JavaScript::Code - A JavaScript Code Framework

SYNOPSIS

    #!/usr/bin/perl

    use strict;
    use warnings;
    use JavaScript::Code;
    use JavaScript::Code::Variable;

    # create the code object
    my $code = JavaScript::Code->new();

    # create a code block
    my $block = JavaScript::Code::Block->new();

    # create some variables
    my $var1 = JavaScript::Code::Variable->new()->name('a');
    my $var2 = JavaScript::Code::Variable->new()->name('b')->value(42);
    my $var3 = JavaScript::Code::Variable->new()->name('c')->value(23);
    my $var4 = JavaScript::Code::Variable->new()->name('x')->declared( 1 ); # could have been declared in a other script
    my $var5 = JavaScript::Code::Variable->new()->name('y')->value( ['test', 'uhu', $var4] );

    # add some of them to the code block
    $block->add( [ $var2, $var3] );

    # create some numbers
    my $x1 = JavaScript::Code::Number->new()->value( 10 );
    my $x2 = JavaScript::Code::Number->new()->value( 20 );

    # build expressions
    my $c1 = $var2 - ($x1 + $x2 + $x1->value(30)) * $x2->value(40);
    my $c2 = $c1 * $var3;

    # assign a expression to a variable and add it to your code block
    $block->add( JavaScript::Code::Variable->new()->name('d')->value( $c2 ) );

    # add more stuff to your code block
    $block->add( JavaScript::Code::Block->new()->add( $var1->value("Bar!") ) );
    $block->add( $var1->clone->value("Foo!") ); # clone 'a' and give it a new value

    # add your block and other stuff to the code object
    $code->add( [ $var4->value( 4711 ), $var1->value( "Perl!" ) ] );
    $code->add( $block );
    $code->add( $var2->value(21) ); # 'b' with value 21 (note the different scope)
    $code->add( $var5 );
    $code->add_variable( name => 'c', value => 'Larry' );

    # output to be embedded in your html code
    print $code->output_for_html;
