Script Include and On change Client script using JS methods browser issue

[DPrasna]

Hi All,

I have a script include that returns the following result exactly as shown below with comma

"Development , Production"

Client Script (not working on Portal)

function onChange(control, oldValue, newValue, isLoading) {
	if (isLoading || newValue == '') {
		g_form.setVisible('column1',false);
		g_form.setVisible('column2',false);
		g_form.setVisible('column3',false);
		
		return;
	}	

	var prod = g_form.getReference('product');
	//alert(JSON.stringify(prod));
	//alert(prod.u_application_name);

	var ga = new GlideAjax('<scriptincludename>');
	ga.addParam("sysparm_name", "getCI");
	ga.addParam("sysparm_app_name", prod.u_application_name);
	ga.addParam("sysparm_sysid", newValue);
	//alert(newValue);
	//alert(newValue.getDisplayValue());
	ga.getXML(getResponse);

	function getResponse(response) {
		var res = response.responseXML.documentElement.getAttribute("answer");
		alert(res.toString());		
		
		//var res1 = res.toString();
		if(res.includes('Development')){	
			g_form.setVisible('column1',true);
			g_form.setVisible('column2',true);
			
		}
		if(res.includes('Production')){		
			g_form.setVisible('column2',true);
			g_form.setVisible('column3',true);
			
		}

	}

}

"

Now I need to have a client script to check the matches of the above returned results which is Dev/ Prod. I have the below script which works on Native UI but not on the Portal. It displays an error "There is a JavaScript error in your browser console " 

I need help to make it compatible and make it work on the Portal as expected.

Hi @DPrasna 

Can you comment out below line of code in your script and check if you are getting alert.

if(res.includes('Development')){	
			g_form.setVisible('column1',true);
			g_form.setVisible('column2',true);
			
		}
		if(res.includes('Production')){		
			g_form.setVisible('column2',true);
			g_form.setVisible('column3',true);
			
		}

Not sure but issue might be  because of res.includes().... 

Just for debugging you can check..

Hi Vishal, I tried however it doesn't show the alert even if I commented out the above lines
