根據結果​​使用javascript更改p的背景色

Question

我需要在ap標簽中更改結果的背景色，如果變量的結果>>1。我想這可以通過if語句來完成？ 這是我正在使用的代碼：

const todos = [{
  text: 'Order airline tickets',
  completed: false
},{
  text: 'Vaccine appointment',
  completed: true
}, {
  text: 'Order Visa',
  completed: true
}, {
  text: 'Book hotell',
  completed: false
}, {
  text: 'Book taxi to airport',
  completed: true
}]

const filters = {
  searchText: ''
}

const renderTodos = function (todos, filters) {

  //use filter method for the title search string and save it to filters variable
    const filteredTodos = todos.filter(function (todo) {
        return todo.text.toLowerCase().includes(filters.searchText.toLowerCase())
    })

    const notDone = filteredTodos.filter(function (todo) {
      return !todo.completed
    })

    //Empty the div containg the result, this has to be between filter and the display of the result
    document.querySelector('#todos').innerHTML = ''

    const summary = document.createElement('h4')
    summary.textContent = `You found ${notDone.length} hits on this search that are not complete`
    document.querySelector('#todos').appendChild(summary)



    //loop through note object, create a p tag for the title searched and append to the div
    filteredTodos.forEach(function (todo) {
        const noteEl = document.createElement('p')
        noteEl.textContent = todo.text
        document.querySelector('#todos').appendChild(noteEl)

    })
    elem = document.createElement("hr")
    document.querySelector('#todos').appendChild(elem)
}

document.querySelector('#search-todo').addEventListener('input', function (e) {
  filters.searchText = e.target.value
  renderTodos(todos, filters)
})

因此，如果我要附加到我的#todos div的p標簽中也有！todo.completed，則搜索的結果是，只有那些p標簽應具有ap的黃色背景色。

謝謝

只需在forEach循環內添加以下if語句：

if (!todo.completed) {
    noteEl.style.backgroundColor = "yellow";
}

完整的循環應如下所示：

filteredTodos.forEach(function (todo) {
    const noteEl = document.createElement('p');
    noteEl.textContent = todo.text;
    if (!todo.completed) {
        noteEl.style.backgroundColor = "yellow";
    }
    document.querySelector('#todos').appendChild(noteEl);
})
