jQuery如何通过ajax方式定时读取xml文件并分析。
xml文件如下:
<?xml version="1.0"?>
<data>
<page tasks="1" messages="3" notifications="3"/>
</data>
js文件如下:
$(document).ready(function() {
function get_info() {
$.ajax({
type: "GET",
url: "page.xml",
dataType: "xml",
cache: false,
complete: function(doc) {
var tasks = $(doc.responseText).find("page").attr("tasks");
var msgs = $(doc.responseText).find("page").attr("messages");
var notes = $(doc.responseText).find("page").attr
("notifications");
if (tasks != $('#tasks').text() ||
msgs != $('#messages').text() ||
notes != $('#notifications').text()) {
document.title = "Facebook" + ' NEW NOTIFICATON';
}
$('#tasks').text(tasks);
$('#messages').text(msgs);
$('#notifications').text(notes);
}
});
}
setInterval(function() {
get_info();
}, 5000);
});
