for the footer i have used the concept of sticky footer.
When i increased the height of textarea instead of creating a vertical scroll bar.. it increased and hid behind the footer and when i increased further the vertical scroll bar came when it met the end of the page.
Even when i used developer tools then then footer is shifted upwards
Can someone please help me out. The demo page is up and running.
the link is http://widgetdemo.webatu.com/

Use
{
height:auto;
}
on all parents of textarea.
And set
{
position:relative;
}
on footer.
This will cause content to stretch to textarea height.

This worked like charm.. 
Thanks.
I have one more doubt. There is some extra space underneath the footer. And i am not able to identify where to change..
It will be great if u can help me out with it.
Thanks a lot

if i ll give
{ position: relative;}
for footer then it wont stick to the bottom of the page.
Its working fine with position as absolute only and
{height: auto;} on all the parents of text area.

Hm... Can you update your demo? Then I'll into that.

i think i have already updated the demo.. I checked in the developer tool there is an extra div getting added to the DOM.
This i guess is because of the hosting problem.
I tried to delete the the node from the developer tool. And then the problem went off.

Hi.. Can anyone provide some working example of calling a java webservice method(simple helloworld method) from javascript.
|
|
|
|
|
|
There are a ton of examples but I would certainly recommend using jquery[^]
There are only 10 types of people in the world, those who understand binary and those who don't.
|
|
|
|
|
By using Json() method we can send data to webmethod from the javascript.

org.mozilla.javascript.EcmaError: ReferenceError: "ActiveXObject" is not defined
Friends have encountered this kind of problem, I use ie8, Internet options security Settings for this part set I set, no, can you tell me how to solve? Please specify, thank you!
|
|
|
|
|
Say what?
Simple. You have a website that uses an ActiveX object. When you view this on your computer it is okay, you use IE8.
When your friends try to view it using FF, they get a message that says ActiveXObject isn't defined.
You wanna know why?
Easy, only (that's only, only, only or ONLY) Mirosoft Internet Explorer supports them.
There are precisely 2 options in this case:
1) Avoid using an ActiveXObject.
2) Force your friends to use IE.
I'll leave it to you to decide which is the least unpalatable.. 
(99%+ of the rest of the world went with option 1 btw)

I got a problem with arrays in js and I'm starting to lose it.
Every iteration generates a different value.
However, it appears that it pushes the same value in the entire row; so the entire row has the same "random" value every time.
I want to have every 'x' to have a "random" value.
for (var x = 0; x <= 90; x++) {
var col = CustomRandom();
memBlock[x, 68] = Math.floor(col.next() * 255);
}
The "2D" Array is created with a recursive function I found on the web:
function createMemblock(length) {
var a = new Array(length || 0);
if (arguments.length > 1) {
var args = Array.prototype.slice(arguments, 1);
for (var i = 0; i < length; i++) {
a[i] = createMemblock.apply(this, args);
}
}
return a;
}
And here is the entire script, just in case:
window.requestAnimFrame = (function (callback) {
return window.requestAnimationFrame ||
window.webkitRequestAnimationFrame ||
window.mozRequestAnimationFrame ||
window.msRequestAnimationFrame ||
function (callback) {
window.setTimeout(callback, 1000 / 60);
};
})();
function createMemblock(length) {
var a = new Array(length || 0);
if (arguments.length > 1) {
var args = Array.prototype.slice(arguments, 1);
for (var i = 0; i < length; i++) {
a[i] = createMemblock.apply(this, args);
}
}
return a;
}
var CustomRandom = function (nseed) {
var seed, constant = Math.pow(2, 13) + 1, prime = 1987,
maximum = 1000;
if (nseed) {
seed = nseed;
}
if (seed == null) {
seed = (new Date()).getTime();
}
return {
next: function (min, max) {
seed *= constant;
seed += prime;
return min && max ? min + seed % maximum / maximum * (max - min) : seed % maximum / maximum;
}
}
}
function getColor(R, G, B) {
var s = "#";
if (R <= 15) {
s += "0";
}
s += R.toString(16);
if (G <= 15) {
s += "0";
}
s += G.toString(15);
if (B <= 15) {
s += "0";
}
s += B.toString(15);
return s;
}
function animate() {
var canvas = document.getElementById("canvas");
var context = canvas.getContext("2d");
for (var y = 0; y <= 67; y++) {
for (var x = 1; x <= 89; x++) {
memBlock[x, y] = (memBlock[x - 1, y + 1] + memBlock[x + 1, y + 1]) / 2;
}
}
for (var x = 0; x <= 90; x++) {
var col = CustomRandom();
memBlock[x, 68] = Math.floor(col.next() * 255);
}
for (var y = 0; y <= 68; y++) {
for (var x = 0; x <= 90; x++) {
context.fillStyle = getColor(memBlock[x, y], 0, 0);
context.fillRect(x * 10, y * 10-10, 10, 10);
}
}
requestAnimFrame(function () {
animate();
});
}
function InitMemblock() {
for (var x = 0; x <= 90; x++) {
for (var y = 0; y <= 68; y++) {
memBlock[x, y] = 0;
}
}
}
window.onload = function () {
InitMemblock();
animate();
};
var memBlock = createMemblock(90, 68);
It's just an experiment with the canvas API; but If I can't control a 2D-block of memory I pretty much can't do anything.
If I can't get it to work I suppose I could use a single Array; but that would really suck.

