[js] valideren 2 datumwaarden

[Verwijderd]

ik heb 2 datumvelden die gecontroleerd worden als ze gepost worden... Maar hij controleert alleen het eerste datumveld, hoe kan ik ervoor zorgen dat hij ze allebei controleert? Hier een stukkie code...

ik heb b.t.w geen Javascript-errors...

PHP:

echo "<script language=\"Javascript\">\n";
            echo "<!--\n";
        echo "function checkForm() {\n";
                
        echo "// Create a var with the original entered date\n";
        
            echo "mydate = this.document.myform.elements['soprichtdatum'].value;\n";
            echo "mydate2 = this.document.myform.elements['svoorwaardedatum'].value;\n";
                
            echo "// Split the original var in year, month and day\n";
            
            echo "parsedate = mydate;\n";
            echo "parsedate2 = mydate2;\n";
            
            echo "firstpos = parsedate.lastIndexOf( \"-\" );\n";
            echo "firstpos2 = parsedate2.lastIndexOf( \"-\" );\n";
            
            echo "lastpos = parsedate.length;\n";
            echo "lastpos2 = parsedate2.length;\n";
            
            echo "myyear = parsedate.substr( firstpos + 1, lastpos );\n";
            echo "myyear2 = parsedate2.substr( firstpos2 + 1, lastpos2 );\n";
