如果你有多个输入框，并希望进行联合精准搜索，可以通过组合多个输入框的值来过滤数据。在JavaScript中，常见的做法是先收集每个输入框的值，然后使用这些值过滤数据。

示例：多个输入框联合精准搜索

假设有多个输入框用于过滤不同的属性（例如姓名、年龄和城市），你可以使用下面的代码来实现联合精准搜索：

<input type="text" id="nameSearch" placeholder="Search by name">
<input type="number" id="ageSearch" placeholder="Search by age">
<input type="text" id="citySearch" placeholder="Search by city"><button onclick="searchData()">Search</button><ul id="results"></ul><script>
const data = [{ id: 1, name: 'John', age: 30, city: 'New York' },{ id: 2, name: 'Jane', age: 25, city: 'Los Angeles' },{ id: 3, name: 'Mike', age: 35, city: 'Chicago' },{ id: 4, name: 'Sara', age: 28, city: 'San Francisco' },
];function searchData() {const nameTerm = document.getElementById('nameSearch').value.toLowerCase();const ageTerm = document.getElementById('ageSearch').value;const cityTerm = document.getElementById('citySearch').value.toLowerCase();// 联合过滤const filteredData = data.filter(item => {return (!nameTerm || item.name.toLowerCase().includes(nameTerm)) &&(!ageTerm || item.age == ageTerm) &&(!cityTerm || item.city.toLowerCase().includes(cityTerm));});displayResults(filteredData);
}function displayResults(results) {const resultsContainer = document.getElementById('results');resultsContainer.innerHTML = '';results.forEach(item => {const li = document.createElement('li');li.textContent = `${item.name}, ${item.age}, ${item.city}`;resultsContainer.appendChild(li);});
}
</script>
