如何將錶行索引傳遞給javascript函數

我有一些php代碼正在創建一個html表格。在它裏面我有一個表單，我有不同的下拉菜單，它們有onChange事件。我需要傳入javascript函數的錶行索引。有沒有辦法做到這一點？如果可以，請舉個例子。謝謝！如何將錶行索引傳遞給javascript函數

我的PHP代碼列表如下：

我已經把一個ID與元素的行號，這樣我就可以很容易地確定我是在哪一行。 – 2011-03-19 02:43:57

那麼我如何將它傳遞給我的函數呢？ – 2011-03-19 02:47:52

林使用到Zend的，所以這是多麼我通常做它，呼應的HTML isntead，只需鍵入出來的HTML，然後使用<?for:?>語法。如下所示。

雅我真的只需要一個數字，我的名字是在一個數組中。 – 2011-03-19 02:59:31

K我編輯，從它的20行看？ – Bodman 2011-03-19 03:05:21

是的，有20行。 – 2011-03-19 03:06:20

繼續其他答案：使用簡寫清除您的代碼。

然後注入循環數<?= $i ?>指示行數不同的速記

的

Remember <?= is the same as echo

一束IF/ELSE

<? if(true): ?> 

<? else: ?> 

<? endif; ?>

WHILE

<?php while (expr):?> 
    statement 
    ... 
<?php endwhile;?>

<?php for($i = 5; $i < 20; $i++):?>
