I need to write this in Javascript but I'm a noob. Already looked for help on www.w3schools.com but it seems it will take an era to find out this simple answer.

You can simply loop through all a tags and hide the one with the href you want.
您可以简单地遍历所有标记并隐藏具有所需href的标记。
$('a').each(function(){
if($(this).attr('href') == "http://www.mysite.com.br")
{
$(this).css('display',"none");
}
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<a href="http://example.com">Example</a>
<a href="http://www.mysite.com.br">this should be hidden</a>
<a href="http://example2.com">Example 2</a>
<a href="http://example3.com">Example 3</a>

If you do not use jQuery then use the core JS approach:
如果你不使用jQuery,那么使用核心JS方法:
var elements = document.querySelectorAll('a[href="http://www.mysite.com.br"]');
for (var i = 0; i < elements.length; ++i) {
elements[i].style.display = "none";
}
<a href="http://example.com">Example</a>
<a href="http://www.mysite.com.br">this should be hidden</a>
<a href="http://example2.com">Example 2</a>
<a href="http://example3.com">Example 3</a>

You should select the result using a query selector. Assuming you want to use vanilla js and not jquery it will be something like:
您应该使用查询选择器选择结果。假设您想要使用vanilla js而不是jquery,它将类似于:
var elements = document.querySelectorAll('a[href="yoursite"]');
and then loop over the results:
然后遍历结果:
for (var i = 0; i < elements.length; ++i) {
elements[i].style.display = "none";
}
Hope this helps.

You could use the CSS [attribute=value] Selector
您可以使用CSS [attribute = value]选择器
a[href="http://www.google.de/"] {
color: red;
}
<p>
Hello
</p>
<a href="http://www.google.de/">Hello</a>
<span>Hello</span>

First select your a tag
using document.querySelector
then using getAttribute()
check whether it consist of any url
or not, if true then hide a tag
, as below,
首先使用document.querySelector选择一个标签,然后使用getAttribute()检查它是否包含任何url,如果为true则隐藏标签,如下所示,
var a = document.querySelector("a");
var b = a.getAttribute("href");
console.log(b);
if(b == "http://www.mysite.com.br"){
a.style.display = "none";
}
<a href="http://www.mysite.com.br">Link</a>
