我有这个表格：
<form id="imageinputpopup" class=suggestionsubmit style="display: none">
<span>Add a thing!</span><br/>
<label>url: </label><input name="imageurl" type="url"><br/>
<label>file: </label><input name="imagefile" type="file"><br/>
<input type='hidden' name='schoolid' class="schoolid">
<input type="submit" value="Submit">
</form>
而这个文件。准备好了：
<script type="text/javascript">
$(document).ready(function() {
$('.schoolid').val(get_gmap_value('school_id'));
$(".allow-submission").live('click', function(){
if($(this).attr('inputtype')=="colorpicker"){
.....
} else if($(this).attr('inputtype')=="image"){
remove_hidden("#imageinputpopup");
add_fieldname($(this), $("#imageinputpopup"));
$("#imageinputpopup").dialog();
} else if($(this).attr('inputtype')=="text"){
....
} else {
//nothing
}
});
$(".suggestionsubmit").submit(function(){
event.preventDefault();
alert($(this).html());
$(this).ajaxSubmit({
url: '/save-school-suggestion/',
type: 'post',
success: function(response){
response = jQuery.parseJSON(response);
// Check for login redirect.
// if ( response.requireLogin ) {
// alert('Sign up or log in to save your answer');
// } else {
$('.suggestionsubmit').dialog('close');
// }
}
});
});
});
function add_fieldname(element, addto){
var elementname = document.createElement('input');
elementname.type = 'hidden';
elementname.name = 'fieldname';
elementname.value = element.attr('fieldname').replace(' ', '_');
$(elementname).addClass('fieldname');
addto.append(elementname);
}
function remove_hidden(element){
$(element+' .fieldname').remove();
}
但是文件字段没有显示在服务器端。
为什么？
我在文档中找到了这个：
为什么没有发布我的所有输入值？jQuery 表单序列化与 HTML 规范密切相关。只有成功的控件才能提交。
但我不明白为什么我的文件控制无效。我在我的网站的不同位置有另一个提交表单，几乎相同并且运行良好......
编辑：这是另一种有效的表单（它有一些额外的东西，但表单标签只有一个 id，就像问题一样，输入标签是相同的）。
