[英]How can I get files by javascript and post send for ajax
I have this form in html for multiple file uploading . 我在html中有这个表单用于多个文件上传。
<form class="userform" method="post" action="upload.php" role="form" enctype="multipart/form-data" >
<input name="title" type="text" ><br/>
<input type="file" name="media[]" >
<div class="filesupload">
<input type="file" name="media[]" >
</div>
<script>
$(document).on("click",".add-new-file",function()
{
$('.filesupload').append('<input name="media[]" type="file" >');
});
</script>
</form>
I will get input files by javascript and send to upload.php for uploading. 我将通过javascript获取输入文件并发送到upload.php进行上传。 but I don't know how to get files values in javascript.
但我不知道如何在javascript中获取文件值。
If you using HTML5 如果您使用HTML5
var fileList = document.getElementById("yourInput").files;
for(var i = 0; i < fileList.length; i++) {
//Do something with individual files
}
Using jquery 使用jquery
$("input[name=file1]").change(function() {
var names = [];
for (var i = 0; i < $(this).get(0).files.length; ++i) {
names.push($(this).get(0).files[i].name);
}
$("input[name=file]").val(names);
});
