如何从 Javascript 中的表(“displayTable”)中名为“Limit”的列中提取数据(字符串)?
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);
...
}
这就是我在 javascript 中完成读取表格的方法。基本上,我深入到行,然后我能够深入到每行的各个单元格。
这应该给你一个想法
//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; */
}
}
更新的脚本
//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;
console.log(cellVal);
}
}
<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>
