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>
