Here is my script, what my goal is if other is selected in select, the other text input beside it will be enabled, this is what i've got so far, any approach will be really appreciated, I have 4 questions like this and I want it to be modular, best approach for doing my function to be reuseable.. How do I properly do this without any problem posting my data as 2 name inputs will generate 2 post variables in php.. T_T
<script type="text/javascript" charset="utf-8">
function validate()
{
var ddl = document.getElementById("cause_pain");
var selectedValue = ddl.options[ddl.selectedIndex].value;
if (selectedValue == "OTHER")
{
document.getElementsByClassName("causepain")[0].removeAttribute("name");
document.getElementsByClassName("causepain1")[0].removeAttribute("disabled");
}
}
</script>
<form action="test.php" method="GET">
<select class="select causepain" id="cause_pain" name="cause_pain" onchange="validate()">
<option value="" selected="selected">Select Cause of Pain</option>
<option value="ARTHRITIS">ARTHRITIS</option>
<option value="RHEUMATISM">RHEUMATISM</option>
<option value="OLD AGE">OLD AGE</option>
<option value="ACTIVE LIFESTYLE WHEN YOUNGER">ACTIVE LIFESTYLE WHEN YOUNGER</option>
<option value="OTHER">OTHER</option>
</select>
<input class="causepain1" type="text" id="cause_pain" name="cause_pain" size="40" onkeyup="clean('this.id')" disabled>
<input type="submit" id="submit"/>
</form>
This method is reusable and pretty straight forward. Using data attributes, you could specify the element that needs to be shown on the specific option element. Also before showing any input element hide the elements that were attributed to the previous selection.
Example:
<form action="test.php" method="GET">
<select class="select causepain" id="cause_pain" name="cause_pain">
<option value="" selected="selected">Select Cause of Pain</option>
<option value="ARTHRITIS">ARTHRITIS</option>
<option value="RHEUMATISM">RHEUMATISM</option>
<option value="OLD AGE">OLD AGE</option>
<option value="ACTIVE LIFESTYLE WHEN YOUNGER">ACTIVE LIFESTYLE WHEN YOUNGER</option>
<option value="OTHER" data-show="cause_pain_other">OTHER</option>
</select>
<input class="causepain1" type="text" id="cause_pain_other" name="cause_pain" size="40"
onkeyup="clean('this.id')" disabled style="display: none;">
<input type="submit" id="submit"/>
</form>
<script type="text/javascript" charset="utf-8">
var selectedOpt;
function selectionChanged(e) {
if (selectedOpt && selectedOpt.dataset.show) {
var showEl = document.getElementById(selectedOpt.dataset.show);
showEl.disabled = true;
showEl.style.display = 'none';
}
selectedOpt = this.querySelector('[value="'+e.target.value+'"]');
if (selectedOpt.dataset.show) {
var showEl = document.getElementById(selectedOpt.dataset.show);
showEl.disabled = false;
showEl.style.display = 'block';
}
}
document.querySelector('select').addEventListener('change', selectionChanged);
</script>
Your selectedOpt should be an object if you're using multiple selects on the same page and then just add the element to the object with the id as an index:
var selectedOpt = {};
...
selectedOpt[this.id] = this.querySelector('[value="'+e.target.value+'"]');

I have these conditional drop lists behaving on screen as expected, but I cannot get the selected values from the drop downs to output in the HTML form (I can if I don't include the javascript). Only the text inputs are outputing as per the xml result below (Company & Add1). I want the xml to contain the Location from the first drop down, and the selected city from the conditional 2nd drop down.

Do you want the value attribute or the text? Based on Get selected value in dropdown list using JavaScript? (similar to the first part), .value should work for the value attribute and .text for the text that is selected.
Also, please make two different questions instead of one question with 2 questions nested inside.
I make a script to calculate number.
But i want this script to be work only when user select dropdown to text2 (value=5)
But this script is not working (nothing happened when run the script) :(
Can anyone help or suggest me getting started with this script Please.
