Yakagadziriswa: Wona kiyi yekutiza

Dambudziko guru rine chekuita nekuona kiyi yekutiza nderekuti inogona kudzvanywa nyore netsaona. Kana mumwe munhu akadzvanya kiyi yekutiza netsaona, zvinogona kukonzera dambudziko mukombuta.

var escapeKeyCode = 27;

document.onkeydown = function(evt) {
    evt = evt || window.event;
    if (evt.keyCode == escapeKeyCode) {
        alert('Escape key was pressed.');
    }
};

Iyi kodhi inotsanangura basa rinozoitwa chero kiyi inodzvanywa. Kana kiyi yadzvanywa iine kiyi kodhi ye27, yambiro ichabuda ichiti 'Escape key yakadzvanywa.'

Zvinhu uye makirasi

MuJavaScript, zvinhu inzira yekuunganidza data rakabatana pamwechete. Makirasi inzira yekuunganidza kodhi ine hukama pamwechete.

Chinhu chiitiko chekirasi. Kirasi ndiyo template yekugadzira zvinhu. Iwe unogadzira chinhu nekushandisa iyo nyowani kiyi uye kutsanangura zita rekirasi. Semuenzaniso, unogona kugadzira chinhu chinonzi "Munhu" uchishandisa kodhi inotevera:

var munhu = Munhu mutsva();

Iwe unogona zvakare kugadzira chinhu nekushandisa muvaki basa rinotsanangurwa mukirasi. Semuenzaniso, unogona kugadzira chinhu chinonzi "Mudzidzi" uchishandisa kodhi inotevera:

var mudzidzi = Mudzidzi mutsva ();

Python Object Oriented

Python mutauro wakatarisana nechinhu unobvumira vanogadzira kugadzira yakaomesesa software application zviri nyore. Python inozivikanwa nekuverengeka kwayo uye kunzwisisika, zvichiita kuti ive sarudzo yakanaka kune vanogadzira vanoda kunyora kodhi iri nyore kunzwisisa. Python zvakare ine nharaunda yakakura yevagadziri vanowanikwa kuti vakubatsire nemapurojekiti ako, saka iwe unogona kuve nechokwadi chekuti kodhi yako ichanyatso tsigirwa.
