How to fix Javascript no longer working after converting to core 2.2

I convert an application from Core 1.1 to 2.2. Now some of my JS is not working
After conversion I noticed that my columns were no longer sorting when I clicked on them. I added some JS code and now it works. This is when I found that there was a custom JS lib with the sorting code in there but it no longer worked.
I also found that the filtering (client side) is not working.
I converted the code following the instructions in https://learn.microsoft.com/en-us/aspnet/core/migration/1x-to-2x/?view=aspnetcore-1.1
Here is the JS script to perform the filtering.
(function ($) {
$.fn.appgrid = function appgrid() {
function configureFilter() {
$("[data-update-departments]").on("change", function () {
var triggerControl = $(this);
var connectedControl = $(triggerControl.data("update-departments"));
if (!connectedControl.data("default")) {
connectedControl.data("default", connectedControl.children());
}
var triggerValue = triggerControl.find(":selected").val();
if (triggerValue) {
$.getJSON("/ManageNomination/GetDepartments?company=" + triggerValue, function (data) {
if (data) {
connectedControl.children().remove();
connectedControl.append('<option value=""></option>');
for (var i = 0; i < data.length; i++) {
connectedControl.append('<option value="' + data[i] + '">' + data[i] + '</option>');
}
connectedControl.removeAttr("disabled");
}
});
} else {
connectedControl.children().remove();
connectedControl.attr("disabled", "disabled");
}
})
$("#applyFilter").on("click", function () {
filter = $.extend({}, defaultFilter);
$("[id^=filter-]").each(function () {
var control = $(this);
var controlId = control.attr("id").substr(7);
if (this.type === "text" || this.type === "date") {
filter[controlId] = control.val();
} else if (this.type === "select-one") {
filter[controlId] = control.find(":selected").val();
}
});
localStorage.setItem('filter', JSON.stringify(filter));
refreshData();
$("#filter-applied-message").show();
});
$(".clearFilter").on("click", function () {
filter = $.extend({}, defaultFilter);
localStorage.removeItem('filter');
localStorage.removeItem('currentPage');
refreshData();
$("#filter-applied-message").hide();
setFilterControlValues();
});
setFilterControlValues();
}
function setFilterControlValues() {
// repopulate the filter fields with the saved filter values
$("[id^=filter-]").each(function () {
var control = $(this);
var controlId = control.attr("id").substr(7);
control.val(filter[controlId] || defaultFilter[controlId] || "");
if (this.type === "select-one" && control.data("update-departments")) {
if (control.find(":selected").val()) {
// control is a connected dropdown and has a selected value
$(control.data("update-departments")).removeAttr("disabled");
} else {
$(control.data("update-departments")).attr("disabled", "disabled");
}
}
// open the filter panel automatically
//$(".filterPanel").collapse("show");
});
}
So the dropdowns for the filtering are populated but when I select a value to filter on, nothing happens.

Setup jqueryui before element is rendered

In creating a table cells with very cool options I need to take two steps. First I create the table cell as a DOM object in javascript with all the 'normal' functionality, like is it a checkbox, a select, an input, a link, etc.
Then I need to put the table on the page to do the next step, which I consider advanced functionality like jqueryui's autocomplete and date select. It is awesome to have these drop downs for the user.
I do have this working, however, I do need to make two calls. The first to createTableCell, then I render, then I need to make another call to postRenderTableFunctions to get the autocomplete functionality working. So the question is, why the second call, what is it about jqueryui that will not work on the first call. You can see the commented section under input creation where I tried to get the autocomplete working.
function createTableCell(name, td_def)
{
var cell=document.createElement('td');

My original comment to your question -
I suspect i may work if you replace
$( "#" + name ).autocomplete({
with
$(element).autocomplete({
though I don't currently have means to test it.
My response -
Basically using $("#name") looks for an element with the ID name in the DOM. When you are running your code element has not been added to the DOM yet so the autocomplete cannot be attached to to your element.
Surrounding element with $() converts it to a jQuery variable which you can attach the autocomplete to before it is added to the DOM.

