Calling my own function during with onClick

How do I call a user-define function such as this one using the onClick attribute of a input button? More specifically what special steps must I take in JQuery and what would the HTML markup look like? Thanks

function simClick(keyCode) {
            var e = jQuery.Event("keypress");
            e.keyCode = 8;
            $(document).trigger(e);
        }


<input type="button" ID="delBtn" c开发者_C百科lass="calcBtn" value="Del" onclick="???????" />


HTML

<input type="button" ID="delBtn" class="calcBtn" value="Del" />

Javascript in separate file

  // When the DOM is ready
$(function() {
      // Function that is executed w keypress or button click
    doThis = function() {

        // Stuff to do
    }

      // To do when element with ID delBtn is clicked
    $("#delBtn").click(function() {

        // Stuff to do when input is clicked
        doThis();
    });

     // To do when key is pressed
    $(document).keydown(function(event) {

        // Stuff to do when key is pressed
        // Can check which key was pressed here.
        var code = (event.keyCode ? event.keyCode : event.which);
        if(code == 8) { //Enter keycode 

            doThis();
        }
    });
});

There are many ways to attach a handler to when that button is clicked. Take a look at jQuery selectors.

You could also use the attribute equals selector

$("input[value='Del']")...... // For the input with a value of Del

I'm not sure what you quoted JS has to do with the input button, since it looks like you're trying to work with a keypress instead of a click in that function.... But the above jQuery is how you capture a click on that input button.

Take a look at, "Which key was pressed?"
