使用点表示法的 JavaScript 对象错误

Question

$(document.body).on("click",'.sub-unfollow', function(){
  var unfollow_tag = {element:"",un:"",type:"",text:""};
  var unfollow_tag.element = $(this).parents("li");
  var unfollow_tag.un = $(this).parents("li").attr("data-un");
  var unfollow_tag.type = $(this).parents("li").attr("data-type");
  var unfollow_tag.text = $(this).parents("li").text();
  alert(unfollow_tag.text);
});

Getting an error with this seemingly basic object setup. Any ideas?

Answer 1

You should remove var after once declaring unfollow_tag , it redeclares it instead of trying to access a property.

$(document).on("click",'.sub-unfollow', function(){
  var unfollow_tag = {};
  unfollow_tag.element = $(this).parents("li");
  unfollow_tag.un = $(this).parents("li").attr("data-un");
  unfollow_tag.type = $(this).parents("li").attr("data-type");
  unfollow_tag.text = $(this).parents("li").text();
  alert(unfollow_tag.text);
});
