AJAX data sources and multiple tokens

[andrewsnowden]

I've added some functionality that I needed, not sure if you'd like to pull these upstream.

You can fetch data remotely using an onFilterChanged callback and a setValues call. You can also specify a list of tokens to match (e.g. ["@", "#"]). I've added a demo for both of these functions in the demo.html

Thanks for that, you saved me.

Note that this code is not compatible with IE8, without changes. The forEach needs changing to a regular for loop, and you need some polyfills..

if (!Array.prototype.filter) {
  Array.prototype.filter = function(
     a, // a function to test each value of the array against. Truthy values will be put into the new array and falsy values will be excluded from the new array
    b, // placeholder
    c, // placeholder 
    d, // placeholder
    e  // placeholder
  ) {
      c = this; // cache the array
      d = []; // array to hold the new values which match the expression
      for (e in c) // for each value in the array, 
        ~~e + '' == e && e >= 0 && // coerce the array position and if valid,
        a.call(b, c[e], +e, c) && // pass the current value into the expression and if truthy,
        d.push(c[e]); // add it to the new array

      return d // give back the new array
  };
}

if (!Array.prototype.indexOf) {
  Array.prototype.indexOf = function (searchElement , fromIndex) {
    var i,
        pivot = (fromIndex) ? fromIndex : 0,
        length;

    if (!this) {
      throw new TypeError();
    }

    length = this.length;

    if (length === 0 || pivot >= length) {
      return -1;
    }

    if (pivot < 0) {
      pivot = length - Math.abs(pivot);
    }

    for (i = pivot; i < length; i++) {
      if (this[i] === searchElement) {
        return i;
      }
    }
    return -1;
  };
}

Also note the code is not compatible with jfelsinger's second token delimiter regexp workaround in #6. That's fine though, that was kind of a hack. The first token delimiter workaround (removing \b) still works.

Thanks, will try dig out a copy of IE8 and patch and test on that as soon as I get a chance

Oh, actually I assumed that this was a problem in your code, and I just realised it wasn't - it's an original 'bug' (incompatibility, really) in sew. Sorry for pinning it on you ;).

Why don't you accept this PR?
