I have left the arrLot array alone for now. But this is my guess at what your code needs to be.
Basically I convert arrIns array to one big string, then compare sub-strings with i. If the value of i isn't found then arr[ ] = i

JavaScript

// **NEW** add leading zero to numbers < 10
function zeroAdjust(n) {
    var t = "0"+n;
    return t.substring(t.length-2,t.length);
}

// these also need leading zero if < 10
var arrIns  = [ "01","21","24","28","42","48",
                "12","23","34","36","37","46",
                "03","18","19","25","44","45"  ];

var allLucky = arrIns.toString();

var arrLot  = [];
var arr     = [];
var count   = 0;
var t;
for(var i=1; i<50; i++)
  {
    // force i to string then
    // compare i with all lucky numbers
    if (allLucky.indexOf(zeroAdjust(i)) == -1 ) {
      arr[count] = i; // add +"" 
      count++;
    }
  } // for-loop

document.write("length of arr[] ="+ count +"<br>");

I have provided this just to help you move forward (if my guess was correct)

here are some more bits of code for you to look at.
csv = comma,separated,values which is what you get with an array.toString() call. Smile | :)

JavaScript

//==========  EXAMPLE  ===============
// Save & Restore an array
var arrIns  = [ "01","21","24","28","42","48",
                "12","23","34","36","37","46",
                "03","18","19","25","44","45"  ];

var arr_to_csv   = arrIns.toString();
document.write(arr_to_csv);

var arr_from_csv = [];
var tmp = arr_to_csv.split(",");

for (var i=0; i < tmp.length; i++) {
    arr_from_csv[i] = parseInt( tmp[i]);
    document.write(arr_from_csv[i]);
}
//====================================

The following code has arrIns as a N-dimensional array (3x6) of numbers, but it would complicate the code for comparisons, like the allLucky string compare above.

JavaScript

//==========  EXAMPLE  ===============
// arrIns array of 3 x 6 (not "strings")
var arrIns  = [ [ 1,21,24,28,42,48],
                [12,23,34,36,37,46],
                [ 3,18,19,25,44,45]
              ];

document.write("lucky numbers, one week at a time<br>");
for (var week=1; week < 4; week++) {
  document.write("week no: "+ week +"<br>");

  for (var i=0; i < 6; i++) {
     document.write(arrIns[week-1][i]);
  }
}
//====================================

How can I submit form without the querystring

The easy way is to use the POST method instead of GET for your form.

Submit as a POST request such that data is sent in form headers. If you do a GET, you would have to use querystring.

IE(10) has problems with SELECT.onchange

captnmac8-Apr-13 7:22

I see that IE(10), after changing an OPTION's .text property from within the OnChange event handler, the SELECT element becomes unclickable (like disabled) for the user.

HTML fragment to reproduce the behavior:

JavaScript

<form><select size=3 id=sel>
	<option>one
	<option>two
	<option>three
</select>
<textarea name=debugga cols=40 rows=10>
</textarea></form>

<script>
	document.forms[0].sel.onchange=function ()
	{	var opt = this.options[this.selectedIndex];
		this.form.debugga.value += "[click:"+opt.text+"] ";
		opt.text += '#';

		//alert('now it works');
	}
</script>

When using onclick instead of onchange, the problem does not appear.
When opening an alert box after the .text change (uncomment line 'now it works'), the problem does not occur either.

Has anyone an idea how to do a workaround or if Microsoft has already commented on this bug? I cannot find a single article about this issue. Thanks in advance!

Personally, I'd try fixing the HTML and trying again. (You haven't closed any of the 3 <option> tags)

<form>
    <select size=3 id=sel>
        <option>one</option>
	<option>two</option>
	<option>three</option>
    </select>
    <textarea name=debugga cols=40 rows=10></textarea>
</form>

you should test if your suggestion works before giving such an trivial answer. no -- it doesn't make any difference, since the closing tag for the option element is optional by specification.

You're welcome. Smile | :)

Your title clearly indicates a problem with IE10 - you sound like you know a way of testing with it without having it? I'd be most interested.

I offered a suggestion and (wrongly) implied that the html was broken. Sorry you feel so aggrieved.

