I'm having a little bit of a problem with some ajax on my page.Below is the code in it's current state (with debugging info included):
Code:
function setrating(id)
{
[code]....
I have several functions with code along the lines of:
var xmlDoc = requestXML("ajax.asp?SP=SelectRelatedTags&tag=" +
array[i]);
The requestXML() function includes the code:
var xmlDoc = null;
http_request.onreadystatechange = function() {
if (http_request.readyState == 4) {
if (http_request.status == 200) {
xmlDoc = http_request.responseXML;
} else {
alert('There was a problem with the request.' +
http_request.status);
}}};
http_request.open('GET', url, true);
http_request.send(null);
return xmlDoc;
However, the last line (the return) executes before the readyState
reaches 4. How do I return the xmlDoc to the functions only once the
xmlDoc has been assigned? I tried putting the return statement in a
while loop with the condition that the readyState must = 4 - this
worked, but makes the browser popup a message saying the script is
slowing down the system.
If it is possible to pass a php variable through to a javascript function.
Example.
I have a bit more to the code but that is the bare essentials as an example. If i remove the $id and $name from the passTest() for onClick the function works properly. However if I leave them in the function doesn't seem to work at all.
I have these 2 functions... The first draws a graph, then second I am trying to use to generate the "layout.addDataset" line of code, which it does perfectly. However, I am unsure how to call the function generatedataset from within drawGraph, and pass the variable "mainstring" as it is not set as a variable. code...

I am trying to pass a php variable to a javascript function using a link but it doesnt get through.
Code:
I have a javascript will a) look for a certain value in a drop down box and b) depending on what value is selected open up a div that includes link that when moused over will pop up with an alert box contain the passed parameter. A couple problems with this, one is I am not as sharp on Javascript as I am on PHP, and two, when I manually place a value into the function parameter, if it's a number it works fine, but if its a string or word, it comes up with an undefined error. why the undefined error is coming up only on strings or words?

Can I know how to pass a variable from one function to another using parameter.
The above code seem not working.
Let's say I have this function: function add(x, y) { var add = x + y;
[Code]...
So let's say the value of select_first is "1", and value of select_second is also "1". But when they are passed to the add function, the returned value is 11 and not 2. So what I understood is that it took the values as strings instead of integers. What should I do so that select_first and select_second are integers instead of string?
I have a bit of php that creates an entry on a page for each row in a table, some pages may have multiple entries, others just one.
eg.
<h2 class="title">{title}</h2>
{summary}
<p onclick="openBox({entry_id})">Click to read more ></p>
<div id="{entry_id}" style="display:hidden;">{body}</div>
I would like to have just one function to open and close all individually, eg.
$(document).ready(function(){
function openBox(id){
if ($("#id:first").is(":hidden")) {
[Code].....
Well I know I'm doing something wrong as this is not working, and I don't know how better to explain I hope this is sufficient, I'm not worrried about the php/html bit as that is working fine.
I'm working with the following code:
parent window:
Code:
<html>
<head>[code]....
Currently, the Code will open the child window, show a search box, search for the database and display links, when you click on the link, the parent window will show the variable passed. My question is, how would i change this so that each of the variables displayed would have a php variable that i could submit with a form?
Pass variable to jQuery function in another page? I have what I think is a simple question but I can't find an answer. I have two html pages - one.html, two html. [URL] one.html contains a jquery function that alerts the variable it is passed.
[Code]...
The problem is I want to call and pass the variable from another html page - two.html How can I call and pass a variable to the jQuery function in one.html from two.html ?
Might be a simple question, but I'm a Javascript and OOP newbie.
I have a form that I'm using Java & Ajax to dynamically validate while the user is typing (sort of, it actually executes the validate script after a 1 second pause in typing has passed). code...
<code>
<script type="text/javascript">
function interval_setting(){
var clear = 0;
clear =setInterval("xmlhttpPost11('index.cgi','tracker_shower','Latest_frame','Tracker_loader',clear,'','','')",20000);}
</script>
</code>
cant i pass variable clear like this ? Cause in xmlhttpPost if i give single quote to that variable it gives 'clear' not 0;
How do I pass a PHP variable into a window.onload event function? I have a URL that I need to pass to the JavaScript file that has this function in it. The JavaScript file itself is being linked from the PHP file that will pass the variable and I've seen many examples of how this is done via embedded JavaScript, but none where someone is linking to an external JavaScript file. I suppose this is probably a trivial matter to most of you, but I've never done this before and could use some guidance!

