how do you make it in javascript on page load like, if div1 equals YES then div2 must display "You Said YES"
<div class="div1">YES</div>
<div class="div2"></div>
If you want it in plain javascript, you can use body.onload like this:-
HTML:-
<body onLoad="onbodyload()">
<div id="div1">YES</div>
<div id="div2"></div>
</body>
Javascript:-=
function onbodyload(){
var d1 = document.getElementById('div1');
var d2 = document.getElementById('div2');
if(d1.innerHTML==='YES'){
d2.innerHTML='You Said Yes!';
}
};
Plunkr here.
Use onload event of body and do desired operation. Add id to the div for easy manipulation.
document.body.onload=function(){
//first element with class div1
var div1=document.getElementsByClassName('div1')[0];
if(div1.innerHTML=="YES"){
//first element with class div2
document.getElementsByClassName('div2')[0].innerHTML="You said Yes";
}
}
<body>
<div class="div1" id="div1">YES</div>
<div class="div2" id="div2"></div>
</body>
$('.div2').show().text("You said yes!");
$(function() {
if ($('.div1').text() == "YES") {
$('.div2').text("You said yes!");
}
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div class="div1">YES</div>
<div class="div2"></div>

You can use the second argument of the jQuery selector $() to specify the context. This way you'll find all elements which match the selector which are descendants of temp (ie the context):
var temp = $('#temp');
$('button').on('click', function() {
temp.html($('#wrap').html());
$('.elmark', temp).removeClass('elact');
});
.elact {
background: yellow;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<button>CLICK</button>
<div id='wrap'>
<div class='elmark elact'>R</div>
</div>
<div id='temp'></div>
hi I'm trying to target a button to a div using iframe .. I tried so much but no result...

document.write("someword");
}
it seems true but when I click the button it open a blank page showing what in the function.. help ??
You are missing alot,
First do not practice "onclick()" anymore.
Second do not practice "document.write" anymore.
I have rewrite your code, enjoy..
HTML
<div id="one">
<button type="submit" id="functionThis" formtarget="result"> Calculate </button>
</div>
<div id="two">
<iframe id="iframe1" name="result"></iframe>
</div>
JS
document.getElementById("functionThis").addEventListener("click", showResult, false);
function showResult() {
var htmlString = "<body>Some Words</body>";
var myIFrame = document.getElementById('iframe1');
myIFrame.src = "javascript:'" + htmlString + "'";

Hello everybody I would like to hide some divs and display others when I click on a specifiks links.
Actually I did like this :
<html>
<head>
<script>
function loadA(){
document.getElementById("A").style.display="block";
document.getElementById("B").style.display="none";
document.getElementById("C").style.display="none";
document.getElementById("D").style.display="none";
}
function loadB(){
document.getElementById("A").style.display="none";
document.getElementById("B").style.display="block";
document.getElementById("C").style.display="none";
document.getElementById("D").style.display="none";
}
function loadC(){
document.getElementById("A").style.display="none";
document.getElementById("B").style.display="none";
document.getElementById("C").style.display="block";
document.getElementById("D").style.display="none";
}
function loadD(){
document.getElementById("A").style.display="none";
document.getElementById("B").style.display="none";
document.getElementById("C").style.display="none";
document.getElementById("D").style.display="block";
}
</script>
</head>
<body>
<div class="menu">
A
B
C
D
</div>
</body>
</html>
This is work with me but as you see it's not a good practice and sure there is another way better than this , can you show me please !