I assume you get the same result when using addEventListener to attach the handler?

how can save a file through javascript

Graham Breach11-Apr-13 2:56

Looks like a weird browser bug to me. I've had a play with your script and found an ugly workaround by blurring the select box in the onchange handler:

JavaScript

document.forms[0].sel.onchange = function() {
  var opt = this.options[this.selectedIndex];
  this.form.debugga.value += "[click:"+opt.text+"] ";
  opt.text += '#';
  this.blur();
}

Its urgent plz help..

Because of security reasons, file system is not accessible in JavaScript. You can try to write an ActiveX but will only be for IE.

In HTML5, there is a new API that can help but it has limitations like specific browser versions support.

Using a javascript timer in a asp User Control

I am currently converting asp pages to User Controls. In one of these pages a javascript timer displays the current time into a text block. Currently, the asp pages uses the javascript below. How do I move the timer javascript to a asp User Control and initialize it when the control loads?

<script type="text/javascript">

window.setInterval('timer();',1000);

function timer()
{
var d=new Date();
var t=d.toLocaleTimeString();
document.getElementById("TimerValue").innerHTML=t;
}

</script>

Thanks,

Hi. Also, when I run the code I get the following exception:

validating candian postal codes

I'm going crazy here. I've used this code for years and never had a problem. I tested a previous version of the the regex string for Canadian Postal Codes and it worked fine. But today doing a DHL Shipping upgrade testing on Canadian Addresses, I can't get my Canadian Postal Code Regex to produce a match.

So I'm trying K1A 0G9, K8N 5W6, LDU 9Z0
for example. I ran some test in RAD Regex Expresson tester, and could not produce a match as well using
/^[ABCEGHJKLMNPRSTVXY]{1}\d{1}[A-Z]{1} *\d{1}[A-Z]{1}\d{1}$/

Wait, I just tried this and got a match with the RAD Regex Expression tester, hmm
^[ABCEGHJKLMNPRSTVXY]\d[ABCEGHJKLMNPRSTVWXYZ] \d[ABCEGHJKLMNPRSTVWXYZ]\d$

This seems to work with every variation in the RAD tester, maybe this one
^[ABCEGHJKLMNPRSTVXYabceghjklmnprstvxy]{1}\d{1}[A-Za-z]{1} *\d{1}[A-Za-z]{1}\d{1}$

Wish a real Canadian would enlighten me on this one.

I must admit the canadian postal code system is pretty slick, but not sure why I have so much trouble with it.

var match_b_PostalCode;
var re_Shipping_PostalCode_CA = new RegExp("^[ABCEGHJKLMNPRSTVXY]\\d[ABCEGHJKLMNPRSTVWXYZ]( )?\\d[ABCEGHJKLMNPRSTVWXYZ]\\d$/i");
var re_Shipping_PostalCode_MX = new RegExp("^\\d{5}(-\\d{4})?$");
var re_Shipping_PostalCode_US = new RegExp("^\\d{5}(-\\d{4})?$");
var txt_Shipping_PostalCode = $('[id*="_txt_Modal_ShipRate_AddressInput_PostalCode_Field"]').val().toUpperCase().trim();
            
   switch (countryCode_Value) {
      case "CA":
         match_b_PostalCode = re_Shipping_PostalCode_CA.exec(txt_Shipping_PostalCode);
      case "MX":
         match_b_PostalCode = re_Shipping_PostalCode_MX.exec(txt_Shipping_PostalCode);
      case "US":
         match_b_PostalCode = re_Shipping_PostalCode_US.exec(txt_Shipping_PostalCode);
   }

Am not sure what I’ve done wrong. The below code is supposed to show the time and date as Time|Date: 16:08:24 31/3/2013, however its now showing up as Time|Date: 16:08:24 0/3/2013…

JavaScript

<script>
function startTime()
{
var today=new Date();
var d=today.getDay();  //---Day Sunday
var dt=today.getDate();  //---Date 1-31
var mt=today.getMonth() + 1;  //---Month
var y=today.getFullYear();//---Year
var h=today.getHours();  //---Hours
var m=today.getMinutes(); //---Mintutes
var s=today.getSeconds(); //---Seconds
// add a zero in front of numbers<10
m=checkTime(m);
s=checkTime(s);
document.getElementById('txt').innerHTML= "Time|Date:"+" "+h+":"+m+":"+s+ " " + d+"/"+mt+"/"+y;
t=setTimeout(function(){startTime()},500);
}

function checkTime(i)
{
if (i<10)
  {
  i="0" + i;
  }
return i;
}
</script>

Note: Everything else is fine except for the date, what with it bring up '0' instead of '31'
