1,前导空白
IE6,IE7,IE8的innerHTML时不会保留前导空白
var div = document.createElement(‘div‘);
               div.innerHTML = "   <div></div>";
               return div.firstChild.nodeType === 3;
 }

2,tbody
IE6,IE7会为table自动添加tbody
function tbody() {
               var div = document.createElement(‘div‘);
               div.innerHTML = "<table></table>";
               return !!div.getElementsByTagName(‘tbody‘).length;
}

3,href,src,width,height
IE6,IE7的getAttribute会返回格式化href,src,width,height.
IE的getAttribute有两个参数，将第二个参数设为2，会严格返回文档设置是的参数

4,checkOn
检查复选框的默认值
function checkOn() {
               var div = document.createElement(‘div‘);
               div.innerHTML = ‘<input type="checkbox" />‘;
               var input = div.getElementsByTagName(‘input‘)[0];
               return input.value =http://www.mamicode.com/== ‘on‘;
 }

5,cloneChecked
IE复制DOM时不会复制checked属性
function cloneChecked() {
               var div = document.createElement(‘div‘);
               div.innerHTML = ‘<input type="checkbox" />‘;
               var input = div.getElementsByTagName(‘input‘)[0];
               input.checked = true;
               return input.cloneNode(true).checked;
 }

6,optSelected
测试游览器下拉框默认选中的选项的selected属性是否为true
IE和早期的safari返回false
function optSelected() {
               var select = document.createElement(‘select‘);
               var opt = select.appendChild( document.createElement(‘option‘) );
               return opt.selected;
 }

7,optDisabled
测试当禁用select时,option是否会被禁用,禁用发挥false,反之返回false
function optDisabled() {
               var select = document.createElement(‘select‘);
               var opt = select.appendChild( document.createElement(‘option‘) );
               select.disabled = true;
               return opt.disabled;
}
