]]
"> </ Select>
2, the use of javascript create elements from the existing <select> or <input>.
<Input id = "cc" name = "dept" value = "01">
$ ( '# Cc'). Combogrid ({
panelWidth: 450,
value: '006',
idField: 'code',
textField: 'name',
url: 'datagrid_data.json',
columns: [[
{Field: 'code', title: 'Code', width: 60},
{Field: 'name', title: 'Name', width: 100},
{Field: 'addr', title: 'Address', width: 120},
{Field: 'col4', title: 'Col41', width: 100}
]]
});
AutoComplete feature
Let composite grid (combogrid) mention That AutoComplete feature. Drop-down data grid displays possible results based on user input.
$ ( '# Cc'). Combogrid ({
delay: 500,
mode: 'remote',
url: 'get_data.php',
idField: 'id',
textField: 'name',
columns: [[
{Field: 'code', title: 'Code', width: 120, sortable: true},
{Field: 'name', title: 'Name', width: 400, sortable: true}
]]
});
On the server side, 'q' parameter must first be retrieved. Users can query the database, and then returns a JSON format sql result to the browser.
get_data.php:
$ Q = isset ($ _ POST [ 'q']) $ _POST [ 'q']: ''; // the request parameter? // Query database and return JSON result data $ Rs = mysql_query ( "select * from item where name like '$ q%'"); echo json_encode (...);
