Contoh yang sangat bagus di dokumen Autocomplete dengan kode sumber.
jQuery
<script>
$(function() {
function log( message ) {
$( "<div>" ).text( message ).prependTo( "#log" );
$( "#log" ).scrollTop( 0 );
}
$( "#city" ).autocomplete({
source: function( request, response ) {
$.ajax({
url: "http://gd.geobytes.com/AutoCompleteCity",
dataType: "jsonp",
data: {
q: request.term
},
success: function( data ) {
response( data );
}
});
},
minLength: 3,
select: function( event, ui ) {
log( ui.item ?
"Selected: " + ui.item.label :
"Nothing selected, input was " + this.value);
},
open: function() {
$( this ).removeClass( "ui-corner-all" ).addClass( "ui-corner-top" );
},
close: function() {
$( this ).removeClass( "ui-corner-top" ).addClass( "ui-corner-all" );
}
});
});
</script>
HTML
<div class="ui-widget">
<label for="city">Your city: </label>
<input id="city">
Powered by <a href="http://geonames.org">geonames.org</a>
</div>
<div class="ui-widget" style="margin-top:2em; font-family:Arial">
Result:
<div id="log" style="height: 200px; width: 300px; overflow: auto;" class="ui-widget-content"></div>
</div>
log.
success: function( data ) {response( data );} works inside the ajax call. I mean, what is that fungsi response () `? Ini membuat beberapa <li>elemen sesuai dengan data tetapi jika saya ingin menyesuaikan <li>elemen itu, apa yang harus saya lakukan? Saya ingin menambahkan sepasang atribut ...
Jika Anda mengembalikan objek json yang kompleks, Anda perlu mengubah fungsi sukses pelengkapan otomatis Anda sebagai berikut.
$.ajax({
url: "/Employees/SearchEmployees",
dataType: "json",
data: {
searchText: request.term
},
success: function (data) {
response($.map(data.employees, function (item) {
return {
label: item.name,
value: item.id
};
}));
}
});
Masalah saya adalah bahwa pengguna akhir akan mulai mengetik di kotak teks dan menerima saran pelengkapan otomatis (ACP) dan memperbarui kontrol panggilan jika saran dipilih karena ACP dirancang secara default. Namun, saya juga perlu memperbarui beberapa kontrol lainnya (kotak teks, DropDowns, dll ...) dengan data khusus untuk pilihan pengguna akhir. Saya telah mencoba mencari solusi elegan untuk masalah ini dan saya merasa solusi yang saya kembangkan layak untuk dibagikan dan semoga akan menghemat waktu Anda.
WebMethod (SampleWM.aspx):
TUJUAN:
CATATAN:
//Call to custom function to return SP results as a DataTable
// DataTable will consist of Field0 - Field5
Dim params As ArrayList = New ArrayList
params.Add("@QueryFilter|" & QueryFilter)
Dim dt As DataTable = Data.GetDataTableFromSP("AutoComplete", params, [ConnStr])
//Create a StringBuilder Obj to hold the JSON
//IE: [{"Field0":"0","Field1":"Test","Field2":"Jason","Field3":"Smith","Field4":"32","Field5":"888-555-1212"},{"Field0":"1","Field1":"Test2","Field2":"Jane","Field3":"Doe","Field4":"25","Field5":"888-555-1414"}]
Dim jStr As StringBuilder = New StringBuilder
//Loop the DataTable and convert row into JSON String
If dt.Rows.Count > 0 Then
jStr.Append("[")
Dim RowCnt As Integer = 1
For Each r As DataRow In dt.Rows
jStr.Append("{")
Dim ColCnt As Integer = 0
For Each c As DataColumn In dt.Columns
If ColCnt = 0 Then
jStr.Append("""" & c.ColumnName & """:""" & r(c.ColumnName) & """")
Else
jStr.Append(",""" & c.ColumnName & """:""" & r(c.ColumnName) & """")
End If
ColCnt += 1
Next
If Not RowCnt = dt.Rows.Count Then
jStr.Append("},")
Else
jStr.Append("}")
End If
RowCnt += 1
Next
jStr.Append("]")
End If
//Return JSON to WebMethod Caller
Return jStr.ToString
JQuery AutoComplete (AutoComplete.aspx):
$(function() {
$("#LookUp").autocomplete({
source: function (request, response) {
$.ajax({
type: "POST",
contentType: "application/json; charset=utf-8",
url: "SampleWM.aspx/GetAutoCompleteData",
dataType: "json",
data:'{QueryFilter: "' + request.term + '"}',
success: function (data) {
response($.map($.parseJSON(data.d), function (item) {
var AC = new Object();
//autocomplete default values REQUIRED
AC.label = item.Field0;
AC.value = item.Field1;
//extend values
AC.FirstName = item.Field2;
AC.LastName = item.Field3;
AC.Age = item.Field4;
AC.Phone = item.Field5;
return AC
}));
}
});
},
minLength: 3,
select: function (event, ui) {
$("#txtFirstName").val(ui.item.FirstName);
$("#txtLastName").val(ui.item.LastName);
$("#ddlAge").val(ui.item.Age);
$("#txtPhone").val(ui.item.Phone);
}
});
});
$(document).on('keyup','#search_product',function(){
$( "#search_product" ).autocomplete({
source:function(request,response){
$.post("<?= base_url('ecommerce/autocomplete') ?>",{'name':$( "#search_product" ).val()}).done(function(data, status){
response(JSON.parse(data));
});
}
});
});
Kode PHP:
public function autocomplete(){
$name=$_POST['name'];
$result=$this->db->select('product_name,sku_code')->like('product_name',$name)->get('product_list')->result_array();
$names=array();
foreach($result as $row){
$names[]=$row['product_name'];
}
echo json_encode($names);
}
Saya menggunakan konstruksi $.each (data [i], function (key, value)
Tapi Anda harus mencocokkan nama-nama bidang pemilihan dengan nama-nama elemen formulir. Kemudian, dalam loop setelah "berhasil", pelengkapan otomatis elemen dari larik "data". Lakukan ini: formulir pelengkapan otomatis dengan sukses ajax
Saya harap ini membantu:
var token = document.getElementById('token').value;
var nombre = document.getElementById('txtNombre').value;
$("#txtNombre").keyup(function () {
$.ajax({
type: "POST",
url: host() + "Formulario/BuscarNombreAutocompletar/",
data: JSON.stringify({ "nombre": nombre }),
headers: {
'Authorization': 'Bearer ' + token
},
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (data) {
var dataArray = [];
if (controlCarga(data)) {
$.each(data[1], function (i, item) {
dataArray.push(item.frmNombre)
});
$('#txtNombre').autocomplete({
clearButton: true,
source: dataArray,
selectFirst: true,
minLength: 2
});
}
},
error: function (xhr, textStatus, errorThrown) {
console.log('Error: ' + xhr.responseText);
}
});
});
