im having trouble running javascript hide/show div using CSS classes, when i click on the trigger nothing happens. The relevant codes are the following:
HTML
Click
<div id="test" class="hidden">
test
</div>
CSS
.hidden{
display:none;
}
JS
function toggleClass(eid, myclass) {
var theEle = document.getElementById(eid);
var eClass = theEle.className;
if (eClass.indexOf(myclass) >= 0) {
theEle.className = eClass.replace(myclass, "");
} else{
theEle.className += "" +myclass;
}
}
two issues: you missed a "#" for the href + ' for the test and hidden (must be strings):
Click
<div id="test" class="hidden">
test
</div>
im not 100% certain, but im pretty sure you need to enclose the arguments in quotation marks
Click
<div id="test" class="hidden">
test
</div>

I would like to check if the text exist in the div element, so that if text matches the text in div it will alert "hello". May I know how am I able to achieve this result? Thank you.
<script type="text/javascript">
jQuery(document).ready(function(){
var text = "div[style*=\"width: 550px;\"]";
if (#content.indexOf(text) > -1){
alert("Hello");
}
});
</script>
<div id="content">
<div style="width:550px;">James</div>
<div style="width:500px;">Amy</div>
</div>
Here you go with a solution https://jsfiddle.net/9kLnvyqm/
if($('#content').text().length > 0) { // Checking the text inside a div
// Condition to check the text match
if($('#content').text().indexOf('Amy')){
console.log('Hello');
}
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="content">
<div style="width:550px;">James</div>
<div style="width:500px;">Amy</div>
</div>
If you want only the text content from a container then use text(), if you are looking for html content then use html().
Hope this will help you.
It is possible to get the value of inline style of an element.
var wid = $("#content > div")[0].style.width;
if(wid === "550px"){
//correct width detected. you can use alert instead of console.log
console.log("hello");
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="content">
<div style="width:550px;">James</div>
<div style="width:500px;">Amy</div>
</div>
You have multiple elements inside #content. you may want to use the return value of
$('#content').children().length;
and loop the program to get inline width of all elements. Ping if you need some help with the loop
I have some code I'm working on that toggles a div of information depending on the user clicking an image. What I'm looking for is assistance in getting the image to swap when the user clicks, then to swap back when it's clicked again. The image should be changing to: https://casetest.blackboard.com/bbcswebdav/users/kas200/collapse.gif
I'm a newbie when it comes to coding with JS, so any help provided would be much appreciated!
<script type="text/javascript">
function toggleMe(a){
var e=document.getElementById(a);
if(!e)return true;
if(e.style.display=="none"){
e.style.display="block";
}
else{
e.style.display="none";
}
return true;
}
</script>
<input type="image" src="https://casetest.blackboard.com/bbcswebdav/users/kas200/expand.gif" onclick="return toggleMe('para1')" value="Toggle"><br>
<div id="para1" style="display:none">
This is my text for section 1!
</div>
<br>
<input type="image" src="https://casetest.blackboard.com/bbcswebdav/users/kas200/expand.gif" onclick="return toggleMe('para2')" value="Toggle"><br>
<div id="para2" style="display:none">
This is my text for section 2!
</div>
<br>
<input type="image" src="https://casetest.blackboard.com/bbcswebdav/users/kas200/expand.gif" onclick="return toggleMe('para3')" value="Toggle"><br>
<span id="para3" style="display:none">
This is my text for section 3!
</span>
You've got the right idea. What I did for this case was add an id to each image with the name of the div + _img -- grabbed that element the same way, then updated the src:
javascript
function toggleMe(a){
var e=document.getElementById(a);
var i=document.getElementById(a+'_img');
if(!e)return true;
if(e.style.display=="none"){
i.src="https://casetest.blackboard.com/bbcswebdav/users/kas200/collapse.gif"
e.style.display="block"
}
else{
i.src="https://casetest.blackboard.com/bbcswebdav/users/kas200/expand.gif"
e.style.display="none"
}
return true;
}
html
<input type="image" src="https://casetest.blackboard.com/bbcswebdav/users/kas200/expand.gif" onclick="return toggleMe('para1')" value="Toggle" id="para1_img"><br>
<div id="para1" style="display:none">
This is my text for section 1!
