there a reason why this isn't working?

JAVASCRIPT Code: [ Select ]
$.ajax({
    url: "js/img3.xml",type: 'GET',dataType: 'xml',timeout: 1000,error: function(){alert('Error loading XML document');},
    success: function(xml) {
       var source = $(this).find('image[source]').text(this);
       var desc = $(this).find('image[description]').text(this);
       var category = $(this).find('image[id]').text(this);
       var index = $(this).index(this);
         $(this).find('image').each(function(){
             $("#textcontainer").append('<p>' + desc + '</p>');
         });
    }
});
 
  1. $.ajax({
  2.     url: "js/img3.xml",type: 'GET',dataType: 'xml',timeout: 1000,error: function(){alert('Error loading XML document');},
  3.     success: function(xml) {
  4.        var source = $(this).find('image[source]').text(this);
  5.        var desc = $(this).find('image[description]').text(this);
  6.        var category = $(this).find('image[id]').text(this);
  7.        var index = $(this).index(this);
  8.          $(this).find('image').each(function(){
  9.              $("#textcontainer").append('<p>' + desc + '</p>');
  10.          });
  11.     }
  12. });
  13.  


It's not generating anything in my html, at all.

You're not really inside an object operator when you start that bit of code, so I'm not sure $(this) would refer to a valid object at that point. Have you tried outputting anything on source/desc/category/index to make sure they're getting the expected values? I'm pretty sure your selector just as you step into the success callback would have to be $(xml).find() etc. etc.

Here's an example from an IBM tuto I came across when verifying my thought:
Code: [ Select ]
success: function(xml){
  $(xml).find('item').each(function(){
    var item_text = $(this).text();

    $('<li></li>')
      .html(item_text)
      .appendTo('ol');
  });
}
  1. success: function(xml){
  2.   $(xml).find('item').each(function(){
  3.     var item_text = $(this).text();
  5.     $('<li></li>')
  6.       .html(item_text)
  7.       .appendTo('ol');
  8.   });
  9. }
I'd love to change the world, but they won't give me the source code.

so then this should work, and yet it is not,

JAVASCRIPT Code: [ Select ]
$.ajax({
    url: "js/img3.xml",type: 'GET',dataType: 'xml',timeout: 1000,error: function(){alert('Error loading XML document');},
    success: function(xml) {
         $(xml).find('image').each(function(){
      var source = $(this).attr('source').text(this);
      var desc = $(this).attr('description').text();
      var category = $(this).attr('id').text();
      var index = $(this).index(this);
                      $("#textcontainer").append('<p>' + desc + '</p>');
          $("#webthumblist").append('<li><a id="' + index + '"></a>');
          $("#imagecontainer").append('<img src="' + source + '" />');
         });
    }
});
 
  1. $.ajax({
  2.     url: "js/img3.xml",type: 'GET',dataType: 'xml',timeout: 1000,error: function(){alert('Error loading XML document');},
  3.     success: function(xml) {
  4.          $(xml).find('image').each(function(){
  5.       var source = $(this).attr('source').text(this);
  6.       var desc = $(this).attr('description').text();
  7.       var category = $(this).attr('id').text();
  8.       var index = $(this).index(this);
  9.                       $("#textcontainer").append('<p>' + desc + '</p>');
  10.           $("#webthumblist").append('<li><a id="' + index + '"></a>');
  11.           $("#imagecontainer").append('<img src="' + source + '" />');
  12.          });
  13.     }
  14. });
  15.  


this is what my xml looks like:

XML Code: [ Select ]
<root>
      <image
         source="tadesign/images/carcare.jpg"
         description="Description text goes here about carcaredetail"
         id="web"
      />
     
      <image
         source="tadesign/images/monster.jpg"
         description="Description text goes here about monster resolution"
         id="web"
      />
     
      <image
         source="tadesign/images/rantingbill.jpg"
         description="Description text goes here about rantingbill"
         id="web"
      />
     
      <image
         source="tadesign/images/voltecsite.jpg"
         description="Description text goes here about voltec design"
         id="web"
      />
</root>
 
  1. <root>
  2.       <image
  3.          source="tadesign/images/carcare.jpg"
  4.          description="Description text goes here about carcaredetail"
  5.          id="web"
  6.       />
  7.      
  8.       <image
  9.          source="tadesign/images/monster.jpg"
  10.          description="Description text goes here about monster resolution"
  11.          id="web"
  12.       />
  13.      
  14.       <image
  15.          source="tadesign/images/rantingbill.jpg"
  16.          description="Description text goes here about rantingbill"
  17.          id="web"
  18.       />
  19.      
  20.       <image
  21.          source="tadesign/images/voltecsite.jpg"
  22.          description="Description text goes here about voltec design"
  23.          id="web"
  24.       />
  25. </root>
  26.  


must I use this "appendTo" now that I'm dealing with attributes of my xml tags?

web dev is telling me that:


Quote:
var source = $(this).attr('source').text is not a function



what does this mean? Of course it's not a function, it's a variable...

can you use the attributeHas selector on "this"...
like so:

JAVASCRIPT Code: [ Select ]
var source = $(this[id='web']).attr('source');
 
  1. var source = $(this[id='web']).attr('source');
  2.  


I only want to get the "source" if the "id" attribute is "web"
It's not working so far, returns the string "undefined" instead of the "source" text.
