Javascript dump variable

Понеделник, 23 Ноември 2009 23:09:50

Few lines of javascript that will dump objects:

	function print_r(variable) {
		var out = ''; 
		if (typeof variable == 'object') {
			out = "[n";
			for (var k in variable) {
				out += ' ' + k + ' => ' + print_r(variable[k]) + "n";
			}
			out += ']';
		} else {
			out = variable;
		}
		return out;
	}

Here is how to test it: alert(print_r([1, 2, 3, {type : 'test', 2: 'adf'}])); Or even better:

	function print_r(variable, depth) {
		var out = ''; 
		if (!depth) depth = 1;
		if (typeof variable == 'object') {
			out = "[n";
			for (var k in variable) {
				for (var i=0; i<depth; i++)
					out += "t";
				out += '[' + k + '] => ' + print_r(variable[k], depth+1) + "n";
			}
			for (var i=0; i<depth-1; i++)
				out += "t";
			out += ']';
		} else {
			out = '"' + variable + '"';
		}
		return out;
	}
