to understand it better please see the error directly via google inspect at following page:

This error made my menus disabled and more issues. I would appreciate for any help to solve this error.

I am fairly certain this has been answered before here.
For normal javascript you can use:
window.innerHeight - the inner height of the browser window (in
pixels)
window.innerWidth - the inner width of the browser window (in
pixels)

Multi-level Accordion Menu: Its possible to open each level with an anchor?

I have a Multi-Level Accordion Menu - from a FAQ - with 2 levels.
Each level have a 13 Questions / Answers.
My problem:
One of the Questions/Answers have a lot of information. (almost 10 pages).
The other Questions/Answers have 3, 4 lines of information each.
The Question with many information is number 7.
Then When I click on question 7 - the answer 7 is open. with many information, and the user must scroll down the page to read all.
Until here, OK. no problem.
but at end - If I click on Question 8 - to read the answer, the menu closes question 7 (ok) - open question 8 (ok) - but the page still in the footer - the page dont scrolls up with the faq..
With all other questions - because they are small - I can see in same screen almost all 13 questions + the answer opened.
With question 7 - no. the page scrolls down and don't scrolls up - when we close the question 7.
There is a way to solve this? I think I need to create an anchor for each question..
Tks a lot!
https://jsfiddle.net/27sdLvmh/
Please, click on Question 7, scrool down to read the answer and then click on question 8. the menu scrolls up - but the screen no.. and the user was lost in the footer of the page.. :D

Text Field and Drop Down Combobox

I am new to javascript and am trying to add a combobox to a form I am creating, I would like the user to be able to enter an answer or pick one from a drop down. I found a pluggin online and set it up. The drop down works fine but the answer entered by the user isn't stored in the text field, when you click out of the text box it disappears.
I looking at the onblur part of the code to see if I could change the behavior but I couldn't. Could someone help? the code is below.
My HTML (I'm using Bootstrap)
<div class="col-md-4">
<div class="form-group">
<div class="input-group">
<label for="user_id" class="input-group-addon">User ID</label>
<select class="combobox input-large form-control" name="user_id" id="user_id">
<option value="" selected="selected">Enter ID</option>
<option value="ML">Multiple Users</option>
<option value="UN">Unknow User</option>
</select>
</div>
</div>
</div>
And the Javascript
!function( $ ) {
"use strict";

Binding the function to class 'combobox'
<script>
$(document).ready(function(){
$(\'.combobox\').combobox();
});
</script>

Try another plugin, like: https://github.com/steelheaddigital/jquery.ui.combify
To use it:
<select id="SomeSelect"></select>
$("#SomeSelect").combify()

First step is to add a return here
if (!this.selected && val !== '') {
return; /*
this.$element.val('');
this.$source.val('').trigger('change');
this.$target.val('').trigger('change');
*/
}
then see what that breaks.
I then did this
if (!this.selected && val !== '') {
console.log(val,this.source);
if (this.source.indexOf(val) ==-1) {
this.map[prompt("value to store for "+val+"?",val)]=val;
this.source.push(val)
}
return;
/*
this.$element.val('');
this.$source.val('').trigger('change');
this.$target.val('').trigger('change');
*/
}

Up/Down/Left/Right keyboard navigation with jQuery?

I have a list of div's all with a set and equal height/width that are float:left so they sit next to each other and fold under if that parent is smaller than the combined with of the items.
Pretty standard.
This is to create a list of the twitter bootstrap icons, it gives something like this:
I have added next/previous keyboard navigation using the code below, however you will notice that the up/down arrow keys are mapped to call the left/right functions. What I have no idea how to do is to actually do the up/down navigation?

Perhaps something like this: http://jsfiddle.net/QFzCY/
var blocksPerRow = 4;
$("body").on("keydown", function(e){
var thisIndex = $(".selected").index();
var newIndex = null;
if(e.keyCode === 38) {
// up
newIndex = thisIndex - blocksPerRow;
}
else if(e.keyCode === 40) {
// down
newIndex = thisIndex + blocksPerRow;
}
if(newIndex !== null) {
$(".test").eq(newIndex).addClass("selected").siblings().removeClass("selected");
}
});
Basically, you set how many items there are in a row and then find the current index and subtract or add that amount to select the next element via the new index.
If you need to know how many blocks per row there are, you could do this:
var offset = null;
var blocksPerRow = 0;
$(".test").each(function(){
if(offset === null) {
offset = $(this).offset().top;
}
else if($(this).offset().top !== offset) {
return false;
}
blocksPerRow++;
});
To deal with your 'edge' cases, you could do:
if(newIndex >= $(".test").length) {
newIndex = $(".test").length - newIndex;
}

moveUp: function () {
var that = this;
var index = $(this).index();
var containerWidth = parseInt( $('.select-icon-list').innerWidth(), 10);
var iconWidth = parseInt( $('.select-icon-list > a').width(), 10);
var noOfCols = Math.floor( containerWidth / iconWidth );
var newIndex = ( (index - noOfCols) < 0 ) ? index : (index - noOfCols);
var elem = $('.select-icon-list > a')[index];
},
Cache what ever remains static.

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.

http://github.com/istruble/jquery-autocomplete/commit/bdc926bd2c18c3ebab4e31463a8ae899fd761316#diff-1
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.
