Creating a script to open multiple URLs in HTML and JavaScript

Currently, I am working on creating a multiple URL opener using HTML and JavaScript. However, I have encountered an issue where HTTP links are opening fine but HTTPS links are not. Can someone provide assistance with this problem? Below is the code snippet.

function open_all() {
  var urls = document.getElementById("list_urls").value;
  var urls = urls.split('\n');
  var totalno = urls.length;
  var s;
  for (var i = 0; i < totalno; i++) {
    s = urls[i];
    if (s) {
      if (s.substr(0, 7) != 'http://') {
        s = 'http://' + s;
      }
      window.open(s);
    }
  }
  return false;
}

<form method="post" action="">
  <br />
  <textarea name="list_urls" id="list_urls" cols="60" rows="20"></textarea>
  <br />
  <br />
  <input value="Open URLs" class="submit" type="button" onClick="open_all();">
  <br />
  <input type="reset" value="Reset!">
  <br/>
</form>

Any help would be greatly appreciated!

Answer №1

The problem arises from the current code where http:// is added to URLs that start with https://. To resolve this, the logic needs to be adjusted to check for both https:// and http:// at the beginning of the URL. Additionally, the logic can be streamlined by using trim() to ensure there are no extra spaces in the line. See the revised code below:

function open_all() {
    var urls = document.getElementById("list_urls").value.split('\n');
    for (var i = 0; i < urls.length; i++) {
        var url = urls[i];
        if (url.trim()) {
            if (s.substr(0,7) != 'http://' && s.substr(0,8) != 'https://') 
                url = 'http://' + url;
            window.open(url);
        }
    }
    return false;
}

It's worth noting that your browser's popup blocker might interfere with opening multiple windows rapidly.

Ensure to include some additional logic in your if statement for the presence of "https-"

if(s.substr(0,7)!='http://' && s.substr(0,7)!='https:/')
