How to combine html, javascript and css files into one .Vue component, grid component with external data

I saw this example on Vue.js website. This is an example of creating a reusable grid component and using it with external data.(If you want to see how it functions, here is the link : https://v2.vuejs.org/v2/examples/grid-component.html?) I have a basic understanding of how single file component works. I know <template> <script> <style> are accordingly for html, javascript and css parts. But I don't know how to make this grid component with external data fit in the skeleton. I didn't find any online tutorials about this. Please show how to fit this three files into one .vue file. Thank you.
HTML:
<!-- component template -->
<script type="text/x-template" id="grid-template">
<table>
<thead>
<tr>
<th v-for="key in columns"
#click="sortBy(key)"
:class="{ active: sortKey == key }">
{{ key | capitalize }}
<span class="arrow" :class="sortOrders[key] > 0 ? 'asc' : 'dsc'">
</span>
</th>
</tr>
</thead>
<tbody>
<tr v-for="entry in filteredHeroes">
<td v-for="key in columns">
{{entry[key]}}
</td>
</tr>
</tbody>
</table>

I don't know what to do with the javascript file in <script>, obviously I can't just copy it and paste. But I am confused about what changes I should make.

Assuming you've set up your build pipeline properly your SFC doesn't look correct. Taking a deeper look into the guide about SFC you have to wrap each part of your code into its own block, meaning.
HTML (template)
JavaSCript (script)
CSS (style)
Your SFC would then have to look like this.
<template>
<!-- HTML markup here -->
</template>
<script>
// JavaScript code here
</script>
<style>
/* CSS stylings here */
</style>
In your very example, you're mixing the template and script block which is not supposed to look like that.

How to pass a parentNode.id as a parameter to an element out of the querySelector

I have these elements created inside a "querySelector('ul'). It's working property.
I want the "blue-Save" button to have the same function as the "yellow-Save".
But the Blue-save button was created in the HTML file, and the Yellow-Save button was created in JavaScript to listen to an event from the "querySelector('ul').
Is there anyway I can just link the Blue-Save to react as if I was clicking in the Yellow-Save?
(I'm sorry if I didn't explain it property or If it seems too confused, this is my first application, It doesn't seems too organized but I'm focused in making things work before dive in 'well developed apps').
Thank You Everyone!

You can add a common class to both blue and yellow buttons, and attach a click event by the class name like below
$(".custom_save_button").on("click", function() {
//your code
});

Since you are creating that button, sharing the same class won't just work as expected, instead use delegated events which allow you to attach events on new elements added to the DOM
Add a common class for both and then add an event listener for that class using event delegation.
For this example Let's suppose you chose the class name: stack_class
//I added this function for you to be able to know if an element has a class
function hasClass( target, className ) {
return new RegExp('(\\s|^)' + className + '(\\s|$)').test(target.className);
}
//you could change body to the closest parent's selector both buttons share
document.querySelector('body').addEventListener('click', function(event) {
var clickedElement = event.target;
if(hasClass(clickedElement, "stack_class")) {
//create your functionality for both buttons here
}
});

If you assign a common class to both buttons, then you can add the same event listener to all buttons that have that class. Here is a simple example:
var saveButton = document.createElement('button');
saveButton.textContent = 'Save';
saveButton.className = 'save-button yellow-button';
body = document.querySelector('body');
body.appendChild(saveButton);
buttons = document.getElementsByClassName('save-button');
for (var i = 0; i < buttons.length; i += 1) {
buttons[i].addEventListener('click', function (event) {
alert('Hello!');
});
}
.yellow-button {
background: #ffff00;
}
.blue-button {
background: #0000ff;
}
<button class="save-button blue-button">Save</button>

"float: left" div gets pushed down on input focus

I have the following form for lyrics upload. I've changed the design of the form a little bit, and now facing a weird problem.
I've created a fake-datalist using JS. On input focus, a fake-datalist (an ul element) is appended next to the input element. Its position is set to absolute so it shouldn't disrupt the flow of the document when it appears. However, it does. I can't seem to identify the problem. Once the datalist appears, the div next to the table gets pushed down. Table width isn't changing when the datalist appears, so it's not squizing the div and pushing it down.

Removing overflow: auto; from #songInput, the parent element of the table and the div, solved the problem. Although, I don't understand why overflow: auto; on the parent would push the div down. Dynamically added ul.datalist's position is set to absolute, and when it appears, the only thing it might do is extend the height of the table, which shouldn't effect the div at the right.

