Question

这是我的代码：

现在，如何在会话中保存这些内容，以便每当我转到新链接时，该表仍然存在。多谢你们。

<body>

<script>
// Callback after window is loaded
if (window.addEventListener) {
  window.addEventListener("load", downloadFilesAtOnload, false);
} else if (window.attachEvent) {
  window.attachEvent("onload", downloadFilesAtOnload);
} else {
  window.onload = downloadFilesAtOnload;
}

function downloadFilesAtOnload() {
  // List of Javascript files to be loaded
  var jsFiles = ["js/library1.min.js", "js/library2.min.js", "CDN.library3.min.js"];
  loadScriptArray(jsFiles, function() {
    triggerEvent(document, 'scripts_loaded');
  });

  // List of CSS files to be loaded
  var robotoFonts = "https://fonts.googleapis.com/css?family=Roboto:400,300,300italic,400italic,500,500italic,700";

}

function loadScriptArray(contentArray, contentLoadedCallback){
  var contentQuantity = contentArray.length;      //Number of Files that needs to be loaded

      //The only way to know which script finished, is to pass the path as an parameter
      contentCompleted++;

        if (typeof contentLoadedCallback == 'function'){
          contentLoadedCallback();

      this.parentNode.removeChild(this);       //remove faulty node from DOM

    };
  }
  document.body.appendChild(element);              //insert the node in DOM (end of <head>), and load the script
}

在会话中存储$ row：

$_SESSION['rowdata'] = $row;

或者序列化$ row来存储它，并在你想要使用它时取消序列化：

//Store
$_SESSION['rowdata'] = serialise($row);

//get back
$row = unserialise($_SESSION['rowdata']);

如何保存表回显到会话？
