javascript - 通过 'this' 进行警报

Question

我想在 div 中“找到”带有 .removeRow 类的按钮后使用alertify.js

  $(".removeRow").find("button").click(function(){
            alertify.confirm("remove this field?", function (e) {
                if (e) {
                    // user clicked "ok"
                    $(this).closest(".agrRow").remove();
                }
            });     
  });

问题是在我调用alertify之后，我失去了“this”的值。如何将“this”传递到alertify函数中？

Answer 1

$(".removeRow").find("button").click(function(){
    var temp = this;
    alertify.confirm("remove this field?", function (e) {
        if (e) {
            // user clicked "ok"
            $(temp).closest(".agrRow").remove();
        }
    });     
});
