  • Ticket #15043 – Description

    initial v11  
    11I used the code from site http://jqueryui.com/autocomplete/#combobox and noticed a significant performance issue on my page.  My list has ~3000 options in the combobox.  I noticed that most of the time it was stuck in the in the jquery js file within this set of code:
    2 
    3 `       indexOf = function( list, elem ) {
     2{{{#!js
     3        indexOf = function( list, elem ) {
    44                var i = 0,
    55                        len = list.length;
    … …  
    1111                return -1;
    1212        },`
    13 
     13}}}
    1414Even though my list object was only expected to be ~3000 rows, it was actually significantly higher.  Here is my stacktrace:
