validation - form still submitted after return false javascript -



validation - form still submitted after return false javascript -

i'm having little problem validation thing in javascript.

<form action="insert.php" id="form" name="form" method="post" onsubmit="return validate()"> <pre> vul hier de/het e-mail adres(sen) in <textarea name="email" rows="5" cols="50"></textarea><br> typ hier de e-mail <textarea name="text" rows="5" cols="50"></textarea><br> <input type="submit" name="submit" value="submit"> </pre> </form>

as can see here, i've got 2 textareas. in upper one, you're supposed come in 1 or multiple email addresses underneath eachother, , in bottom textarea you're supposed compose email itself. then, when click on submit, it'll send email specified email addresses.

now, i've made validation both textareas:

function explodearray(emailid, delimiter) { temparray = new array(1); var count = 0; var tempstring = new string(emailid); while (tempstring.indexof(delimiter) > 0) { temparray[count] = tempstring.substr(0, tempstring.indexof(delimiter)); tempstring = tempstring.substr( tempstring.indexof(delimiter) + 1, tempstring.length - tempstring.indexof(delimiter) + 1 ); count = count + 1 } temparray[count] = tempstring.replace("\r", ""); homecoming temparray; } function validate() { var emailid = document.form.email; var delimiter = "\n"; var emailarray = explodearray(emailid.value, delimiter); var textid = document.form.text; var length = emailarray.length, element = null; (var = 0; < length; i++) { emailvar = emailarray[i]; if (emailvar == null) { alert("email-adres bestaat niet") emailid.focus() homecoming false } if (emailvar == "") { alert("email-adres veld leeg") emailid.focus() homecoming false } if (checkemail(emailvar) == false) { emailvar.value = "" alert("ongeldig e-mail adres"); emailvar.focus() homecoming false } } if ((textid.value == null) || (textid.value == "")) { alert("e-mail textveld leeg") textid.focus() homecoming false } document.getelementbyid("form").submit(); homecoming true } function checkemail(hallo) { if (/^\w+([\.-]?\w+)*@\w+([\.-]?\w+)*(\.\w{2,3})+$/.test(hallo)) { homecoming true } homecoming false }

(i copied lots of irrelevant code well, sorry that, copied whole thing in case...)

now does work is:

-it won't submit when both textareas empty;

-it won't submit when email addresses valid but bottom textarea empty;

what doesn't work is:

-the form still submits when email addresses invalid, when bottom textarea still empty.

i've been trying figure out hours perchance wrong here, googled , checked stackoverflow, not find anything. tell me i'm doing wrong here?

thanks in advance.

you using emailvar.focus(); won't execute.

here, fixed: live demo

if (checkemail(emailvar) == false) { alert("ongeldig e-mail adres"); emailid.focus(); homecoming false; }

Accessing MATLAB's unicode strings from C -

Accessing MATLAB's unicode strings from C - how can access underlying unicode info of matlab strings through matlab engine or mex c interfaces? here's example. let's set unicode characters in utf-8 encoded file test.txt, read as fid=fopen('test.txt','r','l','utf-8'); s=fscanf(fid, '%s') in matlab. now if first feature('defaultcharacterset', 'utf-8') , c engevalstring(ep, "s") , output text file utf-8. proves matlab stores unicode internally. if mxarraytostring(enggetvariable(ep, "s")) , unicode2native(s, 'latin-1') give me in matlab: non-latin-1 characters replaced character code 26. need getting access underlying unicode info c string in unicode format (utf-8, utf-16, etc.), , preserving non-latin-1 characters. is possible? my platform os x, matlab r2012b. addendum: documentation explicitly states "[mxarraytostring()] supports multibyte encoded characters...
