I've been trying to get this to work and thought it would be relatively easy but i'm just unable to target my div's with javascript.
I want a list of boxes and each one will be clickable and each one has a buddy which is hidden. when you click a , it hides and shows its buddy which will have an input box. Type the text in you need and press ok and it changes back to it's original displaying the text you have entered.
the head contains the following:
<head>
<script language="javascript">
var state = 'none';
function showhide(layer_ref) {
if (state == 'block') {
state = 'none';
}
else {
state = 'block';
}
if (document.all) { //IS IE 4 or 5 (or 6 beta)
eval( "document.all." + layer_ref + ".style.display = state");
}
if (document.layers) { //IS NETSCAPE 4 or below
document.layers[layer_ref].display = state;
}
if (document.getElementById &&!document.all) {
hza = document.getElementById(layer_ref);
hza.style.display = state;
}
}
</script>
And then my HTML contains:
<div id="div0">
<a href="#" onclick="showhide('div1');" style="text-decoration:none;">
<div style="width:200px; height:30px; background-color:grey;color:white">
Input: <div id="showinput"></div>
</div>
</a>
</div>
<div id="div1" style="display:none;">
<div style="width:200px; height:30px; background-color:grey;color:white">
<input type="text id="addInput" /">
<input type="submit" value="submit" name="submit" onclick="showhide('div1');" />
</div>
</div>
I'm trying to add the following but it just won't update the original and the script just makes the buddy div show below the original. How can i hide the original at the same time?
var myobj = document.getElementById("addInput");
var mytext = myobj.value;
document.getElementById("showinput").innerHTML = mytext;
You are missing a closing quote around type="text so the input id is not set. Try:
<input type="text" id="addInput" />

I am creating new rows using jquery and want to delete that row when delete button is pressed. Adding new row part is working fine and the problem is in delete part. When I click on delete button then nothing happens. It doesn't even show alert which is written in code. It seems to me like delete button is not even getting pressed.
How can I delete that particular record when delete button is pressed?
JSfiddle is given below
https://jsfiddle.net/ec2drjLo/
<div class="row">
<div>
Currency: <input type="text" id="currencyMain">
</div>
<div>
Amount: <input type="text" id="amountMain">
</div>
<div>
<button id="addAccount">Add Account</button>
</div>
</div>
<div id="transactionRow">
</div>
As you have added the elements as a string, they are not valid HTML elements and that's why you can't add an event listener. You can add the click event to the document body and capture the event target, like
$(document).on('click', function (e){
if(e.target.className === 'deleteClass'){
//process next steps
}
}
You can try the demo below, not sure if it's the result you need, but the delete button works. Hope it helps!
let accountCount = 0;
$("#addAccount").click(function (e)
{
accountCount++;
let mystring = "<label class=\"ok\" id=\"[ID]\">[value]</label>";
let deleteString = "<button class=\"deleteClass\" id=\"deleteAccount"+ accountCount +"\">Delete Account</button>";
let currency = mystring.replace("[ID]", "currency"+ accountCount).replace("[value]", $("#currencyMain").val());
let amount = mystring.replace("[ID]", "amount"+ accountCount).replace("[value]", $("#amountMain").val());
$("#transactionRow").append(currency);
$("#transactionRow").append(amount);
let div = document.createElement('div');
div.innerHTML =deleteString;
$("#transactionRow").append(div);
$("#currencyMain").val('');
$("#amountMain").val('')
});
$(document).on('click', function (e)
{
if(e.target.className === 'deleteClass'){
var content = $("#transactionRow").html();
var pos = content.lastIndexOf("<label class=\"ok");
if(pos > 5)
$("#transactionRow").html(content.substring(0,pos));
else
alert("You cannot delete this row as at least one Account must be present");
}
});

I have written code that creates a checkbox list where when i click the checkbox below my list of options i would like a link to show underneath that the user can click (show/hide) I cannot figure out why my code will not work. If the user unchecked the box the link disappears but nothing happens when i click my check boxes. I would like to do this fix in JQuery
