Async false表示速记AJAX获取请求

I am using the following ajax get function to check the status of a user. Is it possible to set async: false with this shorthand method? If not how can this be changed so that I can add async false?

我使用以下ajax get函数来检查用户的状态。是否可以使用此简写方法设置async:false?如果不是如何更改,以便我可以添加async false?

$.get("/submit/checkuser/", function (userStatus) {
    if (userStatus == 'Disabled') { // check if user if disabled                    

    } else if (userStatus == 'Deleted') { // check if user if deleted

    } else {

    };
}).fail(function () {                
    connectionError();
});

This might work for you

这可能对你有用

$.ajax({
    url : "/submit/checkuser/",
    type : "get",
    async: false,
    success : function(userStatus) {
       if (userStatus == 'Disabled') { // check if user if disabled                    
       } else if (userStatus == 'Deleted') { // check if user if deleted
       } else {
       };
    },
    error: function() {
       connectionError();
    }
 });

The only way to make a synchronous $.get call is to set ajaxSetup to synchronous:

进行同步$ .get调用的唯一方法是将ajaxSetup设置为synchronous:

jQuery.ajaxSetup({async:false});

This is considered bad form though, since it affects every ajax call made by JQuery on the page. I would suggest just biting the bullet and using the more elaborate jQuery.ajax syntax.

这被认为是不好的形式,因为它会影响JQuery在页面上发出的每个ajax调用。我建议只是咬紧牙关并使用更精细的jQuery.ajax语法。

See How can I get jQuery to perform a synchronous, rather than asynchronous, Ajax request? for a fuller discussion.

请参阅如何让jQuery执行同步而非异步的Ajax请求?进行更全面的讨论。

From above though, I use it like this

从上面来看,我这样使用它

jQuery.ajaxSetup({async:false});

  // my code 

jQuery.ajaxSetup({async:true});

#4

Try this.

$.get('/your/url/dot/com', { async: false }, function(data){
    globalBaseURL = data;
});

#5

Use jQuery.ajaxSetup({async:false}); because $.get() is Jquery shorthand method with syntax jQuery.get( url [, data ] [, success ] [, dataType ] ) and to make changes to setting there is jQuery.get( [settings ] )

使用jQuery.ajaxSetup({async:false});因为$ .get()是Jquery的简写方法,语法为jQuery.get(url [,data] [,success] [,dataType])并且对设置进行更改时有jQuery.get([settings])
