定義前使用的Jslint settimeout

Question

var AnimationManager = function (time, completionMethod) {
    "use strict";
    this.animationObjects = [];
    this.time = time;
    this.add = function (animationObject) {
        this.animationObjects.push(animationObject);
    };
    this.completionMethod = completionMethod;
    this.currentStage = 0;
    this.maximumStage = this.time * FPS;

    this.tick = function () {
        this.currentStage += 1;
        if (this.currentStage < this.maximumStage) {
            setTimeout(this.tick.bind(this), 1000.0 / FPS);
        } else {
            //Set manager to nil in the completion method
            this.completionMethod();
        }

        var i;
        for (i = 0; i < this.animationObjects.length; i += 1) {
            this.animationObjects[i].applyAnimation(this.currentStage);

        }
    };

    //Call this to start
    this.startAnimation = function () {
        this.timer = setTimeout(this.tick.bind(this), 1000.0 / FPS);
    };
};

括號中的JSLint給了我一些煩人的錯誤； 'setTimeout' was used before it was defined. setTimeout(this.tick.bind(this), 1000.0 / FPS);兩個類似的命令： 'setTimeout' was used before it was defined. setTimeout(this.tick.bind(this), 1000.0 / FPS); 'setTimeout' was used before it was defined. setTimeout(this.tick.bind(this), 1000.0 / FPS); 這到底是在說什么！

它還使用console.log來做到這一點。console是未定義的。

Answer 1

您必須告訴JSLint您的代碼在瀏覽器中運行，並且還需要假定已定義console 。

將其放在您的代碼之上：

/*jslint browser: true, devel: true */

老實說，我更喜歡JSHint這是少opiniated。
