Prevent "Send Email" dialog until required fields are completed

i'm new js, & struggling 1 last piece of code.

i have form several required fields. sending form email attachment , need required fields completed before form can emailed.

currently, have alert box display if of required fields blank, if cancel alert box, "send email" dialog pops right away , can email form if required fields blank. want "send email" box appear after required textboxes completed.

the problem seems if/else line (if req. fields blank, send alert. else open "send email" box). what’s best way write this? ideally, i'd alert list specific fields blank. here's have @ moment - have wrong):

 

if (requiredfields.length > 0) {
app.alert(error);

} else

var subject = this.getfield("jobnumber").value + " --  request form";
this.maildoc({
cto: "me@mycompany.com",

})

 

 

(using acrobat xi - in advance!)

your call of maildoc after if/else statement.

use this:

 

if (requiredfields.length > 0) {
app.alert(error);

} else {

var subject = this.getfield("jobnumber").value + " --  request form";
this.maildoc({
cto: "me@mycompany.com",

})

}
