我需要在 <a> 上调用 Javascript 函数元素click事件。当页面最初加载时，它将在 °C 中显示温度。 。稍后用户可以单击温度将其更改为 °C to °F反之亦然，无需刷新页面。
代码:
HTML:
<html>
<script src="https://use.fontawesome.com/51b73c8fb8.js"></script>
<body>
<div class="mainContainer">
<div class="tempOutCont">
<div class="tempInCont">
<span id="headDetails"></span>
<div id="iconTemp">
<img id="icon"></img>
<a id="unitLink" href="https://www.google.com"></a>
</div>
<span id="mainWeather"></span>
<span id="detailsHead">Details</span>
<div id="listDetails">
<ul>
<li>Wind<span id="windText" class="listDetailsItem"></span></li>
<li>Pressure<span id="pressureText" class="listDetailsItem"></span></li>
<li>Humidity<span id="humidText" class="listDetailsItem"></span></li>
<li>Cloudiness<span id="cloudText" class="listDetailsItem"></span></li>
</ul>
<div>
</div>
</div>
</div>
</body>
</html>
CSS:
html,

.mainContainer {
background-color: red;

#headDetails {

#iconTemp {

JS:
/*<iframe src="https://codepen.io/shaan046/full/jaggro/" allow="geolocation"></iframe>*/
var appId = "675645ead57721be136750f9cfc0acca";
var unit;
var temperature;
var changeUnit = function changeUnit(unit, temperature) {
console.log(unit);
if (unit === "C") {
temperature = temperature * 1.8 + 32;
unit = "F";
document.getElementById("unitLink").innerHTML = temperature + "°F";
} else if (unit === "F") {
temperature = (temperature - 32) / 1.8;
unit = "C";
document.getElementById("unitLink").innerHTML = temperature + "°C";
} else if (unit === "K") {
temperature = temperature - 273.15;
unit = "C";
document.getElementById("unitLink").innerHTML = temperature + "°C";
}
return false;
};
var getWeatherData = function getWeatherData() {
if (navigator.geolocation) {
navigator.geolocation.getCurrentPosition(function showPosition(position) {
var lat = String(position.coords.latitude);
var lon = String(position.coords.longitude);
$.ajax({
type: "GET",

appId,
success: function(json) {
document.getElementById("headDetails").innerHTML =
"Weather in " + json.name + "," + json.sys.country;
document.getElementById("icon").src =
"https://openweathermap.org/img/w/" + json.weather[0].icon + ".png";
changeUnit("K", json.main.temp);
document.getElementById("mainWeather").innerHTML =
json.weather[0].main;
document.getElementById("windText").innerHTML =
json.wind.speed + "m/s";
document.getElementById("pressureText").innerHTML =
json.main.pressure + "hpa";
document.getElementById("humidText").innerHTML =
json.main.humidity + "%";
document.getElementById("cloudText").innerHTML =
json.clouds.all + "%";
}
});
});
} else {
x.innerHTML = "Geolocation is not supported by this browser.";
}
};
$(document).ready(function() {
getWeatherData();
$("#unitLink").onclick = changeUnit(unit, temperature);
});
最佳答案
尝试使用 jQuery
$('#elementToChangeID').text("something");
关于javascript - 在 <a> 元素 onclick 事件上调用 Javascript 函数，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/47756059/
