在Javascript（Angular）中读取，更改和保存文档 [英] Read, change and save doc in Javascript (Angular)
问题描述
我需要读取文件（.doc）然后替换doc中的一些数据然后发送到print（doc或pdf）。
I need to read file (.doc) then replace some data in doc and then send to print (doc or pdf).
第一步我尝试从文档中读取数据。从.txt起作用，但来自.doc no :(
At first step I try to read data from docs. From .txt its work, but from .doc no :(
我在jsfiddle http://jsfiddle.net/qo0fxo50/
I did example in jsfiddle http://jsfiddle.net/qo0fxo50/
我尝试这样做：
<h1>Select file</h1>
<input type="file" on-read-file="showContent($fileContent)" />
<div>
<h2>File content is:</h2>
<pre>{{ contentfile }}</pre>
</div>
和指令（on-read-file）：
And directive (on-read-file):
directives.directive('onReadFile', function ($parse) {
return {
restrict: 'A',
scope: false,
link: function(scope, element, attrs) {
var fn = $parse(attrs.onReadFile);
element.on('change', function(onChangeEvent) {
var reader = new FileReader();
reader.readAsText((onChangeEvent.target).files[0], 'CP1251');
reader.onload = function(onLoadEvent) {
scope.$apply(function() {
fn(scope, {$fileContent:onLoadEvent.target.result});
});
};
});
}
};
});
我在jsfiddle做了一个例子 http://jsfiddle.net/qo0fxo50/

推荐答案
.doc是专有的和二进制格式（也有多个不兼容的版本）。
这意味着它是一堆未记录的字节而不是像.txt一样的字符串。
.doc is a proprietary and binary format (also there are multiple incompatible versions). That means it's a bunch of undocumented bytes instead of some charackters as with .txt.
除非你了解细节，否则你不会得到任何东西。该格式或找到一个可以帮助您阅读它的库。我建议将'.doc-contents自动化为你可以解析的东西 - 用工具进行转换（应该有一些东西，但不要考虑准确的结果），或者更好的是不要使用.doc。
You won't get anything out of it unless you understand the details of that format or find a library that helps you to read it. I'd suggest automate '.doc-contents to something you can parse'-conversion with a tool (there should be something out there, but don't exspect accurate results) or even better don't use .doc.
至于新的.docx格式，它应该更容易获取内容，因为它们基本上是.xml。
As for the new .docx formats it should be a little easier to get contents, as they are basically .xml.
