I in my web page I have a number of hidden fields to identify if something has been printed, these are all start with 1 of 2 strings for the id so I have this:
var checker = true;
//Check Packing Slips
$("input[id^='OnePrintReference_']").each(function (i, e) {
if ($(this).val() === false) {
checker = false;
};
});
$("input[id^='TwoPrintReference_']").each(function (i, e) {
if ($(this).val() === false) {
checker = false;
};
});
//if check == false do nothing, else do something
However the problem is it is always returning true, even when I have used the debugger and alerts to establish that there are false values, i should I check to see if there is something to loop through as sometimes there won't be a TwoPrintReference_,and
whats the best way to do this

A hidden field value type is a string not a Boolean. A string is never strictly equal to false.
The following link explains the === operator.

How are you setting the hidden fields and what is the value?

Hi EnenDaveyBoy,
As pointed out by mgebhard and bruce (sqlwork.com), your check will always return false.
If you want to check whether the value of your input is "".You could write you code as follows.
if ($(this).val() == false) { checker = false; };Or directly
if ($(this).val()) { checker = false; };For more information falsy value, please refer to https://developer.mozilla.org/en-US/docs/Glossary/Falsy
Best regards,
Ackerly Xu
