You could find many of these answers in your course notes or, the documentation at http://www.w3schools.com/[^].
One of these days I'm going to think of a really clever signature.

Some of the correct answers are such bad practice, that I feel that by teaching you this rubbish that your teachers are inadvertnatly providing me job security.
Thanks

Hi everybody.
I need to aggregate the content of two different lists in one space, into one webpart in a different sharepoint, and this should be done via JavaScript.
I cannot use designer and the Data View Web Part, which would ease the situation a lot...
Do you know any example on the web, or something? I have been googleling a lot but can't find anything like this.
Thanks.

Hi when i login into my application when i click the browser back button the page is reloded for that one
Please give me the code in javascript
|
|
|
|
|
Please clarify what it is you want to happen. Is clicking the back button resulting in a page you don't want, or do you want to make the browser go back from javascript? Or do you want something else perhaps?
It might be better to try and describe what it is you want to happen.

i want if i click the browser back button the current page is reloded ..please help me that one using javascript
|

Why do you want to do this?
I'm not trying to be difficult - stopping the browser back button (which is what you are trying to do in effect) isn't 100% reliable, for example the client might have JavaScript disabled. What you are doing works against the browser's functionality and you are trying to stop a user doing what they want on their own machine. See http://forums.asp.net/t/989339.aspx[^] for a discussion and this[^] (which is quite old).
IMO it is more likely you should be handling this on the server and displaying something appropriate, even if it is just a message saying you can't go back.

Your question is not clear. Generally, on using browser back button page is reloaded from cache. If you want to handle this behaviour, following tip would help: Browser back button issue after logout[^]

history Object Internet Explorer
---------------------------------
Contains information about the URLs visited by the client.
Attributes/Properties
Show:
Attributes/Properties
Methods
Method Description
back Loads a previous URL from the History list.
forward Loads the next URL from the History list.
go Loads a URL from the History list.
Property Description
length Retrieves the number of elements in the History list.
For security reasons, the history object does not expose the actual URLs in the browser history. It does allow navigation through the browser history by exposing the back, forward, and go methods. A particular document in the browser history can be identified as an index relative to the current page. For example, specifying -1 as a parameter for the go method is the equivalent of clicking the Back button.
back Method Internet Development Index
--------------------------------------------------------------------------------
Loads a previous URL from the History list.
Syntax
history.back( [iDistance])
Parameters
iDistance Optional. Integer that specifies the number of URLs to go back. If no value is provided, the previous URL is loaded.
Return Value
No return value.
Remarks
This method performs the same action as a user clicking the Back button in the browser.
The back method works the same as history.go(-1).
An error does not occur if the user tries to go beyond the beginning of the history. Instead, the user remains at the current page.
Standards Information
There is no public standard that applies to this method.
forward Method Internet Development Index
--------------------------------------------------------------------------------
Loads the next URL from the History list.
Syntax
history.forward()
Return Value
No return value.
Remarks
This method performs the same action as when a user clicks the Forward button in the browser. Calling the forward method works the same as calling the go method with a parameter of 1. An error does not occur if the user tries to go beyond the end of the history. Instead, the user remains at the current page.
go Method Internet Development Index
--------------------------------------------------------------------------------
Loads a URL from the History list.
Syntax
history.go(vLocation)
Parameters
vLocation Required. Variant that specifies an integer or a string. An integer indicates the relative position of a URL in the History list. A string indicates an exact URL in the History list.
Return Value
No return value.
Remarks
An error does not occur if the user tries to go beyond the beginning or end of the history. Instead, the user remains at the current page

function SetStateForNtimes(n) {
var popState = "?tabid=" + querySt("tabid");
for (i = 0; i <= n; i++) {
History.pushState({ state: 2, rand: Math.random() }, "RailEurope", popState);
}
}
function querySt(ji) {
hu = window.location.search.substring(1);
gy = hu.split("&");
for (i = 0; i < gy.length; i++) {
ft = gy[i].split("=");
if (ft[0] == ji) {
return ft[1];
}
}
}
Click here for more detail (History.js)
I have used somthing like above. It works like facebook has implemented.
Called this on ready state.
window.setTimeout("SetStateForNtimes(20)",2000);
Hope It will help.
Thank You,

Based on the forum picked, it looks like you are looking for a image slider or viewer that shows images randomly. If so, (even if not), the logic is to have a set of images and number them. Pick random number within the range 0 to total image count. Based on the number show that image. You can have a trigger of button or a timer to pick random numbers at intervals when needed.

Hi,
I want to generate random numbers in js from specific set of numbers iteratively e.g:
generate random numbers from array of (2,3,4) excluding 1 and next time from (1,3,4) excluding 2 like that. I have used Math.floor and Math.random()but they generate the numbers from given range like(1 to 4). What if i want to exclude any number or want to generate number from given specific set of numbers??

What's the problem with generating random number within a range, see if the random number is not the one you want and then re-get the random number in case it's the one you wanted to avoid?
Example;
Random number between 1 to 4.
You wanted one of (1,3,4)
If random number returned is 2, ignore and re-get it.
Define a method that takes range start, end and exclude number:
function getRandom(rangeStart, rangeEnd, excludeNo)
{
var ranNo = GetRandom(rangeStart, rangeEnd);
if(ranNo == excludeNo)
getRandom(rangeStart, rangeEnd, excludeNo);
return ranNo;
}

Using your example, I would generate a random number between 0 and 2. Then use the result as an index to your three element array.
|
|
|
|

If you need to use this often for arrays, I would add a function to the array prototype:
Array.prototype.randomPick = function(){
var M = this.length-1;
var N = 0;
var randomIndex = Math.floor(Math.random()*(1+M-N))+N;
return this[randomIndex];
};
Then you can call it:
var arr = [2,3,4,5,4,6,8,9,7];
alert(arr.randomPick());
