How to get value from children element using javascript [duplicate] - javascript

Getting HTML elements by their attribute names
(8 answers)
Closed 3 years ago.
I have html page with elements:
<div id="location-id" class="form-control">
<span class="hub-trigger" data-hub-recordid="28">Germany</span>
</div>
I use var element= document.getElementById('location-id') to get html element.
Please tell me how can i get 28 from the span ?
I have tried to use var id = element.getElementByTagName('data-hub-recordid') with val(), text(), innerText() at the end but it didn't work as i expected.

Try it
document.querySelector('.hub-trigger').getAttribute('data-hub-recordid')
or it
const parent = document.querySelector('#location-id');
const child = parent.querySelector('.hub-trigger');
const recordid = child.getAttribute('data-hub-recordid');

How Can I Use The HTML Button Element In JavaScript Completely [duplicate]

Why is document.write considered a "bad practice"?

Can You help me find out how to use the html button element in JavaScript because
document.write("<body> <div> </div> </body>")
is not working for buttons or drop down menus so can you help me?
my guess is the
.write
Is the problem because that probably means text and a button is not text.
This is not the most correct way to do this. You must create elements and add them to the DOM tree.
let button = document.createElement('button');
document.body.append(button);
button.onclick = () => {
alert('button clicked');
}
I think you want append(). This example is stolen from this MDN page
let parent = document.createElement("div")
let p = document.createElement("p")
parent.append(p)
console.log(parent.childNodes) // NodeList [ <p> ]

How to make and edit an Html div in javascript [duplicate]

Dynamically creating HTML elements using Javascript?

Closed 2 years ago.
Trying to make an Html div inside a div that is already made using javascript but my function has a problem.
Html part
<div id="test">
<button onclick="addDiv()">test</button>
</div>
Js part
let page = document.querySelector('test');
function addDiv() {
document.createElement('div')
document.querySelector('page')
addedDiv = document.appendChild('div')
page = document.appendChild('div')
document.getElementById('div').innerHTML = "ThisFunctionIsWorking"
}
the output should be seen in the console with a text inside the div that says ThisFunctionIsWorking
but instead I get an error(Failed to execute 'appendChild' on 'Node': parameter 1 is not of type 'Node'.)
I would appreciate your time helping me...
Your code is incorrect in many ways. I suggest you study basic (web) programming with the emphasis on fundamentals like return values, scope, etc. and then basic javascript and dom tree manipulation.
A solution to your problem is:
<div id="test">
<button onclick="addDiv('test')">test</button>
</div>
function addDiv(nodeId) {
var elem = document.createElement('div')
var container = document.getElementById(nodeId)
container.appendChild(elem)
elem.innerHTML = "ThisFunctionIsWorking"
}

jQuery selector for id starts with specific text [duplicate]

Closed 4 years ago.
Trying to get some help on some JavaScript we are trying to post accross multiple landing pages. We are sending values to hidden fields on a button click 'lp-pom-button-3'.
However, the ID changes depending on the page, but will always have the format 'lp-pom-button-' with the number potentially changing depending on the page. Is there a function similar to 'like' in SQL, or saying any button that starts with or contains 'lp-pom-button-" for this to be triggered on? Thanks for you help!
<script type="text/javascript">
document.getElementById('lp-pom-button-3').addEventListener(
'click', function(event) {
ga(function() {
var tracker = ga.getAll()[0];
var clientId = tracker.get('clientId');
document.getElementById('GACLIENTID').value = clientId;
var userId = tracker.get('userId');
document.getElementById('GAUSERID').value = userId;
});
});
You can use the css selector for attribute value contains.
[id*="lp-pom-button-"]
or attribute value starts with:
[id^="lp-pom-button-"]
In vanilla javascript you can access elements using css selector with querySelector or for getting a list of elements querySelectorAll.
Here is an example:
document.querySelector('[id^="lp-pom-button-"]');
And HERE is a list of all the browsers and browsers version that support this function.

How to call multiple elements by class and .innerHTML? [duplicate]

This question already has answers here:
What do querySelectorAll and getElementsBy* methods return?
(12 answers)
Closed 6 years ago.
I am having problems calling multiple elements with the same class name when using .innerhtml. For instance the url I am working with is:
https://www.amazon.com/s/ref=nb_sb_noss_2?url=search-alias%3Daps&field-keywords=hen
and when I enter the following code in chrome console I get:
document.getElementsByClassName('a-size-small a-color-secondary')
<span class="a-size-small a-color-secondary">by </span>
<span class="a-size-small a-color-secondary">Adore Plush Company</span>
<span class="a-size-small a-color-secondary">Get it by <span class="a-color-success a-text-bold">Tuesday, Jun 21</span></span>
...
...
But when I enter: document.getElementsByClassName('a-size-small a-color-secondary').innerHTML
I get "undefined". The goal is to get just the text between the span tags.
Can someone give me some guidance? I have tried with different variations including var and even Selection method. It worked with Selection for the first class element but didn't work at all with SelectionAll. Thanks for any help.
document.getElementsByClassName('a') will give the Object with class name .
for example class name is a and there are many spans with a , then you need get the span value by using index of that object
var x =document.getElementsByClassName('a');
console.log("value of spans"+x[0].innerHTML);

JS how right replace element? [duplicate]

jQuery if div contains this text, replace that part of the text

Closed 8 years ago.
...
<div>
<div>
{FirstName} {POSITION}
</div>
</div>

We would like find element {FirstName} and repalce him on test.
For this we make:
$("{FirstName}").replaceWith("test");
But it is not working...
Tell me please how right make replace?
What you should do is target the parent DIV (lets pretend it has a class of .test)
var content = $('.test').html();
var new_content = content.replace('{Whatever}', 'Hello');
$('.test').html(new_content);
Or in short (I haven't tested this, but it should work)
$('.test').html($('.test').html().replace('{Whatever}', 'Hello'));
If you just want to replace a string in DOM elements, the question has been asked before :
Replace all strings in dom element
But best to do this would be to use a template engine.
