记一下 JS 通过 input 加载 pdf
//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
const loadingTask = pdfjsLib.getDocument(typedarray);
loadingTask.promise.then((pdf) => {
// The document is loaded here...
});
};
//Step 3:Read the file as ArrayBuffer
fileReader.readAsArrayBuffer(file);
};
另外一个方法，好像都差不多，不过上面的方法传值不是 { data: myData }
var reader = new FileReader();
reader.readAsArrayBuffer(input.files[0]);
reader.onload = function (e) {
var myData = new Uint8Array(e.target.result)
var docInitParams = { data: myData };
PDFJS.getDocument(docInitParams).then(function(pdf) {.....})
}
