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 have some pages being loaded via ajax and I want some of the elements hidden when the page is loaded.I could hide them with CSS and then change the css attribute when I want them to show but that just seems clunky to me since I'd have to assign <input style="visibility: hidden;"> to everything I wanted hidden on load. I know how to make it visible later when I need it.Using jquery's document.read doesn't seem like a good solution either since I'd have to make a list of everything I might want hidden right there on the main page.
I am learning JS and ajax.. successfully writing my own working scripts.. but, being a newbie, still hit the wall alot. Today's wall really has me stumped:
Developing locally, I am calling a page with a working XMLHttpRequest object.. and getting the response, fine. The problem is that the response is coming back with some space chars tacked on. There are like 10-12 space chars prefixed, and one space char suffixed to my response text. Even if I just stick in a single "a" char in the (now static) page that I call, it still returns
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?
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 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 a bbcode for download links on my forum when this bbcode is parsed, it will display a link under the download link BUT only for the first 3 links.so basically i would need a javascript with a counter, that will display some text if the counter is > 3 and then add +1 to the counter normally i would EASILY do this with php, but i can't (bbcodes are parsed not parsed by server on phpbb, and you can't use php code in bbcodes)
I have a form with a jquery listener that runs when you click the submit button. If there are errors an alert box will pop up telling you what they are. sometimes this box will pop up multiple times because the form is being re-submitted without clicking the submit button.
We have the following situation - when Ajax request is sent what's being returned by the server is usually an XML (which is used for DOM updates) but sometimes it's HTML which is a whole new page that should replace an existing one. I.e when we issue an Ajax request we don't know what will be returned and analyze the response to act accordingly.
Now, the way to replace the current document with a new one used to be easy and portable for both browsers (we're only supporting IE6 and Firefox 1.5):
document.open(); document.write( head ); document.write( body ); document.close();
where "head" and "body" are two parts of the result HTML. We had to cut it to two (rather than going simply with document.write( NewHTML )) because of IE - our head section contains references to external JavaScript files (<script type="text/javascript" src="sth.js"></script>) and IE only loads them when document.write() call ends. So if body contains any script block (<script type="text/javascript".. </script>) using any of JS referenced by head - IE would fail with something like "Resource undefined" if we push the whole new HTMl in one go by using document.write( NewHTML ). But it worked perfectly fine in Firefox, meaning
did the job just fine. What's even more important - it also evaluated all JavaScripts correctly - both in external files referenced by the head and in the JS blocks embedded in the body.
Until Firefox 1.5.0.6/7 where things stopped working completely - our lovely and used-to-be portable code
document.open(); document.write( head ); document.write( body ); document.close();
caused Firefox to loose all CSS/JS and display an HTML only page (as if CSS/JS were disabled). Removing document.close(); improved the situation a bit by displaying the page with CSS this time but still - *no* JavaScript was evaluated (meaning, JavaScript blocks embedded in the document's body were not evaluated).
I took a different path from this point by pushing the new content to document's head and body "innerHTML". It worked but not for JS evaluation - I had to do that manually. To evaluate the JS referenced in the head section of the document - I've traversed the head's DOM tree while looking for the "script" nodes, then downloaded all of them one by one using a synchronous Ajax calls (don't laugh!) and eval()-ed the response. To evaluate JS blocks embedded in the body of the document - I've traversed the body's DOM tree while looking for the "script" nodes and eval()-ed them.
The problem is following: eval()-ing external JS files after downloading them with Ajax doesn't work in 100% of cases - some statements using Prototype functions fail to execute ("prototype.js" is one of external JS files referenced in the head). Anyway, I'm almost sure that what I'm doing is plain wrong, i.e it's sounds silly to download all JS files referenced in the head and eval() them !
So how do I fix it ? Simply put - how do I replce the content of the document to the completely new one received as a response to asynchronous Ajax call ? The new content conatins doctype, head, body - it's a completely new page. And all JS referenced in the head and embedded in the body should be evaluated as well.
I really wish
document.open(); document.write( head ); document.write( body ); document.close();
was working in Firefox as before. Is it simply a Firefox bug, should I submit it ? Btw, document.open.write.write.close() works just fine in IE6.
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..
What I'm doing is creating a div element dynamically when the user clicks on a point in the page. Once created I create a record in my database table the corresponds to this div element and save information such as the width,height, x coordinate, and y coordinate of the element. This is done via AJAX accessing my web service. The weird thing is, I get really fast responses 80% of the time but 20% of the time, its taking a lot longer. For example, I would get a response after 50-100ms and at times I would get it in 2 seconds What do you think is the source of this problem?
I would like to send my form data to a php file but not to get any response. I want to send an ID so that PHP can do MySQL search and generate a PDF file. Problem seems to be that PHP is responding something back to HTML and that is messing my code. So I just want to send the data and run the scripit in PHP so that nothing is returned back to HTML.
I have ajax request with a success function. The data I'm getting back are an entire <html> ..</html> page. Is there a way to retrieve from those data only a given DOM element by its id ?
I am using jQuery for ajax call and receives HTML as a response.
Response I am getting is
I would like to parse this response and fetch "1","Debopam" and "Poddar" from the response HTML. How to do this and is there any way to parse it using jQuery selector.
