Question

有没有办法将最后两行代码格式组合成一个？

str = "1, 2, 3, 4, 5, "

str = str:gsub("%p", {[","] = " >" }) -- replaces ',' with '>'
str = string.sub(str, 1, #str - 2) --removes last whitespace + comma

Answer 1

 $(".tile a").click(function () {
     $(this).closest("div").toggleClass("selected_tile");
     //use varible!! no need to see (this).parent.parent.parent so many times XD
     var grandParent = $(this).parent().parent();
     //Check if it already has an "old class"
     if ((grandParent.attr("data-old-class"))&&grandParent.attr("data-old-class") !== '') {
         grandParent.removeClass("col-md-12").addClass(grandParent.attr("data-old-class"));
         //remove the old class (its more generic than toggle)
         grandParent.attr("data-old-class","");
     } else {
         grandParent.attr("data-old-class", grandParent.attr("class"));
         grandParent.attr("class","");
         grandParent.addClass("col-md-12");
     }
 });

这将做你想做的事。

但是，Egor的优雅更为优雅：

str = "1, 2, 3, 4, 5, "
str = str:sub(1, #str-2):gsub("%p", {[","] = " >" })

将这两个lua格式行合并为一个
