使用一个表单向不同的操作发送相同的输入

Question

I have two input fields and I want to post the same data to two different php files, depending on whatever button is clicked.

In my case the data is going into foo.php only, but not into excel.php.

I want the data to go to excel.php, if second button is pressed.

JS:

$(function() {

  $("#from").datepicker({
    defaultDate: "+1w",
    changeMonth: true,
    numberOfMonths: 3,
    onClose: function(selectedDate) {
      $("#to").datepicker("option", "minDate", selectedDate);
    }
  });

  $("#to").datepicker({
    defaultDate: "+1w",
    changeMonth: true,
    numberOfMonths: 3,
    onClose: function(selectedDate) {
      $("#from").datepicker("option", "maxDate", selectedDate);
    }
  });

});

HTML:

<form action="foo.php" method="post">
     <label for="from">From</label>
     <input type="text" id="from" name="from" />

     <label for="to">to</label>
     <input type="text" id="to" name="to" /> <br>

     <input type="submit" value="Viewchart">
</form>

<form action="excel.php" method="post">
     <input type="submit" value="Download Excel file">
</form>

You can change the action attribute when the button is clicked as follow:

$(function() { 
    $( ".actionable" ).click( function() {
        $('#myForm').attr('action', $(this).data("action"));
        $('#myForm').submit();
    });
});

And set the next data-* attributes to your buttons:

<form name="form" id="myForm" method="post">
    <input type="submit" class="actionable" value="Viewchart" data-action="foo.php"/>
    <input type="submit" class="actionable" value="Excel" data-action="excel.php"/>
</form>

You can see how it works here.

Clarification for OP:

The $( function() {} ); block —equivalent to $(document).ready( function() {} );— specify a function to execute when the DOM is fully loaded; you should put inside all your code which interact with the elements of the DOM.