I am using ajax to pass php variable to javasccript function as shown below for my particular application.
i am using the foolowing function from ajax.js freely available from net to implement the ajax functionality as
var abc = new sack();
PHP portion which passes the response text:
************************************
<?
$table=$_GET['tablename'];
[Code]....
1] When $table is having a string with only numeric characters for eg: "123" we get the alert
2] When $table is having a string with alphanumeric characters for eg: "123efg" we get the error report as "missing ) after argument list"
3] When $table is having a string with alphanumeric characters for eg: "efg123" or "abcdfr" we get the error report as "efg123 is not defined" or "abcdfr is not defined".
i want to update my database record using AJAX. but i am stucked where pass my row value(array) into the ajax function. for the button save, i think its working because if i put it in while loop of my fetching record function its updating my last record.

I have a php page which returns a table representing a query sent to a MySQL database. So far it has worked in every case except now that I'm trying to use it to call a stored procedure, in which case the readystate is staying at 1 and never completing.
I have logged the results of the php file both in an error log and looked at the response from the request using firebug, both of which show a correct result.
Why isn't this returning properly?
Here are the relevant javascript functions:
Code:
function customizeType()
{
$("custom-header").innerHTML = "";
$("custom-top").innerHTML = "";
[Code]....
After the page loads, the error log shows correct results for all queries.
I have been trying to figure this out for a few days now and have finally come to the point where I think I got it but may just need a little push to get what I want.
Heres the situation:
I have this function that uses ajax to access a database and returns the results in the responseText. That part is working fine, I have confirmed that the responseText contains the information that I need
**************code*****************************************
//new ajax already created and assigned to the variable xmlhttp//
var response_recieved = "some data";
function get_answer(Table_Name, Field_Name, Data_Type) {
[Code]....
As evidence by my posting, this is not working correctly. The variable response_recieved is coming up undefined outside of the callback function assigned to the onreadystatechangeproperty.
Based on the information that I have gathered online from various forums, I believe this issue has to deal with a problem with closure in the callback function assigned to onreadystatechange property. I don't think it has any. Based on the fact that there is no anonymous function in that function. But my problem is that the call back function is anonymous itself... I think???
get the variable response_recieved to survive outside of this function.
Theres nothgin wrong with my ajax, it works and is sending other variables but whe i want to send "pood" from
function farmers(pood, happy)

I am writing a Javascript to sort and write out some stuff. PHP is not an option so I need to get this script working.
The problem arises when I want to make a link to the next page. (i.e. Like the link in google for the next 10 results)
I have <a href=# onclick=FUNCTION(VALUES)> written dynamically by the script.
It is written onto the document correctly, but the problem is, when the link is clicked, some seemingly random values are passed to the function.
I also have an invalid character error that arises when I pass the "whereVARquoted" variable into my function (code 2) which disappears when the variable is removed (code 1).
My code is below:
Code 1:
<script>
Code 2:
<script>
I want to assign value to global variable in javascript from jquery ajax function.
Here i need the value of trueFalse from success function.
I'm trying to fetch JSON contents via ajax() from a file using this code:
// grab pages via AJAX request
sm.pages = (function() {
var json = null;
$.ajax({
async: false,
global: false,
url: 'pages.json',
dataType: 'json',
success: function(data){
json = data;
console.log(data);
}});
return json;
})();
One problem though. The success function doesn't seem to be firing at all even though I can see the request was successfully in Firebug.
