Not sure if I understand. Is this a request to change something? I'm not
too familiar with this portion of the API, and not sure how this might
affect other code, but see my proposed changes below (expanded for ease of
readability).
The line 99:
if(typeof(index)=='number') return
{text:o[index].text,value:o[index].value};
Is proposed to be changed to something like this?
96 | p.getItem = function( index )
97 | {
98 | if ( this.getElm() )
99 | {
100 | var o = this.elm.options;
101 |
102 | if ( typeof( index ) == 'number' && ( index >= 0 || index <
o.length)
103 | {
104 | return { text:o[index].text, value:o[index].value };
105 | }
106 | else if ( typeof( index ) == 'undefined' )
107 | {
108 | return( null );
109 | }
110 | else
111 | {
112 | for( var i = 0; i < o.length; i++ )
113 | {
114 | if ( index == o[i].value )
115 | {
116 | return { text:o[i].text, value:o[i].value };
117 | }
118 | }
119 | }
120 | }
121 | };
