Jquery的跨域问题

Question

I am trying to create a chrome extension which will look up the meaning of input vocabulary from this URL: http://hanviet.org/ajax.php?query=%E6%97%A5&methode=normal

I made an ajax call by using jquery but got an error because of the cross-domain issue: "No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'null' is therefore not allowed access". Ok, I guest that instead of make a request directly to the URL, I need to call it through a proxy pages as below:

$.get("/myproxy.php?query=日&methode=normal", function( data ) {
    alert( "Load was performed." );
});

After doing a google search, there is another chrome extension named DHC to makes http request: https://www.sprintapi.com/dhcs.html. and It works perfectly!

I am wondering that does DHC tool also send a request through its proxy or there is another way to make a direct request that I dont know.

Thank you!

Answer 1

If you use the developers tools of chrome on that site, on Network tab you will see that after pressing the sendbutton it loads the content from https://www.sprintapi.com/api/proxy, so yes, it should be using a proxy.

Even more, as you say the Access-Control-Allow-Origin would'nt let they did it on another way I think.
