hello can any one guide me in my ajax request its always show me only eight record .
$(this).typeahead({
source: function (query, process) {
jQuery.ajax({
url: url + "/ajax/productdetail",
type: 'GET',
limit: 10,
data: {
cat: $type,
name: query,
form: $form,
setupid: $setupid
},
dataType: 'json',
success: function (response) {
objects = [];
map = {};
$.each(response, function (i, object) {
//debugger;
map[object.name] = object;
objects.push(object.name);
});
process(objects);
}
});
}
});
Just add an option "items" while instantiating the typeahead method. Hope the below sample will help you to understand.
$('input#auto-complete-field').typeahead({
minLength : 0,
items: 9999,
source: function (query, process) {
objects = [];
map = {};
$.ajax({
.......
......
});
}
updater: function(item) {
.............
.............
}
});

I have method that renders EJS templates and pass in the i18next.t function for the EJS template to do translations by setting the i18next t function as an attribute on the data object:
const data = {
email: user.email,
id: user.id,
t: i18nT
};
The data object is passed into ejs.renderFile(). The only way I can get the translation in the EJS template to work is when I set the i18nT variable to the t function from the i18next.init() functions call back. Otherwise it comes out blank. I see from the console output that the t function of the i18next instance, i18nInstance, is different to the t function set by the callback when initializing i18next.
function t() {
var _this$translator;
return this.translator && (_this$translator =
this.translator).translate.apply(_this$translator, arguments);
}
versus:
function () {
return _this4.t.apply(_this4, arguments);
}
Why is the t function of the i18nInstance object obtained from calling i18next.createInstance() different than the one from the callback? The one from the instance object doesn not work in the EJS template render.
The full code sample:
let i18nInstance: i18n;
let i18nT;
const i18nextInitOptions = {
backend: {
loadPath: path.join(__dirname, '/locales/{{lng}}/{{ns}}.json'),
addPath: path.join(__dirname, '/locales/{{lng}}/{{ns}}.missing.json')
},
debug: true,
fallbackLng: 'da',
preload: ['da', 'en', 'nl'],
returnEmptyString: false,
returnNull: false,
saveMissing: true
};
i18nInstance = await i18next
.createInstance();
await i18nInstance
.use(i18nextBackend)
.init(i18nextInitOptions, async function (error, t) {
if (error) {
console.log(error)
}
i18nT = t;
});
console.log("i18nT: " + i18nT)
/*
The console.log outputs below show that i18nT when set from the callback is different to the
i18nInstance.t.
i18nT: function () {
return _this4.t.apply(_this4, arguments);
}
*/
console.log("i18nInstance.t: " + i18nInstance.t)
/*
console output:
i18nInstance.t: function t() {
var _this$translator;
return this.translator && (_this$translator =
this.translator).translate.apply(_this$translator, arguments);
}
*/
const data1 = {
email: user.email,
id: user.id,
t: i18nT
};
// Calling htmlFromTemplate with data1 with t = i18nT the translation in the EJS template works.
html = await this.htmlFromTemplate('ejsTemplateName.ejs', data1);
const data2 = {
email: user.email,
id: user.id,
t: i18nextInstance.t
};
// Calling htmlFromTemplate with data2 with t = i18nextInstance.t the translation in the EJS is empty.
html = await this.htmlFromTemplate('ejsTemplateName.ejs', data2);
private htmlFromTemplate(templateName: string, data: Object): Promise<String> {
if (!templateName) return;
const htmlPath = path.join(__dirname, '../assets/mail-templates/' + templateName);
return new Promise((resolve, reject) => {
ejs.renderFile(htmlPath, data,(renderErr, str) => {
if (renderErr) {
appLogger.error('MAIL_RENDER: ' + renderErr, { templateName, data });
reject(renderErr);
} else resolve(str);
});
});
}
As soon as you pass the t function like this:
const data2 = {
email: user.email,
id: user.id,
t: i18nextInstance.t
};
the t function is not bound to its original "this" anymore...
pass it this way:
const data2 = {
email: user.email,
id: user.id,
t: i18nextInstance.t.bind(i18nextInstance)
};

I am using the Jquery file upload basic-plus.html. I am not sure How to use the Resumable uploading functionality in the below code.
