I don't know how to search this problem in Stackoverflow it gives different solutions and does not relate to my problem. So I'll be needing your help again guys.
Values of variable obj:
item.title = Title1 and Title2
item.description = Description1 and Description2
HTML FILE:
function test_pop() {
var fb_id = "xxxxxxxxxxxx";
var v_id = "xxxxxxxx";
$.post('http://mysite.com/myfile.php', {fb_id: fb_id, v_id: v_id}, function(data) {
var obj = $.parseJSON(data);
$.each(obj,function(index, item){
achievement = "You Obtained " + item.title + " " + item.description;
achievement_pop(achievement);
});
});
}
achievement_pop function:
function achievement_pop(data) {
$("#achievement_popup").html(data).show(); //DIV that should show up
}
So the problem is, when the div shows up, it only outputs:
<div> <!-- Imagine that this content is inside a DIV -->
**You Obtained Title2 Description2**
</div>
But my desire output is:
<div> <!-- Imagine that this content is inside a DIV -->
**You Obtained Title1 Description1**
**You Obtained Title2 Description2**
</div>
Hope you guys help me, thanks.
the html function is replacing the whole content of the div, it's not just adding.
A solution would be to replace
$("#achievement_popup").html(data).show();
with
$("#achievement_popup").html($("#achievement_popup").html()+data).show();
But it's a little heavy. Personally I would first build the html and use the html function only once.
Use append() to add to end of element and not replace the content completely with html()
Or if you want to replace the existing content with all the new content at once:
/* start with empty string*/
var achievement='';
$.each(obj,function(index, item){
/* add to string on each pass of loop - can use any html you want here*/
achievement += "You Obtained " + item.title + " " + item.description +'<br>';
});
/* update element once all data parsed*/
achievement_pop(achievement);
Parsing to string and making one update is the most efficient from processing standpoint

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.
I have some code that is roughly along the lines of this:
exportValue = [];
function reduceArray() {
//does something
exportValue = parseFloat(exportValue)
}
From that, I get that exportValue is 73951. I then have to add that number to the page... so I tried both of these:
$("#exportValueDiv").append(exportValue);
$("#exportValueDiv").append("<li>" + exportValue + "</li>");
But that doesn't work.. I'm confused on how to add something like a variable to the DOM....
If I do something like:
$( "#exportValueDiv" ).append( "<li>value</li>")
it works, but I don't want to add a string, I want to add the value of the variable. I looked this up, but I'm still confused, so any help would be greatly appreciated!!!
Look into jQuery manipulation
$("#exportValueDiv").text(exportValue); //Replaces text of #exportValueDiv
$("#exportValueDiv").html('<span>'+exportValue+'</span>'); //Replaces inner html of #exportValueDiv
$("#exportValueDiv").append('<span>'+exportValue+'</span>'); //Adds to the inner html of #exportValueDiv
The .append() contract expects a DOM element or HTML String. You will need to do:
$("#exportValueDiv").append("<div>" + exportValue + "</div>");
Try this:
$("#exportValueDiv").append("<div>" + exportValue + "</div>");
The following appends your variable to a div that already has information:
<div id="exportValueDiv">
<p>
Some information.
</p>
</div>
<script>
var exportValue = "Hello world.";
$("#exportValueDiv").append('<p>'+ exportValue +'</p>');
</script>

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));
QUESTION ::
I know this is a redundant question, but I am finding little help in other similar questions...
I have a json file.
I can load the json fine, but when I try to output a specific element with this
div.innerHTML = jsonfromfile[element];
I only get this...
[object Object]
as my output...
How do I get the entire element to display instead of this [object Object]?
more code to get a feel for how it is being done up...
var activity;
function jsfr() {
$.getJSON('myjson.json', function(response){
jsonfromfile = response;
})
}
.

