I have a file named sample.php, in which I have some JS code, and some PHP code. This is some sort of sample snippet of the code I have :
<!DOCTYPE html>
<html lang="en">
<script src="https://code.jquery.com/jquery-3.5.1.min.js" integrity="sha256-9/aliU8dGd2tb6OSsuzixeV4y/faTqgFtohetphbbj0=" crossorigin="anonymous"></script>
<head>
<script type="text/javascript">
var ThunkableWebviewerExtension = {
receiveMessage: function(fxn) {
var callbackFunction = function(event) {
if (typeof fxn === 'function') {
fxn(event.data)
}
};
document.addEventListener('message', callbackFunction, false);
window.addEventListener('message', callbackFunction, false);
}
}
</script>
</head>
<body>
<script type="text/javascript">
var value;
ThunkableWebviewerExtension.receiveMessage(function(message) {
value = message;
});
//sending the value with ajax
$.ajax({
url : "./sample.php", //same file
method : "GET",
data: {"name": value},
success : (res) => {
console.log(value);
},
error : (res) => {
console.log(res);
}
})
</script>
<?php
echo $_GET['name'];
?>
</body>
</html>
The problem is the PHP code doesn't print anything - Are there any error/bug I need to fix? Or is there a better method for accessing a JS variable in PHP?
Thanks! :)
Here's how you can access PHP code within in a <script> (without using AJAX):
<?php
echo"<script>";
include ('javascriptStuff.js');
echo'let x = '.json_encode($phpVariable).';';
echo"</script>";
?>
I have JavaScript code that send data to backend which when I place inline then work fine but when I place in external file it does not work. Meanwhile other JavaScript is working in external file.
<script>
$('#submit-ajax').click(function(event) {
console.log('working or not')
$.post(
'/order/detail/',
{
'test': 'hi i am here',
},
function() {
alert( "Data Loaded: " );
}
)
});
</script>
in external file code is:
$(document).ready(function(){
$('#submit-ajax').click(function(event) {
console.log('working or not')
$.post(
'/order/detail/',
{
'test': 'hi i am here',
},
function() {
alert( "Data Loaded: " );
}
)
});
}
I tried a simple example,
HTML code: Relative path of external JS you need to give
<!DOCTYPE html>
<head>
<script src="https://code.jquery.com/jquery-3.3.1.min.js" integrity="sha256-FgpCb/KJQlLNfOu91ta32o/NMZxltwRo8QtmkMRdAu8=" crossorigin="anonymous"></script>
<script src="(path of external js)\refJS.js"></script>
</head>
<body>
<div id="submit-ajax">
click me
</div>
</body>
In JS external file :
$(document).ready(function(){
$('#submit-ajax').click(function(event) {
console.log('working or not');
});
})
I have been trying to get the example from How to parse an RSS feed using JavaScript? working. My HTMl/script is below. The get request isn't working. I'm not getting any errors, just nothing happening.
Is this because of cross-domain issues? Can anyone spot the issue? Ultimately, I want to pull treasury prices from government rss feeds such as:
http://www.federalreserve.gov/feeds/Data/H15_H15_RIFSGFSW04_N.B.XML
Am I taking the right approach?
<!DOCTYPE html>
<html>
<head>
<script src="jquery-1.11.1.min.js"></script>
<link rel="stylesheet" type="text/css" href="style.css">
<script>
$(document).ready(function() {
alert('Jquery working fine');
$.get('https://stackoverflow.com/feeds/question/10943544', function (data) {
$(data).find("entry").each(function () { // or "item" or whatever suits your feed
var el = $(this);
console.log("------------------------");
console.log("title : " + el.find("title").text());
console.log("author : " + el.find("author").text());
console.log("description: " + el.find("description").text());
});
});
});
</script>

