Hi There,
I am using SVG, Javascript with dsp objects (dsp-server page
scripting language). Now, I have to grab data from svg graph, which
user can change, to the server for inserting into database.
I have to find a way to communicate with server from svg file. I
have to send two whole arrays of values to server so server can
insert them into database. I thought if I can transfer this array to
xml file, and render a dsp sripct (dsp is a server page sripting
language) object, I can insert into database.
I have tried using two different ways:
js_Vol is a javascript array which needs to be sent to server
the database here is an object oriented and custom made.
function send(){
alert(js_Vol);
vol = '{'+js_Vol+'}';
var xmlDoc = new ActiveXObject("Microsoft.XMLDOM");
alert("I am HERE");
xmlDoc.async="false";
xmlDoc.load("writeNewStrikeVol.xml?AnchorVols="+vol);
}
this does not work, I do not get alert: "I am HERE" upon execution.
I also tried
var xmlHttp=new ActiveXObject("Microsoft.XMLHTTP");
instead of
var xmlDoc = new ActiveXObject("Microsoft.XMLDOM");
which also doesn't work :(
=>
Other way I thought of trying with getURL() and parseXML() which
also does not work.. I don't get alert("past getURL)
function send(){
alert(js_Vol);
vol = '{'+js_VolY+'}';
getURL("writeNewStrikeVol.xml?AnchorVols="+vol, testFunction);
//getURL("writeNewStrikeVol.xml", testFunction);
alert("past getURL");
}
function testFunction(obj){
var string = '';
if(obj.success){
string = obj.content;
}
alert(string);
var vol = parseXML(obj.content,svgDocument);
var volId=vol.firstChild.getAttribute("id");
alert(svgDocument);
var volData=vol.firstChild.firstChild.getData();
alert("ID = "+volId+" and the tag contents =
\""+volData+"\"");
}
and if I just say
getURL("writeNewStrikeVol.xml",
testFunction);
I can get past the alert, and all other alerts are shown as blank =
null except svgDocument.
my xml file is:
<?xml version='1.0'?>
<newvol id="1000">
<!-- DSP
Task.setParameter("aVols",22);
test.render();
-->
<!-- DSPOBJECT name = setVolNew
sql = update NewVols set AnchorVols=aVol;
-->
<!-- DSPOBJECT name = test
aStrikes
aVols
-->
</newvol>
Thank you very much for any suggestion.
