Check all values in hash with javascript

Question

I have hash that looks like this:

{ .user_import_163="100%", .user_import_164="99%"}

How in Javascript I can check that all values are equal to 100%?

How did your hash get into javascript? This doesn't look like javascript (where they are called `object`s), or ruby, (where they are called hashes). — Armand, Jun 16 '15 at 11:18
I suppose you're asking how to determine whether two given *objects* are equal, aren't you? — Álvaro González, Jun 16 '15 at 11:18
Yes this is a javascript object. Sorry, my bad. So how can I check if all values in this object are equal to 100% ? — Mateusz Urbański, Jun 16 '15 at 11:20
No, it isn't. In JavaScript objects literals look like `{ attr1: "value1", attr2: "value2" }`. — cezar, Jun 16 '15 at 11:22

@cezar - Most likely, it isn't actual code but a console.log() dump or the source JSON. — Álvaro González, Jun 16 '15 at 11:23

Another sample:

var data = { a: '100%', b: '99%' }

var check = function(obj) {
  var correct = true;

  for (key in obj) {
    if (obj[key] != '100%') correct = false;
  }

  return correct;
}

check(data); // return false
check({ a: '100%', b: '100%' }); // return true

How in Javascript I can check that all values are equal to 100%?

Assuming a valid JavaScript object:

var obj = {
    user_import_163: "100%",
    user_import_164: "99%"
};

or

var obj = {
    ".user_import_163": "100%",
    ".user_import_164": "99%"
};

You can do this:

if (Object.keys(obj).some(function(k) { return obj[k] !== "100%"; })) {
    // At least one isn't equal to "100%"
} else {
    // All are equal to "100%"
}

Live Example:

snippet.log("(true = at least one property is NOT 100%)");
test(1,
     {
      user_import_163: "100%",
      user_import_164: "99%"
     },
     true
);
test(2,
     {
      user_import_163: "100%",
      user_import_164: "100%"
     },
     false
);

function test(num, obj, expectedResult) {
  var result = Object.keys(obj).some(function(k) {
    return obj[k] !== "100%";
  });
  snippet.log(
    "Test #" + num +
    ": Got " + result +
    ", expected " + expectedResult + " <== " +
    (!result === !expectedResult ? "good" : "ERROR")
  );
}
