printObj() => outputs object properties

The javascript function below is used to output the objects and its properties. Alternative to the php function => print_r

I use it mostly for looking up the document DOM eg. printObj(document)

Insert code inside JavaScript <script> tags

_________________________________________________

function printObj(obj) //reads the objects properties

{

var object ="";// sets the variable

for(var type in obj)

{object += type +"=> " + obj[type] + "<br /> ";}

document.write(object);

}

//create a new array or object

var num = new Array(1,2,3,45,6);

//outpuy the object and its properties by

printObj(num)

______________________________________________

Output:

0=> 1
1=> 2
2=> 3
3=> 45
4=> 6

bookmarklet: shows all the the p tags for the page. Copy and paste the code below in the address bar.

javascript:e = document.getElementsByTagName('p');function printObj(obj){var object ="";for(var type in obj){object += type +"=> " + e[type].innerHTML + "<br />";}document.write(object);}printObj(e);
