如何将formdata对象发布到ajax post调用? [英] How to post a formdata object into ajax post call ?
问题描述
我有一个formdata对象如何使用ajax帖子发布它?我试过这样的方式:
但是当我在浏览器中运行它时,它会启动一个无限循环,不知道为什么
var formData = {name: ravi,年龄: 31}; // 数组
$ .ajax({
url: ./ Index,
type: POST,
data:formData,
success: function (data,textStatus,jqXHR){
$( #div3)。html(数据);
// 数据 - 来自服务器的响应
},
错误: function (jqXHR,textStatus,errorThrown){
}
} );
我的尝试:

因为将变量命名为formData不会使其成为formdata对象。以下是否为新的整数值?
var integer = ' Afzaal Ahmad Zeeshan';
不,你也这样做,你需要的是使用FormData
对象;不是一个普通的JavaScript对象。我写了一篇涵盖这个主题的文章,请仔细阅读,上传文件 - HTML5和jQuery Way! [ ^ ]
您需要的是一个HTML表单,然后您可以创建一个新的FormData
来自它的对象并将其上传到服务器,示例,
< < span class =code-leadattribute> form method = 发布 id = formid >
<! - 这里控制。 - >
< / form >
那么JavaScript就是,
var formData = new FormData(
i have a formdata object how do i post it using ajax post ? I tried it this way:
but when i run it in the browser , it will just start an infinite loop, not sure why
var formData = { name: "ravi", age: "31" }; //Array
$.ajax({
url: "./Index ",
type: "POST",
data: formData,
success: function (data, textStatus, jqXHR) {
$("#div3").html(data);
//data - response from server
},
error: function (jqXHR, textStatus, errorThrown) {
}
});

Because naming a variable as formData doesn't make it a formdata object. Does the following make a new integer value?
var integer = 'Afzaal Ahmad Zeeshan';
No. You're doing the same, what you need is to useFormData
object; not a plain JavaScript object. I wrote an article that covers this topic, kindly read it, Uploading the Files – HTML5 and jQuery Way![^]
What you need is an HTML form, then you can create a newFormData
object from it and upload it to server, sample,
<form method="post" id="formid"> <!-- Controls here. --> </form>
Then the JavaScript would be,
var formData = new FormData(
