document.selection no funciona en firefox

[tuweb]

AQUI ESTA LA SOLUCION:


function copyit(theField) {

// si es firefox o crone
if (window.getSelection)
{
var txt = window.getSelection();
ranges = [];
for(var i = 0; i < txt.rangeCount; i++) {
ranges[i] = txt.getRangeAt(i);
//sel.getRangeAt(i).deleteContents();
var acu = ranges[i];
}
theField.value = acu;
}
// si es safari (no le he probado)
else if (document.getSelection)
{
txt = document.getSelection();
foundIn = 'document.getSelection()';
}
// si es internet exploter
else if (document.selection)
{
var txt = document.selection.createRange();

theField.focus();
theField.value = txt.text;
}


}