<select id="stt" onchange="copy()">
<option value="">Select</option>
<option value="8">text1</option>
<option value="5">text2</option>
<option value="4">text3</option>
</select><br>
Calculate<br>
<input type="text" id="input">
<input type="text" disabled="disabled" id="result">
<script>
function copy() {
if (document.getElementById("stt").value == "5") {
$(document).ready(function(){
$("#input").keyup(function(){
var val1 = +$("#input").val();
$("#result").val(val1*79);
});
});
}
}
</script>
**EDIT**: Changed $("#input").on("change" with $("#input").on("keypress".
New working JSFiddle: http://jsfiddle.net/L69dp/1/
HTML Code:
<select id="stt">
<option value="">
Select
</option>
<option value="8">
text1
</option>
<option value="5">
text2
</option>
<option value="4">
text3
</option>
</select><br>
Calculate<br>
<form>
<input id="input" type="text"> <input disabled="true" id="result" type=
"text">
</form>
JS Code:
$(function() {
function calculate() {
var sttval = $("#stt").val();
if (sttval == "5") {
var val1 = $("#input").val();
$("#result").val(val1 * 79);
} else {
$("#result").val("");
}
}
$("#stt").on("change", function() {
calculate();
});
$("#input").on("keypress", function() {
calculate();
});}());
You need to add a reference to the jquery library:
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js" ></script>
Put this before your existing script block.
Also, you do not need $(document).ready(function(){} inside the copy() function.
<head>
<script>
var value;
function copy() {
value=document.getElementById("stt").value; //get the value of select everytime it change the value
}
function dd()
{
if(value=="5")//if the value is 5 do the code below
{
var val1= document.getElementById('input');
document.getElementById('result').value=val1.value*79;
}
}
</script>
</head>
<body >
<select id="stt" onchange="copy()">
<option value="">Select</option>
<option value="8">text1</option>
<option value="5">text2</option>
<option value="4">text3</option>
</select><br>
<input type="text" id="input" oninput="dd()" >
<input type="text" disabled="disabled" id="result">

I have a drop html list. If I select an option from dropdown, I have to assign dropdown value to the javascript variable and display it on html
Here is my code
HTML:
<form method="post">
<select id="dropdown" name="dropdown" onchange="changeHiddenInput(this)">
<option value="1">One</option>
<option value="2">Two</option>
<option value="3">Three</option>
</select>
<input type="hidden" name="hiddenInput" id="hiddenInput" value="" />
<button onclick="changeHiddenInput (objDropDown)">Try it</button>
</form>
<div id="result"> </div>
Javascript:
function changeHiddenInput (objDropDown)
{
var objHidden = document.getElementById("hiddenInput");
objHidden.value = objDropDown.value;
var a = objHidden.value;
result.innerHTML = a || "";
}
But whenever I am submitting the values,it giving error. anything wrong here ?
DEMO
On your demo, you've selected the default onLoad option in jsfiddle.
This causes the site to wrap your entire code within a callback function, meaning that your showit function is not a global function as required by DOM0 inline event handlers.
Change this option to no wrap(head) and it will work.
The code you have will work good on a page, assuming you have the <script> tags for the javascript.
Fiddle here
About your <button onclick="changeHiddenInput (objDropDown)">Try it</button>, objDropDown is not defined... and also add type="button" otherwise the default is a submit button.
I made some changes for the demo, so my code is:
html
<form method="post">
<select id="dropdown" name="dropdown" onchange="changeHiddenInput(this)">
<option value="1">One</option>
<option value="2">Two</option>
<option value="3">Three</option>
</select>
<input type="hidden" name="hiddenInput" id="hiddenInput" value="" />
<button onclick="changeHiddenInput (objDropDown)">Try it</button>
</form>
<div id="result"> </div>
javascript
var select;
window.onload = function () {
select = document.getElementById('dropdown');
console.log(select);
}
function changeHiddenInput(objDropDown) {
console.log(objDropDown);
var objHidden = document.getElementById("hiddenInput");
objHidden.value = objDropDown.value;
var a = objHidden.value;
result.innerHTML = a || "";
}
I have a drop down menu, with two options:
<select name="chs" value="" id = ""/>
<option value="">ICE Cream</option>
<option value="">Juice</option>
</select>
This is what I want to have: in the first page you see a select, with two option, if you choose ICE cream another select will appear with different flavors (chocolate, vanilla, etc), and the same for juice.
This is what I already have:
html:
<label>Choose Skin</label><br /><select name="na" value="" id = ""/>
<option value="">ICE Cream</option>
<option value="">Juice</option>
</select>
<select name="icecreamfla" value="" onchange="showSelect()" id = "framework"/>
<option id="jm">vanilla</option>
<option id = "wp">chocholate</option>
</select>
<input type="submit" name = "redirect" value="go" />
The JavaScript:
function showSelect()
{
var select = document.getElementById('skin');
if(select.value == "juice"){
alert('saeed khare!');
}
else{
var option = document.getElementById('icecreamfla');
option.style.display = 'inline';
}
}
option.style.display used to be 'none', then I changed it to inline.
if any one can help please do it.
