WSCurl Translate Language

[Benjamin Dasari]

Purpose:
Using WSCurl, input text in a non-Western language and then use a service such as Google Translate to change the text into English or some other language.

Liquid UI Code:

// SAPLSMTR_NAVIGATION.E0100.sjs
load('wscurl');

// Function to check if the string value is blank
function isBlank(jvar){
    if (jvar==void 0 || jvar=="" || jvar==null) {
        return true;
    }
    else {
        return false;
    }
}

/* Function is used to input text in a non-Western language and then use a service
   such as Google Translate to change the text into English or some other language */
function translate(param){   
   var z_text = param.toTranslate;
   var z_language = param.targetLang;
   
   /* Initialize the Curl object for making the call*/
   var wsCurl = new Curl();
   
   /* Fixed string to fetch data after translation from googleapis.com*/
   var baseURL = "https://www.googleapis.com/language/translate/v2?key=AIzaSyChzKkNGfmuBAhZXPD7Pw-1nl4e0c6shNw&q=";
   
   /* Say the text you want to convert is stored in variable "z_text", lets covert it to URI for web*/
   var textToConvert = encodeURI(z_text);
   
   /* Set source language identifier*/
   var sourceLangIdentifier = "&source=";
   
   /* Set source language (see language format below)*/
   var sourceLang = "en";
   
   /* Set translation language identifier*/
   var translateLangIdentifier = "&target=";
   
   /* Set translation language (see language format below)*/
   var translateLang = z_language;
