html选择列表 - 通过传递变量获取文本值? [英] html select list - get text value by passing in a variable?
问题描述
我有一个显示列表语言的选择列表。
< select name =language_codeid =id_language_code >
< option value =ar>阿拉伯语 - العربية< / option>
< option value =bg>保加利亚语 - Български< / option>
< option value =zh-CN>中文(简体) - 中文(简体)< / option>
< option value =enselected =selected>英语(美国)< / option>
< option value =fr-CA>法语(加拿大) - français(加拿大)< / option>
< / select>
我可以使用所选值的文字值以下代码[从上面的选择列表中返回英语(美国)]:
$('#id_language_code option:selected')。 text()
如果我传递选项值' bg'作为一个变量,当选择的值仍然是英语(美国)? 这意味着返回的值将是保加利亚 - Български选择的值仍然是英语(美国)。 我已经搜索了Google和SO以获得答案,但无法找到答案,所以我认为这是不像我第一次想到的那样容易! 这是一个如何使用CSS选择器来查询 下面是一个工作示例 I have a select list that displays a list languages. I am able to get the text value of the selected value using the following code [returns English (US) from the above select list]: How can I get the text value if I pass the option value of 'bg' as a variable when the selected value is still English (US)? This means that the value returned would be "Bulgarian - Български" when the selected value is still "English (US)". I have searched Google and SO for an answer, but was unable to find one, so I am thinking that this is not as easy as I 1st thought it was! Here is an example of how you can use CSS selectors to query the Here is a working example
