Opening URL link when connecting via Liquid UI Server
« on: October 02, 2023, 12:09:56 PM »
Purpose:
Opening a URL link is different via direct connect and Liquid UI Server.
This article explains how to open links when connecting through a Liquid UI server.


Liquid UI Code:
----------------------------------------------------------------------------------------------------------------------------------------------
Script File Name: SAPLSMTR_NAVIGATION.E0100.sjs       // SAP Easy Access
----------------------------------------------------------------------------------------------------------------------------------------------
//================================================
// User Interface
//================================================
del("X[IMAGE_CONTAINER]");
pushbutton([4,1],"Open URL/Link via LUI Server","?",{"process":openURLviaServer});



//================================================
//Function Scripts
//================================================
// Function prototype to trim blank characters from a string
String.prototype.trim = function () {
   return this.replace(/^\s+|\s+$/g, "");
}

// Function to return trimmed string
function getString(strInput) {
   return (typeof(strInput) == 'undefined' || strInput == 'undefined') ? "" : strInput.toString().trim();
}

// Function to check for blank string
// Specifically used to determine if input exist in the edit field
function isBlank(strInput) {
   var strVal = getString(strInput);
   var blank = strVal == "";
   return blank;
}

//Function to delete toolbar buttons on popup
function delButtonsRSM0400() {
   del('P[Continue]');
   del('P[Generate]');
   del('P[End Session]');
   del('P[Cancel]');
   if(<'P[Delete Session]'>.isValid)      del("P[Delete Session]");
}

//Function to display Liquid UI message popup
function procLUIMessageBox(param){
   var intHeight = 5 + 4 + param.l_message.length;
   var intPaintRow = 1;
   var intPaintCol = 3;
   enter("/o");
               
   onscreen 'RSM04000_ALV_NEW.2000'
      goto RESIZE_REPAINT;

            text([intPaintRow+idxI,intPaintCol+4], param.l_message[idxI]);
         else
            text([intPaintRow+idxI,intPaintCol], param.l_message[idxI]);
      }
      intWidth = intWidth+20;
