如何超链接在新选项卡中打开并携带一些变量的选择标记 - How to hyperlink a select tag which open in a new tab and carry some variables

我是PHP新手。我想在用户点击选择标签的选项标签时打开一个新标签。但我失败了。请帮帮我。

这是我的代码

echo '<select name="sector_study_data" id="sector_study_data" STYLE="width: 300px">';
echo '<option value="">[--Select Sector Study2----]</option>';
    if(is_array($sector_study ) && !empty($sector_study ))
    {
        foreach($sector_study  as $sector_study)
        {
            echo '<option value="'.$sector_study->ID.'" href="update_sector_study.php?id='.$sector_study->ID.'"
            "target="_blank"">';
            //echo '<a href="http://www.w3schools.com">$sector_study->name</a>';
            echo $sector_study->name;
            echo '</option>';
        }
    }
echo '</select>';

在这里使用jquery可以实现您的需求：

1将url添加到所有选项的数据href属性中：

echo '<select name="sector_study_data" id="sector_study_data" STYLE="width: 300px">';
echo '<option value="">[--Select Sector Study2----]</option>';
    if(is_array($sector_study ) && !empty($sector_study ))
    {
        foreach($sector_study  as $sector_study)
        {
            echo '<option value="'.$sector_study->ID.'" data-href="update_sector_study.php?id='.$sector_study->ID.'">';
            //echo '<a href="http://www.w3schools.com">$sector_study->name</a>';
            echo $sector_study->name;
            echo '</option>';
        }
    }
echo '</select>';

使用jquery:

$("#sector_study_data").change(function(){
  var href = $('option:selected', this).attr('data-href'); // get href of selected option
  window.open(href, '_blank'); // redirect to that href in new tab
})
