pdf文件上传ajax html

尝试

json

从

files[0]

属性创建对象，将其转换

file

为

base64

字符串

js

$("#image").on("change", function(e) {  var name = $("#af_rpta_propertyland_filename").val()  , file = e.target.files[0]  , filename = name.length > 1 ? name + ".pdf" : file.name  , filetype = file.type  , filesize = file.size  , data = {      "filename":filename,      "filetype":filetype,      "filesize":filesize    }  , reader = new FileReader();    reader.onload = function(e) {      data.file_base64 = e.target.result.split(/,/)[1];        $.post("fileupload.php", {file:data}, "json")        .then(function(data) {          // parse `json` string `data`          var filedata = JSON.parse(data)          // do stuff with `data` (`file`) object          , results = $("<a />", {     "href": "data:" + filedata.filetype   + ";base64," + filedata.file_base64,     "download": filedata.filename,     "target": "_blank",     "text": filedata.filename   });          $("body").append("<br>download:", results[0]);        }, function(jqxhr, textStatus, errorThrown) {          console.log(textStatus, errorThrown)        })    };    reader.readAsDataURL(file)});

的PHP

<?php  if (isset($_POST["file"])) {    // do php stuff    // call `json_enpre` on `file` object    $file = json_enpre($_POST["file"]);    // return `file` as `json` string    echo $file;};
