Given the next v-for:
<div class="container-fluid" id="networdapp" style="display:none;">
<div class="row" >
<div v-for="result in results" class="col-sm-6" >
<div class="card m-3 h-240 bg-light" >
<div class="card-header text-center" > {{ result.title }} </div>
<div class="card-body" style="height:200px" >
<p class="card-text" v-html="result.prevDesc"></p>
</div>
<div class="card-footer bg-transparent border-info">
<a href="/details" class="btn btn-info" @click="getData(result)" >Details</a>
</div>
</div>
</div>
</div>
</div>
And the next Vue.js script:
<script type="text/javascript">
const vm = new Vue({
el: '#networdapp',
data: {
results:[]
},
methods: {
getData: function(result){
window.alert($(this).parents("#networdapp").find(".card-header.text-center").outerHTML);
window.alert(document.getElementsByClassName("card-header").outerHTML);
window.alert(result.outerHTML);
}
},
mounted() {
axios.get('/getJson')
.then(response => {
this.results = response.data;
})
.catch( e => {
console.log(e);
});
}
});
</script>
I want to get data from a specific iteration,let's say if I click the "Details" button of the 3rd div from the v-for I want to get the {{result.title }} data from the 3rd for.Is it possible?I've been reading the Vue.js documentation but I didn't find anything about reading the data from DOM.If it is not possible,than how can I do that without Vue.js?Is there any other option? The main goal is to get this data and to put it into a js object passing it to another webpage.
you have to pass index key and use is to get from results 's position.
change the for loop div into
<div v-for="(result,i) in results" :key="i" class="col-sm-6" >
also chnange the methods parameter
<a href="/details" class="btn btn-info" @click="getData(i)" >Details</a>
and the method will get the index key and here i have used console to see the result.title that you have wanted. you can use it any how you want.
getData: function(key){
console.log(this.results[key].title)
}
so Given the next v-for:
<div class="container-fluid" id="networdapp" style="display:none;">
<div class="row" >
<div v-for="(result,i) in results" :key="i" class="col-sm-6" >
<div class="card m-3 h-240 bg-light" >
<div class="card-header text-center" > {{ result.title }} </div>
<div class="card-body" style="height:200px" >
<p class="card-text" v-html="result.prevDesc"></p>
</div>
<div class="card-footer bg-transparent border-info">
<a href="/details" class="btn btn-info" @click="getData(i)" >Details</a>
</div>
</div>
</div>
</div>
And the next Vue.js script:
<script type="text/javascript">
const vm = new Vue({
el: '#networdapp',
data: {
results:[]
},
methods: {
getData: function(key){
console.log(this.results[key].title)
}
},
mounted() {
axios.get('/getJson')
.then(response => {
this.results = response.data;
})
.catch( e => {
console.log(e);
});
}
});
To get the data you want to access in the results array, you can use an index in your v-for loop
v-for="(result, index) in results"
you can check the docs here https://v2.vuejs.org/v2/guide/list.html
I also strongly recommend you to add a key attribute after the v-for to help vue.js keep track of each result, see https://v2.vuejs.org/v2/guide/list.html#key
