I looked all over for a code that will that would highlight a piece of text when I hover (or click) another text.
For instance if I have the text 'Je suis ici. I am here', when i hover the word 'here' I will have a yellow bachground for the word 'here' and for the word 'ici'. So I can show that the word here is the english corespondent for the french word 'ici'.
Something like google translator uses: http://translate.google.com/
Thanks in advance for any suggestions!

The way that Google Translate does it, is to split up each word in a sentence into separate <span> tags with matching classes. These are then accessible via the DOM in JavaScript - most easily by using a framework such as JQuery.
For example, you could attach a mouseover() function to highlight the currently hovered word.
I can't give you a full example here - you'll need to come up with a starting point and develop your solution from there.
This uses the jquery library and is borrowed heavily from this answer on SO to a related question.
What it does is break up each word in a paragraph tag (<p>) and wrap it with a <span> tag with a class of highlightable and then attach an event on hover to the <span class='highlightable'> tags. If you want only one paragraph to be used, then give it an ID and bind only to those items in that given ID. If a few paragraphs, use a class or multiple IDs.
<p>Each word will be wrapped in a span.</p>
<p>A second paragraph here.</p>
<script type="text/javascript">
$(document).ready(function() {
// wrap words in spans
$("p").each(function() {
$(this).text().
replace(/\b(\w+)\b/g, "<span class='highlightable'>$1</span>");
});
// bind to each highlightable span
$('.highlightable').hover(
function() { $(this).css('background-color','#ffff66'); },
function() { $(this).css('background-color',''); }
);
});
</script>

I wrote a container-bound script and now want to make a report from it, by inserting the code into a Google Docs file. The problem is that with copy & paste from the Script Editor, the code is no longer colored or indented. I will need your help because I don't know how to make it well done.
I have this code :
createAndSendDocument() {
// Create a new Google Doc named 'Hello, world!'
var doc = DocumentApp.create('Hello, world!');
// Access the body of the document, then add a paragraph.
doc.getBody().appendParagraph('This document was created by Google Apps Script.');
// Get the URL of the document.
var url = doc.getUrl(); // Get the email address of the active user - that's you.
var email = Session.getActiveUser().getEmail();
}
As tehhowch said you'll need to write your own javascript code to do syntax formatting and then use the output of that.
You can use this https://www.w3schools.com/howto/tryit.asp?filename=tryhow_syntax_highlight they already have the script in place you only need to encode your html and put inside div id="myDiv" and run the javascript code.
<div id="myDiv">
Your encoded html goes here
</div>
Example
<div id="myDiv">
<!DOCTYPE html><br>
<html><br>
<body><br>
<br>
<h1>Testing an HTML Syntax Highlighter</h2><br>
<p>Hello world!</p><br>
<a href="https://www.w3schools.com">Back to School</a><br>
<br>
</body><br>
</html>
</div>
Make sure you first encode your html. [< -> <, > -> >, etc]
Then you can use the output of that . Sample : https://docs.google.com/document/d/1h8oDOZ0ReTgwxnYt2JKflHWJdlianSWWuBgbWcSdJC0/edit?usp=sharing

I'm trying to make a blog using Vue as laid out in the excellent demo here. I'd like to include some mathematical formulas and equations in my blog, so I thought I'd try to use vue-katex. vue-katex formats my mathematical notation perfectly when I put all my KaTeX HTML directly into my Vue templates, but to create a useable blog I need to keep my content separate from my templates (as shown in the demo).
I can't get vue-katex to format HTML content in the static folder. That's what I'd like help with.
Setup
I cloned the github repo for the demo.
I added vue-katex to package.json:
"vue-katex": "^0.1.2",
I added the KaTeX CSS to index.html:
<!-- KaTeX styles -->
<link
rel="stylesheet"
href="https://cdnjs.cloudflare.com/ajax/libs/KaTeX/0.9.0-alpha2/katex.min.css"
integrity="sha384-exe4Ak6B0EoJI0ogGxjJ8rn+RN3ftPnEQrGwX59KTCl5ybGzvHGKjhPKk/KC3abb"
crossorigin="anonymous"
>
I added the import statement to src/App.vue:
import Vue from 'vue'
import VueKatex from 'vue-katex'
Vue.use(VueKatex)
and I added a simple line of HTML with KaTeX to the BlogPost template:
<p>Here's an equation in the actual Vue template: <div class="equation" v-katex="'X \\sim N(\\mu, \\sigma^2)'"></div></p>
As I said, this works - I see formatted mathematical notation in my blog post (URL http://localhost:8080/read/neque-libero-convallis-eget):
However, I need different equations for every blog post, of course.
So I tried adding KaTeX HTML to the "content" field in the JSON for the first blog post: static/api/post/neque-libero-convallis-eget.json. I changed the "content" line to:
"content": "Here's an equation in the static folder: <div class=\"equation\" v-katex=\"'X \\sim N(\\mu, \\sigma^2)'\"></div>",
This content appears on the page, but the equation doesn't render. I see this: (the text appears but no equation is shown)
When I use Developer Tools to inspect the HTML on the page, I see this:
You can see that vue-katex has been applied to the equation I put in the template directly: it has parsed the HTML I typed into lots of spans with all the mathematical symbols, which are showing perfectly.
However the KaTeX HTML I've added to the "content" in the static folder has simply been placed on the page exactly as I typed it, and is therefore not showing up as an equation on the page. I really need to keep my blog post content in this static folder - I don't want to have to create a different .vue file for each blog post, that defeats the point!
My question is: is there a way to manually "apply" vue-katex to the HTML I place in the static folder, when it loads? Perhaps there is something I can add to the plugins/resource/index.js file, since this contains the function that loads the data from the static folder?
Many thanks in advance for any help.
*Disclaimer: I'm definitely no expert / authority on what I'm about to explain!
One thing to remember is that Vue reads the templates you write, and then replaces them as reactive components. This means that although you often write Vue attributes like v-for, v-html or in this case v-katex these attributes are only useful up until the app or component is mounted.
With this in mind, if you have a Vue app that ajax loads some html, its not going to be able to rerender itself with those Vue bindings in place.
I have somewhat ignored your current set up and set about solving the issue in another way.
Step 1: Reformat your data from the server side
I've put the posts into an array, and each post contains the template (just a string of html) and the equations separately as an array. I've used [e1] in the post as a placeholder for where the katex will go.
var postsFromServer = [{
content : `<div>
<h2>Crazy equation</h2>
<p>Look here!</p>
[e1]
</div>`,
equations : [
{
key : 'e1',
value : "c = \\pm\\sqrt{a^2 + b^2}"
}
]
}];
Step 2: When the post is rendered, do some work on it
Rather than just use v-html="post.content", I've wrapped the html output in a method
<div id="app">
<div v-for="post in posts" v-html="parsePostContent(post)">
</div>
</div>
Step 3: Create a method that renders all the katex, and then replaces the placeholders in the post
methods : {
parsePostContent(post){
// Loop through every equation that we have in our post from the server
for(var e = 0; e < post.equations.length; e++){
// Get the raw katex text
var equation = post.equations[e].value;
// Get the placeholder i.e. e1
var position = post.equations[e].key;
// Replace [e1] in the post content with the rendered katex
post.content = post.content.replace("[" + position + "]", katex.renderToString(equation));
}
// Return
return post.content;
}
}
Here is the whole set up, which renders Katex:

