In my registration page, I'm gonna use two drop-down select that one of them should be hidden if its Negative and if its positive new drop-down will open to choose ...
In mysql table I've table as diabetes name with enom
enum('negative', 'insulin', 'drug', 'ndm', 'mody', '')
Here's my code:
<div><label for="diabetes">Diabetes:</label>
<select id="diabetes" name="diabetes">
<option value="negative">Negative</option>
<option value="">Positive</option>
</select>
</div>
<div><label for="diabetestype">Diabetes Type:</label>
<select id="diabetestype" name="diabetestype">
<option value="insulin">Insulin</option>
<option value="drug">Drug</option>
<option value="ndm">NDM</option>
<option value="mody">MODY</option>
</select>
</div>
For example: If Diabetes is negative value is negative as default then Diabetes Type is hidden
and
If Diabetes is positive then Diabetes type will be appeared to choose items.
those values like insulin, drug, mdm, mody should be inserted into this:
value="positive"
How can I make it through java script?
I can't add class or div or span. Is it possible just through JavaScript using ??
Thank you so much
Use jquery, it is comparatively easier.
$(document).ready(function(){
$("#diabetestype").hide();
$("#diabetes").on("change", function(){
var v = $(this).val();
if(v=="positive"){
$("#diabetestype").show();
}else{
$("#diabetestype").hide();
}
});
});
To make this code workable, you need to add value of Positive option also. So instead value="" change it to value="positive".
You can even hide the label also:
$(document).ready(function(){
$("#diabetestype").closest("div").hide();
$("#diabetes").on("change", function(){
var v = $(this).val();
if(v=="positive"){
$("#diabetestype").closest("div").show();
}else{
$("#diabetestype").closest("div").hide();
}
});
});
<div><label for="diabetes">Diabetes:</label>
<select id="diabet" name="diabet" onchange="checkDiabet();">
<option value="negative">Negative</option>
<option value="positive" id="isDiabet">Positive</option>
</select>
</div>
<div id="type" style="display: hidden;">
<label for="diabetestype">Diabetes Type:</label>
<select id="diabetestype" name="diabetestype">
<option value="insulin">Insulin</option>
<option value="drug">Drug</option>
<option value="ndm">NDM</option>
<option value="mody">MODY</option>
</select>
</div>
<script>
function checkDiabet() {
var isDiabet = document.getElementById("isDiabet").selected;
if (isDiabet == true) { document.getElementById("type").removeAttribute("style"); }
else { document.getElementById("type").style.display = "none"; }
}
</script>
First, set the first select to fire the function checkDiabet() by the attribute onchange. Then give the option an id, which needs to be checked, so you can access it easily.
Then, set the second select to display: none This could be done in a CSS header or file, or like in this case inline. (div style=""), also add an id to access it easily. (div id="type")
Now comes the function checkDiabete(). It checks if the select is selected (can be true or false (bool)). Is selected => show (div id="type"), if not, hide this div (and all of it's contents)
(if is already hidden, it then overwrites the (style="display: none;") with (style="display: none;))
That's it! :)
Try this:
function SelectDiabetes() {
var d = document.getElementById("diabetes").value;
var dType = document.getElementById("diabetestypebox");
if(d == "negative")
dType.style.display = "none";
else
dType.style.display = "block";
}
SelectDiabetes();
<div><label for="diabetes">Diabetes:</label>
<select id="diabetes" name="diabetes" onchange="SelectDiabetes(this.value);">
<option value="negative">Negative</option>
<option value="positive">Positive</option>
</select>
</div>
<div id="diabetestypebox"><label for="diabetestype">Diabetes Type:</label>
<select id="diabetestype" name="diabetestype">
<option value="insulin">Insulin</option>
<option value="drug">Drug</option>
<option value="ndm">NDM</option>
<option value="mody">MODY</option>
</select>
</div>
Call a js function onchange of select id diabetes
<div><label for="diabetes">Diabetes:</label>
<select id="diabetes" name="diabetes" onchange="toggleTypes()">
<option value="negative">Negative</option>
<option value="">Positive</option>
</select>
</div>
<div><label for="diabetestype">Diabetes Type:</label>
<select id="diabetestype" style="display:none" name="diabetestype">
<option value="insulin">Insulin</option>
<option value="drug">Drug</option>
<option value="ndm">NDM</option>
<option value="mody">MODY</option>
</select>
</div>
Use the following javascript
function toggleTypes(){
var el=document.getElementById('diabetes');
var medElem=document.getElementById('diabetestype');
if(el.value=='positive') {
medElem.style.display='block';
} else {
medElem.style.display='none';
}
}