jQuery .hide(), then .show() based on text input

Using a jQuery filter example I found. Here is my live example. Here is the CodePen, (also the Fiddle if you don't like CodePen).
After typing something in the input, the boxes do realign and the numbers dissapear. However, when you delete the text you inputted, the numbers do not reappear unless you refresh the page. I tried messing around with the code below but wasn't having any luck. Thanks for you help!
$('#sortable').change(
function(){
if ($(this).val().length) {
$('#number').hide();
}
else {
$('#number').show();
}
});

Try this out:- http://jsfiddle.net/adiioo7/nYYBU/10/
JS:-
(function ($) {
jQuery.expr[':'].Contains = function (a, i, m) {
return (a.textContent || a.innerText || "").toUpperCase().indexOf(m[3].toUpperCase()) >= 0;
};
function listFilter(header, list) {
var form = $("<form>").attr({
"class": "filterform",
"action": "#"
}),
input = $("<input>").attr({
"class": "filterinput",
"type": "text",
});
$(form).append(input).appendTo(header);
$(input).change(function () {
var list = $("#sortable");
var filter = $(this).val();
console.log(filter.length);
if (filter.length > 0) {
$(list).find("a:not(:Contains(" + filter + "))").parent().slideUp();
$(".number").hide();
$(".numberstwo").hide();
} else {
console.log($(".number"));
$(".number").show();
$(".numberstwo").show();
$(list).find("a").parent().slideDown();
}
return false;
}).keyup(function () {
$(this).change();
});
}
$(function () {
listFilter($("#header"), $("#sortable"));
});
}(jQuery));

Here's updated js...
Checkout Demo Fiddle
(function ($) {
jQuery.expr[':'].Contains = function (a, i, m) {
return (a.textContent || a.innerText || "").toUpperCase().indexOf(m[3].toUpperCase()) >= 0;
};
function listFilter(header, list) {
var form = $("<form>").attr({
"class": "filterform",
"action": "#"
}),
input = $("<input>").attr({
"class": "filterinput",
"type": "text",
});
$(form).append(input).appendTo(header);
$(input).change(function () {
var filter = $(this).val();
if (filter) {
$(list).find("a:not(:Contains(" + filter + "))").parent().slideUp();
$(list).find("a:Contains(" + filter + ")").parent().slideDown();
} else {
$(list).find("li").slideDown();
}
return false;
}).keyup(function () {
$(this).change();
if ($(this).val().length) {
$('.number').hide();
} else {
$('.number').show();
}
});
}
$(function () {
listFilter($("#header"), $("#sortable"));
});
}(jQuery));

To check the entered text I normally use keyup.
Change is not triggered when the user types something but when he types and exits the box.

$('#sortable').blur(function(){
var len = $(this).val().length;
if (len) {
$('#number').hide();
}
else {
$('#number').show();
}

