Script Pentru Afisarea Nr. De Cuvinte Ramase


Recommended Posts

Scriptul de mai jos, stabileste si verifica numarul de cuvinte introduse intr-un camp textarea, afiseaza numarul de cuvinte scrise, iar daca acest numar este depasit, se afiseaza o fereastra de atentionare.

Introduceti in sectiunea HEAD a documentul HTML, urmatorul script:

<script type="text/javascript">
// De MarPlo (http://www.marplo.net)

function verifica(text) {

 // Aici schimbati numarul maxim de cuvinte
 var maxwords=5;
 var nrc=text.value.split(" ");    // Imparte sirul in functie de caracterul spatiu
 // Verifca daca a fost depasit nr. maxim de cuvinte
 if (nrc.length>maxwords) {
   alert("Va rog adaugati maxim "+maxwords+" cuvinte!")
   return false
 // Afiseaza nr. de cuvinte adaugate
 else {
   document.getElementById("countdown").innerHTML = 'Cuvinte adaugate <b>'+nrc.length+'</b> din maxim <u>'+maxwords+'</u>';
   return true
</script> [/code] Dupa <body> adaugati urmatoarele linii:
[code]<form action="#" name="f" onsubmit="return verifica(document.f.ctest)">
<strong>Adaugati cuvinte cheie</strong><br>
(<i><span id="countdown">Folositi maxim 5 cuvinte</span></i>)<br>
<textarea rows="5" cols="38" name="ctest" onkeydown="verifica(this.value)" onkeyup="verifica(this)"></textarea><br>
<input type="submit" value="Trimite"> &nbsp; &nbsp;
<input type="reset" value="Sterge" name="sterge">
