Here's a simple runable example that just logs the content of the data to your console
<!DOCTYPE html>
<html lang="de">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<script>
function getData(jsonp){
console.log(jsonp);
}
var scripts = document.createElement('script');
scripts.src = 'http://intranet.ooelfv.at/webext2/getjson.php?scope=laufend&callback=getData';
document.body.appendChild(scripts);
</script>
</body>
</html>
You can access the data by modifying the getData function. For example, to get the title, you can use
function getData(jsonp){
console.log(jsonp.title);
}

There are some errors in the formation of their return string.
I made some adjustments in your return string copying and pasting it on this site .
I think you need something to get the keys and their respective values:
var data = '{"webext2":true,"version":"1.2","title":"laufende Eins\u00e4tze","pubDate":"Mon, 03 Oct 2016 19:01:02 +0200","cnt_feuerwehren":3,"cnt_einsaetze":2,"einsaetze":{"0":{"einsatz":{"num1":"E161000221","einsatzort":"PE - PABNEUKIRCHEN","startzeit":"Mon, 03 Oct 2016 18:24:17 +0200","inzeit":"","status":"offen","alarmstufe":1,"einsatzart":"BRAND","einsatztyp":{"id":"BK","text":"BRAND KLEIN FEUERWEHREINSATZ"},"einsatzsubtyp":{"id":"KAMIN-BK","text":"BRAND KAMIN"},"adresse":{"default":"NEUDORF 21","earea":"NEUDORF","emun":"PABNEUKIRCHEN","efeanme":"NEUDORF","estnum":"21","ecompl":""},"wgs84":{"lng":14.829464095886,"lat":48.349240803097},"bezirk":{"id":7,"text":"Perg"},"cntfeuerwehren":2,"feuerwehren":{"407107":{"feuerwehr":"FF Pabneukirchen"},"407109":{"feuerwehr":"FF Riedersdorf"}}}},"1":{"einsatz":{"num1":"E161000213","einsatzort":"RI - RIED IM INNKREIS","startzeit":"Mon, 03 Oct 2016 17:57:39 +0200","inzeit":"","status":"offen","alarmstufe":1,"einsatzart":"TEE","einsatztyp":{"id":"TK","text":"TECHNISCH KLEIN FEUERWEHREINSATZ"},"einsatzsubtyp":{"id":"OELSPUR-TK","text":"\u00d6LSPUR, \u00d6LAUSTRITT"},"adresse":{"default":"RIED IM INNKREIS","earea":"RIED IM INNKREIS","emun":"RIED IM INNKREIS","efeanme":"","estnum":"","ecompl":"SCH\u00c4RDINGER TOR"},"wgs84":{"lng":13.488453771887,"lat":48.212407174905},"bezirk":{"id":8,"text":"Ried"},"cntfeuerwehren":1,"feuerwehren":{"408223":{"feuerwehr":"FF Ried im Innkreis"}}}}}}';
var jsondata = JSON.parse(data);
check_json_data(jsondata);
function check_json_data(jsondata) {
for (var propertyName in jsondata) {
if (propertyName) {
if (typeof jsondata[propertyName] == 'object') {
check_json_data(jsondata[propertyName]);
}
else {
console.log(propertyName + ": " + jsondata[propertyName])
}
}
}
}

i think you can use ajax.
$.ajax({
url: "ajaxurl.php or whatever",
type: "POST",
data: {
data:datayouwattosend,
},
async: false,
statusCode: {
404: function () {
alert("not found");
}
},
success: function (data) {
console.log(data);
}
})
here is a complete example where you can find information about this.
