Ajax :: Append A String To Response Before Receive It?
Aug 19, 2009
I'm having a problem with Windows Mobile 2003 and AJAX. I'm using Windows Mobile 2003 because it is the earliest version of Windows Mobile I'm willing to build support for.
Basically, in Windows Mobile 2003, AJAX doesn't work if your response is only one character.
So I want to know if I can append something to the response string so I don't receive an error?
I would hate to have to re-program all the thousands of lines of code I have just because Windows Mobile 2003 isn't working.
I've already tried doing:
xmlHttp.responseText += "0";
This doesn't work because IE will throw an error since I cannot do anything with "responseText" since IE does not think AJAX is done (even though status = 200, and readyState = 4) because the responseText is too short. I tried it with two characters instead of one, and it started working again, so I know this is the bug.
When responseText is only one character, the typeof(xmlHttp.responseText) is unknown, but when it's at least two characters, it will show the type as "String."
Trying to validate a name... If it's in the database, return "exists" if it isn't return "newOne". I get "exists" or "newOne" back in my success function and set a variable (var ifExists) with that text, but when I try to do something based on whether ifExists = "newOne" or "exists", it always goes into the first part of the function...
jQuery:
var sendMenuName = "menuname="+menuname; $.ajax({ type: "post", async: false,
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 have a web service that accepts application/json but returns HTML to place in a DIV. I am not having any luck configuring the .ajax call so that it both POSTs in a format accepted by the web service and does not attempt to validate the HTML response as JSON.
[Code]...
It would seem that I cannot have anything other than 'json' in the dataType, even though from the docs it appears that this only affects the interpretation of the response, changing it's value to 'html' causes the web service to reject the call. I've also tried a converter but perhaps I'm not using it properly. Is it possible to use jquery to post JSON and get back HTML? What configurations am I missing?
I can append a query string to a setTimeout?So i have this:PHP Code: setTimeout("location.href = 'http://www.natural-environment.com';",1500); and i want to do this:PHP Code:var Email ="foo"; setTimeout("location.href = 'http://www.natural-environment.com?Email=+Emai+';",1500);
I have a string array in a class file that contains 5 values, which I need to display on the jsp page. but when I send it to the javascript it prints [Ljava.lang.String;@104f8b8 .what do i do about it. I am a new to javascript. Is there a way to get my array data from the response object.
I have an URL like www.bla.com#myhashtag. Now I want to get the string "myhashtag" without the hash.So far I have thish which should give me "#myhashtag", right?
var hashextract = location.hash; var hashextract2 = '<h2>'+hashextract+'</h2>'; $j(hashextract2).appendTo("#hashtag");
But I am not getting anything. Am I doing something wrong here?
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.
