I have a div with some text and a child div. I want to update the outer div text and keep the child div.
<div class="outer">
some text here
<div class="arrow-down"></div>
</div>
if I try outer.innerText = "foo" the arrow-down element is deleted. How can I get around this?
Thanks
Create a child element such as a span element and place the text you want change inside that.
Then you can update that via JavaScript like so:
var el = document.getElementById('inner');
el.innerText = 'some different text';
<div class="outer">
<span id="inner">some text here</span>
<div class="arrow-down"></div>
</div>

How to get all the HTML nodes having text in an optimal way without having to loop through every node?
In other words, grab all HTML nodes having visible text.
For example, if I have a dom as below
<div>
<span>Hello This is a Text Span</span>
<div>
<p> This is a text Paragraph</p>
<button> This is Button Label</button>
</div>
<div> This is also a visible text</div>
</div>
I should select
span having text Hello This is a Text Span
p having text This is a text Paragraph
button having text This is Button Label
div having text This is also a visible text
The outermost div in the above example doesn't have text of its own so should not be part of the result.
Edit: What problem am I trying to solve?
The framework I use escapes HTML characters in labels of fields, buttons, headings etc.
For example: < is converted to & lt;'
So I am trying to write a client side code which triggers after the page is completely rendered which will unescape all the HTML texts to a readable format.
Any help will be appreciated.
Thanks in advance
The DOM property holds a numeric code indicating the node's type; text nodes use the code 3, So you can find those text nodes by filtering them having nodeType 3.
Wrap your all nodes in a div by giving a class.
Select your content by it's class like this: $(".getTextNodes").contents();.
Filter contents having nodeType 3.
selectedElement = $(".getTextNodes").contents();
textNodes = selectedElement.filter(function() {
return this.nodeType === 3;
});
console.log(textNodes);

I'm using just only vanilla js
My algorithm is just select all element that has no element inside it
It means select all element that has directly Text Node
let el = document.querySelectorAll('div,span,p,button');
var arr = [];
el.forEach(function(m){
if (m.querySelectorAll('div,span,p,button').length == 0){
arr.push(m)
console.log(m)
}
})
// console.log(arr)
<div>
<span>Hello This is a Text Span</span>
<div>
<p>This is a text Paragraph</p>
<button> This is Button Label</button>
</div>
<div>This is also a visible text</div>
</div>

There's no css selector to get your needs and looping is only the solution.
return (
<div
onMouseUp={() => {
this.handleMouseUp();
this.showMenu();
}}
className="sectionWrite"
contentEditable="true"
>
<div>
<br></br>
</div>
{menuSelect}
</div>
);
Here is how the div appears after text is typed into the content editable div. For each child div inside the class sectionWrite, I want to name it a class.
<div class="sectionWrite" contenteditable="true">
<div>adfasdfasdf</div>
<div>asdlkfjasdlkjf</div>
<div>asdfkljasdlfkjasdlkfj</div>
<div>asdfkjasdlkfjasdf</div>
<div>aklsdjfaskldjfas</div>
<div>dfklasjdflkajdsf</div>
<div>lkasjdflkjasdf</div>
<div><br></div>
</div>
what I type inside the editable div
When a client types in the contentEditable div, a new div encloses whatever the user typed. Is there any way to assign a class name to the div the user typed? I want to display a menu under a highlighted text and I would need a specific dom element to do that.
I'd like to know how to create buttons which can change the content inside a div and if the last clicked button (actual content) is clicked again instead of change it should clear the div.
So far I got the code to create and change the content like this:
HTML
<button onclick="changeNavigation('bl1')">Techniker</button>
<button onclick="changeNavigation('bl2')">Übersetzer</button>
<button onclick="changeNavigation('bl3')">Qualitychecker</button>
<div id="text_content"></div>
<div id="bl1">
<p>This is text 1</p>
</div>
<div id="bl2">
<p>This is text 2</p>
</div>
<div id="bl3">
<p>This is text 3</p>
</div>
JS
function changeNavigation(id) {
document.getElementbyId('text_content').innerHTML= document.getElementbyId(id).innerHTML;
}
With this code so far I can make the content inside the div change by clicking the bottons. But once the box has been filex I can only change the inside content. If I click the button from the actual content again nothing happens but I'd like to clear the content.
Can maybe anyone explain me or link me the name of such a funtion?
Thanks in advance!
Im not really sure what you're trying to get here? If you click a nav item twice to clear the div?
If so try something like this
function changeNavigation(id) {
var textContent = document.getElementbyId('text_content'),
containerDiv = document.getElementbyId(id);
if(textContent.innerHTML === containerDiv.innerHTML){
textContent.innerHTML = '';
} else {
textContent.innerHTML = containerDiv.innerHTML
}
}
What we're doing here is checking if the text_content is the same value as the div you're getting the content from. if so then empty it.
I'm trying to get the div element that's nested deep within another div, but can't get the CSS Selector string to work.
The div I want does not have a unique identifier, but resides deep within another div that has. I've gotten that top level div, but have no clue how to get the nested one.
DOM:
var obj = document.body.querySelector('.qvobject[data-qlikobjectid="XFvnjF"]');
console.log(obj);
var cont = obj.querySelector('.kpi-value');
console.log(cont);
<div class="qvobject" data-qlikobjectid="XFvnjF">
<div>
<div>
<div class="kpi-value">I WANT THIS</div>
</div>
</div>
</div>
The result is that "obj" is the right object, but "cont" is null, so it can't find it.
You can select it using the child selector. Just put a space between the parent selector and the child selector.
This makes the traverser go further to any level in the dom to select the desired element.
var element = document.querySelector('.qvobject[data-qlikobjectid="XFvnjF"] .kpi-value');
console.log(element);
<div class="qvobject" data-qlikobjectid="XFvnjF">
<div>
<div>
<div class="kpi-value">I WANT THIS</div>
</div>
</div>
</div>

Using .text() to retrieve only text not nested in child tags
(30 answers)
Closed 5 years ago.
Could some one give me some guidance on what's the best way to do this.
I'm trying to get all the text which is after ".main"
I know this might be simple, but it's been picking at my brain all day just before Christmas. So i thought instead of stressing myself out, I would look for some guidance.
The example code only brings back the Text in P tag but i'd like to bring back Text not in it's own element and the p tag
console.log($("#container").find(".main").next().text());
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div id="container">
<div class="main"> WOOP IN MAIN </div>
Text not in it's own element
<p> Text in P tag </p>
</div>
The simplest way to achieve this is to clone() the container, remove the .main element from it, then get the text(), like this:
var text = $("#container").clone().find('.main').remove().end().text();
console.log(text.trim());
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div id="container">
<div class="main"> WOOP IN MAIN </div>
Text not in it's own element
<p> Text in P tag </p>
</div>
You could alternatively recursively traverse through the DOM nodes that follow the .main element, but this is much more complicated and gives the same result.
It's because Text not in it's own element is considered a text node, therefore next() will target the <p/> tag, being that it's an HTMLElement. If you were to go native you'd use a combination of nextSibling, which is agnostic of the two node types and nextElementSibling, which as it's method name implies, grabs the next sibling element:
const main = document.querySelector('.main');
const txt = [
main.nextSibling.textContent.trim(),
main.nextElementSibling.textContent.trim()
];
console.log(txt)
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div id="container">
<div class="main"> WOOP IN MAIN </div>
Text not in it's own element
<p> Text in P tag </p>
</div>
