是否有限制顯示字?jǐn)?shù)的功能啊

有！用truncate

從字符串開始處截取某長度的字符.默認(rèn)是80個(gè).

你也可以指定第二個(gè)參數(shù)作為追加在截取字符串后面的文本字串.該追加字串被計(jì)算在截取長度中。

默認(rèn)情況下,smarty會(huì)截取到一個(gè)詞的末尾。

如果你想要精確的截取多少個(gè)字符,把第三個(gè)參數(shù)改為"true"

CODE:

index.php:

$smarty =new Smarty;

$smarty->assign('articleTitle','Two Sisters Reunite after Eighteen Years at CheckoutCounter.');

$smarty->display('index.tpl');

www.2cto.com

index.tpl:

{$articleTitle}

{$articleTitle|truncate}

{$articleTitle|truncate:30}

{$articleTitle|truncate:30:""}

{$articleTitle|truncate:30:"---"}

{$articleTitle|truncate:30:"":true}

{$articleTitle|truncate:30:"...":true}

OUTPUT:

Two Sisters Reunite after Eighteen Years at Checkout Counter.

Two Sisters Reunite after Eighteen Years at Checkout Counter.

Two Sisters Reunite after...

Two Sisters Reunite after

Two Sisters Reunite after---

Two Sisters Reunite after Eigh

Two Sisters Reunite after E...