JQuery AutoComplete Append to Open List

I tested the JQuery autocomplete UI widget and noticed that the autocomplete has extremely poor performance in IE when dealing with large amount of data. My client uses internet explorer 7.
I found a solution to mitigate the performance issue. Instead of returning all the matches of the autocomplete search I only return the first 40 matches. Code below
source: function (request, response) {
var matcher = new RegExp("^" + $.ui.autocomplete.escapeRegex(request.term), "i");
var select_el = select.get(0); // get dom element
var rep = new Array(); // response array
var maxRepSize = 40; // maximum response size
// simple loop for the options
var looper = 0;
for (var i = 0; i < select_el.length; i++) {
var text = select_el.options[i].text;
if (!request || request == '') {
// add element to result array
rep[looper++] = {
label: text,
value: text,
option: select_el.options[i]
};
}
else if ( select_el.options[i].value && matcher.test(text) ) {
// add element to result array
rep[looper++] = {
label: text,
value: text,
option: select_el.options[i]
};
}
if ( rep.length > maxRepSize ) {
needMoreItems = true;
break;
}
}
// send response
response( rep );
},
The client asked me to append a "More Results" item to the autocomplete list. If there were more than 40 items that matched the search the "More Results" item would appear of at the bottom of the list. If a user clicked on the "More Results" item, the autocomplete drop down would expand to include the next 40 matches. I experimented with the jQuery autocomplete and I was able to populate the auto suggest list with the next 40 items but when the user clicked on one of the dynamically added items, I could not bind the click event to the Select Event of the autocomplete UI widget. Code below:
open: function( event, ui ) {
if (needMoreItems) {
needMoreItems = false;
$('<li class="ui-menu-item" role="menuitem" id="yoADDMORE" ><a class="ui-corner-all" tabindex="-1">... more available<br/><br/></a></li>')
.bind({
click: function(e) {
var appendHtml = '';
var select_el = select.get(0);
var maxRepSize = 40; // maximum response size
// simple loop for the options
var looper = 0;
for (var i = 41; i < select_el.length; i++) {
appendHtml += '<li class="ui-menu-item" role="menuitem"><a class="ui-corner-all" tabindex="-1">' + select_el.options[i].text + '</a></li>';
if ( looper ++ > maxRepSize ) {
needMoreItems = true;
break;
}
}
if (needMoreItems)
appendHtml += '<li class="ui-menu-item" role="menuitem" id="yoADDMORE" ><a class="ui-corner-all" tabindex="-1">... more available<br/><br/></a></li>';
$('#yoADDMORE').remove();
$('ul.ui-autocomplete').html($('ul.ui-autocomplete').html() + appendHtml);
$('ul.ui-autocomplete > li')
.bind({
mouseenter: function(e) {
// Hover event handler
$("> a",this).attr('class','ui-corner-all ui-state-hover');
},
mouseleave: function(e) {
// Hover event handler
$("> a",this).attr('class','ui-corner-all');
}
});
},
mouseenter: function(e) {
// Hover event handler
$("> a",this).attr('class','ui-corner-all ui-state-hover');
},
mouseleave: function(e) {
// Hover event handler
$("> a",this).attr('class','ui-corner-all');
}
})
.appendTo('ul.ui-autocomplete');
}
},

Problem with jquery.ui.autocomplete.js on IE7

Here is the code. IE7 spouts an "'active.0' is null or not an object" error on line 39, which is:
input.trigger("activate.autocomplete", [$.data(active[0], "originalObject")]); $("body").trigger("off.autocomplete");
Works perfectly in Firefox/Chrome/Opera. Any ideas? Many thanks and much appreciated.

It is a version of jquery.ui.autocomplete.js with most of the IE 7 issues fixed. I found a few more issues which I listed at the bottom along with how to fix them.

Here is my code that works javascript first:
$(".student_search").autocomplete("student_search.php", {
minChars: 2,
cacheLength: 20,
matchContains: true,
highlightItem: true,
parse: function(data) {
return $.map(eval(data), function(row) {
return {
data: row,
value: row.studentname, //value being searched for
result: row.studentidnumber //value in text input
}
});
},
formatItem: function(row, i, max, term) {
return "<span style='font-size: 110%;'>" + row.studentname + "</span><br/>" + "ID: " + row.studentidnumber + ", " + " Grade: " + row.studentgradenumber;
},
formatResult: function(row, i, max){
return row.studentidnumber;
}
});
});
Here is the code in the PHP file. It prints a JSON object with the data.
if(isset($_GET['q'])){
require_once("php/mysql.connect.php");
$request = strtolower($_GET['q']);
$query = mysql_query("SELECT
CONCAT(studentfname, ' ', studentlname, '')
AS studentname, studentidnumber,
CONCAT(studentgradenumber, 'th')
AS studentgradenumber
FROM studentinfo
WHERE studentlname LIKE '%".$request."%'
OR studentfname LIKE '%".$request."%'
OR studentidnumber LIKE '%".$request."%'") or die(mysql_error());
$results = array();
$i = 0;
while($row = mysql_fetch_assoc($query)) //fetch each result using the column name as the array key
{
foreach($row as $column=>$val) //loop through each column
{
$results[$i][$column] = $val; //build array using incremental row # and column name
}
$i++; //increase the row counter
}
print json_encode($results);
}
The JSON object that is printed is:
[{"studentname":"Joe Schmo","studentidnumber":"123456","studentgradenumber":"11th"}]
so row.studentname returns Joe Schmo. Where row is the name of the variable in the function and studentname is the name of the key from the JSON object.
Cheers!

I had problems with autocompletion of jquery ui version 1.8.9 and IE7. I use 1.8.16 now and it works.
