JavaScript traverses the Element sample code in table

  This article mainly describes how JavaScript traverses the elements in a table, and the friends you need can refer to the following

     !--newszw_hzh_begin-->

For example:

 <tabl E id=tb> <tr><th> </th><th> </th><th> </th><th > </th></tr> <tr><td> </td><td> </td><td>  </td><td> </td></tr> <tr><td> </td><td>  </td><td> </td><td> </td></tr> </table> 

And in JS how to traverse assignment?
Program code

 var count=0 for (i=0, I < document.getElementById ("Tb1"). Rows.length; i++) {for (j=0; J < document.getElementById ("Tb1"). Rows (i)-cells.length;
　　　　J + +) {document.all.getElementById ("tb1"). Rows (i). Cells (j). innertext = count;
　　count++; } 

See another way to use DOM (but try not to try it out, for unknown reasons)

 <table id= "MyList" > <tr><td > A monk has water to drink. </td></tr> <tr><td> two monks fetch water and drink. </td></tr> <tr><td> three monks have no water to drink. </td></tr> </table> <script> var msg= "" Var mylist=document.getelementbyidx ("MyList") for (i=0 ; i<mylist.childnodes.length; i++) {var tr=mylist.childnodes[i]; for (j=0;j<tr.childnodes[j].length; J + +) {var td=tr.childnodes[j]; msg+=
Td.innertext;
} alert (msg); </script>
