Feature #8178
openAllow setting attributes for form elements in package XML
0%
Description
I'd like to suggest a couple of enhancements that would make package interfaces easier to work with when enhancing them with JavaScript.
Given a couple of typical form elements in the package XML:
<field> <fielddescr>Description</fielddescr> <fieldname>desc</fieldname> <description>Enter a description for this item.</description> <type>input</type> <size>70</size> </field> <field> <fielddescr>Setting</fielddescr> <fieldname>sett</fieldname> <description>Enable a setting for this item.</description> <type>checkbox</type> </field>
The only way to work with them via JavaScript is by name/id:
$("input#desc").attr("disable", false); $("input#sett").attr("disabled", false);
Not terrible, but it can be very wasteful to create a dozen new jQuery instances to enable some elements. It would be nice to be able to specify a class name:
<field> <fielddescr>Description</fielddescr> <fieldname>desc</fieldname> <description>Enter a description for this item.</description> <type>input</type> <size>70</size> <class>enable_me</class> </field> <field> <fielddescr>Setting</fielddescr> <fieldname>sett</fieldname> <description>Enable a setting for this item.</description> <type>checkbox</type> <class>enable_me</class> </field>
And then we can work with that:
$(".enable_me").attr("disable", false);
Another feature that could be useful is the ability to use data attributes (https://developer.mozilla.org/en-US/docs/Learn/HTML/Howto/Use_data_attributes). XML like this:
<field> <fielddescr>Description</fielddescr> <fieldname>desc</fieldname> <description>Enter a description for this item.</description> <type>input</type> <size>70</size> <class>enable_me</class> <data> <entry name="field1" value="foo"/> <entry name="field2" value="bar"/> </data> </field>
Might produce HTML like this:
<input type="text" name="desc" id="desc" class="enable_me" data-field1="foo" data-field2="bar"/>

Good suggestions. The package manager XML thing is something of a nightmare to work on, but this might not be too bad.
