Question

I hope that someone will know how to help me with this problem, I am new to javaScript and XML. Basically I have the xml file with list of products, I have managed to dynamically load the data into an ul li list in my html page, the li elements has title and image, and now I need to be able to click on this li element and load remaining data for a specific product into a new page (or div). I am getting the “Uncaught ReferenceError: i is not defined” My question is how could I load the correct remaining data after clicking on a specific product from the list of products. (I hope that my explanation is clear enough) here is my code, the first function produces the ul li list in the html page, the displayPRInfo() function should load the data into showPrInfo div for any product which was clicked.

please help me, any help appreciated , thanks for reading.

function loadProducts() {
var liOpen=("<li onclick='displayPRInfo(" + i + ")'><p>");
      var divOpen=("</p><div class='prod-sq-img'>");  
      var closingTags=("</div></li>");
    var txt;
    var image;
    var title;


    var x=xmlDoc.getElementsByTagName("product");
    for (i=0;i<x.length;i++)
      { 
      title=(x[i].getElementsByTagName("title")[0].childNodes[0].nodeValue);
      image=(x[i].getElementsByTagName("imgfile")[0].childNodes[0].nodeValue);
      txt=  liOpen +  title + divOpen + image + closingTags ;
      document.getElementById("ulList").innerHTML+=txt;
      }

    }
        function displayPRInfo(i)
{
title=(x[i].getElementsByTagName("title")[0].childNodes[0].nodeValue);
euPriceRet=(x[i].getElementsByTagName("euror")[0].childNodes[0].nodeValue);
euPriceTrade=(x[i].getElementsByTagName("eurot")[0].childNodes[0].nodeValue);
euPriceSet=(x[i].getElementsByTagName("eset")[0].childNodes[0].nodeValue);
minimumQuantity=(x[i].getElementsByTagName("mqty")[0].childNodes[0].nodeValue);
description=(x[i].getElementsByTagName("desc")[0].childNodes[0].nodeValue);
prBigImg=(x[i].getElementsByTagName("pimgfile")[0].childNodes[0].nodeValue);
prInfo=title+"<br>"+euPriceRet+"<br>"+euPriceTrade+"<br> "+euPriceSet+"<br> "+minimumQuantity+"<br>"+description+"<br>"+ prBigImg ;
document.getElementById("showPrInfo").innerHTML=prInfo;
}

You can use jQuery to manipulate xml and set onclick events.

function loadProducts() {
    var products = $(xmlDoc).find('product');

    for (var i = 0; i < products.length; i++) {
      $('#ulList').append('<li id="product_' + i + '"><p>' + $(products[i]).find('title').text() + '</p><div class="prod-sq-img">' + $(products[i]).find('imgfile').text() + '</div></li>');
      $('#product_' + i).click(displayPRInfo.bind($('#product_' + i), products[i]));
    }
 }

function displayPRInfo(xmlProduct) {
  var title= $(xmlProduct).find('title).text();
  var euPriceRet = $(xmlProduct).find('euror').text();
  var euPriceTrade = $(xmlProduct).find('eurot').text();
  var euPriceSet = $(xmlProduct).find('eset').text();
  var minimumQuantity = $(xmlProduct).find('mqty').text();
  var description = $(xmlProduct).find('desc').text();
  var prBigImg = $(xmlProduct).find('pimgfile').text();
  var prInfo = title+"<br>"+euPriceRet+"<br>"+euPriceTrade+"<br> "+euPriceSet+"<br> "+minimumQuantity+"<br>"+description+"<br>"+ prBigImg ;
  $('#showPrInfo').html(prInfo);
}
