我正在通过待办事项列表教程工作。在我尝试对其进行一些样式设置之前,它一直工作正常。我在带有“删除”类的按钮内有一个“超赞”垃圾桶图标。基本上,我取消了按钮的所有样式,因此只是垃圾图标。用户单击它,然后就可以删除待办事项列表项。我想从弹出的任务中正确对齐垃圾桶。这样做是可行的,但是每次我添加新任务时,垃圾桶都会越来越少地漂浮。
我将尝试仅发布相关代码,但是我不确定为什么会这样。我正在使用引导程序来帮助样式,并且加号圆形按钮似乎在创建任务时不会干扰它们。任何想法都很棒,谢谢大家!
function get_todos() {
var todos = new Array;
var todos_str = localStorage.getItem('todo');
if (todos_str !== null) {
todos = JSON.parse(todos_str);
}
return todos;
}
function add() {
var task = document.getElementById('task').value;
var todos = get_todos();
todos.push(task);
localStorage.setItem('todo', JSON.stringify(todos));
show();
return false;
}
//This is mostly where the remove button takes place
function remove() {
var id = this.getAttribute('id');
var todos = get_todos();
todos.splice(id, 1);
localStorage.setItem('todo', JSON.stringify(todos));
show();
return false;
}
function show() {
var todos = get_todos();
var html = '<ul>';
for(var i=0; i < todos.length; i++) {
html += '<li>' + todos[i] + '<button class="remove" id="' + i + '"><i class="fa fa-trash" aria-hidden="true"></i></button></li>';
};
html += '</ul>';
document.getElementById('todos').innerHTML = html;
var buttons = document.getElementsByClassName('remove');
for (var i=0; i < buttons.length; i++) {
buttons[i].addEventListener('click', remove);

这是因为上方的浮动元素妨碍了操作。一种避免这种情况的方法是将clear: right
或clear: both
添加到浮动元素的样式中。
.remove { /*Trash can button*/
color:#C0C0C0;
font-size:24px;
border:0;
padding:0;
background-color:transparent;
float:right;
clear:right;
}
