j'ai un probleme avec le code suivant :
Code : Tout sélectionner
addLoadEvent(
93 function()
94 {
95 var element = document.getElementById('modify_topic_select_submit');
96 element.type = 'button';
97 element.onclick = function() {
98 element = this;
99 this.disabled = 'disabled';
100 document.getElementById('modify_topic_select').disabled = 'disabled';
101 this.value = 'Veuillez patienter...';
102 var xhr = new XMLHttpRequest();
103 xhr.onreadystatechange = function() {
104 if(xhr.readyState == 4)
105 {
106 if(xhr.status == 200)
107 {
108 document.getElementById('modify_topic_order').disabled='disabled';
109 element.parentNode.removeChild(element);
110 fieldsetFieldsSwitchDisplay('modify_topic');
111
112 var topic = xhr.responseXML.getElementsByTagName('topic');
113 topic = topic[0];
114
115 document.getElementById('modify_topic_title').value = topic.getElementsByTagName('title')[0].firstChild.data;
116 document.getElementById('modify_topic_contents').value = topic.getElementsByTagName('contents')[0].firstChild.data;
117
118 var topicImageArea = document.createElement('p');
119 var topicImage = document.createElement('img');
120 topicImage.src = '../../encyclopedie/images/topics/' + topic.getElementsByTagName('id')[0].firstChild.data + '.gif';
121 topicImage.alt = '';
122 topicImageArea.appendChild(topicImage);
123 document.getElementById('modify_topic_fields').insertBefore(topicImageArea, document.getElementById('modify_topic_order').parentNode)
124
125 selectOrder = document.getElementById('modify_topic_order');
126 selectOrder.removeChild(selectOrder.firstChild.nextSibling);
127
128 var xhrorder = new XMLHttpRequest();
129 xhrorder.onreadystatechange = function()
130 {
131 if(xhrorder.readyState == 4)
132 {
133 if(xhrorder.status == 200)
134 {
135 selectOrder = document.getElementById('modify_topic_order');
136 selectOrder.removeChild(selectOrder.firstChild.nextSibling);
137
138 var topics = xhrorder.responseXML.getElementsByTagName('topic');
139
140 newOption = document.createElement('option');
141 newOption.value = '1';
142 selectOrder.appendChild(newOption.appendChild(document.createTextNode('Au début')));
143
144 for(var i = 0; line = topics[i]; i++)
145 {
146 newOption = document.createElement('option');
147 newOption.value = line.lastChild.firstChild.data + 1;
148 optionText = document.createTextNode(line.firstChild.firstChild.data);
149 newOption.appendChild(optionText);
150 selectOrder.appendChild(newOption);
151 }
152 selectOrder.removeAttribute('disabled');
153 }
154 }
155 };
156 xhrorder.open = ('GET', 'includes/javascript/ajax.xml?action=1&cat_id=4' + topic.getElementsByTagName('cat_id')[0].firstChild.data, true);
157 xhrorder.send(null);
158 }
159 }
160 };
161 xhr.open('GET', 'includes/javascript/ajax.xml?action=2&topic_id=' + document.getElementById('modify_topic_select').value, true);
162 xhr.send(null);
163 }
164 }
165);
[Exception... "Component returned failure code: 0xc1f30001 (NS_ERROR_NOT_INITIALIZED) [nsIXMLHttpRequest.send]" nsresult: "0xc1f30001 (NS_ERROR_NOT_INITIALIZED)" location: "JS frame :: anonymous :: line 157" data: no]
J'ai essayé de changer pas mal de chose dans le code mais rien y fait...
si vous avez une idée,
merci,