A solution without javascript:
.container > div{
display:none
}
.container > div:target{
display:block
}
<div class="menu">
<a href="#A" >A</a>
<a href="#B" >B</a>
<a href="#C" >C</a>
<a href="#D" >D</a>
</div>
<div class="container">
<div id="A" >A content</div>
<div id="B" >B content</div>
<div id="C" >C content</div>
<div id="D" >D content</div>
</div>
https://developer.mozilla.org/en-US/docs/Web/CSS/%3Atarget
https://css-tricks.com/css3-tabs/
You can create one function and reuse it for each element:
function loadDiv(id){
document.getElementById("A").style.display="none";
document.getElementById("B").style.display="none";
document.getElementById("C").style.display="none";
document.getElementById("D").style.display="none";
document.getElementById(id).style.display="block";
}
And pass the correct id into each onclick:
<div class="menu">
A
B
C
D
</div>
Here's how you should do it. No inline javascript, handling click events with an eventListener and wrapping all elements together with a class, making it much less code to write and maintain:
JS:
function divLoader(e){
var hide = document.getElementsByClassName("hideAndShow");
for (var i = 0; i<hide.length;i++) {
hide[i].style.display="none";
}
document.getElementById(e.target.getAttribute('data-link')).style.display="block";
}
var anchors = document.querySelectorAll('.menu > a');
for (var i = 0; i<anchors.length; i++) {
anchors[i].addEventListener('click',divLoader);
}
HTML:
<div class="menu">
A
B
C
D
</div>
<div id="A" class="hideAndShow" style="display:none;">A</div>
<div id="B" class="hideAndShow" style="display:none;">B</div>
<div id="C" class="hideAndShow" style="display:none;">C</div>
<div id="D" class="hideAndShow" style="display:none;">D</div>
In such cases where you have similar repetitive code you can use a common technique called "Abstraction". The main idea is the turn the common code into parameters of a single function in your case it would be:
function loadByID(id){
document.getElementById("A").style.display="none";
document.getElementById("B").style.display="none";
document.getElementById("C").style.display="none";
document.getElementById("D").style.display="none";
document.getElementById(id).style.display="block";
}
However this is also still a little bit redundant, for larger menus and displaying multiple links you can do something like
function loadByIDs(ids){
var links = document.getElementsByTagName("a");
for(var i = 0; i < links.length; i++){
document.getElementById(links[i].id).style.display = none;
}
for each(var id in ids){
document.getElementById(id).style.display = block;
}
}
This will work much better when you have too much links and want to display more than one link at a time (so you will need to pass in an array)
Note: If you are using Jquery you can just use .each() function to get rid of the first for loop
Hope this helps!
I think the best practice in your case is to define a general function that work however the number of links with specific class in my example the class is link, take a look at Working Fiddle.
Now your script will work with dynamic links added in div, you have just to add html without touching the js will detect change.
HTML :
<div class="menu">
A
B
C
D
</div>
JS :
load = function(e){
//select all links
var links = document.getElementsByClassName('link');
//Hide all the links
for (i = 0; i < links.length; i++) {
links[i].style.display = "none";
}
//Show clicked link
e.target.style.display = "block";
}
Hope this make sens.
HTML
<body>
<div id="main">
<ul id="nav">
<li>Home</li>
<li>About Us</li>
</ul>
<div id="container">
<div id="wrapper">
<div class="content">
<div id="menu_home">
<h2>Menu 1</h2>
</div>
<div id="menu_about">
<h2>Menu 2</h2>
</div>
</div><!--content-->
</div><!--wrapper-->
</div><!--container-->
</div><!-- main-->
</body>
JS
$(document).ready(function(){
$("#menu_home").slideUp("fast");
$("#menu_about").slideUp("fast");
$("#menu_home").show();
$("#nav a").click(function(){
var id = $(this).attr('id');
id = id.split('_');
$(".content div").slideUp("fast");;
$(".content #menu_"+id[1]).slideToggle("fast");
});
});
Here is the example
function loadA()
{
document.getElementById("A").style.visiblity="show";
document.getElementById("B").style.visiblity="hide";
document.getElementById("C").style.visiblity="hide";
document.getElementById("D").style.visiblity="hide";
}
if visibility dont work,just change the visibility keyword with visible and hide with hidden.
and one more thing,u should not write function for each div..what can u do just pass id of a div which u want to show and hide others..see below
function trigger(id)
{
var alldiv={"A","B","C","D"};
for(i=0;i<alldiv.length;i++)
{
if(alldiv[i]==id)
document.getElementById(id).style.visiblity="show";
else
document.getElementById(alldiv[i]).style.visiblity="hide";
}
}
I am trying to change the css stylings of an item when it's clicked.
ryan.js
function ryanClicked(id){
document.getElementById(id).style.color = "blue";
alert("Asdsa");
}
product.html
<head>
<script src="ryan.js"></script>
</head>
<body>
<div id ="sizeButton1"class="sizeButton" onclick="ryanClicked(sizeButton1)"> S </div>
<div id ="sizeButton2"class="sizeButton" onclick="ryanClicked(sizeButton2)"> M </div>
<div id ="sizeButton3"class="sizeButton" onclick="ryanClicked(sizeButton3)"> L </div>
I assume I need a onReady or onLoad somewhere? I haven't done js in a while.
My page has Jquery included so I can use jquery for the ready event. I'm not sure if that would be better to do or not.
