JavaScript - Linking Ajax In With Php In One Page
Hey, I have 3 bits of code, 2 of which I'm pretty sure are right [i know the php works, and the ajax looks fine], but one i'm having trouble with. Basically what I'm trying to do is use a link to call php function [calls a piece of text from a database]. Which worked fine. But then I tried to incorporate AJAX into the script to make change dynamically on the page, and I'm a little confused with it all. I've got the AJAX and PHP, [and an attempted page with a link on to try and call the function with AJAX] but so far it's not doing as it should. Wondered if anyone could show me where I'm going wrong with the whole 'linking together' thing? So far everything I've tried hasn't worked.
[hope this doesn't violate the forums 'don't dump your code' rule. But it's kind of all necessary] The AJAX [AJAX.js]: Code: function loadurl(generate.php) {
var ajax = false;
// Create the object:
// Choose the objecttype, depending on what is supported:
if (window.XMLHttpRequest) {
// IE 7, Mozilla, Safari, Firefox, Opera, most browsers:
ajax = new XMLHttpRequest();
} else if (window.ActiveXObject) { // Old IE-browsers
// Make the type Msxml2.XMLHTTP, if possible:
try {
ajax = new ActiveXObject("Msxml2.XMLHTTP");
} catch (e1) { // Else use the other type:
try {
ajax = new ActiveXObject("Microsoft.XMLHTTP");
} catch (e2) { }
}
}
// Retrieving the data from the page
if (ajax) {
alert("url:generate.php" + url);
ajax.open('GET', url);
// Sends request
ajax.send(null);
// Function that handles response
ajax.onreadystatechange=function(){
// If everything is OK:
if ( (ajax.readyState == 4) && (ajax.status == 200) ) {
// Returns the value to the document
alert(ajax.responseText);
}
}
} else { // AJAX is not useable
alert('It is not possible to connect, please update your browser.');
}
}

I've included the file names with extensions just in case it's something to do with those, but thanks in advance for any help. Greatly appreciated. Similar TutorialsI am currently using this template by flowplayer.org: http://flowplayer.org/tools/demos/sc...avigation.html The functionality I need is the ability to link directly to a specific ajax tab (i.e. Seagram Building, Barcelona Pavilion, New National Gallery). As of now they are just line items without any anchor tags. Any help would be much appreciated. gabe i have been looking all over the web and i can't get to where i need to be to finish my page. basically i have two pages and if someone clicks a specific link from the first page i want it go to the other page but load a specific page in the iframe on the second page. i know how to use javascript to make a specific page load into an iframe but not how to make the page load into the iframe on another page. all i need to know is how to do it for one page then i think i can build the decision structure around it to make it work for more than one link (hopefully). any help will be greatly appreciated. thanks. I have a simple script that will get the NWS forecast for any zip code and it opens it in a new tab. I would like it to open in an iframe on another page with in my website. I have come close, but not quite all the way yet. This will enter the forecast in an iframe on the same page as the input form. http://www.cavecountryweather.com/wxsearch.php How can it load onto this page from the form on the menubar? This menu is common on all the sites pages. I have seen solutions posted around the internet using javascript for similar issues, but I haven't been able to get any to work in my situation. My javascript skills are - none. Any help would be appreciated. . . . .Within my website (so I control all pages) I often make anchor-links from one page (call it currentpage.htm) to an anchor-link in another page (newpage.htm). Imagine that newpage.htm has two anchor-locations, one near the page-beginning (#high) and one near the page-end (#low). . . . .There is a problem when