I am doing to change 2nd select tag name by javascript.
this is my HTML
1st select
<select name="bank" id="bank" class="select" onchange="myFunction(event)">
<option value="Bank Account" a="required">Bank Account</option>
<option value="UPI" a="hidden">UPI</option>
</select>
2nd Select
<select name="bank1" class="select" id="bank1" required>
<option disabled selected>Choose Bank Name</option>
<option value="SBI">SBI</option>
<option value="PNB" >PNB</option>
</select>
this is my javascript
function myFunction(e) {
document.getElementById("bank1").name = e.target.a
but i want to change in 2nd select required to hidden
probably you are looking for setAttribute.
document.getElementById("bank1").required = false;
And for style mutation. As #Kokodoko had already written.
document.getElementById("bank1").classList.add("hidden")
Do you want to hide the second select box completely?
function myFunction(e) {
document.getElementById("bank1").classList.add("hidden")
}
CSS
#bank1.hidden {
display:none;
}
I am trying to send a value to an based on a selection from a dropdown list such as . I want to fetch the value of possiblePhone.id and send it to .
<script>
function copyTextValue() {
var text1 = document.getElementById("source").value;
document.getElementById("destination").value = text1;
}
</script>
<div>
<select th:field="${possiblePhones}">
<option value="0">select phone</option>
<option id="source" onselect="copyTextValue()"
th:each="possiblePhone : ${possiblePhones}"
th:value="${possiblePhone.id}"
th:text="${possiblePhone.model}"></option>
</select>
</div>
<td><input type="text" id="destination"> </td>
For example, if "Samsung" is selected then "1" should be send to the input field and so on. Actually, i do not get any output.
<select id="source" onchange="copyTextValue()">
<option value="0">select phone</option>
<option value="1">samsung</option>
<option value="2">something</option>
</select>
The id="source" attribute should be in <select> element, also change onselect to onchange and move it to <select> element too.
Codepen: https://codepen.io/anon/pen/WVxLpz
You can achieve this by setting the listener to the select element and then query the selected option value.
I made a minimal example with two brands:
<script>
function copyTextValue() {
var e = document.getElementById("select");
var val = e.options[e.selectedIndex].value;
document.getElementById("destination").value = val;
}
</script>
<div>
<select onchange="copyTextValue()" id="select">
<option value="0">select phone</option>
<option value="1">Brand 1</option>
<option value="2">Brand 2</option>
</select>
</div>
<td><input type="text" id="destination"> </td>
one of the simple thing you have to observe here is that you have to capture the event when the dropdown is selected, and pass the current dropdown reference to your method.
<script>
function copyTextValue(selectedOption) {
if(selectedOption.selectedIndex <= 0){
document.getElementById("destination").value = '';
return;
}
var selectedOptionValue = selectedOption.value;
document.getElementById("destination").value = selectedOptionValue;
}
</script>
<div>
<select onChange="copyTextValue(this);">
<option value="0">select phone</option>
<option value="1">select first phone</option>
<option value="2">select second phone</option>
<option value="3">select third phone</option>
<option value="4">select fourth phone</option>
</select>
</div>
<td><input type="text" id="destination"> </td>
here you are also trying to avoid to pass any value to the textbox when the first element is selected. #kryptur's answer is also correct, but this is simpler.
You're using Thymeleaf. For these you to create a form to send you data to the server.
Follow this link for documentation for your exact problems.
https://www.thymeleaf.org/doc/tutorials/2.1/thymeleafspring.html#creating-a-form
As Frameworks like Thymeleaf usually store state on the server which means you update server first - and then your UI gets updated.
what value return is the value of the select field what you need to do is get the text of selected option i.e
function copyTextValue() {
var selectNode = document.getElementById("source");
enter code here
document.getElementById("destination").value =
selectNode .options[selectNode .selectedIndex].textContent;
}
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.
<body>
<form action="http://TESTPLANETPRESS:8080/ObtainQuote" method="GET" >
<fieldset>
<legend>Location</legend>
<select id="country" class="source" onchange="updateSelectTarget()">
<option value="England">England</option>
<option value="France">France</option>
<option value="Germany">Germany</option>
</select>
<select id="England">
<option value="Birmingham">Birmingham</option>
<option value="Liverpool">Liverpool</option>
<option value="London">London</option>

<select id="France" class="hidden">

<input type="submit" value="Submit">
</form>
<script>
function updateSelectTarget () {
var id = this.options[this.selectedIndex].value;
var targets = this.parentNode.getElementsByTagName("select");
var len = targets.length;
for (var i = len - 1; i > 0; --i) {
if (targets[i].id == id) {
targets[i].style.display = "block";
}
else {
targets[i].style.display = "none";
}
}
}
function initChangeHandler () {
var el = document.getElementById("country");
el.onchange = updateSelectTarget;
el.onchange();
}
window.onload = initChangeHandler;
</script>
</body>
Current XML result, (Does not include the results from the two drop downs).
<?xml version="1.0"?>

