在有文件上传的表单提交过程中，搞不好就会报Posted content type isn't multipart/form-data的错误。
解决办法
<form class="form-horizontal" action="${ctx}/project/addProjectReback?callbackType=closeCurrent"
enctype="multipart/form-data" method="post" οnsubmit="return iframeCallback(this, dialogAjaxDone)">
<input type="file" name="image" class="required" accept="image/gif, image/jpeg, image.png">
-
enctype="multipart/form-data"必须有这段代码。 - 必须对该上传文件类型的表单进行封装，区分普通的表单上传。
/**
* 带文件上传的ajax表单提交
*
* @param {Object}
* form
* @param {Object}
* callback
*/
function iframeCallback(form, callback) {
YUNM.debug("带文件上传处理");
var $form = $(form), $iframe = $("#callbackframe");
// 富文本编辑器
$("div.editor", $form).each(
function() {
var $this = $(this);
var editor = "<input type='hidden' name='" + $this.attr("name") + "' value='"
+ $.base64.btoa($this.html()) + "' />";
$form.append(editor);
});
var data = $form.data('bootstrapValidator');
if (data) {
if (!data.isValid()) {
return false;
}
}
if ($iframe.size() == 0) {
$iframe = $("<iframe id='callbackframe' name='callbackframe' src='about:blank' style='display:none'></iframe>")
.appendTo("body");
}
if (!form.ajax) {
$form.append('<input type="hidden" name="ajax" value="1" />');
}
form.target = "callbackframe";
_iframeResponse($iframe[0], callback || YUNM.ajaxDone);
}
function _iframeResponse(iframe, callback) {
var $iframe = $(iframe), $document = $(document);
$document.trigger("ajaxStart");
$iframe.bind("load", function(event) {
$iframe.unbind("load");
$document.trigger("ajaxStop");
if (iframe.src == "javascript:'%3Chtml%3E%3C/html%3E';" || // For
// Safari
iframe.src == "javascript:'<html></html>';") { // For FF, IE
return;
}
var doc = iframe.contentDocument || iframe.document;
// fixing Opera 9.26,10.00
if (doc.readyState && doc.readyState != 'complete')
return;
// fixing Opera 9.64
if (doc.body && doc.body.innerHTML == "false")
return;
var response;
if (doc.XMLDocument) {
// response is a xml document Internet Explorer property
response = doc.XMLDocument;
} else if (doc.body) {
try {
response = $iframe.contents().find("body").text();
response = jQuery.parseJSON(response);
} catch (e) { // response is html document or plain text
response = doc.body.innerHTML;
}
} else {
// response is a xml document
response = doc;
}
callback(response);
});
}
