JQuery中的警报数据，用于循环PHP。

Question

I have a code which is in PHP Loop.

<?php for($i = 1; $i++; $i < 10) { ?>
<div class="test">
<textarea name="test-textarea" for="<?php echo $i ?>"></textarea>
<button value="<?php echo $i ?>">Save</button>
</div>
<?php } ?>

Now I want to alert data in JQuery. When I click button which value is 7 then it will alert data of textarea which is for value is 7.

Any Help will be Appreciated.

You can include the value of the button in an attribute selector, to find the linked textarea.

$('button').click(function(){
    alert( $('textarea[for="' + $(this).attr('value') + '"]').val() );
});

It would be better to use data-* attributes for your custom data.
