How to send additional data to jQuery File Upload Plugin?
提问by eric.itzhak
This would seem stupid but i can't seem to understand the documentation. I'm talking about Thisplugin for file upload.
这看起来很愚蠢，但我似乎无法理解文档。我说的是这个用于文件上传的插件。
Now according to the documentation there's an option :
现在根据文档有一个选项：
formData
Additional form data to be sent along with the file uploads can be set using this option, which accepts an array of objects with name and value properties, a function returning such an array, a FormData object (for XHR file uploads), or a simple object. The form of the first fileInput is given as parameter to the function.
Note: Additional form data is ignored when the multipart option is set to false.
Type: Array, Object, function or FormData Default: A function returning the form fields as serialized Array:
function (form) { return form.serializeArray(); }Example:
[ { name: 'a', value: 1 }, { name: 'b', value: 2 } ]
表单数据
可以使用此选项设置要与文件上传一起发送的其他表单数据，该选项接受具有名称和值属性的对象数组、返回此类数组的函数、FormData 对象（用于 XHR 文件上传）或简单的目的。第一个 fileInput 的形式作为函数的参数给出。
注意：当 multipart 选项设置为 false 时，附加表单数据将被忽略。
类型：数组、对象、函数或 FormData 默认值：将表单字段作为序列化数组返回的函数：
function (form) { return form.serializeArray(); }例子：
[ {名称：'a'，值：1}，{名称：'b'，值：2}]
Which i fail to understand what i'm suppoused to do with that.
我不明白我应该用它做什么。
This is how i initialize the plugin :
这就是我初始化插件的方式：
$('#add_image_upload').fileupload({
dataType: 'json',
sequentialUploads: true,
formData : getDate
});
And this is my attempt to the function :
这是我对功能的尝试：
function getDate(){
//if user didn't selected a date
if(!selectedDate || selectedDate=="undefined"){
selectedDate = "1/1/"+$('#timeline').html();
}
var date= new Array(selectedDate);
return date;
}

try turning your data into in object - with what they showed in their example
尝试将您的数据转换为对象 - 使用他们在示例中显示的内容
$('#add_image_upload').fileupload({
dataType: 'json',
sequentialUploads: true,
formData : {name:'thedate',value:getDate}
});
Then to add more params
然后添加更多参数
//name of param // value
formData : [{name:'thedate',value:getDate},{name:'thedate2',value:'seconddate'},etc..]
Example:
[ { name: 'a', value: 1 }, { name: 'b', value: 2 } ]
例子：
[ {名称：'a'，值：1}，{名称：'b'，值：2}]
Changing thedatewith whatever you want to name the param
更改thedate您想要命名参数的任何内容
Though it sounds like a simple object should work fine
虽然听起来像一个简单的对象应该可以正常工作
//name:value
formData : {thedate:getDate}

Do you have multipartset to falseon your form? Also, ensure the format of what you're sending back is acceptable.
你的表格上有multipart设置false吗？此外，请确保您发回的格式是可以接受的。
Try hard-coding the following line and sending back the info:
尝试对以下行进行硬编码并发回信息：
new dateobject = { "date": "1/1/2012" }
