我有一个.php文件,它输出一个json数据,它可以完美完成,并且我得到以下结果:
./test 1 2 3 << end
Monos(1,2)
Monos(6)
end
我还有一个.js文件,它使用XMLHttpRequest调用此结果,如下所示:
[
{
"name": "ADMINISTRATOR",
"email": "",
"first_name": "",
"last_name": ""
},
{
"name": "GUEST",
"email": "",
"first_name": "",
"last_name": ""
},
{
"name": "KRBTGT",
"email": "",
"first_name": "",
"last_name": ""
},
{
"name": "DIMERS",
"email": "",
"first_name": "Dimers",
"last_name": "David"
}
]
在控制台中,我可以获取联系人。但是我需要将响应中的值分配给调用之外的变量,就像这样
function loadDoc() {
var xhttp = new XMLHttpRequest();
xhttp.onreadystatechange = function() {
if (this.readyState == 4 && this.status == 200)
{
var contact = JSON.parse(this.responseText);
for (var i = 0; i < contact.length; i++)
{
var contacts = {name: contact[i].name, email: contact[i].email,
Govphone: contact[i].first_name, phone: contact[i].last_name};
console.log(contacts);
}
}
};
xhttp.open("GET", "js/contalist.php", true);
xhttp.send();
}
loadDoc();
有人可以帮助我至少提取联系人变量中的内容,以便在代码内的其他地方使用它吗?

您可以AsyncStorage
push
并将其在合并范围中的其他位置使用。
responseText
要获取展平的数组:
var theContacts=[];
function loadDoc() {
var xhttp = new XMLHttpRequest();
xhttp.onreadystatechange = function() {
if (this.readyState == 4 && this.status == 200) {
theContacts.push(this.responseText);
}
xhttp.open("GET", "js/contalist.php", true);
xhttp.send();
}
}
loadDoc();
.factory('ContactService', [function() {
var factory = {};
factory.getContacts = function(response) {
var contactsList=theContacts;
return contactsList;
};
return factory;
}]);

为您的factory.getContacts
使用全局函数,并且由于它是全局函数,因此可以在onreadystatechange
中使用它。
var getContacts = function(contacts) {
// do whatever you want with contacts which is array
}
// in your factory service
.factory('ContactService', [function () {
var factory = {};
factory.getContacts = getContacts;
return factory;
}]);
// in your XHR request
xhttp.onreadystatechange = function() {
if (this.readyState == 4 && this.status == 200)
{
var contact = JSON.parse(this.responseText);
var contacts = [] // init your array to store contacts
for (var i = 0; i < contact.length; i++) {
// push the contact to array
contacts.push({name: contact[i].name, email: contact[i].email, Govphone: contact[i].first_name, phone: contact[i].last_name});
}
getContacts(contacts) // call the same getContacts function
}
};
