I have some simple code here, and I want to test it out, by making the display none, is there something wrong with my javascript? (I'm very new to js)
var meter = document.getElementById("meter").innerHTML;
meter.style.display = "none";
<meter id="meter" min="0" max="10"></meter>
The console says meter is undefined, but I defined it right above.
meter is the innerHTML of the element (which is a string), not the element itself.
Instead, use:
var meter = document.getElementById("meter");
meter.style.display = "none";
<meter id="meter" min="0" max="10"></meter>
If you want to hide it and get its value, you can do:
var meter = document.getElementById("meter");
meter.style.display = "none";
var val = meter.value;
console.log(val)
<meter id="meter" min="0" max="10" value="3"></meter>

I am trying to get the element itself through making a function in the div itself I want when someone clicks on the current Element the Element should be deleted by fading in pure JavaScript I have searched on the internet but not getting the answer there are many similar questions on Stack Overflow but none of them giving me the combined answer(Like getting current element through Js in (inline function)).
So anyone can help me
<div style="width: 100px;height: 100px;background:red;" onclick="(function(ele){
console.log('helo')
console.log(ele.currentTarget)})();">
Thanks in advance
This should do it:
I added an id to your div which can be accessed through the getElementById.
<div id='hello' style="width: 100px;height: 100px;background:red;" onclick="
(
function() {
document.getElementById('hello').style.opacity = 0;
document.getElementById('hello').style.transition = '0.5s';
}
)();">

I want to get the id from a class selector without clicking.
var type_selected = '' ;
$('.type_selected').attr();
type_selected = (this.id);
Use this. This will return an array of all elements with that class;
var type_selected = [];
$('.type_selected').each(function(){
type_selected.push($(this).attr("id"));
});
console.log(type_selected);
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<p class="type_selected" id="id1">This is a test<p>
<p class="type_selected" id="id2">This is a test 2<p>
<p class="type_selected" id="id3">This is a test<p>

I'm trying to do a basic math function and change the contents of a <p></p> element but when I click the button, it does nothing.
I know it's something trivial but I thought this would work.
What am I missing?
HTML
<button onclick="doMath()">Click</button>
<p id="output"></p>
JavaScript
function doMath() {
var total = 6/2(2+1);
document.getElementById("output").innerHTML = total;
}
function doMath() {
var total = (6/2*(2+1));
document.getElementById("output").innerHTML = total;
}
<button onclick="doMath()">Click</button>
<p id="output"></p>

I'm having here a <select> that looks like this:
<select id="stdin-select" class="io-byte-box" size="10">
<option>0x5232</option>
<option>0xFD13</option>
<option>0x13E7</option>
<option>0x1234</option>
<option>0xFFFF</option>
</select>
and I am trying to access the values by its index like this:
var stdinValue = $('.stdin-select.dropdown option').eq(0).text();
and this
var stdinValue = $('.stdin-select option').eq(0).text();
like described here but it's not working.
What am I doing wrong here?
Change class (.) to id ('#')
var stdinValue = $('#stdin-select option').eq(0).text();
In your example there is not element with class stdin-select, instead there is element with if stdin-select

I am trying to create an iframe in which the content changes based on a button click. However the iframe is not displaying any content. Could someone take a look at my code and explain why.
<script>
int i = 0;
var array= ["news1.html","news2.html","news3.html"];
function setURL(){
if (i<2) {
i = i+1;
}
else{
i=0;
};
document.getElementById("iframe").src = array[i];
}
</script>
<iframe id="iframe" style="float:right;" width="770" height="360"></iframe>
<button type="button" onclick="setURL()" style="float:right;"> Next </button>
I know it's not the best code in the world but as far as I can tell it should work so I was hoping for a hand with it please?
change your variable declaration from:
int i = 0;
to:
var i = 0;
Everything worked once i changed that.
