Question

i have a set of text boxes. I gave the id as an array as pageid[]

so id of first text box is pageid[0]

Am trying to do some action on that based on id

for eg:

$("#pageid[0]").val("1234");

I’m not getting any error. Am I doing anything wrong?

Answer 1

Try:

$("#pageid\\[0\\]").val("1234");

Oh and by the way you have invalid HTML because according to the specification:

ID and NAME tokens must begin with a letter ([A-Za-z]) and may be
followed by any number of letters, digits ([0-9]), hyphens (“-“),
underscores (“_”), colons (“:”), and periods (“.”).

So [ and ] should not be used in your ids and names.
