I'm creating a movie DB app with vue and I'm trying to output an image source that is being fetched from an API. For some reason the output of the src is not being rendered as it should in the app. It prints the string {{movie.Poster}}.
I'm obviously not using v-bind in the right way. So any ideas on how I would print the path to the poster in the right way?
<template>
<div class="my-10">
<h2 class="text-bold">{{ movie.Title }}</h2>
<img v-bind:src="'{{movie.Poster}}'"/>
</div>
</template>
You need to use
<img :src="movie.Poster"/>
because {{ .. }} is template literals. So it output a string.

I want to pass information (link) form Object, and give it as the src to image. Somehow tag doesn't see it. Even though it console log proper link and the link is working.
Object
setup() {
const state = reactive({
flashcardObject: {
linkToGraphic: 'https://static.fajnyzwierzak.pl/media/uploads/media_image/auto/entry-content/785/mobile/dog-niemiecki.jpg'}
})
return{
state
}
}
Where is the bug
<template>
<div>
<div class="ViewFlashcards">
<div class="image_div">
<img class="picture" src="{{state.flashcardObject.linkToGraphic}}"/>
</div>
</div>
</div>
</template>
Thank you for your help!
Use v-bind, like so:
<img v-bind:src="state.flashcardObject.linkToGraphic" class="picture"/>
Full code:
<template>
<div>
<div class="ViewFlashcards">
<div class="image_div">
<img class="picture" v-bind:src="state.flashcardObject.linkToGraphic"/>
</div>
</div>
</div>
</template>
v-bind allows you to bind an (HTML) attribute to a data property or just some JS code. In this case you just pass along your image URL to the src attribute of the <image>.
Note that mustache syntax, {{ something }}, does not work in HTML attributes; it only will work within elements, like <p>{{ something }}</p>.
Also, note that instead of v-bind:attribute, you can omit the v-bind part and just keep the colon, like so: :attribute. This makes it easier to bind attributes.
For more info and examples see the docs
You should require it and use : to bind the image src to the required path if the image is stored in the app :
<img class="picture" :src="require(state.flashcardObject.linkToGraphic)"/>
or :
<img class="picture" :src="state.flashcardObject.linkToGraphic"/>
if the image is hosted online.
List item
<ul>
<li>language</li>
< v-if= "tree()"> //which tag I may use or any other process
<li>home</li>
<li>about</li>
<>
< v-else> //which tag I may use or any other process
<li>accounts</li>
<li>listing</li>
<>
</ul>'
In the V-if which html tag i may use or any other vue.js process to work with this.
You can use template:
<template v-if="condition">
</template>
<template v-else>
</template>
Template will not be rendered in the browser. But it will parse the contents inside of this to the html.
you can sometimes use the <slot> element to make what you want. Have a look at the slot documentation here
I am having trouble displaying images in my Vue CLI project.
Here is what I have going on. This vue file accesses a json file with a few references to the individual Eyewear objects, all that works. I have references to the image I am trying to access in the json file. And with the current code, I can see the correct image reference in the browser, but it does not load the image. Is it something to do with webpack or another loader needing to load the image file?
<template>
<div>
<h1 id='callout'>Select Your Eyewear</h1>
<div id='item' v-for='item in items' :key=item.id>
<img :src='`..${item.images.frontal}`' alt='eyeware' />
<ul id='itemLIist'>
<li >
{{ item.brand }}
</li>
<li>
{{ item.name }}
</li>
</ul>
</div>
</div>
</template>
<script>
import items from "../assets/eyewear.json";
export default {
name: "ItemList",
data: function() {
return {
items: items.eyewear
};
}
};
</script>
<style scoped>
</style>
I don't know this works for you or not. But in my case providing the full path of the image works for me. in your screenshot reference starting from "../assets" instead of that try something "src/assets" (Full path with out dots)
and for make this simple, first just try to hard code full path src to a image tag and see whether it's working or not.
and let me know if this works for you. =)
Condider the following snippet:
<template v-if="tryIsMobile" >
<div class='device device-mobile-portrait' :class="deviceClass">
<div class="device-scroller-container">
<div class='device-scroller'>
<img id='tryit-img-mobile' :src="srcUrlMobile" v-on:load="onImgLoad" v-on:error="onImgError"/>
</div>
</div>
</div>
</template>
<template v-else>
<div class='device device-tablet-landscape' :class="deviceClass" >
<div class="device-scroller-container">
<div class='device-scroller'>
<img id='tryit-img-tablet' :src="srcUrlTablet" v-on:load="onImgLoad" v-on:error="onImgError"/>
</div>
</div>
</div>
</template>
This code conditionally renders one of the two images. Some user action results in the actual shown image to be toggled.
What I'm seeing is the following: When toggling from say, tryit-img-mobile to tryit-img-tablet, the image loaded as part of tryit-img-mobile will get displayed with different dimensions instantly. However, during the time the image loads it's new source :src="srcUrlTablet", the image with src :src="srcUrlMobile" still displays.
This is probably due to Vue using the same img-tag for both the templates. How can I prevent Vue from doing this, and instead use seperate img-tags?
In cases such as this, Vue uses a special key attribute that tells it not to reuse the same element. Give each element this attribute with a unique value, and Vue will no longer reuse the same element:
<div v-if="tryIsMobile"
class="device device-mobile-portrait"
:class="deviceClass"
key="mobile"
>
...
</div>
<div v-else
class="device device-tablet-landscape"
:class="deviceClass"
key="tablet"
>
...
</div>
I am using Selenium and Java to write a test, I need to check if a web element does not have another web element inside it, for example:
<div><span>bla bla</span></div>
<div><g></g></div>
<div><li></li></div>
I need to select the div tags which does not have <span> inside them, so do we have something like:
//div[not(.//span[text()='bla bla'])]
Please do not tell me how to do it in other ways as I already know, I am just wondering if I can do it in a way like the one above.
Your XPath should've done what you wanted. It will select <div> element that doesn't contain, either direct child or nested, span element with text equals "bla bla". See the demo online : http://www.xpathtester.com/xpath/be01362aa9bb1385da6dcf819cf69376
input :
<div>
<div>
<span>bla bla</span>
</div>
<div>
<g/>
</div>
<div>
<li/>
</div>
</div>
output :
<div>
<g/>
</div>
<div>
<li/>
</div>
