Google ChromeコンソールのすべてのJavaScript変数のリストを表示

Firebugでは、[DOM]タブにすべてのパブリック変数とオブジェクトのリストが表示されます。Chromeのコンソールで、探索するパブリック変数またはオブジェクトの名前を入力する必要があります。

Chromeのコンソールですべてのパブリック変数とオブジェクトのリストを表示する方法、または少なくともコマンドはありますか？タイピングの手間が省けます。

これはあなたが探している種類の出力ですか？

for(var b in window) { 
  if(window.hasOwnProperty(b)) console.log(b); 
}

この意志のリストで利用可能なすべてwindowのオブジェクト（たとえば、すべての関数と変数、$およびjQueryこのページの、など）。しかし、これはかなりのリストです。それがどれほど役立つかわかりません...

それ以外の場合はwindow、実行してツリーを下っていきます。

window

これDOMWindowにより、展開可能/探索可能なオブジェクトが提供されます。

スクリプトの実行が停止したとき（ブレークポイントなど）、開発者ツールウィンドウの右側のペインにすべてのグローバルを表示できます。

コンソールを開き、次のように入力します。

• keys(window) 変数を確認するには
• dir(window) オブジェクトを見る

windowあなたがコンソールに入力して、すべての変数/属性/機能を表示するために拡張することができるようにオブジェクトは、すべてのパブリック変数が含まれています。

ウィンドウオブジェクトのすべての標準プロパティを除外し、アプリケーション固有のグローバルを表示する場合は、Chromeコンソールに出力します。

(function(){var standardGlobals=["top","window","location","external","chrome","document","inlineCSS","target","width","height","canvas","data","DOMURL","img","svg","ctx","url","w","a","speechSynthesis","webkitNotifications","localStorage","sessionStorage","applicationCache","webkitStorageInfo","indexedDB","webkitIndexedDB","crypto","CSS","performance","console","devicePixelRatio","styleMedia","parent","opener","frames","self","defaultstatus","defaultStatus","status","name","length","closed","pageYOffset","pageXOffset","scrollY","scrollX","screenTop","screenLeft","screenY","screenX","innerWidth","innerHeight","outerWidth","outerHeight","offscreenBuffering","frameElement","clientInformation","navigator","toolbar","statusbar","scrollbars","personalbar","menubar","locationbar","history","screen","postMessage","close","blur","focus","ondeviceorientation","ondevicemotion","onunload","onstorage","onresize","onpopstate","onpageshow","onpagehide","ononline","onoffline","onmessage","onhashchange","onbeforeunload","onwaiting","onvolumechange","ontimeupdate","onsuspend","onsubmit","onstalled","onshow","onselect","onseeking","onseeked","onscroll","onreset","onratechange","onprogress","onplaying","onplay","onpause","onmousewheel","onmouseup","onmouseover","onmouseout","onmousemove","onmouseleave","onmouseenter","onmousedown","onloadstart","onloadedmetadata","onloadeddata","onload","onkeyup","onkeypress","onkeydown","oninvalid","oninput","onfocus","onerror","onended","onemptied","ondurationchange","ondrop","ondragstart","ondragover","ondragleave","ondragenter","ondragend","ondrag","ondblclick","oncuechange","oncontextmenu","onclose","onclick","onchange","oncanplaythrough","oncanplay","oncancel","onblur","onabort","onwheel","onwebkittransitionend","onwebkitanimationstart","onwebkitanimationiteration","onwebkitanimationend","ontransitionend","onsearch","getSelection","print","stop","open","showModalDialog","alert","confirm","prompt","find","scrollBy","scrollTo","scroll","moveBy","moveTo","resizeBy","resizeTo","matchMedia","requestAnimationFrame","cancelAnimationFrame","webkitRequestAnimationFrame","webkitCancelAnimationFrame","webkitCancelRequestAnimationFrame","captureEvents","releaseEvents","atob","btoa","setTimeout","clearTimeout","setInterval","clearInterval","TEMPORARY","PERSISTENT","getComputedStyle","getMatchedCSSRules","webkitConvertPointFromPageToNode","webkitConvertPointFromNodeToPage","webkitRequestFileSystem","webkitResolveLocalFileSystemURL","openDatabase","addEventListener","removeEventListener","dispatchEvent"];
    var appSpecificGlobals={};
    for (var w in window){
        if (standardGlobals.indexOf(w)==-1) appSpecificGlobals[w]=window[w];
    }
    console.log(appSpecificGlobals);})()