<!DOCTYPE html>
<html>
<div class ="container">
<head></head>
<body>
<input id="grp1" type="checkbox" value="group_1" onClick="http://google.com" />
<label for="grp1"> group 1 </label>
<div>
<input id="grp2" type="checkbox" value="group_2" onClick="http://google.com" >
group_2</label>
</div>
</body>
</html>
You'll have to use javascript to hide/show the wanted elements in html. There are many approaches to this. The most basic one would be something like
<!DOCTYPE html>
<html>
<body>
<div id="container">
<input id="grp1" type="checkbox" value="group_1"/>
<label for="grp1"> group 1 </label>
<br>
<input id="grp2" type="checkbox" value="group_2"/>
<label for="grp2"> group_2</label>
<!--hidden elements using css-->
Link for group_1
<br>
Link for group_2
</div>
<script>
//listen to the click event on the whole container
document.getElementById("container").onclick = function (e) {
//check every box if it's checked
if (document.getElementById('grp1').checked) {
document.getElementById('url1').style.display = 'block';
} else {
document.getElementById('url1').style.display = 'none';
}
if (document.getElementById('grp2').checked) {
document.getElementById('url2').style.display = 'block';
} else {
document.getElementById('url2').style.display = 'none';
}
}
</script>
</body>
</html>
Of course you can use different approaches like creating the element in javascript then adding it to the html if you don't like the idea if existing hidden elements. You might also use loops to loop through checkbox element and simply show/hide the url accordingly. And more to make the code flexible on any number of boxes. Something like this
<!DOCTYPE html>
<html>
<body>
<div id="container">
<div id="checkBoxContainer">
<input id="grp1" type="checkbox" value="group_1"/>
<label for="grp1"> group 1 </label>
<br>
<input id="grp2" type="checkbox" value="group_2"/>
<label for="grp2"> group_2</label>
</div>
<!--hidden elements using css-->
Link for group_1
<br>
Link for group_2
</div>
<script>
//listen to the click event on the whole container
document.getElementById("checkBoxContainer").onclick = function (e) {
var linkNumber = 1; //This is number of the first url element with ud url1
var containerChildren = document.getElementById("checkBoxContainer").children;
//loop through the children elements
for (var i = 0; i < containerChildren.length; i++) {
var oneChild = containerChildren[i]; //catch only one child in a variable
//simply filter the input elements which are of type checkbox
if(oneChild.tagName === "INPUT" && oneChild.type === "checkbox"){
//Show or hide the url accordingly.
if (oneChild.checked) {
document.getElementById('url' + linkNumber++).style.display = 'block';
} else {
document.getElementById('url' + linkNumber++).style.display = 'none';
}
}
}
}
</script>
</body>
</html>
The onclick HTML attribute doesn't work that way. The attribute value is executed as javascript. You can make a js function to show/hide the link.
Hi you want to try this:
<!DOCTYPE html>
<html>
<head>
<style type="text/css">
.group-link{
display: block;
}
.hidden{
display: none;
}
</style>
</head>
<body>
<div class="jsParent">
<label for="grp1">
<input id="grp1" type="checkbox" value="group_1" onchange="showLink(this)"/> group 1
</label>
<a class="group-link hidden jsLink" href="https://www.animalplanet.com/tv-shows/dogs-101/videos/the-doberman">Group 1 Link</a>
</div>
<div class="jsParent">
<label for="grp2">
<input id="grp2" type="checkbox" value="group_2" onchange="showLink(this)"/> group_2
</label>
<a class="group-link hidden jsLink" href="https://www.animalplanet.com/tv-shows/cats-101/videos/ragdoll">Group 2Link </a>
</div>
<script type="text/javascript">
function showLink(el){
var parent = el.parentElement.parentElement;
var linkEl = getAnchorEl(parent);
if(linkEl){
if(el.checked){
linkEl.classList = linkEl.classList.value.replace('hidden', '');
}else{
linkEl.classList = linkEl.classList.value + ' hidden';
}
}
}
function getAnchorEl(parent){
var childrens = parent.children;
var linkEl = null;
for (var i = 0; i < childrens.length; i++) {
var childEl = childrens[i];
if(childEl.classList.value.indexOf('jsLink') > -1){
linkEl = childEl;
break;
}
}
return linkEl;
}
</script>
</body>
</html>
Your question is undoubtedly a duplicate but I am answering because I would like to help you identify issues with the code you posted.
