JQuery Autocomplete/Autosearch Textbox
Dec 16 2019 7:42 AM
Dear Team,
I want to implement an Autocomplete / Autosearch textbox in normal web page.
I have tried all the methods, but I get only 1 error -
0x800a01b6 - JavaScript runtime error: Object doesn't support property or method 'autocomplete'
My Code -
<%@ Page Language=
"VB"
AutoEventWireup=
"false"
CodeFile=
" frmManageAdmission.aspx.vb"
Inherits=
" frmManageAdmission"
%>
<!DOCTYPE html PUBLIC>

<body>
<form id=

$(document).ready(
function
() {
$(
"#<%=txtFirstName.ClientID%>"
).autocomplete({
source:
function
(request, response) {
$.ajax({
url:
'<%=ResolveUrl("~/frmManageAdmission.aspx/GetFirstNames") %>'
,
data:
"{ 'prefixText': '"
+ request.term +
"'}"
,
dataType:
"json"
,

function

response($.map(data.d,
function
(item) {
return
{
label: item.split(
'-x-'
)[1],
val: item.split(
'-x-'
)[0]
}
}))
},
error:
function
(response) {
alert(response.responseText);
},
failure:
function
(response) {
alert(response.responseText);
}
});
},
select:
function
(e, i) {
$(
"#<%=hdnfldFirstName.ClientID%>"
).val(i.item.val);
},
minLength: 2
});
});
