The below JS function does Ajax request and retrieves HTML in obj.responseText
. My issue is that I need to extract the value of id
inside the span
into notify_id
var. I just don't know how to get that done.
This is the HTML to lookup:
HTML:
<span id="1034"></span><img src="./images/icons/post_icon.png">
JS:
function func()
{
obj = new XMLHttpRequest();
obj.onreadystatechange = function() {
if(obj.readyState == 4)
jQuery.jGrowl(obj.responseText, {
sticky:true,
close: function(e,m) {
notifyClosed(notify_id);
}
});
}
obj.open("GET", "notifications.php?n=1", true);
obj.send(null);
}
Since you're already using jQuery:
var responseText = '<span id="1034"></span><img src="./images/icons/post_icon.png">';
var spanId = $('<div>').html(responseText).find('span').attr('id');
alert(spanId); // 1034
The whole function in turn can also be rewritten as follows:
$.get('notifications.php?n=1', function(responseText) {
// Your code here.
});
