一个故事板中iPhone和iPad的不同方向(Different orientation for iPhone and iPad in one storyboard)

 您可以使用jQuery的data（）方法将信息与文档本身相关联，而不是全局变量： 
 
$(".objects_list").live('click', function(event) {
    $(this).css("color", "blue");
    $(document).data("yourObjectKey", $(this));
});
 
 然后，您可以稍后轻松获取该信息： 
 
$("otherSelector").click(function() {
    var yourObject = $(document).data("yourObjectKey");
    if (yourObject != null) {
        yourObject.css("color", "red");
    }
});
 
 编辑：如果元素被销毁并在两个事件之间重新创建，该方法将无法工作。 在这种情况下，您可以存储元素的id而不是对元素本身的引用： 
 
$(".objects_list").live('click', function(event) {
    $(this).css("color", "blue");
    $(document).data("yourObjectKey", this.id);
});
 
 然后： 
 
$("otherSelector").click(function() {
    var yourObjectId = $(document).data("yourObjectKey");
    if (yourObjectId != null) {
        $("#" + yourObjectId).css("color", "red");
    }
});

Instead of a global variable, you can use jQuery's data() method to associate information with the document itself:
 
$(".objects_list").live('click', function(event) {
    $(this).css("color", "blue");
    $(document).data("yourObjectKey", $(this));
});
 
Then you can easily get that information later:
 
$("otherSelector").click(function() {
    var yourObject = $(document).data("yourObjectKey");
    if (yourObject != null) {
        yourObject.css("color", "red");
    }
});
 
EDIT: If the element is destroyed and recreated between the two events, that method won't work. In that case, you can store the element's id instead of a reference to the element itself:
 
$(".objects_list").live('click', function(event) {
    $(this).css("color", "blue");
    $(document).data("yourObjectKey", this.id);
});
 
Then:
 
$("otherSelector").click(function() {
    var yourObjectId = $(document).data("yourObjectKey");
    if (yourObjectId != null) {
        $("#" + yourObjectId).css("color", "red");
    }
});
