Question

if(properties != undefined)
{
    foreach(key in properties)
    {
        dialogProperty.key = property[key];
    }
    alert(dialogProperty.close);
}

How can I achieve/fix the above code? I think the above code is self explanatory.

Answer 1

I think you mean for rather than foreach. You should also stop key being global and use Object.prototype.hasOwnProperty:

if(properties != undefined)
{
    for (var key in properties)
    {
        if (properties.hasOwnProperty(key) {
            dialogProperty[key] = properties[key]; // fixed this variable name too
        }
    }
    alert(dialogProperty.close);
}

NB Incorporated Kobi’s fix too.
