问题描述

用户点击表格的一行,我想获得(用Javascript)innerhtml,让我们说这一行的第三列。



Something如:

  document.getElementById(tblBlah)。rows [i] .columns [j] .innerHTML 

似乎不可行,我在这里或网上找不到任何东西。



任何解决方案都将非常值得赞赏(NO jQuery)

解决方案

 的document.getElementById( tblBlah)行[I] .columns [j]的.innerHTML。 

应该是:

 的document.getElementById( tblBlah)行[I] .cells [j]的.innerHTML。 

但是我明显地看到您需要的行/单元格是用户点击的行/单元格。如果是这样,最简单的方法就是将一个事件附加到表格中的单元格中:

  function alertInnerHTML(e) 
{
e = e || window.event; // IE
alert(this.innerHTML);
}

var theTbl = document.getElementById('tblBlah'); (var j = 0; j (var i = 0; i {

{
theTbl.rows [i] .cells [j] .onclick = alertInnerHTML;




$ b $ p
$ b

这使得所有表格单元都可点击,并提醒它的innerHTML 。事件对象将被传递给 alertInnerHTML 函数,其中 this 对象将是对单元格的引用被点击。事件对象提供了大量巧妙的技巧,说明如果单击单元格中存在链接时,您希望单击事件的行为方式,但我建议检查MDN和MSDN(对于window.event对象) p>

A user clicks on a row of a table, and I want to get (in Javascript) the innerhtml of let's say the 3rd column of that row.

Something like :

document.getElementById("tblBlah").rows[i].columns[j].innerHTML

doesn't seem achievable and I can't find anything here or in the net.

Any solutions would be very much appreciated ( NO jQuery )

解决方案

document.getElementById("tblBlah").rows[i].columns[j].innerHTML;

Should be:

document.getElementById("tblBlah").rows[i].cells[j].innerHTML;

But I get the distinct impression that the row/cell you need is the one clicked by the user. If so, the simplest way to achieve this would be attaching an event to the cells in your table:

function alertInnerHTML(e)
{
    e = e || window.event;//IE
    alert(this.innerHTML);
}

var theTbl = document.getElementById('tblBlah');
for(var i=0;i<theTbl.length;i++)
{
    for(var j=0;j<theTbl.rows[i].cells.length;j++)
    {
        theTbl.rows[i].cells[j].onclick = alertInnerHTML;
    }
}

That makes all table cells clickable, and alert it's innerHTML. The event object will be passed to the alertInnerHTML function, in which the this object will be a reference to the cell that was clicked. The event object offers you tons of neat tricks on how you want the click event to behave if, say, there's a link in the cell that was clicked, but I suggest checking the MDN and MSDN (for the window.event object)
