[英]how to set dynamic style in select option in vue js
<select v-model="selectcurrency"
@change="[get(),ready(),setcookie()]"
class="selectpicker"
data-live-search="true"
data-width="120px"
style="width: 80px;">
<option v-for="item in currency" :value="item"
:style="color:'red'" //this style>
@{{item.symbol}} -- @{{ item.name }}
</option>
</select>
I need the option
tag with item.count
where it will color it black if item.count > 0
and color it red if item.count < 0
.我需要带有
item.count
的option
标签,如果item.count > 0
它将其着色为黑色,如果item.count < 0
将其着色为红色。
Then an image in option
tag with item.image
but this doesn't work然后是带有
item.image
的option
标签中的图像,但这不起作用
data-subtext="<img src='item.icon' class='img img-circle img-thumbnail'>"
You can use Class And Style Bindings with Ternary Operator您可以将类和样式绑定与三元运算符一起使用
In your situation:在你的情况下:
<option v-for="item in currency" :value="item" :style="{ color: item.count > 0 ? 'red' : 'black'" //use like this> @{{item.symbol}} -- @{{ item.name }} </option>
