onchange works fine when selecting items from a datalist. The problem arises when I want to modify some element. Then they add another onchange and the modified text disappears once it is refreshed.
What should he do to save the modification when adding another onchange?
function information(ele){
var address1 = document.getElementsByClassName('test2');
for(var i=0; i<address1.length; i++){
if( ele.value == "test4"){
address1[i].value = "test5";
} else if (ele.value == "test6"){
address1[i].value = "test7";
} else if (ele.value == "test8"){
address1[i].value = "test9";
}
}
}
<div class="form grup information">
<lable for="dates-full.names"> Names full</lable>
<input name="dates-full.names" list="dates-full.names" type="text"
class="form grup test1" onchange="information(this)">
<datalist type="text" id="dates-full.names">
<option value="test4">
<option value="test6">
<option value="test8">
</datalist>
</div>
<div class="form grup test2">
<lable for="power-full.adress"> Adress full</lable>
<input id="test2" name="dates-full.adress" list="dates-full.adress" type="text"
class="form grup test2">
<datalist type="text" id="dates-full.adress">
<option value="test5">
<option value="test7">
<option value="test9">

Please check above solution. It will enable input box at initial level. when you select one value, then it will disable input box.
I'm trying to change the value of my input box by changing two different select options.
The first select box is product_type with two different data attributes on the options: data-price and data-price_c.
The second Select box pay_type is to selecting between data-price or data-price_c, to update the value of lprice.
This is what I've tried:
var sp = document.getElementById('select_product');
var lp = document.getElementById('lprice');
var count = document.getElementById('count');
var fp = document.getElementById('price');
var pt = document.getElementById('paytype');
var selected_type = pt.options[pt.selectedIndex];
sp.onchange = function(){
var selected = sp.options[sp.selectedIndex];
if (selected_type === 1){
lp.value = selected.getAttribute('data-price');
} else {
lp.value = selected.getAttribute('data-price_c');
}
fp.value = "";
};
sp.onchange();
count.onchange = function(){
fp.value = lp.value * count.value;
}
<div>
<label for="select_product">Select Product</label>
<select name="product_id" id="select_product" onchange="update();">
<option value="1" data-price="10000" data-price_c="11000">Product 1</option>
<option value="2" data-price="20000" data-price_c="21000">Product 2</option>
<option value="3" data-price="30000" data-price_c="31000">Product 3</option>
</select>
</div>
<div>
<label for="paytype">Pay type:</label>
<select name="paytype" id="paytype">
<option value="1">Cash</option>
<option value="2">Dept</option>
</select>
</div>
<div>
<label for="lprice">Single Price:</label>
<input type="text" name="lprice" id="lprice" class="form-control" tabindex="1" readonly/>
</div>
<div>
<label for="count">Count:</label>
<input type="number" name="count" id="count" class="form-control" tabindex="1" />
</div>
<div>
<label for="price">Full Price:</label>
<input type="text" name="price" id="price" class="form-control" tabindex="1" readonly/>
</div>
I hope I understated you correctly what needs to be done from code and explanation:
Your first problem was that you had your selected_type outside of you onchange function so it wasn't getting the changed options onchange.
Second is that you where trying to compare values 1 & 2 with element without actually extracting those values from element (missing .value on selected_type)
I assumed you will need to update the values on your Pay type change too as well as Select Product, so there is nit trick to wrap both HTML selects into one div in this case div id="wrapper" and that will listen on both selects and call function if any of them are changed. So now you call it on wrapper.onchange.
I would also advise to put your calculation fp.value = lp.value * count.value; inside this function to update total price on change of any of those elements so I wrapped your Count: into wrapper div.
Hope this helps.
var sp = document.getElementById('select_product');
var lp = document.getElementById('lprice');
var count = document.getElementById('count');
var fp = document.getElementById('price');
var pt = document.getElementById('paytype');
var wrapper=document.getElementById('wrapper');
wrapper.onchange = function(){
var selected = sp.options[sp.selectedIndex];
var selected_type = pt.options[pt.selectedIndex].value;
if (selected_type === "1"){
lp.value = selected.getAttribute('data-price');
}
if (selected_type === "2"){
lp.value = selected.getAttribute('data-price_c');
}
fp.value = "";
fp.value = lp.value * count.value;
};
wrapper.onchange();
<div id="wrapper">
<div>
<label for="select_product">Select Product</label>
<select name="product_id" id="select_product" >
<option value="1" data-price="10000" data-price_c="11000">Product 1</option>
<option value="2" data-price="20000" data-price_c="21000">Product 2</option>
<option value="3" data-price="30000" data-price_c="31000">Product 3</option>
</select>
</div>
<div>
<label for="paytype">Pay type:</label>
<select name="paytype" id="paytype">
<option value="1">Cash</option>
<option value="2">Dept</option>

<div>
<label for="lprice">Single Price:</label>

I have a textarea element that is not displayed. If the user selects "Other" option in the select element, the textarea should show, but it is not showing with the below code.
