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>

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.
I need to verify if a DIV has some text or not inside of it BUT NOT inside its children, eg see this example
<div id='one'>
<div id='two'>Abc</div>
</div>
<div id='three'>xyz
<div id='four'></div>
</div>
If I hover/click element one I want to get false (no text), but if i hover element three I want to get true
i tried using
$('#one').text().trim().length > 0
but it seems to check also any children which is want I do not want to happen
This is already answered here: jquery - get text for element without children text
Also mentions using a plugin to accomplish getting only the text of the element and not child elements here: http://viralpatel.net/blogs/jquery-get-text-element-without-child-element/
This meets your requirements
window.onload=function(){
var two = document.getElementById('two').textContent;
console.log(two.trim()=='');
var three = document.getElementById('three').textContent;
console.log(three.trim()=='');
}
<div id='one'>
<div id='two'>Abc</div>
</div>
<div id='three'>
<div id='four'></div>
</div>
In JavaScript I want to use document.querySelector to "grab" the last div (<div class="widget-footer">) in below HTML. However after many tries, I still can't figure out the correct CSS selector syntax to use.
The following code does not work:
document.querySelector (".skin-grid-widgets.ui-sortable.gridWidgetTemplatePositie.AgendaStandaard.disablesorting.hoogte-1-knoppen-0.breedte-1.widget-footer")
Here is the HTML I am working with
<div class="skin-grid enkeleKolom" id="Infobalk">
<div class="skin-grid-widgets ui-sortable">
<div class="gridWidgetTemplatePositie AgendaStandaard disablesorting hoogte-1-knoppen-0 breedte-1">
<div class="widget-header">
here comes the header text
</div>
<div class="widget-body">
some body text
</div>
<div class="widget-footer">
here comes the footer text
</div>
</div>
</div>
</div>
I've surfed everywhere to find example of complex CSS selectors used with querySelector, but to no avail. Any help would be really appreciated.
Your issue is you need a space in between each child element you are trying to select. If you do not have spaces in between your class selectors, by CSS specification, it will look for both classes on the same element.
Change your selector to look like the following:
var footer = document.querySelector(".skin-grid-widgets.ui-sortable .gridWidgetTemplatePositie.AgendaStandaard.disablesorting.hoogte-1-knoppen-0.breedte-1 .widget-footer");
footer.classList.add("highlight");
.highlight {
background-color: yellow;
}
<div class="skin-grid enkeleKolom" id="Infobalk">
<div class="skin-grid-widgets ui-sortable">
<div class="gridWidgetTemplatePositie AgendaStandaard disablesorting hoogte-1-knoppen-0 breedte-1">
<div class="widget-header">
here comes the header text
</div>
<div class="widget-body">
some body text
</div>
<div class="widget-footer">
here comes the footer text
</div>
</div>
</div>
</div>
try this:
<script>
document.querySelector (".skin-grid-widgets .gridWidgetTemplatePositie .widget-footer");
</script>
You don't need to add adjacent classes like "skin-grid-widgets ui-sortable" in querySelector, if you do so then query selector assumes that "skin-grid-widgets" is parent of "ui-sortable". Use just one of the classes at one DOM level.
The selector ain't complex, your thoughts are.
Listen to yourself, to the description you provide of what you want to select:
"grab" the last div in below HTML
Not grab the node with the class widget-footer inside of a node that has all these classes: gridWidgetTemplatePositie AgendaStandaard disablesorting hoogte-1-knoppen-0 breedte-1, inside a node ...
//a utility, because DRY.
//and because it's nicer to work with Arrays than with NodeLists or HTMLCollections.
function $$(selector, ctx=document){
return Array.from(ctx.querySelectorAll(selector));
}
//and the last div in this document:
var target = $$('div').pop();
or
"grab" <div class="widget-footer"> in below HTML
var target = document.querySelector("div.widget-footer");
or the combination: grab the last div.widget-footer in the HTML
var target = $$('div.widget-footer').pop();
I am using jsoup to parse an html document. I need to extract all the child div elements. This is basically div tags without nested div tags. I used the following in java to extract div tags,
Elements bodyTag = document.select("div:not(div>div)");
Here is an example:
<div id="header">
<div class="container">
<div id="header-logo">
<a href="/" title="mekay.com">
<div id="logo">
</div> </a>
</div>
<div id="header-banner">
<div data-type="ad" data-publisher="lqm.j2ee.site" data-zone="ron">
</div>
</div>
</div>
</div>
I need to extract only the following:
<div id="logo">
</div>
<div data-type="ad" data-publisher="lqm.j2ee.site" data-zone="ron">
</div>
Instead, the above code snippet is returning all the div tags. So, could you please help me figure out what is wrong with this selector
This one is perfectly working
Elements innerMostDivs = doc.select("div:not(:has(div))");
Try it online
add your html file
add css query as div:not(:has(div))
check resulted elements
If you want only div leafs that do not have any children then use this
Elements emptyDivs = document.select("div:empty");
The selector you are using now means fetch me all the divs that are not direct children of another div. It is normal that it brings the very first parent div, because the div id="header" is not a direct child of a div. Most likely its parent is body.
I like the usage of append in D3, and I'm looking for prepend.
Does this exist in D3?
You can use
selection.insert(newElement[, anotherExistingElement])
For example:
selection.insert("div",":first-child")
The above code will insert a div before the first child of selected element. Check documentation to learn more.
Another possible way of inserting elements before any node (including plain texts):
var parentEl = d3.select("div").node();
parentEl.insertBefore(document.createElement("div"), parentEl.childNodes[0]);
<script src="https://d3js.org/d3.v3.min.js"></script>
<div>
This is a plain text
<a></a>
</div>
Selection.lower()
selection.lower() will place an element as the first child of its parent.
Together with d3's append, selection.append().lower() can replicate jQuery's prepend
Since D3 v4+, D3 has both selection.raise() and selection.lower() methods. These are used most frequently to move elements in an SVG so that certain elements appear overtop of others, where ordering of SVG elements in the DOM determines draw order. But, they can be used for any element in the DOM.
Here's a quick demonstration using divs and paragraphs:
var div = d3.select("div");
div
.append("p")
.text("Inserted")
.lower();
console.log(div.html());
<script src="https://cdnjs.cloudflare.com/ajax/libs/d3/5.7.0/d3.min.js"></script>
<div id="div">
Text
<p> Child Paragraph </p>
</div>
The snippet takes a div with the following contents:
Text
<p> Child Paragraph </p>
And uses d3 to append a new paragraph and then lower it so that the structure is as follows:
<p>Inserted</p>
Text
<p> Child Paragraph </p>
And for comparison with with jQuery's prepend:
var div = $("div");
div
.prepend("<p>Inserted</p>");
console.log(div.html());
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div id="div">
Text
<p> Child Paragraph </p>
</div>
More Info
The selection.lower() is implemented as such (see docs for more info):
selection.each(function() {
this.parentNode.insertBefore(this, this.parentNode.firstChild);
});
