[英]How to get param in form
My html 我的HTML
<form action="/csv/load" enctype="multipart/form-data" id="csv_upload_form" method="post" style="margin: 10px 0;">
<input type="file" id="upload_file" name="upload_file" />
<span><input type="submit" value="Upload File" /></span>
</form>
~~
<input type="button" name="send" id="send" value="send">
In my case, I do not want to put button send in form. 就我而言,我不想在表单中放置按钮发送。 Can I get param upload_file when click button send by jquery?
单击jquery发送的单击按钮时能否获取param upload_file?
My jquery does not work: 我的jQuery不起作用:
$("#send" ).click(function() {
var formData = new FormData($('form#csv_upload_form')[0]);
// formData = $('#csv_upload_form').find(':input').serializeArray() --> formData is empty
$.ajax({
url: "/csv/register",
type: "post",
dataType: 'json',
data: formData,
success: function(response) {
..something
}
});
formData if empty formData如果为空

jQuery by default tries to make it a string, you need to turn this feature off and set the content type as well jQuery默认尝试将其设置为字符串,您需要关闭此功能并设置内容类型
$.ajax({
url: "/csv/register",
type: "post",
contentType: false,
processData: false,
data: formData,
success: function(response) {
..something
}
});
