617930 - WebInspector (Chrome, Safari): Error when printing the object in the console

Status: RESOLVED INVALID

(Other Applications Graveyard :: Narcissus, defect)

Build Identifier: 

When using WebInspector (Chrome, Safari), if you try to output the result of a parsing, it outputs this error:

Error: Node.prototype.length is gone; use n.children.length instead

This is because Web Inspector is accessing the length property to check if the object is an array. Then this triggers this code:

// jsparse.js line 261
definitions.defineGetter(Np, "length",
	function() {
	 throw new Error("Node.prototype.length is gone; " +
					 "use n.children.length instead");
	});


I believe that you added this code to easily make the transition. Is it over? Removing it would fix the issue.

Reproducible: Always

Steps to Reproduce:

1. Open this URL with Chrome: http://fooo.fr/~vjeux/blog/climbjs/optimize/test.html

2. Open WebInspector (Ctrl Alt Shift J)

3. Type:
Narcissus.parser.parse('')
Actual Results:  
Error: Node.prototype.length is gone; use n.children.length instead

Expected Results:  
> Node (You can click to see the actual object)
