我正在尝试从JSON文件中检索引号及其作者,我遇到的问题是,一旦单击按钮一次,就会触发该事件,但之后仅触发一次。同样,当我调用$(document).ready()时,该按钮完全不会触发。
我知道这与我从JSON文件中收集数据(是一个带有文本,作者键的对象数组),然后在我想检索新报价时调用fetch的方式有关与正确的作者。
// https://type.fit/api/quotes //
// api link for quotes //
const button = document.getElementById('new-quote');
const baseUrl = 'https://type.fit/api/quotes';
let randomNumber = Math.floor(Math.random() * 100);
function getQuote() {
fetch(baseUrl)
fetch(baseUrl)
.then(response => response.json())
.then(quote => $('#text-output').text(quote[randomNumber].text))
};
function getAuthor() {
fetch(baseUrl)
.then(response => response.json())
.then(quote => $('#author').text(quote[randomNumber].author))
};
function renderQuoteToPage() {
getQuote();
getAuthor();
}
$('#new-quote').click(renderQuoteToPage);
$(document).ready(renderQuoteToPage);
body {
width: 100%;
height: auto;
}
#outer-wrapper {
display: flex;
flex-direction: row;
justify-content: center;
align-items: center;
}

<div class="card-body">
<div class="row">

<div id="text">
<p id="text-output"></p>
</div>
</div>
</div>
<div class="row">

在附加处理程序时,您正在调用函数,因此在没有附加适当的处理程序的情况下仅调用一次它们。
您只需要函数定义:
$('#new-quote').click(renderQuoteToPage);
...
$(document).ready(renderQuoteOnPageLoad);
编辑:您还需要在每个randomNumber
通话中设置getQuote()
// https://type.fit/api/quotes //
// api link for quotes //
const button = document.getElementById('new-quote');
const baseUrl = 'https://type.fit/api/quotes';
let randomNumber
function getQuote() {
randomNumber = Math.floor(Math.random() * 100);
fetch(baseUrl)
.then(response => response.json())
.then(quote => $('#text-output').text(quote[randomNumber].text))
};
function getAuthor() {
fetch(baseUrl)
.then(response => response.json())
.then(quote => $('#author').text(quote[randomNumber].author))
};
function renderQuoteToPage() {
getQuote();
getAuthor();
}
$('#new-quote').click(renderQuoteToPage);
$(document).ready(renderQuoteToPage);
body {
width: 100%;
height: auto;
}
#outer-wrapper {
display: flex;
flex-direction: row;
justify-content: center;
align-items: center;
}
