how to get value of multiple textboxes using jquery ...textbox doesn't have id

Hi,
You can do this in two way.
First if you have all the textbox in a div then you get all the textbox value using children function like this,

function GetTextBoxValueOne() {
  $("#divAllTextBox").children("input:text").each(function () {
    alert($(this).val());
  });
}

Here we get all the textbox's value by its parents div Id.

Now another way is you can give a class name to those textboxes which value you need and get that control with class name like this,

function GetTextBoxValueTwo() {
  $(".text-box").each(function () {
    alert($(this).val());
  });
}

Here we are getting all the value with text-box class name.
Then you can call any of the function from document ready or button click.

I hope this will help.
Thanks :)
