从 JavaScript 代码调用 Python 函数 [英] Call Python function from JavaScript code

问题描述

我想从 JavaScript 代码中调用 Python 函数，因为 JavaScript 中没有替代方案来执行我想要的操作.这可能吗?你能调整下面的代码片段吗?

I'd like to call a Python function from JavaScript code, because there isn't an alternative in JavaScript for doing what I want. Is this possible? Could you adjust the below snippet to work?

JavaScript 代码:

JavaScript code:

var tag = document.getElementsByTagName("p")[0];
text = tag.innerHTML;
// Here I would like to call the Python interpreter with Python function
arrOfStrings = openSomehowPythonInterpreter("~/pythoncode.py", "processParagraph(text)");

~/pythoncode.py 包含使用高级库的函数，这些函数在 JavaScript 中没有易于编写的等效项:

~/pythoncode.py contains functions using advanced libraries that don't have an easy to write equivalent in JavaScript:

import nltk # is not in JavaScript
def processParagraph(text):
  ...
  nltk calls
  ...
  return lst # returns a list of strings (will be converted to JavaScript array)

推荐答案

您需要做的只是向您的 Python 代码发出 ajax 请求.你可以用 jquery http://api.jquery.com/jQuery.ajax/ 做到这一点，或者只使用 javascript

All you need is to make an ajax request to your pythoncode. You can do this with jquery http://api.jquery.com/jQuery.ajax/, or use just javascript

$.ajax({
  type: "POST",
  url: "~/pythoncode.py",
  data: { param: text}
}).done(function( o ) {
   // do something
});