I notice you have a <div>tag between your tag and tag. Why? This is a bit of an over simplification but as a general rule never put anything between your <html> and <head> tag and only place <div> tags inside your <body> tag. Also be mindful of how you nest your elements. That tag starts after and before .
Even if that were correct placement you close the before you close your div arbitrarily in the middle of your body tag. you should never have
<div>
<p>
</div>
</p>
Instead it should look like this
<div>
<p>
</p>
</div>
In your onClick attribute you have a random URL. That will not open a new window. You new too put some javascript in there.
<input onClick="window.open('http://google.com')">
Also your second label tag does not have an opening, just a </label> close tag
To answer your question - I suggest you look at the jQuery toggle function.
<input type="checkbox" id="displayLink" />
Google
<script type="text/javascript">
$("#displayLink").click(function(){
$("#googleLink").toggle();
});
</script>
As a general rule you should favor event handlers (such as the $("").click() posted above) to handle events (like clicking) as opposed to html attributes such as onClick.
I'm building an about us page and I'm hoping to use JavaScript to show/hide/replace a DIV's content with a vision statement or a bio depending on which is clicked by the user. I'm brand new to using script, so I'm hoping there is someone who has done this before.
I currently have a button for the bio and one for the vision and while I'm able to show and hide text with no problem I have no clue how to replace the DIV so that the Bio and Vision don't show at the same time.
Here is what I have so far:
function showhide(id) {
var e = document.getElementById(id);
e.style.display = (e.style.display == 'block') ? 'none' : 'block';
}
<button type="button" onclick="javascript:showhide('vision')">Vision</button>
<button type="button" onclick="javascript:showhide('bio')">Bio</button>
<div id="vision" style="display: none;">
<p>This is my vision</p>
</div>
<div id="bio" style="display: none;">
<p>This is my bio</p>
</div>
I'd also like the button text to change to "Hide Bio" or "Hide Vision" depending on which is revealed as well.
If anyone could help with this it would be GREATLY appreciated for a Java Noob like me.
This is also my first time using a forum like this so any pointers or feedback is appreciated...gotta start somewhere, right?
UPDATE - I attached an image to give a better idea of what I'm try to accomplish.
There are a couple of issues with logic. If you show/hide one div, you'll still need to hide/show the second div. So you can either add more lines of code to do that.. or simply you can use one div and update its content based on the button clicked.
so you can try this:
<script>
var textStrings = {"author1": {"Vision":"this is author1 vision", "Bio":"this is author1 bio"},
"author2": {"Vision":"this is author2 vision", "Bio":"this is author2 bio"},
"author3": {"Vision":"this is author3 vision", "Bio":"this is author3 bio"}};
function showhide(element) {
reset();
var id=element.id;
var author = document.getElementById("authors").elements["authors"].value;
var flag = document.getElementById('content').innerHTML == textStrings[author][id];
document.getElementById('content').innerHTML = flag ? "" : textStrings[author][id];
element.innerHTML = flag ? id : "hide " + id;
}
function reset(){
for (var k in textStrings["author1"]){
document.getElementById(k).innerHTML = k;
}
}
function resetAuthor(){
document.getElementById('content').innerHTML = ""
reset();
}
</script>
<form id="authors">
<input type="radio" name="authors" id="author1" onchange="resetAuthor()" value="author1" checked> author 1
<input type="radio" name="authors" id="author2" onchange="resetAuthor()" value="author2"> author 2
<input type="radio" name="authors" id="author3" onchange="resetAuthor()" value="author3"> author 3
</form>
<div style="display:inline">
<button type="button" id="Vision" onclick="javascript:showhide(this)">Vision</button>
<button type="button" id="Bio" onclick="javascript:showhide(this)">Bio</button>
</div>
<div style="display: block;">
<p id="content"></p>
</div>
This code also toggles/set contents as empty if you hit the button again.