linking to newpage.htm#low (or an inside-the-page link to #low) because the page-end goes to the bottom of the browser window, and the location (#low) appears somewhere in the vertical middle of the browser window, so it's difficult for a user to know where they should begin reading, and they get confused. . . . .A low-tech solution is to "make the page longer" by adding space to the page-bottom with a series of <p> </p>, or with a tall blank spacer-gif. But this implies something false, it tricks a user into thinking the page is longer than it is, so they may think "this page is too long, I don't want to read that much" and they go away, or they "skim" when they could read more slowly. . . . .Is there a solution using javascript? . . . .If yes, I assume the javascript must be located within newpage.htm, because a command within currentpage.htm can't "tell another page" what to do. Is this correct? I'm not confident because I'm a novice with using javascript. . . . .So is there a way to say, within newpage.htm, "make the page longer by adding a blank spacer-gif to the page-end when an incoming link goes to newpage.htm#low" but to have this be temporary, so when newpage.htm is opened the next time normally (with a link to newpage.htm or to newpage.htm#high) the spacer-gif is gone? CraigR I've searched everywhere for help on how to do this... I have a website for tanning salon services. Salon A's page has links for 4 possible equipment choices -[I] (diamond, platinum, gold, bronze levels) on the Sunbeds page. Sunbeds page has 2 iFrames, top and bottom, that are changed by 4 functions - changediamond(), changebronze(), etc. based on the selection. I need to be able to click a link on the Salon page that will take me to the corresponding function on the Sunbeds page... Here's what I have so far: Salon A page Code: <a href="sunbeds.htm?javascript:changediamond()"><img src="images/nr_diam_sm2.jpg" alt="Diamond Level Sunbeds" /></a>

function changediamond()
{
parent.FRAME1.location="sb_top_ct1.htm";
parent.FRAME2.location="sb_bot_ct1.htm";
}
(thru)
function changebronze()
{

The links take me to the correct page but not the function. Once I'm there I can select the functions and the iFrame change works great. I'm just at a loss for passing along the data string ie sunbeds.htm?javascript"changediamond() I would certainly appreciate any help and advice you could share. I'm sure it's pretty simple but for a JS newbie, it's frustrating! hello i've followed this javascript and i'd like to link the text to one of my page.How do i place the ahref tag in the script.Appreciate your help http://www.javascriptkit.com/script/script2/neontext.shtml hey guys i have been trying for the last week to make a one of a kind login page. but i cannot figure out how to make the Slide bar initiate a Form submition i have made a sample page on jsfiddle shown here http://jsfiddle.net/Cav3maN/ZzwQq/embedded/result/ if your not farmiliar with jsfiddle just remove the embedded/result/ to see the source http://jsfiddle.net/Cav3maN/ZzwQq/ please feel free to modify the source and get it to submit. if your slider disapeers click the "Run" tab at the top. and when you get it successfully working click "Update" tab and send the new url on here for me to see. thanks very much. aslo this is a free source feel free to embed it in your site anywhere. thanks alot and please guy i beleve in you all lol im new to web coding and i wanna be successful so if you wish to show me exactly what you done to make this work i would love you for ever. We have an html page which brings in content dynmically using Ajax. So the page starts out with certain content, and when a particular link is clicked, the content is swapped out with new content. With this approach, the back button on the browser does not work, because the URL didn't actually change. How could a user bookmark the new page with the second set of content? Is this even possible?