Here is a small demo with the flavours <select> only appearing when Ice Cream is selected.
It should be easy to follow to implement this to display a different <select> if the user chooses Juice.
Edit: If you want the selected value you can use types.options[types.selectedIndex].text to get it using the variables in my demo.
Is this you want to do it .
<script language='javascript'>
function showSelect()
{
var select = document.getElementById('skin').value;
if(select == "ICE Cream"){
var str="<select name='icecreamfla' value='' id = 'icecreamfla'/>"
+"<option id='jm'>vanilla</option>"+
"<option id ='wp'>chocholate</option> </select>";
document.getElementById("flavour").innerHTML=str;
}
}
<label>Choose Skin</label><br /><select name="na" value="" id = "skin" onchange="showSelect()">
<option value="ICE Cream">ICE Cream</option>
<option value="Juice">Juice</option>
</select>
<div id="flavour"></div>
<input type="submit" name = "redirect" value="go" />
I can't seem to get this function to work out. I'm trying to change the "business" input value of my form based on an amount selected in the "amount" dropdown. What am I missing!!! I've been trying this for an hour.
<script type="text/javascript">
function chPy()
{
var businessvar = "paypals#ramatico.com";
if (document.forms['5'].amount.value > 11){
businessvar = "paypall#ramatico.com"
}
document.forms['5'].business.value = businessvar;
}
</script>
<form name="5">
<select name="amount" OnChange="chPy()">
<option value="na">Select</option>
<option value="1.00">$1</option>
<option value="5.00">$5</option>
<option value="10.00">$10</option>
<option value="15.00">$15</option>
<option value="20.00">$20</option>
<option value="25.00">$25</option>
</select>
<input name="business" type="text" value="">
</form>
Ok. The next step. I have about 100 of these forms on a page. Instead of creating one for each form, I'd like to have one script that changes based on which form is being changed with "onChange". Each of the forms on the page have values of the same name (but not ID) (they are for paypal). I think it will be ok if I can change the"formname" in the following: "document.forms['formname']" based on a variable populated by something like chPy("formname") etc..... I can't seem to get that to work either.
Removing the form reference would take care of both of your items.
<script type="text/javascript">
function chPy(oSelect)
{
var businessvar = "paypals#ramatico.com";
if (oSelect.form.amount.value > 11){
businessvar = "paypall#ramatico.com"
}
oSelect.form.business.value = businessvar;
}
</script>
<form name="5">
<select name="amount" OnChange="chPy(this)">
<option value="na">Select</option>
<option value="1.00">$1</option>
<option value="5.00">$5</option>
<option value="10.00">$10</option>
<option value="15.00">$15</option>
<option value="20.00">$20</option>
<option value="25.00">$25</option>
</select>
<input name="business" type="text" value="">
</form>
Problem is that you are using a number as form name.
Add some letters to the name and it will work:
<script type="text/javascript">
function chPy()
{
var businessvar = "paypals#XYZ.com";
if (document.forms['form5'].amount.value > 11){
businessvar = "paypall#XYZ.com"
}
document.forms['form5'].business.value = businessvar;
}
</script>
<form name="form5">
<select name="amount" OnChange="chPy()">
<option value="na">Select</option>
<option value="1.00">$1</option>
<option value="5.00">$5</option>
<option value="10.00">$10</option>
<option value="15.00">$15</option>
<option value="20.00">$20</option>
<option value="25.00">$25</option>
</select>
<input name="business" type="text" value="">
</form>
HTML:
<form name="form5">
<select name="amount">
<option value="na">Select</option>
<option value="1.00">$1</option>
<option value="5.00">$5</option>
<option value="10.00">$10</option>
<option value="15.00">$15</option>
<option value="20.00">$20</option>
<option value="25.00">$25</option>
</select>
<input type="text" name="business">
</form>
JavaScript:
var form5 = document.forms['form5'];
form5.amount.onchange = function() {
form5.business.value =
(this.value > 11 ? 'paypall' : 'paypals') + '#ramatico.com';
}
Live demo: http://jsfiddle.net/Fx7zh/
For multiple forms, you can use this JavaScript code:
for (var i = 0, l = document.forms.length; i < l; i++) {
document.forms[i].amount.onchange = function(i) {
this.form.business.value =
(this.value > 11 ? 'paypall' : 'paypals') + '#ramatico.com';
}
}
