$(document).ready(function(){

    $("body, input, textarea").keypress(function(e){
        if(e.which==13) $("#btnSubmit").click();
    });
});

希望这对你有所帮助!!

我做的最简单的方法是:

$("#element").keydown(function(event) {
    if (event.keyCode == 13) {
        localiza_cep(this.value);
    }
});

有些浏览器使用keyCode，有些使用which。如果你正在使用jQuery，你可以可靠地使用它，因为jQuery标准化了东西。实际上,

$('#searchbox input').bind('keypress', function(e) {
    if(e.keyCode==13){

    }
});

．.． 这个例子阻止表单提交(通常是捕获击键#13时的基本意图):

$('input#search').keypress(function(e) {
  if (e.which == '13') {
     e.preventDefault();
     doSomethingWith(this.value);
   }
});

这是一个jquery扩展，将处理进入键被按下。

(function ($) {
    $.prototype.enterPressed = function (fn) {
        $(this).keyup(function (e) {
            if ((e.keyCode || e.which) == 13) {
                fn();
            }
        });
    };
}(jQuery || {}));

$("#myInput").enterPressed(function() {
    //do something
});
