Ajax :: Trying To Pass Value In PHP Script Via JS?
May 3, 2010
I have a script which already passes one variable from a php script to my js script but I am having trouble trying to pass another one.
Here is my php code
<?php
include("config.php");
$keyword = $_POST['data'];
$sql = "select prodName from ".$db_table." where ".$db_column." like '".$keyword."%' limit 0,10";
$result = mysql_query($sql) or die(mysql_error());
if(mysql_num_rows($result)){
echo '<ul class="list">';
while($row = mysql_fetch_array($result)) {
$prodCat = $row['category']; .....
And here is my original js code:
$(document).ready(function(){$(document).click(function(){$("#ajax_response").fadeOut('slow');});$("#keyword").focus();var offset=$("#keyword").offset();var width=$("#keyword").width()-2;$("#ajax_response").css("left",offset.left);$("#ajax_response").css("width",width);$("#keyword").keyup(function(event){var keyword=$("#keyword").val();if(keyword.length) .....
But this breaks the js code and it prevents it from running.

I have an ajax script that sends a request to a servlet for information to be inserted into a table cell. The servlet then handles the request and replies with something like this:(I took the liberty of removing all the out.println tags)
<script language='javascript' src='whiteWine.js'></script>
<table align='center' border='0'>
<tr>
[code].....
For some reason, however, all the scripts functions cannot be found on the page. If I attach the
<script language='javascript' src='whiteWine.js'></script> on the page then the functions work, but they are used as polymorphism and incorrect information is shown. (There are 3 different scripts with the same named functions, but different implementations).Is there a reason why ajax can't send across scripts?

I'm admittedly a novice when it comes to AJAX. I can get stuff to work, typically, but really have no idea what's going on. I copied the original code from another source.
Now, something a bit more complicated is coming up and I can't get it to work.
Here's the script I'm using to start; the one that I typically use that works fine code...

I'm using AJAX to, on the click of a button, run a PHP script that dynamically generates a new line of text, and passes that to the script.The PHP script, new_sentence.php, just echos out the sentence.This works fine.But what I would like to do is for the PHP script to dynamically change JavaScript variables.how to pass multiple variables from PHP to JS.I can, of course, pass one by having the PHP script echo anything, and then use JS to set the variable to the PHP output. But what if I wanted to set two or three JavaScript variables at once?Here's my code in the HTML page that contacts new_sentence.php:
Code:
function ajaxRefresh(){
var ajaxRefresh;
ajaxRequest = new XMLHttpRequest();[code].....
When I press the "Refresh" button on the HTML page, it runs the ajaxRefresh function, which calls new_sentence.php. Then, once it gets the response, it changes the text of the element named "div" to whatever text the new_sentence.php echos.I'd like to figure out how to get a couple of variables.I would imagine this is simple. how to set the variables in PHP and then how to retrieve them in JS.

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've recently begun using AJAX on my website and have ran into a problem.My webpage: catalogue.php contains a category variable named $cid which the page GETS in order to display products from the correct category. This works fine.I now want to implement a drop-down box to sort by price, name, newest etc...I have tested the AJAX out with a dropdown box for changing the category and it works fine, this is because it is only passing one variable which it gets via the javascript "this.value".
The sort by price box requires two variables to be passed .I can pass the "this.value" which tells the javascript function I want to sort by price/newest/etc but I cannot figure out how to pass the category variable ($cid) so that when the xmlhttp.open calls the url: getSort.php it passes both pieces of info.My javascript is:
Code:
function showSort(str)
{
var cat = <?php echo $cid ?>;[code].....

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ''..'' at line 1
This is the External.js

how do i pass values back to javascript from the server via ajax? I don't want to pass entire html. Is there any way to simply pass a JavaScript object or an array without stuff like xml and json? I could probably do an eval() on the result to convert it to a javascript understandable array, but maybe there's a more clever way to do that?

I'm making this ajax call:
Code:
url = "/GeoAdaptaApp/geoLogger/logGuiEvents?json="+aLotOfJSONStuff;
encUrl = encodeURI(url,"UTF-8");
new Ajax.Request(encUrl, {
method: 'get',
onSuccess: this.sendQueueToServerSuccess( this,logConsole ),
[Code]...
The JSON string seems correct (I checked it with a validator) and it worked on an Ajax.updater (but i need a request now). Firefox keeps telling me:
[Code]...
The call always end up in the onFailure block. Full request here: [URL] It's very strange, Is there a better way to pass json objects to the server?

I have been trying to grasp the whole 'Pass By Value/Reference' thing for a few hours now. From what i can make out:
Passing by value will make a copy of the value, pass it as a function argument and the function will store the changes, the original value is not affected. So for example:
JavaScript Code:
var cost = 145;var postage = .3;var a = function() {return cost + postage;} //Using an Anonymous function for this
If you was then to pass the value of 'a' to a function argument it would copy and not change the original value.
If you pass by reference it will change the original value. When you pass a reference to a value through a series of different functions and the value is constantly being changed the change happens on the original value and can be seen outside the function.
The problem is i cannot think of how or why this would be used. I havn't got to develop many large applications so im trying to think of a few situations when passing by reference would be used.

I'm creating an AJAX page that is built using a PHP Class, ie the php looks a bit like this: PHP Code:
$wp_page->addjs('../var/savepolicies.js')
$wp_parser->page = "userpolicywindow.php";
$wp_parser->addlink("Home","../index.php","");
$wp_parser->addlink("Logout","javascript:logout();","");
$wp_parser->getpageid("501");
[Code]...
within this page that has been created, there is an AJAX tree folder which calls another page to be loaded into a DIV by AJAX again. Code:
[Code]...
I don't know why it doesn't work because the page has been loaded with the JS file, but as soon as the link is added afterwards it doesn't work. I take it this is because it doesn't know where to find the JS, but how can I overcome this?
