I found this sample code where i can replace something automatically in the page
// If content-type is HTML, then remove all DIV tags
if (oSession.oResponse.headers.ExistsAndContains("Content-Type", "html")){
// Remove any compression or chunking
oSession.utilDecodeResponse();
var oBody = System.Text.Encoding.UTF8.GetString(oSession.responseBodyBytes);
// Replace all instances of the DIV tag with an empty string
var oRegEx = /<div[^>]*>(.*?)<\/div>/gi;
oBody = oBody.replace(oRegEx, "");
// Set the response body to the div-less string
oSession.utilSetResponseBody(oBody);
}
But how can i ask for the new value, instead of replacing it automatically?
See if this works for you
OnBeforeResponse