DEMO
Try to pass the this object into the inline event handler and check the content's display state to toggle the button's text,
HTML:
<button type="button" onclick="javascript:showhide('vision',this)">Vision</button>
<button type="button" onclick="javascript:showhide('bio',this)">Bio</button>
<div id="vision" style="display: none;">
<p>This is my vision</p>
</div>
<div id="bio" style="display: none;">
<p>This is my bio</p>
</div>
JS
function showhide(id,elem) {
var e = document.getElementById(id);
var cond = (e.style.display == 'block');
e.style.display = cond ? 'none' : 'block';
elem.textContent = (id == "vision") ? (cond ? "Show Vision" : "Hide Vision")
: (cond ? "Show Bio" : "Hide Bio");
}
DEMO
Try this out.
var prevPage = "";
var currPage = "";
function showhide(event) {
prevPage = currPage;
currPage = event.id.split("_")[1];
if(prevPage !== currPage){
showEle(currPage);
if(prevPage !== ''){
hideEle(prevPage);
}
} else {
toggle(currPage);
}
}
function toggle(id){
var curr = document.getElementById(id);
if(curr.style.display === 'block'){
curr.style.display = 'none';
updateBtn('btn_'+id, 'Show');
} else {
curr.style.display = 'block';
updateBtn('btn_'+id, 'Hide');
}
}
function updateBtn(id, newStr){
var btn = document.getElementById(id);
btn.innerHTML = newStr + ' ' + btn.innerHTML.split(' ')[1];
}
function showEle(id){
document.getElementById(id).style.display = 'block';
updateBtn('btn_'+id, 'Hide');
}
function hideEle(id){
document.getElementById(id).style.display = 'none';
updateBtn('btn_'+id, 'Show');
}
<button id="btn_vision" type="button" onclick="showhide(this)">Show Vision</button>
<button id="btn_bio" type="button" onclick="showhide(this)">Show Bio</button>
<button id="btn_xyz" type="button" onclick="showhide(this)">Show Xyz</button>
<button id="btn_abc" type="button" onclick="showhide(this)">Show Abc</button>
<div id="vision" style="display: none;">
<p>This is my vision</p>
</div>
<div id="bio" style="display: none;">
<p>This is my bio</p>
</div>
<div id="xyz" style="display: none;">
<p>This is my xyz</p>
</div>
<div id="abc" style="display: none;">
<p>This is my abc</p>
</div>
Note: You might want to initialize the currPage with the first page's id since it gives a better feel.
Say currPage = "vision" and also make display block for div id = "vision".
I want to configure a hyperlink to close/open its related div in asp.net. Basically, when a user clicks the sign X, the panel should be closed and the sign + should be appeared. When + is clicked, the panel should be showed again. I could not manage this and I believe my main problem is "document.getElementById('<%= lb_closePanel.ClientID %>').value" is coming as undefined. Here is the code until now. I appreciate for your helps!
<!DOCTYPE html>
....
<div class="appheader">
<h1 class="appheaderContent">Search for Client</h1>
<div id="checkBox"></div>
<div id="closePanel"><h2 id="lblClosePanel">Close Panel</h2>
<div id="xButton">
<asp:LinkButton onclientclick="CloseOpenPanel('Search')" runat="server" Text="X" style="text-decoration:none; color:white" ID="lb_closePanel"></asp:LinkButton>
</div>
</div>
</div>
<div class="app" id="Search">
...
<div>
...
</html>
<script type="text/javascript">
function CloseOpenPanel(obj) {
alert(document.getElementById('<%= lb_closePanel.ClientID %>').value); //here it comes undefined!!!!
if (document.getElementById('<%= lb_closePanel.ClientID %>').value == 'X') {
document.getElementById(obj).Visible = false;
lb_closePanel.Text = '+';
}
else {
document.getElementById(obj).Visible = true;
lb_closePanel.Text = 'X';
}
}
</script>
Your code is OK, just instead of the property value use innerHTML
alert(document.getElementById('<%= lb_closePanel.ClientID %>').innerHTML);
Instead of using .value, try using .innerHTML instead to get the text inside of your link button (rendered as an a tag)
I am trying to hide the div's when different buttons are clicked but I don't know how to. (So when 'Test 1' is clicked it should hide 'Test 2' Div and vice versa) I checked here and on Google but couldn't find an answer for it.
