Question

我正在测试输入上的：focus ，以便在选中时将其边框更改为绿色。显然，它似乎不起作用。我尝试检查拼写错误，但没有找到任何错别字。（我是发展世界的新手）我正在尝试做一个待办事项应用程序，该应用程序的顶部具有一个输入区域，用于添加更多任务。我的目标是使该区域在选中时具有绿色边框，但似乎不起作用。

$("ul").on("click","li",function(){
    $(this).toggleClass("completed");
});

$("ul").on("click","span",function(event){
    $(this).parent().fadeOut(500,function(){
        $(this).remove();
    });
    event.stopPropagation();
});

$("input[type='text']").keypress(function(event){
    if (event.which == 13) {
        let toDo = $(this).val();
        $(this).val("");
        $("ul").append("<li><span>X</span>   " + toDo + "</li>"); 
    }
});

#container {
    border: 2px solid gray;
    width: 360px;
    margin: 0 auto;
    border: none;
    background-color: #f7f7f7;
}
ul{
    list-style: none;
    padding-left: 0px;
}

.completed {
    color: gray;
    text-decoration: line-through;
}

h1 {
    background-color: #2980b9;
    color: white;
    margin: 0;
    padding: 10px 20px;
    font-size: 24px;
    font-weight: normal;
    text-transform: uppercase;
}

li {
    height: 40px;
    line-height: 40px;
    color: #666666;
    background-color: #fff;
}

li:nth-child(2n) {
    background-color: #f7f7f7;
}

input {
    font-size: 18px;
    color: #2980b9;
    width: 315.89px;
    padding: 13px 20px 13px 20px;

}

input:focus() {
    background-color: #fff;
    border: 3px solid #0fff2d;
    outline: none;
}

在CSS中，您切勿添加def is_same(self, obj): excluded_keys = 'timestamp', 'creator_id' # creater_id is one foreign key ins table return _is_same(self, obj, excluded_keys) def _is_same(obj1, obj2, excluded_keys): d1, d2 = obj1.__dict__, obj2.__dict__ for k, v in d1.items(): # print('check key: ' + k) if k in excluded_keys or k in ['_state', '_django_cleanup_original_cache']: # _state make difference so automatically exclude it # print(k + ' is in excluded keys') continue if v != d2[k]: # print('value in not equal in second object') return False else: # print('it is same') continue # print('all keys checked, so both object is same') return True：
