要查看chrome中的任何变量，请转到“来源”，然后“观看”并添加它。如果你在这里添加“window”变量，那么你可以展开它并进行探索。

我停止使用这个来调试:

for (aProperty in window) {
    try{
        console.log(aProperty +':'+JSON.stringify(window[aProperty]));
    }catch{}
}

try用于避免TypeError:将循环结构转换为JSON 然后另存为…控制台输出到文件中并进行进一步操作。

窗口对象包含所有公共变量，因此您可以在控制台中键入它，然后展开以查看所有变量/属性/函数。

如果你想排除窗口对象的所有标准属性，并查看特定于应用程序的全局变量，这将把它们打印到Chrome控制台:

{

    const standardGlobals = new Set(["window", "self", "document", "name", "location", "customElements", "history", "locationbar", "menubar", "personalbar", "scrollbars", "statusbar", "toolbar", "status", "closed", "frames", "length", "top", "opener", "parent", "frameElement", "navigator", "origin", "external", "screen", "innerWidth", "innerHeight", "scrollX", "pageXOffset", "scrollY", "pageYOffset", "visualViewport", "screenX", "screenY", "outerWidth", "outerHeight", "devicePixelRatio", "clientInformation", "screenLeft", "screenTop", "defaultStatus", "defaultstatus", "styleMedia", "onsearch", "isSecureContext", "performance", "onappinstalled", "onbeforeinstallprompt", "crypto", "indexedDB", "webkitStorageInfo", "sessionStorage", "localStorage", "onabort", "onblur", "oncancel", "oncanplay", "oncanplaythrough", "onchange", "onclick", "onclose", "oncontextmenu", "oncuechange", "ondblclick", "ondrag", "ondragend", "ondragenter", "ondragleave", "ondragover", "ondragstart", "ondrop", "ondurationchange", "onemptied", "onended", "onerror", "onfocus", "onformdata", "oninput", "oninvalid", "onkeydown", "onkeypress", "onkeyup", "onload", "onloadeddata", "onloadedmetadata", "onloadstart", "onmousedown", "onmouseenter", "onmouseleave", "onmousemove", "onmouseout", "onmouseover", "onmouseup", "onmousewheel", "onpause", "onplay", "onplaying", "onprogress", "onratechange", "onreset", "onresize", "onscroll", "onseeked", "onseeking", "onselect", "onstalled", "onsubmit", "onsuspend", "ontimeupdate", "ontoggle", "onvolumechange", "onwaiting", "onwebkitanimationend", "onwebkitanimationiteration", "onwebkitanimationstart", "onwebkittransitionend", "onwheel", "onauxclick", "ongotpointercapture", "onlostpointercapture", "onpointerdown", "onpointermove", "onpointerup", "onpointercancel", "onpointerover", "onpointerout", "onpointerenter", "onpointerleave", "onselectstart", "onselectionchange", "onanimationend", "onanimationiteration", "onanimationstart", "ontransitionrun", "ontransitionstart", "ontransitionend", "ontransitioncancel", "onafterprint", "onbeforeprint", "onbeforeunload", "onhashchange", "onlanguagechange", "onmessage", "onmessageerror", "onoffline", "ononline", "onpagehide", "onpageshow", "onpopstate", "onrejectionhandled", "onstorage", "onunhandledrejection", "onunload", "alert", "atob", "blur", "btoa", "cancelAnimationFrame", "cancelIdleCallback", "captureEvents", "clearInterval", "clearTimeout", "close", "confirm", "createImageBitmap", "fetch", "find", "focus", "getComputedStyle", "getSelection", "matchMedia", "moveBy", "moveTo", "open", "postMessage", "print", "prompt", "queueMicrotask", "releaseEvents", "requestAnimationFrame", "requestIdleCallback", "resizeBy", "resizeTo", "scroll", "scrollBy", "scrollTo", "setInterval", "setTimeout", "stop", "webkitCancelAnimationFrame", "webkitRequestAnimationFrame", "chrome", "caches", "ondevicemotion", "ondeviceorientation", "ondeviceorientationabsolute", "originAgentCluster", "cookieStore", "showDirectoryPicker", "showOpenFilePicker", "showSaveFilePicker", "speechSynthesis", "onpointerrawupdate", "trustedTypes", "crossOriginIsolated", "openDatabase", "webkitRequestFileSystem", "webkitResolveLocalFileSystemURL"]);

    for (const key of Object.keys(window)) {
        if (!standardGlobals.has(key)) {
            console.log(key)
        }
    }
}

