select by name and array value with jquery

Question

I thought that i could do this:

i[1] = 23; // this is built from a regex

$('select [name="sys_map\\['+i[1]+'\\]"]').css('border-color', '#FF5C5C');

or maybe

$('select [name=sys_map\\['+i[1]+'\\]]').css('border-color', '#FF5C5C');

to select

<select name="sys_map[23]">

quoting the name shows error:

[15:36:27.647] Error: Syntax error, unrecognized expression: select [name="sys_map[1]"

You have a space between 'select' and the name attribute selector, so you're looking for elements that match the attribute selector which are descendants of the select.

Change

$('select [name="sys_map\\['+i[1]+'\\]"]')

To

$('select[name="sys_map['+i[1]+']"]')

Here's a fiddle:

Note I had to change your array definition:

var i = [];
i[1] = 23;
