Hello,

I want to see if there's any "real" content in the textarea before submitting, is there any way to do it ??

I tried this, but the textarea is returning some HTML code... =*(

if(document.form.textarea.replace(/^\s*|\s*$/g,"") == "")
{
alert("Type a message!");
return false;
}

Gecko based browsers place in a <br> for some reason when empty.

I use the following on this forum that may need to be adapted:-

//For Gecko Madis API (RTE)
if (document.frmAddMessage.message.value.indexOf('<br>') > -1 && document.frmAddMessage.message.value.length == 8) document.frmAddMessage.message.value = '';

document.frmAddMessage.message.value.length == 8

document.frmAddMessage.message.value.indexOf('<br>') > -1

GREAT ideia!! =)
