代码如下:
function test() {
return new Promise(function(resolve, reject) {
var ran = Math.random()*10;
if(ran<=5) {
resolve(ran);
}else {
reject(ran);
}
console.log('随机数字 '+ ran);
});
}
Promise.all([test(), test()])
.then(function(data) {
console.log('<=5', data);
}, function(data) {
console.log('>5', data);
});
