本文实例分享了原生JS版和jQuery 版实现文件上传功能的例子,供大家参考,具体内容如下
<!doctype html><html lang="zh"><head><meta charset="utf-8"><title>HTML5 Ajax Uploader</title><script src="jquery-2.1.1.min.js"></script></head><body><p><input type="file" id="upfile"></p><p><input type="button" id="upJS" value="用原生JS上传"></p><p><input type="button" id="upJQuery" value="用jQuery上传"></p><script>/*原生JS版*/document.getElementById("upJS").onclick = function() { /* FormData 是表单数据类 */ var fd = new FormData(); var ajax = new XMLHttpRequest(); fd.append("upload", 1); /* 把文件添加到表单里 */ fd.append("upfile", document.getElementById("upfile").files[0]); ajax.open("post", "test.php", true); ajax.onload = function () { console.log(ajax.responseText); }; ajax.send(fd); }/* jQuery 版 */$("#upJQuery").on("click", function() { var fd = new FormData(); fd.append("upload", 1); fd.append("upfile", $("#upfile").get(0).files[0]); $.ajax({ url: "test.php", type: "POST", processData: false, contentType: false, data: fd, success: function(d) {console.log(d); } });});</script></body></html>php代码:
<?phpif (isset($_POST["upload"])) { var_dump($_FILES);move_uploaded_file($_FILES["upfile"]["tmp_name"], "up_tmp/".time().".dat");//header("location: test.php");exit;}?>以上就是本文的全部内容,希望对大家的学习有所帮助。
