Apart from the mentioned points and assuming you already have a proper setup to serve your python script and return the response. You should submit an asynchronous request, especially if the python code does some heavy computation.
function postData(input) {
$.ajax({
type: "POST",
url: "/reverse_pca.py",
data: { param: input },
success: callbackFunc
});
}
function callbackFunc(response) {
// do something with the response
console.log(response);
}
postData('data to process');
If you only do some light computation and you have no problem working with a code deprecated as of jQuery 1.8, go with the synchronous approach. This is not recommended as it blocks the main thread.
function runPyScript(input){
var jqXHR = $.ajax({
type: "POST",
url: "/reverse_pca.py",
async: false,
data: { param: input }
});
return jqXHR.responseText;
}
// do something with the response
response= runPyScript('data to process');
console.log(response);