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 want a drop down element where user can select from available options or select enter value option which in turn allows to enter value.
I specifically want that user can enter value only when they select "Enter a value " option.
Here is what I have tried so far.
HTML-
<div class="ginput_container">
<select name="input_4" id="input_1_4" class="medium gfield_select" tabindex="15">
<option value="0">None</option>
<option value="155">1-70</option>
<option value="185">71-250</option>
<option value="*">Enter value</option>
</select>
<input type="text" value="None" class="holder" >
</div>
JavaScript-
jQuery(".gfield_select").change(function() {
var val = jQuery(this).val();
var enter = jQuery(this).parent().find('option:selected').text();
var x = jQuery(this).parent();
if (enter ==="Enter a value" || enter === "Enter value"){
var holder = x.find('.holder');
holder.val('');
holder.prop('disabled',false);
holder.focus();
} else {
x.find('.holder').val(x.find('option:selected').text());
}
});
JS fiddle
however it wont work properly if i click the enter value option again.
I think there are many plugins that do what you want but if you want to create your own, it's a basic and simple solution.
You can create a select and a textbox with display:none like this:
<select id="ddlDropDownList">
<option value="1">Item 1</option>
<option value="2">Item 2</option>
<option value="3">Item 3</option>
<option value="-1">Enter Value</option>
</select>
<input id="txtTextBox" type="text" />
<style>
#txtTextBox{
display:none;
}
</style>
then try this JQuery:
$("#ddlDropDownList").change(function(){
if($(this).val() == '-1'){
$("#txtTextBox").fadeIn();
}else{
$("#txtTextBox").fadeOut();
}
});

I have forked your JSFiddle to http://jsfiddle.net/pwdst/4ymtmf7b/1/ which I hope does what you wanted to achieve.
HTML-
<div class="ginput_container">
<label for="input_1_4">Select option</label>
<select class="medium gfield_select" id="input_1_4" name="input_4" tabindex="15">
<option value="0">None</option>
<option value="155">1-70</option>
<option value="185">71-250</option>
<option value="*">Enter value</option>
</select>
<div>
<label class="hidden-label" for="input_1_4_other">Other value</label>
<input class="holder" id="input_1_4_other" disabled="disabled" name="input_1_4_other" placeholder="None" type="text" />
</div>
</div>
JavaScript-
jQuery(".gfield_select").change(function() {
var $this = jQuery(this);
var val = $this.val();
var holder = $this.parent().find('.holder');
if (val === "*"){
holder.val('');
holder.removeAttr('disabled');
holder.focus();
} else {
holder.val(this.options[this.selectedIndex].text);
holder.attr('disabled', 'disabled');
}
});
When the "Enter value" option is chosen then the input box is enabled, value set to an empty string, and it is focused. If another option is chosen then the text input is disabled again, and the text value from the select list is used.
Thanks guys
I guess i have found my answer

I have here selectbox with option value USA and OTHERS. What I need is if I choose OTHERS on Selectbox1 the Selectbox2 should be display none and textbox1 comes out. Other problem also is it's name field, If I POST the value of name="cboState" . How to remove the name of a field? Any help will appreciate.
<form action="try.php" method="POST">
<select id="cboCountry">
<option value="USA">USA</option>
<option value="OTHERS">OTHERS</option>
</select>
Selectbox 2
<select id="cboState" name="cboState">
<option value="Alabama">Alabama</option>
</select>
Textbox 1
<input type="text" id="cboState" name="cboState"/>
<input type="submit">
</form>
Try this
HTML
<select id="cboCountry">
<option value="USA">USA</option>
<option value="OTHERS">OTHERS</option>
</select>
<select id="cboState" name="cboState">
<option value="Alabama">Alabama</option>
</select>
<input type="text" id="txtcboState" name="cboState" style="display:none;"/>
JS
$("#cboCountry").change(function() {
if ( $(this).val() == "OTHERS") {
$("#cboState").hide();
$("#txtcboState").show();
}
else{
$("#cboState").show();
$("#txtcboState").hide();
}
});
Note: ID Must be unique for each element.
To remove The name attribute of input, you can use the following
$("#txtcboState").removeAttr('name');
DEMO HERE
Something like this?
$("#selectbox1").onchange(function() { selectionChanged();});
function selectionChanged() {
if ( $("#selectbox1").val() == "other") {
$("#selectbox2").hide();
$("#textBox1").show();//should already be hidden
}
}
Make sure the IDs for your elements are unique.
