用于在javascript变量中存储多行文本;
我正在使用PHP为javascript变量赋值。
请参阅下面的示例代码
<html>
<head>
<title> New Document </title>
<?php
$foo = " this is a
multiline statement";
?>
<script>
bar = '<?php print $foo;?>';
alert(bar);
</script>
</head>
<body>
</body>
</html>
我不想丢失任何空白字符。这怎么办?

var str = [
"Hello, this is a \n"
"multiline\n",
" string."
].join("");
或者,使用类似的技巧,
var str = [
"Hello, this ",
" is a multiline ",
"string separated by new lines ",
" with each array index"
].join("\n");

使用\n
打破该行。
<html>
<head>
<title> New Document </title>
<?php
$foo = " this is a \n
multiline statement";
?>
<script>
bar = '<?php print $foo;?>';
alert(bar);
</script>
</head>
<body>
</body>
</html>
如果您要将文字输出到浏览器,则必须使用<br />
而不是\n
。
