I am having difficulty with a specific JQuery $.post call to a PHP-based processor. I created a test page with the code below located here: http://goo.gl/Bg7H2u
Note this is located on a subdomain, but we are not doing cross-domain posting. Everything should be included on the subdomain.
There do not seem to be any JS errors as reported in the error console.
The processor /get-data.html is the general purpose PHP processor, and, if you load the processor page with the right value, it returns a dataset from the MySQL database in JSON format. We have this working on the main domain without issue, and other $.post calls seem to work OK from this subdomain (not to this /get-data.html processor, but other processors that process form content).
See the actual processor output here: http://goo.gl/yOzrm2
I must be missing something obvious, but I am coming up empty. Thoughts?
Here is the code:
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=320px, initial-scale=1">
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
<script type="text/javascript">
var prices;
$(document).ready(function(){
$.post( "/get-data.html", { table: 'prices' },
function( data ) {
prices = data;
alert(prices);
}, 'json');
});
</script>
</head>
<body>
<div style="overflow-x: hidden;" id="divMain">
</div>
</body>
</html>
Thanks for any advice you can provide.
If you do View Source on the processor output, you'll see that your script is returning:
<p>{"Basic Plan":["349"],"Basic":["349"],"Premium Plan":["549"],"Premium":["549"],"Standard Plan":["429"],"Standard":["429"],"Bonus Plan":["175"],"Additional Central AC System":["99"],"Additional central heating system":["99"],"Central Vacuum":["99"],"Whole home humidifier":["49"],"Pool (in-ground)":["179"],"Spa (in-ground)":["179"],"Septic System":["99"],"Sump Pump":["99"],"Well pump":["99"],"Whole home water softener":["99"],"Lawn sprinkler system (in-ground)":["99"],"Wine refrigerator":["49"],"Ice maker (free standing)":["49"],"Home phone (unlimited)":["49"],"TV Protection (Flat screen up to 60 inches)":["99"],"PC Protection (laptop or desktop)":["49"]}</p>
There's <p> at the beginning and </p> at the end. This is not valid JSON. You need to fix the server script so that it doesn't print anything other than the JSON (whitespace is OK, that's it).
1.confirm that /get-data.html is the correct relational url for your file location.
If you navigate directly to the /get-data.html, does it produce the results that you are after.
try running the same code without , 'json' and see if it works.
hope this helps

I want to process a GET extension in a HTML page and not a PHP page.
I have looked through the internet and not found anything.
URL = examplesite.com?id=1234
I assume this would go to the index page on the domain. As the index page is a HTML page, is there a way to get the details of the extension transferred to another link I have in the html script that emails me when someone looks at the site.
<script src="trigger.php">
</script>
This way I can customise the extension to know where the person found me. id=1234 is from twitter, id=2345 from FB etc.
Then i could place the extension onto the script to send me the email.
<script src="trigger.php?id=1234">
</script>
Is there a way to get the HTML page to process extension and pass it on in a variable of some sort.
Thanks in advance
Robert
You can do it in Javascript in the HTML. window.location.search contains the query string from the URL.
You can then use an AJAX request to send the query string to your server script.
<script>
$(document).ready(function() {
var script = 'trigger.php' + window.location.search;
$.get(script);
});
</script>
This is not possible with plain HTML. By definition, HTML is not dynamic. It can't process anything you want. However, there are three options.
Firstly, you can use JavaScript and AJAX calls to make another HTTP request to examplesite.com/processID.php (or another PHP page) which will process the request.
Another way to use JavaScript would be to use a client side API such as MailChimp to send the email directly from the users computer.
Or you could just redirect your root page for your domain examplesite.com to lead to index.php. I'm sure that's very easy to configure in mainstream servers such as Apache or Nginx. Otherwise please ask another question on Server Fault about how to set this up using your server.
If you are using a PHP hosting provider, they should also be able to help redirect the root page. If you don't have any access to PHP on your hosting provider, you're out of luck. You must only use the second option.
Do it with ajax
<form id="form1">
<input type="text" />
<button type="submit" id="sendforms">send</button>
</form>
<script src="https://code.jquery.com/jquery-3.2.1.min.js"></script>
<script type="text/javascript">
$(document).ready(function () {
$("#sendforms").click(function() {
var combinedFormData = $("#form1").serialize();
$.get(
"trigger.php",
combinedFormData
).done(function(data) {
//alert("Successfully submitted!");
$("#result").html(data);
}).fail(function () {
//alert("Error submitting forms!");
})
});
});
</script>
Since from 2 months I am trying to implement google maps.But still am not done with it.
Question 1,Question 2,Question 3 were my previous doubts.
After a long research I got to know that:-
"Google accepts only 10 requests/sec.If it receives more, then it generates a status 'OVER QUERY LIMIT'.Solutions are to buy that API(not sure about it completely) OR Generate a key with Google Maps which will accept 25000 req/day(Suitable for my requirement)".
Now I have a key.The issue is "It's usage".
Code snippet:
1.
<meta charset="UTF-8" />
<script src="http://maps.google.com/maps/api/js?key=AIz************************************"></script>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
<script>
$(function () {
//The list of points to be connected
<?php
***********
This gives an alert:
"The provided Google API key is invalid or this site is not authorized to use it"
2.
