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:

复制代码 代码如下:

var content = '
row 1
'
+ '
row 2
';

而不可以写成:

复制代码 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

  <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>
