我对前端MVC的理解

也许很多人跟我一样对明明几行代码就可以敲出来的，却偏偏要用前端mvc很不解。

看例子吧。里面有点问题，有空解决。

这是对照组

<!DOCTYPE html>
<html>

	<head>
		<meta charset="UTF-8">
	</head>

	<body>
		<select id="drinkSelect">
			<option value="coffee">coffee</option>
			<option value="milk">milk</option>
			<option value="juice">juice</option>
		</select>
		<p id="theColorOfDrink"></p>

		<script type="text/javascript">
			document.getElementById("drinkSelect").onchange = function() {
				var color;
				var colorOfDrink = {
					"coffee": "brown",
					"milk": "white",
					"juice": "orange"
				};
				color = colorOfDrink[this.value];
				document.getElementById("theColorOfDrink").innerHTML = color;
			}
		</script>
	</body>

</html>

实验组：这组就是分层了，但是代码有点问题。

<!DOCTYPE html>
<html>

	<head>
		<meta charset="UTF-8">
	</head>

	<body>

		<select id="drinkSelect">
			<option value="coffee">coffee</option>
			<option value="milk">milk</option>
			<option value="juice">juice</option>
		</select>
		<p id="theColorOfDrink"></p>

		<script type="text/javascript">
			//showDrinkColor is Controller
			var showDrinkColor = {
				start: function() {
					this.view.start();
				},
				set: function(drinkName) {
					this.model.setDrink(drinkName);
				}
			};
			//Model
			showDrinkColor.model = {
				colorOfDrink: {
					"coffee": "brown",
					"milk": "white",
					"juice": "orange"
				},
				selectedDrink: null,
				setDrink: function(drinkName) {
					this.selectedDrink = this.colorOfDrink[this.selectedDrink] ? drinkName : null;
					this.onchange();
				},
				onchange: function() {
					showDrinkColor.view.update();
				},
				getDrinkColor: function() {
					return this.selectedDrink ? this.colorOfDrink[this.selectedDrink] : "white";
				}
			};
			//View
			showDrinkColor.view = {
				start: function() {
					document.getElementById("drinkSelect").onchange = this.onchange;
				},
				onchange: function() {
					showDrinkColor.set(document.getElementById("drinkSelect").value);
				},
				update: function() {
					document.getElementById("theColorOfDrink").innerHTML = showDrinkColor.model.getDrinkColor();
				}
			};
			showDrinkColor.start();
		</script>
	</body>
