$.ajax({
success: function (returns) {
if (returns)
alert("returned successfully");
}
});
如何将这个jquery函数转换为纯js?顺便说一句,我是js新手!
在XMLHttpRequest对象上添加onreadystatechange
:上的侦听器
xhr.onreadystatechange = function() {
if (xhr.readyState == 4 && (xhr.status == 200 || xhr.status == 0)) {
option.success(xhr.responseText)
}
}
