html下拉菜单
。该怎么写代码?
您可以使用以下代码:
```
<select onchange="myFunction()">
<option value="path_forecast2020">Option 1</option>
<option value="path_forecast2021">Option 2</option>
</select>
<script>
function myFunction() {
var selectedOption = document.querySelector('select').value;
if (selectedOption === 'path_forecast2020') {
path_forecast2020();
} else if (selectedOption === 'path_forecast2021') {
path_forecast2021();
}
}
</script>
```
请根据您实际的情况修改函数名和选项值。这段代码会在下拉菜单选项改变时调用 `myFunction()` 函数,根据所选的选项值调用相应的功能函数。
