Onclick the button to export excel in XPages

问题

I found the code on the website: https://www.xpagedomino.com/2015/02/xpage-export-to-excel-using-javascript.html

Now I have :

1. a view
2. one button

---

I want to use the button to export the excel.

The following is I already tried the code：

In the button(Client-side) :

var viewPanel1Id = "view:_id1:viewPanel1"
var htmltable = document.getElementById(viewPanel1Id);
var html = htmltable.outerHTML;
window.open('data:application/vnd.ms-excel,' + encodeURIComponent(html));

But the button was no response...

How can I export to excel?????

The following is the code of XPages

 var html = viewPanel.outerHTML;
window.open('data:application/vnd.ms-excel,' + encodeURIComponent(html));}]]>

Your Button executes ServerSide Script. When using <xp:this.script> it worked for me.

    <xp:button value="Export5" id="button5">
      <xp:eventHandler event="onclick" submit="false">
        <xp:this.script><![CDATA[ 
                var viewPanel = document.getElementById("#{id:viewPanel1}");
                var html = viewPanel.outerHTML;
                window.open('data:application/vnd.ms-excel,' + encodeURIComponent(html));]]>
  </xp:this.script>
    </xp:eventHandler>
</xp:button>

This may not fix your problem, but the line below is a better way to reference an element by its id in csjs:

 var viewPanel1Id = document.getElementById("#{id:viewPanel1}")
