My front-end skills are fairly limited. I have a trained language model which generates 'tweets'.
I have this javascript function which currently displays the tweets as a paragraph.
function addResponse(msg) {
document.getElementById("results").textContent = ""
var para = document.createElement("div");
var s = "<div class='center' id='gpt2'> <b> Here what our BOT has to say... </b> </br></br>"
i = 1
for (var key in msg){
var value = msg[key];
console.log(value);
s = s + i + ") " + " <b>" + value + "</b> </br></br>"
i = i + 1
}
para.innerHTML = s + "</div>";
document.getElementById('append').appendChild(para);
}
Instead of displaying in a paragraph, I want to display as a proper tweet.
Here is a tailwind CSS implementation to create the UI of the tweet: https://codepen.io/webcrunchblog/pen/xedQVv
Currently this displays a fixed string "Starhopper". What I want to do is, loop through my array object 'msg' and display all the tweets with the proper UI .
Currently the addResponse() is called as part of ajax callback for successful response. From there how can I include the tailwind CSS code so that I can display every array element in its own tweet UI?
Hope the question is clear.
EDIT: Created this codepen if anyone wants to try it out: https://codepen.io/nikhilno1/pen/RwPBWvb
In the output, there is a tweet and three sentences. I want 3 tweets to be created for each of the sentence.
I've updated a bit of your code here: https://codepen.io/rxna/pen/OJVwMOm
The idea is to:
Clone the tweet element, have added a custom class for that:
var articleNode = document.querySelector(".tweet-body");
var clone = articleNode.cloneNode(true);
Update the text within each element:
var title = clone.querySelector(".tweet-text");
title.innerText = value;
And lastly append within the DOM:
document.getElementById("append").appendChild(clone);
It's not perfect but hopefully you'd get the idea.
First and foremost, hello. I'm a college student and not a very experienced coder, so forgive me if I end up saying something really dumb.
Either way, I have a school project in which I have to create a functional website using Node.js, where people are able to log in and buy stuff.
Most of the stuff already works, but I am having trouble with a very specific thing which I simply cannot get to work, yet is essential to the project itself.
I import data from a mySql database into the website using AJAX, that data contains products that people can buy. Then, those products are appended to the HTML page itself, and dynamically create two buttons for each product that is appended, one which says "Buy Now" and the other which says "Learn More".
Now, those buttons are supposed to be somehow associated to the values of the database, but I have no idea how to do this.
$(document).ready(function () {
$(function () {
$.ajax({
type: 'POST',
url: 'http://localhost:3000/getPacotes',
success: function (data) {
console.log(data);
for (var i = 0; i < data.length; i++) {
var pacoteSet1 = "<div class='col-md-4 pacotes'>";
var pacoteSet2 = "<input id=btnPac"+
i + " type='button' name='comprar' value='Comprar Pacote'>";
var pacoteSet3 = "</div>";
var idPacote = data[i].idPacote;
var nomePacote = data[i].Nome_Pacote;
$("#pacotes").append(pacoteSet1 +
"<h1>" + nomePacote + "</h1>" +
"<h1>" + nomePacote + "</h1>" +
"<h3>" + precoPacote + "euros/mes </h3>" +
pacoteSet2 +
pacoteSet3);
}
}
});
});
});
My teacher told me to give an attr to the buttons I create, and that's what I was pretty much trying to do now, but I dont know how to do that, I mean, if the buttons were static it would be pretty easy, but since the buttons are not there when the document is created, I dont know if this will work
$("#btnPac" + i).attr({"id": idPacote,
"nome": nomePacote,
"preco": precoPacote,
});
Anyway, Hopefully, I didn't sound too dumb and thanks in advance
TL:DR how do I give an attribute to a dynamically created button
You just need to change your jquery function like below:
$(document).find("#btnPac" + i).attr({"id": idPacote,
"nome": nomePacote,
"preco": precoPacote
});
This should be your solution.
You can do that while creating the html for button element. By using string concatenation, which you are already using while setting the ID:
var pacoteSet2 = "<input id=btnPac"+ i + " nome='" + nomePacote + "' preco='" + precoPacote + "' type='button' name='comprar' value='Comprar Pacote'>";
Overloading the HTML with attributes is a bad idea in my opinion. You could create the Elements in JS, bind the data to it, and then append the button to the dom. Thats quite easy with jquery:
var button=$("<button>Show More</button>");//create
button.on("click",showMore.bind({name:"test"}));//add listener
$(document.body).append(button);//append
function showMore(){
alert(this.name);
}
You can create a new input tag and set these attributes then append to your div with this code:
$('<input/>', {
id: 'btnPac' + i,
nome: nomePacote ,
preco: precoPacote ,
type: 'button'
}).appendTo("#pacotes");
You can do the same for your others (h1, h3)
Any idea how I could grab the link title from the query parameter and have it display somewhere on my landing page? I'm thinking a heading where it says "Welcome {whatever the link title is} and changes depending on which link has been clicked.
