当我成功登录时,我希望它重定向到没有重新加载的页面
只要要重定向到的页面位于同一个域中,或者您可以正确设置CORS标头,并且可以处理相对链接,那么在成功回调中,您可以将整个页面的HTML替换为新的一页。
您可以为新页面启动另一个ajax调用,并使用document.write()
删除现有HTML,如下所示:
...
success: function(html){
if(html=='1') {
$("#login_form").fadeOut("normal");
$("#shadow").fadeOut(400, function(){
// Completely replace the page's HTML
$.ajax({
type: 'GET',
url: 'http://example.com/logged-in',
async: false, // You want this synchronous
success: function(data) {
// This code block replaces your current page seamlessly
document.open();
document.write(data);
document.close();
},
error: function(e){
alert(e.message);
}
});
});
}
...
这是一个演示:
$("#bye").fadeOut(1400, function(){
$.ajax({
type: 'GET',
url: 'http://enable-cors.org/',
async: false,
success: function(data) {
// This is a quick-n-dirty hack
// to get the relative links working for the demo
var base_href = '<base href="http://enable-cors.org/">';
document.open();
document.write(base_href + data);
document.close();
},
error: function(e){
alert(e.message);
}
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<div id="bye"><h1>Logged in Successfully</h1></div>
