键盘事件

一、监听回车键调用事件
1、jquery:

$("dom").keypress(function (even) {if (even.which == 13) {// 事件处理}
});

2、JavaScript：

document.onkeydown=function(event){var e = event || window.event || arguments.callee.caller.arguments[0];
    if(e && e.keyCode==27){ // 按 Esc 
        // 事件处理
      }           
     if(e && e.keyCode==13){ // enter 键
        // 事件处理
    }
}

3、键码阐明：

二、挪动端键盘事件处理及兼容性解决方案
1、操作系统判断

  function navigator(){
        var u = navigator.userAgent;
        var isAndroid = u.indexOf('Android') > -1 || u.indexOf('Adr') > -1; //android 终端
        var isiOS = !!u.match(/\(i[^;]+;(U;)? CPU.+Mac OS X/); //ios 终端
        if(isAndroid){// 安卓};
        if(isiOS){//ios};
    };

2、键盘的收起和开展

$(document).on("focusin",function(){// 键盘弹出~~~~})
 
 
$(document).on("focusout",function(){// 键盘收起})

3、ios 键盘收起

function navigator(){
        var u = navigator.userAgent;
        var isAndroid = u.indexOf('Android') > -1 || u.indexOf('Adr') > -1; //android 终端
        var isiOS = !!u.match(/\(i[^;]+;(U;)? CPU.+Mac OS X/); //ios 终端
        if(isAndroid){ };
        if(isiOS){$(document).on("focusin",function(){
                                // 键盘弹起时，让滚动条滚动到底部，$(window).scrollTop($("body").height());
                                 // 设置定时器
                setTimeout(function(){
                                        // 获取文档高度
                    var clientHeight= document.body.clientHeight;
                                         // 获取滚动高度 -- 也就是键盘高度
                    var scrollTop = document.body.scrollTop;
                    // 让你想要的底部元素的 bottom：键盘高度。$(".bottom").css("bottom",scrollTop+"px");
                    // 最初再设置一个定时器让滚动条回到顶部。setTimeout(function(){$(window).scrollTop(0);
                                          },300);
                },300);
            });
            $(document).on('focusout', function () {
                 // 软键盘收起的事件处理
                                 // 让底部元素回到底部。$(".bottom").css("bottom","0");
            });
        };
    };

4、android 键盘收起

function navigator(){
        var u = navigator.userAgent;
        var isAndroid = u.indexOf('Android') > -1 || u.indexOf('Adr') > -1; //android 终端
        var isiOS = !!u.match(/\(i[^;]+;(U;)? CPU.+Mac OS X/); //ios 终端
        if(isAndroid){var wHeight = $(window).innerHeight();   // 获取初始可视       窗口高度
                      $(window).resize(function() {         // 监测窗口大小的变动事件
                         var hh = $(window).innerHeight();     // 以后可视窗口高度
                         var viewTop = $(window).scrollTop();   // 可视窗口高度顶部间隔网页顶部的间隔
                         if(wHeight > hh){// 能够作为虚构键盘弹出事件}else{// 能够作为虚构键盘敞开事件};
                              wHeight = hh;
                        });
        };
        if(isiOS){};};
