使用dropdownlist绑定数据的步骤如下:
<select id="myDropdownList"></select>
var dropdownList = document.getElementById("myDropdownList");
var data = ["选项1", "选项2", "选项3"];
for (var i = 0; i < data.length; i++) {
var option = document.createElement("option");
option.text = data[i];
dropdownList.add(option);
}
完整的示例代码如下:
<select id="myDropdownList"></select>
<script>
var dropdownList = document.getElementById("myDropdownList");
var data = ["选项1", "选项2", "选项3"];
for (var i = 0; i < data.length; i++) {
var option = document.createElement("option");
option.text = data[i];
dropdownList.add(option);
}
</script>
这样就完成了使用dropdownlist绑定数据的操作。