Try this, you don't need pass id to your function, instead you can pass this (refers to element that was clicked),
function ryanClicked(el) {
el.style.color = "blue";
}
<div id="sizeButton1"class="sizeButton" onclick="ryanClicked(this)">S</div>
<div id="sizeButton2"class="sizeButton" onclick="ryanClicked(this)">M</div>
<div id="sizeButton3"class="sizeButton" onclick="ryanClicked(this)">L</div>
If you are using jQuery, you might prefer:
<div id ="sizeButton1" class="sizeButton"> S </div>
<div id ="sizeButton2" class="sizeButton"> M </div>
<div id ="sizeButton3" class="sizeButton"> L </div>
and:
$(".sizeButton").on("click", function() {
$(this).css("color", "blue")
})
https://jsfiddle.net/38ybvty8/
You can get desired result without passing id and onclick attribute in your element tag.
$(".sizeButton").click(function(){
$(this).css({'color':'blue'});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id ="sizeButton1" class="sizeButton" >S </div>
<div id ="sizeButton2" class="sizeButton" >M</div>
<div id ="sizeButton3" class="sizeButton" >L</div>
When I click on the div, it should open. When I click again, it should close the div. Please help me on this.
<html>
<head>
<script type="text/javascript">
var bool = 0;
function showDiv(){
if(bool==1){
bool=0;
document.getElementById(show).style.visibility = "hidden";
}else if(bool==0){
bool=1;
document.getElementById(show).style.visibility = "visible";
}
}
</script>
</head>
<body>
<input type="button" value="click" onclick="showDiv();" />
<div="show">
<p>it is okay it is okay it is okay it is okay it is okay it is okay it is okay it is okay</p>
</div>
</body>
</html>
You're missing the quotes for the id argument for getElementById()
document.getElementById('show').style.visibility = "hidden";
Also the id attribute name is missing on the <div>
<div="show">
Should be this:
<div id="show">
jsFiddle
Try this:
HTML
<button id="myButton">Show DIV</button>
<div id="show" class="hidden">
<p>it is okay </p>
</div>
CSS
.hidden
{
display:none;
}
JS
$('#myButton').click(function () {
$("#show").slideToggle();
$(this).text($(this).text() == 'Show DIV' ? 'Hide DIV' : 'Show DIV');
return false;
});
Here's the jsfiddle: http://jsfiddle.net/mgrcic/RbjLJ/
When you are referring to
document.getElementById(show).style.visibility
The show refers to a variable, but you are trying to get it as a string, so you should get it quoted
document.getElementById('show').style.visibility
You are writing the div wrong. You should put "show" as the value of your Id attribute:
<div id="show"> </div>
If you use jQuery (you tagged it), why not use jQuery to get things done more cleanly, in an unobtrusive way ?
$(function(){
var bool = 0;
$("input[type='button']").click(function(){
if(bool ==0)
{
bool =1
$("#show").hide();
}
else
{
bool =0
$("#show").show();
}
});
});
Here is the sample: http://jsfiddle.net/sHsuh/10/
Note that this script will bind the function to all button elements in your page. So I would be more specific by adding an Id to my Button and bind with that:
$("#myButtonId").click(function(){
//code goes here
});
Here is the solution, you couldn't get your element without specifying div id="theid":
<html>
<head>
<script type="text/javascript">
var bool = 0;
function showDiv(){
var elem = document.getElementById('show');
console.log(elem);
if(bool==1){
bool=0;
elem.style.visibility = "hidden";
}else if(bool==0){
bool=1;
elem.style.visibility = "visible";
}
}
</script>
</head>
<body>
<input type="button" value="click" onclick="showDiv();" />
<div id="show">
<p>it is okay it is okay it is okay it is okay it is okay it is okay it is okay it is okay</p>
</div>
</body>
</html>
You have made some mistakes:
<div="show"> is wrong. The correct way is <div id="show">.
If you want show and hide means, first set your div's CSS to visibility:hidden;.
You are missing an apostrophe in document.getElementById('show');.
Try this:
<html>
<head>
<script type="text/javascript">
var bool = 0;
function showDiv(){
if(bool==1){
bool=0;
document.getElementById('show').style.visibility = "hidden";
}else if(bool==0){
bool=1;
document.getElementById('show').style.visibility = "visible";
}
}
</script>
</head>
<body>
<input type="button" value="click" onclick="showDiv();" />
<div id="show" style=" visibility:hidden;">
<p>it is okay it is okay it is okay it is okay it is okay it is okay it is okay it is okay</p>
</div>
</body>
</html>
