如何从名为"Limit"的列中提取数据(字符串)?在Javascript表中("displayTable")显示?

How do I pull data (string) from a column called "Limit" in a table ("displayTable") in Javascript?

var table = document.getElementById('displayTable');    
var rowCount = table.rows.length;    
for (var i = 1; i < rowCount - 1; i++) {    
     var row = table.rows[i]["Limit"].ToString();
     alert(row);
     ...
}

推荐答案

这是我完成用javascript阅读表格的方式.基本上，我向下钻取到行，然后能够对每一行钻取到单个单元格. 这应该给你一个主意

This is how I accomplished reading a table in javascript. Basically I drilled down into the rows and then I was able to drill down into the individual cells for each row. This should give you an idea

//gets table
var oTable = document.getElementById('myTable');

//gets rows of table
var rowLength = oTable.rows.length;

//loops through rows    
for (i = 0; i < rowLength; i++){

   //gets cells of current row
   var oCells = oTable.rows.item(i).cells;

   //gets amount of cells of current row
   var cellLength = oCells.length;

   //loops through each cell in current row
   for(var j = 0; j < cellLength; j++){
      /* get your cell info here */
      /* var cellVal = oCells.item(j).innerHTML; */
   }
}

已更新-测试脚本

<table id="myTable">
    <tr>
        <td>A1</td>
        <td>A2</td>
        <td>A3</td>
    </tr>
    <tr>
        <td>B1</td>
        <td>B2</td>
        <td>B3</td>
    </tr>
</table>
<script>
    //gets table
    var oTable = document.getElementById('myTable');

    //gets rows of table
    var rowLength = oTable.rows.length;

    //loops through rows    
    for (i = 0; i < rowLength; i++){

      //gets cells of current row  
       var oCells = oTable.rows.item(i).cells;

       //gets amount of cells of current row
       var cellLength = oCells.length;

       //loops through each cell in current row
       for(var j = 0; j < cellLength; j++){

              // get your cell info here

              var cellVal = oCells.item(j).innerHTML;
              alert(cellVal);
           }
    }
</script>
