ajax请求方式

$.ajax({
url: "/add_host_ajax",
type: ‘POST‘,
contentType: "application/x-www-form-urlencoded; charset=UTF-8",
data: $("#add_form").serialize(),
success: function (data) {
var obj = JSON.parse(data);
if (obj.status) {
location.reload();
} else {
$(‘#erro_msg2‘).text(obj.error);
}
}
})

2.拼接url的ajax
$.ajax({
url: "/add_host_ajax?hostname="+hostname1111,
success: function (data) {
var obj = JSON.parse(data);
if (obj.status) {
location.reload();
} else {
$(‘#erro_msg2‘).text(obj.error);
}
}
})

3.拼data的ajax$.ajax({url: "/add_host_ajax?hostname="+hostname1111,type: ‘POST‘,contentType: "application/x-www-form-urlencoded; charset=UTF-8",data: ‘hostname=‘+hostname1111,success: function (data) {var obj = JSON.parse(data);if (obj.status) {location.reload();} else {$(‘#erro_msg2‘).text(obj.error);}}})
