当检查箱被点击时,如何改变浏览Xcol2的背景色?
<table>
<tr><td>row1col1</td><td>row1col2</td><td><input class="actionItem" type="checkbox" /></td></td></tr>
<tr><td>row2col1</td><td>row2col2</td><td><input class="actionItem" type="checkbox" /></td></tr>
<tr><td>row3col1</td><td>row3col2</td><td><input class="actionItem" type="checkbox" /></td></td></tr>
</table>
$("tr :checkbox").live("click", function() {
$(this).closest("tr").css("background-color", this.checked ? "red" : "");
});
Try:
$(".actionItem").click(function() {
var highlight_td = $(this).parent().prev("td");
highlight_td.css({background-color: "#ff0"});
});
