i'm new to ajax. simple request no problem - but it seems when I set
the response handler function, I can only pass the function name and
not give parameters, so I have a problem when starting e.g. 5 ajax
requests parallele. how to do that correctly? for one case, where I
used *different* resp. handlers, I solved the problem by global
variables - but now I have a loop of e.g. 20 calls to the *same*
r.handler and I don*t know how to tell the function *which* request of
the 20 to use. I expect the solution to be simple but how..
I have added an event listener to a LI item in the DOM:
liNode.addEventListener("mouseover", mouseOn, true); The mouseOn function: function mouseOn(e) { // Test for IE or Firefox var e = (!e)?window.event:e; var yPos;
[Code]...
I would like to pass in another parameter to the mouseOn function in addition to the event that is passed in automatically. Is there a way to do this?
I have an ajax post which returns a large html response. It is getting truncated at 98784 characters everytime. Is there a limit to a response size or a way around this?
I'm having a problem with the returning a php variable from my ajax php handler.
I call the handler...
if(ajaxRequest.readyState == 4 || ajaxRequest.readyState == 0){ var ajaxDisplay = document.getElementById('ajaxDiv'); var refreshID = ""; var timeout = "<?=$timeout?>";
ajaxDisplay.innerHTML = ajaxRequest.responseText; //Change Refresh Timeout Based on Remaining Song Length refreshID = setTimeout("DoRefresh()", timeout);
DoRefresh() function is the ajax function. What am I doing wrong?
I'm trying to bind an event handler to a button in a page loaded via Ajax. This procedure should apply to every page I have to load via Ajax. I have tried two things: first, I declared the 'click' event handler for the button like this, and just did my ajax request. Here's the code:
$("#close_button").click(function(){ alert("This should popup"); }); $.ajax({ url: 'js/ajax/text.html',
Some servers return JavaScript as the response to an AJAX request. When the response JavaScript is eval'ed it calls other JavaScript functions already in the browser to update elements, etc. This seems like a good system because it allows so much freedom in creating the desired behavior in the browser. The required data doesn't have to be converted to XML or JSON on the server. The browser doesn't have to have templates for interpreting and converting this data into some change in the browser. All of the conversion algorithms don't have to be written and changed when new behavior is required. This remote procedure call approach is the predominant system in the Ruby on Rails world. (Unfortunately they are calling Prototype.js functions.)
However apparently some people seem to think this remote procedure call approach is a bad idea. I can't see why it is so bad because it is so lightweight and flexible. It also helps to keep the client less intellegent which seems good in a world of incompatible client-side bugs.
If I use some neutral data format like XML to accomdate different types of clients then I have to write different client-side interpreters for each type of client (browser, RSS, POP, cell phone, etc). Why not just write different server-side code that generates the correct JavaScript (or other) for the requesting client type?
I am using ajax / php where I am looking up some info from the database and populating a select list dynamically, however I am running into some sort of size limitation with the ajax.response object. If the string I am passing to javascript from php is too large javascript does not get it all the data. The magic number appears to be 6123 characters, anything below that it works fine, anything above and if I alert the ajax.response, I see the string is cutoff. Any ideas where this limitation is defined?
Now what i want to do is: i have a callajax() function. with in this function i will call do_login() function. this do_login() handles an ajaxrequest and returns the responsetext.
Now i want to do some validation on this responsetext(in case of onsuccess). so i am trying to return value to callajax() function for onSuccess case in ajaxrequest.submit();
That is(onsuccess response) supposed to be some string( but not true or false). but i am always getting false in ajaxcall() function. i know the do_login() function is returning false before ajaxrequest completes
So i want to stop this and make do_login wait until ajaxrequest completes and then i want to return it's response to callajax() function.
I am wondering how possible it is to use eval() to parse javascrpt that is pulled in through ajax(innerHTML)? I have found a few notes about this, such as:
In my browser, I make an AJAX request. The server sends me a fragment of an HTML document. That fragment has some JavaScript inside some script tags. How do I run these scripts when the fragment arrives at the browser?
In both the cases I am getting an empty response instead of expected html response.If I just copy paste this adnwurl in browser, I do get a proper html response. Its not working with ajax call.
I'm using $.ajax for an ajax request and I've setup a basic html form and if there are errors in the form when the user submits them my server side script is returning them in an array to the client with the errors.
If there are multiple values in the array, how do I display each error on its own line either using <li> tags or even just a <br/>? I'm injecting the ajax response into a div using .html() but how do I iterate the array within that div so I get one error message per line?
Do I need to construct the HTML on the client side after the ajax response has come back or should I do this on the server side before the data is even returned to the client? Right now I'm returning a raw array so that is why I'm asking the question about how to format things up and get the form errors into my div.
I have a simple ajax request that is supposed to (after a short timeout) redirect the page to the URL that the server sends back but it just wont work. It does work without the setTimeOut() function however.
var http = false; if(navigator.appName == "Microsoft Internet Explorer") { http = new ActiveXObject("Microsoft.XMLHTTP"); } else { http = new XMLHttpRequest(); }
function go() { var u = "http://site.com/"; http.open("GET", "go.php?" + "u=" + u, true); http.onreadystatechange=function() { if(http.readyState == 4) { var redirURL = http.responseText; setTimeout("window.location.href = redirURL;" , 2000); } } http.send(null); }
i have wriiten a form in my php page and i did call an ajax function on onsubmit, based on my ajax response my form have to be submit...but i am not getting ajax response text some times. But some times i got it correctly..i have used post method in my ajax function.
formid="reserve"; var f = document.getElementById(formid); var keyValue = ""; keyValue = buildKeyValueSearchFunction(f, keyValue); alert(keyValue); ajax_request = createRequestObject(); [Code]...
I am running the scripts below which should return a string containing a URL. So far, it cannot find the form contents in Firefox, but displays the non-dynamic data such as ?Location=. It won't work at all in IE.
HTML Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head>
I have an Ajax script which works fine in IE, Opera, etc, but not in FF 3.6. It appears the data sent is not recognized. My debug alert to display a simple variable sent is blank. In other browsers it displays fine. I'm developing on my PC so shouldn't have the cross domain issue, I don't think?
Here is the code function ajaxRequest() { $.ajax({ type: "POST", url: 'WTE_HTTP_Submit.cfm',
This could appear under Ajax, for example, you could have multiple objects that make a singular ajax call (say an RPC-like request) and you need to update the object that made the call during the callback with the result, but it doesn't have to be. The particular problem I'm thinking about happens to be ajax, particularly with multiple objects accessing the same ajax request (meaning I can't use a global or temporary variable).
One way that seems like it would work (just thinking about it in my head), is to create a hash, and to pass the key through the request, store the key in the response, and pick it up on the callback side. Then remove the item from the hash when done.
It only breaks when located inside the click handler. It does not return response headers or a response. Is there something about event handlers and ajax that I'm missing?
