Aurelia-在下拉菜单中设置默认值

Question

I have a drop-down which is populated from a JavaScript array. 我有一个从JavaScript数组填充的下拉菜单。

let a = [90, 95, 99];

When I bind this array in the HTML as follows, the initial value is set to 90. 当我按如下所示在HTML中绑定此数组时，初始值设置为90。

<select>
    <option repeat.for="i of a">${i}</option>
</select>

But I need to show '95' as the default value. 但是我需要显示“ 95”作为默认值。 So how can I achieve this? 那么我该如何实现呢？

You can bind the value of the select to a certain value, which it will take as default. 您可以将select的值绑定到某个值，该值将作为默认值。

let a = [90, 95, 99];
let selectedValue = 95;

Html: HTML：

<select value.bind="selectedValue">
    <option repeat.for="i of a">${i}</option>
</select>
