A simple querySelectorAll()
should do the trick:
var check = document.querySelectorAll('.c [name="check"]');
And as stated in a comment already, only document
has getElementsByName
method.
Pregunta
I have some Divs:
<div id="content">
<div class="c" id="1">
<div id="xyz">dont care</div>
<div id="texts1">
<div name="check"> ContentText </div>
</div>
</div>
<div class="c" id="2">
<div id="xuyz">dont care</div>
<div id="texts2">
<div name="check"> ContentText </div>
</div>
</div>
</div>
I want to iterate through all elements of the "c" class. Then I want to check, if the Div elements named "check" of each "c" element contains special text.
If true, then manipulate the "c" element (which contains the special text)
I tried something like this:
var ele = document.getElementsByClassName("c");
for(var i=0;i<ele.length;i++)
{
var check = ele[i].getElementsByName("check");
if(check.innerHTML ....)
}
But thats not working :/ Log from Firefox:
TypeError: ele[i].getElementsByName is not a function
Where is my mistake?

With jQuery this is very simple -
$('[name="check"]:contains("your special text")')
With jQuery (you have tagged it with it as well)
$(document).ready(function () {
$('div.c').find('div[name="check"]').each(function(){
// here check HTML and do needed manipulations
if($(this).html() == 'ContentText'){
$(this).closest('div.c').children().first().html('I CARE');
}
});
});

Here is a modification of your code to make it work as intended
var ele = document.getElementsByClassName("c");
for (var i = 0; i < ele.length; i++)
{
if (ele[i].getAttribute('name') === "check") {
// do something with matching elements here
}
}
