我在使用带有jquery的元素时遇到了麻烦.我在var中构造名称,例如:

var myId = "#" + myGotId;

$(myId).attr("title", "changed");

$(myId)返回空.我希望通过id获取我的元素,但构建我的Id动态加入字符串.

由@Pointy编辑 - OP在评论中提供的附加代码:

var form = $('form#formDefaultValue');
$(':submit', form).click(function(event) {
  event.preventDefault();
  $.post(form.attr('action'), form.serialize(), function(data, status, XMLHttpRequest) {
    if (status == 'success') {
      $("#msgInformation").html("Your changes have been successfully saved.");
      jQuery("#spanDefaultValue").attr("class", "db");
      var g = indexNodeSelected;
      g = g.replace("\\", "\\\\\\\\");
      $('#'+ g).find("span").attr("class", "");
   }