</div>
<br>
<input type="image" src="https://casetest.blackboard.com/bbcswebdav/users/kas200/expand.gif" onclick="return toggleMe('para2')" value="Toggle" id="para2_img"><br>
<div id="para2" style="display:none">
This is my text for section 2!
</div>
<br>
<input type="image" src="https://casetest.blackboard.com/bbcswebdav/users/kas200/expand.gif" onclick="return toggleMe('para3')" value="Toggle" id="para3_img"><br>
<span id="para3" style="display:none">
This is my text for section 3!
</span>
here's a working example: http://jsfiddle.net/8h4T7/1/
PURE CSS
There's no need to use JS.
Here you go with a simple HTML / CSS solution:
LIVE DEMO
<input id="_1" class="toggler" type="checkbox">
<label for="_1"></label>
<div>This is my text for section 1!</div>
CSS:
.toggler,
.toggler + label + div{
display:none;
}
.toggler + label{
background: url(https://casetest.blackboard.com/bbcswebdav/users/kas200/expand.gif);
position:relative;
display:inline-block;
width:11px;
height:11px;
}
.toggler:checked + label{
background: url(https://casetest.blackboard.com/bbcswebdav/users/kas200/collapse.gif);
}
.toggler:checked + label + div{
display: block;
}
The good part is that both your images are loaded in the browser so there won't happen an useless image request to the server (creating a time-gap) with no image visible (while it's loading).
As you can see the trick is to hide the checkbox and the div,
than using the :checked state you can do your tricks.
PURE JS
If you really want to play with JS than here's some changes to simplify the HTML markup:
<input type="image" src="https://casetest.blackboard.com/bbcswebdav/users/kas200/expand.gif" value="para1"><br>
<div id="para1" style="display:none">This is my text for section 1!</div>
Note that I've changed the useless value to something useful, and removed the unnecessary ID from your inputs. Also, I've removed the messy HTML inline onclick callers. They're hard to maintain in production.
The input value will now help us to target your ID containers.
var imgSRC = "//casetest.blackboard.com/bbcswebdav/users/kas200/";
function toggleFn(){
var tog = this.tog = !this.tog;
var targetEl = document.getElementById(this.value);
targetEl.style.display = tog ? "block" : "none";
this.src = imgSRC + (tog?"collapse":"expand") + ".gif";
}
var $para = document.querySelectorAll("[value^=para]");
for(var i=0; i<$para.length; i++) $para[i].addEventListener('click', toggleFn, false);
LIVE DEMO 1
Another JS version:
var imgSRC = "//casetest.blackboard.com/bbcswebdav/users/kas200/";
function toggleFn(){
var el = document.getElementById(this.value);
el.style.display = el.style.display=='none' ? "block" : "none";
this.src = imgSRC +(this.src.match('expand') ? "collapse" : "expand")+ ".gif";
}
var $para = document.querySelectorAll("[value^=para]");
for(var i=0; i<$para.length; i++) $para[i].addEventListener('click', toggleFn, false);
LIVE DEMO 2
jQuery VERSION
Having the exact same as above HTML this is the needed jQuery code:
var imgSRC = "//casetest.blackboard.com/bbcswebdav/users/kas200/";
$(':image[value^="para"]').click(function(){
var tog = this.tog = !this.tog;
$('#'+ this.value).fadeToggle(); // or use .slideToggle();
this.src = imgSRC + (tog?"collapse":"expand") + ".gif";
});
LIVE DEMO
The interesting part of the code above is the way we store the current state directly into the this element reference Object:
var tog = thistog = !this.tog;
and using a set negation we create the toggle state.
Instead, if you're familiar with the bitwise XOR operator you can use it (to achieve the same) like:
var tog = this.t ^= 1;
XOR DEMO
Using jQuery
You can also use jQuery. It's a tool designed to help young coders. It allows manipulation of JavaScript through minimal functions.
