I\'m trying to select this element which has square brackets in the name attribute:
The attribute selector syntax is [name=value] where name is the attribute name and value is the attribute value.
So if you want to select all input elements with the attribute name having the value inputName[]:
$('input[name="inputName[]"]')
And if you want to check for two attributes (here: name and value):
$('input[name="inputName[]"][value=someValue]')
