提交文件,jQuery.ajax给类型错误 [英] Submitting a file with jQuery.ajax gives TypeError
问题描述
我试图使用jQuery的 AJAX
方法的表单提交的文件:
I am trying to submit a file from a form using jQuery's ajax
method:
var ofile=document.getElementById('image').files[0];
var formdata = new FormData();
formdata.append("image",ofile);
$.ajax({
url:'elements/save_elements',
data:formdata,
type:'POST'
});
这导致错误类型错误:所谓的对象不实现接口FORMDATA在追加
是什么原因导致这个错误?它没有实际发生 formdata.append
,但里面的jQuery。
What causes this error? It doesn't happen on the actual formdata.append
, but inside jQuery.
推荐答案
我是有类似code同样的问题。有关于这个错误信息的严重匮乏,如此以来,OP语焉不详:
I was having the same problem with similar code. There's a severe dearth of information about this error, so since the OP didn't elaborate:
通过一些调试,我意识到正在由Ajax调用jQuery中,而不是实际的追加深处抛出的错误。
原来我忘了添加过程数据:假的contentType:假
Ajax请求;这样做解决了问题。
With some debugging I realised the error was being thrown by the ajax call in the depths of jquery, not the actual append.
Turns out I'd forgotten to add processData: false, contentType: false
to the ajax request; Doing so fixed the problem.
