FireFox不支持document.all,可以用document.getElementsByTagName("*") 代替

 

< div  class = 'view  view-case-view-all '    >    
      < div  class =   'view-content  view-content-case-view-all '   >    
        < table  border ="1"     >    
          < tr  class ="odd"     >    
            < td  class ="view-field view-field-node-title"     > 任务测试1    </ td    >    
< td  class ="view-field view-field-workflow-states-state"     > 执行中    </ td    >    
          </ tr    >    
          < tr  class ="even"     >    
            < td  class ="view-field view-field-node-title"     > 任务测试2    </ td    >    
< td  class ="view-field view-field-workflow-states-state"     > 完成    </ td    >    
          </ tr    >

          </ tr    >    
        </ table    >    
      </ div    >    
</ div    >
