Ajax :: Call Freezes Page / Solution For This?

Jul 22, 2009

I am writing up a page to collect user input, and then generate an excel file.
The generation of the excel file is slow (more than 30 sec), so I decide to separate the input stage and file creation stage.

What I do is, collect user input, save to mysql, and pass a url (to the page of excel file creation) to javascript. Javascript will be triggered by setTimeout and run ajax to call the url after 2-3 seconds. This is the page structure of how I do it code...

The problem is, when the ajax is called, I cannot navigate around the pages (in the iframe of index.php). There is no error, but seems to be "loading". I have tried to use the same browser window to access the same site on the server, and also other sites on the Internet, to make sure the server is not busy to respond or the network is fully occupied.

JQuery :: Ajax - Can't Get "loading Please Wait" To Turn Off And The Page Freezes

Jan 2, 2011

I have a select drop down that triggers a change event to update my database. I am new at programming, so hopefully I am overlooking something obvious. My Jquery code actually works as desired to update the database, but when I try to add a overlayed "loading, please wait" message to the user, I can't get it to turn off and the page freezes. debugging the javascript in Firebug, It seems this code returns a 404 status, so it makes sense to me that my overlay will not turn off, but seems strange that the code updates the database as desired. what is wrong with this code? How can I get the overlay to turn off?

Ajax :: Call Without Page Reload?

Oct 28, 2010

I have a ajax function implementation: when the user is on one site, the ajax call keeps checking the server every 5 seconds if there is a server url change. If there is, there will be a message displayed to direct the user to go to another site. when the user go to another site, the ajax keeps checking every 10 seconds, if there is condition met, the message will be displayed to direct user to go back to the previous site. Also, after the message is displayed, ajax call keeps checking if there is another condition met, if there is, the message will automatically disappear.

The use case is: when one server is down, the message will direct the user to another site. On another site, when the previous server is up, the user could be redirected to the previous site. When the message is displayed (when server is down), the user may not follow the link to do anything. He/she may simply leave the message on and go to lunch or something, when he/she comes back, the server may be already up and the message should be disappeared instead of keeping showing the message. Therefore, the message should be displayed or disappeared automatically based on the ajax call condition.

I implemented the ajax function and it did check and displayed message. However, it wont' display the message only right after the user login or the user does a "refresh" to the page. After the message is displayed, when another condition met, the message won't disappear until the page is refreshed. Then the ajax calls keep doing every 10 seconds. The ajax call seems fine since when I set a alert, I did see the popup message show up every 10 seconds (but only after I refreshed the page.) Now the problem is: the message can't be automatically displayed. It can only happen when there is new page load (refresh). How can I solve this problem. I'm thinking of putting "windows.location.reload;" to load the page right after the condition met. But kind of feel I don't need to do this.

AJAX :: Textarea Word Not Appearing In Url Through It / Solution For This?

Feb 4, 2009

I used AJAX in this link code...

You have to go open the navigation box on the top left (sorry I have to simplify this in the future!) and then click the third link Compare Two Bible Texts. Once you enter a word in the first textarea and select the book, chapter, and verse it doesn't record it in the textbox underneath the verse dropdown select.

Anything wrong with this AJAX code?code...

Ajax :: Call In Progress Page Elements All Lag

Jun 2, 2011

I have a web app that performs a lot of ongoing ajax requests to keep multiple elements all up to date as time goes by, so there are almost always ajax calls going on in the background - this is neccessary in this situation. Now for the problem (aka annoyance), when there's an ajax call in progress page elements all lag, e.g. If I hover over a:hover etc everything lags and if I disable the ajax calls and do the hovers they all respond immediately. Is there some kind of way I can stop my ajax calls from making the page feel so damn laggy?

