type error : window.open is not a function

Question

I have written a script to open a page in new tab on click of a command button. Unfortunately I get the following error:

window.open is not a function()

I have not created any variable named "Open" which may have over written the open() function.

My script is like this

<script>  
function newpagePDF() {
          alert('Hi11');
          var stringcase = '{!caseid }';
          var newpage = window.Open('/apex/ZEB_RMA_Pdf?CaseId='+stringcase );
    }

</script>

My command buton is :

<apex:commandButton value="Generate Pdf"   onclick="newpagePDF();"/>

Answer 1

Try following statements:

window.open(('/apex/ZEB_RMA_Pdf?CaseId='+stringcase), window.name, "height=600,width=700");

or

window.open(('/apex/ZEB_RMA_Pdf?CaseId='+stringcase), '_blank', "height=600,width=700");

Answer 2

The reason actually is pretty simple: Unlike apex, javascript is case-sensitive. So instead of using window.Open, use window.open will resolve your issue

Answer 3

Change the window.open as below,

var newpage = window.Open('/apex/ZEB_RMA_Pdf?CaseId='+stringcase ,'_blank');

_blank - opens page in new tab

Try this.It will work..
