type and property name. If an object property can't be accessed, an error message will be shown.Here the snippets for inspect javascript object.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;}Method Call:function inspect(obj [, maxLevels [, level]]) Input Vars * obj: Object to inspect * maxLevels: Optional.
