In my jquery autocomplete select function, I need to use the event.preventDefault() method to prevent the default ui.item.value from populating the input text box the autocomplete is wired too. This works great in Chrome, however in IE 8 (which is in use by a majority of our users) the .preventDefault() line throws the following error:
Unexpected call to method or property access
Here is the jQuery for good measure. Does anyone know of a work-around for this method in IE 8?
var tempResults = [];
$(function () {
$('#DRMCompanyName').autocomplete({
source: function (request, response) {
$.ajax({
url: '#Url.Action("compSearchByName", "AgentTransmission")',
type: 'GET',
dataType: 'json',
data: request,
success: function (data) {
tempResults = data;
response($.map(data, function (value, key) {
return {
label: value + " " + key,
value: key
};
}));
},
});
},
minLength: 2,
select: function (event, ui) {
event.preventDefault(); // <-Causing a problem in IE 8...
$('#DRMCompanyName').val(tempResults[ui.item.value]);
$('#DRMCompanyName').text(tempResults[ui.item.value]);
if ($('#DRMCompanyId').text() == '') {
$('#DRMCompanyId').val(ui.item.value);
$('#DRMCompanyId').text(ui.item.value);
}
}
});
});
You could use return false instead but as i said in comment: return false = event.preventDefault() + event.stopPropagation() But in your case, should fit your needs.

I am using this functionality to fill the JQuery UI with minimum length set to 2. This code works good when I try to select the list through mouse or through keyboard.
But once I publish my code through my virtual machine it does not work. Neither the minimum length works nor the mouse or keyboard selection works.
Please help me here.
function SPAutoComplete(request, response) {
//debugger;
$.ajax({
url: 'Contracts/SearchSpByNumber',
type: 'GET',
cache: false,
contentType: "application/json; charset=utf-8",
data: request,
dataType: 'json',
success: function (json) {
var i = 0;
i++;
// call autocomplete callback method with results
response($.map(json, function (item) {
return {
label: item.SP_NBR,
SPDesc: item.SP_DESC,
ID: item.ElementID
}
}));
},

//alert('error - ' + textStatus);
console.log('error', textStatus, errorThrown);
}
});

I am using select2 select box to populate and show some server data. Most of it works fine as I am able to get the results and populate the combo box. But when I type in the search box, the selection doesn't narrow down the the closest match.
I found the problem was because the backend URL doesn't support searching based on the string provided, while select2 keeps making multiple search request to backend, based on user entered text. The legacy backend code returns results in one shot, which is populated into the combobox the first time.
My question is, how do I get the the select box to focus to the closest matching result, without making multiple Ajax calls. I want the search to happen in the results which are already fetched.
Thanx to anyone helping me out on this.
My ajax call is like below, if this helps...
select2: {
placeholder: 'Select Next Plan Id',
allowClear: true,
id: function (item) {
return item.id;
},
ajax: {
type: 'GET',
dataType: "jsonp",
url: "http://172.16.7.248:8480/app/gui?action=1&type=11",
data: function (term, page) {
return { search: term };
},
results: function (data, page) {
return { results: data.aaData };
},
success : function(data, status, xhr) {
var html = "<option value=''>None</option>";
$.each(data.aaData, function(i, item) {
html += "<option data=" + JSON.stringify(item.id) + " value=" + item.id + "'>" + item.id + "</option>";
});
$('#nextplanid').html(html);
self.prop('data-loaded', 'true');
},
error : function(data, status, xhr) {
}
},
formatResult: function (item) {
return item.id;
},
formatSelection: function (item) {
return item.id;
},
initSelection: function (element, callback) {
return $.get('/getText', { query: element.val() }, function (data) {
callback(data);
});
}
},
I am using the jQueryUI autocomplete, have used it many times before, but I now have a more complex requirement.
I have a variable amount of Autocomplete fields to setup, using a JSON datasource and want to use an $().each to set these up. The problem appears to be the data: property of the AJAX call is always defaulting to values the final Autocomplete I setup.
$('[id$=CheckMethod]').each(function(index) {
if ($(this).val() === 'List') {
fieldToSetup = ($(this).attr('id').replace('txt',''));
fieldToSetup = left(fieldToSetup,(fieldToSetup.length - 11));
alert(fieldToSetup);
$('#txt' + fieldToSetup + 'CodeRoom' + escape(inRoomID)).autocomplete({
source: function (request, response) {
var src,
arrayData;
src = 'AJAXCheckCode.asp?actionType=List&GUID=' + $('#txtGUID').val();
$.ajax({
url: src,
datatype: 'json',
data: 'inCode=' + request.term + '&inType=' + $(this).attr('id'),
success: function (outData) {
arrayData = $.parseJSON(outData);
response($.map(arrayData, function (item) {
var theLabel = (item.Notes.length > 0) ? item.TheCode + ' - ' + item.Notes : item.TheCode;
return {
label: theLabel,
value: item.TheCode
};
}));
}
});
},
minLength: 1,
open: function (event, ui) {
$(".ui-slider-handle ui-state-default ui-corner-all").hide();
$(".ui-autocomplete.ui-menu").width(400);
$(".ui-autocomplete.ui-menu").css('z-index', 1000);
},
close: function (event, ui) {
$(".ui-slider-handle ui-state-default ui-corner-all").show();
},
focus: function (event, ui) {
return false;
},
select: function (event, ui) {},
search: function (event, ui) {
}
});
}
});//each CheckMethod
This code results in the 1st Autocomplete field using the inType parameter from the last field setup.
I'd rather not code for a maximum of 4 x 6 Autocomplete fileds and am trying to create one function to setup all the fields, is this possible?
Therefore my AJAX URL for my 1st Autocomplete looks like this
http://foo.com/AJAXCheckCode.asp?actionType=List&GUID={838138D6-A329-40F1-924B-58965842ECF8}&inCode=es&inType=A3&_=1335875408670
when "inType" should actually be A2, not A3 which is the last item of the outer $.each()
Hope this makes some sense!
Solved in the end by adding a class to the text box and then using live() on any text box with the given class that hasn't been bound before...works a charm
$('.foo:not(.ui-autocomplete-input)').live('focus', function(){
var fieldToReSource = ($(this).attr('id').replace('txt',''));
fieldToReSource = left(fieldToReSource,(fieldToReSource.length - 5));
$(this).autocomplete({
source: function (request, response) {
var src,
arrayData;
src = 'AJAXCheckCode.asp?inType=' + fieldToReSource + '&actionType=List&GUID=' + $('#txtGUID').val();
$.ajax({
url: src,
datatype: 'json',
data: 'inCode=' + request.term,
success: function (outData) {
arrayData = $.parseJSON(outData);
response($.map(arrayData, function (item) {
var theLabel = (item.Notes.length > 0) ? item.TheCode + ' - ' + item.Notes : item.TheCode;
return {
label: theLabel,
value: item.TheCode
};
}));
}
});
},