Adding <script src="http://code.jquery.com/jquery-1.11.0.min.js"></script> to the head of your document will allow you to use jQuery. Then you can add some style to your collapsibles like this method based on pennstatephil's code.
function toggleMe(a){
var e=$('#'+a);
var i=$(a+'_img');
if(!e) return false;
if(e.css('display') == "none" ) {
i.attr('src', 'https://casetest.blackboard.com/bbcswebdav/users/kas200/collapse.gif');
e.fadeIn('slow');
}
else {
i.attr('src', 'https://casetest.blackboard.com/bbcswebdav/users/kas200/expand.gif');
e.fadeOut('fast');
}
return true;
}
And an example can be seen here
jQuery API Documentation can be found here
I wanna like that some plugin just one thing must be different there is have 2 links for 2 div i wanna show there example 10 div but with only one button like "Load More" how i can do this ?
html
Click1
Click2
<div id="outer">
<div id="inner">Initial content</div>
</div>
<div style="display:none" id="hidden1">After click event showing hidden 1</div>
<div style="display:none" id="hidden2">After click event showing hidden 2</div>
Js
$(document).ready(function() {
$('.link').click(function()
{
var id = $(this).attr('href');
$('#inner').fadeOut('slow', function() {
$('#inner').html($(id).html());
$('#inner').fadeIn('slow');
})
})
})
CSS
#hideMsg{
text-align:center;
padding-top:10px;
}
http://jsfiddle.net/G5qGs/2/
You can do it something like this.
Create a load more button
Load More
Use javascript like below
var count = 1;
$('#loadmore').click(function() {
$('#inner').fadeOut('slow', function() {
$('#inner').html($("#hidden" + count).html());
$('#inner').fadeIn('slow');
count++;
})
});
Working example
http://jsfiddle.net/G5qGs/25/
P.S : You might want to display "No more content" at the end. that can be achieved using a simple if else condition
I am trying to get the size of label text inside the div and chech of the size is 0 hide this div
Update the text is in dnn_ctr2802_View_lblHelp class dnnHelpText
javascript
$('.dnnTooltip').dnnTooltip();
//get the size of the hiden label
var labelTextSize = $(".dnnHelpText").val().length;
console.log("labelTextSize");
if(labelTextSize == 0)
{
$('.dnnTooltip').hide()
}
html
<div class="pull-right eyeball">
<img id="img_type" src="/ideaPark/DesktopModules/ExplorationTypeSaftyAlert/img/3.png" />
<img id="img_safety_alert" class="eyeball-warning" src="/ideaPark/DesktopModules/ExplorationTypeSaftyAlert/img/exploration-warning.png" />
</div>
<div class="dnnTooltip">
<label id="dnn_ctr2802_View_label">
<a id="dnn_ctr2802_View_cmdHelp" tabindex="-1" href="javascript:__doPostBack('dnn$ctr2802$View$cmdHelp','')"><span id="lblLabel"></span></a>
</label>
<div id="dnn_ctr2802_View_pnlHelp" class="dnnFormHelpContent dnnClear" style="display:none;">
<span id="dnn_ctr2802_View_lblHelp" class="dnnHelpText"> bnmbnmbnmbnmtfgjnfvyg</span>
</div>
try this & BTW try to use jquery UI function .remove()
var labelTextSize = $('.dnnHelpText').text().length;
console.log("text:" + labelTextSize.length);
if (labelTextSize == 1) {
$('.dnnTooltip').remove();
}
Try this:
var labelTextSize = $("#lblLabel").width();
And to test, try this:
console.log(labelTextSize);
UPDATE:
As anything worked I have search for other way to achieve this. I have found this question and maybe it works for you.
Try this:
$(".dnnHelpText").bind("DOMSubtreeModified", function(){
var labelTextSize = $(this).width();
if(labelTextSize == 0)
{
$('.dnnTooltip').hide()
}
});
That snipet add an event listener when the content of the label is been changed. So then, inside the event you may have access to it's properties to do your routine.
