勾选输入框时，JavaScript会选中复选框-复选框数组[]

Question

I have a simple javascript issue. I have a checkbox and a input box.

when the user inputs text into an input box (onkeydown) I want it to check the corresponding checkbox in the row.

My checkbox's all share the same name for an array checkbox[] .

my simplified syntax is:

<table>
<?php if(isset($records)) : foreach ($records as $row) : ?>
    <tr>
        <td>
            <input type=checkbox name="editcustomer[]" id="editcustomer[]" value="<?php echo $row->id ?>">
        </td>
        <td>
            <input type="text" name="customer_name_<?php echo $row->id ?>" id="customer_name_<?php echo $row->id ?>" value="<?php echo $row->customer_name ; ?>" onclick="document.getElementById('editcustomer<?php echo $row->id ?>').checked = true;">
        </td>
    <tr>
<?php endforeach ; ?>
</table>

As the name of the checkbox is not unique, only the value thereof how do I tell the javascript which checkbox to check?

<input type="text" name="customer_name_<?php echo $row->id ?>" id="customer_name_<?php echo $row->id ?>" value="<?php echo $row->customer_name ; ?>" onclick="document.getElementById('editcustomer<?php echo $row->id ?>').checked = true;">

Help appreciated as always.

Thanks

HTML

<input type="checkbox" name="checkbox[]"/>
<input type="text" name="name1" id="name1" />
<br>
 <input type="checkbox" name="checkbox[]"/>
<input type="text" name="name2" id="name2" />
 <br>
 <input type="checkbox" name="checkbox[]" />
<input type="text" name="name3" id="name3" />

Jquery

$(':text').change(function(){
    $(this).prev(':checkbox').attr('checked','true');
});

Hope this helps. Regards.
