我想让moocher.io地理定位（{{3}}）在我的网络应用上工作。此API需要ip输入才能返回位置等。我只是尝试发送get请求以获取用户IP，因为我需要它自动查找其位置，而无需输入用户ip。
$.get("http://ipinfo.io", function(response) {
alert(response.ip);
}, "jsonp");
这将返回一个IP并提醒我IP是什么。我需要做的是把那个ip插入我的地理定位函数作为变量。这是现在完整的功能，
$(document).ready(function () {
var url = 'https://moocher-io-ip-geolocation-v1.p.mashape.com/' + ip;
var ip = $.get("http://ipinfo.io", function(response) {
alert(response.ip);
}, "jsonp");
$.ajax({
url: url
, type: 'GET'
, dataType: 'json'
, success: function (data) {
console.log('SUCCESS');
console.log(data);
console.log(data.country);
console.log(data.city);
console.log(data.state);
}
, error: function (data) {
console.log('ERROR');
console.log(data);
}
, beforeSend: setHeaders
});
});
function setHeaders(xhr) {
xhr.setRequestHeader('X-Mashape-Key',
'OURjCxSqLNmshIvDitfBhE88vFV8p1WrqCRjsnr8HkCb33A83c');
xhr.setRequestHeader('Accept', 'application/json');
}'
答案 0 :(得分：0)
现在，在您从第一个请求收到IP地址之前，正在进行第二个异步请求。只有在您收到var PaginatedDropdown = Marionette.CompositeView.extend({
template: template,
childViewOptions: {
tagName: 'li'
},
"events": function() {
'click': 'onClick',
'keyup': 'onKeyUp'
},
"onClick": function() {
return 'hello';
},
"onKeyUp": function() {
return 'hello';
},
});
var MotorcycleColorChooserDropdown = PaginatedDropdown.extend({
"events" : function() {
//Question:
//Basically extending the first events by using the marionette event function and extending it.
var parentEvents = PaginatedDropdown.prototype.events,
events = _.extend({}, parentEvents);
events['mouseenter'] = this.onMouseEnter;
//add all of the events of the child
return events;
}
"onMouseEnter": function() {
return 'vroom';
},
"onClick": function() {
//Question 2:
//Applying the parent's method
PaginatedDropdown.prototype.onClick.apply(this, arguments);
//and adding new code here
}
});
的回复后，您才会等到moocher.io发出请求。
幸运的是，这是一个快速解决方案。您可以在函数中包装第二个异步请求，并在第一个异步请求的回调中调用该函数：
ipinfo.io请注意，从$.get("https://ipinfo.io", function(response) {
alert("Initial IP address request: " + response.ip);
mooch(response.ip);
}, "jsonp");
function mooch(ip) {
var url = 'https://moocher-io-ip-geolocation-v1.p.mashape.com/' + ip;
$.ajax({
url: url
, type: 'GET'
, dataType: 'json'
, success: function (data) {
console.log('SUCCESS');
console.log(data);
console.log(data.ip.country);
console.log(data.ip.city);
console.log(data.ip.region);
}
, error: function (data) {
console.log('ERROR');
console.log(data);
}
, beforeSend: setHeaders
});
}
function setHeaders(xhr) {
xhr.setRequestHeader('X-Mashape-Key',
'OURjCxSqLNmshIvDitfBhE88vFV8p1WrqCRjsnr8HkCb33A83c');
xhr.setRequestHeader('Accept', 'application/json');
}
返回的结果数据似乎与您的初稿略有不同（它嵌套在＆＃39;密钥和＆＃39;州＆＃39; ;被列为＆＃39; region＆＃39;。
