我有 3 个使用 JSONP 的嵌套 $.ajax 调用,第一个 $.ajax 调用在函数中工作,但第三个调用未能执行回调,给我这个错误:Uncaught TypeError: Property 'insertFilmData' of object [object Object] is not a function
代码:
function searchFilms(film, settings) {
if (film === '') {
console.log("enter a movie");
} else {
$.ajax({
type: 'GET',
url: 'http://api.themoviedb.org/3/configuration?api_key=XXX',
async: false,
jsonpCallback: 'getSearchResults',
contentType: 'application/json',
dataType: 'jsonp',
success: function(json) {
if (json.images) {
settings.imageData = json.images;
getSearchResults(json, settings);
}
}
});
function getSearchResults(data, settings) {
$.ajax({
type: 'GET',
url: 'http://api.themoviedb.org/3/search/movie?api_key=XXX&query=' + film,
async: false,
jsonpCallback: 'deliverResults',
contentType: 'application/json',
dataType: 'jsonp',
success: function(json) {
if (json.total_results !== 0) {
deliverResults(json, settings);
}
}
});
function deliverResults(data, settings) {
var results = data.results;
var html = "<ul id='film-search-results' data-role='listview' data-inset='true'>";
for (var i = 0; i < results.length; i++) {
var result = results[i];
var filmId = result.id;
$.ajax({
type: 'GET',
url: 'http://api.themoviedb.org/3/movie/' + filmId + '?api_key=XXX&append_to_response=' + settings.extras,
async: false,
jsonpCallback: 'insertFilmData',
contentType: 'application/json',
dataType: 'jsonp',
success: function(json) {
if (json) {
settings.html = html;
insertFilmData(json, settings);
}
}
});
function insertFilmData(data, settings) {
var poster_base_url = settings.imageData.base_url;
var poster_size = settings.imageData.poster_sizes[0];
var poster_filepath = data.poster_path;
var poster_url = poster_base_url + poster_size + "/" + poster_filepath;
var html = settings.html + "<li><img src='" + poster_url + "' alt='Poster' /><a class='ui-link-inherit'><h3 class='ui-li-heading'>" + data.title + "</h3><p class='ui-li-desc'><strong>" + data.tagline + "</strong></p><p class='ui-li-desc'>" + data.overview + "</p></a></li>";
}
}
html = html + "</ul>";
console.log(html);
$('#content-add-title').html(html);
$('#film-search-results').trigger("create");
}
}
}
}
我对使用 JSONP 进行跨域调用非常陌生,所以我不确定看到前两个回调触发时出了什么问题,而只有最后一个没有触发。任何帮助或方向将不胜感激。谢谢
