famo.us中响应式应用程序的最佳模式是什么

Question

举例来说,在基于引导程序的应用程序中,我可能会编写标记,使网格对于大屏幕为8列宽,对于小屏幕为2列宽.

屏幕尺寸肯定会对屏幕设计产生影响,我想知道在我开始在famo.us中尝试之前要遵循什么样的模式.看到famo.us是"意见",这里应该只有一个答案:)

我全都是移动优先设计,但我不想要的是桌面应用程序,它只是一个延伸400%的移动应用程序.

谢谢,

安德鲁

基于Github上的Famo.us示例中的示例..

https://github.com/Famous/examples/blob/master/src/examples/views/GridLayout/example.js

你可以很容易地做这样的事情..

var Engine     = require("famous/core/Engine");
var Surface    = require("famous/core/Surface");
var GridLayout = require("famous/views/GridLayout");

var mainContext = Engine.createContext();

var contextSize = mainContext.getSize()

var dimensions;

if (contextSize[0] < 480 || contextSize[1] < 480) {
    dimensions = [2,8];
} else {
    dimensions = [8,2];
};

var grid = new GridLayout({
    dimensions: dimensions
});

var surfaces = [];
grid.sequenceFrom(surfaces);

for(var i = 0; i < 16; i++) {
    surfaces.push(new Surface({
        content: "I am panel " + (i + 1),
        size: [undefined, contextSize[1] / 2.0],
        properties: {
            backgroundColor: "hsl(" + (i * 360 / 16) + ", 100%, 50%)",
            color: "black",
            lineHeight: window.innerHeight / 2 + 'px',
            textAlign: 'center'
        }
    }));
}

mainContext.add(grid);

编辑:

因为最终目标是Javascript作为现代Web应用程序的唯一开发语言.有时您只需要自己管理事物.

对于像Famo.us这样强烈依赖于绝对定位的框架尤其如此.事情就像箱子模型一样不流畅

为了处理所有细微差别,我构建了一个StateHash类来管理状态,并根据当前状态返回相同键的不同值.

var DESKTOP, MOBILE, StateHash, screen_state, sh;

StateHash = (function() {

  function StateHash(states) {
    this.set_state = __bind(this.set_state, this);

    this.get_state = __bind(this.get_state, this);

    this.set = __bind(this.set, this);

    this.get = __bind(this.get, this);

    var i, _i, _ref;
    if (!states) {
      states = 2;
    }
    this.state = 0;
    this.hash = {};
    for (i = _i = 0, _ref = states - 1; 0 <= _ref ? _i <= _ref : _i >= _ref; i = 0 <= _ref ? ++_i : --_i) {
      this.hash[i] = {};
    }
  }

  StateHash.prototype.get = function(key) {
    return this.hash[this.state][key];
  };

  StateHash.prototype.set = function(state, key, val) {
    return this.hash[state][key] = val;
  };

  StateHash.prototype.get_state = function() {
    return this.state;
  };

  StateHash.prototype.set_state = function(state) {
    return this.state = state;
  };

  return StateHash;

})();

// Usage

MOBILE = 0;
DESKTOP = 1;

screen_state = some_check_mobile_function() ? MOBILE : DESKTOP;

sh = new StateHash();
sh.set_state(screen_state);

sh.set(MOBILE, "top-margin", "10px");
sh.set(DESKTOP, "top-margin", "20px");

sh.get("top-margin");

如果我了解其他任何更好的方法,我会告诉你的!

祝好运!
