JSON object toJSONstring( )

[Claus Mygind]

I see a lot of references to "toJSONstring()", but nothing on how to construct it or if it defined in some library.

I have been able to construct my jsonObject which is a collection of 3 sets of data 1) a polygon with variable number of vertices, 2) a variable list of feature points lat/lng 3) a corresponding list of feature attributes describing the feature points.

I want to send this information via ajax to my web server for processing.

From JSON.orgI have downloaded both json.js and json2.js, I see the relatively new json2 supersedes json. Also in json2 "toJSONstring() is no longer used. Instead it is " JSON.stringify(value, replacer, space)"

Below is my code and below that some sample data. My question is how do I execute line 34 of this code.

I have an object myJrec created on line 24. This object has to be json stringified? How do I do that? Note - I have linked the json2.js to my html page, so it is available to act upon myJrec.

//save layout section
function saveLayout() {
 
    // Since this Polygon only has one path, we can call getPath()
    // to return the MVCArray of LatLngs
    var vertices = poly.getPath();
    var jobSite = '{"JOBSITE":[';
    // get job site location.
    for (var i =0; i < vertices.length; i++) {
        var xy = vertices.getAt(i);
            jobSite += '{"VERTICE":"' + xy.lat() +" " + xy.lng() + '"},';
    }
    jobSite = jobSite.substring(0,jobSite.lastIndexOf(","))+']';
    //get marked features on job site
    var featureAttrib = '"FEATUREATTRIB":[';
    var featurePoints = '"FEATUREPOINTS":[';
    for (var i = 0; i < markersArray.length; i++ )
    {
            featureAttrib += '{"FEATURE":"' + exchangeArray[i].feature + '","ICON":"' + exchangeArray[i].iconColor + '"},';
            featurePoints += '{"POINT":"'   + markersArray[0].position.lat() +' '+ markersArray[0].position.lng() + '"},';
    }
    featureAttrib = featureAttrib.substring(0,featureAttrib.lastIndexOf(","))+']';
    featurePoints = featurePoints.substring(0,featurePoints.lastIndexOf(","))+']}';
    var myJrec  = eval("("+jobSite + ',' + featureAttrib + ','+ featurePoints+")");
 
    var request = window.ActiveXObject ?
        new ActiveXObject('Microsoft.XMLHTTP') :
        new XMLHttpRequest;
 
    var url = 'saveProjectLayout.exe?timeStamp=' + new Date().getTime();
    request.open("POST", url, true);
    request.onreadystatechange = updatePage;
    request.setRequestHeader("Content-Type", "application/x-www-form-urlencoded");
    request.send(myJrec.toJsonString());
 
}
 
 

Sample data my json object myJrec

{"JOBSITE":[{"VERTICE":"41.75076232883921 -88.15228931877138"},{"VERTICE":"41.748264959811564 -88.15768592330934"},{"VERTICE":"41.747984800174116 -88.15771810981752"},{"VERTICE":"41.7480568413405 -88.15235369178774"}],"FEATUREATTRIB":[{"FEATURE":"p1","ICON":"iconb"},{"FEATURE":"p2","I CON":"icong"},{"FEATURE":"p3","ICON":"iconr"},{"FE ATURE":"p4","ICON":"iconr"},{"FEATURE":"p5","ICON" :"icony"}],"FEATUREPOINTS":[{"POINT":"41.74914945578666 -88.1549768922043"},{"POINT":"41.74914945578666 -88.1549768922043"},{"POINT":"41.74914945578666 -88.1549768922043"},{"POINT":"41.74914945578666 -88.1549768922043"},{"POINT":"41.74914945578666 -88.1549768922043"}]}

I got this one figured out. Actually pretty easy

from this
request.send(myJrec.toJsonString());

to this
request.send(jSON.stingify(myJrec));

with the the json2.js file linked to the html page
