Hey everyone,

I'm trying to open an image with a button click using UI action (server-side script).

there is a way to redirect to a new window/tab?

Most of the solutions I found refer to the client-side.

this is my script: (the script work ok, but the image open in the same page)

var UrlImageSysId='';//image sysId for url param
var url='';//url for redirect
var currentImage = current.sys_id;//current image sysId from 'u_ts_image' table


var gr = new GlideRecord('sys_attachment');
gr.addQuery('table_sys_id',currentImage);
gr.query();
if(gr.next()){
UrlImageSysId=gr.sys_id;
}

url = 'https://hpindigodev.service-now.com/'+UrlImageSysId+'.iix';
action.setRedirectURL(url);

It is not possible to open a new tab or window in a browser by server-side code alone. You can only choose the next page shown.

When you think about it - the server cannot control the browser on a client's computer. If it could, that would be a massive security flaw!

You need to do it with both Client and Server Scripts.

This is how:

  1. Write a Client callable Script include called AttachmentAjaxUtil with your attachment fetch script that takes currentImage as a parameter and returns UrlImageSysId
    var AttachmentAjaxUtil = Class.create();
AttachmentAjaxUtil.prototype = Object.extendsObject(AbstractAjaxProcessor, {
	
	getAttachmentSysId: function() {
		var UrlImageSysId='';//image sysId for url param
		var url='';//url for redirect
		var currentImage = this.getParameter('sysparm_currentImage');//current image sysId from 'u_ts_image' table


		var gr = new GlideRecord('sys_attachment');
		gr.addQuery('table_sys_id',currentImage);
		gr.query();
		if(gr.next()){
			UrlImageSysId=gr.sys_id;
		}
		
		return UrlImageSysId;
	},
	
    type: 'AttachmentAjaxUtil'
});​
  2. Create a Client Script using GlideAjax to fetch that sys_id
    var ga = new GlideAjax('AttachmentAjaxUtil'); 
ga.addParam('sysparm_name','getAttachmentSysId');  
ga.addParam('sysparm_currentImage',g_list.getChecked()); 
ga.getXML(showPopup);  

function showPopup(response) {  
   var UrlImageSysId= response.responseXML.documentElement.getAttribute("answer"); 
   url = 'https://hpindigodev.service-now.com/'+UrlImageSysId+'.iix';
   g_navigation.openPopup(url); //this is preferable to window.open - window is not supported API, will probably be flagged in health checks

}​

    Let me know if you have issues with your GlideAjax.

Hi Paul,

I have a similar requirement but need to build URL by calling API. Can you please take a look on my post?

Hello!

I was having the same issue but instead of .openPopup I used the .open method and it worked!

 

Thank you so much!

 

Regards,

Pedro
