Answer 1

You need to do two things:

1. Grab the content from the TextArea
2. Loop through the lines and trim each one (removing any empty lines)

CODE:

var content = myTextArea.value;

//Split into lines
var lines = content.split( /\r?\n/ );

//Your new content
var newContent = "";

//Loop through all lines
for ( var i = 0; i < lines.length; i++ )
{
    //Trim it first
    var line = lines[ i ].trim();

    //Empty line, remove it
    if ( line === "" ) continue;

    //Add to new content
    newContent += line + "\n";
}

//Save to text area
myTextArea.value = newContent;
