私の質問は、JSONの結果からタイトルを取得する方法です。問題の一部は、JSONでは、仕事は配列であり、タイトルは配列項目のbest_bookのメンバーであると私は信じています。 「予期しないトークン」

$.each(json.search.results.work, function(){ 
    console.log(this.best_book.title); 
}); 

が、そうすることで、私はエラーを取得：だから、私のような何かを実装しようとしていますコードの最初の行です。

アイデアはありますか？ありがとうございました。

編集：（あなたの変数にdataを変更する必要があります）ので、同様

function GetBooks(request) { 
    //Replace spaces with a '+' 
    var url = request.term.replace(/\s/g,"+"); 
    return $.ajax({ 
     'url': "php/bookscript.php?search=" + url, 
     'dataType': 'json' 
    }).then(function(data){ 
     return $.map(data.results || [], function(v,i){ 
      return { 
       label: 'test', 
       value: 'test' 
      } 
     }); 
    }) 
} 

Answer 1

：ここに私のAJAX呼び出しの

$.each(data.search.results.work, function(index, value){ 
    console.log(value.best_book.title); 
});

更新：

Iドンラベルは何で、価値はあるのか本当に分かりませんが、 LDヘルプあなた：

$.map(data.search.results.work || [], function(v, i) { 
    return { 
     value : v.best_book.title 
    } 
})
