how to call a javascript function in qlikview ??

[sushil353]

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.

this is a javascript function to  call a webpage using post method...

my problem is... as i am not able to invoke this function using edit module of qlikview....

If u know how to call a webpage using post method using VB script which is supported by qlikview. then my problem will be resolved

Thanks

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.

hope this may help you

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
