it's days that i'm trying to figure out how charset works.
I'm sending via form using ajax a string like: §test the output cannot recognize the "§" case.
This is my code:
var messaggio = $("input[name='messaggio']").val();
$.ajax({
url:"js/php/sendchat.php",
data:"messaggio="+messaggio,
type:"post",
contentType:"application/x-www-form-urlencoded; charset=ISO-8859-1",
beforeSend: function(jqXHR) {
jqXHR.overrideMimeType('application/x-www-form-urlencoded; charset=ISO-8859-1');
},
success:function(data){
$("input[name='messaggio']").val("");
$("body").html(data);
}
});
This on: sendchat.php
header("Content-Type: text/html; charset=ISO-8859-1");
And this on index where's my application:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"><head>
<meta http-equiv="content-type" content="text/html; charset=ISO-8859-1"/>
<script type="text/javascript" src="js/chat.js" charset="ISO-8859-1"></script>
What am i doing wrong?
Thank you in advance.
try this
beforeSend: function(jqXHR) {
jqXHR.overrideMimeType("text/html;charset=iso-8859-1");
}

I need to get the value of a javascript variable and put it into a mysql database. I am trying to use jquery ajax function in (test.html) to Post the variable to a separate PHP file (external.php). I'm not sure why it's not working, I would appreciate any insight. Here are my two files:
Here is test.html:
<!DOCTYPE html>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
<meta name="viewport" content="initial-scale=1.0, user-scalable=no">
<meta charset="utf-8">
</head>
<body>
<script>
$(document).ready(function () {
var longitude = "print a longitude";
$.ajax({
url: "external.php",
method: "POST",
data: { "longitude": longitude }
});
});
</script>
</body>
</html>
And here is external.php:
<?php
$longitude = $_POST['longitude'];
echo json_encode($longitude);
?>
The code below works perfectly fine for me:
The external.php file:
<?php
header('Content-Type: application/json');
$longitude = $_POST['longitude'];
echo json_encode($longitude);
?>
The test.html file:
<!DOCTYPE html>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
<meta name="viewport" content="initial-scale=1.0, user-scalable=no">
<meta charset="utf-8">
</head>
<body>
<script>
$(document).ready(function () {
var longitude = "print a longitude";
$.ajax({
url: "external.php",
method: "POST",
dataType: "json",
data: { "longitude": longitude },
success: function(data){
console.log(data);
}
});
});
</script>
</body>
</html>
Also, make sure you are not running your file as:
file:///C:/Users/XXX/Desktop/XAMPP/htdocs/test.html
If you run it like this you would get this error:
XML Parsing Error: no root element found
Location: file:///C:/Users/XXX/Desktop/XAMPP/htdocs/external.php
Line Number 5, Column 3:
What you need to do is run Apache and then run the file as:
http://localhost/test.html
Below is the screenshot of what I get:
What is the best way to display some content of a url (#somediv) on a div of my HTML Dreamweaver Phonegap
I am new on Phonegap DW and i want to display the weather values of this page:
http://www.catedralaltapatagonia.com/invierno/partediario.php?default_tab=0
In Java U used Jsoup, but i am not sure how do it on DW
I tried this code (AJAX and JSONP)
HTML
<!DOCTYPE HTML>
<html lang="en">
<head>
<meta charset="UTF-8">
<title></title>
<script src="js/jquery-1.5.min.js"></script>
<script src="js/load-json.js"></script>
</head>
<body>
<div id="output"></div>
</body>
</html>
JS
$(document).ready(function(){
var output = $('#output');
$.ajax({
url: 'http://www.catedralaltapatagonia.com/invierno/partediario.php? default_tab=0',
dataType: 'jsonp',
jsonp: 'jsoncallback',
timeout: 5000,
success: function(data, status){
$.each(data, function(i,item){
var landmark = '<h1>'+item.name+'</h1>'
;
output.append(landmark);
});
},
error: function(){
output.text('There was an error loading the data.')
}
});
});
i think you have to enabled CORS for this, you can enable cors via:
.htaccess
Header set Access-Control-Allow-Origin "*"
or via
.php (together with the codes)
<?php
header("Access-Control-Allow-Origin: *");
?>

