是否可以使用jQuery重命名按钮的名称，以根据按钮的名称执行不同的php脚本？

Question

I got a script with a navigation list (monday to sunday) and i wanna change a button's name depending on which day has "active"-class. I know how to select the element with the active class (and how to change the class). To receive the active class' name I use the following code:

var day=$('#navi ul li a.active').html();

But I was not able to change the name of the submit button. I tried this:

$('#loadStandard').name = $('#loadStandard').name + "_" + day;

This didnt change anything. I also tried:

$('#loadStandard').name= "bla";

but it didnt work. According to this it's the correct syntax. My form looks like this:

<form action="<?php echo plugins_url('plugin_directory/my_plugin.php'); ?>" method="post">
<input type="submit" name="loadStandard" class="loadStandard" id="loadStandard" value="Load standard values">
</form>

I want to change the name of the button so I can make different if statements in my php script. Kinda like this:

if (isset($_POST['loadStandard_monday'])) {
    do something;
}
elseif(isset($_POST['loadStandard_tuesday'])){
    do something else;
}

Is it even possible? What am I doing wrong? Please help me with some tips, links or code snippets!

Answer 1

Like the comments mention, you need to use .attr('name', day) .

Or may I suggest you just use a hidden value instead?

<input type="hidden" name="loadStandard[day]"  id="loadStandard_day" value="" />

---

$('#loadStandard_day').val(day);

<?php
if ($_POST['loadStandard']['day'] == '...')
    //...

Strange approach. You can do it like this:

var day=$('#navi ul li a.active').html(),
    submit_name = $('#loadStandard').attr('name');
$('#loadStandard').attr('name', submit_name+ "_" + day);

It will be better if you will use some hidden field:

<input type="hidden" name="day" id="id-day" value=""/>

var day=$('#navi ul li a.active').html();
    $('#id-day').val(day);

and on the server side:

switch($_POST['day']) {
   case "sunday":
      ...
      break;
   case "monday":
      ...
      break;
   ...
}
