How to copy the objects from chrome console window?

问题

I have tried to copy the objects as text, but it show just [object object]. Before this I had tried with copy commend it was success but not now.Is that chrome issue?

What I tried? Just Right click on the object and store as global variable from chrome console window, then next just used copy(temp6) command and tried to paste in notepad++.

回答1:

It should ideally copy the object with the copy command that you wrote. I just tried it and worked for me.
Something else that you can try to do is to stringify that object and then copy it.
Ex.

copy(JSON.stringify(temp6))

回答2:

If the object already logged

Right-click on the object in console and click Store as a global
variable the output will be something like temp1

Copy and paste below code in chrome console and hit enter

(function(console){
    console.save = function(data, filename){

    if(!data) {
        console.error('Console.save: No data')
        return;
    }

    if(!filename) filename = 'console.json'

    if(typeof data === "object"){
        data = JSON.stringify(data, undefined, 4)
    }

    var blob = new Blob([data], {type: 'text/json'}),
        e    = document.createEvent('MouseEvents'),
        a    = document.createElement('a')

    a.download = filename
    a.href = window.URL.createObjectURL(blob)
    a.dataset.downloadurl =  ['text/json', a.download, a.href].join(':')
    e.initMouseEvent('click', true, false, window, 0, 0, 0, 0, 0, false, false, false, false, 0, null)
    a.dispatchEvent(e)
 }
})(console)

Then you can use the function for downloading,

console.save(temp1);

-If it shows Uncaught TypeError: Converting circular structure to JSON

then you need decycle JSON object and paste below code in chrome browser console and hit enter

if (typeof JSON.decycle !== "function") {
    JSON.decycle = function decycle(object, replacer) {
        "use strict";

        var objects = new WeakMap();     // object to path mappings

        return (function derez(value, path) {


            var old_path;  
            var nu;  

            if (replacer !== undefined) {
                value = replacer(value);
            }

            if (
                typeof value === "object" && value !== null &&
                !(value instanceof Boolean) &&
                !(value instanceof Date) &&
                !(value instanceof Number) &&
                !(value instanceof RegExp) &&
                !(value instanceof String)
            ) {


                old_path = objects.get(value);
                if (old_path !== undefined) {
                    return {$ref: old_path};
                }

                objects.set(value, path);

                if (Array.isArray(value)) {
                    nu = [];
                    value.forEach(function (element, i) {
                        nu[i] = derez(element, path + "[" + i + "]");
                    });
                } else {

                    nu = {};
                    Object.keys(value).forEach(function (name) {
                        nu[name] = derez(
                            value[name],
                            path + "[" + JSON.stringify(name) + "]"
                        );
                    });
                }
                return nu;
            }
            return value;
        }(object, "$"));
    };
}


if (typeof JSON.retrocycle !== "function") {
    JSON.retrocycle = function retrocycle($) {
        "use strict";

        var px = /^\$(?:\[(?:\d+|"(?:[^\\"\u0000-\u001f]|\\([\\"\/bfnrt]|u[0-9a-zA-Z]{4}))*")\])*$/;

        (function rez(value) {



            if (value && typeof value === "object") {
                if (Array.isArray(value)) {
                    value.forEach(function (element, i) {
                        if (typeof element === "object" && element !== null) {
                            var path = element.$ref;
                            if (typeof path === "string" && px.test(path)) {
                                value[i] = eval(path);
                            } else {
                                rez(element);
                            }
                        }
                    });
                } else {
                    Object.keys(value).forEach(function (name) {
                        var item = value[name];
                        if (typeof item === "object" && item !== null) {
                            var path = item.$ref;
                            if (typeof path === "string" && px.test(path)) {
                                value[name] = eval(path);
                            } else {
                                rez(item);
                            }
                        }
                    });
                }
            }
        }($));
        return $;
    };
}

Then finally execute code for downloading.

console.save(JSON.decycle(temp1));

回答3:

You can use command in console as follows: Let say our object is:

  var object = {x:"xyz"}

Now use below command in console -

 copy(JSON.stringify(object))

object is now available to clipboard.You can now use Ctrl + v to use this object.

回答4:

You need to check thecount object to avoid circular reference, before adoptcopy(JSON.stringify(count)), please see here

回答5:

there can be many ways to do this. One way could be to do JSON.stringify(yourObject) and then copy the output.
