格式化多行文本到Js可用格式

PHP中文网Original: 2016-05-26 08:19:061616browse

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：

var content = 'dc6dce4a544fdca2df29d5ac0ea9906brow 116b28748ea4df4d9c2150843fecfba68'
+ 'dc6dce4a544fdca2df29d5ac0ea9906brow 216b28748ea4df4d9c2150843fecfba68';
而不可以写成：
var content = 'dc6dce4a544fdca2df29d5ac0ea9906b row 116b28748ea4df4d9c2150843fecfba68
dc6dce4a544fdca2df29d5ac0ea9906brow2 16b28748ea4df4d9c2150843fecfba68 ';
于是小加工一php小段代码，简化手工打的操作

    $rows       = explode("\n", $content);

        </form>
<h2>格式化后的结果：</h2>
<p class="content-box">
    <?php echo $jsContent;?>

    </body>
</html>