I search music with youtube data api. I use javascript and jquery and i have a problem.
Here is my code
<script src="http://code.jquery.com/jquery-1.11.0.min.js"></script>
<script src="<?php echo SITE_PUBLIC; ?>/bootstrap-3.2.0/dist/js/bootstrap.js"></script>
<script src="https://apis.google.com/js/client.js?onload=googleApiClientReady"></script>
<script>
function keyWordsearch(){
gapi.client.setApiKey('myapikey');
gapi.client.load('youtube', 'v3', function() {
data = jQuery.parseJSON( '{ "data": [{"name":"eminem"},{"name":"shakira"}] }' );
$.each(data["data"], function( index, value ) {
makeRequest(value["name"]);
});
});
}
function makeRequest(q) {
var request = gapi.client.youtube.search.list({
q: q,
part: 'snippet',
maxResults: 10
});
request.execute(function(response) {
$('#results').empty()
var srchItems = response.result.items;
$.each(srchItems, function(index, item) {
vidTitle = item.snippet.title;
vidThumburl = item.snippet.thumbnails.default.url;
vidThumbimg = '<pre><img id="thumb" src="'+vidThumburl+'" alt="No Image Available." style="width:204px;height:128px"></pre>';
$('#results').append('<pre>' + vidTitle + vidThumbimg + '</pre>');
})
})
}
keyWordsearch();
</script>
This code not working. Chrome console say "Uncaught TypeError: Cannot read property 'setApiKey' of undefined". But this code is working:
keyWordsearch() to
$(document).click(function(){
keyWordsearch()
})
I do not understand this issue. Thanks in advance
EDIT
My code run on jsFiddle.But not run my html file. My html file is here:
<!doctype html>
<html>
<head>

<body>
<div id="container">

<ul id="results"></ul>

<script>
$(function(){
function keyWordsearch(){
gapi.client.setApiKey('AIzaSyCWzGO9Vo1eYOW4R4ooPdoFLmNk6zkc0Jw');
gapi.client.load('youtube', 'v3', function() {
data = jQuery.parseJSON( '{ "data": [{"name":"eminem"}] }' );
$.each(data["data"], function( index, value ) {
makeRequest(value["name"]);
});
});
}
function makeRequest(q) {
var request = gapi.client.youtube.search.list({

maxResults: 10
});
request.execute(function(response) {
$('#results').empty()
var srchItems = response.result.items;
$.each(srchItems, function(index, item) {
vidTitle = item.snippet.title;

vidThumbimg = '<pre><img id="thumb" src="'+vidThumburl+'" alt="No Image Available." style="width:204px;height:128px"></pre>';
$('#results').append('<pre>' + vidTitle + vidThumbimg + '</pre>');
})
})
}
keyWordsearch();
})
</script>

Looks like, you haven't load the javascript library. That's why it can't find the reference.
You can add it like:
<script src="https://apis.google.com/js/client.js?onload=handleClientLoad"></script>
You can specify an initial function while calling the API like this: client.js?onload=init (see my example below). Besides no need of a doucument.ready() wrapper. I'm not sure why it works with your API key on my local machine but I guess it's some kind of magic that checks if the site is availible to the public - if true the referrer entries in your google account will get important - correct me on that if somebody knows whats exactly happening here.

var resultItems = response.result.items;
$.each(resultItems, function(index, item) {

In addition to all the answers which explain that you must specify and provide a callback function for the Google API client <script> loading line, I'd like to point out that it seems that the onload parameter will never run the specified function (at least in Chrome) when you load the Google API client.js from a local file (even though you are serving the HTML page via a webserver and not loading it from the file-system, which apparently seemed to be the only gotcha with the Google API JS client...).
e.g.:
<script src="/lib/js/client.js?onload=handleClientLoad"></script>
Although client.js will be loaded, this will never launch the handleClientLoad function when it's finished loading. I thought it would be useful to point this out, as this was a really frustrating thing to debug.
Hope this helps.
<script src="https://apis.google.com/js/client.js?onload=handleClientLoad"></script>
This MUST be called at the end, or at least after you define your method "handleClientLoad". This is its callback, and only after it was called - it means google api is ready. This is why you get gapi.client is null.
For the fun of it, you can use a timeout of a few seconds before using gapi.client and see it is not null anymore.
I have a script that i'm using to experiment a bit with jQuery since i just started learning.
the script is supposed to read a .json file and display some data in a div.
function jQuerytest()
{
$.getJSON( "books/testbook/pageIndex.json", function(result) {
$.each(result, function(i, field) {
$("div").append("<p>" + field + "</p>");
});
});
}
here is the html
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>Untitled Document</title>
<link href="styles/main.css" rel="stylesheet" type="text/css">
<script src="http://code.jquery.com/jquery-1.10.1.min.js"></script>
<script src="scripts/book.js"></script>
<script>jQuerytest();</script>
</head>
<body>
<div></div>
<figure id=fig><img onClick="jQuerytest()" src="figures/test620x620.png"/>
</figure>
</body>
</html>
but it doens't display anything.
If your JSON File is valid (You can test here: http://jsonlint.com/)
Use the success and error callback to finally get information why it's not working.
function jQuerytest(){
$
.getJSON( "books/testbook/pageIndex.json")
.success(function(result) {
$.each(result, function(i, field) {
$("div")
.append("<p>" + field + "</p>");
});
})
.error(function(error){
console.log(error);
});
}
