Implement button gray countdown in the success callback function of jquery ajax_jquery

The main purpose is to realize that after the asynchronous mobile phone successfully sends a text message, the send button is grayed out and counts down in the success callback of ajax. At the beginning, a js error is reported all the time. The problem may be that this is updated after calling ajax. Feel free to change the this object before doing so. Assigning it to a variable is no problem

Button countdown code

Copy code The code is as follows:

var wait = 60;
get_code_time = function (o) {
if (wait == 0) {
o.removeAttribute("disabled");
o.value = " Get the verification code for free";
wait = 60;
} else {
o.setAttribute("disabled", true);
o.value = "(" wait ") and get it again after seconds ";
wait--;
setTimeout(function() {
get_code_time(o)
}, 1000)
}
}

get After the mobile phone text message, call the get_code_time function code

Copy the code The code is as follows:

//Re-obtain verification Code
$('#codeagain').click(function() {
var o = this;
$.ajax({
url:"Tea_sendCode.action?jsoncallback=?",
type: "post",
data: {accountId:accountId},
dataType: "json",
success: function (data) {
if(data.status == 1 && data.code == 200){
alert("Verification code has been sent to your mobile phone");
get_code_time(o);
} else {

if(data.msg != ""){
alert(data.msg);
} else {
alert("Failed to send SMS verification code");
}
}
},
error: function (data) {
if(data.status == 0) {
alert(data.msg);
} else {
alert("Failed to send SMS verification code" );
}
}
});
});