Javascript :
function showHide(divId) {
var theDiv = document.getElementById(divId);
if (theDiv.style.display == "none") {
theDiv.style.display = "";
} else {
theDiv.style.display = "none";
}
}
HTML :
<input type="button" onclick="showHide('hidethis')" value="Test It">
<div id="hidethis" style="display:none">
<h1>TEST ME!</h1>>
</div>
<input type="button" onclick="showHide('hidethis2')" value="Test It 2">
<div id="hidethis2" style="display:none">
<h1>TEST MEEEEEEEEEEEEEEE 2!</h1>
</div>
JSFIDDLE: is not doing it here but works locallyhttp://jsfiddle.net/S5JzK/
<input type="button" onclick="showHide('hidethis')" value="Test It" />
<div id="hidethis" style="display:none">
<h1>TEST ME!</h1>
</div>
<input type="button" onclick="showHide('hidethis2')" value="Test It 2">
<div id="hidethis2" style="display:none">
<h1>TEST MEEEEEEEEEEEEEEE 2!</h1>
</div>
function showHide(divId) {
$("#"+divId).toggle();
}
Check the Fiddle http://jsfiddle.net/S5JzK/7/
Please try this, it works well and so simple,
<html>
<head>
<style>
.manageDiv{
display:none;
}
</style>
</head>
<body>
<input type="button" class="testButton" value="Test It" />
<input type="button" class="testButton" value="Test It 2" />
<div id="hidethis2" class="manageDiv">
<h1>TEST MEEEEEEEEEEEEEEE 2!</h1>
</div>
</body>
</html>
$(function(){
$(".testButton").on("click", function(){
$("#hidethis2").toggleClass("manageDiv");
});
});
To it work in fiddle, in your example, you need to select (No wrap - in head) on the left.
Look the example below, using pure javascript:
HTML
<input type="button" onclick="showHide('hidethis')" value="Test It">
<div id="hidethis" style="display:none">
<h1>TEST ME!</h1>
</div>
<input type="button" onclick="showHide('hidethis2')" value="Test It 2">
<div id="hidethis2" style="display:none">
<h1>TEST MEEEEEEEEEEEEEEE 2!</h1>
</div>
JAVASCRIPT
function showHide(divId) {
/* Hide all divs */
var elements = document.getElementsByTagName('div');
for (var i = 0; i < elements.length; i++) {
elements[i].style.display = "none";
}
/* Set display */
var theDiv = document.getElementById(divId);
theDiv.style.display = "";
}
http://jsfiddle.net/S5JzK/9/
ANOTHER JAVASCRIPT EXAMPLE
function showHide(divId) {
/* Hide the divs that you want */
var div1 = document.getElementById('#hidethis');
var div2 = document.getElementById('#hidethis2');
div1.style.display = "none";
div2.style.display = "none";
/* Set display */
var theDiv = document.getElementById(divId);
theDiv.style.display = "";
}
Using JQuery:
function showHideDiv(divId, bShow) {
if (bShow) {
$("#" + divId).show();
} else {
$("#" + divId).hide();
}
}
your code seems fine. are you sure you enter the function upon click? try adding a breakpoint using developer tools or an alert.
Anyways, I see you tagged this post with jquery. you can you it to do the task more elegantly.
$("#" + theDiv).hide();
or for showing it:
$("#" + theDiv).show();
"JSFIDDLE: is not doing it here but works locally"
Yes, because by default jsfiddle wraps your JS in an onload handler, which means the function declaration is local to that handler. Inline html attribute event handlers like your onclick="showHide('hidethis')" can only call global functions.
Under jsfiddle's Frameworks & Extensions heading there's a drop-down where you can change the default "onload" to "No wrap - in head" (or "No wrap - in body"). That'll make your function declaration global as in your local implementation.
