IntroductionThis is a useful tool whenever you work with JavaScript and the compatibility issues between navigators. You can inspect any JavaScript objects and list them as indented, ordered by levels. Using the Codefunction inspect(obj [, maxLevels [, level]])
Input Vars
Return ValueHTML formatted function inspect(obj, maxLevels, level)
{
var str = '', type, msg;
// Start Input Validations
// Don't touch, we start iterating at level zero
if(level == null) level = 0;
// At least you want to show the first level
if(maxLevels == null) maxLevels = 1;
if(maxLevels < 1)
return '<font color="red">Error: Levels number must be > 0</font>';
// We start with a non null object
if(obj == null)
return '<font color="red">Error: Object <b>NULL</b></font>';
// End Input Validations
// Each Iteration must be indented
str += '<ul>';
// Start iterations for all objects in obj
for(property in obj)
{
try
{
// Show "property" and "type property"
type = typeof(obj[property]);
str += '<li>(' + type + ') ' + property +
( (obj[property]==null)?(': <b>null</b>'):('')) + '</li>';
// We keep iterating if this property is an Object, non null
// and we are inside the required number of levels
if((type == 'object') && (obj[property] != null) && (level+1 < maxLevels))
str += inspect(obj[property], maxLevels, level+1);
}
catch(err)
{
// Is there some properties in obj we can't access? Print it red.
if(typeof(err) == 'string') msg = err;
else if(err.message) msg = err.message;
else if(err.description) msg = err.description;
else msg = 'Unknown';
str += '<li><font color="red">(Error) ' + property + ': ' + msg +'</font></li>';
}
}
// Close indent
str += '</ul>';
return str;
}
