For some reason the code below it is not working correctly. Unless I'm being quite stupid with my JavaScript I can't see what's going wrong besides the onclick events not firing on the <option>s.
function showOther() {
document.getElementById('other').value = "";
document.getElementById('other').style.display = 'block';
document.getElementById('otherBR').style.display = 'block';
}
function hideOther() {
document.getElementById('other').style.display = 'none';
document.getElementById('otherBR').style.display = 'none';
}
#other {
display: none;
}
#otherBr {
display: none;
}
<select name="" id="drop_down">
<option value="choose" onclick="hideOther();">Please choose</option>
<option value="Allure" onclick="hideOther();">Allure</option>
<option value="Elle" onclick="hideOther();">Elle</option>
<option value="In-Style" onclick="hideOther();">In-Style</option>
<option value="other" id="otherOption" onclick="showOther();">Other</option>
</select>
<input type="text" name="fields_where" id="other" placeholder="Other" />
<br id="otherBR" />
Add this function to your JS:
function showHideOther(){
if (document.getElementById('drop_down').value == 'other') {
showOther();
} else {
hideOther();
}
}
And change your select element like this:
<select name="" id="drop_down" onchange="showHideOther();">
<option value="choose">Please choose</option>
<option value="Allure">Allure</option>
<option value="Elle">Elle</option>
<option value="In-Style">In-Style</option>
<option value="other">Other</option>
</select>
function showHideOther() {
if (document.getElementById('drop_down').value == 'other') {
showOther();
} else {
hideOther();
}
}
function showOther() {
document.getElementById('other').value = "";
document.getElementById('other').style.display = 'block';
document.getElementById('otherBR').style.display = 'block';
}
function hideOther() {
document.getElementById('other').style.display = 'none';
document.getElementById('otherBR').style.display = 'none';
}
#other {
display: none;
}
#otherBr {
display: none;
}
<select name="" id="drop_down" onchange="showHideOther();">
<option value="choose">Please choose</option>
<option value="Allure">Allure</option>
<option value="Elle">Elle</option>
<option value="In-Style">In-Style</option>
<option value="other">Other</option>
</select>
<input type="text" name="fields_where" id="other" placeholder="Other" />
<br id="otherBR" />
An answer with JS only, not jQuery:
onclick event in option tag is just recognized by Firefox. If you need a solution that works on all browsers such as IE or Chrome you can use onchange event on your "Select" element.
HTML :
<select name="" id="drop_down" onchange="showHideOther(this.value);">
<option value="choose" ">Please choose</option>
<option value="Allure">Allure</option>
<option value="Elle" >Elle</option>
<option value="In-Style" >In-Style</option>
<option value="other" id="otherOption">Other</option>
</select>
JS defined in the html head section as script:
function showHideOther(value){
alert(value);
if (value==='other'){
document.getElementById('other').value = "";
document.getElementById('other').style.display = 'block';
document.getElementById('otherBR').style.display = 'block';
}
else{
document.getElementById('other').style.display = 'none';
document.getElementById('otherBR').style.display = 'none';
}
}
JSFiddle sample working fine: http://jsfiddle.net/amontellano/gLML3/14/
I hope it helps.
DEMO
var dropdown = document.getElementById('drop_down');
dropdown.onchange = function() {
var selected = dropdown.options[dropdown.selectedIndex].value;
switch(selected) {
case 'other':
document.getElementById('other').value = "";
document.getElementById('other').style.display = 'block';
document.getElementById('otherBR').style.display = 'block';
break;
default:
document.getElementById('other').style.display = 'none';
document.getElementById('otherBR').style.display = 'none';
break;
}
}
just add these function to your code:
$('#drop_down').on('change', function(){
($(this).val() == 'other') ? showOther() : hideOther();
});

I have this code, and when I click on story or career, I want it to get the h1, and also the div and display the paragraph or information for that link. So far it's only displaying the h1, and not the div or other information associated with that link.

> The problem is coming from here. It's not selecting the article with
the div.
$('section article').each(function () {
var isTrue = false;
$(this).children().each(function () {
var text = $(this).text().toLowerCase();
console.log(text);

