The utilization of the $.ajax() function to retrieve data from a remote URL

My task involves reading this remote XML file: , in an HTML file using Ajax! This is the code I have written:

<script type="text/javascript">

getReadXmlFile();

function getReadXmlFile(){
    alert("Searching for file");
    $.ajax({
        type: "GET",
        url: "http://www.velib.paris/service/stationdetails/paris/901",
        dataType: "xml",
        success: parseXml
    });
    alert("Obtaining file");
}

function parseXml(xml){
    alert('Parsing started');
    var up = $(xml).find("updated").text();
    alert(up);
}        
</script>

Unfortunately, it's not working and I don't know why. Thank you for your help! I really need assistance!

Answer №1

I tested out your code on JSFiddle (with some unrelated modifications) and it seems to be functioning correctly.

getReadXmlFile();

function getReadXmlFile(){
  alert("searching for file");
  $.ajax({
    type: "POST", // The use of POST method is specific to JSFiddle, unrelated to the issue
    url: "/echo/xml/",
    dataType: "xml",
    data: {
      xml: `
        <?xml version="1.0" encoding="utf-8"?>
        <station>
          <available>1</available>
          <free>19</free>
          <total>20</total>
          <ticket>1</ticket>
          <open>1</open>
          <updated>1472183109</updated>
          <connected>1</connected>
         </station>
      `
    },
    success: parseXml
  });
  alert("file obtained");
}

function parseXml(xml){
  alert('starting to parse');
  var up=$(xml).find("updated").text();
  alert(up);
}
