Facebook登录onClick - Javascript [英] Facebook login onClick - Javascript
问题描述
< script>
//其他JS函数
window.fbAsyncInit = function(){
FB.init({
appId:'xxxxxxxxxxxxxx',// App ID
channelUrl :'//192.168.1.127/test/channel.html',// Channel File
status:true,//检查登录状态
cookie:true,//启用Cookie以允许服务器访问会话
xfbml:true //解析XFBML
});
//其他初始化代码在这里
FB.getLoginStatus(function(response){
if(response.status ==='connected'){
//连接
} else if(response.status ==='not_authorized'){
// not_authorized
login();
} else {
// not_logged_in
login();
}
});
};
函数login(){
FB.login(function(response){
if(response.authResponse){
testAPI();
}否则{
//取消
}
});
}
function testAPI(){
console.log('Welcome!Fetching your information ....');
FB.api('/ me',function(response){
console.log('Good to see you,'+ response.name +'。');
});
}
//异步加载SDK
(function(d){
var js,id ='facebook-jssdk',ref = d.getElementsByTagName 'script')[0];
if(d.getElementById(id)){return;}
js = d.createElement('script'); js.id = id; js.async = true;
js.src =//connect.facebook.net/en_US/all.js;
ref.parentNode.insertBefore(js,ref);
}(document)) ;
< / script>
我想要 FB.getLoginStatus
事件每当用户点击这个时,都要点燃:
< a href =#onClick =FB.getLoginStatus() >登录< / A>
但是现在正在加载,没有我做任何事情。
建议?
确定这里有一个简单的解决方案 - 将调用包含在另一个函数中的 FB.getLoginStatus
中,并让您的按钮调用 功能。
function doLogin(){
FB.getLoginStatus(function(response){
...
};
}
然后,您可以更改按钮上的 onClick
到 doLogin()
。
Bassicaly,这里发生的是,一旦加载了Facebook SDK,它调用包含您的 FB.getLoginStatus
代码的 window.fbAsyncInit
函数,所以一旦SDK准备就绪,登录代码正在执行。
I have this code on my website. The facebook login dialog is being shown when my page has loaded and not when the user has click on an anchor tag.
<script>
// Additional JS functions here
window.fbAsyncInit = function() {
FB.init({
appId : 'xxxxxxxxxxxxxx', // App ID
channelUrl : '//192.168.1.127/test/channel.html', // Channel File
status : true, // check login status
cookie : true, // enable cookies to allow the server to access the session
xfbml : true // parse XFBML
});
// Additional init code here
FB.getLoginStatus(function(response) {
if (response.status === 'connected') {
// connected
} else if (response.status === 'not_authorized') {
// not_authorized
login();
} else {
// not_logged_in
login();
}
});
};
function login() {
FB.login(function(response) {
if (response.authResponse) {
testAPI() ;
} else {
// cancelled
}
});
}
function testAPI() {
console.log('Welcome! Fetching your information.... ');
FB.api('/me', function(response) {
console.log('Good to see you, ' + response.name + '.');
});
}
// Load the SDK Asynchronously
(function(d){
var js, id = 'facebook-jssdk', ref = d.getElementsByTagName('script')[0];
if (d.getElementById(id)) {return;}
js = d.createElement('script'); js.id = id; js.async = true;
js.src = "//connect.facebook.net/en_US/all.js";
ref.parentNode.insertBefore(js, ref);
}(document));
</script>
I want the FB.getLoginStatus
event to be fired up whenever the user click on this:
<a href = "#" onClick = "FB.getLoginStatus()">Login</a>
But right now it's being loaded without me doing anythings.
Suggestions?
Ok so there is a simple solution here - wrap the call to FB.getLoginStatus
in another function and have your button call that function.
function doLogin(){
FB.getLoginStatus(function(response) {
...
};
}
Then you can change the onClick
on your button to doLogin()
.
Bassicaly, what was happening here is that as soon as the Facebook SDK is loaded, it calls the window.fbAsyncInit
function which contained your FB.getLoginStatus
code, so as soon as the SDK was ready, the login code was being executed.
