我正在尝试使用ajax上传文件但由于某些原因它无法正常工作,你能看到什么了吗?
function upload(myform)
var file = this.files[0];
var formData = new FormData();
formData.append("material_file", document.getElementById("myfile"));
xmlhttp = new XMLHttpRequest();
xmlhttp.addEventListener('progress', function(e) {
var done = e.position || e.loaded, total = e.totalSize || e.total;
console.log('xmlhttp progress: ' + (Math.floor(done/total*1000)/10) + '%');
}, false);
if ( xmlhttp.upload ) {
xmlhttp.upload.onprogress = function(e) {
var done = e.position || e.loaded, total = e.totalSize || e.total;
console.log('xmlhttp.upload progress: ' + done + ' / ' + total + ' = ' + (Math.floor(done/total*1000)/10) + '%');
};
}
xmlhttp.onreadystatechange = function(e) {
if ( 4 == this.readyState ) {
console.log(['xmlhttp upload complete', e]);
}
};
xmlhttp.open('post', process_pdf.php, true);
xmlhttp.setRequestHeader("Content-Type","multipart/form-data");
xmlhttp.send(formData);
}
<form onsubmit="upload(this)">
<input type="file" name="myfile">
</form>
当我浏览到该文件并单击“提交时,我收到错误

根据错误,您需要在之前创建myForm
变量。
但是,更大的问题是one can't upload files with AJAX alone.尝试使用像SWFupload这样的库。
如果您不想使用Flash或其他插件,则需要跳过AJAX并直接使用POST
。
<form method="post" enctype="multipart/form-data" action="/PATH/TO FILE">
<input type="file" name="myfile">
<input type="submit" value="upload file">
</form>
