I am using this code to remove the href links from my page. It works great except I do not want to target all the links. Instead, I want to target all of the links within a div, like disable all the links of a particular div with an id "test2".
var all_links = document.getElementsByTagName("a");
for(var i=0; i<all_links.length; i++){
all_links[i].removeAttribute("href");
}
You can use querySelectorAll() for that. Pass a CSS selector that matches the elements you need to target. From what you have described, div#test2 a will do:
var all_links = document.querySelectorAll("div#test2 a");
for(var i=0; i<all_links.length; i++){
all_links[i].removeAttribute("href");
}
Or, for maximum compatibility (IE <9):
var all_links = document.getElementById('test2').getElementsByTagName("a");
There are a few options for this, here using ES6:
// retrieving all <a> elements within <div id="test2">, using
// document.querySelectorAll() and converting that collection
// into an Array, using Array.from():
var all_links = Array.from(document.querySelectorAll("div#test2 a"))
// iterating over that Array using Array.prototype.forEach(),
// along with an Arrow function to remove the 'href' attribute
// from each of the <a> elements in the Array:
.forEach(link => link.removeAttribute('href'));
var all_links = Array.from(document.querySelectorAll("div#test2 a")).forEach(link => link.removeAttribute('href'));<a href="#href1">Link 1</a>
<div id="test2">
<a href="#href2">Link 2</a>
<a href="#href3">Link 3</a>
</div>
<a href="#href4">Link 4</a>
<div id="test3">
<a href="#href5">Link 5</a>
<a href="#href6">Link 6</a>
</div>Or, rather than removing the href attribute setting it instead to the value of '#':
var all_links = Array.from(document.querySelectorAll("div#test2 a"))
// here we use setAttribute() to set the value of the href
// attribute to the '#' value:
.forEach(link => link.setAttribute('href', '#'));
var all_links = Array.from(document.querySelectorAll("div#test2 a")).forEach(link => link.setAttribute('href', '#'));<a href="#href1">Link 1</a>
<div id="test2">
<a href="#href2">Link 2</a>
<a href="#href3">Link 3</a>
</div>
<a href="#href4">Link 4</a>
<div id="test3">
<a href="#href5">Link 5</a>
<a href="#href6">Link 6</a>
</div>Or, given that an <a> element without an href attribute arguably serves no particular 'purpose' we could instead unwrap the text, or other contents, and remove the no-longer-useful <a> element:
var all_links = Array.from( document.querySelectorAll("div#test2 a") )
// using the anonymous function of Array.prototype.forEach() rather
// than Arrow functions, given the work being done here:
.forEach(function(link){
// while the <a> element has a firstChild:
while(link.firstChild) {
// we access the parentNode of the <a> and
// use the insertBefore() method to insert
// the firstChild of the <a> before the <a>:
link.parentNode.insertBefore(link.firstChild, link);
}
// once the <a> is emptied of its content,
// we again access the parentNode and remove
// the <a> element itself:
link.parentNode.removeChild(link);
});
var all_links = Array.from(document.querySelectorAll("div#test2 a")).forEach(function(link) {
while (link.firstChild) {
link.parentNode.insertBefore(link.firstChild, link);
}
link.parentNode.removeChild(link);
});<a href="#href1">Link 1</a>
<div id="test2">
<a href="#href2">Link 2</a>
<a href="#href3">Link 3</a>
</div>
<a href="#href4">Link 4</a>
<div id="test3">
<a href="#href5">Link 5</a>
<a href="#href6">Link 6</a>
</div>References:
As the jQuery tag is included:-
$('#test2 a').removeAttr('href');<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<a href="test">test</a>
<div id="test2">
<a href="test1">test</a>
<a href="test2">test</a>
</div>Since you have tagged this with jQuery you can use the following:
$("div#test2 a").removeAttr("href");
