问题 I've tested the following code in both Firefox (32) and Chrome (38) so far var startTime = (new Date()).getTime(); console.log(startTime); var data = []; var tCat = "ABCDEFGHIJKLMNOPQRSTUVWXYZ".split(""); var dataPoints = 2000000; for ( var i = 0; i < dataPoints; i++ ) { var r = Math.random; data.push({ value: Math.pow(1 - Math.cos((r() * Math.PI) / 2), 3), cost: +r().toFixed(2), category: tCat[Math.floor(r() * tCat.length)] }); } var endTime = (new Date()).getTime(); console.log(endTime);

问题 I have the following line in my JavaScript file, which creates an error message on the console: myObject.width = 315; I want to hide this error message on the console. I mean that, this line of code will run, it will give error, but won't display it on the console log. I read about window.onerror , but it did not work. As I understand, this disables all the errors on a page, however I want to disable the errors of only my line. I tried putting it right after, but it didn't work either:

问题 I'm trying to understand how js prototypes and classes work, and I'm using Chrome's console.log to print and have a look at the state of my objects while I add new properties etc. This is the code I'm using: (fiddle) function Person(){} Person.prototype.sayHello = function(){ alert("Hello"); }; Person.prototype.name = "Name"; console.log(Person.prototype) //1st console.log Person.prototype.surname = "Surname"; console.log(Person.prototype); //2nd console.log I expect to have two different

问题 So I have the following function: var multiplyT = function(a, b, acc) { if (b == 0) { console.log("BASE CASE: ", acc); return acc; } else { b--; acc = acc + a; console.log("NOT THE BASE CASE: ", a,b,acc); multiplyT(a, b, acc); } } It gets called with: console.log(multiplyT(5,3,0)); And gives this: NOT THE BASE CASE: 5 2 5 NOT THE BASE CASE: 5 1 10 NOT THE BASE CASE: 5 0 15 BASE CASE: 15 undefined As output. What I am confused about is why acc would give the correct value for the console.log

问题 I have a string of maybe 20 or 30 lines i'd like to output to the console all in one console.log call. This works great in Chrome, but IE11 truncates about half of the string in the console. Any way to prevent this? The string is something like: ----------------------------------------- Wed Jan 7 20:41:16 GMT-0700 2015 530d8aa855df0c2d269a5a5853a47a049c52c9d83a2d71d9 ----------------------------------------- 41:17:181 - Initiating recording... 41:17:233 - Creating NetStream... 41:17:240 -

问题 I want to access the data in the second array from the following code: var data = [ ["Team 1", 3], ["Team 2", 6], ["Team 3", 9]]; I am trying to access the "team" and "team number" using the following functions. _Chart._accessors = { `"team": function(data) { return data[0]; },` `"current": function(data) { return data[0]; }` }; When I check the console log team, and current return arrays of two items which is logical. My question is how do I access the data inside those arrays? 回答1: The same

问题 I'm adding a bit of functionality to an old ("old" as in "olde"; as in Rip-van-Winkle olde) website that uses VBScript. The upshot of my problem is that certain logic seems to always equate to a single result (IsNewBusiness is always apparently assigned a value of FALSE), whereas it should sometimes equate to the opposite, that logic being: IsNewBusiness = TRUE 'default (if record not found) If Not adoRS.EOF Then IsNewBusiness = adoRS.Fields.Item(0).Value <> 0 End If So, since the logic is

问题 From my addon scope I am trying to log messages to the Browser Console with functions like console.log and console.info etc as seen here MDN - Web API Interfaces - Console However Services.jsm gives me nsIConsoleService .

问题 While building a game where there is nested array grid to represent tiles , i was trying to determine "neighboring" tiles type , and ran into a coding mistake. When i tried to debug , i wanted to console.log some objects , but my browser gave me weird output. When the object is written on one line , the values seem to be somewhat right ( except for that mistake of mine ) but when i wanted to display the rest of the object (click and roll-down) , it showed me entirely different values. Is this
