onclick

问题 Is there a way to include some php file at javascript onClick ? like, if(isset(something)) ? include "file.php"; Please help! 回答1: No. That's PHP syntax.

You can use AJAX to make a request to the server for a file and display its contents using JS, though. jQuery has a simple method called .ajax() for this $.ajax({ url: 'file.php',

问题 So im sure this is probably a fairly easy question but I am stumped because I am a beginner. I am looking to pass a value from one class to another, and I have my helper function down and working just fine. If i create an integer outside of my onClick I can pass it no problem. If I create it inside the onClick though it doesn't seem to make it out. package com.movi.easypar; //import java.util.logging.Handler; import android.app.Activity; import android.app.AlertDialog; import android.content

MainActivityFunctionalTest public class MainActivityFunctionalTest extends ActivityInstrumentationTestCase2<MainActivity> { // ... public void
