i have a situation in which i have a byte array of a image in code behind C# class of a webpage (pop up page)
protected void ToFile(byte[] byteImage)
{
string strByte = byteImage.ToString();
this.Context.Response.Write("<script type='text/javascript'>window.frameElement.commitPopup('" + byteImage + "');</script>");
this.Context.Response.End();
}
i want to get pass byteImage to the handler function i.e .in javascript / on parent page
function onDialogClose(dialogResult,returnValue) {
if (dialogResult == SP.UI.DialogResult.OK) {
//var inputBuffer = new System.Byte(returnValue.length);
//var byte = new Array();
//byte = returnValue;
how to get the byte array at returnValue
(now it contains System.Byte[]) only
is there any way to access C3 byte[] array from Javascript??
thankx
You could use the base64 encoding to encode the byte array safely:
var result = Convert.ToBase64String(bytes);
Of course, in order to access the original byte values in JavaScript, you’ll have to convert it back on the JavaScript side. There is no built-in function for this in JavaScript, but you can probably grab the decodeBase64 implementation from this website.
