Vue.js数据绑定风格backgroundImage不起作用 [英] Vue.js data-bind style backgroundImage not working
问题描述
我试图在一个元素中绑定图像的src,但它似乎不起作用。我得到一个Invalid expression。Generated function body:{backgroundImage:{url(image)}。 文档说要使用'Kebab-case'或'camel-case'。
< div class =circularv-bind:style ={backgroundImage:{url(image)}>< / div>
这里是一个小提琴: https:/ /jsfiddle.net/0dw9923f/2/
问题是, backgroundImage
需要是这样的字符串:
< div class =circularv -bind:style ={backgroundImage:'url('+ image +')'}>< / div>
下面是一个简单的小提琴: https://jsfiddle.net/89af0se9/1/
Re:关于kebab-case的评论,这是你如何做到这一点:
< div class =circularv-bind:style ={ background-image':'url('+ image +')'}>< / div>
换句话说, v-bind:style
只是一个简单的Javascript对象,遵循相同的规则。
I'm trying to bind the src of an image in an element, but it doesn't seem to work. I'm getting an "Invalid expression. Generated function body: { backgroundImage:{ url(image) }".
The documentation says to use either 'Kebab-case' or 'camel-case'.
<div class="circular" v-bind:style="{ backgroundImage: { url(image) }"></div>
Heres a fiddle: https://jsfiddle.net/0dw9923f/2/
The issue is that the value for backgroundImage
needs to be a string like this:
<div class="circular" v-bind:style="{ backgroundImage: 'url(' + image + ')' }"></div>
Here's a simplified fiddle that's working: https://jsfiddle.net/89af0se9/1/
Re: the comment below about kebab-case, this is how you can do that:
<div class="circular" v-bind:style="{ 'background-image': 'url(' + image + ')' }"></div>
In other words, the value for v-bind:style
is just a plain Javascript object and follows the same rules.
