javascript - 如何隔开复选框，列出和删除按钮

问题描述

我做了一个待办事项列表，所有功能都可以工作，但我不知道如何在输入和删除按钮之间放置空格，然后像复选框一样对齐删除按钮。在输入了许多输入之后，整个列表看起来就很混乱。

var inputItem = document.getElementById("inputItem");
inputItem.focus();

// adds input Item to list
function addItem(list, input) {
  var inputItem = this.inputItem;
  var list = document.getElementById(list);
  var listItem = document.createElement("li");

  // Configure the delete button
  var deleteButton = document.createElement("button");
  deleteButton.innerText = "X";
  deleteButton.addEventListener("click", function() {
    this.parentElement.style.display = 'none';
  });

  // Configure the check box
  var checkBox = document.createElement("input");
  checkBox.id = "check";
  checkBox.type = 'checkbox';
  checkBox.addEventListener('change', function() {
    labelText.style.textDecoration = checkBox.checked ? 'line-through' : 'none';
  });

  // Configure the label
  var label = document.createElement("label");
  var labelText = document.createElement("span");
  labelText.innerText = input.value;

  // Put the checkbox and label text in to the label element
  label.appendChild(checkBox);
  label.appendChild(labelText);

  // Put the label (with the checkbox inside) and the delete
  // button into the list item.
  listItem.appendChild(label);
  listItem.appendChild(deleteButton);

  list.appendChild(listItem);
  inputItem.focus();
  inputItem.select();
  return false;

}
localStorage.setItem("list", list);

localStorage.getItem("list").forEach(function(list) {
  elem.textContent = list;
});

body {
  text-align: center;
}

form {
  display: inline-block;
}

#outerDiv {
  padding: 30px;
  text-align: center;
}

#innerDiv {
  margin: auto;
  width: 200px;
  height: 100px;
}

ul {
  padding: 0;
  margin: 0;
}

ul li {
  position: relative;
  padding: 12px 8px 12px 40px;
  background: rgb(148, 160, 181);
  list-style-type: none;
  font-size: 18px;
}

#submit {
  position: absolute;
  padding: 10px 16px;
}


/* Style the input */

input {
  margin: 0;
  border: none;
  border-radius: 0;
  padding: 10px;
  float: left;
  font-size: 16px;
}

解决方案

首先给删除按钮添加一个类

deleteButton.classList.add("删除按钮");
比在 CSS 中尽可能多地使用该类设置按钮样式。

** 您还必须处理待办事项文本。如果文本较长，则样式会中断。您可以在这里应用相同的技术 - 使用 JS 添加一个类，在 CSS 中设置该类的样式。

var inputItem = document.getElementById("inputItem");
inputItem.focus();

// adds input Item to list
function addItem(list, input) {
  var inputItem = this.inputItem;
  var list = document.getElementById(list);
  var listItem = document.createElement("li");

  // Configure the delete button
  var deleteButton = document.createElement("button");
  deleteButton.classList.add("delete-button");
  deleteButton.innerText = "X";
  deleteButton.addEventListener("click", function() {
    this.parentElement.style.display = 'none';
  });

  // Configure the check box
  var checkBox = document.createElement("input");
  checkBox.id = "check";
  checkBox.type = 'checkbox';
  checkBox.addEventListener('change', function() {
    labelText.style.textDecoration = checkBox.checked ? 'line-through' : 'none';
  });

  // Configure the label
  var label = document.createElement("label");
  var labelText = document.createElement("span");
  labelText.innerText = input.value;

  // Put the checkbox and label text in to the label element
  label.appendChild(checkBox);
  label.appendChild(labelText);

  // Put the label (with the checkbox inside) and the delete
  // button into the list item.
  listItem.appendChild(label);
  listItem.appendChild(deleteButton);

  list.appendChild(listItem);
  inputItem.focus();
  inputItem.select();
  return false;

}
localStorage.setItem("list", list);

localStorage.getItem("list").forEach(function(list) {
  elem.textContent = list;
});

body {
  text-align: center;
}

form {
  display: inline-block;
}

#outerDiv {
  padding: 30px;
  text-align: center;
}

#innerDiv {
  margin: auto;
  width: 200px;
  height: 100px;
}

ul {
  padding: 0;
  margin: 0;
}

ul li {
  position: relative;
  padding: 12px 8px 12px 40px;
  background: rgb(148, 160, 181);
  list-style-type: none;
  font-size: 18px;
}

#submit {
  position: absolute;
  padding: 10px 16px;
}


/* Style the input */

input {
  margin: 0;
  border: none;
  border-radius: 0;
  padding: 10px;
  float: left;
  font-size: 16px;
}
.delete-button {
  float: right;
  border: 0;
  padding: 1px 3px 0;
  font-size: 9px;
}
