sapna如果我的回答对你有好处，可以随时接受，如果不是，请stat你需要什么更多 –

同样的问题被问here，答案仅仅是

ddl.options[i] = theOption;

此代码示例展示了如何变量添加到下拉：

var ddl = document.getElementById('myDropdown'); 
var theOption = new Option; 
var x; 
var i; 

for(i = 0; i < 999; i++) { 
x = i + 1; 
theOption.text = x; 
theOption.value = x; 
ddl.options[i] = theOption; 
}

如果你编辑你的问题，所以我们会知道什么是下拉列表名称和需要的值，然后我可以帮助你更多
