javascript - 在 while 循环中此赋值的逻辑（jshint 友好）等价物

Question

  dispose: function() {
    var disposer;
    while (disposer = this._disposers.shift()) { // expected a conditional expression and instead saw an assignment.
      disposer();
    }
  },

jshint不高兴在循环disposer中分配。while

有什么方法可以保持这种逻辑并使其jshint友好吗？

Answer 1

您可以简单地使用().

dispose: function () {
    var disposer;
    while ((disposer = this._disposers.shift())) {
        disposer();
    }
}

Answer 2

除非我错过了什么...

dispose: function() {
    var disposer = this._disposers.shift();
    while (disposer) {
        disposer();
        disposer = this._disposers.shift();
    }
},

你可能还想加强你的条件：

while (typeof disposer === 'function') {

Answer 3

dispose: function() {
  var disposer;
  while (typeof (disposer = this._disposers.shift()) === 'function') {
    disposer();
  }
},
