Here is the excel export.
saveAs(new Blob([s2ab(wbout)],{type:"application/octet-stream"}), Report-<?php echo $var?>.xlsx");

Answer 1

You can use query string to pass the value of clicked button
refer the "Today" button below.
You can set the value of variable "$var" to your execel or anything.
[Note:I done in the same page,create "test.php" and paste the following code and try,it will works well]
Thank You.
<?php
//Assume Variables $today and $this_week like below
$today = date('Y-m-d');
$this_week = "This week";
$var = "";
if(isset($_GET['getTday'])):
$str = $_GET['getTday'];
if($str == 'getToday')
{
$var=$today;
}
else
{
$var=$this_week;
}
endif;
echo $var;
?>
<div class="span3 btns_state">
<div data-toggle="buttons-radio" id="toggleButton" class="btn-group clearfix sepH_a" >
<button type="button" name="getTday" id="getToday" class="btn btn-info rep_data tip-bottom active" data-original-title="<?php echo $today;?>"onclick = "show('getToday')">Today</button>
<button type="button" name="getWeek" id="getWeek" class="btn btn-info rep_data tip-bottom" data-original-title="<?php echo $this_week;?>"onclick = "show()">This Week</button>
<button type="button" name="getMonth" id="getMonth" class="btn btn-info rep_data tip-bottom" data-original-title="<?php echo $this_month;?>"onclick = "show()">This Month</button>
<button type="button" name="getPreMonth" id="getpremon"class="btn btn-info rep_data tip-bottom" data-original-title="<?php echo $previous_month;?>"onclick = "show()">Last Month</button>
</div>
</div>
<script>
function show(val)
{
if(val == 'getToday')
{
location.href = "test.php?getTday=getToday";
}
}
</script>

Answer 2

Make button type submit with form tag
<form>
<button type="submit" name="getTday">
and so on...
</form>
Then you will get in php like $_GET['getTday'] this will get name attr of field so keep id and name same
else you need to use jquery/js to get id of button

Answer 3

add value attribute in your button like this value="getToday".
You can get this in php file.
Example
<button type="button" name="getTday" id="getToday" value="getToday" class="btn btn-info rep_data tip-bottom active" data-original-title="<?php echo $today;?>"onclick = "show()">Today</button>

Answer 4

Using jquery click event to perform your action. You have to remove all click event inside html
$(".btn.btn-info.rep_data.tip-bottom").click(function(){
var name=$(this).attr("name");
// you can get what ever it is
// this.id;
// this.value
});
DEMO
NOTE: Dont write event in html it is not good practis
