无法将 json 映射到可观察数组。我使用教程中的代码 ( http://learn.knockoutjs.com/ )。
function Movie(data) {
this.name = ko.observable(data.name);
this.description = ko.observable(data.description);
this.duration = ko.observable(data.duration);
this.id = ko.observable(data.id);
this.imdb_id = ko.observable(data.imdb_id);
this.original_name = ko.observable(data.original_name);
this.poster = ko.observable(data.poster);
this.type = ko.observable(data.type);
this.year = ko.observable(data.year);
}
function MovieListViewModel() {
// Data
var self = this;
self.moviesArray = ko.observableArray([]);
self.searchQuery = ko.observable();
self.searchMovies = function () {
$.getJSON("/api/v1/movies/search/", {"query": self.searchQuery }, function(allData) {
var mappedMovies = $.map(allData.movies, function(item) { return new Movie(item) });
console.log(mappedMovies); // in this line output: [Movie, Movie, Movie, Movie, Movie, Movie]
self.moviesArray(mappedMovies);
console.log(self.moviesArray); // in this line output: []
});
};
}
ko.applyBindings(new MovieListViewModel());
我不明白出了什么问题。
附注抱歉我的英语不好
最佳答案
这个
{"query": self.searchQuery }
应该是
{"query": self.searchQuery() }
这个
console.log(self.moviesArray)
应该是
console.log(self.moviesArray())
关于javascript - knockout.js 未从 json 映射可观察数组，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/18118784/