I am looking to hide a number of DIVs based upon the specific text of another DIV. My Javascript (below) isn't working.
The HTML:
<div id="LEGEND">abAB</div>
<div id="small-a"></div>
<div id="small-b"></div>
<div id="big-a"></div>
<div id="big-b"></div>
If the LEGEND DIV contains the text a, then I want it to show only DIV small-a.
If the LEGEND DIV contains the text bA, then I want it to show only DIV small-b and big-a.
The Javascript:
<script>
window.onload = function ShowHide{
if (document.getElementById('LEGEND').indexOf("a") > 0){
document.getElementById('small-a').style.display = 'block';}
if (document.getElementById('LEGEND').indexOf("b") > 0){
document.getElementById('small-b').style.display = 'block';}
if (document.getElementById('LEGEND').indexOf("A") > 0){
document.getElementById('big-a').style.display = 'block';}
if (document.getElementById('LEGEND').indexOf("a") > 0){
document.getElementById('big-b').style.display = 'block';}
</script>
You are forgetting a couple of things.
A function declaration should be like this
function functionName(args) {
}
You have to hide the divs using style.display = "none"
Example:
<div id="LEGEND">abB</div>
<div id="small-a" style="display: none;">This is small-a</div>
<div id="small-b" style="display: none;">This is small-b</div>
<div id="big-a" style="display: none;">This is big-a</div>
<div id="big-b" style="display: none;">This is big-b</div>
<script>
function showElement(id) {
document.getElementById(id).style.display = "block";
}
window.onload = function ShowHide() {
var legend = document.getElementById("LEGEND").innerHTML;
if(legend.indexOf("a") != -1) showElement("small-a");
if(legend.indexOf("b") != -1) showElement("small-b");
if(legend.indexOf("A") != -1) showElement("big-a");
if(legend.indexOf("B") != -1) showElement("big-b");
}
</script>
The problem is that your code changes the other div elements to block-level elements when div is already a block-level element. You need to set them not to display initially using CSS and then reveal them in the JavaScript.
Try this instead:
<div id="LEGEND">abAB</div>
<div id="small-a" style="display: none;"></div>
<div id="small-b" style="display: none;"></div>
<div id="big-a" style="display: none;"></div>
<div id="big-b" style="display: none;"></div>
<script type="text/javascript">
window.onload = function() {
if (document.getElementById('LEGEND').indexOf('a') > 0) {
document.getElementById('small-a').style.display = 'block';
...
// etc.
}
}
</script>
First, try making sure the window.onload is being called:
window.addEventListener('load', ShowHide, false);
function ShowHide()
{...
Second, you should be looking at the InnerHTML of the element:
if (document.getElementById('LEGEND').innerHTML.match("a") == "a"){...
Third, each if statement should also contain an else (replace divName with real div names):
else {
document.getElementById('divName').style.display = 'none'}
Hope that helps!
~md5sum~
EDIT:
Also, I'm not 100% sure on this, but I believe that the syntax:
window.onload = function ShowHide{
will completely fail. I think that the syntax should be:
window.onload = function(){
If me, I will do like this. you dont need to touch HTML part, everything is done in javascript.
you can extend it to CDEFGH...
and you don't need to set <div id="small-X" style="display: none;"> for each tags too. :-)
<body>
<script>
window.onload=function(){
x=document.getElementsByTagName("div");
//first hide everything with small- or big-
for(i in x)
if(/small-|big-/.test(x[i].id))
x[i].style.display="none";
//then turn on each tags based on LEGEND
x= document.getElementById("LEGEND").innerHTML;
for(i=0;i<x.length;i++)
document.getElementById((x[i]<='Z'?'big-':'small-')+x[i].toLowerCase()).style.display='block';
}
</script>
<div id="LEGEND">aAB</div>
<div id="small-a">a</div>
<div id="small-b">b</div>
<div id="big-a">A</div>
<div id="big-b">B</div>
</body>
You need to set the style.display property to none.