The following is my select element :
<select class="form-control" name="feed" id="feed" value="" style="width:540px">
<option selected="selected" disabled="true">Please select</option>
<!-- <option></option> -->
<option value="Excellent" id="Excellent"> All text is excellent</option>
<option value="Other" id="Other" onclick="showHide(this)"
>Other feedback (free text)</option
>
</select>
The following is my textarea element :
<div class="form-group">
<label for="fb_text"></label>
<textarea
class="form-control"
name="fb_text"
id="fb_text"
rows="5"
placeholder="Describe yourself here..."
value=""
style="width:540px;display:none"
></textarea>
</div>
The following is my JS :
function showHide(elm) {
var Fbtext = document.getElementById("fb_text");
if (document.getElementById("feed").value == "Other") {
Fbtext.classList.remove("hide");
}
}
You can pass value from select using onchangeevent to your function and check if that value is equals to Others if yes display textarea else hide it. Working example :
function showHide(elm) {
if (elm == "Other") {
//display textbox
document.getElementById('fb_text').style.display = "block";
} else {
//hide textbox
document.getElementById('fb_text').style.display = "none";
}
}
<select class="form-control" name="feed" id="feed" value="" onchange="showHide(this.value)" style="width:540px">
<option selected="selected" disabled="true">Please select</option>
<!-- <option></option> -->
<option value="Excellent" id="Excellent"> All text is excellent</option>
<option value="Other" id="Other">Other feedback (free text)</option>
</select>
<div class="form-group">
<label for="fb_text"></label>
<textarea class="form-control" name="fb_text" id="fb_text" rows="5" placeholder="Describe yourself here..." value="" style="width:540px;display:none"></textarea>
</div>
Add change event to the select element, see if the selected option is 'Other', hide the text area else show.
const textareaEle = document.querySelector('textarea');
document.querySelector('select').addEventListener('change', function() {
textareaEle.style.display = (this.value == 'Other') ? 'block' : 'none';
});
<link href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css" rel="stylesheet"/>
<select class="form-control" name="feed" id="feed" value="" style="width:540px">
<option selected="selected" disabled="true">Please select</option>
<!-- <option></option> -->
<option value="Excellent" id="Excellent"> All text is excellent</option>
<option value="Other" id="Other">Other feedback (free text)</option>
</select>
<div class="form-group">
<label for="fb_text"></label>
<textarea class="form-control hide" name="fb_text" id="fb_text" rows="5" placeholder="Describe yourself here..." value="" style="width:540px;"></textarea>
</div>
I have not checked but I understand in your code you try to remove a class (hide) that you have not assigned, because you hide the textarea with the attribute style
Please try this example, I understand in your example you use bootstrap, for demonstration I have added hide
const feed = document.querySelector('#feed');
const fbtext = document.querySelector('#fb_text');
feed.addEventListener('change', handleChange);
function handleChange(event) {
const value = event.target.value;
if (value === 'Other') {
fbtext.classList.remove('hide');
return false;
}
fbtext.classList.add('hide');
}
.hide {
display: none;
}
<select
class="form-control"
name="feed"
id="feed"
value=""
style="width:540px"
>
<option selected="selected" disabled="true">Please select</option>
<option value="Excellent" id="Excellent"> Excellent</option>
<option value="Other" id="Other">Other</option>
</select>
<div class="form-group">
<label for="fb_text"></label>
<textarea
class="form-control hide"
name="fb_text"
id="fb_text"
rows="5"
placeholder="Describe yourself here..."
></textarea>
</div>
So I'm trying to change a select box's style if the value is not changed ie. the user has not selected anything. That yesnoCheck is a function which shows an additional input field if the choice "other" is selected. I don't think it affects this form validation though. This same kind of validation works fine with an input field but it won't work with a select box.
I've also treid selectedIndex == 0 but it doesn't work either.
