Different Javascript on iPhone than Win 10 desktop?

I have this code in a program specifically designed (from a user interface perspective) to run on phone size devices.

if (document.st.pn.value == "" || document.st.padr.value == "" || document.st.cityf.value == "" || document.st.zip.value == "") {
					alert("Minimum of property name, address, city & zip required.");
					return false;
			}

Open in new window

When the specific form fields as indicated are filled in on the form on my iPhone (an iPhone 6), the test displays the alert, thus preventing submission of the form.

When I run the EXACT same program on a Windows 10 desktop, filling in the required fields, it works.

Does Javascript somehow differ on the iPhone from the desktop. Is it a Safari browser issue?

Thanks

I dont see any issue here...

it should work...

do you have any test link?

Is one of the fields a dropdown?

Different browsers have different engines, but they all work pretty much the same

HainKurt

where do you call this function?

maybe you should just start using jQuery

or use

document.st.pn.value

>>>

document.forms["MyForm"].pn.value

or

document.forms[0].pn.value

if it is first or only form on page...

I will try your suggestions. The test link is not practical, a login is required, I would have to set one up for EE, communicate privately, etc.

I think document.forms[0].pn.value is the easiest to try.

The function this code is in a function called chk_vals & is invoked by the onSubmit event. I can show all the code but it's mixed in with php, etc.

I did not try the other stuff. getElementById worked.
