a link 标签的disabled属性实现disabled/enable

由于a link是disabled属性设置成true,只是颜色变灰色但是还能提交.要想不能提交,可以删除href属性:

disable link

[html]  view plain copy

1. function disableLink(link) {  
2.     //link.disabled = true;     
3.     link.setAttribute("disabled",true);   
4.     link.removeAttribute('href');     
5. }  

enable link

[javascript]  view plain copy

1. function enableLink(link,href) {  
2.     link.setAttribute("disabled",false);     
3.     link.setAttribute("href",href);     
4. }
