I have created with javascript and I get a result of a string.I get that result on my html code
<div id="results"></div>
Next,I want when I select for example Red to check if it is the the same thing (string), the select option - > Red with the string of this code
<div id="results"></div>
I was trying to do it but I failed.It is not working not even sure ,if I press the submit button I will send the string.
<div id="results"></div>
<form method="post" >
<select >
<option value="">--Please choose an option--</option>
<option value="R">Red</option>
<option value="B">Black</option>
</select>
<input id="results" type="submit" value="results"/>
It appears that you want to check whether the selected option is equal to the text value of the div #results. You can achieve this effect like so:
$(document).ready(function(){
var select = $("select");
$("input[type=\"button\"]").click(function(){
var text = select.find(":selected").text();
if(text==$("#results").text()){
$("#results").html(text+" is equal!");
}else{
$("#results").html(text+" is not equal :(");
}
});
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div id="results">Red</div>
<form method="post" >
<select >
<option value="">--Please choose an option--</option>
<option value="R">Red</option>
<option value="B">Black</option>
</select>
<input id="results" type="button" value="results"/>
</form>
A form is going to be Sending data somewhere, it would be best to remove the form, leaving the select and button elements. In the button add the code onclick='myFunction() ; when the button is clicked it will run the javascript function called myFunction(). Also you need to give the select a Id. I'm using selectInput
<script>myFunction() { document.getElementById('result').innerHTML = document.getElementById('selectInput').value;} </script>
Now when ever the button is pressed it will set the content of the div equal to the value entity in the selected select box option
You lack an action attribute.
<form method="post" action="path/to/file">
<select name="select">
<option value="">--Please choose an option--</option>
<option value="R">Red</option>
<option value="B">Black</option>
</select>
<input type="submit" value="Get Results" />
</form>
Use a function, and a regular button. No form is needed.
<button onclick='func()'></button>
const func = () => {...}

I would like to pass the text portion (not the value) of a form Select-Option to a hidden text-input field within the same form when the user makes a selection.
I have explored some java and PHP 'examples' I found in my research, but none of them seem to work for me.
I have posted a raw example of the form to see if anyone can lead me to water. Any help wouold be appreciated.

<form action="fruitBasket.php" method="post" enctype="multipart/form-data">
<select id="fruitSelector" name="fruitSelector">
<option value="0" selected="selected" disabled="disabled">Select Fruit</option>
<option value="1">Grapes</option>
<option value="2">Strawberries</option>
<option value="3">Peaches</option>
<option value="4">Blueberries</option>

It's not as easy as getting the selected option's value, which can be retrieved simply as selectElement.value, yet it's not difficult at all.
selectElement.options will give you an array of ALL the options inside the select element.
You will find the selected option's index to be selectElement.selectedIndex.
With that said, you can access to the selected option like this: selectElement.options[selectElement.selectedIndex].
Finally, you can get the text property like this: selectElement.options[selectElement.selectedIndex].text
Here's the code:
// THIS CONSTANT REPRESENTS THE <select> ELEMENT
const theSelect = document.getElementById('fruitSelector')
// THIS LINE BINDS THE input EVENT TO THE ABOVE select ELEMENT
// IT WILL BE EXECUTED EVERYTIME THE USER SELECTS AN OPTION
theSelect.addEventListener('input', function() {
// THIS IS HOW YOU GET THE SELECTED OPTION'S TEXT
let selectedOptText = theSelect.options[theSelect.selectedIndex].text
// FINALLY, THIS COPIES THE ABOVE TEXT TO THE INPUT ELEMENT:
document.querySelector('.hiddenField').value = selectedOptText;
})
<form action="fruitBasket.php" method="post" enctype="multipart/form-data">
<select id="fruitSelector" name="fruitSelector">
<option value="0" selected="selected" disabled="disabled">Select Fruit</option>
<option value="1">Grapes</option>
<option value="2">Strawberries</option>
<option value="3">Peaches</option>
<option value="4">Blueberries</option>
</select>
<br>
<br>
<input type="text" class="hiddenField" name="hiddenField" placeholder="Selected fruit appears
here.">
</form>
well if you want to pass the text portion you should add the names as the values too like
---
code
---
<option value="Grapes">Grapes</option>
<option value="Strawberries">Strawberries</option>

