废话不多说了，具体实现代码如下所示：
<!DOCTYPE html>
<html>
<head lang="en">
<meta charset="UTF-8">
<title></title>
<script src="./jquery-1.9.1.min.js"></script>
</head>
<body>
<form id= "uploadForm" action= "" method= "post" enctype ="multipart/form-data">
<h1 >多文件上传 </h1>
<table>
<tr>
<td >上传文件： <input type ="file" name="file[]" id="file" multiple="multiple"/><a href="javascript:;" id="add">[+]</a></td>
</tr>
<tr>
<td>
<input type ="button" value="上传" id="but"/>
</td>
</tr>
</table>
</form>
</body>
</html>
<script>
//添加
$(document).on("click","#add",function(){
var str_tr = "<tr>"+$(this).parents("tr").html()+"</tr>";
//js 替换字符串样式
str_tr = str_tr.replace(/\+/,'-');
var new_str_tr = str_tr.replace(/add/,'del');
$(this).parents("tr").after(new_str_tr);
})
//删除
$(document).on("click","#del",function(){
$(this).parents("tr").remove();
})
//文件上传
$("#but").click(function(){
var formData = new FormData($( "#uploadForm" )[0]);
$.ajax({
url: 'http://localhost/demo/selfWork_MVC/easymvc/app/Views/Index/upload.php' ,
type: 'POST',
data: formData,
async: false,
cache: false,
contentType: false,
processData: false,
success: function (returndata) {
alert(returndata);
},
error: function (returndata) {
alert(returndata);
}
});
})
</script>