HTML:
<form name="myForm" method="post" action="" onsubmit="return(validate());">
<label for="lastname">Sukunimesi:</label>
<input type="text" id="lastname" name="lastname" /><br />
<select id="car" name="car" onchange="javascript:yesnoCheck()">
<option id="noCheck" value="none">Valitse automerkkisi</option>
<option id="noCheck" value="1">Lada</option>
<option id="noCheck" value="2">Mosse</option>
<option id="noCheck" value="3">Volga</option>
<option id="noCheck" value="4">Vartburg</option>
<option id="yesCheck" value="other">Muu</option>
</select>
<input type="submit" value="Submit" />
</form>
JS:
<script type="text/javascript">
function yesnoCheck() {
if (document.getElementById("yesCheck").selected) {
document.getElementById("ifYes").style.display = "block";
}
else document.getElementById("ifYes").style.display = "none";
}
function validate() {
if (document.myForm.lastname.value.length < 3) {
document.getElementById("lastname").className = "required";
return false;
}
if (document.myForm.car.value == "none") {
document.getElementById("car").className = "required";
return false;
}
alert ("Everything is fine!");
}
</script>
Your code works check your form name and make sure your form exists before the script is run.
function check(){
if (document.myForm.car.value == "none") {
document.getElementById("car").style.border = "1px solid #900";
document.getElementById("car").style.backgroundColor = "#ff9";
return false;
}
}
<form name="myForm">
<select id="car" name="car" onchange="javascript:yesnoCheck()">
<option id="noCheck" value="none">Valitse automerkkisi</option>
<option id="noCheck" value="1">Lada</option>
<option id="noCheck" value="2">Mosse</option>
<option id="noCheck" value="3">Volga</option>
<option id="noCheck" value="4">Vartburg</option>
<option id="yesCheck" value="other">Muu</option>
</select>
</form>
<button onclick="check()">Run script</button>
So the solution was to delete return false; from the function.
I created a form with cal() in it, so people can choose options and then it would calculate the answer depending on what they have chosen.
But I would like to insert a button at the end that would call the result. So when people have chosen their options they would click the submit button and it would give them the right answer depending on their choice.
I haven't been able to do it. I tried an input type button but I don't know how to call the rest.
Here's my code:
<script>
function cal() {
var pl = document.form1.template.value;
var resultat = pl;
document.form1.tresultat.value = resultat;
document.formfin.tresultatfin.value = calfin();
}
function cal2() {
var pl2 = document.form2.envoi.value;
var resultat2 = pl2;
document.form2.tresultat2.value = resultat2;
document.formfin.tresultatfin.value = calfin();
}
function cal3() {
var pl3 = document.form3.article.value;
var tl3 = document.form3.ecrit.value;
var resultat3 = pl3*tl3;
document.form3.tresultat3.value = resultat3;
document.formfin.tresultatfin.value = calfin();
}
function calfin() {
var r1 = form1.tresultat.value;
var r2 = form2.tresultat2.value;
var r3 = form3.tresultat3.value;
return (parseFloat(r1)+(parseFloat(r2)*parseFloat(r3)));
}
</script>
<form name="form1">
<label for="template">Template :</label>
<select name="template" onChange="cal()">
<option value="500">Yes
<option value="800">No
<option value="2900">Maybe
</select>
<input type="hidden" value="0" name="tresultat">
</form>
<br><br><br>
<form name="form2">
<label for="envoi">Quantité d'envoi annuel :</label>
<select name="envoi" onChange="cal2()">
<option value="2">2
<option value="3,6">4
<option value="5,1">6
<option value="6,4">8
<option value="9">12
</select>
<input type="hidden" value="0" name="tresultat2">
</form>
<br><br><br>
<form name="form3">
<label for="article">Articles par infolettre :</label>
<select name="article" onChange="cal3()">
<option value="1">1
<option value="2">2
<option value="3">3
</select>
<label for="ecriture"> Écriture des articles :</label>
<select name="ecrit" onChange="cal3()">
<option value="50">X
<option value="300">Y
<option value="200">Z
</select>
<input type="hidden" value="0" name="tresultat3">
<br><br><br>
<form name="formfin">
<label for="total"> Total :</label>
<input type="text" value="0" name="tresultatfin">
</form>
All my functions seem to work. They calculate what I want, only the button that would call the answer is missing.
Thanks a lot for any help!
Just add a button in your form
<form name="formfin">
<label for="total"> Total :</label>
<input type="text" value="0" name="tresultatfin">
**<input type="button" onclick="cal()" value="Calculer" />**
</form>
