jQgrid搜索返回子句不起作用的所有記錄

Question

我有一個簡單的jQgrid，帶有用於添加，編輯，刪除和搜索的工具欄（navGrid）。問題是搜索不起作用。它似乎總是返回表中的所有記錄，而不是一個，這意味着where子句有問題，我試圖根據搜索模式窗口中給出的內容生成。或者，它可能是搜索的情況下根本沒有被激活..

這裏是電網代碼：

$("#list").jqGrid({ 
     url: "server.php", 
     datatype: "json", 
     mtype: "POST", 
     colNames: ["Driver ID", "Name", "Country", "Victories", "Poles",  
"Titles", "Fastest laps"], //"Team name"], 
     colModel: [ 
      { name: "driverid", index:"driverid", width: 55, search:true,    stype:'text', editable:false}, 
     { name: "name", index:"name", width: 90, search:true, stype:'text', editable:true }, 
     { name: "country", index:"country", width: 90, search:true, stype:'text', editable:true }, 
     { name: "victories", index:"victories", width: 80, search:true, align: "right", editable:true }, 
     { name: "poles", index:"poles", width: 80, search:true, align: "right", editable:true }, 
     { name: "titles", index:"titles", width: 80, search:true, align: "right", editable:true }, 
     { name: "flaps", index:"flaps", width: 80, search:true, align: "right", editable:true} 
     //{ name: "teamName", width: 80, align: "right", editable:true} 
     ], 
     autowidth: true, 
     pager: "#pager", 
     rowNum: 10, 
     rowList: [10, 20, 30], 
     sortname: "driverid", 
     sortorder: "asc", 
     viewrecords: true, 
     gridview: true, 
     autoencode: true, 
     caption: "F1 statistics grid", 
     editurl: "dbedit.php" 
    }); 
jQuery("#list").jqGrid('navGrid','#pager',{add:true,del:true,edit:true,search:true}); 
}); 

這裏是dbedit.php部分：

include("connection.php"); //

// select the database 
mysql_select_db($database) or die("Error connecting to db.");

我已經完成了20次代碼，看看我是否輸入了錯誤的東西，但看不到它。是我在定義網格還是colModel時錯過的東西？

Answer 1

我已經失去了很多小時試圖弄清楚這一點。最後，我在網格代碼中加載了loadonce：true，並且它工作正常。所以，嘗試一下。把它放在任何地方，例如：viewrecords下：true
