Find element by iterating through all the available TargetValues in a Queue using DeQueue

[Nagendra Kuppala]

Hello,

Need quick help on queue and DeQueue in JS.

I'm trying to pass the working Target Element to a doCommand() function which executes the step with Command, CommandTarget and Value.

var targetValue = "";
function passTarget(cmd){
    let targetStr = getTarget(cmd);     //Example targetStr = id=btn_basic_example; link=Start Practising; css=#btn_basic_example; xpath=//a[contains(text(),'Start Practising')]; xpath=//div[@id='home']/p[2]/a; xpath=//p[2]/a
    let commandTargetStr = targetStr.split(";");      
    let q = new Queue();
    for(var i =0; i<commandTargetStr.length; i++){
        q.add(commandTargetStr[i]);
    }    
    // If the Target queue has only one value, return the TargetValue to doCommand to execute.
    if (commandTargetStr.length === 1) {
        targetValue = commandTargetStr;
        ctri_log.info("targetValue :" + targetValue);
        return;
    }
   
    q.data = q.data.reverse();
    ctri_log.info(q.data);    // Output Queue: id=btn_basic_example,link=Start Practising,css=#btn_basic_example,xpath=//a[contains(text(),'Start Practising')],xpath=//div[@id='home']/p[2]/a,xpath=//p[2]/a
   
    // pass first element from the queue to selectValidTarget().
    // poll()-Removes and returns the head of the queue. Returns null if queue is empty.
    // Lets say Top:
    targetValue = q.poll();   // Not Working , [error] TypeError: q.poll is not a function  
}


function selectValidTarget(targetValue) {
    try {


            ctri_log.info("targetValue: " + targetValue);
            ctri_log.info(targetValue +" value =  " + $(targetValue.split('=')[1]));
            ctri_log.info(targetValue +" length =  " + $(targetValue.split('=')[1]).length);
           
            // Check if element is present or not in a web page. If present pass Target element to doCommand ();
            if(targetValue.startsWith('xpath')){
              if($x(targetValue.split('=')[1]).length == 1 ){
                    break;
              }else if($(targetValue.split('=')[1]).length == 1 ){
                    break;
               }else if{ q.poll().isNotEmpty()){
                        GOTO Top: ;
              }else{
                    Fail; // Pass First Target element to doCommand ();
            }        
    } catch (e) {
        console.error(e);
    }
}




function doCommand() {
    let commands = getRecordsArray();
    let commandName = getCommandName(commands[currentPlayingCommandIndex]);
    passTarget(commands[currentPlayingCommandIndex]); //getCommandTarget(commands[currentPlayingCommandIndex]);
    let commandTarget = targetValue;
    let commandValue = getCommandValue(commands[currentPlayingCommandIndex]);
   
    execute();
}

I basically looking for something like this:

TOP:
Let x = deque[q.data];

find(){
          if ( found){
                   exit; // Check if element is present or not in a web page. If present pass Target element to doCommand ();
          }else if(x Not Empty){   // if Queue not empty re-iterate
                   GOTO TOP: ;
          }else{         // if Queue empty.
                   Fail; // Pass First Target element to doCommand ();
          }

function doCommand() {
    let commands = getRecordsArray();
    let commandName = getCommandName(commands[currentPlayingCommandIndex]);
    passTarget(commands[currentPlayingCommandIndex]); //getCommandTarget(commands[currentPlayingCommandIndex]);
    let commandTarget = targetValue;
    let commandValue = getCommandValue(commands[currentPlayingCommandIndex]);
   
    execute();
}
