当然可以帮你写一个二级联动页面,并确保画面美观、布局整齐、尺寸合适。以下是一个简单的示例代码,你可以根据你的需求进行修改和扩展:
```html
<!DOCTYPE html>
<html>
<head>
<title>二级联动页面</title>
<style>
body {
font-family: Arial, sans-serif;
}
.container {
max-width: 600px;
margin: 0 auto;
padding: 20px;
}
.select-container {
display: flex;
justify-content: space-between;
align-items: center;
margin-bottom: 20px;
}
.select-container select {
width: 200px;
padding: 10px;
font-size: 16px;
}
.selected-item {
margin-bottom: 10px;
font-size: 18px;
font-weight: bold;
}
</style>
</head>
<body>
<div class="container">
<h1>二级联动页面</h1>
<div class="select-container">
<select id="firm-select">
<option value="">请选择事务所</option>
<option value="1">事务所1</option>
<option value="2">事务所2</option>
<option value="3">事务所3</option>
</select>
<select id="department-select" disabled>
<option value="">请选择部门</option>
</select>
</div>
<div class="selected-item" id="selected-item"></div>
<script>
const firmSelect = document.getElementById('firm-select');
const departmentSelect = document.getElementById('department-select');
const selectedItem = document.getElementById('selected-item');
firmSelect.addEventListener('change', function() {
const selectedFirm = this.value;
if (selectedFirm) {
departmentSelect.innerHTML = '';
const departments = getDepartments(selectedFirm);
departments.forEach(function(department) {
const option = document.createElement('option');
option.value = department.id;
option.textContent = department.name;
departmentSelect.appendChild(option);
});
departmentSelect.disabled = false;
} else {
departmentSelect.innerHTML = '<option value="">请选择部门</option>';
departmentSelect.disabled = true;
}
selectedItem.textContent = '';
});
departmentSelect.addEventListener('change', function() {
const selectedDepartment = this.options[this.selectedIndex];
if (selectedDepartment.value) {
selectedItem.textContent = selectedDepartment.text;
} else {
selectedItem.textContent = '';
}
});
// 模拟获取部门数据
function getDepartments(firmId) {
// 这里可以根据事务所ID获取对应的部门数据,暂时用静态数据代替
const departmentsData = {
1: [
{ id: 1, name: '部门1' },
{ id: 2, name: '部门2' },
{ id: 3, name: '部门3' }
],
2: [
{ id: 4, name: '部门4' },
{ id: 5, name: '部门5' },
{ id: 6, name: '部门6' }
],
3: [
{ id: 7, name: '部门7' },
{ id: 8, name: '部门8' },
{ id: 9, name: '部门9' }
]
};
return departmentsData[firmId] || [];
}
</script>
</div>
</body>
</html>
```
这段代码创建了一个二级联动页面,你可以选择一个事务所,然后根据选择的事务所加载对应的部门选项。选择的内容会显示在最上面的输入框中。
这个示例使用了简单的CSS样式,使页面布局整齐、尺寸合适。你可以根据需要自定义样式,添加更多的选项或者级联关系。希望这个示例对你有帮助!如果有任何问题,请随时提问。
