解决移动端 footer fixd 定位被键盘顶起来的方案

 

直接上代码：

$(document).ready(function () {
　　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
　　var h=$(window).height(); //获取窗口高度
　　$(window).resize(function() {     //检测窗口高度变化
　　if($(window).height()<h){    //判断
　　　　$('#footer').hide();
　　}
　　if($(window).height()>=h){
　　　　if(isAndroid){
　　　　$('#footer').show();
　　　　$("input").blur();
　　}else if(isiOS){

　　　　$('#footer').show();
　　}
}

});
});
