Answer 1

占位符未出现在ie9浏览器中

IE＆lt; 10不支持HTML5 placeholder属性。

Answer 2

Internet Explorer 9及更早版本不支持input标记的占位符属性。因此，要么使用Javascript来模拟效果，要么在输入旁边添加标签，要么忘记IE。

Answer 3

IE9不支持它。我尝试在IE9中创建相同的效果，我写了一个JavaScript函数来检查是否支持placehoder。如果不是，那么通过jQuery ...

在表单元素字段中显示文本

/*AN HTML5 INPUT ATTRIBUTE THATS REALLY COOL*/
var placeHolderSupport = ('placeholder' in document.createElement('input'));

/*IF PLACEHOLDER IS NOT SUPPORTED...*/
if(!placeHolderSupport) {

/*GET THE ID OF EACH FORM ELEMENT*/
fname       = $('#fname');
femail      = $('#femail');
furl        = $('#furl');
fcomment    = $('#fcomment');
fsubmit     = $('#sendbtn');

/*DEFINE DEFAULT VALUES FOR EACH INPUT FIELD*/
fnameval    = "Your Full Name";
femailval   = "Your E-mail Address - (It will not be shared!)";
furlval     = "Your Web Site";
fcommentval = "Your Message";



        /*ASSOCIATE THE DEFAULT VALUES TO THE FORM INPUT FIELDS*/
        fname.val(fnameval);
        femail.val(femailval);
        furl.val(furlval);
        fcomment.val(fcommentval);

        /*CYCLE THROUGH EACH INPUT FIELD TO...*/
            $.each([
            {selector: fname,   mvalue: fnameval},
            {selector: femail,  mvalue: femailval},
            //{selector: furl,    mvalue: furlval},
            {selector: fcomment,mvalue: fcommentval}
            ],function(i, obj) {

              /*...SHOW OR HIDE DEFAULT VALUES*/
                obj.selector.focus(function() {
                    if(this.value == obj.mvalue) { this.value = ''; };
                }).blur(function() {    
                    if(!this.value) { this.value = obj.mvalue;};
                });
    }
