Was*_*ikh 4 html javascript jquery
我有以下结构的表

每当用户单击支票簿并单击链接"比较差异"表列时,应突出显示值是否不同.用户可以选择两个,一旦用户选择三个中的两个(或三个以上),其他行将隐藏,仅显示比较行.
编辑:如果该列中的任何值不同,我如何将类添加到colgroup> col?或者我如何添加所选行的类/高亮div与td相比?
jQuery(document).ready(function() {
$("#compareme").click(function() {
//get all checkboxes that are not selected
var not_selected = $("input:not(:checked)");
//get all checkboxes that are selected
var selected = $("input:checked");
if($(selected).length < 2) {
//you need more than 1 for comparison
alert("please select more than 1 product")
} else {
//hide the not selected ones
$(not_selected).closest("tr").hide();
}
//loop through your columns
for(var i = 1; i < 5; i++) {
var prev = null;
$.each($(selected), function() {
var curr = $(this).closest("tr").find("td").eq(i).text();
//if at least one value is different highlight the column
if(curr !== prev && prev !== null) {
$("col").eq(i).addClass("highlight");
}
prev = curr;
})
}
})
});