It's not so tricky to create a 2d array, you just need to go about it a little differently to some other langs. First, you want to create the first dimension. Next, you need to fill each element in this dimension with a second array.
In my case, I've abstracted a screen. The first dimension is the rows, or y-coord. Each of these rows contains an array that holds all of the pixels in that line - the columns.
This code simply creates a 320x200 array and fills it with a simple xor pattern.
Of course, the other way to do it is to do what the compiler does - simply allocate a block of memory and then index into it yourself. The imageData object of the canvas does this - it has a 1d array that represents the pixels. So (y*width*4)+(x*4) will give you the index of the pixel you want. Since it's a 32bit pixel, there's 4 bytes for each one. It saves indexing and is much quicker and easy enough enough.
That said, here's the code I promised earlier.
var screenArray;
function mInit()
{
var x, y, width=320, height=200;
var result = new Array;
for (y=0; y<height; y++)
{
result[y] = new Array;
for (x=0; x<width; x++)
{
result[y][x] = x^y;
}
}
screenArray = result;
console.log(screenArray);
}

Hi all
i have this java script that with Firefox works fine but with IE9 don't work; any idea how to solve the problem ? Thanks in advance.
here the javascript
var element = e.srcElement || e.target;
if(element != null){
if(element.tagName == "INPUT") {
//alert("Before: " + element.getAttribute("type"));
element.setAttribute("type", "password");
//alert("After: " + element.getAttribute("type"));
}
}

hi,
I have reviewed yr code , can u check method compatibility with i9.
may be some problem in this code ..."var element = e.srcElement || e.target;"
|
|
|
|
|
you press F12 in IE9, or go to tools I think, and select developer for F12, and you can run it again, and it will flag the error for you.
What is e?, I don't see a reference to that object.

create an INPUT
IE 8
createElement('') // don't forget < and >
Opera, Mozilla ....
createElement('INPUT')
...
pointerOfInput.type=....
example onkey handler
function som(e) // e placeholder for event
{
var KeyCodeValue;
if( (e==null) || (e==undefined)){e=window.event;}
if('which' in e){KeyCodeValue=e.which;}
else{KeyCodeValue=e.keyCode;}
....
}
example mouseevent handler
function som(e) // e placeholder for event
{
if( (e==null) || (e==undefined)){e=window.event;}
var LeftPos=e.clientX;
var TopPos=e.clientY;
...
}

Chrome uses network path.
e.g. local document with iframe file:///F:/test/test.html
to test an document with iframe (IFRAME-tag) use a http server (not local).
may be chrome has an option to turn off this rule.
window.open("htmlfile","frameName") is not an iframe or frame
but what is the path of "htmlfile" ?
check path
iframe is an html document with small javascript interface to parent.
iframe is a single document with own rights (a frame with rights like a pure html document).
I use on ma websides only nested documents ---> IFRAMEs and parent pointer in javascript.
To overlay an document with other document use IFRAME, e.g. transparent background if IFRAME.
example for an IFRAME document
<doctype html="">
eval(parent.decode_javascript_of_iframe());
test(); // init of iframe AFTER decode above
This kind of using an iframe is like using of an "app". It is possilbe to create metro look
like win 8 in use of some iframes. Or iframes can us same place on parent document
(one iframe runs at a every moment).
IFRAME needs some ressources of browser ! Opera is fast. Chrome too. Mozilla is slow.
Only Opera can manage IFRAMEs fast.
On my webside www.twseiten.com you see iframe: See running mouse on top, put a mouseover this mouse
and IFRAME addons bar is visible (on off).
On this webside you find informations for apache http server in windows.
