[jQuery] Re: Convert to jQuery

[Yehuda Katz]

function resize(which, max) {
 var elem = document.getElementById(which);
 if (elem == undefined || elem == null) return false;
 if (max == undefined) max = 100;
 if (elem.width >  elem.height) {
   if (elem.width > max) elem.width = max;
 } else {
   if (elem.height > max) elem.height = max;
 }
}

becomes

$.fn.resize = function(max) {
  max = max || 100;
  this.each(function() {
    if(this.width > this.height && this.width > max) this.width = max;
    else if(elem.height > max) elem.height = max;
  });
};


and you'd call it as $().resize(max);

Eventually, you'll do something like:

$(document).ready(function() {
  $("input selector").blur(function() { $("thing to resize").resize(max) });
});
