I'd like to have basically rotating images on my page but I'd like to pull them from a database. how to set an image rotation like every 10 seconds but have it call a function which will use AJAX to be able to pull the images from the database?
View 3 RepliesI have a script that runs when the page is loaded, but I'd like it stop running after a specific time interval.
I think I need to use this:
var t=setTimeout("javascript statement",milliseconds);
I understand the milliseconds, that's the time delay. What I don't get is what do I put inside the "javascript statement" to kill that specific script?[code]...
I want to have a random change of the border and text color of certain DIVs (with a certian class) after a specific time interval. I managed to get a random color change after the time interval, but I'd like to just have a set of colors, which the random generator can choose from. So here's my code:
Code:
<script type="text/javascript">
$(document).ready(function(){
var intervalId = setInterval(function() {
int i = (int)(Math.random() * 4);
[Code].....
So "i" can be a number from 0 to 3 and depending on this number, the variable "col" is a specific colorvalue which the border and text color will animate to. That was my thought, but something about the random color generator doesn't work
I would like to achieve the background color change effect by using jQuery like the one in www.intigus.com. But do not know how to do that.

I am using jquery for getting ajax responses from server side functions.
I am in a situation where I need to make two ajax calls one after another and the second one is dependent on the response of the first one.
I have tried to use a code which is similar to this one?
$.ajax({
type: 'GET',
url: 'myURL',
success: function(data)

Is it possible to get two have two ajax calls , one dependent on the other?
I have made a page thats makes an AJAX call to the server gets the time and displays it. In the OPEN method i have set
req.open("GET","/timerProg.cgi?param1="+new date(),false);
I have set the last parameter as false as i am expecting a synchronous request so that time displayed should be consistent.
I am using new date() since the browser is caching my request and displaying the same output everytime as i dont know any other alternative.
The alternative so that browser does not cache the results and gives proper output each time.
I have a web page a lot of thumbnail images arranged in a table. I would like the user to be able to click on the thumbnail to open a window with a larger view of the image.
So I wrote a JS function to accept a URL as the argument and open a new pop-up window with the given parameters. I need this function to potentially run multiple times from multiple links (in this case images) on the same page. However, after the first time I click the link, the function runs, and I close the pop-up, the function will not run again if I click the same or another link on the page. If I refresh the page, the function will work once and then not again. Is there a buffer I need to clear or something to reset to allow multiple links to work?
I have tried the function call in a whole slew of ways. Here's my current code (I "..."'ed out the URLs for brevity):
<script type="text/javascript">
function zoomWindow(url)
{
zoomWindow=window.open(url,"", "toolbar=no, location=no, directories=no, status=no, menubar=no, scrollbars=yes, resizable=no, copyhistory=no, height=645px, width=550px");

In my js application, consecutive ajax calls are made while running in a for loop. I am using prototype.js for AJAX calls. now if I don't call any function on onComplete event then everything is ok. but if I do so, then the function I have set in an onComplete event is invoked once or twice. rest of the time it doesn't work. the code is like the follwing:
/**
* Moves selected options from source to destination select list.
* @param source select list, destination select list
* @return none
*/
function moveMultipleOption(sourceListId, destListId)// single or multiple based on selection
{
var sourceListBox = document.getElementById(sourceListId);
var destListBox = document.getElementById(destListId);
var sourceTableName ;
var destTableName;
if(sourceListId == 'firstList')
{
sourceTableName = "left_table";
destTableName = "right_table";
}
if(sourceListId == 'secondList')
{
sourceTableName = "right_table";
destTableName = "left_table";
}
for(i = sourceListBox.options.length-1; i>=0; i--)
{
//for() loop is used for finding how many options are selected.
if(sourceListBox.options[i].selected)
{
addOption(destListBox, sourceListBox.options[i].text, sourceListBox.options[i].value);
sourceListBox.options[i].selected = false;
AjaxRequest(sourceListBox.options[i].value,sourceListBox.options[i].text,sourceTableName,destTableName);
}
}
}
/**
* Calls to server through Ajax
* @param option value, option text, source table name and destination table name.
* @return none
*/
function AjaxRequest(i,textValue,sourceTableName,destTableName)
{
var url = '/run.php/SelectList'
var pars = 'cmd=singleTransfer' + '&itemValue=' + i + '&textValue=' + textValue + '&sourceTableName=' + sourceTableName + '&destTableName=' + destTableName;
var myAjax = new Ajax.Request(
url,
{
method: 'get',
parameters: pars,
onComplete: showResponse
}
);
}
function showResponse(originalRequest)
{
// CODE IN THIS FUNCTION DOES NOT ALWAYS EXECUTE.
}
Now i have solved the problem for the time being by making a single call to ajax for the whole loop. Now my question is : what is causing this problem? Can I give time delays between two consecutive requests?
is it possible to refresh/reload a page or div block in a time interval using jquery function? Without using Ajax or any other server side coding.

View 2 Replies View RelatedI have an image rotator that uses nested intervals. The outer one switches the images, and the inner one preforms the fade. The problem is is that the display is not updated during the interval function, and so, the fade is not displayed; the new image just appears- no fade.

I already have a PHP function (in a class) that retrieves the provinces/states from the database based on the country. I was wondering if it was possible to call this function instead of having to make a new file (in this case FindProvinces.php) that calls the function.

I am getting hi(); is undefined.

So this comes down to finding away to fire the javascript function only after the JQuery function has finished updating the HTML property of the DIV tag. I'm having a similar problem with a .post() command, and I expect whatever the solution is to this problem can be used to resolve the other as well.
Clearly I am invoking this wrong.

At the moment I have a link in a div that targets an ASP page to remove an item from the database.
<a class="small" href="/products.asp?Action=RemoveProduct&ID=<%=(rsCartItems.Fields.Item("ID").Value)%>">remove</a>
What I could like to do is use JQuery .click and .ajaxmethods but the only thing I am unsure of is hot to get the ID of the a href tag containing the unique item ID that relates to the db record. Can I use this.id?

Trying to call the same Ajax function twice on initial load of the page, but only the second one executed. I try to load mainpage, and inside mainpage I try to use ajax to load content1.asp to div1 and content2.asp to div2.
Test scenario (based on the Situation below):
- Page loaded, 1st ajax function skipped, 2nd ajax function loaded
- Remarked 1st ajax function, then 2nd ajax function loaded
- Remarked 2nd ajax function, then 1st ajax function loaded
- Moved the 2nd ajax function to above 1st ajax function, the 2nd ajax function is skipped.
Conclusion:
- the 1st ajax function always skipped. But Why? How to ensure both ajax is called upon loading of the page?
Situation:
mainpage.asp
<div id="div1"></div>
<div id="div2"></div>
<script language="JavaScript1.2">
ajax('div1', 'GET', 'page1.asp');
ajax('div2', 'GET', 'page2.asp');
</script>
