Ajax Code To Display Data - ajax

I wrote this code in javascript to disply information in this page (Normal_Info.php),
but unfortunately it did not work. If anyone can help me I will be grateful
<html>
<head>
<script language="javascript">
function ajaxFunction()
{
return window.XMLHttpRequest ?
new window.XMLHttpRequest :
new ActiveXObject("Microsoft.XMLHTTP");
}
function Go_there()
{
var httpObj = ajaxFunction();
httpObj.open("GET","Normal_Info.php", true);
httpObj.send();
httpObj.onreadystatechange = ChangedState()
{
if (httpObj.readyState == 4 && httpObj.status == 200)
{
document.getElementById("result").innerHTML=httpObj.responseText;
}
}
}
</script>
</head>
<body>
<form id=ff>
<input type=button value=Hi OnClick=Go_there() />
</form>
<div id=result>
</div>
</body>
</html>

i suggest using jquery http://jquery.com/
<script src="jquery.js"></script>
<script language="javascript">
$('#ff').submit(function() {
$.ajax({
url: 'ajax/test.html',
success: function(data) {
$('#result').html(data);
// alert('Load was performed.');
}
});
});
</script>

Route::get('/ajax',function(){return view('online_help');});
Route::post('/getmsg','Hello#ajaxl');
When I click + or - the value doesn't change and no error.
Please any one help me
The problem is very small.
This line:
$("cart_quantity_input").val(data.qty);
just you forgot to add . before cart_quantity_input
So change it to be :
$(".cart_quantity_input").val(data.qty);

Your API returns JSON, you don't need use JSONP, just change dataType from jsonp to json
$.ajax({
type: "GET",
dataType: "json",
....
});
and in showResult set only response because response contains Array of Objects and does not have results property
this.setState({
data: response
});

Load data in a popup using Ajax

I'm using magnificient popup on my website, and I would like to execute ajax function when a link is clicked and the result of the query should be the content od the popup.
this is my code (I'm pretty new in JQuery) :
<script>
function showPics(str)
{
if (str=="")
{
document.getElementById("displayPics").innerHTML="";
return;
}
xmlhttp=new XMLHttpRequest();
xmlhttp.onreadystatechange = function()
{
if (xmlhttp.readyState==4 && xmlhttp.status==200)
{
document.getElementById("displayPics").innerHTML=xmlhttp.responseText;
}
}
xmlhttp.open("GET","getpics.php?q="+str,true);
xmlhttp.send();
}
</script>
<a class="1-popup" href="#">Guerlain</a>
<script type="text/javascript">
$('a').click(function() {
showPics($(this).attr('class').charAt(0)), //Ajax function call
$(this).magnificPopup({ //Popup call
type:'inline',
midClick: true,
closeBtnInside:true
});
});
</script>
<div id="displayPics"><b>Pictures will be listed here.</b></div>
The content is loaded, but the popup not.
Here's the solution of my issue :
<a class="1-popup" href="#displayPics">Guerlain</a>
<script type="text/javascript">
$('a').click(function(){
showPics($(this).attr('class').charAt(0)) //Ajax function call
});
</script>
<script type="text/javascript">
$('a').magnificPopup({ //Popup call
type:'inline',
midClick: true,
closeBtnInside:true
});
</script>
<div id="displayPics" class="white-popup mfp-hide"><b>Pictures will be listed here.</b></div>
Thank you all.

FadeOut effect not calling AJAX function code

I'm learning some basic JQuery that appends Ajax queried data from a text file into a div element. The program doesn't work when the AJAX code is added and when the function is called from the fadeOut effect. Else the fadeOut works fine.
Am I supposed to code the AJAX in another file and link it? What is wrong in this code? Sorry if the title of the question isn't precise.

You need to pass the reference of myFunction to the callback. Your current method is calling your function on page load instead. Try this:
$("#pic1").click(function() {
$("#div1").fadeOut("slow", getData); // note: no () brackets
});
function getData() {
$.get("testfile.txt", function(data) {
$("#myDiv").html(data).fadeIn("slow");
});
}

<button id="b1" onclick="main_draw('CQ1','va2apsap010',10000)">Display Content</button>
</body>
</html>
Above is an entire code which makes AJAX calls upon clicking on "Display Content" and after that it refreshes content of div "ajdiv4" by calling function "draw_pie". The only problem with this is that when it refreshes, it moves the pie graph all the way to the left. I would like it to stay and update it in the current position. Please help if any of you know what is going on here, Thanks.
Have you tried specifying the dimensions of your DIVs? With your current code, you could probably do:
<style>
#ajdiv1, #ajdiv2, #ajdiv3, #ajdiv4 {
height:200px;
width:200px;
}
</style>
Alternatively, add a class attribute to simplify things:
<style>
.chartContainer {
height:200px;
width:200px;
}
</style>
If you have a working version up, or can post something on JSfiddle, that would make things easier to troubleshoot.
