[patch] FilteringSelect: newlines in inline data not trimmed

[[email protected]…]

I study along with The Dojo Book and program in the MyEclipse?. I learn Example 2 - The Postman Always Clicks Twice. When I program FilteringSelect?, the problem occured. At first, my code is: <select id="option1" dojoType="dijit.form.FilteringSelect?">

<option value="pop3">POP3</option> <option value="imap">IMAP</option>

</select> It has work well. But when I format using MyEclipse?'s Format functionality, my code changes to: <select id="option1" dojoType="dijit.form.FilteringSelect?">

<option value="pop3">

POP3

</option> <option value="imap">

IMAP

</option>

</select> It doesn't work well. Note: Carriage Return appear alongside "POP3" and "IMAP". I guess this is a bug of Dojo 1.0.0. Because of I'm a Chinese, I don't be easy to login in this web site. Whether this is a bug or not, please notify me using Email. Thanks a lot. My email address: [email protected]…

Changing bug summary to be more descriptive than "doesn't work". Note that every ticket is about something that doesn't work.

Looks like a simple fix to dijit.form._ComboBoxDataStore.

I am also getting this behavior with dojo.data. In states.json, if you write:

	{name:"\nAlaska\n", label:"Alaska",abbreviation:"AK"},

Alaska will vanish from the ComboBox? list (dojo.data does not return it in the result list). The item is in the store, but even a query for '*' does not match it.

I say this because I noticed a mixin to our store I don't remember:

//Mix in the simple fetch implementation to this class. 
dojo.extend(dijit.form._ComboBoxDataStore,dojo.data.util.simpleFetch);

So maybe if we can figure this out for dojo.data the rest will follow.

Hmm, that does sound like a bug in the dojo.data library functions, but regardless of that, it seems like if a developer accesses an item from ComboBoxDataStore (perhaps by accessing ComboBox.item), it would be bad for it to contain newlines like:

{name:"\nAlaska\n", label:"Alaska",abbreviation:"AK"}

I just figured we should trim the data from each <option> tag.

Fixes #6469. Strip option tags of newlines; users usually don't intend for them to be there.

Refs #6469. Enable dojo.data to match against values containing newline characters.

[haysmark]

I've attached two patches: one for ComboBoxDataStore? and one for dojo.data. I thought it would be good if dojo.data could match values even if they contained newlines.

[haysmark]

I ran the dojo.data patch against the doh tests in dojo and dojox on Firefox 2, IE 7, and Safari 3.1 and they all passed.

(In [14323]) Use dojo.trim(). replace() is insufficient since it doesn't remove spaces or tabs.

The other option is to do trimming on lookup rather than on instantiation. We should do that if current strategy affects page load time significantly.
