Passing data from java file to ajax I have a java class printing the progress of a process as 1%, 2%, 3%. Now I want to read this progress using AJAX requests and continuously update the progress in the webpage. I cannot convert the java file into a servlet as it is being used as an scriptlet by Jasper. Scriptlet code is : public void afterDetailEval() throws JRScriptletException{ count = (Integer) this.getVariableValue("count"); out.println(count); Thread.sleep(200); } How can I read the data printed by java from an AJAX request? Any help will be greatly appreciated!

Ajax/jQuery autocomplete in search box (Shopify) I am looking to get autocomplete setup on my search bars within my Shopify shop- this uses Liquid and ajax I found this tutorial, and implemented it as it says, however it is not working, nothing gets autocompleted on any search bar on the site- I think it may be quite old and was written before the updates/changes to Minimal/Shopify search functionality. https://help.shopify.com/themes/customization/store/enable-autocomplete-for-search-boxes I can follow it through with Chrome dev tools, and it seems like it gets stuck where it adds the search-results list $('<ul class="search-results"></ul>').appendTo($(this)).hide(); , this doesn't appear when tracing the HTML of the page. This means that when it later tries to find this list var resultsList = form.find('.search-results'); it doesn't find it, and thus cannot populate with items. $('<ul class="search-results"></ul...

Ajax success function with python: odd behavior I found an odd behavior when trying to use data on the browser-side, which is sent by a python script client-side. The ajax call is: $.ajax({ async: true, type: "POST", url: "/path/cgi-bin/pyscript.py", data: JSON.stringify(my_array), dataType: "html", success : function(data) { document.getElementById("ajaxAnchor").innerHTML = data + "Some random string to test display" } }); } I wanted to send back to data the result of a print() in the python script, but this only works in an unusually specific case. For the printed data to be sent back, there must first exist a print() executed with an n at the end. data print() print() n print("This line won't be sent to browser but is necessary n") print("This text will be sent back") And it's not just about adding the line break, because the following example won't work: ...
