如何从另一个jqgrid

标签： javascript php mysql jqgrid

我有一个jqgrid显示一个表的两个字段（测试）; ID字段和图片字段。在图片字段中，我从数据库中检索图像地址并在此字段中显示它们。这个jqgrid有多选属性。 1-我想从这个jqgrid中选择一些行，然后单击一个按钮从这些选定的行创建新的jqgrid。但是当我点击按钮而不是显示行this alert时。 2 - 当我想将此网格保存为仅保存的pdf图像地址（而不是图像）。 3 - 当我选择一些行时，“selr”变量包含此网格中的行的等级，而我需要selr包含所选行的“ID”。我的代码是：

//index.php
<!DOCTYPE html>
<html>
<head>
    <title>Insert selected row from grid1 to grid2</title>
    <link rel="stylesheet" type="text/css" media="screen" href="css/jquery-ui.css" />

    <style type="text">
        html, body {
            margin: 0;            /* Remove body margin/padding */
            padding: 0;
            overflow: hidden;    /* Remove scroll bars on browser window */
            font-size: 75%;
        }

    </style>
