ajax は、「Asynchronous Javascript And XML」(Asynchronous JavaScript and XML) の略で、インタラクティブな Web アプリケーションを作成するための Web 開発テクノロジを指します。
ajax = 非同期 JavaScript および XML (標準汎用マークアップ言語のサブセット)。
ajax は、高速で動的な Web ページを作成するために使用されるテクノロジーです。
バックグラウンドでサーバーと少量のデータを交換することで、ajaxはWebページを非同期に更新できます。これは、ページ全体を再読み込みしなくても、Web ページの一部を更新できることを意味します。
従来の Web ページ (ajax を使用しない) では、コンテンツを更新する必要がある場合、Web ページ全体をリロードする必要があります。非同期リクエスト (XMLHttpRequest オブジェクト)、部分更新 (本質的には js dom)
ajax は、例えば、blog を書く ときに、ユーザー名が繰り返されるかどうかを自動的に判断するためにも使用されます。書いている途中で、突然コンピュータが再起動しました。これで、書いた内容の半分を復元できます。
Get は、URL に含まれるワード数に制限があり、サーバーのコンテンツを変更するために使用されます。 Get は安全なリクエストであり、情報が変更されていないことを確認する必要があります。1、
ajaxは通常、現在のページに使用され、ページジャンプは実装されていません
2、ajaxside: サーバー側のステータスを非同期に監視するにはどうすればよいですか? onreadystatechange を通じて readystate 属性をリッスンします
request.onreadystatechange = function() {<span>if (request.readyState===4) {</span>
open()
がまだ呼び出されていません)。 open()
)。send()
1: リクエストは確立されましたが、まだ送信されていません (send()
がまだ呼び出されていません)。 したがって、一般的には、4に等しいと判断して、対応する演算が実行されます。
ただし、これはリクエストのステータスとは異なることに注意してください
たとえば、readystate=4 but status=404は、レスポンスは完了したが、レスポンスの内容はファイルが見つからないことを意味します
したがって、一般的な==200 の場合に内容を返し、残りは発音エラーを表示するだけです。
投稿リクエストでは、URL をエンコードおよびデコードするように URL を設定する必要があることに注意してください。そうしないと、結果が正しく得られません
request.setRequestHeader("Content-type","application/x-www- form-urlencoded");
しかし、URL デコードには問題があります。URL デコード時にプラス記号は自動的にスペースにデコードされ、& は変数コネクタにデコードされるため、これらの文字が表示される場合は、トランスコードされました
(キャンバスに画像をアップロードするときに URL を使用するとこの問題が発生しました)
Pic = Pic.replace(/+/g, "%2B");
Pic = Pic.replace(/&/g, " %26");
3. サーバーは、echo を通じて ajax に渡されたインターフェイスを返します。
(ヒント: zendstudio の組み込みブラウザーは常に ajax ページの最後のページを表示するため、代わりに外部ブラウザーで実行してください
基本設定 - 一般 - Web ブラウザーの設定。)
単純な行では Jason は必要ありません。Jason は別のキー値を持つデータをより簡単に返すことができます。
