解决底部菜单被输入放顶上去的问题

//解决底部菜单被输入法顶上去
window.onresize = function () {

var h = $(window).height();
// console.log(h);
//console.log(h+','+window.screen.availHeight)
var u = navigator.userAgent;

if(u.indexOf('Android') > -1|| u.indexOf('Linux') > -1) {
if(h <= window.screen.availHeight/2){
//h <= 2window.screen.availHeight/3当底部菜单上还有其他固定内容是，可以用2/3,3/4...解决此类问题
$('.bottom').css({'position':'absolute',"bottom":"0",'display':'none'});
$('.apply-btn').css({'position':'absolute',"bottom":"5em",'display':'none'});
}else{
$('.bottom').css({'position':'fixed','display':'block'});
$('.apply-btn').css({'position':'fixed','display':'block'});
}
}
}

//苹果手机以下代码即可解决
$('input').on('focus',function(){
$('.bottom,.apply-btn').hide();
});
$('input').on('blur',function(){
$('.bottom,.apply-btn').show();
});
