我正在使用ajax successives请求,我需要在所有成功请求完成后进行回调
u
使用此代码,在调用" exemple2.php"之前调用done函数。成功了。
我怎么能等待呢?
感谢您的回答!

function doAjaxRequest(data, id) {
// Get payment Token
return new Promise(function(resolve,reject){
$.ajax({
type: "POST",
url: 'exemple1.php',
data: data
success: function(msg){
$.ajax({
type: "POST",
url: 'exemple2.php',
data: msg,
success: function(msgr) {
document.getElementById(id).value=msgr;
resolve();
},
error:function (xhr, status, error) {
//Do something
reject();
}
});
},
error:function (xhr, status, error) {
//Do something
reject();
}
});
});
}
Promise.all([
doAjaxRequest(data, "input-1"),
doAjaxRequest(otherData, "input-2")])
.then(function(values){
//Need do something when both second ajax requests (example2.php) are finished
}

你的sub ajax请求独立于第一个ajax结果,然后对example2的调用与$ .when()promise.abort完全分开 只是尝试使用jquery $ .ajax返回promise这样的事实 这是我的代码来自plnkr
// Code goes here
function doAjaxRequest(data, id) {
// Get payment Token
return $.ajax({
type: "GET",
url: 'example1.json',
data: data
}).then(function(msg, status, jqXhr) {
return $.ajax({
type: "GET",
url: 'example2.json',
data: msg
});
}).done(function(msgr) {
console.log(msgr);
return msgr;
});
}
var data = {foo:'bar'};
var otherData = {foo2:'bar2'};
$.when(
doAjaxRequest(data, "input-1"),
doAjaxRequest(otherData, "input-2")
).done(function(a1, a2) {
console.log(a1, a2);
//Need do something when both second ajax requests (example2.php) are finished
});
注意,我用GET替换POST并在plnkr上使用exampleX.json

返回自定义延迟对象,例如:
function doAjaxRequest(data, id) {
var d = new $.Deferred();
// Get payment Token
$.ajax({
type: "POST",
url: 'exemple1.php',
data: data
success: function(msg){
$.ajax({
type: "POST",
url: 'exemple2.php',
data: msg,
success: function(msgr) {
document.getElementById(id).value=msgr;
d.resolveWith(null, [msgr]); // or maybe d.resolveWith(null, [msg]);
},
error:function (xhr, status, error) {
//Do something
d.reject();
}
});
},
error:function (xhr, status, error) {
//Do something
d.reject();
}
});
return d;
}
现在,我不确定您传递给$.when().done()
回调的预期数据是什么。
