does asp.net mvc client side validation using jquery work views which use html helpers generate html controls? work standard html controls? it possible use validation without turning htmlhelpers. see article details how mvc works in background unobtrusive validation. http://www.blinkingcaret.com/2016/03/23/manually-use-mvc-client-side-validation/ though think unless have specific requirement, rather stick helpers, make life easier.

i using scanner methods nextint() , nextline() reading input. basically, looks this: system.out.println("enter numerical value"); int option; option = input.nextint();//read numerical value input system.out.println("enter 1st string"); string string1 = input.nextline();//read 1st string (this skipped) system.out.println("enter 2nd string"); string string2 = input.nextline();//read 2nd string (this appears right after reading numerical value) the problem after entering numerical value, first input.nextline() skipped , second input.nextline() executed, output looks this: enter numerical value 3 //this input enter 1st string //the program supposed stop here , wait input, skipped enter 2nd string //and line executed , waits input i tested application , looks problem lies in using input.nextint() . if delete it, both string1 = input.nextline() , string2 = input.nextline() executed want them be. that's because scanner...

this question has answer here: python - flask default route possible? 1 answer i'm using flask react. i'd create catch route similar (although doesn't work): @app.route('*') def get(): return render_template('index.html') since app use react , it's using index.html mount react components, i'd every route request point index.html page in templates. there way (or using redirect best way)? you can follow guideline: http://flask.pocoo.org/snippets/57/ from flask import flask app = flask(__name__) @app.route('/', defaults={'path': ''}) @app.route('/<path:path>') def catch_all(path): return 'you want path: %s' % path if __name__ == '__main__': app.run()