该脚本作为书签运行良好。要使用脚本作为书签，请创建一个新书签，并将URL替换为以下内容:

javascript:(() => {
    const standardGlobals = new Set(["window", "self", "document", "name", "location", "customElements", "history", "locationbar", "menubar", "personalbar", "scrollbars", "statusbar", "toolbar", "status", "closed", "frames", "length", "top", "opener", "parent", "frameElement", "navigator", "origin", "external", "screen", "innerWidth", "innerHeight", "scrollX", "pageXOffset", "scrollY", "pageYOffset", "visualViewport", "screenX", "screenY", "outerWidth", "outerHeight", "devicePixelRatio", "clientInformation", "screenLeft", "screenTop", "defaultStatus", "defaultstatus", "styleMedia", "onsearch", "isSecureContext", "performance", "onappinstalled", "onbeforeinstallprompt", "crypto", "indexedDB", "webkitStorageInfo", "sessionStorage", "localStorage", "onabort", "onblur", "oncancel", "oncanplay", "oncanplaythrough", "onchange", "onclick", "onclose", "oncontextmenu", "oncuechange", "ondblclick", "ondrag", "ondragend", "ondragenter", "ondragleave", "ondragover", "ondragstart", "ondrop", "ondurationchange", "onemptied", "onended", "onerror", "onfocus", "onformdata", "oninput", "oninvalid", "onkeydown", "onkeypress", "onkeyup", "onload", "onloadeddata", "onloadedmetadata", "onloadstart", "onmousedown", "onmouseenter", "onmouseleave", "onmousemove", "onmouseout", "onmouseover", "onmouseup", "onmousewheel", "onpause", "onplay", "onplaying", "onprogress", "onratechange", "onreset", "onresize", "onscroll", "onseeked", "onseeking", "onselect", "onstalled", "onsubmit", "onsuspend", "ontimeupdate", "ontoggle", "onvolumechange", "onwaiting", "onwebkitanimationend", "onwebkitanimationiteration", "onwebkitanimationstart", "onwebkittransitionend", "onwheel", "onauxclick", "ongotpointercapture", "onlostpointercapture", "onpointerdown", "onpointermove", "onpointerup", "onpointercancel", "onpointerover", "onpointerout", "onpointerenter", "onpointerleave", "onselectstart", "onselectionchange", "onanimationend", "onanimationiteration", "onanimationstart", "ontransitionrun", "ontransitionstart", "ontransitionend", "ontransitioncancel", "onafterprint", "onbeforeprint", "onbeforeunload", "onhashchange", "onlanguagechange", "onmessage", "onmessageerror", "onoffline", "ononline", "onpagehide", "onpageshow", "onpopstate", "onrejectionhandled", "onstorage", "onunhandledrejection", "onunload", "alert", "atob", "blur", "btoa", "cancelAnimationFrame", "cancelIdleCallback", "captureEvents", "clearInterval", "clearTimeout", "close", "confirm", "createImageBitmap", "fetch", "find", "focus", "getComputedStyle", "getSelection", "matchMedia", "moveBy", "moveTo", "open", "postMessage", "print", "prompt", "queueMicrotask", "releaseEvents", "requestAnimationFrame", "requestIdleCallback", "resizeBy", "resizeTo", "scroll", "scrollBy", "scrollTo", "setInterval", "setTimeout", "stop", "webkitCancelAnimationFrame", "webkitRequestAnimationFrame", "chrome", "caches", "ondevicemotion", "ondeviceorientation", "ondeviceorientationabsolute", "originAgentCluster", "cookieStore", "showDirectoryPicker", "showOpenFilePicker", "showSaveFilePicker", "speechSynthesis", "onpointerrawupdate", "trustedTypes", "crossOriginIsolated", "openDatabase", "webkitRequestFileSystem", "webkitResolveLocalFileSystemURL"]);
