是否可以在ajax调用中将函数传递给url字段？

Question

Is it possible to pass a function to the url field in an ajax call? I want to dynamically pass a different url to the ajax call made.

function getMeURL(){}

$.ajax({
  url: getMeURL,
  context: document.body,
  success: function(){
    $(this).addClass("done");
  }
});

Answer 1

您不应该传递函数，但是可以传递函数的返回值。

url: GetMeUrl(args)

Answer 2

use ()

function getMeURL(){}

$.ajax({
  url: getMeURL(),
  context: document.body,
  success: function(){
    $(this).addClass("done");
  }
});

Answer 3

You can pass the result of a function, but not a function itself as you seem to be trying to do. Here's an updated example (notice the parentheses):

function getMeURL() {
    return "http://www.example.com";
}
$.ajax({
  url: getMeURL(),
  context: document.body,
  success: function(){
    $(this).addClass("done");
  }
});