Improve this question
can anyone help me with my js selector functions? The problem is the color and size indicator numbers showing do not default back to "blank" after mouseout. I want the indicator number to disappear after mouseout if a mouseclick never happens over the function. Can anyone help? My demo http://jsfiddle.net/jwjxr2oh/3/
Thanks

The problem is when sizeIndicator.data('selected') is not present sizeIndicator.data('selected') will return undefined, then the text() method will act like a getter method and will not update the value to blank so
$(function() {
var colorsList = $('#colors');
var sizesList = $('#sizes');
var colorIndicator = $('#color_indicator');
var sizeIndicator = $('#size_indicator');
var colors = [{
id: 1,
name: 'Dark Blue Denim',
color: '#0B3861'
}, {
id: 2,
name: 'Light Blue Denim',
color: '#81BEF7'
}];
var sizes = [{
id: 1,
name: '26'
}, {
id: 2,
name: '28'
}, {
id: 2,
name: '30'
}, {
id: 3,
name: '32'
}];
$.each(colors, function() {
colorsList.append(
$('<li>').attr({
id: 'color_' + this.id
})
.data('info', this)
.append(
$('<div>').css('background-color', this.color)));
});
$.each(sizes, function() {
sizesList.append(
$('<li>').attr({
id: 'size_' + this.id
})
.data('info', this)
.text(this.name)
.addClass('text'));
});
colorsList.selectable({
selected: function(event, ui) {
var total = $(ui.selected).siblings('li.ui-selected').length + 1;
if (total > 1) {
$(ui.selected).removeClass('ui-selected');
} else {
var color = $(ui.selected).data('info').name;
colorIndicator.data('selected', color).text(color);
}
}
});
sizesList.selectable({
selected: function(event, ui) {
var total = $(ui.selected).siblings('li.ui-selected').length + 1;
if (total > 1) {
$(ui.selected).removeClass('ui-selected');
} else {
var size = $(ui.selected).data('info').name;
sizeIndicator.data('selected', size).text(size);
}
}
});
sizesList.children('li').hover(function() {
sizeIndicator.text($(this).data('info').name);
}, function() {
console.log(sizeIndicator)
sizeIndicator.text(sizeIndicator.data('selected') || '');
});
colorsList.children('li').hover(function() {
colorIndicator.text($(this).data('info').name);
}, function() {
colorIndicator.text(colorIndicator.data('selected') || '');
});
$('#show').click(function() {
var color = colorsList.find('li.ui-selected').eq(0).data('info');
var size = sizesList.find('li.ui-selected').eq(0).data('info');
if (typeof color != 'undefined') {
alert('Color selected: ' + color.name + ', id: ' + color.id);
}
if (typeof size != 'undefined') {
alert('Size selected: ' + size.name + ', id: ' + size.id);
}
});

Typeahead.js - Unable to choose suggestion

I must be an idiot. I am using the Typeahead.js plugin. I am trying to use custom templates for suggestions. While my custom templates appear, I cannot use the arrow-keys to actually select an item. If I hover over an item, the selection doesn't get highlighted either. I thought it might be just a styling issue. However, if 3 suggestions appear, and I click the down arrow twice, then enter, my selected option does not appear in the text box. Alternatively, if I choose an option with my mouse, the option does not appear in the box.
What am I doing wrong? Currently, I have the following:
var suggestions = new Bloodhound({
datumTokenizer: Bloodhound.tokenizers.obj.whitespace('value'),
queryTokenizer: Bloodhound.tokenizers.whitespace,
remote: {
url: '/api/suggests?querytext=%QUERY',
filter: function(results) {
return $.map(results.Results, function(suggestion) {
return suggestion;
});
}
});
suggestions.initialize();
$(document).ready(function() {
$('input.typeahead').typeahead(
{ minLength: 3 },
{
name: 'suggestions',
source: suggestions.ttAdapter(),
templates: {
suggestion: function(data) {
var str = '';
if (data.Type === 'Customer') {
str += '<i class="icon-1"></i>';
} else if (data.Type === 'Product') {
str += '<i class="icon-2"></i>';
}
str += '<div>' + data.Name + '</div>';
return str;
}
}
}
);
});
The suggestions popup. The results come from the following JSON:
{
"Results":[
{
"Type":"Customer",
"Id":5,
"Name":"Bill",
"LastUpdated":"01-01-2015"
},
{
"Type":"Customer",
"Id":135,
"Name":"Billows",
"LastUpdated":"01-02-2015",
},
{
"Type":"Product",
"Id":241,
"Name":"Bill Check",
"LastUpdate":"01-04-2015"
}
],
"TotalResults":3,
"TotalCustomers":2,
"TotalProducts":1
}
How do I a) Apply a highlight to an item when a use hovers over an item with the mouse or uses the arrow keys to get to it b) Put the select item's Name value in the input box when the suggestion is selected?
Thanks!

Try
$(function () {

filter: function(results) {
return $.map(results.Results, function(suggestion) {
return {value:suggestion.Name, suggest:suggestion};
});
}
});
suggestions.initialize();

str += '<i class="icon-1">' + data.suggest.Type + '</i>';
} else if (data.suggest.Type === 'Product') {
str += '<i class="icon-2">' + data.suggest.Type + '</i>';
}
str += '<div>' + data.value + '</div>';
return str;
}
},

});
})
$(function () {

Have you tried adding a valueKey to your function pointing it to name? See SO answer here:
Typeahead.js does give me suggestions but doesn't select them
