I am attempting to build a search engine with an Elasticsearch backend and a Vue.js front end. It is primarily based upon this tutorial. It was suggested that a nice feature would be to highlight search results with the initial search term ie if I search "foo" in the search bar, then a search result would look something like foobar.
I have tried placing the v-html block into various divs, but usually to no success.
My elastic index records that match this format:
result._source.Title,
result._source.description,
result._source.contact,
result._source.contactEmail
HTML:
<div class="row">
<div class="col-md-6" v-for="result in results" v-html="highlight(result._source.Title)">
<div class="ul">
<ul>
<li>{{ result._source.Title }},</li>
<li>{{ result._source.description }},</li>
<li>{{ result._source.contact }},</li>
<li>{{ result._source.contactEmail }} </li>
JS: highlight function
highlight(text) {
return text.replace(new RegExp(this.query, 'gi'), '<span class="highlight">$&</span>')
}
}
I have been able to implement basic functionality to highlight a single data point, but the rest of the page does not render. For instance, in this example, title will be highlighted, but the description, contact, and contactEmail will not render on the page. Additionally, if the search term does not match the title, the page errors out.
It's likely due to to the function call in your v-html directive: highlight(result._source.Title).
Instead you should be using v-html to bind to each result property, which allows you to replace occurrences in any of the properties before updating the template.
Try updating your code similar to the following:
new Vue({
el: '#app',
data() {
return {
content: [{

Now, my query is; how to I convert <img> into <amp-img>?
There is no way to convert. You have to replace the img elements with amp-img elements.
And you have to use amp-img attributes src and layout, width and height with respect to layout.
I should build this layout
layout
but after various tests, I don't understand how place the image.
The text continues from one div to another. I've think to use the column CSS3 property but I think it's not the better solution.
How can I implement this layout?
Thanks in advice.
EDIT:
This is the HTML and CSS code of the last test:

This is Jsfiddle of the last test:
http://jsfiddle.net/DVwws/
After working with the example you found here I was able to edit the source code and eventually create a JSFiddle with your desired result.
General guide to accomplish this:
Create two side-by-side divs filled with text
Use the "Content" CSS property to create "holes" in your paragraphs where they are desired with content: ""; width: 125px; height: 250px;.
Use absolute positioning to place an image within that "hole" you created.
This image should assist in understanding the placing concept: (Just imagine the green-section as being the hole and centered vertically)
Here is the HTML and CSS from the JSFiddle I made:
<style>
#page-wrap { width: 100%; margin: 80px auto; position: relative; }
#logo { position: absolute; top: 125px; left: 50%; margin-left: -125px; }
.left, .right { width: 49%; text-align: justify}
.left { float:left; }
.right { float:right; }
#l, #r { width: 100%; position: relative;}
#l { float: left; text-align: justify}
#r { float: right; text-align: justify}
#l:before, #r:before { content: ""; width: 150px; height: 250px; vertical-align:-50%;}
#l:before { float: right;}
#r:before { float: left; }
</style>

Also since you said you were loading your text dynamically from a data-base here is an easy way to calculate it's length and break it into two equal chunks.
<?php
//some SQL Queries setting $str
$len = strlen($str);
$part1 = substr($str, $len/2);
$part2 = substr($str, $len/2+1,$len);
// Insert $part1 & $part2 text chunks into each div.
?>
NOTE: Due to the exact cut, if that character number is in the middle of a word that word will be cut into two parts. There are resources to easily figure out how to cut on the next space; but that does not pertain to this specific question.

i tried with
//img[1]/#width
but not working. Basically i need a XPATH for to get height or width of an img tag irrespective of case(WIDTH or width) and if the width attribute is not available it should return no match or null
Use:
(//img)[$k]/#*[name() = 'width' or name() = 'WIDTH']
Where you need to replace $k ith the desired image index.
This selects the attribute named "width" or named "WIDTH" of the $k-th img element in the XML document.
For example, for the 3rd image use:
(//img)[3]/#*[name() = 'width' or name() = 'WIDTH']

I'm trying to create a yahoo pipe that will change the tag names, in which I'm using the rename module, and it works fine.
Now, I'm wanting to get rid of the description tag, so my XML only returns name and age.
How can I do that with yahoo pipes?
Cheers in advance for any help
Use the Regex module on the description field and replace .* with an empty textfield. That deletes the field.
Use the "Create RSS" module as the last step in the chain. Then only include the fields you want.