<a ng-click="link.clicks=link.clicks+1" href="#/landing?=link={{link.linktitle}}"><span>{{ link.linktitle }}</span></a>
My link shows up like this in the browser:
http://localhost:3000/#/landing?=broncos
I just need the Broncos part or whatever the link title is.
It should look like this:
example
All of the heavy functionality is happening inside of a controller.js file but I need to show the "(link title) are awesome! part on an HTML page
You could try this:
var str = "http://localhost:3000/#/landing?=link%3Dbroncos";
var pagenum = str.match(/link(.*)/)[1];
alert(pagenum); // %3Dbroncos
https://jsfiddle.net/7nbLs5ww/
EDIT:
var str = "localhost:3000/#/landing?=broncos";
var pagenum = str.match(/landing\?\=(.*)/)[1];
alert(pagenum); // broncos
https://jsfiddle.net/7nbLs5ww/1/
EDIT 2:
var str = "http://www.your_url.com/landing/?link=wolverines";
var pagenum = str.match(/\?link\=(.*)/)[1];
document.getElementById("result").innerHTML = pagenum[0].toUpperCase() + pagenum.slice(1)+" are awesome!";

Our application is been internationalized and being changed to different languages. For that reason we have to hard code all the messages. How can we do that for messages in javascript ?
This is how we are doing in html messages.
<span th:text="#{listTable.deletedFromTable}">deleted</span>
How do we hard code for javascript messages.(update the table)
$('#TableUpdate-notification').html('<div class="alert"><p>Update the Table.</p></div>');
You will need to put the messages in the DOM from the start, but without displaying them. Put these texts in span tags each with a unique id and the th:text attribute -- you could add them at the end of your document:
<span id="alertUpdateTable" th:text="#{listTable.updateTable}"
style="display:none">Update the Table.</span>
This will ensure that your internationalisation module will do its magic also on this element, and the text will be translated, even though it is not displayed.
Then at the moment you want to use that alert, get that hidden text and inject it where you need it:
$('#TableUpdate-notification').html(
'<div class="alert"><p>' + $('#alertUpdateTable').html() + '</p></div>');
You asked for another variant of this, where you currently have:
$successSpan.html(tableItemCount + " item was deleted from the table.", 2000);
You would then add this content again as a non-displayed span with a placeholder for the count:
<span id="alertTableItemDeleted" th:text="#{listTable.itemDeleted}"
style="display:none">{1} item(s) were deleted from the table.</span>
You should make sure that your translations also use the placeholder.
Then use it as follows, replacing the placeholder at run-time:
$successSpan.html($('#alertTableItemDeleted').html().replace('{1}', tableItemCount));
You could make a function to deal with the replacement of such placeholders:
function getMsg(id) {
var txt = $('#' + id).html();
for (var i = 1; i < arguments.length; i++) {
txt = txt.replace('{' + i + '}', arguments[i]);
}
return txt;
}
And then the two examples would be written as follows:
$('#TableUpdate-notification').html(
'<div class="alert"><p>' + getMsg('alertUpdateTable') + '</p></div>');
$successSpan.html(getMsg('alertTableItemDeleted', tableItemCount));
I have a javascript that displays a generated text into a div:
document.getElementById('phrase').innerHTML = phrase;
PHRASE_TEXT_GETS_SHOWN_HERE
Basically I'm trying to set up a link that will take the text and post it to twitter with a link:
Clicky for tweety
How can I include the generated text in the link?
Do you mean like:
function setPhrase(phrase) {
var url = 'http://twitter.com/home?status=' + encode(phrase);
$('#phrase').html('' + phrase + '');
}
...?
Un-jQuerying it should be straightforward enough, if that's how you roll.
This is un-jQueried:
function setPhrase(phrase) {
var url = 'http://twitter.com/home?status=' + encodeURI(phrase);
document.getElementById('phrase').innerHTML = '' + phrase + '';
}
If you didn't see my failbraining encode for encodeURI as an error you should use Firebug. It may also fail if you have more than one element with the id phrase or if you have no elements with the id phrase.
