                </select>

我如何从这个表格中选择值？

Answer 1

根据我的评论，您试图在URL中的最后一个参数上选择当前选项。你只需要selected="selected"。试试这个：

<select name="bulan" onchange="redirect(this.value)">
    <option value="#">Pilih Bulan</option>
    <option value="<?= base_url(); ?>index.php/kalender/cari_agenda/<?= $this->uri->segment(3); ?>/01" <?php if($this->uri->segment(4) == '01') echo 'selected="selected"'; ?>>Januari</option>
    <option value="<?= base_url(); ?>index.php/kalender/cari_agenda/<?= $this->uri->segment(3); ?>/02" <?php if($this->uri->segment(4) == '02') echo 'selected="selected"'; ?>>Februari</option>
    <option value="<?= base_url(); ?>index.php/kalender/cari_agenda/<?= $this->uri->segment(3); ?>/03" <?php if($this->uri->segment(4) == '03') echo 'selected="selected"'; ?>>Maret</option>
    <option value="<?= base_url(); ?>index.php/kalender/cari_agenda/<?= $this->uri->segment(3); ?>/04" <?php if($this->uri->segment(4) == '04') echo 'selected="selected"'; ?>>April</option>
    <option value="<?= base_url(); ?>index.php/kalender/cari_agenda/<?= $this->uri->segment(3); ?>/05" <?php if($this->uri->segment(4) == '05') echo 'selected="selected"'; ?>>Mei</option>
    <option value="<?= base_url(); ?>index.php/kalender/cari_agenda/<?= $this->uri->segment(3); ?>/06" <?php if($this->uri->segment(4) == '06') echo 'selected="selected"'; ?>>Juni</option>
    <option value="<?= base_url(); ?>index.php/kalender/cari_agenda/<?= $this->uri->segment(3); ?>/07" <?php if($this->uri->segment(4) == '07') echo 'selected="selected"'; ?>>Juli</option>
    <option value="<?= base_url(); ?>index.php/kalender/cari_agenda/<?= $this->uri->segment(3); ?>/08" <?php if($this->uri->segment(4) == '08') echo 'selected="selected"'; ?>>Agustus</option>
    <option value="<?= base_url(); ?>index.php/kalender/cari_agenda/<?= $this->uri->segment(3); ?>/09" <?php if($this->uri->segment(4) == '09') echo 'selected="selected"'; ?>>September</option>
    <option value="<?= base_url(); ?>index.php/kalender/cari_agenda/<?= $this->uri->segment(3); ?>/10" <?php if($this->uri->segment(4) == '10') echo 'selected="selected"'; ?>>Oktober</option>
    <option value="<?= base_url(); ?>index.php/kalender/cari_agenda/<?= $this->uri->segment(3); ?>/11" <?php if($this->uri->segment(4) == '11') echo 'selected="selected"'; ?>>November</option>
    <option value="<?= base_url(); ?>index.php/kalender/cari_agenda/<?= $this->uri->segment(3); ?>/12" <?php if($this->uri->segment(4) == '12') echo 'selected="selected"'; ?>>Desember</option>
</select>

Answer 2

您编写的脚本运行正常。我可以假设页面上的URL或其他js代码有问题。如果您使用的是不带协议的URL（例如http：//），则可能会导致重定向问题。

如果您想获得一个类别，就像您在评论中指出的那样。然后我建议：

<script type="text/javascript">
function redirect(site){
    var category = site.split('/')[5];
    //other code goes here...
}
</script>
