Question

我创建了一个带有推文按钮的简单报价机，可以发布报价。页面加载时，我会模拟＆＃34;新报价＆＃34;按钮被按下，所以推文按钮的网址会被引用更新，但在此之后，推文按钮在＆＃34;新报价＆＃34;之后不会使用新报价进行更新。按钮被按下。

HTML

<h1>Random Quote Generator</h1>

<p>These are some random quotes I found online by programmers. Enjoy!</p>

<button id="newQuote">New Quote</button>

<div id="quote"><span id="saying"></span><br/><i id="author"></i></div>

<a class="twitter-share-button" data-size="large" data-count="none">Tweet</a>

的Javascript

$(document).ready(function() {

window.twttr = (function(d, s, id) {
    var js, fjs = d.getElementsByTagName(s)[0],
    t = window.twttr || {};
    if (d.getElementById(id)) return t;
    js = d.createElement(s);
    js.id = id;
    js.src = "https://platform.twitter.com/widgets.js";
    fjs.parentNode.insertBefore(js, fjs);
    t._e = [];
    t.ready = function(f) {
        t._e.push(f);
    };
    return t;
}(document, "script", "twitter-wjs"));

$("#newQuote").on("click", function() {
    index = Math.floor(Math.random() * ((quotes.length-1) + 1));
    quote = quotes[index].split("/");
    $("#saying").text(quote[0]);
    $("#author").text(quote[1]);
    $('.twitter-share-button').attr("href", "https://twitter.com/intent/tweet?text=" + quote[0] + " " + quote[1]);
});
$("#newQuote").trigger("click");

)};

分隔

Answer 1

一个可能的问题是索引是全局范围的，因为缺少＆＃34; var索引......＆＃34;

你也应该使用.click（function（）{...}）;将onclick事件绑定到dom。

Answer 2

奇怪的是，在你的javascript底部，这两个字符是相反的。也许那就是它？

应该是
