How to get autocompletion data in chrome developer console by javascript? -

-

enter image description here

hello.

i want of auto-completion data above picture javascript.

for example,

console.log(data) // data auto-completion data    ["a[0]", "__definegetter__", "__definesetter__", ...] // result of above command

any ideas autocompletion data?

thank you.

you want properties (even non enumerated) of object present prototype chain (e.g. using __proto__). e.g. : 

a = new array(10);  a[0] = 1; console.log(object.getownpropertynames(a).concat(object.getownpropertynames(a.__proto__)).concat(object.getownpropertynames(a.__proto__.__proto__)));

will print: 

["0", "length", "length", "constructor", "tostring", "tolocalestring", "join", "pop", "push", "concat", "reverse", "shift", "unshift", "slice", "splice", "sort", "filter", "foreach", "some", "every", "map", "indexof", "lastindexof", "reduce", "reduceright", "entries", "keys", "copywithin", "find", "findindex", "fill", "constructor", "tostring", "tolocalestring", "valueof", "hasownproperty", "isprototypeof", "propertyisenumerable", "__definegetter__", "__lookupgetter__", "__definesetter__", "__lookupsetter__", "__proto__"]

suddenly have started receiving above error without changes having been made script. host 1and1 (i know...) the script still works fine on different server, , suspicion there must have been server config change has lead this, although hosts plead ignorance. there's no information on above error @ in google can find - have ideas? server running apache if helps. had similar problem. came out of blue. no php code changed. what changed: php upgraded 5.5.25-1 5.5.26. a security risk in php mail() function has been fixed , newlines in additional_headers allowed no more. because newlines mean: starts email message (and surely don't want inject newlines through headers followed evil message). what have worked fine, e.g. having newlines after headers or passing whole message additional_headers , function no more. solution : sanitize headers. no multiple newlines in additional_headers argument. these count "multiple or malformed newlines":...
