Break out of Javascript validation …

Copy linkTweet thisAlerts:
Jun 03.2009

I have a list of validations on the save event of a form…

but when :

f.myval2.value !== f.myval3.value

is true i want to stop tha javascript and get them to do something else…

But it keeps failing by trying to proceed through the validation.
I have put a Break command in but am being told its invalid…

any help appreciated…

thanks

if (f.myval2.value !== f.myval3.value) {
break;
alert (“You must complete the info form before continuing….”);

return false;
}

@Declan1991Jun 03.2009 — No, breaks are for loops and switch. Use return.

@DelanJun 04.2009 — Er... you can't use return before the alert statement... well you can, but the alert call will never happen. Use "return;" after "alert(...)".

I was under the impression that he wantedif (f.myval2.value !== f.myval3.value) {
alert ("You must complete the info form before continuing....");
return false;
} ORif (f.myval2.value === f.myval3.value) {
return true;
}
alert ("You must complete the info form before continuing....");
return false;
But he thought that break could be used in an if statement. Actually, there is a "horror story" about a break being used incorrectly to break out of an if, breaking out of the outer loop and causing chaos. Moral of the story, never use a break unless you are absolutely sure it is breaking out of the loop you want.

Success!
