I try to create button which starts an alert after a click event. Something like that : 

    <body>
    <div class="app">
        <h1>Apache Cordova</h1>
        <div id="deviceready" class="blink">
            <p class="event listening">Connecting to Device</p>
            <p class="event received">Device is Ready</p>

        </div>
        <button onclick="alert('salut')" id="boutonAlerte">Alerte</button>
    </div>
    <script type="text/javascript" src="cordova.js"></script>
    <script type="text/javascript" src="js/index.js"></script> </body>

but the problem is that my onclick doesn't work. A lot of people tell me to try it on javascript so I've decided to write something like that : 

function onAlertClick() {
  alert("ceci est une alerte");
}

alert("test2");

var bA = document.getElementById("boutonAlerte");
bA.addEventListener("onclick", onAlertClick());

But this is the same thing.

Any ideas ?

Solution

// Function to change the content of t2

function modifyText() {
  var t2 = document.getElementById("t2");
  if (t2.firstChild.nodeValue == "three") {
    t2.firstChild.nodeValue = "two";
  } else {
    t2.firstChild.nodeValue = "three";
  }
}

// add event listener to table

var el = document.getElementById("outside");
el.addEventListener("click", modifyText, false);

You can try to do the following: 

$("#boutonAlerte").on('click', function(){ 
 alert("Clicked!");
});

Then remove the onclick from your button tag and make sure that you included the jQuery library in your HTML o course.

If you want to use JavaScript only you should do :

<button onclick="myFunction();" id="boutonAlerte">Alerte</button>

<script> 
  function myFunction(){
   alert("clicked!");
  }
</script>

Here is a jQuery example

html

            <a href="#" class="start-button">EXECUTE</a>

jquery

$(".start-button").click(function (e) {  //note that 'onclick="HandleExec();return false;" doesnt work
    e.preventDefault();
    // here you can handle the click code you wanted
});

make sure that you call event.preventDefault(); so it doesn't try to go to the href in the html tag. That will just reload the cordova app in this case.

The solution is quite simple, actually. All elements, that you would like to have the click event working on, should have the CSS rule "cursor: pointer;"

You can find a working example here: https://haensel.pro/apache-cordova/apache-cordova-ios-click-event-not-working-quick-how-to

Try adding jQuery click event, which are working fine with my cordova apps

<script type="text/javascript" src="https://code.jquery.com/jquery-1.12.3.js"></script>

<script type="text/javascript">
   $("#boutonAlerte").click(function(){
       alert("ceci est une alerte");
   });
</script>

Here is JSFiddle link

Define a clickhandler that you can use later on:

var clickHandler = ('ontouchstart' in document.documentElement ? "touchstart" : "click");

$("a").bind(clickHandler, function(e) {
    alert("clicked or tapped. This button used: " + clickHandler);
});

This will trigger click on non-touch devices and touchstart on touch devices.

When that is said, I will strongly recommend using Fast click instead, and use regular click-events. With the above solution, you will trigger "touchstart" on links when you swipe on it to scroll the page for instance - which is not ideal.
