模拟ie9的placeholder

ie9 的input框没有placeholder属性 啧啧啧~~~

所以就用span标签来模拟一下

先判断浏览器类型

if(navigator.useAgent.indexOf("MSIE 9.0")>0){
   啦啦啦，现在用的是ie9浏览器     
   我想我家东东了~~~
}

封装函数

function ifie9(){
    //判断是否是ie9
    if(navigator.userAgent.indexOf("MSIE 9.0")>0){
        //input元素
        $(".ipt").each(function(){
            var self = $(this);
            self.parent().append('<span class="placeholder" data-type = "placeholder">我爱东东</span>')
            if(self.val() != ''){
                self.parent().find("span.placeholder").hide()
            }else{
                self.parent().find("span.placeholder").show()
            }
        }).on('foucs',function(){
            $(this).parent().find("span.placeholder").hide()
        }).on('blur',function(){
            var self = $(this);
            if(self.val != ''){
                self.parent().find("span.placeholder").hide()
            }else{
                self.parent().find("span.placeholder").show()
            }
        });
        $("span.placeholder").on('clock',function(){
            $(this).hide()
        })
    }
}

function ifie9(){

    //判断是否是ie9

    if(navigator.userAgent.indexOf("MSIE 9.0")>){

        //input元素

        $(".ipt").each(function(){

            var self = $(this);

            self.parent().append('<span class="placeholder" data-type = "placeholder"></span>')

            if(self.val() != ''){

                self.parent().find("span.placeholder").hide()

            }else{

                self.parent().find("span.placeholder").show()

            }

        }).on('foucs',function(){

            $(this).parent().find("span.placeholder").hide()

        }).on('blur',function(){

            var self = $(this);

            if(self.val != ''){

                self.parent().find("span.placeholder").hide()

            }else{

                self.parent().find("span.placeholder").show()

            }

        });

        $("span.placeholder").on('clock',function(){

            $(this).hide()

        })

    }
