You can use similar technique to read a file:

您可以使用类似的技术来读取文件:

var pagesDetailFile = Ti.Filesystem.getFile(Titanium.Filesystem.applicationDataDirectory, "demo.txt"); 
alert(pagesDetailFile.read()); // Read the file
pagesDetailFile = null; // remember to release the file

You should read the documentation carefully for available functions.

您应该仔细阅读文档以了解可用的功能。

You will have to use the techniques described at https://appcelerator.github.io/appc-docs/platform/latest/#!/guide/Communication_Between_WebViews_and_Titanium to fire an event in the WebView HTML which you'd pick up in Titanium JS, get the file and then use evalJS or fireEvent to send it back to the WebView HTML.

您将必须使用https://appcelerator.github.io/appc-docs/platform/latest/#!/guide/Communication_Between_WebViews_and_Titanium中描述的技术来触发您在Titanium JS中获取的WebView HTML中的事件,获取文件,然后使用evalJS或fireEvent将其发送回WebView HTML。

I used jquery in order to read data from the simulator and it works for devices too.

我使用jquery来从模拟器中读取数据,它也适用于设备。

var filePath = "/Users/anonymous/Library/Developer/CoreSimulator/Devices/FE1CFXXX0AC-D5BD-9615-C58D80B5A9C6/data/Containers/Data/Application/2D25XXXX-4687-B28A-1EA7B7EA3013/Documents/admin/content.txt";
$.ajax({
    url: filePath,
    context: document.body,
    async: false,
    success: function(response){
        Ti.API.info("FILE CONTENT " + response);
    },
    error: function(data){
        alert('does not exist');
    }
});

filePath is actual path in which we are storing data.

filePath是我们存储数据的实际路径。
