觸發按鍵點擊

Question

$(document).keypress(function(event) { 
    // + 
    if (event.which == 43) { 
     // ... 
    } 
} 

HTML

<input type="button" value="+" name="plus"> 

我怎樣才能觸發與+的按鍵方法單擊按鈕時？

$('input[name="plus"]').click(function(){ 
    // ??? How to go further ??? 
}) 

Answer 1

在這裏你去

var e = jQuery.Event("keypress"); 
e.which = 43; // # Some key code value 
$(document).trigger(e);

Answer 2

$(document).on('keypress',function(e) { 
    if (e.keyCode == 43 || e.which == 43) { 
     var identifier = e.target.id; 
     console.log(e.target.id); 
     $('#' + identifier).click(); 
    } 
});
