jQuery Input Text Replacement

Thought I’d save this handy dandy function for later.
Makes the text in an input disappear when you click on the input.

// the function:

function textReplacement(input){

 var originalvalue = input.val();

 input.focus( function(){

  if( $.trim(input.val()) == originalvalue ){ input.val(''); }

 });

 input.blur( function(){

  if( $.trim(input.val()) == '' ){ input.val(originalvalue); }

 });

}

// how to use:

textReplacement($('#inputname'));

Example:

Find Anchors

Handy little function … finds an anchor and returns its text, or returns false.

function findAnchor(){

    var url = document.location.toString();

    if( url.match('#') ){

        return url.split('#')[1];

    } else {

        return false;

    }

}

JS Object Iterator

Extremely handy when you’re dealing with an Object and have no idea what it’s methods or properties are. ESPECIALLY when there’s no documentation and you get an alert saying [Object] or whatever.

function deconstruct(what){

    obj = eval(what);

    var temp = "";

    for (x in obj)

            temp += x + ": " + obj[x] + "\n";

    alert (temp);

}

I wish I remember the source for this because it has to be one of the handiest functions ever.