I see something like this according to the documentation but not sure How to use that with the basic-plus.html
$('#fileupload').fileupload({
maxChunkSize: 10000000, // 10 MB
add: function (e, data) {
var that = this;
$.getJSON('server/php/', {file: data.files[0].name}, function (result) {
var file = result.file;
data.uploadedBytes = file && file.size;

I have the following JS method to bind the jQuery UI autocomplete widget to a search text box. Everything works fine, including caching, except that I make unnecessary server calls when appending my search term because I don't reuse the just-retrieved results.
For example, searching for "ab" fetches some results from the server. Typing "c" after "ab" in the search box fetches "abc" results from the server, instead of reusing the cached "ab" results and omitting ones that don't match "abc".
I went down the path of manually looking up the "ab" search results, filtering them using a regex to select the "abc" subset, but this totally seems like I'm reinventing the wheel. What is the proper, canonical way to tell the widget to use the "ab" results, but filter them for the "abc" term and redisplay the shortened dropdown?
function bindSearchForm() {
"use strict";
var cache = new Object();
$('#search_text_field').autocomplete({
minLength: 2,
source: function (request, response) {
var term = request.term;
if (term in cache) {
response(cache[term]);
return;
}
$.ajax({type: 'POST',
dataType: 'json',
url: '/get_search_data',
data: {q: term},
success: function (data) {
cache[term] = data;
response(data);
}
});
});
}
Here's my "brute-force, reinventing the wheel" method, which is, for now, looking like the right solution.
function bindSearchForm() {
"use strict";
var cache = new Object();
var terms = new Array();
function cacheNewTerm(newTerm, results) {
// maintain a 10-term cache
if (terms.push(newTerm) > 10) {
delete cache[terms.shift()];
}
cache[newTerm] = results;
};
$('#search_text_field').autocomplete({
minLength: 2,
source: function (request, response) {
var term = request.term.toLowerCase();
if (term in cache) {
response(cache[term]);
return;
} else if (terms.length) {
var lastTerm = terms[terms.length - 1];
if (term.substring(0, lastTerm.length) === lastTerm) {
var results = new Array();
for (var i = 0; i < cache[lastTerm].length; i++) {
if (cache[lastTerm][i].label.toLowerCase().indexOf(term) !== -1) {
results.push(cache[lastTerm][i]);
}
}
response(results);
return;
}
}
$.ajax({type: 'POST',
dataType: 'json',
url: '/get_search_data',
data: {q: term},
success: function (data) {
cacheNewTerm(term, data);
response(data);
return;
}
});
});
}
If anyone wants a version that supports multiple entries in the text box then please see below:
$(function () {
function split(val) {
return val.split(/,\s*/);
}
function extractLast(term) {
return split(term).pop();
}
var cache = new Object();
var terms = new Array();
function cacheNewTerm(newTerm, results) {
// keep cache of 10 terms
if (terms.push(newTerm) > 10) {
delete cache[terms.shift()];
}
cache[newTerm] = results;
}
$("#searchTextField")
.on("keydown",
function (event) {
if (event.keyCode === $.ui.keyCode.TAB &&
$(this).autocomplete("instance").menu.active) {
event.preventDefault();
}
})
.autocomplete({
minLength: 2,
source: function (request, response) {
var term = extractLast(request.term.toLowerCase());
if (term in cache) {
response(cache[term]);
return;
} else if (terms.length) {
var lastTerm = terms[terms.length - 1];
console.log('LAst Term: ' + lastTerm);
if (term.substring(0, lastTerm.length) === lastTerm) {
var results = new Array();
for (var i = 0; i < cache[lastTerm].length; i++) {
console.log('Total cache[lastTerm[.length] = ' +
cache[lastTerm].length +
'....' +
i +
'-' +
lastTerm[i]);
console.log('Label-' + cache[lastTerm][i]);
var cachedItem = cache[lastTerm][i];
if (cachedItem != null) {
if (cachedItem.toLowerCase().indexOf(term) !== -1) {
results.push(cache[lastTerm][i]);
}
}
}
