寫入HTML元素 (Writing into an HTML element)
To write string/text into an HTML element, we use the following things:
要將字符串/文本寫入HTML元素,我們使用以下內容:
There must be an HTML element like paragraph, span, div etc.
必須有一個HTML元素,例如段落,跨度,div等。
An HTML element must have an Id.
HTML元素必須具有ID。
We access the HTML element by using the id (to access an HTML element using Id, we use an HTML DOM method getElementbyId()).
我們使用id訪問HTML元素(要使用Id訪問HTML元素,我們使用HTML DOM方法getElementbyId() )。
Then, we write the text to the HTML element by using an HTML DOM property innerHTML.
然后,我們使用HTML DOM屬性innerHTML將文本寫入HTML元素。
Example:
例:
In this example, we have two paragraphs with p1 and p2 ids, we are writing two different texts in these HTML elements (paragraphs).
在此示例中,我們有兩個具有p1和p2 id的段落,我們在這些HTML元素(段落)中編寫了兩個不同的文本。
Example:
例:
<html>
<head>
<title>JavaScipt Example</title>
</head>
<body>
<p id="p1"></p>
<p id="p2"></p>
<script>
document.getElementById("p1").innerHTML = "Hello world!";
document.getElementById("p2").innerHTML = 10+20;
</script>
</body>
</html>
Output