I'm trying to use jqueryui autocmplete with amplifyjs. Thats's to be able to switch between call to real server data and some hardcoded one and for additional flexibility.
For now I do not know how to make jqueryui autocomplete call amplify to refresh itself and perform search. I have the following codesnippet:
amplify.request.define('resId', 'ajax', {
url: 'autocmpleteUrl',
dataType: "json",
type: "POST"
});
$(elementId).autocomplete({
minLength: 1,
source: 'some url',
delay: 0,
focus: function (event, ui) {
$(elementId).val(ui.item.label);
return false;
},
select: function (event, ui) {
$(elementId).val(ui.item.label);
return false;
}
}).data("autocomplete")._renderItem = function (ul, item) {
return $("<li></li>")
.data("item.autocomplete", item)
.append("<a>" + item.label + "</a>")
.appendTo(ul);
};
I know in autocomplete part it can both be url and json data. But I can't figure out how to make it deal with amplify and make it so that if user inputs text jquery autocomplete requests amplify, not the url itself. Any ideas?
That's close to what you want, but you've forgotten to pass the search term to your request. Your code should be:
$( elem ).autocomplete({
source: function( request, response ) {
amplify.request( "resId", request, function( data ) {
response( data );
});
});
});
Which will send the search term as the term query parameter. Since you're doing a direct passthrough of the data, this can also be reduced:
$( elem ).autocomplete({
source: function( request, response ) {
amplify.request( "resId", request, response );
});
});
However, in both of these cases you're not handling errors, which means that you can leave the autocomplete in the search state indefinitely. You should use the full amplify.request form to handle errors:
$( elem ).autocomplete({
source: function( request, response ) {
amplify.request({
resourceId: "resId",
data: request,
success: response,
error: function() {
response( [] );
}
});
});
});
I've completed with the following solution:
autocomplete({
source: function(request, response){
amplify.request('resId', function(data){
response(data);
});
},
So you can provide a function to jquery.ui autocomplete and in this function just set the request object and autocomplete data will be filled with data you provide.
I have the following code and am curious as how to force the input to match the contents of the autocomplete:
$("#foo").autocomplete({
source: function( request, response ) {
$.ajax({
url: "index.pl",
dataType: "json",
data: {
type: 'foo',
term: request.term
},
success: function( data ) {
response( $.map( data.items, function( item ) {
return {
value: item.id
}
}));
}
});
},
minLength: 1
});
Answering this question for the benefit of anyone who stumbles upon this problem in 2013(yeah right!)
$("#my_input").autocomplete({
source: '/get_data/',
change: function(event, ui) {
var source = $(this).val();
var temp = $(".ui-autocomplete li").map(function () { return $(this).text()}).get();
var found = $.inArray(source, temp);
if(found < 0) {
$(this).val(''); //this clears out the field if non-existing value in <select><options> is typed.
}
}
});
Explanation:
The map() method creates a jQuery object populated with whatever is returned from the function (in this case, the text content of each <li> element).
The get() method (when passed no argument) converts that jQuery object into an actual Array.
Here is the original link of where I saw the solution.
I hope this helps. Thanks!
