拦截AJAX呼叫

Question

I'm currently facing problem intercepting AJAX Calls. I know how I can somehow intercept AJAX Calls at some level by ajaxSetup(). But I have one question: ajaxSetup() intercepts all calls within the document. I DON'T WANT TO DO THAT. What I'm really trying to do is changing the default type 'GET' to 'POST' of some calls. And for that I need to use ajaxSetup(). Is there any way how can I 'setup' only selected or 'ajax calls which follow a certain URL pattern'? Thank you.

Answer 1

Use beforeSend in $.ajaxSetup()

$.ajaxSetup({
    beforeSend: function (jqXhr, settings) {
        settings.type = settings.url.indexOf("foo") > -1 ? "POST" : "GET"
    }
});

GET request changed to POST -> fiddle
(check the network panel for the changed submission method)
