Post To Tumblr Version 0.4

Today is a small update day it seems.

I have updated my Post To Tumblr extension again. I was getting a couple of requests for the ability to add a 'caption' to a post before the image is uploaded so I cranked out this little feature. You can enable it in the options.

Once enabled rather than immediately posting the image it will popup a new tab allowing you to add a caption or whatever to your post:

Its not perfect, I would have preferred the pre formatting window to open in a div popup on the current page instead of a whole new tab, but for now this solution is simple and it works.

I must admit I borrowed the idea from another Tumblr posting extension called "Share on Tumblr". The code is ultra simple:

<html>
  <head>
    <script>
      // Thanks to share on tumblr extension for this
      chrome.tabs.getSelected(null, function (tab) {
        var url = getParam(tab.url, "u");
        //var url = encodeURIComponent(getParam(tab.url,"u"));
        var finalurl = "https://www.tumblr.com/share?v=3&amp;u=" + url + "&amp;s=";
        document.getElementById("container").src = finalurl;
      });

      // Thanks https://www.netlobo.com/url_query_string_javascript.html
      function getParam(url, name) {
        name = name.replace(/[[]/, "\[").replace(/[]]/, "\]");
        var regexS = "[\?&amp;]" + name + "=([^&amp;#]*)";
        var regex = new RegExp(regexS);
        var results = regex.exec(url);
        if (results == null) return "";
        else return results[1];
      }
    </script>
    <link rel="stylesheet" href="main.css" type="text/css" />
  </head>
  <body>
    <div id="header">
      <h1>Post To Tumblr</h1>
    </div>
    <div class="section-header first"><em>Format your post below</em></div>
    <br />
    <iframe id="container" style="width:500px;height:430px;border:0px" src=""></iframe>
  </body>
</html>

It just opens an iframe with the Tumblr Share page. Simples!
