I have a search box which is a text type and has a click button that initiates the Find() function.
How can I enable searching by pressing Enter inside the textbox?

When your text input is enclosed within a form element, you have the ability to connect an onSubmit event handler or use jQuery's .submit() method on the form itself. This trigger will activate when the user hits the enter key while focused inside the text input field.
To implement functionality for pressing the "enter" key on an input field, use ng-keypress on the input element and check for the keycode of the "enter" key:
<input type="text" ng-keypress="($event.which === 13) ? Find() : void(0)" />
If you are not using jQuery, consider using $event.keyCode, although ensuring compatibility across browsers can be challenging as discussed here.
If you have a directive that includes this template, handle the event in the link function and call the Find function there. Otherwise, enclose the input within a form tag and define an on-submit attribute on the form. Be sure to verify IE compatibility, as older versions like IE7 may require a hidden <input type="submit" /> in the form for the enter key to work properly.
document.onkeydown = function(event) {//execute when a key is pressed
event = event || window.event;
if (13 == event.keyCode) {//check if the key pressed is enter
if (document.activeElement.className== "search_input"){//verify if focus is on the input field with class search_input
PerformSearch() //invoke the search function
return false;//prevent default enter action
}
}
}
In my experience, Angular-UI has consistently been reliable. The ui-keypress directive is a great solution for this situation. Check it out at http://angular-ui.github.io/ui-utils/#/keypress. Remember, the keycode for the Return/Enter key is 13.
