问题描述
我对angularjs很陌生。我无法在线找到解决方案。我想从文件中读取文本。我试图按照这个例子。
但是,由于我使用的是TypeScript,因此我收到此错误信息
<$ c $ 。C>的document.getElementById( '的FileInput')文件[0];
错误:
属性'文件'在'HTMLElement'类型上不存在。
请向我建议我如何使用这些文件。
这个例子应该可以正常工作,也许你在那里做错了什么。然而,你可以像这样测试你的代码,用 fileChanged(event)
替换 fileChanged()
,然后获取文件通过 event.target.files
function fileChanged(event){var target = event .target || event.srcElement;的console.log(target.files); console.log(document.getElementById('fileInput')。files);}
< DIV> < input ng-model =csvonchange =fileChanged(event)type =fileid =fileInput/>< / div>
I am very new to angularjs. I wasn't able to find the solution online.I would like to read the text from a file. I was trying to follow this example.FileReader not loading file properly using AngularJS
However, since I'm using TypeScript, I receive this error for this line
document.getElementById('fileInput').files[0];
Error:Property 'files' does not exist on type 'HTMLElement'.
Please suggest me how I can cast to use the files.
This should work fine from that example, maybe you're doing something wrong there. However, you may test your code like this, replace fileChanged()
by fileChanged(event)
and then get the files by event.target.files
function fileChanged(event) {
var target = event.target || event.srcElement;
console.log(target.files);
console.log(document.getElementById('fileInput').files);
}
<div>
<input ng-model="csv"
onchange="fileChanged(event)"
type="file" id="fileInput"/>
</div>
