这应该是1.3X系列最后一个版本了,大家可以在仓库中看到,多出了一个叫avalon.observe的东西,它是基于Object.observe,dataset, Promise等新API实现。其中,它也使用全新的静态收集依赖的机制,这个机制也完成得差不多,因此avalon与avalon.mobile下一版将会应用这最新成果,进行大改。
着重说一下最后一个新特性。原来定义一个VM大概如下:
var model = avalon.define("test", function(vm) {
vm.firstName = "司徒"
vm.lastName = "正美"
vm.fullName = {//一个包含set或get的对象会被当成PropertyDescriptor,
set: function(val) {//里面必须用this指向scope,不能使用scope
var array = (val || "").split(" ");
this.firstName = array[0] || "";
this.lastName = array[1] || "";
},
get: function() {
return this.firstName + " " + this.lastName;
}
}
vm.click = function() {
alert(vm.firstName)
}
vm.$watch("firstName", function() {
alert(vm.firstName)
})
vm.arr = ["aaa", ‘bbb‘, "ccc", "ddd"]
vm.selected = ["bbb", "ccc"]
vm.checkAllbool = vm.arr.length === vm.selected.length
vm.checkAll = function() {
if (this.checked) {
vm.selected = vm.arr
} else {
vm.selected.clear()
}
}
})
model.selected.$watch("length", function(n) {
model.checkAllbool = n === model.arr.size()
})
现在还可以这样定义:
var model = avalon.define({
$id: "test",
firstName: "司徒",
lastName: "正美",
fullName: {//一个包含set或get的对象会被当成PropertyDescriptor,
set: function(val) {//里面必须用this指向scope,不能使用scope
var array = (val || "").split(" ");
this.firstName = array[0] || "";
this.lastName = array[1] || "";
},
get: function() {
return this.firstName + " " + this.lastName;
},
},
click: function() {
alert(model.firstName)
},
arr: ["aaa", ‘bbb‘, "ccc", "ddd"],
selected: ["bbb", "ccc"],
checkAllbool: true,
checkAll: function() {
if (this.checked) {
model.selected = model.arr
} else {
model.selected.clear()
}
}
})
model.checkAllbool = model.arr.length === model.selected.length
model.$watch("firstName", function() {
alert(model.firstName)
})
model.selected.$watch("length", function(n) {
model.checkAllbool = n === model.arr.size()
})
