恭喜您成為首批注冊(cè)用戶
獲得88經(jīng)驗(yàn)值獎(jiǎng)勵(lì)
本節(jié)將會(huì)向jQuery EasyUI數(shù)據(jù)網(wǎng)格(datagrid)中添加查詢功能。
以下實(shí)例演示如何從數(shù)據(jù)庫(kù)得到數(shù)據(jù),并將它們顯示在數(shù)據(jù)網(wǎng)格中,然后演示如何根據(jù)用戶輸入的搜索關(guān)鍵詞搜尋顯示結(jié)果。
創(chuàng)建帶有分頁(yè)功能的數(shù)據(jù)網(wǎng)格(datagrid),然后添加工具欄到其中。
<table id="tt" class="easyui-datagrid" style="width:600px;height:250px" url="datagrid24_getdata.php" toolbar="#tb" title="Load Data" iconCls="icon-save" rownumbers="true" pagination="true">
<thead>
<tr>
<th field="itemid" width="80">Item ID</th>
<th field="productid" width="80">Product ID</th>
<th field="listprice" width="80" align="right">List Price</th>
<th field="unitcost" width="80" align="right">Unit Cost</th>
<th field="attr1" width="150">Attribute</th>
<th field="status" width="60" align="center">Stauts</th>
</tr>
</thead>
</table>
工具欄定義如下:
<div id="tb" style="padding:3px">
<span>Item ID:</span>
<input id="itemid" style="line-height:26px;border:1px solid #ccc">
<span>Product ID:</span>
<input id="productid" style="line-height:26px;border:1px solid #ccc">
<a href="#" class="easyui-linkbutton" plain="true" onclick="doSearch()">Search</a>
</div>
當(dāng)用戶輸入查詢值并按下查詢按鈕時(shí),'doSearch'函數(shù)將被調(diào)用:
function doSearch(){
$('#tt').datagrid('load',{
itemid: $('#itemid').val(),
productid: $('#productid').val()
});
}
上面的代碼調(diào)用了'load'方法來(lái)加載新的數(shù)據(jù)網(wǎng)格(datagrid)數(shù)據(jù)。我們需要傳遞'itemid'和'productid'參數(shù)到服務(wù)器。
include 'conn.php';
$page = isset($_POST['page']) ? intval($_POST['page']) : 1;
$rows = isset($_POST['rows']) ? intval($_POST['rows']) : 10;
$itemid = isset($_POST['itemid']) ? mysql_real_escape_string($_POST['itemid']) : '';
$productid = isset($_POST['productid']) ? mysql_real_escape_string($_POST['productid']) : '';
$offset = ($page-1)*$rows;
$result = array();
$where = "itemid like '$itemid%' and productid like '$productid%'";
$rs = mysql_query("select count(*) from item where " . $where);
$row = mysql_fetch_row($rs);
$result["total"] = $row[0];
$rs = mysql_query("select * from item where " . $where . " limit $offset,$rows");
$items = array();
while($row = mysql_fetch_object($rs)){
array_push($items, $row);
}
$result["rows"] = $items;
echo json_encode($result);
