i have onRequestEnd Method and have some javascript code in that, that is basically breaking all ajaxc alls of my page, how can i fix that

You can do a check to not include if the request is an

XMLHttpRequest

by looking for this value in the

["X-Requested-With"]

header. If you are using fetch in the JS side, then this useful header is not included but you can add headers to your fetch calls. I tend to add it and just add the word fetch. Here is a function I have that I use in many places. Place it in your Application.cfc and then you can use it wherever you want in it or within your views. But I too recommend that you do not try to inject stuff @

onRequestEnd()

especially if you are not inspecting the output and then re-injecting before your body close tag to retain proper structure.

public boolean function isAjax(){
		var req = getHttpRequestData().headers;
		return structKeyExists(req,"X-Requested-With") && listFindNoCase("fetch,XMLHttpRequest",req["X-Requested-With"]) ? true : false;
}

Yeah,

X-Requested-With

is not a standard HTTP header but quite a few Javascript libraries do set it for you (like jQuery) so may already be there.

But I am not using fetch I am using ruthe Ajax or post or get in the Ajax call

What are you using to make you AJAX request? Like @aliaspooryorik stated, if you are using jQuery, that header is included and if not, it should be fairly easy to add a header to your request if just using vanilla JavaScript.

is a legacy app with mix and match of jquery adn javascript

Then that means you are most likely using jQuery for Ajax requests, so go ahead and try using that function to omit your JS that you add at onRequestEnd.

ok
