Question

我的问题是我不知道如何使用下面的代码发送输入文本值。

我在某个网站上找到了这段代码，但我不知道如何用它发送输入文本值，因为它只发送文件。

<script>

/* Video Tutorial: http://www.youtube.com/watch?v=EraNFJiY0Eg */
function _(el){
    return document.getElementById(el);
}
function uploadFile(){
    var file = _("file1").files[0];
    var name = _("name").value;
    // alert(file.name+" | "+file.size+" | "+file.type);
    var formdata = new FormData();
    formdata.append("file1", file);
    formdata.append("name", file);
    var ajax = new XMLHttpRequest();
    ajax.upload.addEventListener("progress", progressHandler, false);
    ajax.addEventListener("load", completeHandler, false);
    ajax.addEventListener("error", errorHandler, false);
    ajax.addEventListener("abort", abortHandler, false);
    ajax.open("POST", "file_upload_parser.php");
    ajax.send(formdata);
}
function progressHandler(event){
    _("loaded_n_total").innerHTML = "Uploaded "+event.loaded+" bytes of "+event.total;
    var percent = (event.loaded / event.total) * 100;
    _("progressBar").value = Math.round(percent);
    _("status").innerHTML = Math.round(percent)+"% uploaded... please wait";
}
function completeHandler(event){
    _("status").innerHTML = event.target.responseText;
    _("progressBar").value = 0;
}
function errorHandler(event){
    _("status").innerHTML = "Upload Failed";
}
function abortHandler(event){
    _("status").innerHTML = "Upload Aborted";
}
</script>
</head>

这个php代码：

<?php
$fileName = $_FILES["file1"]["name"]; // The file name
$fileTmpLoc = $_FILES["file1"]["tmp_name"]; // File in the PHP tmp folder
$fileType = $_FILES["file1"]["type"]; // The type of file it is
$fileSize = $_FILES["file1"]["size"]; // File size in bytes
$fileErrorMsg = $_FILES["file1"]["error"]; // 0 for false... and 1 for true
$name = $_POST['name'];
if (!$fileTmpLoc) { // if file not chosen
    echo "ERROR: Please browse for a file before clicking the upload button.";
    exit();
}
if(move_uploaded_file($fileTmpLoc, "$fileName")){
    echo "$fileName upload is complete $name";
} else {
    echo "move_uploaded_file function failed";
}
?>

请编辑我的代码帮助我，谢谢。

Answer 1

您只需要更改代码

编辑JS FROM

var formdata = new FormData();
formdata.append("file1", file);
formdata.append("name", file); // IMPORTANT : FROM THIS

编辑JS TO

var formdata = new FormData();
formdata.append("file1", file);
formdata.append("name", name); // IMPORTANT : TO THIS

在您的completeHandler（）中运行一个单独的函数，该函数会在您的图片上传后通过ajax上传文本数据。
