我正在使用 FormData 上傳文件，如下所示<script>var form = document.forms.namedItem("excelForm");form.addEventListener('submit', function(ev) { oData = new FormData(form);oData.append("CustomField", "This is some extra data");var oReq = new XMLHttpRequest();oReq.open("POST", "excel", true);oReq.onload = function(oEvent) { if (oReq.status == 200) { $("#downloadButton").attr("style", "visibility: visible;") alert(oReq.response) } else { alert(oReq.status) } }; oReq.send(oData); ev.preventDefault();}, false);</script>這將調(diào)用一個 php 函數(shù)，該函數(shù)將返回一個 vlue，所以我想捕獲該值，我使用 oReq.response 來捕獲該返回值，但它不起作用這是我的 php 函數(shù) public function actionexcel() { //......... if (move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $target_file)) {// re write the excel file $fileName =$date. basename($_FILES["fileToUpload"]["name"]); $newFile = $this->RewriteExcel($fileName); return $fileName; } else { echo ini_get('upload_max_filesize'); echo "Sorry, there was an error uploading your file."; } } return $data; }

在你的JavaScript 中：
var form = document.forms.namedItem("excelForm");
form.addEventListener('submit', function(ev){
oData = new FormData(this);
oData.append("CustomField", "This is some extra data");
var oReq = new XMLHttpRequest();
oReq.onreadystatechange= function(oEvent){
if(this.readyState == 4 && this.status == 200){
$("#downloadButton").attr("style", "visibility: visible;")
alert(this.responseText)
} else {
alert(this.status);
}
};
oReq.send(oData);
ev.preventDefault();
}, false);
// ensure that your php file is in the correct directory and is using '.php'
oReq.open("POST", "./excel.php");
// don't forget to send
oReq.send();
在您的PHP文件中：
// your class and method goes here
public function actionexcel(){ ... }
echo $class->actionexcel();
