Javascript:根据其内容选择选项 [英] Javascript: Select option based on its contents

问题描述

基本上是这样，但是使用纯JavaScript:
如何使用Nokogiri根据选择标签的内容获取选择标签的值"

Basically this, but in pure javascript:
How to get 'value' of select tag based on content of select tag, using Nokogiri

我有一个包含许多国家/地区的选择列表，我希望能够根据<option>标记之间的内容选择一个.

I have a select list with a lot of countries/states, and I want to be able to select one based on what is between the <option> tags.

<option value="4783">Argentina</option>

(我知道我可以使用该值，但是每个值都是一个随机的数字网格，因此我必须收集每个单独的值-不经济)

(I know I could use the value, but each one is a random mesh of numbers, so I would have to collect each individual one - not economical)

推荐答案

这有点痛苦，但是使用纯JavaScript:

It is a bit painful, but in pure JavaScript:

for(var i=0,sL=mySelObj.length;i<sL;i++){
  if(mySelObj.options[i].text == myValue){
    mySelObj.selectedIndex = i;
    break;
  }
}
