Adding onClick event dynamically using jQuery

Due to a plugin being used, I can't add the "onClick" attribute to the HTML form inputs like usual. A plugin is handling the forms part in my site and it doesn't give an option to do this automatically.

Basically I have this input:

<input type="text" id="bfCaptchaEntry" name="bfCaptchaEntry" style="">

I want to add an onClick to it with jQuery onload for it to be like this:

<input onClick="myfunction()" type="text" id="bfCaptchaEntry" name="bfCaptchaEntry" style="">

How do I go about doing this?

I know this might not be standard practice but seems like the easiest option to do in my situation.

I'm a newbie to jQuery so any help is very much appreciated.

You can use the click event and call your function or move your logic into the handler:

$("#bfCaptchaEntry").click(function(){ myFunction(); });

You can use the click event and set your function as the handler:

$("#bfCaptchaEntry").click(myFunction);

.click()

Bind an event handler to the "click" JavaScript event, or trigger that event on an element.

You can use the on event bound to "click" and call your function or move your logic into the handler:

$("#bfCaptchaEntry").on("click", function(){ myFunction(); });

You can use the on event bound to "click" and set your function as the handler:

$("#bfCaptchaEntry").on("click", myFunction);

.on()

Attach an event handler function for one or more events to the selected elements.

Answer

try this approach if you know your object client name ( it is not important that it is Button or TextBox )

$('#ButtonName').removeAttr('onclick');
$('#ButtonName').attr('onClick', 'FunctionName(this);');

try this ones if you want add onClick event to a server object with JQuery

$('#' + '<%= ButtonName.ClientID %>').removeAttr('onclick');
$('#' + '<%= ButtonName.ClientID %>').attr('onClick', 'FunctionName(this);');
Answer

Try below approach,

$('#bfCaptchaEntry').on('click', myfunction);

or in case jQuery is not an absolute necessaity then try below,

document.getElementById('bfCaptchaEntry').onclick = myfunction;

However the above method has few drawbacks as it set onclick as a property rather than being registered as handler...

Answer
$("#bfCaptchaEntry").click(function(){
    myFunction();
});
Answer

Or you can use an arrow function to define it:

$(document).ready(() => {
  $('#bfCaptchaEntry').click(()=>{

  });
});

For better browser support:

$(document).ready(function() {
  $('#bfCaptchaEntry').click(()=>{

  });
});
Answer
let a = $("<a>bfCaptchaEntry</a>");
a.attr("onClick", "function(" + someParameter+ ")");
