Variable and Object Names – Help

Copy linkTweet thisAlerts:
Apr 04.2006

I have the following issue:

I would like to access an object, but the object name is stored in a variable. How can I do this?

Example:

var mystr = “form1”;
document.{mystr}.object.attribute

I would like to access document.form1.object.attribute

The object itself is NOT a form. it’s a generic object.

I’ve used the collections before, but only with a position variable…

document.collection[2].object.attribute

but don’t know how to access by name. Is this possible? do I have to create an array of all my objects and positions so I reference them by position?

Thanks for all your help.

@A1ien51Apr 04.2006 — baisc idea:

document.forms[variableName].elements[elementName].value

@aeavaauthorApr 04.2006 — What you've said works under the browser environment. I am, however, working with Laszlo, so the structure is a bit different.

I was hoping for a more generic approach to it.

I have a collection named subnodes in my environment, equivalent to elements, I guess. I have this:

<view layout="axis:x" x="5" id="playfield">
<mybutton btext="*" />
<mybutton name="BAD" btext="BAD" />
<mybutton name="HHRD" btext="HHRD" />
<mybutton name="MAD" btext="MAD" />
<mybutton name="MBISD" btext="MBISD" />
<mybutton name="MSD" btext="MSD" />
<mybutton name="NSD" btext="NSD" />
<mybutton name="OD" btext="OD" />
<mybutton name="TAD" btext="TAD" />
</view>

I want to access, via javascript a particular object.

I can do "playfield.BAD.btext" and I would get the value for that attribute

I could also do "playfield.subnodes[2].btext" and I would get the same.

subnodes is not taking names, unfortunately, just position [#].

Success!
