Есть ли способ избежать подтверждения повторной отправки формы? The page that you're looking for used information that you entered. Returning to that page might cause any action that you took to be repeated.Do you want to continue? Использование функции javascript или jquery любого типа, чтобы избежать повторной отправки формы?
function getComboB(sel) {
var invoices=document.getElementById("invoices");
var input_val = document.getElementById("invoices").value;
invoices.action = "searchinvoices.php?invoices="+input_val+"";
invoices.submit();
}
<table width="371" border="2">
<form name="invoices" id="invoices">
<tr>
<td width="160"><font class="font2"> Search By Invoice's Number:</font></td>
<td width="198"><input type="text" class="input_field" style="background:#FFF !important;" name="invoices" id="invoices" onchange="getComboB();" ></td>
</tr>
<tr>
<td colspan="2"> </td>
</tr>
</form>
</table>
