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!

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

Is there any plugin similar to the iPad-like password field behaviour. We need to show only the focus number that the customer enters when they enter their credit card number, and then switch to a bullet once the customer types the next number.
For numbers that have been entered prior to the number being entered, they all need to be changed to the bullet style.
Not sure about Jquery plugin. tried this out. Hope this works for you - http://jsfiddle.net/Lhw7xcy6/12/

I'm to open pop-up windows BEHIND the current active screen using java script.
Here is my simple code.
var win = window.open('http://yahoo.com',null,"height=400,width=600,status=yes,toolbar=no,scrollbars=yes,menubar=yes,location=yes");
win.blur();
this.window.focus();
But it doesn't seems to be work in any browser. It simply opens a pop up.I referred this question from stackoverflow. But it doesn't work. My aim is to create a background window in all browsers. Someone help me please
You cannot do this. Modern web browsers do not allow websites to steal the focus from other tabs (because this could become quite messy for the users). The only thing that you could do is prompt your users to open in a new tab (which does not change the focus). Or you can abuse an alert to get the focus back to your page:
var win = window.open('http://yahoo.com',null,"target=_blank,height=400,width=600,status=yes,toolbar=no,scrollbars=yes,menubar=yes,location=yes");
alert("Welcome back");

Try to avoid triggering auto completing for the single key entry;Wait at least user enter three key board inputs.
And if your keep your key words in a static array it wont be affect to the speed of the page load.
But the size of your images, .css files, .js files will directly affect to speed of the page load.
try to compress those files and use light weight images.
And try to reduce the round trip time. In order to do that use your basic styling in your html page.
and do research in how to reduce the page load time.
and check your site with google developer page speed insights (https://developers.google.com/speed/pagespeed/insights/)
and read the tips.....
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.
