Example

// Example for value as string  
function uploadFile1()
{
    try{
    var request = new voltmx.net.HttpRequest();
    glob_req = request;
    .....
    var frmData= new voltmx.net.FormData();
    frmData.append("param1","VOLTMX LABS"); 
    }  
       catch(ex){
    frmSend.responseTA.text=ex.message;
    }    
}  
// Example for value as rawbytes for file upload  
function uploadFile2()
{  
    try{
    var request = new voltmx.net.HttpRequest();
    glob_req = request;
    .....
    var frmData= new voltmx.net.FormData();  
       var path = voltmx.io.FileSystem.getDataDirectoryPath() + "/SampleImage.png"  
var f1 = voltmx.io.FileSystem.getFile(path);  
//Filename with rawbytes  
frmData.append(f1.name, f1.read());  
       }  
       catch(ex){
        frmSend.responseTA.text=ex.message;
       }     
}