SOLUTION :: from Francis Stalin's answer
I added a new function...
var items;
function outty(data) {
$.each(data, function(key, val) {
items=items+key+","+val+";";
});
}
and i set the depth on the json leaving me with an object which i send to outty...
dpth = jsonfromfile["elementOne"]["elSubone"]["elsuboneSub"];
outty(dpth);
div.innerHTML=items;
here's the HTML that shows the div it all prints to...
<div class="col-rght">
<div class="text" id="postcomp"></div>
</div> <!--div class="col-rght"-->
this turns the object of your desired json depth into an ugly string that you can then format for display..
if you like html lists check out how Stalin did it, but be weary of his appendTo('div')... this will place your list in every div. Try putting the name of the class of the div you want to print to with a period leading it, appendTo('.outputbox')
you can't append the json object directly into ur html. u have to parse and convert into string
$.getJSON('myjson.json', function(data) {
var items = [];
$.each(data, function(key, val) {
items.push('<li id="' + key + '">' + val + '</li>');
});
$('<ul/>', {
'class': 'my-new-list',
html: items.join('')
}).appendTo('div');
});
http://api.jquery.com/jQuery.getJSON/
Use JSON.stringify(yourjsonobjecthere)
Try div.innerHTML = JSON.stringify(jsonfromfile[element]);
My code works fine in other browsers, but in IE8 I get "error on page" - and when I click that it says:
"Exception thrown and not caught Line: 16 Char: 15120 Code: 0
URI: http://ajax.googleapis.com/ajax/libs/jquery/1.6.1/jquery.min.js"
I tried linking to jquery.js (rather than jquery.min.js) and to 1.5.1/jquery.min.js,
but problem still remains.
Can someone correct/improve my code for me, or guide me as to where to look. Thanks
<script type="text/javascript">
function fbFetch()
{
var token = "<<tag_removed>>&expires_in=0";
//Set Url of JSON data from the facebook graph api. make sure callback is set with a '?' to overcome the cross domain problems with JSON
var url = "https://graph.facebook.com/<<ID_REMOVED>>?&callback=?&access_token=" + token;
//Use jQuery getJSON method to fetch the data from the url and then create our unordered list with the relevant data.
$.getJSON(url, function(json)
{
json.data = json.data.reverse(); // need to reverse it as FB outputs it as earliest last!
var html = "<div class='facebook'>";
//loop through and within data array's retrieve the message variable.
$.each(json.data, function(i, fb)
{
html += "<div class='n' >" + fb.name;
html += "<div class='t'>" + (dateFormat(fb.start_time, "ddd, mmm dS, yyyy")) + " at " + (dateFormat(fb.start_time, "h:MMtt")) + "</div >";
html += "<div class='l'>" + fb.location + "</div >";
html += '<div class="i"><a target="_blank" title="opens in NEW window" href="https://www.facebook.com/pages/<<id_removed>>#!/event.php?eid=' + fb.id + '" >more info...</a></div>';
html += "</div >";
}
);
html += "</div>";
//A little animation once fetched
$('.facebookfeed').animate({opacity: 0}, 500, function(){
$('.facebookfeed').html(html);
});
$('.facebookfeed').animate({opacity: 1}, 500);
});
};
Does the code do the job in IE8 or does it break? The reason I ask is because if it works as expected you could just wrap it in a try{ } catch{ \\do nothing } block and put it down to another thing IE is rubbish at.
You may be better off creating an object for the creation of the facebook div. Something like...
var html = $('<div />');
html.attr('class', 'facebook');
Then in your each loop you can do this...
$('<div />').attr('class', 'n').append(fb.name).appendTo(html);
$('<div />').attr('class', 't').append etc...
Then append html to the facebookfeed object
Doing this may remove the scope for error when using single quotes and double quotes when joining strings together, which in turn may solve your issue in IE8
$('.facebookfeed').fadeOut(500, function(){
$(this).append(html).fadeIn(500);
});
Hope this helps!
UPDATE
The append method is used to add stuff to a jquery object. For more info see here
So to surround the div's as you mentioned in the comments you would do something like this...
var nDiv = $('<div />').attr('class', 'n').append(fb.name);
$('<div />').attr('class', 't').append(fb.somethingElse).appendTo(nDiv);
// etc
And then you would need to append that to the html div like so...
html.append(nDiv);
So that would give you
<div class="facebook">
<div class="n">
value of fb.name
<div class="t">
value of fb.somethingElse
</div>
</div>
</div>
So what you have done is created a new jquery object and appended to that, then appended that to the html object which you have then appended to the facebookfeed div. Confusing huh?!
