframe>

    <script>
        window.setInterval(function() {
            reloadIFrame()
        }, 3000);

        function reloadIFrame() {
            console.log('reloading..');
            document.getElementById('iframe').contentWindow.location.reload();
        }
    </script>
</body>
</html>

You could accomplish what you need by simply using a few lines of Javascript.

 <script>
 window.setInterval("reloadIFrame();", 3000);

 function reloadIFrame() {
  document.frames["frameNameHere"].location.reload();
 }
 </script>
