这是我使用拖放功能动态生成的html。
<form method="POST" id="contact" name="13" class="form-horizontal wpc_contact" novalidate="novalidate" enctype="multipart/form-data">
<fieldset>
<div id="legend" class="">
<legend class="">file demoe 1</legend>
<div id="alert-message" class="alert hidden"></div>
</div>
<div class="control-group">
<!-- Text input-->
<label class="control-label" for="input01">Text input</label>
<div class="controls">
<input type="text" placeholder="placeholder" class="input-xlarge" name="name">
<p class="help-block" style="display:none;">text_input</p>
</div>
<div class="control-group"> </div>
<label class="control-label">File Button</label>
<!-- File Upload -->
<div class="controls">
<input class="input-file" id="fileInput" type="file" name="file">
</div>
</div>
<div class="control-group">
<!-- Button -->
<div class="controls">
<button class="btn btn-success">Button</button>
</div>
</div>
</fieldset>
</form>
这是我的js代码...
<script>
$('.wpc_contact').submit(function(event){
var formname = $('.wpc_contact').attr('name');
var form = $('.wpc_contact').serialize();
var FormData = new FormData($(form)[1]);
$.ajax({
url : '<?php echo plugins_url(); ?>'+'/wpc-contact-form/resources/js/tinymce.php',
data : {form:form,formname:formname,ipadd:ipadd,FormData:FormData},
type : 'POST',
processData: false,
contentType: false,
success : function(data){
alert(data);
}
});
}

要获得正确的表单数据使用,您需要执行2个步骤。
<强>制剂强>
您可以将整个表单提供给FormData()进行处理
var form = $('form')[0]; // You need to use standard javascript object here
var formData = new FormData(form);
或指定FormData()
的确切数据var formData = new FormData();
formData.append('section', 'general');
formData.append('action', 'previewImg');
// Attach file
formData.append('image', $('input[type=file]')[0].files[0]);
发送表单
使用jquery的Ajax请求将如下所示:
$.ajax({
url: 'Your url here',
data: formData,
type: 'POST',
contentType: false, // NEEDED, DON'T OMIT THIS (requires jQuery 1.6+)
processData: false, // NEEDED, DON'T OMIT THIS
// ... Other options like success and etc
});
在此之后,它将发送ajax请求,就像您使用enctype="multipart/form-data"
更新:如果没有type:"POST"
选项,此请求将无法运行,因为所有文件都必须通过POST请求发送。
注意: contentType: false
仅提供from jQuery 1.6 onwards

我无法在上面添加评论,因为我没有足够的声誉,但上述答案对我来说几乎是完美的,除了我必须添加
输入:“POST”
到.ajax电话。我试着弄清楚自己做错了什么,这是我所需要的一切,并且是一种享受。所以这就是整个片段:
完全赞同我上面的答案,这只是一个小小的调整。这是为了防止其他人被卡住,看不到明显的问题。
$.ajax({
url: 'Your url here',
data: formData,
type: "POST", //ADDED THIS LINE
// THIS MUST BE DONE FOR FILE UPLOADING
contentType: false,
processData: false,
// ... Other options like success and etc
})

更好地使用本机javascript通过ID查找元素,例如: document.getElementById(“ yourFormElementID”) 。
$.ajax( {
url: "http://yourlocationtopost/",
type: 'POST',
data: new FormData(document.getElementById("yourFormElementID")),
processData: false,
contentType: false
} ).done(function(d) {
console.log('done');
});

if (files.length != 0) {
var data = new FormData();
for (var i = 0; i < files.length ; i++) {

}
$.ajax({
xhr: function () {
var xhr = $.ajaxSettings.xhr();

实际上文档显示您可以使用XMLHttpRequest().send()
简单地发送多形式数据
如果jquery糟透了

早上好。
我在上传多张图片时遇到了同样的问题。解决方案比我想象的要简单:在名称字段中包含[]。
<input type="file" name="files[]" multiple>
我没有对FormData进行任何修改。