スクリプトはブックマークレットとしてうまく機能します。スクリプトをブックマークレットとして使用するには、新しいブックマークを作成し、URLを次のように置き換えます。

javascript:(function(){var standardGlobals=["top","window","location","external","chrome","document","inlineCSS","target","width","height","canvas","data","DOMURL","img","svg","ctx","url","w","a","speechSynthesis","webkitNotifications","localStorage","sessionStorage","applicationCache","webkitStorageInfo","indexedDB","webkitIndexedDB","crypto","CSS","performance","console","devicePixelRatio","styleMedia","parent","opener","frames","self","defaultstatus","defaultStatus","status","name","length","closed","pageYOffset","pageXOffset","scrollY","scrollX","screenTop","screenLeft","screenY","screenX","innerWidth","innerHeight","outerWidth","outerHeight","offscreenBuffering","frameElement","clientInformation","navigator","toolbar","statusbar","scrollbars","personalbar","menubar","locationbar","history","screen","postMessage","close","blur","focus","ondeviceorientation","ondevicemotion","onunload","onstorage","onresize","onpopstate","onpageshow","onpagehide","ononline","onoffline","onmessage","onhashchange","onbeforeunload","onwaiting","onvolumechange","ontimeupdate","onsuspend","onsubmit","onstalled","onshow","onselect","onseeking","onseeked","onscroll","onreset","onratechange","onprogress","onplaying","onplay","onpause","onmousewheel","onmouseup","onmouseover","onmouseout","onmousemove","onmouseleave","onmouseenter","onmousedown","onloadstart","onloadedmetadata","onloadeddata","onload","onkeyup","onkeypress","onkeydown","oninvalid","oninput","onfocus","onerror","onended","onemptied","ondurationchange","ondrop","ondragstart","ondragover","ondragleave","ondragenter","ondragend","ondrag","ondblclick","oncuechange","oncontextmenu","onclose","onclick","onchange","oncanplaythrough","oncanplay","oncancel","onblur","onabort","onwheel","onwebkittransitionend","onwebkitanimationstart","onwebkitanimationiteration","onwebkitanimationend","ontransitionend","onsearch","getSelection","print","stop","open","showModalDialog","alert","confirm","prompt","find","scrollBy","scrollTo","scroll","moveBy","moveTo","resizeBy","resizeTo","matchMedia","requestAnimationFrame","cancelAnimationFrame","webkitRequestAnimationFrame","webkitCancelAnimationFrame","webkitCancelRequestAnimationFrame","captureEvents","releaseEvents","atob","btoa","setTimeout","clearTimeout","setInterval","clearInterval","TEMPORARY","PERSISTENT","getComputedStyle","getMatchedCSSRules","webkitConvertPointFromPageToNode","webkitConvertPointFromNodeToPage","webkitRequestFileSystem","webkitResolveLocalFileSystemURL","openDatabase","addEventListener","removeEventListener","dispatchEvent"]; var $appSpecificGlobals={};for (var w in window){if (standardGlobals.indexOf(w)==-1) $appSpecificGlobals[w]=window[w];} window.$appSpecificGlobals=$appSpecificGlobals;console.log(window.$appSpecificGlobals);})()

デビッドウォルシュはこれのための素晴らしい解決策を持っています。これが私の見解です。彼のソリューションとこのスレッドで発見されたものを組み合わせています。

https://davidwalsh.name/global-variables-javascript

x = {};
var iframe = document.createElement('iframe');
iframe.onload = function() {
    var standardGlobals = Object.keys(iframe.contentWindow);
    for(var b in window) { 
      const prop = window[b];
      if(window.hasOwnProperty(b) && prop && !prop.toString().includes('native code') && !standardGlobals.includes(b)) {
        x[b] = prop;
      }
    }
    console.log(x)
};
iframe.src = 'about:blank';
document.body.appendChild(iframe);

x 現在はグローバルのみです。

JavaScriptコンソールに次のステートメントを入力します。

debugger

これで、通常のデバッグツールを使用してグローバルスコープを検査できます。

公平を期すために、ブラウザーの組み込みを含め、スコープ内のすべてのものを取得するwindowので、これは一種の干し草のような体験になるかもしれません。：/

このChrome向けFirebug lite拡張機能をお試しください。

変数をChromeで表示するには、[ソース]に移動し、[ウォッチ]に移動して追加します。ここに「ウィンドウ」変数を追加すると、変数を展開して探索できます。

Avindraが言及した同じ記事から更新されたメソッド— iframeを挿入し、そのcontentWindowプロパティをグローバルウィンドウプロパティと比較します。

(function() {
  var iframe = document.createElement('iframe');
  iframe.onload = function() {
    var iframeKeys = Object.keys(iframe.contentWindow);
    Object.keys(window).forEach(function(key) {
      if(!(iframeKeys.indexOf(key) > -1)) {
        console.log(key);
      }
    });
  };
  iframe.src = 'about:blank';
  document.body.appendChild(iframe);
})();

タイプ：thisコンソールで、

window object私が思う（？）を得るために、それは基本的にタイピングと同じだと思いますwindowにはコンソールでの。

少なくともFirefoxとChromeでは機能します。

すべての「パブリック変数」は実際には（表示しているウィンドウ/タブの）ウィンドウオブジェクトのプロパティなので、代わりに「ウィンドウ」オブジェクトを検査するだけで済みます。複数のフレームがある場合は、とにかく正しいウィンドウオブジェクト（Firebugなど）を選択する必要があります。

次の簡単なコマンドを試してください：

console.log（ウィンドウ）

変数とその値をリストする

for(var b in window) { if(window.hasOwnProperty(b)) console.log(b+" = "+window[b]); }

特定の変数オブジェクトの値を表示する

console.log(JSON.stringify(content_of_some_variable_object))