Hey guys, I've tried everything.. Could someone please explain why i continue to get the "uncaught referenceerror: summonerLookUp is undefined"
I've tried switching the function to windows.summonerLookUp = function() { , but thats hasn't changed anything either. I've tried loading them within , within I've tried loading it at the end of the document, but i get the error "In XHTML 1.0 Transitional the tag cannot contain a tag ." is anyone able to explain whats going on here?
This is my index.js
function SummonerLookUp() {
var SumName
SumName = $("#SumInput").val();
if(SumName !== "") {
$.ajax({
url: 'https://na.api.pvp.net/api/lol/na/v1.4/summoner/by-name/' + SumName + '?api_key=',
type: 'GET',
dataType: 'json',
data: {
},
success: function (json) {
var SUMMONER_NAME_NOSPACES = SumName.replace(" ", "");
SUMMONER_NAME_NOSPACES = SUMMONER_NAME_NOSPACES.toLowerCase().trim();
summonerLevel = json[SUMMONER_NAME_NOSPACES].summonerLevel;
summonerID = json[SUMMONER_NAME_NOSPACES].id;
document.getElementById("sLevel").innerHTML = summonerLevel;
document.getElementById("sID").innerHTML = summonerID;
},
error: function (XMLHttpRequest, textStatus, errorThrown) {
alert("error getting Summoner data!");
}
});
} else {}
}
and my index.html
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta content="text/html; charset=utf-8" http-equiv="Content-Type" />
<title>LoLStats.GG</title>
<script language="javascript" type="text/javascript" src="../Javascript/index.js"></script>
</head>
<body>
Summoner Name
<br />
<input id="SumInput" />
<button onclick="summonerLookUp()">Click me</button>
<br />
<br />Summoner Level: <span id="sLevel"></span>
<br />Summoner ID: <span id="sID"></span>
</body>
</html>
The function SummonerLookUp is being called as summonerLookUp, javascript is case sensitive
Change
function SummonerLookUp() {
To
function summonerLookUp() {
JavaScript is case-sensitive. You named the function SummonerLookUp, but then you're trying to call summonerLookUp. Make them match.
I am having problems trying to activate a jQuery function from a PHP.
The following is my own test version.
index.php file
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Welcome to temp index</title>
<link rel="stylesheet" href="style.css" type="text/css" />
<script type="text/javascript" src="scripts/jquery-1.8.3.min[2].js"></script>
<script type="text/javascript">
$(document).ready(function() {
//posts info into the userinfo.php file
$.post('userinfo.php', { activate:"colourchange"}, function(data){
$('report').html(data);
});
//the function which is meant to be activated from the php file
function colourchange(){
document.body.style.backgroundColor = 'green';
};
});
</script>
</head>
<body>
<h1>hello</h1>
<div id="report">
</div>
</body>
</html>
PHP file I am attempting to call my jQuery function from
<?php
if( $_REQUEST["activate"])
{
$activate = $_REQUEST['activate'];
};
if($activate == 'colourchange')
{
// This is the code that I believe not to be working as this isn't
// activating the jQuery function to work. (The page background isn't changing colour)
echo "<script>colourchange(); </script>";
};
?>
Thank you to anyone who has an idea of what to do it is much appreciated.
I have now tried ...
<?php
require 'userinfo.php';
?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

<link rel="stylesheet" href="style.css" type="text/css" />
<script type="text/javascript" src="scripts/jquery-1.8.3.min[2].js"></script>

function colourchange(){
document.body.style.backgroundColor = 'green';
};
$(document).ready(function() {

$('report').html(data);
});
});
</script>
</head>
<body>
<h1>hello</h1>
<div id="report">
</div>
</body>
</html>
and the PHP index file is ...
<?php
if( $_REQUEST["activate"])
{
$activate = $_REQUEST['activate'];
};
if($activate=='colourchange')
{
echo "colourchange();";
};
?>
I don't exactly understand why you are using PHP to execute a jQuery function at all - perhaps this is just an oversimplified example. Assuming your primary goal is to have the PHP response trigger a specific Javascript function (and perhaps allow for the PHP response to trigger several different responses) you'd do something like this:
First change the callback from
function(data){
$('report').html(data);
}
to something like:
function(data) {
if (data.indexOf("colourchange") >= 0) { // php page returned "colorchange" or a string containing "colourchange"
colourchange();
} else if (data.indexOf("moodchange") >= 0) {
moodchange(); /// etc... you can add more trigger functions here
}
}
And second... just have your PHP page return "colourchange" instead of an HTML snippet:
if($activate == 'colourchange')
{
echo "colourchange";
};
Does that help?
you could try this-- example call the jquery function on success
$.ajax({
url: //the url,
data: //the data,
type: "POST",
success: function(data){
if(data == "ok"){
colorChange();
}
}
});
here the data will be the success result returned by the php code..
you can call a function depending on the data returned
I'd like to get a csv file from a url and transform it into an array.
So here is my code :
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="content-type" content="text/html; charset=utf-8" />
<title>Temperatures</title>
<script type="text/javascript" src="http://www.google.com/jsapi"></script>
<script type="text/javascript" src="jquery.js"></script>
<script type="text/javascript" src="jquery.csv-0.71.js"></script>
<script type="text/javascript" src="jquery.csv-0.71.min.js"></script>
<script type="text/javascript">
google.load('visualization', '1', {packages: ['annotatedtimeline']});
var csv_as_array = [];
function drawVisualization() {
$.ajax({
url: "data.txt",
aync: false,
success: function (csvd) {
csv_as_array = $.csv2Array(csvd);
},
dataType: "text",
complete: function () {
// use the array of arrays (variable csv_as_array)
// for further processing
}
});
[Google chart code]
}
google.setOnLoadCallback(drawVisualization);
</script>
</head>
<body style="font-family: Arial;border: 0 none;">
<div id="visualization" style="width: 1000px; height: 600px;"></div>
</body>
</html>
my data.txt is in the same folder as my .html file.
I know the block success: function (csvd) { } is not executed, because when I write alert("toto");, nothing happens.
Also, in the block complete: function () { }, I have written alert(csv_as_array.length); and it always shows 0.
The error is maybe just an import of a library missing ?
If success callback function was not called, it means error happened and error callback function would be called, if there would be one. You can try:
Adding error function, for example, a line like this error: function(jqXHR, textStatus, httpError) { alert('Error: '+textStatus); alert(httpError); }, to check for error.
Using absolute address in url
And you have a typo in the line aync: false - async, not aync.
