jQuery Row Column Highlight on Hover
This jQuery code is used to invoke hover() on the mouseover event of the table row(tr) and table-head(TH) elements. This will execute jQuery highlight functions by changing the corresponding CSS properties.
javascript
$(document).ready(function() {
$('.table-row').hover(function() {
$(this).addClass('current-row');
}, function() {
$(this).removeClass('current-row');
});
$("th").hover(function() {
var index = $(this).index();
$("th.table-header, td").filter(":nth-child(" + (index+1) + ")").addClass("current-col");
$("th.table-header").filter(":nth-child(" + (index+1) + ")").css("background-color","#999")
}, function() {
var index = $(this).index();
$("th.table-header, td").removeClass("current-col");
$("th.table-header").filter(":nth-child(" + (index+1) + ")").css("background-color","#F5F5F5")
});
});
