How to bind the enter/return key to user-defined function

I'm developing an application that runs on one page, and does not reload. I have a form wit开发者_JS百科h only an input type text, no submit button. I included the onchange event, after filling the textbox with data, I want to execute the function bound to the onchange event when I press enter, but the form is rather submitted and [it attempts to load a new page]. Please what do I do? Thanks

You can hook the keypress event on the text box and call your handler, and cancel the event to prevent the form submission:

$("selector_for_your_text_box").keypress(function(event) {
    if (event.which === 13) {
        // call your `change` logic here

        // Cancel the event
        return false;
    }
});

Live example

This should work:

$(function() {
   $('#yourInput').keypress(function(event) {
      var key = event.keyCode || event.which;
      if (key == 13) {
         event.preventDefault();
         // call your function here
   });
});

Yuo can bind to the keypress event on the input:

$('#inputfieldid').keypress(function() {
  alert('Handler for .keypress() called.');
});
