sushil353 — Wed, 30 Nov 2011 10:41:29 GMT

Hi All,

I am new to this functionality of qlikview. i have a function to call a webpage using post method. but how do i call it using a button in my qlikview dashboard as it is written in javascript and edit module of qlikview is not supporting javascripts.

Please help me out to solve this issue. i have not provided the url in action due to security reasons..

function callCND(){

var myForm = document.createElement("form");

myForm.setAttribute("action", "http://xyz");

myForm.setAttribute("method", "POST");

myForm.setAttribute("target", "_blank");

var myunitrpt = document.createElement("input") ;

var myexid = document.createElement("input");

myunitrpt.setAttribute("name", "UNITRPT") ;

myunitrpt.setAttribute("value","history");

myForm.appendChild(myunitrpt) ;

myexid.setAttribute("name", "EX_ID") ;

myexid.setAttribute("value","1093981623");

myForm.appendChild(myexid) ;

document.body.appendChild(myForm) ;

myForm.submit() ;

document.body.removeChild(myForm) ;

}

Thannks in advance

Hi Sushil,

Maybe this one cannot help you, but we need to try first by Go to Actions ==> Add ==> External ==> Run Macro ==> Put the function name in the box

It sounds like you want to display a webpage within a qlikview app. for that you would need to look into extensions. Qliktiech has provided a WebPageViewer extension example in their example code. Have a look at that.

Button->Properties->Go to Actions ==> Add ==> External ==> Run Macro ==> Put the function name in the box

Control +M _> check on javascript -> write here your function.

Jscript and Javascript are pretty much equivalent. However, I don't think you can manipulate the DOM (browser) document object directly from module code. You have a few alternatives I can think of:

1. Use a GET url instead with a button Action External->Open URL.

2. Use the module, but use XmlHttp Post. (http://www.w3schools.com/ajax/ajax_xmlhttprequest_send.asp)

3. Code it up in an extension object.

Hi Sushil,

You can't invoke javascript functions from a QlikView button.

The Extension Objects allows you to to create custom visualizations in QV so you could create your own button in your script instead.

This is a small sample someone wrote, can't remember who, that you could look at.

Download and doubleclick the postdata.qar file, Enable Webview in qlikview, right-click an add sheet object, drag and drop your post data extension into your app.

If you want to look at the code you can find it at C:\Users\%username%\AppData\Local\QlikTech\QlikView\Extensions\Objects\PostData

Hi Sushil,

I agree that Alexander's suggestion is best. If you want to POST and then display the output, an Extension is the way to go.

Hi I'm Velu very new to QlikView please any one tell me how to develop a dashboards in web browser using java(jsp)

please help i tried but couldn't .in some manuals mentioned QlikView Java client how to use that..

Re: how to call a javascript function in qlikview ??

rwunderlich — Mon, 06 Aug 2012 18:36:00 GMT

The java client is no longer supported.

Any Qlikview dashboard can be displayed in a browser -- by using Qlikview Server -- without additional coding.

It is possible to call a JavaScript function from a QlikView Button by following these steps:

Create a button and choose Actions - External - Open URL
Enter your JavaScript function in the format = 'javascript: functionname(parameters); true()'.
Check the box 'Open in same window'
See attached for an example of launching a JavaScript popup.

Note that this will only work for javascript functions and not for user defined functions.
