Question

我的网站上有2台打字机插件。两者都在同一个盒子里。首先，它只键入一个句子，第二个句子有4个句子，并且在第二个句子出现之前擦除一个句子。如何在第一台打字机完成后启动第二台打字机“类型”？

<script type="text/javascript">
$(function() {

    var text = $(".js-typewrite").text();
    var stop = text.length;
    var count = "0";
    $(".js-typewrite").text("");

    var type = function() {

        count++;
        if (count <= stop) {

            $(".js-typewrite").text(text.substr(0, count));

        } else {

            var write = clearInterval(type);

        }

    }

    var write = setInterval(type, 60);

});
</script>

<script type="text/javascript">
var TxtType = function(el, toRotate, period) {
    this.toRotate = toRotate;
    this.el = el;
    this.loopNum = 0;
    this.period = parseInt(period, 10) || 2000;
    this.txt = '';
    this.tick();
    this.isDeleting = false;
};

TxtType.prototype.tick = function() {
    var i = this.loopNum % this.toRotate.length;
    var fullTxt = this.toRotate[i];

    if (this.isDeleting) {
        this.txt = fullTxt.substring(0, this.txt.length - 1);
    } else {
        this.txt = fullTxt.substring(0, this.txt.length + 1);
    }

    this.el.innerHTML = '<span class="wrap">' + this.txt + '</span>';

    var that = this;
    var delta = 100 - Math.random() * 100;

    if (this.isDeleting) {
        delta /= 2;
    }

    if (!this.isDeleting && this.txt === fullTxt) {
        delta = this.period;
        this.isDeleting = true;
    } else if (this.isDeleting && this.txt === '') {
        this.isDeleting = false;
        this.loopNum++;
        delta = 500;
    }

    setTimeout(function() {

        that.tick();
    }, delta );




};

window.onload = function() {
    var elements = document.getElementsByClassName('typewrite');
    for (var i = 0; i < elements.length; i++) {
        var toRotate = elements[i].getAttribute('data-type');
        var period = elements[i].getAttribute('data-period');
        if (toRotate) {
            new TxtType(elements[i], JSON.parse(toRotate), period);
        }
    }
    // INJECT CSS
    var css = document.createElement("style");
    css.type = "text/css";
    css.innerHTML = "";
    document.body.appendChild(css);
};
</script>

Answer 1

使用setTimeout来延迟并在时间间隔之后调用一个函数。

语法：

setTimeout(function(){
//your code here
})},2000);

// 2000是2秒延迟

Answer 2

如果您使用的是jQuery，请尝试使用jQuery.defered或defered.promise

在另一个插件之后加载一个javascript插件
