JQuery :: Using A Function With Ajax And Variables?
Mar 30, 2010
Im trying to do the following thing, I have a function in javascript which I want to use to call anAJAX event, during this event the variable that is set in the function needs to be passed to the file called by the AJAX event. Basically I create 2 different versions of the same stuff inside the AJAX called files using the variables. But im running into some cross browser related issues, this all works fine in FireFox. However in Internet Explorer it sometimes works but gives javascript errors on line 99999ish. I have the following setup:
My index (currently calling startExample via onclick):
var exampleTest = 1;
function startExample()
{
example = exampleTest;
So this is nog working and i know that normal but i don't know how to do it. I just want those variables that are added to the link into the data: in de js-script. I think i might need to create an onclick function? but then how to "split" them?
I'm working with a few more variables than this, I'm working with 3 variables. What I'm wondering is should I use json_encode() on the php side. I will be using php validations, so I may return error messages in an array. How do I check whether I have error messages or true value.
I'd like to send in an associative array so I can have email = "error"; amongst a few others. So if email is the only one with error I will .append a message to the correct div id.
I am trying to assign a value to a java variable inside the script that I am calling via ajax but once the call is over it shows variable as undefined:
I have acollection of local variables populated via Flash movies and scripts, and now I need to submit an ajax post (can also be get, but prefer post). I have tried:
The problem with this is the encoding of the localParam1 and localParam2 sometimes breaks the normal & delimeters. An even more problem is I sometimes haveupwards of 25+ local variables that I need to submit. These inline +s makes it feel, and look, like one huge hack - not to mention the encoding. One last restriction: I cannot use any jquery plugins due to the company's policy. So, I'm looking for something small and light as a solution - not a plug-in. Isn't there an easy way to do this? ONe thought I had was to create a new <form> on the page, and insert the variables as new <input /> fields - and then finally submit the entire form. Again, a big hack + css
I'm reloading a div of a page using jQuery, but i need that every time that reloads (it reloads automatically every 10 seconds) obtains the get variables that i passed through the address bar
i declared 2 variables which i want to use depending on a conditional statement inside a jquery function unfortunately they don't seem to be working. do they need to be globals?[code]i know for a fact that the code works, when i add an alert inside the conditional statement it pops up fine, but these variables don't seem to get their values applied.
I've got the following source code: function MyMenu()
[Code]...
I wish to execute the lambda function given at menuEntries[i].action. The list is build, but at a click i've got the error that menuEntries[i] is not defined. What should I do? I think
i have this problem in passing values to a variable in a jquery function.
i have a js variable that accepts a certain value and then i want to pass this variable in the jquery function.
For example, this is my script: var autoScrollBool = "true" var autoScroolInt = "10" (seconds) stepcarousel.setup({
[Code].....
i want to replace the value of autostep: {enable:true to enable: utoScrollBool(the variable i created) , when i tried to assign it as is, its not working.
I want to call a javascript function when a <span> is clicked, pass two variables to it, and then use jquery to hide that span.
A simple example is:
The variables (1,3) & (8,9) are loaded dynamically with a php script. Adding the two variables together isn't the intent of the script, but it seems the simplest way to explain what i'm after.
So how do you get $(this) to work in a function that has to have variables passed to it?
is there a way in jQuery to bind variables to function calls similar as prototype.js does it? See [URL]
E.g. in the slideUp method of jQuery you can specify a callback that is called after the effect has finished. I would like to bind a variable to this call so that it is used inside of this callback as a closure.
Is there a way to "pass" an XMLHttpRequest object to the callback function for onreadystatechange? Or a way to access it from onreadystatechange? I would like to avoid the use of a global variable...
Example:
/* How do I get rid of this global variable? */ xmlHttp = new XMLHttpRequest();
function myFunc() { ... xmlHttp.onreadystatechange = myCallBack; ... }
function myCallBack() { if (xmlHttp.readyState != 4) { return; }
I'm working on an AJAX calendar. Visitors can select a date, fill out a form to request a meeting, and click submit. Here's what's crazy. My calendar has two parts: the top part displays the meetings for each day as well as the form and the bottom part displays the actual calendar. When you click submit, the top part update correctly, but using the same variable, the bottom part is incorrect. After doing some debugging I found that the variable for some reason changes between the php and javascript.
The rest of the code is unimportant because it does not pertain to my question. I have a callback function (show_cal) that uses eval() to parse the javascript built on the server. The getEvents function works without a hitch. The getCalendatMonth does not and here's why: in the php, the echo "alert(\"" . $date . "\");"; shows the correct response (2009-28-09) however the alert(date); in my Javascript only returns a random year (1975, 1976, 2000). Does anyone have any suggestions about why the two alerts would be different?
Here's the code.
java script:
function getCalendarMonth(date) { if(http.readyState ==4) {
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.
Now i have a doubt, how i can pass the variables $var and $var1 with ajax to a PHP file? to make sql querys and replace the values of $var and $var1[code]...
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].....
I will explain this the best way that I can. I have a form that can be filled out and once the submit button is pressed, a lightbox pops up to prompt a thank you page. The thank you page is called verify.php. Basically when the user fills out a form and presses the "submit" link, a lightbox pops up saying "thanks". I need the form values to be displayed in this lightbox. Since my values aren't actually being sent using the POST method, the verify.php is does not show my confirming value box (ex: Thank You Brad Heckle (this is the $fullname variable) for submitting an application.). This verify.php is called using AJAX and displays without loading a new page on the index.php when "submit" is pressed. Since php needs the variable to be passed through the POST method so that it can grab them, AJAX is causing some problems.
I have used AJAX lots before and I wondered if it was possible to set variables from an AJAX file E.g. an ajax file could set var set1 = 10; var set2 = 55; with both variables coming from an external file called by AJAX. Which JS side perform the request and the format of the file that is requested.
how can I make ajax pass variables to php, I been trying to use $POST but it�s not working for me, I have this script
Code JavaScript: function get_school_data() { var xmlhttp;[code]....
What I am trying to achieve is to send the value of country to php and have it stored in a variable so I can then select a different table in the database, but when I do it the way I am, it does not work, as it gives me an undefined variable
I am using ajax in my site and want to implement a friend request button. When a user clicks this button their userid and the userid of the friend thwey are requesting will go into a table called notifications in my mysql database. This works fine in regular html/php with javascript disabled but not when using javascript/ajax.
Here's my code which may clarify things:-
Code:
<script type="text/javascript"> function makeRequest(friendrequestloggedinuserid, friendrequestuserid) { if (window.XMLHttpRequest)
[Code]....
The above code works perfect if javascript is disabled and the button is clicked as the new row is inserted into the database however if javascript is enabled the alert shows inidicating the ajax file is working but the new row is not inserted. Is this something to do with the POST process between my javascript code and my ajax_processrequests.php file?
BTW $loggedinuserid and $userid are retrieved earlier on in my code but showing how they are retrieved is irrelevant to this because I know they are present at the point of the above code.
