我的$ ajax通话无效

Question

When executing the following code:

url= "http://192.168.2.171/LoginAuthentication";
$.ajax({
    url: 'url',
    type: 'GET',
    success: function(res) {
        var headline = $(res.responseText).find('a.tsh').text();
        alert(headline);
    }
});

I get this error:

Object XMLHttpRequest cannot load 'url'. Origin null is not allowed by Access-Control-Allow-Origin.

Answer 1

url="http://192.168.2.171/LoginAuthentication";
$.ajax({
    url: url,
    type: 'GET',
    success: function(res) {
        var headline = $(res.responseText).find('a.tsh').text();
        alert(headline);
    }
});

But it may not work if you are not making a request to the same domain
