使用JavaScript检查哈希中的所有值

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%?

Answer 1

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") ); }

Answer 2

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
