try this

function onChange(control, oldValue, newValue, isLoading) {
	// Check if loading or newValue is empty
	if (isLoading || newValue === '') {
		return;
	}

	// Create GlideAjax instance
	var ga = new GlideAjax('BISwCatDecomUtilAJAX');
	ga.addParam('sysparm_name', 'multilinetextversion');
	ga.addParam('sysparm_sys_id', newValue);

	// Use getXML method instead of getXMLAnswer
	ga.getXMLAnswer(function(answer){

		alert("Suresh is " + answer);

		// Use meaningful variable names
		var multilineTextVersion = answer;
		alert("The input is " + multilineTextVersion);

		var parts = multilineTextVersion.split(/\),/);

		if (parts.length <= 1) {
			g_form.setDisplay('sw_cat_item_removed', true);
			g_form.setReadOnly('sw_cat_item_removed', true);
		} else {
			// If there are more than one part
			g_form.setDisplay('sw_cat_item_removed', false);
		}
	});
}

Still i got javascript console error 
Is it requires to change any script include?

whenever I added else part

else {
			// If there are more than one part
			g_form.setDisplay('sw_cat_item_removed', false);
		}

 i got javascript console error

@Anish9515 

doesn't relate to script include.

try deactivating this client script and see if the exception still comes

[Anish9515]

I have noticed because of this client script only got "Java script console error" 

In Client script IF condition have only one "Software version" 

While add else condition i got console error because in else condition has multiple "software versions" separated by comma
In client script can we change into JSON format