OK, I've just been working with kwyl, trying to intergrate a like/dislike script to her site. There was an original script, and although bugged, it's almost the What works The user clicks the like/dislike icon. Ajax sends a request to PHP: Either the like/dislike gets inserted into the database. OR, if the user has already liked/disliked that post, an alert error gets returned. What doesn't work If you click to like/dislike a post, it won't appear (the current count is in brackets beside the icons) unless the page is refreshed. How would I use this along side Ajax for auto update? $data = mysql_fetch_object(mysql_query('SELECT `like`,`unlike` FROM posts WHERE id="'.$row['id'].'"')); It's used he Code: $data = mysql_fetch_object(mysql_query('SELECT `like`,`unlike` FROM posts WHERE id="'.$row['id'].'"'));
?>
<br />
<div class="vote">
<a href="javascript:;" onclick="doAction('<?php echo $row['id']; ?>','unlike');">
<input type="image" name="submit" src="images/down.gif" /></a>
(<span id=""><?php echo $data->unlike;?></span>)
<a href="javascript:;" onclick="doAction('<?php echo $row['id']; ?>','like');">
<input type="image" name="submit" src="images/up.gif"></a>
(<span id=""><?php echo $data->like;?></span>)
I hate javascript and this is utterly driving me up the wall. Any help would be much appreciated. If you need more informaton/code please ask. I have been searching online for hours, but it is possible I'm just not thinking of the correct keywords. I have included a basic illustration of the current setup (which does not work). The issue lies with the page that is the desired output. I have a far deeper issue which I have narrowed down to javascript on the final .asp page not loading at all. On default.asp, I am calling a function contained in 'ajax_call-contentselection.js' Code: <a onclick="func_displaycontents('restaurants'); return false">displayajaxcontent</a>
Honestly, I don't believe the following piece of code (ajax_call-contentselection.js) is relevant, as it is standard ajax code, but just in case: Code: function func_displaycontents(var_type){
var xmlHttp = GetXmlHttpObject();
var url = "../_include/ajax_display-contentselection.asp";
url += "?type="+var_type;
if (!xmlHttp){
alert ("Browser does not support HTTP Request")
return
}
xmlHttp.onreadystatechange=function(){
if(xmlHttp.readyState == 1){
document.getElementById("div_ajaxfillattractions").innerHTML = "<div style='padding-top:50px;color:white;width:930px;text-align:center;'><img src='../_images/ajax-loader.gif'/><br/>Loading...</div>";
};
if (xmlHttp.readyState==4 || xmlHttp.readyState=="complete"){
document.getElementById("div_ajaxfillattractions").innerHTML=xmlHttp.responseText;
}
};
xmlHttp.open("GET", url, true);
xmlHttp.send(null);
}
The other contents of "ajax_display-contentselection.asp" are displayed properly in "div_ajaxfillattractions" of "default.asp", but no javascript code on that page loads. If I use "ajax_display-contentselection.asp" as an include file on "default.asp", I get the javascript alert of 'Success', but when I initiate the AJAX it does not work, so I know there isn't a problem with the javascript. Please let me know if I sucked at explaining something, or more detail is needed. Thanks in advance, Matt I'm poking in the blind with javascript and hope that you can help with this issue. A javascript function is making a call to an external php file, which checks the compares the current time with a time stored in a mysql database. If a certain time passes, the php will send back instructions to redirect the user to a different page. The issue is that the page refreshes every time the is javascript function is executed. This resets any forms, or videos that the user is watching on the page. Here is the relevant code: Code: function checkTimer()
{
if (window.XMLHttpRequest)
{// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
}
else
{// code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange=function()
{
if (xmlhttp.readyState==4 && xmlhttp.status==200)
{
window.location.href = xmlhttp.responseText;
}
}
xmlhttp.open("POST","php/5minforpage10.php",true);
xmlhttp.send();
}
window.setInterval(checkTimer,15000);
Is there a way to achieve the goal of checking the time against the server time (via the php code) without refreshing the page? Thanks kindly! I have a website that is using ajax to keep the page up to date with the database information. I call this page through a file called start.php. Once index.php is loaded it has a menu with selections. I then want it to call a page called query.php in an iframe to update the information, but not open a new window. In the iframe the query.php will run and then redirect itself to blank.php. The code is as follows and any help would be much appreciated. I have tried several methods of doing this and they have been commented out because they didn't work or didn't do what I wanted them to do. I do not want to use window.open since IE doesn't work well with it. window.open does work by pop up windows but I want to stay away from them. The main code I am looking to get help on is in red under start.php. In start.php I will include the entire file. In index.php I'm only going to include the main sections I use for this snippit. In query.php I'm not going to include query.php since I beleive this file isn't important for this snippit. start.php Code:

Thanks in advance for all the help. I have a problem where the page doesn't expand when more results get loaded via jquery on a facebook style wall. Once more results get loaded the footer stays static instead of moving down. What's the best way to do this? hi, When I navigate to a page with Ajax on my iphone or ipad, it doesn't show up, page is just blank, I have checked for errors and there is no errors?! here is my Ajax code Code: function datecheckFunction(){
var datecheckRequest; // The variable that makes Ajax possible!
