<script>
function removeAllRowsContainingCheckedCheckbox() {
  alert("hello");
    for (var rowi= table.rows.length; rowi-->0;) {
        var row= table.rows[rowi];
        var inputs= row.getElementsByTagName('input');
        for (var inputi= inputs.length; inputi-->0;) {
			//alert("inside for");
            var input= inputs[inputi];

            if (input.type==='checkbox' && input.checked) {
			//alert("indide if ")
                row.parentNode.removeChild(row);
                break;
            }
        }

＆＃13; 对于提交，我可以使用

编写javascript函数

$checkbox1=$_POST['techno'];  
    $chk="";  
    foreach($checkbox1 as $chk1)  
       {  
          $chk .= $chk1."";  
           echo '<script>alert("Inserted Successfully")</script>';
       }

上面的代码，因为if（isset（$ _ POST [＆＃39; sub＆＃39;]））正在重新加载表中已经提交的复选框，这样用户可能会在删除后混淆页面将再次显示所有复选框的那些人也提交..请为此建议替代方法我想将选中的复选框插入数据库，但我的想法是删除表中提交的已检查。

我可以使用outset（$ post []）为以下代码编写
