Bagaimana Cara Menangani Acara Klik Tombol di jQuery?

Saya perlu memiliki tombol dan menangani acara di jQuery. Dan saya menulis kode ini tetapi tidak berhasil. Apakah saya melewatkan sesuatu?

<!-- Begin Button -->  
<div class="demo">
<br> <br> <br>   
<input id = "btnSubmit" type="submit" value="Release"/>
<br> <br> <br>  
</div>
<!-- End Button -->

Dan di file javascript

function btnClick()
{
    //    button click
    $("#btnSubmit").button().click(function(){
        alert("button");
    });    
}

Anda harus meletakkan event handler di $ (document) .ready () event:

$(document).ready(function() {
    $("#btnSubmit").click(function(){
        alert("button");
    }); 
});

$(document).ready(function(){

     $('your selector').bind("click",function(){
            // your statements;
     });

     // you can use the above or the one shown below

     $('your selector').click(function(e){
         e.preventDefault();
         // your statements;
     });


});

$('#btnSubmit').click(function(){
    alert("button");
});

atau

//Use this code if button is appended in the DOM
$(document).on('click','#btnSubmit',function(){
    alert("button");
});

Lihat dokumentasi untuk informasi lebih lanjut:
https://api.jquery.com/click/

 $("#btnSubmit").click(function(){
        alert("button");
    });    

Coba ini:

$(document).on('click', '#btnClick', function(){ 
    alert("button is clicked");
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
 <button id="btnClick">Click me</button> 

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>

<script>
$(document).ready(function(){
  $("#button").click(function(){
    alert("Hello");
  });
});
</script>

<input type="button" id="button" value="Click me">

<script type="text/javascript">

    $(document).ready(function() {

    $("#Button1").click(function() {

        alert("hello");

    });

    }
    );

</script>

$('#btnSubmit').click(function(event){
    alert("Button Clicked");
});

atau karena Anda menggunakan tombol kirim sehingga Anda dapat menulis kode Anda di acara validasi formulir seperti

$('#myForm').validate(function(){
    alert("Hello World!!");
});

Bekerja untukku

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js" type="text/javascript"></script>
<script type="text/javascript">

$("#btn").click(function() {
    alert("email")
});

</script>
