javascript - 如何对选定的组合框进行操作

Question

Hi, i want to use search by id and search by date

<select id="menu">
    <option value="<?=site_url('web/execute_search')?>">By Id</a></option>
    <option value="<?=site_url('web/execute_searchs')?>">By Date</a></option>
    </select>
    <input type="text" name="search" />
    <input type="submit" value="Submit" />

我有组合框，当我选择按 id 搜索并提交时，它将转到 Controller ('web/execute_search') ，然后如果我选择日期并提交，则转到 Controller ('web/execute_search')。

Answer 1

试试这个代码:

<select id="menu" onchange="option()">
    <option value="1" content="1">By Id</a></option>
    <option value="2" content="2">By Date</a></option>
    </select>

    <input type="text" name="search" />
    <input type="submit" value="Submit" />

然后是 JavaScript:

<script>function option(){
var x = document.getElementById("menu").value;
if (x==1){
    window.location.href = "execute_search";
}
if (x==2){
window.location.href = "execute_searchs";
}}</script>
