Find last td without using Jquery

问题

I need to find the Last td of every row in a HTML table, and remove a css from that td. Can I do it without using Jquery. How?

回答1:

You can use css3 last-child property for this. Write like this:

tr td:last-child{
 color:red;
}

But it's not work in IE8 & below.

回答2:

Use CSS

td:last-child: {
  //your style here
}

Docs on CSS3 selectors here

or using traverse the DOM using JavaScript :

var mytable = document.getElementById('tableid');
var myrows = mytable.getElementsByTagName("tr");
var lastrow = myrows[myrows.length -1];
var mycells = lastrow.getElementsByTagName("td");
var lastcell = mycells[mycells.length -1];
// set CSS property here
lastcell.style.color = "red";

lastcell is your last td

Working example using JavaScript

Have you tried using CSS3 selectors? E.g

tr td:last-child
  {
    YOUR CODE HERE
  }

You could also look at using classes to show which td's are the last. But of course this isnt dynamic.

I believe there is also a normal javascript answer but im not very good at that :P

Assuming that you are not looking for css type solution

rows=document.getElementsByTagName('tr')
for (var i=0; i<rows.length; i++){
    columns=rows[i].getElementsByTagName('td');
    mytd = columns[columns.length-1];
    classname = mytd.className;
    arr = classname.split(' ');
    mytd.className = arr.filter(function(e){return e!=CLASSTOREMOVE}).join(' ');
}

For a pure JavaScript solution:

function removeCssClass(tableId, cssClass) {
    var trs = null;
    var tr = null;
    var tds = null;
    var td = null;
    var classes = [];
    var i = 0;

    trs = document.getElementById(tableId).getElementsByTagName('tr');
    tds = trs[trs.length - 1].getElementsByTagName('td');
    td = tds[tds.length - 1];
    classes = td.className.split(' ');
    for (i = 0; i < classes.length; i += 1) {
        if (classes[i] === cssClass) {
            classes.pop(i);
        }
    }
    td.className = classes.join(' ');
    return false;
}

Working fiddle.

What are you trying to do with the last TD? If you are wanting to have a border in-between each td why don't you use border-left and then you can use first-child to remove it. There might be a better approach that is more compatible with browsers.
