how to save xml files using Javascript?
I tried to
1) load an xml file using javascript as an object, say note.xml
2) then save the object to a new xml file, say note_new.xml
I did 1) but failed 2)
I tried to use method save() to do 2). After my failure, I checked ms site and they said save() is not supported....
could some one enlighten me how to do the save?
thank you!
here is the code:
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/>
</head>
<body>
<h1>W3Schools Internal Note</h1>
<p><b>To:</b> <span id="to"></span><br />
<b>From:</b> <span id="from"></span><br />
<b>Message:</b> <span id="message"></span>
<script type="text/javascript">
if (window.ActiveXObject){
alert("there is ActiveXObject");
var xmlDoc = new ActiveXObject("Microsoft.XMLDOM");
xmlDoc.async=false;
xmlDoc.load("note.xml");
}else{
alert("i am not withActiveXObject!");
xhttp=new XMLHttpRequest();
xhttp.open("GET","note.xml",false);
xhttp.send("");
xmlDoc=xhttp.responseXML;
}
xmlDoc.save("note_new.xml");
</script>
</body>
</html>
update:
seems this is related to security issue. I appologize to those experienced programmers for my putting this question in a rush because it seems a newbi开发者_运维问答e question.
Your problem is: javaScript does not have an input/output (I/O) API as it is a client-side scripting language and consequently has no access to the file system via the server. You would need to use a server-side scripting language to save data to a server. There may be hacks to solve your problem client-side, but they are probably either unsave or otherwise buggy. (btw: what api is the save method member of? Did you make that up?)
What you can do is save data temporarily to any DOM element (e.g. window, or a javaScript) object. There is however no way to make these changes permanent.
In your case, looking in to PHP scripting might be the best way to go.
