我正在使用单独的 .js 文件更改某些文本的颜色。我是 HTML 和 JavaScript 的新手，请详细说明。谢谢。
这是我到目前为止得到的:
htmlfile.html
<html>
<body>
<p id="demo"> Click the button to change the text in this paragraph. </p>
</body>
</html>
jsfile.js
var button = document.createElement("button")
button.innerHTML = "Red or green"
// Sets or returns the content of an element
// 2. Append somewhere
var body = document.getElementsByTagName("body")[0]
body.appendChild(button)
// Adds a new child node, to an element, as the last child node
// 3. Add event handler
button.addEventListener("click", function () {
state = !state
// Attaches an event handler to the specified element
//var led = document.createElement('LED')
if (state = 1) {
document.getElementById("demo").style.color = "red"
} else {
document.getElementById("demo").style.color = "green"
}
//body.appendChild(led)
})
}
最佳答案
status = 1;
function switchStyle() {
x = document.getElementById("text");
if(status==1) {
x.style.color = 'blue';
status = 2;
}
else if(status==2) {
x.style.color = 'red';
status = 1;
}
}<p id="text">This text color will change.</p><br>
<button type="button" onclick="javascript:switchStyle();">Switch Style</button>关于javascript - 使用javascript更改html中文本的颜色，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/42544346/
