按钮值不会更改

带有类dropbtn的按钮的按钮值不会改变。只要将鼠标悬停在按钮上并单击某个区域，标准值“选择区域”就会更改为您单击的区域。

下面的代码片段（对于锚点中的？link = NA的JSFiddle原因不起作用。

我需要这些href是当前的？link = region。因为我需要在将来对其进行特定的api搜索。

    var region = e.target;
    regionButton.text(region.text).val(region.text);

改变这个：

$(regionList).on('click', function(e){
    var region = e.target;
    regionButton.text(region.text).val(region.text);
  });

要

$('.region_dropdown_content a').on('click', function(e){
        var region = $(this).text();
        regionButton.text(region );
});

输入类型按钮的值实际上是按钮中的文本。 

regionButton.val(region.text);

答案 2 :(得分：0)

我认为你应该拿出硬编码的“选择区域”＆＃39;对于按钮，只需将其设置为您的JavaScript代码中的默认值。目前它似乎暂时改变你的价值，然后重新加载并返回硬编码值。

答案 3 :(得分：0)

在你的javascript中，使用e.preventDefault（）;你的代码如下：

    phonegap -v
