loop through all td elements in a table
提问by user517406
How would I loop through all the td elements in a table? I need to find the id of each td and compare it against a value. Any help would really be appreciated!

Use jQuery.eachto loop all your td's:
使用jQuery.each来循环你所有的 td：
$("td").each(function() {
var id = $(this).attr("id");
// compare id to what you want
});

var all_td_in_a_table = $("#table-id td"),
var all_td_in_a_table = $("#table-id td"),
then you can do a loop
然后你可以做一个循环

$('#tableId').find('tr').each(function () {
$(this).find("td[id^='tdId']").each(function (i, item) {
//do your task here
});
});
Or the effective one is get all the tds from table first
或者有效的方法是先从表中获取所有 tds
var totalTdsInTable = $("#table-id td");
Now loop through totalTdsInTable
现在循环遍历 totalTdsInTable
