For loop for object?

Solution 1
.length is a property of arrays, what you have is an object.
Try:
for(var key in options.commands) {
alert(options.commands[key].cmd);
}
Solution 2
Have a look at how-to-loop-through-javascript-object-literal-with-objects-as-members.
Essentially:
for (var key in options.commands) {
alert( options.commands[key].enabled );
...
}
Solution 3
for(var i in options.commands){
alert(i); //bold, italic, underline
alert(options.commands[i].cmd);
}

I have the next code in javascript. I deleted some unnecessary items because it went to long.
var options = { dhcode: true, commands: { bold: { enabled: true, view: true, exec: true, cmd: 'bold', param: null }, italic: { enabled: true, view: true, exec: true, cmd: 'italic', param: null }, underline: { enabled: true, view: true, exec: true, cmd: 'underline', param: null } } }
Now i want to get al data in the options.commands object. But everything what i try don't work. This is what i am trying:
for(var i=0;i<options.commands.length;i++) { alert(options.commands[i].cmd); }
Please help me.
