// DED.util.substitute()函数的使用例子

var substitutionObject = {

name: "world",

place: "Google"

};

var text = 'Hello {name}, welcome to {place}';

var replacedText = DED.util.substitute(text, substitutionObject);

console.log(replacedText);

// produces "Hello world, welcome to Google"

// 原来fooMail的API中getMail的使用方式

fooMail.getMail(function(text) {

$('message-pane').innerHTML = text;

});

// 为dedMail添加适配器，使其调用方式和fooMail的一样

var dedMailtoFooMailAdapter = {};

dedMailtoFooMailAdapter.getMail = function(id, callback) {

dedMail.getMail(id, function(resp) {

var resp = eval('('+resp+')');

var details = '<p><strong>From:</strong> {from}<br>';

details += '<strong>Sent:</strong> {date}</p>';

details += '<p><strong>Message:</strong><br>';

details += '{message}</p>';

callback(DED.util.substitute(details, resp));

});

};

// Other methods needed to adapt dedMail to the fooMail interface.

//todo

// Assign the adapter to the fooMail variable.

// 把适配器赋给fooMail变量，这样就不用修改客户端的其他代码了

fooMail = dedMailtoFooMailAdapter;
