How to send data into span instead of input using this.$emit

With VueJS current I am calculating my data and passing it through my HTML and use it there but the only way for now I know is this for example:
this.$emit('input', this.finalPrice)
And in my HTML like this:
<input type="number" v-model="finalPrice" disabled />
Now I want to know if it is possible to send data into a <span> or <div> or anything instead of input I tried to change the <input> name to and use the v-model for span but no luck with it.

vue.js binding value from dynamically generated input

I have the below code for generating comments (cutted down for simplicity sake):
<div v-for="(g, gi) in submission.goals" :key="gi">
<div>
<p >Goal #{{gi+1}}</p>
<div>{{g.text}}</div>
</div>
<div>
<p>Comments:</p>
<div><span class="uk-text-small uk-text-muted"><i>no comments</i></span></div>
<hr>
<div>
<textarea class="comment-input" placeholder="type your comment here"></textarea>
</div>
</div>
</div>
and my method look like this:
submitComment(gid,uid,phase,e)
{
e.preventDefault();
//var comment -> get the value of the closes textaraea here
console.log(gid, uid, phase, comment);
//here I will make the ajax call to the API
}
As you can see the whole thing is generated in a v-for loop generating divs according to the size of the submission.goals array returned by the API.
My question is how can I get the value from the textarea input closest to the anchor that is calling the submit function.
Obviously I can't have a separate data object for each comment area since I do not have a control over the size of submission.goals array. And if I use v-model="comment" on each input, whatever user types in will be automatically propagated to each and every textarea.
I know how to handle this with jQuery, but with Vue.js I am still in the early learning stages.

If you mark the text area as a ref, you could have a list of textarea elements. With the index number of the v-for items (gi in your case), you can get the [gi] element of the refs list and submit its value.
<textarea ref="comment" class="comment-input" placeholder="type your comment here"></textarea>
submitComment(gid,uid,phase,e, gi)
{
e.preventDefault();
var comment = this.$refs.comment[gi].value;
console.log(gid, uid, phase, comment);
//here I will make the ajax call to the API
}

Try change submission.goals to computed submissionGoals and create this computed with the code above:
submissionGoals(){
return this.submission.goals.map(goal => ({...goal, comment: ''}));
}
Use v-model="g.comment" on textarea.
Now change submitComment(g.id, g.user_id, g.phase, $event) to submitComment(g, $event) like Alexander Yakushev sayed.

passing the values dynamically (eg: innerHTML) to another element as a value

I've a form with three fields, which are rendered via the jinja2 template & the fields are part of a Django ModelForm. The fields are: CharField, FileField, and Textarea.
And, I've also a textarea like <div> element which exactly works like Stackoverflow's editor, omitting some options like <code>, <image> ...
But, it's totally JavaScript based. Which when rendered on the page disabling that existing TextArea that was rendered from the ModelForm. As, I defined on the page...
<script>
$(document).ready(function () {
$('#txtArea').TxtEdtr();
});
</script>
I've mentioned both the element's IDs same, to always render the second textarea by overriding the first one. And, by hiding that element by - display: none.
And to pass the context of the 2nd created textarea to that modelform textarea, I've used:
$('.myeditor').keyup(function () {
$('#txtArea').innerHTML = $('.myeditor').html();
});
By looking at the browser console I can see that keyup is working but, the context or the 1st element isn't affected. And, as it's a required element I can't submit the form also.
For example, I want to pass that html context as a string to that ModelForm's textarea element before the form is submitted:
$('#txtEditor').innerHTML = $('.editor').html();
result to pass: "<span style=\"font-style: italic;\">hi there ...<br></span>"
which is shown to the console while I ran that code, but not able to pass.
The DOM structure:
<div class="form-group">
<!-- model form element -->
<label for="txtEditor">Body of article</label>
<textarea name="details" cols="40" rows="10"
id="txtEditor" class="form-control" required="" style="display: none;">
</textarea>
<!-- after rendering -->
<div class="row-fluid main ted">
<div id="menubar_txtEditor" class="row-fluid menu-bar">
<!-- menubuttons are displayed here -->
...
...
</div>
<div class="editor" name="details" style="overflow: auto;" contenteditable="true">
<!-- portions here dynamically added if textarea has
any content inside -->
<span style="font-style: italic;">hi there ...<br></span>
</div>
</div>

You can do something like this:
// add data to the editor
$('.editor').prepend($('#txtEditor').val());
// initialize TxtEdtr
window.quill = new Quill('.editor', {
theme: 'snow'
});
// Update the model textarea value after submit
$('form').on('submit', function() {
$('#txtEditor').val(quill.root.innerHTML);
});
Vist jsfiddle, for more.
check network on jsfiddle, it's submitting the desired data.

How to bind a $scope variable with text editor in angularjs

This is my Editor input tag:
<textarea cols="18" rows="40" class="wysihtml5 wysihtml5-min form-control" ng-model="TemplateDescription"></textarea>
When binding my $scope variable with ng-model then it returns undefined. and when I bind my $scope variable with ng-bind-html then still the same result. So then I gave an Id to this textarea and accessed the value inside of it by using this statement.
$scope.TemplateDescription = $sce.trustAsHtml($("#templateDescription").val());
I get the values as shown in the image below, so how can I get my required html text in my modal so that I can pass this value to save into database. Any kind of help will be appreciated.

If your TemplateDescription variable is containing raw HTML then you can try something like this.
First you need to set your raw HTML as trusted.
$scope.TemplateDescription = $sce.trustAsHtml($scope.TemplateDescription);
And then you need to bind TemplateDescription using ng-model
<textarea cols="18" rows="40" class="wysihtml5 wysihtml5-min form-control" ng-model="TemplateDescription"></textarea>
I have tested it. It will work.

Populate form field with javascript

I have a form with several fields populated by the user and before it is submitted some javascript gets called when a check button. It tries to set the value of the form fields to a variable that exists in the js function.
document.getElementById('var1').innerHTML = test;
alert(test);
I know the javascript is working as expected because I see the alert but the form boxes are not getting populated:
#helper.input(testForm("var1")) { (id,name,value,args) => <input type="text" name="#name" id="#id" #toHtmlArgs(args)> }

innerHTML is used to get/set the body of an html tag, so you're probably ending up with this in the html:
<input ...>test</input>
I think this may work for a <textarea>, but for your <input type="text"> you want to set the value attribute.
document.getElementById('var1').value = test;

If you want to programmatically set an html form field via JS there are many ways to do this and many libraries out there that make it really easy.
Such as various JS two-way component template binding libraries.
For instance, you can simply do the following:
HTML:
<div id="myapp">
<input id="var1"/>
<button>Submit</button>
</div>
JS:
mag.module('myapp',{
view : function(state){
var test= 'tester';
state.button= {
_onclick:function(){
state.var1=test
}
}
}
});
Here is working example of the above example:

Hope that helps!
