选择框值以href

Question

I'm add multilingual functionality to my page and having trouble with a select box. 我向页面添加了多语言功能，但选择框出现了问题。 I want to change the language dynamically displayed on a page to match the chosen language in the select box. 我想更改页面上动态显示的语言，以匹配选择框中选择的语言。

This is my html code: 这是我的html代码：

<?php
include_once 'multilingual_common.php';
?>

<!DOCTYPE>

<html>
<head>
    <title>Test Form</title>
</head>
<body>
    <div id="languages">
        <select onChange="if (this.value) window.location.href=this.value">
            <option value="multilingual_test.html?lang=en">English</option>
            <option value="multilingual_test.html?lang=ko">한국어</option>
        </select>
        <a href="multilingual_test.html?lang=en">English</a>
        <a href="multilingual_test.html?lang=ko">한국어</a>
    </div>
    <ul>
        <li><?php echo $lang['CHARACTER_NAME']; ?> Rose</li>
        <li><?php echo $lang['CHARACTER_LEVEL']; ?> 40</li>
        <li><?php echo $lang['CHARACTER_SEX']; ?> female</li>
        <li><?php echo $lang['CHARACTER_SEX']; ?> none</li>
    </ul>
</body>
</html>

It works when clicking the tag but not the select box. 单击标签而不是选择框时，它可以工作。 The onChange event used in tag doesn't work. 标签中使用的onChange事件不起作用。 How should I fix this? 我该如何解决？

Answer 1

You are using a select list. 您正在使用选择列表。 Getting the value is a tad more complex. 获得价值要复杂得多。 A select list has many options . 选择列表有很多options 。 The options are an array under the this object in the onchange event. 选项是onchange事件中this对象下的数组。

The current selected index is stored in this.selectedIndex 当前选定的索引存储在this.selectedIndex

So to get a value, you need to acces the correct option in the array by the selected value 因此，要获取一个值，您需要根据所选值访问数组中的正确选项

this.options[this.selectedIndex].value

is how you get a value from a select list. 是从选择列表中获取值的方式。

To fix your code you should use instead of 要修复您的代码，您应该使用而不是

<select onChange="if (this.value) window.location.href=this.value">

you need to get the value of the option 您需要获取期权的价值

<select onChange="if (this.options[this.selectedIndex].value) window.location.href=this.options[this.selectedIndex].value">

Answer 2

try this 尝试这个

<select  onchange="location = this.options[this.selectedIndex].value;">
            <option value="multilingual_test.html?lang=en">English</option>
            <option value="multilingual_test.html?lang=ko">한국어</option>
        </select>