<meta charset="UTF-8" />
<script src="http://maps.google.com/maps/api/js?sensor=true?key=AIz************************************"></script>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
<script>
$(function () {
//The list of points to be connected
<?php
***********
Usage of sensor removes the alert but it still gives the status 'OVER QUERY LIMIT'.
As mentioned here I've tried editing the credentials and all but nothing works out.
Working fiddle
Kindly help me out in solving this. If possible give any direct steps, instead of so many links and indirect instruction/comments.
Thank you
I think I should stop using SO...
This answer is for the beginners like me.
1.No need of sensor in Google API V3
2.Use browser key like this - <script src="http://maps.google.com/maps/api/js?key=AIz************************************"></script>
3.In Edit allowed references under credentials give the complete path.

I have java script file that reads in a csv file, and has many functions to to visualize the data differently, using d3. I want each visualization to be displayed in different html pages. Ive made every html page, refer to the javascript file. Each page also has its own script that calls functions from the referred javascript file.
The problem, I am facing is that when ever I go to a new page, the function gets called before the data being read. Only works when refreshing the page. I there a way to just read the data in once, and every page can access it.
If you look at the code below, callingFunction() returns undefined (maybe because data is not stored in var data?) The callingFunction() works fine when the page is refreshed.
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>D3</title>
**<script src="my.js"></script>** //my script file
</head>
<body>
<script>
callFunction(); //uses var data defined in my.js
</script>
Here is the "my.js":
var data;
function data(file){d3.csv("file", function (error, data) {
ds = data;
callFunction();
}
load your script after the target DOM :
<canvas></canvas>
...........................
<script type="text/javascript"></script>
Use angularJs Js library: it organize your js code according to MVC design pattern.
If you have more than one method to implement a business logic , Use console.time & console.timeEnd to evaluate code performance .
console.time('anID');
// Here your code
console.timeEnd('anID');
I have a url which gives json data...
I want to hit that URL from javascript but I am getting this error :
character encoding of the plain text document was not declared. The document will render with garbled text in some browser configurations if the document contains characters from outside the US-ASCII range. The character encoding of the file needs to be declared in the transfer protocol or file needs to use a byte order mark as an encoding signature
Code :
function a(){
$.getJSON(url,function(data) { alert(data);});
}
full code :
<html lang="en">
<head>
<meta http-equiv="Content-Type" content="text/html;charset=utf-8" ></meta>
<script language="JavaScript" type="text/javascript" src="jquery-1.7.1.min.js"></script>
<script>
function a(){
$.getJSON(url,function(data) { alert(data);});
}
</script>
</head>
<body>
<input type="text"/>
<input type="submit" value="search" onclick="a()"/>
</body>
</html>
Your code seems correct.
Are you making a fully qualified URL call?
If you are making a fully qualified URL call, make sure of the following.
You are calling the same domain(same server). You can not make a
simple JSON call to another domain.
If you want to use a cross domain call, you'll have to use JSONp
Update:
This is not working since it is a cross domain call.
Work around for this
JavaScript
Create a function
function getMyData(data) {
alert(data);
//Do the magic with your data
}
Server side
On server end wrap your data inside function syntax
getMyData("Enter your data here");
JavaScript
Then create a script tag and add a link to your cross-domain page
<script type="text/javascript"
src="cross ref url">
</script>
For reference: wikipedia
EDIT: Another option is Create a proxy on your domain. ie create a page in your domain which internally calls the cross-domain page and return the same data to your Ajax call.
EDIT: I have discovered that this is a 405 error. So there is something going on with the webserver and handling POST methods.
I am having a strange occurrence. I have identical javascript code on both my test environment and production environment.
The test environment functions, and the production does not. Here is my identical code.
<html>
<head>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js"></script>
<script type="text/javascript" src="http://cdn.jquerytools.org/1.1.2/jquery.tools.min.js"></script>
<script type="text/javascript" src="./js/jquery.scrollTo-min.js"></script>
</head>
<body>
<div class="content" id="content">
<a id="changeText" href="test.html">Change</a>
</div>
<script>
$(document).ready(function() {
$("#changeText").live('click', function(){
var url = $(this).attr("href");
$("#content").load(url, {var1:Math.random()*99999},function(){
alert(url + " loaded");
});
$.scrollTo("0%", 400);
return false;
});
});
</script>
</body>
</html>
Both environments report that
alert(url + " loaded");
is happening. But only my test environment actually displays the change.
The production webserver has "test.html" available in the correct location.
Are you sure the scrollTo script is being included on the production server ( or am I misinterpreting what you mean by change ) ? Perhaps try a root relative path instead of './js'? I would check Firebug's script tab to ensure it is being included.
405 errors mean that the URL you're sending to isn't expecting you to send the data in that manner. For example, if you're sending a POST request to a URL that's only designed to handle a GET request, you'll get this error.
My guess is whatever server you're running on is set up to not allow POST data to be sent to a page with a .html extension, causing the error you're seeing. Try changing the extension to a .php, .aspx, etc, and see if that helps.
