我需要知道如何删除上传的图像或删除输入隐藏的值。
例如,进入if(document.getElementByID(“eliminar”)。click())。
非常感谢。
<script type="text/javascript" >
$(function(){
var btnUpload=$('#upload');
var status=$('#status');
new AjaxUpload(btnUpload, {
action: 'upload-file.php',
name: 'uploadfile',
nSubmit: function(file, ext){
if(!(ext && /^(jpg|png|jpeg|gif)$/.test(ext))){
// extension is not allowed
status.text('Only JPG, PNG or GIF files are allowed');
return false;
}
//status.text('Uploading...');
status.show();
},
onComplete: function(file, response){
//On completion clear the status
status.text('');
//Add uploaded file to list
if(response==="success"){
$('<li></li>').appendTo('#files').html('<img src="./uploads/'+file+'"/><input type="hidden" name="uploadfile[]" value="'+file+'"><button name="eliminar" id="eliminar">Eliminar</button>').addClass('success');
if(document.getElementById("eliminar").click()){
}
} else{
$('<li></li>').appendTo('#files').text(file).addClass('error');
}
}
});
});
</script>
那是我的upload-file.php
<?php
$uploaddir = './uploads/';
$file = $uploaddir . basename($_FILES['uploadfile']['name']);
if (move_uploaded_file($_FILES['uploadfile']['tmp_name'], $file)) {
echo "success";
} else {
echo "error";
}
?>

unlink
用于删除php中服务器上的文件
unlink("./uploads/filename");
发送了ajax请求并取消链接文件
function removeFile(){
$.ajax({
url:'fileDel.php',
data:'fllename',
dataType:'json',
success:function(){
alert("file deleted");
}
});
}
