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); }); }
