WEB前端 怎么读取TXT内容

Answer 1

遇到了前端打开文件，读取文件信息的功能，分享一下：
<input type="file" (change)="openFile($event)" placeholder="Open file..." />

filecontent: any; //放置文件内容
filesToUpload: Array<File> = [];

getContent() {
this.readFile(this.filesToUpload).then((result) => {
this.filecontent = result;
}, (error) => {
console.error(error);
});
}

openFile(fileInput: any) {
this.filesToUpload = <Array<File>>fileInput.target.files;
this.getContent();
}

readFile(files: Array<File>) {
return new Promise((resolve, reject) => {
var fileReader = new FileReader();

fileReader.onload = function (e) {
resolve(fileReader.result);
return;
};
fileReader.readAsText(files[0]);
});
}
