jQuery - 键入'home'做某事(keyup)

Question

所以当我在我的网站上键入"home"时，我想做点什么。我认为这可以使用keyup和可能的绑定来完成？

h-72o-79m-77e-69

我设法做到了，但我相信还有更好的方法。。

if (e.keyCode == 72) {
    $(document).keyup(function (u) {
        if (u.keyCode == 79) {
            $(document).keyup(function (l) {
                if (l.keyCode == 77) {...

Answer 1

var reading = "";
$(window).keypress(function(e){
    reading += String.fromCharCode(e.which);
    if("home".indexOf(reading) < 0)
        reading = "";
    else if(reading == "home"){
        //DO WHAT YOU WANT
    }
}

Answer 2

您应该做的是保留最后n个按键的缓冲区。然后你所要做的就是检查字符串中是否出现了单词"home"。我会让你整理细节，但基本结构不应该太难。

//Example of checking if home is contained within "myString"
myString.indexOf("home") != -1;
var keyBuffer;
$(document).keyup(function(u){
    //Keep a key buffer.
    keyBuffer += u.keyCode;
    //Trim keybuffer so it isn't too long.
    //Check for the presence of any of your keywords such as "home" and respond.
});

基于jQuery.com 上的Konami代码实现

if ( window.addEventListener ) {
 var hkeys = [], hhome = "72,79,77,69";
window.addEventListener("keydown", function(e){
hkeys.push( e.keyCode );
if ( hkeys.toString().indexOf( hhome ) >= 0 )
 alert("Home!!!");
 hkeys = [];
}, true);
}

你可以试试这个

​$(function(){
    $(document).keyup(function(e){
        e.preventDefault();
        var str=$(e.target).val();
        if(str.toLowerCase()=='home')
        {
            alert("Got home here !");
        }      
    });
});​
