JQuery Terminal term.echo from another function?

Question

I am trying to use: http://terminal.jcubic.pl/

I want to be able to call term.echo from another function to be able to place data inside the terminal, but I can not reference it.

Heres the code below:

jQuery(document).ready(function($) {
    var id = 1;
    $('body').terminal(function(command, term) {
        if (command == 'help') {
            term.echo("available commands are mysql, js, test");
        } else{
          term.echo("entered: " + command);
        }

    }, {
        greetings: "Shell",
        onBlur: function() {
            return false;
        }
    });
});

How can I access term.echo externally, so I can from like a button click call term.echo to add in data?

Simplest way is to use global variable as a reference for a term object. In your example that can look like follows:

// global placeholder for term object
var terminal = null;

jQuery(document).ready(function($) {
    var id = 1;
    $('body').terminal(function(command, term) {

        // setting up global reference
        terminal = term;

        if (command == 'help') {
            term.echo("available commands are mysql, js, test");
        } else{
          term.echo("entered: " + command);
        }

    }, {
        greetings: "Shell",
        onBlur: function() {
            return false;
        }
    });
});

The issue with this code is that it will load terminal after the ready event fired on document and you are never sure when that happens.

After document.ready fired you will be able to use terminal.echo(''); anywhere.

The value returned by the terminal is the same object as in interpter parameter (in both cases is jQuery object with additional terminal methods), so you can do something like this:

jQuery(function($) {
    var terminal = $('body').terminal(function(command, term) {
        if (command == 'help') {
            term.echo("available commands are mysql, js, test");
        } else{
          term.echo("entered: " + command);
        }

    }, {
        greetings: "Shell"
    });

    terminal.echo("Some text");
});

Can i send only characters with echo()? It appends a new line after my text. I dont want that! – feedc0de Apr 09 '15 at 06:04
@0xFEEDC0DE you can't, echo will always add new line at the end. – jcubic Apr 09 '15 at 08:26
I dont want to get new lines added after each echo. Is there another function to do this? – feedc0de Apr 09 '15 at 11:49
