我想知道是否可以使用input type="file"
选择pdf文件并使用PDFJS打开它
最佳答案
您应该能够使用FileReader将文件对象的内容作为类型化数组来获取,PDFJS接受该对象(http://mozilla.github.io/pdf.js/api/draft/PDFJS.html)
//Step 1: Get the file from the input element
inputElement.onchange = function(event) {
var file = event.target.files[0];
//Step 2: Read the file using file reader
var fileReader = new FileReader();
fileReader.onload = function() {
//Step 4:turn array buffer into typed array
var typedarray = new Uint8Array(this.result);
//Step 5:PDFJS should be able to read this
PDFJS.getDocument(typedarray).then(function(pdf) {
// do stuff
});
};
//Step 3:Read the file as ArrayBuffer
fileReader.readAsArrayBuffer(file);
}
