IE6-IE9 tbody innerHTML cannot be assigned, reproduce the code as follows

?
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 <!DOCTYPE html>              <meta charset="utf-8"/>         <title>IE6-IE9中tbody的innerHTML不能复制bug</title>          <body style="height:3000px">         <table>             <tbody>                 <tr><td>aaa</td></tr>             </tbody>         </table>         <p>             <button id="btn1">GET</button><button id="btn2">SET</button>         </p>         <script>             var tbody = document.getElementsByTagName(‘tbody‘)[0]             function setTbody() {                 tbody.innerHTML = ‘<tr><td>bbb</td></tr>‘             }             function getTbody() {                 alert(tbody.innerHTML)             }             btn1.onclick = function() {                 getTbody()             }             btn2.onclick = function() {                 setTbody()             }         </script>     </body>

Two buttons, the first to get Tbody's innerHTML, and the second to set the Tbody innerHTML.

Obtained when all browsers pop up the TR string, but the settings ie6-9 not support, and error,

You can use the feature to determine whether the browser supports TBODY innerHTML setting values

?
1 2 3 4 5 6 7 8 9 10 11 12 13 var isupportTbodyInnerHTML = function () {     var table = document.createElement(‘table‘)     var tbody = document.createElement(‘tbody‘)     table.appendChild(tbody)     var boo = true     try{         tbody.innerHTML = ‘<tr></tr>‘     } catch(e) {         boo = false     }     return boo }() alert(isupportTbodyInnerHTML)

For IE6-IE9 if you want to set tbody innerHTML, you can use the following workaround

?
1 2 3 4 5 6 7 8 function setTBodyInnerHTML(tbody, html) {     var div = document.createElement(‘div‘)     div.innerHTML = ‘<table>‘ + html + ‘</table>‘     while(tbody.firstChild) {         tbody.removeChild(tbody.firstChild)     }     tbody.appendChild(div.firstChild.firstChild) }

Use a div to include a table, then delete all the elements in the tbody, and finally add the first element of the first element of the div to Tbody, which is div>table>tr.

Of course there is a more streamlined version, which is replaced directly by the ReplaceChild method

?
1 2 3) 4 5 function setTBodyInnerHTML(tbody, html) {     var div = document.createElement(‘div‘)     div.innerHTML = ‘<table>‘ + html + ‘</table>‘     tbody.parentNode.replaceChild(div.firstChild.firstChild, tbody)}

The innerHTML of Col, Colgroup, frameset, HTML, head, style, table, TFOOT, THead, title, and TR are read-only (IE6-IE9) from the record on MSDN.

TheInnerHTMLProperty was read-only on theCol,Colgroup,FrameSet,HTML,Head,style,Table,TBody,TFoot,THead,title, andTRObjects.

you can change the value of the < Span style= "Background-color:rgb (192, 192, 192); > title  element using The  Document . Title property.

The contents of the table, tFoot, tHead, and tr elements, use the table Obje CT model described in Building Tables dynamically. However, to change the content of a particular cells, you can use InnerHTML.
