JavaScript Snippet – getAbsPathFor()

Mission & Code

Sometimes you just need a way of determining the absolute path from a specified relative path. When you are in this situation, you may use the following code:

(function() {
  var img = new Image();
  getAbsPathFor = function(relativePath) {
    img.src = relativePath;
    return img.src;
  };
})();

Parameters

1. relativePath:
   The relative (as a string) that you would like to retrieve the corresponding absolute path for.

Example

To use this code, you could do something similar to the following:

// Show me the absolute path for "../".
alert('The absolute path for "../" is "' + getAbsPathFor('../') + '".');

// Show me the absolute path for "/test/".
alert('The absolute path for "/test/" is "' + getAbsPathFor('/test/') + '".');

Final Notes

This code is only for web browser, and/or HTA use. This code probably won’t work in a stand-alone desktop JScript.