It's my first contact with js so please don't hate me
I have something like this:
function Zmiana(isChecked) {
document.getElementById('test').type = 'text';
}
<div class="dropdown">
<select id="test" name="producent" class="dropdown-select">
<option value="Apple">Apple</option>
<option value="Samsung">Samsung</option>
<option value="Lenovo">Lenovo</option>
</select> <br>
</div>
But it doesn't work
You won't be changing the select into a textbox. Instead, you'll have both a select and a textbox. The checkbox will simply determine which is shown.
Also, your select should include a first choice that is not considered valid so that you don't get a submitted value that the user didn't choose.
.hidden { display:none; }
<input type="checkbox" id="check">Check to enter text directly
<div class="dropdown">
<select id="test" name="producent" class="dropdown-select">
<option value="">--- Choose ---</option>
<option value="Apple">Apple</option>
<option value="Samsung">Samsung</option>
<option value="Lenovo">Lenovo</option>
</select>
<input id="data" class="hidden">
</div>
<script>
let text = document.getElementById('data');
let check = document.getElementById("check");
let select = document.getElementById("test");
// You must set up your function to handle the
// click event of the checkbox
check.addEventListener("click", Zmiana);
function Zmiana(){
// Add or remvoe the hidden class based on
// whether it's already in use
select.classList.toggle("hidden");
text.classList.toggle("hidden");
}
</script>
I'm trying to set the value of a dropdown list based on another dropdown list value inside Angular and using jQuery, it works and it auto selects the wanted value but it doesn't add the value to the database after submitting. I'm sure everything is fine concerning the database connection because choosing any other selected value (for example euro in this case) is added to database.
$(document).ready(function() {
$("#country").change(function() {
var val = $(this).val();
if (val == "usa") {
$("#currency").val("dollar");
}
});
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<form (ngSubmit)="onSubmit()">
<select id="country" name="country">
<option value="usa">usa</option>
<option value="france">france</option>
</select>
<select id="currency" name="currency">
<option value="dollar">dollar</option>
<option value="euro">euro</option>
</select>
<button type="submit" class="btn btn-primary">submit </button>
</form>
NB: Dollar becomes selected but when submitting it's not added to database, whereas if I remove the jQuery function and choose manually the currency , it adds to the database and everything is fine .
The jQuery code seems to be good... but my question is, why are you using jQuery to update a form in Angular.
Did you evaluate use tempalte-driven or reactive forms instead? Below you can find your form written as template driven.
<form (ngSubmit)="onSubmit()">
<select id="country" name="country" (change)="onCountryChange()" [(ngModel)]="selectedCountry">
<option
*ngFor="let country of countries"
[value]="country">
{{ country }}
</option>
</select>
<select id="currency" name="currency" [(ngModel)]="selectedCurrency">
<option
*ngFor="let currency of currencies"
[value]="currency">
{{ currency }}
</option>
</select>
<button type="submit" class="btn btn-primary">submit </button>
</form>
And in this plunkr you can find the full example using template-driven form... but if I where you, I would go for the reactive form approach.
I ended by this code after helping with many thanks of others here in this website. Now, in the following code of submitting the form, I want the value of the hidden input field to be instead of Other when shown the result.
<form action="" method="post">
<div class="row">
<div class="col-sm-8 col-sm-offs et-2">
<select class="form-control" name="country" id="country" required >
<option value="">Please select your country</option>
<option value="A">Country A</option>
<option value="B">Country B</option>
<option value="C">Country C</option>
<option value="Other">Other</option>
</select>
<input type ="text" id="country_other" style="display:none">
<button type="submit" class="btn btn-gpsingh">Next</a>
</div>
</div>
</form>
<script>
$("#country").change(function(){
var value = this.value;
if(value =='Other')
{
$("#country_other").show();
$("#country_other").attr('required', false);
}
else
{
$("#country_other").hide();
$("#country_other").val('');
$("#country_other").attr('required', false);
}
});
</script>
Something you could try, if I understood correctly, would be to remove the name attribute from the SELECT menu if the chosen value is other and assign the name attribute instead to the text input element - when the form is submitted the item in the POST array with the name of country would come from the text field and not the select menu...
$('#country').change(function(){
if( this.value == 'Other' ){
$('#country_other').show();
$('#country_other').attr('required', false);
/* remove name from select & add to text field */
$('#country_other').attr('name', $(this).attr('name') );
$(this).removeAttr('name');
} else {
$('#country_other').hide();
$('#country_other').val('');
$('#country_other').attr('required', false);
/* remove name attribute from text field and assign back to select menu */
$(this).attr('name', $('#country_other').attr('name') );
$('#country_other').removeAttr('name');
}
});
I have a form that I wish to change the action of, depending on what value a user selects in a drop down box.
The example code below shows each option value, I want to change the form action to whatever option value is chosen on a button press, how can I do this with JavaScript?
<form name ="form1" action="VariableFormAction" method ="post" target="_blank">
<select name="formchoice">
<option value="/formaction1">function 1</option>
<option value="/formaction2">function 2</option>
<option value ="/formaction3">function 3</option>
</select>
<input type="submit" value="Go" class="button">
</form>
In order to do this you need to specify an onSubmit JavaScript event handler on the form that retrieves the value of the select list and updates the form action.
You can do this using the following code.
//Add onSubmit() event handler to form to call JavaScript method when the form is submitted.
<form name ="form1" onSubmit="actionOnSubmit()" method ="post" target="_blank">
<select id="formchoice" name="formchoice">
<option value="/formaction1">function 1</option>
<option value="/formaction2">function 2</option>
<option value ="/formaction3">function 3</option>
</select>
<input type="submit" value="Go" class="button">
</form>
<script>
function actionOnSubmit()
{
//Get the select select list and store in a variable
var e = document.getElementById("formchoice");
//Get the selected value of the select list
var formaction = e.options[e.selectedIndex].value;
//Update the form action
document.form1.action = formaction;
}
</script>
Note, for this to work you will need to make sure the select list has an id as you are using the document.getElementById[] JavaScript method to retrieve the value of the control.
You could also call the JavaScript in the OnChange() event of the control. The issue with this is that it implies that the value has changed before the form is submitted. If the user simply left the default select list value it is possible that the OnChange() event would never fire.
You can try like following.
function selectChanged(ctrl) {
var val = ctrl.value;
var frm = document.getElementById('form1');
frm.action = val;
}
<form id="form1" name="form1" action="/formaction1" method="post" target="_blank">
<select name="formchoice" onchange="selectChanged(this)">
<option value="/formaction1">function 1</option>
<option value="/formaction2">function 2</option>
<option value ="/formaction3">function 3</option>
</select>
<input type="submit" value="Go" class="button">
</form>
Use on change attribute.
<select name="forma" onchange="location = this.value;">
<option value="Home.php">Home</option>
<option value="Contact.php">Contact</option>
<option value="Sitemap.php">Sitemap</option>
</select>
