Question

How do I get the phrase number from the phrase object using the parseInt() function? I tried to create the function within the swapFE function in var phrasenum below but it did not work. I think my values are wrong. What should I put there instead? Any help would be greatly appreciated. Thanks in advance! The following is the french phrase number (1-10 or in JavaScript 0-9) and the french an english phrases to be used:

> var english=new Array();
english[0]="This hotel isn't far from the Eiffel Tower.";
english[1]="What time does the train arrive?";
english[2]="We have been waiting for the bus for one half-hour.";
english[3]="This meal is delicious";
english[4]="What day is she going to arrive?";
english[5]="We have eleven minutes before the train leaves!";
english[6]="Living in a foreign country is a good experience.";
english[7]="Excuse me! I'm late!";
english[8]="Is this taxi free?";
english[9]="Be careful when you go down the steps.";

var french=new Array();
french[0]="Cet hôtel n'est pas loin de la Tour Eiffel.";
french[1]="A quelle heure arrive le train?";
french[2]="Nous attendons l'autobus depuis une demi-heure.";
french[3]="Ce repas est délicieux";
french[4]="Quel jour va-t-elle arriver?";
french[5]="Nous avons onze minutes avant le départ du train!";
french[6]="Habiter dans un pays étranger est une bonne expérience.";
french[7]="Excusez-moi! Je suis en retard!";
french[8]="Est-ce que ce taxi est libre?";
french[9]="Faites attention quand vous descendez l'escalier.";

Here are the functions I am working on:

function setUpTranslation() {
   var phrases = document.getElementsByTagName("p");

   for (i = 0; i<phrases.length; i++) {
      phrases[i].number = i;
      phrases[i].childNodes[1].innerHTML = french[i];

      phrases[i].childNodes[1].onmousedown = function() { swapFE(event); }; 
  }

}

function swapFE(e) {
       var phrase = e.srcElement; 

       var phrasenum = parseInt(phrase[1].childNodes[1].innerText);

       alert("French Number = "+phrasenum+"Phrase = "+phrase.childNodes[1]);
}

This is the answer I came up with and it worked. See var phrasenum. Thanks for all your help guys!

//this function changes the French phrase to an English phrase.
    function swapFE(e) {
           var phrase = e.srcElement; 
           //phrase.innerText = english[phrase.id];
           var parent = phrase.parentNode;
           //childNodes[0] is the number of the phrase +1 
           var idnum = parent.childNodes[0];
           //parseInt takes a textstring and extracts it to make a number. Then you will subtract 1 from the number.
           var phrasenum = parseInt(idnum.innerHTML)-1;
           phrase.innerText = english[phrasenum];


  }


function swapEF(e) {
       var phrase = e.srcElement; 
       //phrase.innerText = english[phrase.id];
       var parent = phrase.parentNode;
       var idnum = parent.childNodes[0];
       var phrasenum = parseInt(idnum.innerHTML)-1;
       phrase.innerText = french[phrasenum];

}
