xmlHTTPrequest won't open ("GET" , url, true); I'm miffed! PHP
Solution 1
In your response function, do you mean to check .status == 4 instead of .readyState?
Solution 2
According to this, XMLHttpRequest.open() has no return value, so your check will always fail.

I've been trying to get a url to open but I'm miffed as to why this hasn't worked. The code is listed and explained below. Any help will be deeply appreciated.
The object:
function getXMLHTTPRequest() { var req = false; try { /* for Firefox */ req = new XMLHttpRequest(); } catch (err) { try { /* for some versions of IE */ req = new ActiveXObject("Msxml2.XMLHTTP"); } catch (err) { try { /* for some other versions of IE */ req = new ActiveXObject("Microsoft.XMLHTTP"); } catch (err) { req = false; } } } return req; }
The object is called like this:
<script type="text/javascript"> var myDelete = new getXMLHTTPRequest(); </script>
Now here's what I want to do:
function removeArticle(id) { if (myDelete) { try { var deletUrl = "delete.php"; var query = deletUrl + "?theid=" + id; myDelete.open("GET", query, true); myDelete.onreadystatechange = removeArticleResponse; myDelete.send(null); } catch (e) { alert ("Unable to connect to the server:\n" + e.toString()); } } else { alert ("Bad! Very BAD!"); } }
When I do this:
if (myDelete.open("GET", query, true)) { myDelete.onreadystatechange = removeArticleResponse; myDelete.send(null); } else { alert ("No road!"); }
The alert("No road!"); shows me that the code doesn't execute passed this point:
if (myDelete.open("GET", query, true)) {
This means that the if (myDelete) { works. The code passes this stage and for some reason stops here: myDelete.open("GET", query, true); It won't open the url. I'm not sure what the problem is.
Edit: Here's the function used to access the server response:
function removeArticleResponse () { if (myDelete.status == 4) { if (myDelete.status == 200) { try { response = myDelete.responseText; document.getElementById('displaynewsletterarticleresult').innerHTML = response; } catch(e) { alert("An error occured while reading the response:" + e.toString()); } } else { alert ("An error occured when attempting to retrieve the data:\n" + myDelete.statusText); } } }
