alert implements line breaks by using the br tag.
In HTML, to implement line breaks in the alert dialog box, you can use the br tag. The br tag indicates a line break, that is, starting a new line at this tag. The following is a simple example:
<!DOCTYPE html>
<html>
<head>
<style>
alert {
color: red;
font-size: 18px;
}
</style>
</head>
<body>
<script>
alert("这是一个警告框！\n这里开始新的一行。");
</script>
</body>
</html>In this example, we use the br tag in the alert dialog box to make "A new line starts here" appear on a new line in the dialog box. Note that the br tag is valid in both HTML and XML
, but in other markup languages you may need to use other methods to achieve line breaks.
