input placeholder属性IE、360浏览器兼容性问题

效果:http://hovertree.com/texiao/jquery/43/

效果二:http://hovertree.com/texiao/jquery/43/1/

请在IE中体验。

1、创建JS文件:jquery.JPlaceholder.js

js代码如下:

/*
 * jQuery placeholder, fix for IE6,7,8,9
* hovertree.com
 */
var JPlaceHolder = {
    //检测
    _check : function(){
        return 'placeholder' in document.createElement('input');
    },
    //初始化
    init : function(){
        if(!this._check()){
            this.fix();
        }
    },
    //修复 何问起
    fix : function(){
        jQuery(':input[placeholder]').each(function(index, element) {
            var self = $(this), txt = self.attr('placeholder');
            self.wrap($('<div></div>').css({position:'relative', zoom:'1', border:'none', background:'none', padding:'none', margin:'none'}));
            var pos = self.position(), h = self.outerHeight(true), paddingleft = self.css('padding-left');
            var holder = $('<span></span>').text(txt).css({position:'absolute', left:pos.left, top:pos.top, height:h, lienHeight:h, paddingLeft:paddingleft, color:'#aaa'}).appendTo(self.parent());
            self.focusin(function(e) {
                holder.hide();
            }).focusout(function(e) {
                if(!self.val()){
                    holder.show();
                }
            });
            holder.click(function(e) {
                holder.hide();
                self.focus();
            });
        });
    }
};
//执行 
jQuery(function(){
    JPlaceHolder.init();    
});

2、页面中使用方法如下:

<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>jQuery JPlaceholder Demo - 何问起</title>
<script src="http://hovertree.com/ziyuan/jquery/jquery-1.8.3.min.js"></script>
<script src="http://hovertree.com/texiao/jquery/43/jquery.JPlaceholder.js"></script>
</head>
 
<body>
<form>
<div>
  <ul>
    <li>
      <input type="text" name="username" placeholder="用户名">
    </li>
    <li>
      <input type="password" name="username" placeholder="密码">
    </li>
    <li>
      <button type="button">登录</button>
    </li>
  </ul>
</div>
</form>
<a href="http://hovertree.com/h/bjaf/ww7ek8wn.htm">参考</a>
</body>
</html>

实践是检验真理的唯一标准,希望能帮助到大家。
