I have digital information written as Javascript variables by PHP into a .txt-File. This information gets changed by a user at a different interval.
var ISTUHSXDATE8 = '21.1.2018';
var ISTUHSXTIME8 = '20:11';
var ISTUHSXROT8 = 0;
var ISTUHSXGELB8 = 0;
var ISTUHSXGRUEN8 = 1;
var ISTUHSXAUSLASTUNG8 = '0%';
To show actual information in the HTML body, it´s necessary to make the HTML document load the latest version of .txt from server. [At the moment handmade by push the button and in webprojekt by setInterval() automatically]
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="expires" content="0">
<meta http-equiv="pragma" content="no-cache">
<meta http-equiv='cache-control' content='no-cache'>
<script type="text/javascript" id="id_of_java_var"></script>
</head>
<body>
<button onclick="myFunction()">Try it</button>
<script>
function myFunction() {
var dsts = new Date();
document.getElementById("id_of_java_var").src =
"https://www.juh-technik.de/StreifenstatusEA1.txt?time" + dsts.getTime();
}
</script>
</body>
</html>
With this code I can load latest version from the server for several .gif/.jpg/.html files by pushing the refresh button. The Problem is, this don´t works with .txt-files.
So my question is, how to refresh src of following line without page reload.
<script src="https://www.juh-technik.de/StreifenstatusEA1.txt" type="text/javascript" id="id_of_java_var"></script>
Thanks for your help :-)
setInterval()(w3schools.com/js/js_timing.asp), but the rest of the text is very confusing.
