QlikView Extenssion - How to make an Ajax call (in Javascript)

Mon, 26 Jan 2026 16:26:21 GMT

Hi everybody,

I start with QlikView extensions and I am facing a problem. I can not, since an extension QlikView, to make an Ajax call. I simplified my example to target a simple text document, which I would like to dynamically display content in the HTML body of extenssion. I'm using JavaScript (with JQuery) for scripting behavior.

I have a Definition.xml like that :

<?xml version="1.0" encoding="utf-8"?>

</ExtensionObject>

And a Script.js, like that :

Qva.AddExtension('HelloWorld', function() {

Qva.LoadScript("Extensions\Objects\HelloWorld\jquery.js" , function() {

//alert("jQuery up"); // work!

});

var html = "";

html += "<H1 style='text-align: center;'>"+this.Layout.Text0.text+"</H1>";

html += "Before";

$(document).ready(function() {

$.ajax({

type: "post",

url: "Extensions\Objects\HelloWorld\texte.txt",

dataType: "text",

async : false,

success: function(data, textStatus, jqXHR){

html += ""+data+"";

error: function(XMLHttpRequest,textStatus, errorThrown){

alert("error : " + textStatus + "\n" + errorThrown);

}

});

html += "After";

this.Element.innerHTML = html;

});

The file texte.txt is in the same directory, and It contains :

Lorem ipsum dolor sit amet, consectetur adipiscing elit. Sed non risus. Suspendisse lectus tortor, dignissim sit amet, adipiscing nec, ultricies sed, dolor. Cras elementum ultrices diam.

The Result is :

1) On refresh :

2) After clicking OK on the popup box :

Does anyone have an explication or some tips, I'll be happy.

Thanks you so much per advance.

To get data from server you should use GET request (not POST - instead of type: "post" you should use type: "get"). Be sure you have properly formatted url. I think, your url "Extensions\Objects\HelloWorld\texte.txt" is wrong. Try like this: url: Qva.Remote + "?public=only&name=Extensions/HelloWorld/texte.txt"

Thanks you so much! It's work perfectly.

Have a very nice day.

If it helps others, my code is :

$.ajax({

type: "get",

url : Qva.Remote + "?public=only&name=Extensions/HelloWorld/texte.txt",

dataType: "text",

async : false,

success: function(data, textStatus, jqXHR){

html += ""+data+"";

error: function(XMLHttpRequest,textStatus, errorThrown){

alert("error : " + textStatus + "\n" + errorThrown);

}

});

$.ajax call is asynchronous. So, your html variable will contain 'BeforeAfter' text only before you will get some result from ajax request.
