How to write all data from Array? - javascript

I have HTML like :
<div id="divid">
1
2
3
.....................
</div>
I have script to get all links from a div like :
<script>
var links = document.getElementById('divid').getElementsByTagName('a') ;
</script>
Then I want write link into class like :
<script>
var links = document.getElementById('divid').getElementsByTagName('a') ;
document.write("<div class="'+link[1]+" "+ link[i]+'">Class is added links</div>");
</script>
That mean after write I have HTML:
<div class="d#link1 d#link2 d#link3">Classes is added links</div>
How can I do this? Using for loop or not? how?

You have to get the href property from each element. Put them in an array, and you can just join the strings:
var elements = document.getElementById('divid').getElementsByTagName('a');
var links = [];
for (var i = 0; i < elements.length; i++) {
links.push(elements[i].href);
}
document.write("<div class="' + links.join(" ") + '">Class is added links</div>");

Use join in combination with map:
var classString = links.map(function(link) { return link.attributes.href; } ).join(' ');

JS exstract part of URL from multiple form fields

I have a form that has multiple fields all with the same class. These are populated with URL's that follow the same structure. I am trying to extract the same section from each URL. So far var res = x.split('/')[5]; will achieve this but only for the first URL. I can also use var x = document.querySelectorAll(".example") to change all the url's but I cannot find the correct way to combine both of these function. so far my code looks like this:
script>
function myFunction() {
var x = document.querySelectorAll(".example").innerHTML;
var res = x.split('/')[5];
var i;
for (i = 0; i < x.length; i++) {
x[i].innerHTML = res;
}
}
</script>
I have looked around but can't find a solution that fits. Thanks in advance for your help.
So loop over the HTML Collection, this is making assumptions based on code.
// Find all the elements
var elems = document.querySelectorAll(".example")
// loop over the collection
elems.forEach(function (elem) {
// reference the text of the element and split it
var txt = elem.innerHTML.split("/")[5]
// replace the text
elem.innerHTML = txt
})
<div class="example">1/2/3/4/5/a</div>
<div class="example">1/2/3/4/5/b</div>
<div class="example">1/2/3/4/5/c</div>
<div class="example">1/2/3/4/5/d</div>
<div class="example">1/2/3/4/5/e</div>
<div class="example">1/2/3/4/5/f</div>

find values of custom attribute in html using Jquery

Click here for code
Inside loop of {listOfValue}
i want to find different column values filtered by data-week = {listofvalueObject}
and want to add data in each row based on column segregated by this data-week attributes value.
I have assigned the values form a list so it every column has different data-week value.
I have tried :
var allColumnValClass = j$('.columnVal').filter('[data-week]');
var allColumnValClass = j$('.columnVal').filter('[data-week='Something dynamic ']');
You should be able to select them like this:
var allColumnValClass = j$('.columnVal[data-week]')
and
var allColumnValClass = j$('.columnVal[data-week="' + Something dynamic + '"]')
Hope this helps.
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class='columnVal' data-week="1"></div>
<div class='columnVal' data-week="2"></div>
<div class='columnVal' data-week="3"></div>
<script>
var dataList = $(".columnVal").map(function () {
return $(this).data("week");
}).get();
for (var i = 0; i < dataList.length; i++) {
console.log(dataList[i]);
}
</script>

Get the id numbers (separatly) from the url and use it to select the id with that ID number (using jquery)

I am working on a website where I dont have any control on the code (functionality side. however even if I had the access I wouldn't be able to make any changes as I am a front end designer not a coder..lol). The only changes I can make is CSS, js.
What I am tring to do:
I got the url on the page like this:
www.test.com/#box1#box3#box5
(I am not sure if I can have more than one ID in a row. please advice. However thats how the developer has done it and I dont mind as there are no issues yet)
the page html
<div id="box1"></div>
<div id="box2"></div>
<div id="box3"></div>
<div id="box4"></div>
<div id="box5"></div>
I would like to take different ids from the URl and use it to hidhlight the divs with that ID (by addding a class name "highlight")
The result should be like this:
<div id="box1 highlight"></div>
<div id="box2"></div>
<div id="box3 highlight"></div>
<div id="box4"></div>
<div id="box5 highlight"></div>
I would like to learn the smart way of taking just the id numbers from the url and use it to select the div with that paticulat no.
just a quick explanation:
var GetID = (get the id from the URL)
$('#box' + GetID).addClass('highlight');
Try This...
var hashes =location.hash.split('#');
hashes.reverse().pop();
$.each(hashes , function (i, id) {
$('#'+id).addClass('highlight');
});
Working fiddle here
var ids = window.location.hash.split('#').join(',#').slice(1);
jQuery(ids).addClass('highlight');
or in plain JS:
var divs = document.querySelectorAll(ids);
[].forEach.call(divs, function(div) {
div.className = 'highlight';
});
There are various way to resolve this issue in JavaScript. Best is to use "split()" method and get an array of hash(es).
var substr = ['box1','box2']
// Plain JavaScript
for (var i = 0; i < substr.length; ++i) {
document.getElementById(substr[i]).className = "highlight"
}
//For Each
substr.forEach(function(item) {
$('#' + item).addClass('highlight')
});
//Generic loop:
for (var i = 0; i < substr.length; ++i) {
$('#' + substr[i]).addClass('highlight')
}
Fiddle - http://jsfiddle.net/ylokesh/vjk7wvxq/
Updated Fiddle with provided markup and added plain javascript solution as well -
http://jsfiddle.net/ylokesh/vjk7wvxq/1/
var x = location.hash;
var hashes = x.split('#');
for(var i=0; i< hashes.length; i++){
var GetID = hashes[i];
//with jQuery
$('#box' + GetID).addClass('highlight');
//with Javascript
document.getElementById('box' + GetID).className = document.getElementById('box' + GetID).className + ' highlight';
}