try{
// Opera 8.0+, Firefox, Safari
datecheckRequest = new XMLHttpRequest();
} catch (e){
// Internet Explorer Browsers
try{
datecheckRequest = new ActiveXObject("Msxml2.XMLHTTP");
} catch (e) {
try{
datecheckRequest = new ActiveXObject("Microsoft.XMLHTTP");
} catch (e){
// Something went wrong
alert("Your browser broke!");
return false;
}
}
}
// Create a function that will receive data sent from the server
datecheckRequest.onreadystatechange = function(){
if(datecheckRequest.readyState == 4){
var ajaxDisplay = document.getElementById('ajaxDiv');
ajaxDisplay.innerHTML = datecheckRequest.responseText;
}
}
var datepicker = document.getElementById('datepicker').value;
var queryString = "?datepicker=" + datepicker;
//Add the following line
datecheckRequest.open("GET", "http://www.affordableappliancerepairs.co.uk/admin/checkdate.php" + queryString, true);
datecheckRequest.send(null);

in my php page i have two text field i have to get the value by ajax/java script then by clickin radio button add or multy ply i have to show the result. how cain i do it?
he everyone please i want to know how to submit a form using ajax every 5 minutes without reloading page i have a huge form for exams and i need to submit the form without the need to wait until pressing submit because the user may wait to think about the answer a very long time.. so i want to submit the form and at the same time i cant reload the page as it is in normal submit form.. so how i can submit form in the background without letting the user knows that the form is submitted??? Hi, I am hoping I just need to be pointed in the right direction with this. I have Page1. When Page1 body onloads it uses Ajax to call PartA Within PartA I have a message board so members can write messages which will be sent to my database in PartA[1] and immediately posted for view on to PartA[2]. As I want to have my request to the server updating regularly I want to have PartA[2] on a timed loop to refresh - I do not need the content of PartA[1] to refresh. So the order of events would look like this: Page1 | onload call | v PartA / \ V V PartA[1] PartA[2] (loads once) (constantly refreshes) What I am not sure about is that I have <body> and <head> attributes in Page1 only. I have already used my body onload to call PartA (and can't use it to call PartA[2] before PartA has loaded anyway). I do not want the user to have to click a button or do anything to call up PartA[2]. So my question is how would I get PartA[2] to automatically load within PartA? I hope I have made this clear, but if I haven't let me know and I will try again. Hi all, I'm trying to link a java script file to a html file but it's not working. Any ideas? HTML: Code: <head><script type="text/javascript" src="newjavascript.js"></script></head> <body> <div id="myRadioGroup"> 2 Cars<input type="radio" name="cars" checked="checked" value="twoCarDiv" /> 3 Cars<input type="radio" name="cars" value="threeCarDiv" /> <div id="twoCarDiv" class="desc"> 2 Cars Selected </div> <div id="threeCarDiv" class="desc"> 3 Cars </div> </div> </div></body> JS: Code: $(document).ready(function(){
$("input[name='cars']").click(function() {
var test = $(this).val();
$(".desc").hide();
$("#"+test).show();
});
});
hey all. im fairly new to javascript and looking for a little help. first ive got this simple script that takes the value of a form and calls an image based upon the input. Code:
<script type="text/javascript">
function showImg() {
var val = document.getElementById("rightsphere").value;
document.getElementById("image1").src = "lensblank.gif"
if (val == 3) {document.getElementById("image1").src = "blank1.jpg"}
if (val == 4) {document.getElementById("image1").src = "blank2.jpg"}
if (val == 5) {document.getElementById("image1").src = "blank3.jpg"}
// and so on
</script>
<input type = "text" id = "rightsphere" size = "7" onblur = "showImg()">
<img style="position:absolute; left:090px; top:170px" id="image1" src="lensblank.gif" />
this calls up an image based on the submitted input when clicking on the actual image itself. i was wondering how i would go about getting the image1 to change when clicking another image (ie a button entitled 'calculate') thanks in advance update: nevermind. im an idiot. |
