Create data URIs on the fly?(即时创建数据 URI?)
问题描述
Is there a script (javascript / client side). That create data URIs on the fly. Now i create data URIs with a online base64 creator. And then put that output in the css file. But when i changing the images. Its a lot of work to do it. Is there a script, that can do it for me.?
The modern browsers now have good support for base64 encoding and decoding. There are two functions respectively for decoding and encoding base64 strings:
atob()
decodes a string of base-64 databtoa()
creates a base-64 encoded ASCII string from a "string" of binary data
This let's you create data uri's easily i.e
var longText = "Lorem ipsum....";
var dataUri = "data:text/plain;base64," + btoa(longText);
//a sample api expecting an uri
d3.csv(dataUri, function(parsed){
});
