我想分配到與功能也對原型創建我的原型的DOM元素分配元素。從DOM來構造原型
我在下面的評論中描述的所有。
摘要:我的原型功能應該產生的DOM元素,把它們放進體內,並立即指派參考他們的原型的財產如。 Game.prototype.boxes = //新創建的DOM元素。
function Game() {
this.class = 'box';
// this.boxes = this.createBoxes(); // It almost works, but isn't on prototype and is duplicated, when I create instance of Monstar class.
}
// Game.prototype.boxes = this.createBoxes(); // I know, in this context 'this' isn't my constructor, but this is method I want to achieve
// Game.prototype.boxes = $('.' + this.class); // As above - 'this' isn't my constructor
Game.prototype.boxes = Game.prototype.createBoxes(); // Alternative test from the lines above. It have to be on my prototype.
Game.prototype.createBoxes = function() {
var docFragment = document.createDocumentFragment();
for(var i = 0; i < 20; i++) {
var elem = $('<div>', {
class: this.class
});
elem.appendTo(docFragment);
}
$(docFragment).appendTo($('body'));
return $('.' + this.class);
};
function Monster() {
Game.call(this);
console.log(this.boxes); // Finally this should returns array with my DOM elements created using prototype createBoxes function.
}
Monster.prototype = Object.create(Game.prototype);
Monster.prototype.constructor = Monster;
var game = new Game(),
monster = new Monster();
console.log(game.boxes); // Finally this should returns array with my DOM elements created using prototype createBoxes function.
感謝所有幫助:)
當然你要的對象分配給你的*實例*的屬性,而不是全局/靜態的原型?你爲什麼要共享DOM元素?通常這正是我們想要避免的。 – Bergi
