JQuery :: $ Function Not Available After HTTP POST
Sep 21, 2011
I have an HTML div that gets filled with the following HTML/javascript code via ajax:
<script
type
=
"text/javascript"
[Code]....
The idea is that when I post the form the response gets loaded back into the same div. This works, but when I use the form to post a file I see the following output from Firebug: $ is not defined
Naturally when I resubmit my form again (for example after incorrect input) the resulting response doesn't get loaded into the div because jquery never setup the ajaxForm method.
I am developing an ASP.NET web application that requires the use of remote calls going on behind the client's page in the browser. I successfully got the service working via SOAP (I have to use SOAP due to the fact that I need this to be compatible with Netscape 7.0). However, there is a memory leak in Netscape using SOAP calls, and I can't figure out why. So I thought that accessing the web service with HTTP-POST or some other javascript method might alleviate this problem. Can anyone show me another method, or tell me what is wrong with my SOAP calls?
Prior to posting a form (.asp page) to a URL, I check the parameters being passed and they are not encoded, but when the URL is served it is encoded. How can I prevent this?
Is it possble to do a HTTP post request inside JavaScript? - That is I don't want to use a HTML FORM, but need a JavaScript to post a value to a PHP script not encoding the parameters in a URL.
I am trying integrate an upload system from YouSendIt.com in to my companies forms. The code they give for integration is basically an iframe with a coded URL set for the source. Their server sends a postback using HTTP Post method but I am not sure how to access the data that is sent back. I do not need to display it but I need to use it for validation purposes in the rest of my form. The Iframe code is as such:
I am using jquery.ajax() to make a POST call to web server which returns HTTP 201 response for successful creation of object at server. Since 201 is a success I expect the success function specified with jquery.ajax to execute but instead it executes the error function specified with jquery.ajax. Here is how I am using jquery.ajax call.
i've got a function which makes a call to the database( via jquery $.post) to check if a username already exists. All the data I get back is fine and both the conditional statment works as intentded. I just can't get the function to return a value to the other function that calls it. Could this be something to do with the scope.
I know that there can be a 3rd argument for Jquery's $post. I want to figure out what the best solution is, for a function, that can be used so we can guarantee that no other jquery functions run until the $post action is completed. I use $post to hit 'vote.php' to submit a vote but I want it to complete this process, and be able to confirm it (Without an annoying alert) so it can properly continue with the process of displaying vote results to the site visitor. I just am not sure what I should do. What is the best idea, just create a function that displays a 'please wait' image that loads for a few seconds and then continue?
The post is submitted and returns correctly (confirmed by firebug lite), however the code inside the nested function fails to execute on both IE6 and IE7. Works fine on IE8, everything else. $ ( "form.add" ). submit ( function () { //code outside of .post function executes successfully $ .post .....
I am new to all this but making good progress and having fun in the process. I have written quite a bit over recent weeks (including a few $.post / $.ajax calls) for various sites/applications but this one is really puzzling me. Here is a snippet of code that is causing me problems.
[Code]....
The problem is that execution jumps from line 2 to line 6 ... ignoring the function(data) and I am not sure why. I get the correct value of "team" arriving at the perl script .... and the perl writes the correct json back. I just can't think where else I need to look to debug this - as I said, I have done something similar 5-6 times over the last few weeks - all without a problem. So I am sure I am doing something stupid here.
I can't seem to get a variable declared from within a post callback, so that I could manipulate my script accordingly. I have delete.php, that deletes an id from a mysql db. If it fails, I want the script to stop and display the error. The .php script echos an "ok" if everything went fine, if not - it echos the error.var abort_error; // set the error variable
I can't use the value returned by $.post() method out of the scope of success function.
For instance in below example myvar alerted as empty even though var is alerted with a value. Besides, hide does not work in the scope of success function.
I try to create form to subscript a newsletter using plugins and the $.post() function ,but the URL outside the server[URL] to send me an email if it receives the data but it doesn't work,
here is the code <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1" />
I can get it works if I using <form> tag with an action="post" and a submit button to post to another php page by using this statement to get all controls in receiver's page _GET['mycheckbox'];I have tried
I just started using jQuery, but i can't get it working. On the index.php page I want a search form, that post's to search.php. Following next, I want that the html of search.php (which will only be a table with the results), is show into the 'results' div in the index.php.
This is the code im using:
<script type="text/javascript"> /* attach a submit handler to the form */ $(document).ready(function(){ alert("Ok - 1");
[Code].....
The alert's are for debugging, but none of them show's up.
I have been struggling with a form wizard all day. I'm using jquery stepy (form wizard) along with validation plugin. To cut a long story short, my first step is to get MySQL connection from form controls details. On submit ('next' button) a check is made on an empty hidden control ('hid').
So, if the function checkDBData passes, false should be returned, so that the form can progress to the next step. If the connection details fail, true is returned so that an error msg is posted.
Here's the checkDBData function: function checkDBData(){ var host = $('#mysql_host').val(); var username = $('#username').val(); var password = $('#password').val(); var dbname = $('#dbname').val();
The return values don't find their way back to the rules. However, if I hard code false and true to the function... function checkDBData(){ var host = $('#mysql_host').val(); var username = $('#username').val(); var password = $('#password').val(); var dbname = $('#dbname').val();
$.post("install/sqlcheck.php", {"host": host,"username": username, "password": password, "dbname": dbname}, function(msg){ if(msg.required == false){ return false; }else{ return true; }}, "json" ); return false; //or return true for testing purposes } This works. I assume it's due to the asynchronous nature of the ajax call.
I am new to Javascript and i'm currently building a site that entails a 'quiz' part where the client selects an option from a radio button. Then they move on to a different page, and so on and so on until a results page where the correct number of questions answered are made into a percentage.I understand that you can use the GET or POST to pass this into the query string and then extract the answers from the query string but I am having trouble implementing this.
I have a simple echo "text"; in my php function. No matter what I do, jquery's response returns a "-1". I couldn't find anything on the documentation about returning a -1. What sort of error happens if response is returning a "-1".
is there a way to find all http://* and cover it by link ? I have a text like [URL]..I spent hours searching whole internet and did not find an solution.
