php实现格式化多行文本为Js可用格式_PHP

js里现在存写模板的场景好多，如：弹框类的html代码模板等，js不支持换行的长文本写法，必需要一行行的加起来，如：

代码如下:


var content = '

row 1
'
+ '
row 2
';

而不可以写成：

代码如下:


var content = '

row 1

row2
';

于是小加工一php小段代码，简化手工打的操作。

tojs.php

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html lang="en">
  <head>
   <meta http-equiv="Content-Type" content="text/html;charset=UTF-8">
   <title>Str To Js String</title>
    <style type="text/css">
.content-box { border: 1px #f0f0f0 slid; border-left: 4px #e0e0e0 solid; padding: 5px 5px 5px 10px; }
</style>
  </head>
  <body>
<h1>输入格式化的文本：</h1>
<&#63;php 
$jsContent = '';
if(isset($_POST['content']) && $_POST['content']) { 
  $content  = strtr(htmlspecialchars($_POST['content']), array("\r\n" => "\n"));
  $rows    = explode("\n", $content);
  foreach($rows as $row) {
    $jsContent .= '+ \'' . $row . "'<br/>";
  }
  $jsContent{0}  = ' ';
} 
&#63;>
    <form action="#" method="post">
      <textarea name="content" style="width: 99%;height: 300px; "></textarea>
      <p><input type="submit" value="提交" /></p>
    </form>
<h2>格式化后的结果：</h2>
<div class="content-box">
  <&#63;php echo $jsContent;&#63;>
</div>
  </body>
</html>
