Javascript - Debugging Javascript as PHP / Function var_dump

/ Published in: JavaScript

In javascript there is no function for printing variables like you have PHP, I use print_r and var_dump a lot in PHP for dumping variables
so I wanted to create a simular function in javascript.

Expand | Embed | Plain Text

Copy this code and paste it in your HTML

function var_dump( objElement, intLimit, intDepth )
{
	intDepth = intDepth?intDepth:0;
	intLimit = intLimit?intLimit:1;
 
	strReturn = '<ol>';
 
	for( property in objElement )
	{
		// Property domConfig isn't accesible
		if( property != 'domConfig' )
		{
			strReturn += '<li><strong>' + property + '</strong> <small>(' + ( typeof objElement[property] ) + ')</small>';
 
			if ( typeof objElement[property] == 'number' || typeof objElement[property] == 'boolean' ) {
				strReturn += ' : <em>' + objElement[property] + '</em>';
			}
 
			if ( typeof objElement[property] == 'string' && objElement[property] ) {
				strReturn += ': <div style="background:#C9C9C9; border:1px solid black; overflow:auto;"><code>' +
								objElement[property].replace(/</g, '&lt;').replace(/>/g, '&gt;') + '</code></div>';
			}
 
			if ( typeof objElement[property] == 'object' && ( intDepth < intLimit ) ) {
				strReturn += var_dump( objElement[property], intLimit, ( intDepth + 1 ) );
			}
 
			strReturn += '</li>';
		}
	}
 
	strReturn += '</ol>';
 
	if ( intDepth == 0 )
	{
		winpop = window.open( "", "", "width=800, height=600, scrollbars, resizable" );
		winpop.document.write( '<pre>' + strReturn + '</pre>' );
		winpop.document.close();
	}
 
	return strReturn;
}