Output html tag as text into a div, each array element on separate line

I have an array in javascript file called newElements.
The format likes this:
newElements: Array[3]
0: "<p class='Day'>asdasd</p>"
1: "<p class='Day'>123123</p>"
2: "<p class='Day'>Test</p>"
length: 3
And I have a div.panel-body.
What I did is
for( var i = 0; i < newElements.length; i++) {
new_content += newElements[i];
}
$(".panel-body").text(new_content);
It gives me output looks like this:
However, I want the div format like this:
<p class="Day">Some Text</p>
<p class="Day">Another Text</p>
<p class="Session">TEXT</p>
Each html tag on a separate line.
Yes, I know the <br> tag, but the question is, if I add <br> , the <br> tag will be treated as plain text, the output will become like this: <p class="Day">asdasd</p><br><p class="Day">asds</p>
So, could someone give me a nice way to show the output to screen the way I want it. You already have the array I give you.
And if I use html() function, the <p> will be treated as real html tag, that's not what I want, I want they be shown.
If you don't want to display the code, instead of .text(), use .html().
Fiddle: http://jsfiddle.net/q4AeR/
My mistake. Since you DO want to show the actual code, add each to its own new element, within the loop. This is the best I can think of:
Fiddle: http://jsfiddle.net/Hb9mC/
Try
for( var i = 0; i < newElements.length; i++) {
$(".panel-body").append(document.createTextNode(newElements[i])).append('<br/>');
}
http://jsfiddle.net/9z3zE/1/
I assume you want to display your code including line breaks. Convert your HTML to entities and add line breaks:
function htmlEntities(str) {
return String(str).replace(/&/g, '&').replace(/</g, '<').replace(/>/g, '>').replace(/"/g, '"');
}
var newElements = ['<p class="Day">asdasd</p>,<p class="Day">123123</p>,<p class="Day">Test</p>'],
output = '';
for(var i = 0; i < newElements.length; i++) {
output += htmlEntities(newElements[i]) + '<br />';
}
$('.panel-body').html(output);

how to convert div data into array using javascript or jquery?

I want to convert this code into an array.
<div id="Parent">
<div class="childOne" ><span id="1dfgdffsf">ChildOne </span></div>
<div class="childOne" ><span id = "2sdfsf">ChildTwo</span> </div>
<div class="childOne" ><span id="3sdfsf">ChildThree </span></div>
<div class="childOne" ><span id="4dssfsf">ChildFour </span></div>
</div>
span id is dynamic. therefore i can't use it.please tell me how to convert it into an array.
You will have to loop over each element and push it into an array
//declare an array
var my_array = new Array();
//get all instances of the SPAN tag and iterate through each one
$('div#parent div.childOne span').each(function(){
//build an associative array that assigns the span's id as the array id
//assign the inner value of the span to the array piece
//the single quotes and plus symbols are important in my_array[''++'']
my_array[''+$(this).attr('id')+''] = $(this).text();
//this code assigns the values to a non-associative array
//use either this code or the code above depending on your needs
my_array.push($(this).text());
});
If you do not use a library, the following should work fine:
var result = [], matches = document.querySelectorAll("#Parent span");
for (var i = 0, l = matches.length; i < l; i++)
result.push(matches[i].getAttribute("id"));
Else if the document.querySelectorAll function is not supported:
var result = [], parent = document.getElementByID("Parent");
for (var i = 0, l = parent.childNodes.length; i < l; i++)
result.push(parent.childNodes[i].childNodes[0].getAttribute("id"));
If you wanted to get key/value pairs instead you can do the following:
var result = [], matches = document.querySelectorAll("#Parent span");
for (var i = 0, l = matches.length; i < l; i++)
result[matches[i].getAttribute("id")] = matches[i].text;
With jQuery it is as simple as a single line of code:
var result = $("#Parent span").map(function() { return $(this).attr("id"); }).get();
First of all, try to avoid naming id's and classes from capital letters.
Then try this:
var arr = [];
$('#parent').children().each(function(){
arr.push($(this).find('span').text());
}
maybe this is the best way currently
const array = Array.from(document.querySelectorAll('.childOne'));
Below Code May be help you :
<!DOCTYPE html>
<html>
<head>
<style>
div { color:red; }
</style>
<script src="http://code.jquery.com/jquery-1.9.1.js"></script>
</head>
<body>
<div>First</div>
<div>Second</div>
<div>Third</div>
<div>Fourth</div>
<script>
var elems = document.getElementsByTagName("div"); // returns a nodeList
var arr = jQuery.makeArray(elems);
arr.reverse(); // use an Array method on list of dom elements
$(arr).appendTo(document.body);
</script>
</body>
</html>
This would be simple one, as :
jQuery(function($) {
var anArray = [];
$("#Parent").find("span").each(function(){
anArray.push($(this).html());
});
alert(anArray);
});
