Aptana Javascript如何在aptana中运行单个javascript程序

Question

all I would like to do is run this simple program in Aptana to see if it works, but it doesnt even show up. I used the Javascript Template from Aptana's selection. here is the program.

<script type = "text/javascript" >
function verse (verseNum) {
    var lines = "";
    if (verseNum ==1 ) {
        lines = "One thing I dont know why...";
    } else if (verseNum == 1 {
        lines = "All I know time is a valuable thing...";
    } else {
        lines = "NoLyrics";
    }
    return (lines);
}
alert (verse(1));
alert (verse(2));
</script>

When I run the program, it shows a blank webpage. I am sure it is a very simple mistake, probably completely wrong format. Any help is appreciated.

You are missing a parenthesis, added here:

} else if (verseNum == 1) {

You need to use your browser's console to discover such errors, although I'm surprised that Aptana doesn't indicate it as well.
