Editor de texto en javascript

Publicado por Hernán (3 intervenciones) el 15/12/2009 17:47:45
Hola, consegui un codigo de la web para poder realizar un editor de texto en un textbox de php. Lo que quiero hacer es que el usuario pueda darle forma a sus texto y luego enviarlo a la base de datos.
Estuve tocando un poco el código y funciona bien con la base de datos. Sólo que cuando el usuario escribe directamente sin elegir ninguna opcion (o sea negrita, subrayado, etc) me deja dos lineas entre cada renglón o sea 2 </br> del php. No conozco mucho del código java y necesitaría ver si me ayudan a solucionar este pequeño inconveniente. Aquí les paso el codigo:

if (o(idTa).nodeName=="TEXTAREA"){
o(idTa).style.color='#060';
o(idTa).style.zIndex='2';
} else w('<input type="hidden" id="wzhid_'+idTa+'" name="'+idTa+'" />');
h(idTa);
var frm=o(idTa).parentNode;
while (frm.nodeName != 'FORM') frm=frm.parentNode;//if not form, keep trying
addEvt(frm,"submit",syncTextarea);
w('<style type="text/css">button {vertical-align:middle;padding:0;margin:1px 0} button img{vertical-align:middle;margin:-1px} select{vertical-align:middle;margin:1px} .wzCtrl {background:ButtonFace; border:2px outset ButtonShadow; padding:5px;} #sourceTa{color:#060;font-family:mono;} #whizzyWig {border-width:1px}</style>');
var dsels='formatblock';
if (!navigator.userAgent.match('AppleWebKit')){dsels+=' fontname fontsize'} //Font u/s on Chrome/Safari
var dbuts=' bold italic underline | left center right justify | number bullet indent outdent | undo redo | color hilite rule | link image table | clean html spellcheck ';
btns=dbuts.split(' ');
for (var i=0, pos=0; i < btns.length; i++) {
if(btns[i] && btns[i]!='|') {btn[btns[i]]=btn._w*pos++};
}
var tbuts=' tstart add_row_above add_row_below delete_row | add_column_before add_column_after delete_column | table_in_cell';
var t_end=''; //table controls end, if needed
controls=controls ? controls.toLowerCase() : "all";
if (controls == "all") controls=dsels +' newline '+ buts + dbuts + tbuts;
else controls += tbuts;
w('<div style="width:'+taWidth+'" onmouseover="c(\''+idTa+'\')"><div id="CONTROLS'+idTa+'" class="wzCtrl" unselectable="on">');
gizmos=controls.split(' ');
for (var i=0; i < gizmos.length; i++) {
if (gizmos[i]){ //make buttons and selects for toolbar, in order requested
if (gizmos[i] == 'tstart') {
w('<div id="TABLE_CONTROLS'+idTa+'" style="display:none" unselectable="on">');
t_end='</div>';
}
else if (gizmos[i] == '|') w(' <big style="padding-bottom:2em">|</big> ');
else if (gizmos[i] == 'newline') w('<br>');
else if ((dsels+sels).indexOf(gizmos[i]) != -1) makeSelect(gizmos[i])
else if ((dbuts+buts+tbuts).indexOf(gizmos[i]) != -1) makeButton(gizmos[i]);
}
}