Ajax :: First Function Call On Page Load Always Skipped

Oct 9, 2010

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>

ajax.js -
function ajax(strDivID, strMethod, strURL){
if (window.XMLHttpRequest)
{// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
}else
{// code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}xmlhttp.onreadystatechange=function(){
if (xmlhttp.readyState==4 && xmlhttp.status==200){
document.getElementById(strDivID).innerHTML=xmlhttp.responseText;
}}
xmlhttp.open(strMethod,strURL,true);
if (strMethod="POST"){
xmlhttp.setRequestHeader("Content-type","application/x-www-form-urlencoded");
}xmlhttp.send();
}

Ajax :: Form And Call Integration - Insert Page Which Inserts The Data Into The Table

Oct 6, 2010

I have a form which goes to my insert page which inserts the data into the table. Except I didn't want to do a redirect to another page so I thought I would do an Ajax call. Both pages work until I change it to an ajax call.

I am pretty certain that it is because I took out the <form action="insert.php"> because otherwise the page would redirect but if that is the case I don't know my way around it and if it isn't the problem I'm not sure what is.

But here is my code:

AJAX :: Auto-Refresh - Page Thats Makes An Call To The Server Gets The Time And Displays It

Mar 2, 2009

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.

Website Link Does Not Appear On Profile Page / Solution For This?

Feb 8, 2010

I was told that the javascript code to my website needs to be removed in order for my website to be linked to a company's webpage. But I cannot remove the code the company is referring to code...

Does the IT Department at the company's webpage need to add or remove language that will allow my website to link properly? The company is asking me to change my website link but I cannot do that. Is the company uploading my link incorrectly? The company said "The JavaScript for your website is interfering and will not allow us to link your profile to your website."

I am very new at this and do not know what to do.

AJAX :: Call Based On Results Of A Previous Call

Dec 14, 2010

The general framework is a simple user login function. The user name is selected and a password entered as usual. The function grabs the element values and passes them to a php page that queries the database. An AJAX call returns the password to the function and then I want the innerHTML to be a choice of two web pages, depending on success or failure of validation. There are existing AJAX functions available on the internet but they are overly complicated for what I think should be a simple, quick to load function.

Where I am stuck is that the standard procedure to make an AJAX call is the browser window event. How do you make the call from within the function? I have tried creating two new variables, "success" and "again" to replace xmlhttp, but still stumble on the event to assign a value. I left the blank password protection (if statement) with that variable to demonstrate what I mean.

I've put in my code below, which is in development and successfully alters the innerHTML text depending on user input but I can't figure out how to insert the relevant php page. I have '// out' the testing bits, but left them for info. (I have tried full 'scripting' as the innerHTML, but it's messy.)

IE Freezes When I Set The Height Of A Div

Sep 11, 2006

I was using a piece of javascript function that I found online(unfortunately, I lost the source of this function), which basically provides the screen size. I added a few more lines to use that function so that when the user change the window size, the content div resizes as well.(didn't want the user to scroll down or sideways). Everything works except when I resize the height, IE freezes. Here's the function I am using:

Code:

function resize()
{
var contentHolder = document.getElementById('content') ;

var availW ;
var availH ;

if(document.all)
{
availW = document.body.clientWidth;
availH = document.body.clientHeight;
}
else
{
availW = innerWidth;
availH = innerHeight;
}

contentHolder.style.width = availW - 35 + "px" ;
//contentHolder.style.height = availH - 250 + "px" ;

}

The last commented line works fine in firefox and opera, which is supposed to resize the div so that all the contents are within the browser window and the user doesn't have any scrollbar. But as I mentioned, it's not working in IE. IE resizes the width properly. Any idea why IE is having trouble resizing the height? Please let me know if you think there's a better way of doing this.

Ajax Call Not Working

But my ajax call is not working.

AJAX :: Checking DOM After Call?

Jul 31, 2010

I'm having a problem where a button no longer triggers an event after I changed it through an AJAX call.Problem is, once AJAX has updated the DIV, the contents in RAM is different from what I see when I check the page source (CTRL-U in FireFox/Chrome).What tools are there to display the current contents of the DOM? I generally prefer to use Chrome/Iron, but if there are better tools for Firefox, I'm also interested.