I'm trying to configure a nice footer on a pdf document I'm generating using Flying Saucer.
But I'm having problems getting the page number and page count in a nice position.
Consider this bit of css:
div#page-footer {
position : running(footer);
// .. more styling .. //
}
div.page-number:before {
content: counter(page);
}
Using this bit of html will not give me a page number:
<div id="page-footer">
<div class="page-number"></div>
</div>
The only way I manage to get a page number if I move the class a level up.
<div id="page-footer" class="page-number">
</div>
But this does not allow me to add additional content in the footer or makes it really difficult to apply styling. I could add a separate footer just for the page number, but it would be quite hard to get the position just right.
Is there a way to get page number + page count in a footer that also contains other elements and styling?
Extra notes:
I simplified the footer a bit, in the original there is more in there, but even this simple example it is giving problems.
using span or div for the element does not make a difference.
You should use the id instead of the class to identify the div containing the page number.
This will work:
div#page-number:before {
content: counter(page);
}
<div id="page-footer">
<div id="page-number"></div>
</div>
I am rather new to sharepoint and have been lucky enough to find the answer to all my questions with research. I have no found the answer to this question yet.... How do I add a text field WITHIN a folder that is WITHIN a document library. Example: I want to put instructions for upload within a specific folder. I tried to to the 'edit page' --> add text, but the text shows up at the top of ALL folders within that library and I just want it in one. Thank you for your assistance!
Kind regards,
Lanie
You can manage visibility of your message using JavaScript as below.
Don't directly add your message in text field; instead click of the text field you have added, and click "Edit HTML Source" in ribbon bar as highlighted in below image.
Then paste below code in newly opened window:
(Don't forget to replace "Your Message" and "FolderNameInWhichMessageToBeShown" in below code)
<div id="MyCustomMessage">
Your Message
</div>
<script type="text/javascript">
if(decodeURIComponent(document.URL).indexOf('FolderNameInWhichMessageToBeShown') == -1)
{
document.getElementById('MyCustomMessage').style.display = 'none'
}
else
{
document.getElementById('MyCustomMessage').style.display = 'block'
}
</script>
Click "OK" and Save your page.
I have two Hyper Links on to a DOJO DIv
var create = dojo.create("div",{
id:"create_links",
className:"iconRow1",
innerHTML:"<a class='popupLink' href='javascript:openCreateDialog()'>Create </a> <span>|</span><a href='javascript:openUploadDialog()'>Batch </a>"
},dojo.query(".ui-jqgrid-titlebar")[0]);
On click of the Batch Hyperlink , i have a function
function openUploadDialog()
{
// Here i want to disable the Create Hyper Link tried this way
dojo.byId('create_links')[1].disabled=true; // Not working
}
See whether i can answer your question.
HTML Part:
<div id="create_links">
g
h
</div>
JS Part:
dojo.addOnLoad(function() {
var a = dojo.query("#create_links a")[1];
dojo.connect(a,'click',function(e){
console.log(e.preventDefault())
})
})
#Kiran, you are treating the return of dojo.byId('create_links') like an array when that statement will return to you a node on the dom.
Also, hyperlinks don't support a disabled attribute to prevent them from being actionable. You could probably create a click handler that returns false to accomplish this type of functionality, or like #rajkamal mentioned, calling e.preventDefault(). #rajkamal also provides a good solution to selection the link properly.
