Bruce432213 Posted May 9, 2019 Share Posted May 9, 2019 Hi, the html file is showing that it has changed the value in the XML file, but when I open the XML file nothing has changed. var status=xmlDoc.getElementsByTagName("Seats"); alert(status[2].getElementsByTagName("Status")[0].childNodes[0].nodeValue); //Unbooked status[2].getElementsByTagName("Status")[0].childNodes[0].nodeValue = "Booked"; alert(status[2].getElementsByTagName("Status")[0].childNodes[0].nodeValue); //Booked So, it changes from "Unbooked" to "Booked" but it doesn't change in the XML file. What's going on? Link to comment Share on other sites More sharing options...
justsomeguy Posted May 9, 2019 Share Posted May 9, 2019 Changing a data structure in Javascript does not change files on disk. Javascript running in a browser does not have permission to write to any files on your computer, thankfully. If you want to change files on the server you need to use a server-side language like PHP for that. Link to comment Share on other sites More sharing options...