You appear to be looking for the href in the article text but the href is the previous element to the article.
Does this fix the problem?
$('section article').each(function () {
var h1Link = $(this).prev().attr("id");
if(h1Link==href){
$(this).show();
}else{
$(this).hide();
}
});
I have a listbox, and I want to show a textarea if I have a selected item, it is so simple, but my code isn't working, can any one help me?
Listbox code :
<select onchange="change(this)" name="idUser" class="form-control">
<c:forEach items= '${listeU}' var='p' >
<option value="${p.getIdUser()}"> ${p.getIdUser()} - ${p.getNom()} ${p.getPrenom()}</option>
</c:forEach>
</select>
JS :
function change(obj) {
var selectBox = obj;
var selected = selectBox.options[selectBox.selectedIndex].value;
var textarea = document.getElementById("text_area");
if(selected === '1'){
textarea.show();
}
else{
textarea.style.display = "none";
}
}
Item to show :
<textarea id="text_area" type="text" name="text_area" style="display: none"></textarea>
show() is a jQuery and you're using pure JS so you should replace it by :
textarea.style.display = "block";
Hope this helps.
function change(obj) {
var selectBox = obj;
var selected = selectBox.options[selectBox.selectedIndex].value;
var textarea = document.getElementById("text_area");
if(selected === '1'){
textarea.style.display = "none";
}
else{
textarea.style.display = "block";
}
}
<select onchange="change(this)" name="idUser" class="form-control">
<option value="1"> option 1</option>
<option value="2"> option 2</option>
<option value="3"> option 3</option>
</select>
<textarea id="text_area" type="text" name="text_area" style="display: none"></textarea>
I am trying to display a div if user select a specific option value from a select drop down list.
Example:
The select drop down list consist of dynamic names fetched from the database and also one static or permanent name at the bottom of the list called "Admin"
If user select an option that's not "Admin", a div containing certain form element is shown else if the user select "Admin" that div remain hidden
Here is my code:
Javascript -
<script language="javascript">
function admSelectCheck(nameSelect)
{
if(nameSelect){
admOptionValue = document.getElementById("admOption").value;
if(admOptionValue != 0){
document.getElementById("admDivCheck").style.display = "";
}
else{
document.getElementById("admDivCheck").style.display = "none";
}
}
else{
document.getElementById("admDivCheck").style.display = "none";
}
}
</script>
HTML -
<select id="getFname" onchange="admSelectCheck(this.select);">
<option value="1">Jay</option>
<option value="4">Sam</option>
<option id="admOption" value="0">Admin</option>
</select>
<div id="admDivCheck" style="display:none;">
admin selected
</div>
Would be glad getting help with this.
Using this.select is incorrect.
Here is the correct code:
HTML
<select id="getFname" onchange="admSelectCheck(this);">
<option value="1">Jay</option>
<option value="4">Sam</option>
<option id="admOption" value="0">Admin</option>
</select>
<div id="admDivCheck" style="display:none;">
admin selected
</div>
JS
function admSelectCheck(nameSelect)
{
console.log(nameSelect);
if(nameSelect){
admOptionValue = document.getElementById("admOption").value;
if(admOptionValue == nameSelect.value){
document.getElementById("admDivCheck").style.display = "block";
}
else{
document.getElementById("admDivCheck").style.display = "none";
}
}
else{
document.getElementById("admDivCheck").style.display = "none";
}
}
See the demo on JSFiddle.
I think you need like this
Just Change this line:
JS
admOptionValue = document.getElementById("getFname").value;
//alert(admOptionValue);
if(admOptionValue == 0){
document.getElementById("admDivCheck").style.display = "";
}
else{
document.getElementById("admDivCheck").style.display = "none";
}
And also in HTML
onchange="admSelectCheck(this);"
see Demo
try this:
JS:
function admSelectCheck(nameSelect)
{
if(nameSelect){
admOptionValue = nameSelect.value;
if(admOptionValue != 0){
nameSelect.style.display = "";
}
else{
nameSelect.style.display = "none";
}
}
else{
nameSelect.style.display = "none";
}
}
HTML:
<select id="getFname" onchange="admSelectCheck(this);">
<option value="1">Jay</option>
<option value="4">Sam</option>
<option id="admOption" value="0">Admin</option>
</select>
<div id="admDivCheck" style="display:none;">
admin selected
</div>
Try
<select id="getFname" onchange="admSelectCheck(this);">
<option value="1">Jay</option>
<option value="4">Sam</option>
<option id="admOption" value="0">Admin</option>
</select>
<div id="admDivCheck" style="display:none;">
admin selected
</div>
And
function admSelectCheck(nameSelect)
{
var val = nameSelect.options[nameSelect.selectedIndex].value;
document.getElementById("admDivCheck").style.display = val == '0' ? "block" : 'none';
}
Demo: Fiddle
You can attach change event handler on body load event and hide/unhide <div> based on selection:
HTML
<select id="getFname">
<option value="1">Jay</option>
<option value="4">Sam</option>
<option id="admOption" value="0">Admin</option>
</select>
<div id="admDivCheck" style="display:none;">
admin selected
</div>
Put the following code in Head tag:
<script type="text/javascript">
function onload() {
document.getElementById("getFname").onchange = function (e) {
if (this.value == 0) {
document.getElementById("admDivCheck").style.display="";
} else {
document.getElementById("admDivCheck").style.display="none";
}
};
}
</script>
Call the onload function in body:
<body onload="onload()">
jsfiddle demo
Change this.select to this:
<select id="getFname" onchange="admSelectCheck(this);">
Then it should work okay. Also if you have jQuery you can simply do:
$("#getFname").change(function() {
var val = $(this).text();
if (val != "Admin") {
$("#div").show();
}
});
Will supply a pure JS function too.
<select id="getFname">
<option value="1">Jay</option>
<option value="4">Sam</option>
<option value="0">Admin</option>
</select>
<div id="admDivCheck" style="display:none;">
admin selected
</div>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.2.0/jquery.min.js"></script>
<script>
$("#getFname").on("change",function(){"0"===$(this).val()?$("#admDivCheck").show():$("#admDivCheck").hide()});
</script>

You can construct a new Element and append it to the DOM via Javascript. An example:
var newInput = document.createElement("input");
newInput.setAttribute("id", "newElement");
newInput.setAttribute("type", "text");
document.body.appendChild(newInput);
