I'm wondering if using plain javascript XMLHttpRequest object instead of
web2py ajax() can cause any problem or might be unsafe. The reason I've
decided to do so is that I need to pass the server response (json object)
to a js function as an argument.
My js code looks like this:
var query = document.getElementById('my-input-field').value;
var xhttp = new XMLHttpRequest();
xhttp.onreadystatechange = function() {
if (this.readyState == 4 && this.status == 200) {
var arg = JSON.parse(this.responseText);
processArguments(arg);
}
};
xhttp.open("POST", "/myaapp/controler/function/"+query, true);
xhttp.send();
Previously I used web2py ajax() function with :eval argument and short js
code as the part of the response to be executed for calling js function.
Then I've found XHTMLHttpRequest object works as well and is even easier to
use when we want execute js code after server response. Now I'm just
curious if it has ane disadvantage comparing to web2py ajax() or jQuery
$.ajax().
Thank you for your answer in advance.
