Question

我有一个问题，我正在设计一个网页来处理数据库。所以这个想法是，

我有一个下拉列表
当用户点击选项时，
直接打开包含其他网页的新窗口
在新页面上，使用dropdown

$_POST

问题是，当我单击该选项时，它会重定向到该新页面，但不会以新窗口的形式重定向。如何使用

$newVal = strval($_POST['PROJECT_NAME']);

我的代码是，

<script>
            $(function(){
              $('#cd-dropdown').bind('change', function () {
                  var url = $(this).val(); // get selected value
                  if (url) { // require a URL
                      window.location = "monitorIndex.php"; // redirect
                  }
                  return false;
              });
            });
        </script>

标记：

$projectParse = oci_parse($conn, 'SELECT DISTINCT PROJECT_NAME FROM MASTER_DRAWING '
                                        . 'ORDER BY PROJECT_NAME ASC');
                                oci_execute($projectParse);

                                echo '<select name="cd-dropdown "id="cd-dropdown" class="cd-select">';
                                    echo '<OPTION VALUE="">PROJECT SELECT</OPTION>';
                                    while($row = oci_fetch_array($projectParse,OCI_ASSOC)){
                                        $projectName = $row ['PROJECT_NAME'];
                                        echo "<OPTION VALUE='$projectName'>$projectName</OPTION>";
                                    }
                                echo '</select>';

Answer 1

试试这个。

$('#cd-dropdown').change(function(){
    var id = $(this).val();
    window.location = 'monitorIndex.php?id=' + id;
});

Answer 2

    This method should take you to new window with ProjectName in URL. 

    $('#dropdown').change(function(){
        var id = $(this).val();
        window.open ('monitorIndex.php?id=' + id ,'_blank');
    });



 Or another way is if you are using HTML5 , you can use local storage,
 You can basically keep the value on client side localstorage and can access it on any other page.

// Store
localStorage.setItem("projectname", "abc");
// Retrieve
document.getElementById("result").innerHTML = localStorage.getItem("projectname");

Answer 3

尝试以下代码

$('#cd-dropdown').change(function(){
    var id = $(this).val();
    $.ajax({
      type: "POST",
      url: "monitorIndex.php",
      data: { PROJECT_NAME: id }
    })
  .done(function( msg ) {
      var myWindow = window.open("", "MsgWindow", "width=800, height=800");
      myWindow.document.write(msg );
   });
 });

选择Dropdown onChange选项