response(results);
return;
}
}
$.ajax({
url: '#Url.Action("GetSearchData", "Home")',
dataType: "json",
contentType: 'application/json, charset=utf-8',
data: {
term: extractLast(request.term)
},
success: function (data) {
cacheNewTerm(term, data);
response($.map(data,
function (item) {
return {
label: item
};
}));
},
error: function (xhr, status, error) {
alert(error);
}
});
},
search: function () {
var term = extractLast(this.value);
if (term.length < 2) {
return false;
}
},
focus: function () {
return false;
},
select: function (event, ui) {
var terms = split(this.value);

I am doing the following stuff when a form is submitted. But I get this error:
Error decoding response: SyntaxError: syntax error
Here is my onSubmit success function:
onSubmit: function() {
var vals = this.form.getValues();
Ext.Ajax.request({
url: 'ticketSession.php',
jsonData: {
"function": "sessionTicket",
"parameters": {
"ticket": vals['ticket']
}
},
success: function( result, request ) {
var obj = Ext.decode( result.responseText );
if( obj.success ) {
//alert ('got here');
th.ticketWindow.hide();
Web.Dashboard.loadDefault();
}
},
Here is my ticketSession.php
<?php
function sessionTicket($ticket) {
if( $_REQUEST['ticket'] ) {
session_start();
$ticket = $_REQUEST['ticket'];
$_SESSION['ticket'] = $ticket;
echo("{'success':'true'}");
}
echo "{'failure':'true', 'Error':'No ticket Number found'}");
}
?>
I also modified my onsubmit function but didnt work:
Ext.Ajax.request({
url: 'ticketSession.php',
method: 'POST',
params: {
ticket: vals['ticket']
},
i am simply echoing this but I still get that error
echo("{'success':'true'}");
Maybe this can help you. It's a working example of an ajax-request which is nested in a handler.
var deleteFoldersUrl = '<?php echo $html->url('/trees/delete/') ?>';
function(){
var n = tree.getSelectionModel().getSelectedNode();
//FolderID
var params = {'folder_id':n['id']};
Ext.Ajax.request({
url:deleteFoldersUrl,
params:params,
success:function(response, request) {
if (response.responseText == '{success:false}'){
request.failure();
} else {
Ext.Msg.alert('Success);
}
},
failure:function() {
Ext.Msg.alert('Error');
}
});
}
I am currently having problem in using the jQuery API for
TextboxList
what i want is that to access the selected value in the Json array form, now the documentation suggest to use:
$('#form_tags_input').textboxlist();
but when i use it in the jQuery function on button click to get values using [getValues]
method it said undefined.
here is the javascript:
<script type="text/javascript">
$(function () {
// Standard initialization
var t = new $.TextboxList('#SentTo', { unique: true, plugins: { autocomplete: { minlength: 2, onlyFromValues: true}} });
//t.addEvent('bitBoxAdd', ContactAdded);
//t.addEvent('bitBoxRemove', ContactRemoved);
t.getContainer().addClass('textboxlist-loading');
$.ajax({
url: '/Home/GetContacts',
dataType: 'json',
success: function (r) {
t.plugins['autocomplete'].setValues(r);
t.getContainer().removeClass('textboxlist-loading');
}
});
});
function GetValues() {
var tblist = $('#SentTo').textboxlist();
alert(tblist.getValues());
return false;
}
function ContactAdded(e) {
//alert(e);
//GetValues();
return false;
}
function ContactRemoved(e) {
//alert(e);
}
i am using GetValues() function on button click to getvalues.
A help would be much appreciated.
Thanks.
Try to made TextboxLists "t" variable global
The changed code is:
$(function () {
// Standard initialization
t = new $.TextboxList('#SentTo', { unique: true, plugins: { autocomplete: { minlength: 2, onlyFromValues: true}} });
//t.addEvent('bitBoxAdd', ContactAdded);
//t.addEvent('bitBoxRemove', ContactRemoved);
t.getContainer().addClass('textboxlist-loading');
$.ajax({
url: '/Home/GetContacts',
dataType: 'json',
success: function (r) {
t.plugins['autocomplete'].setValues(r);
t.getContainer().removeClass('textboxlist-loading');
}
});
});
function GetValues() {
alert(t.getValues());
return false;
}
