Hope you understand my question. Sos for bad english
There is a HTML "range" input, but it's not the most common input method out there and will require some javascript with it. Other than that, the only reasonable method is PHP. Though, if you do use PHP, you can copy and paste the HTML and then insert it into your HTML file if you don't want that page to have PHP. Below are a few HTML only examples. May not work in all browsers, so your server side code should always validate. http://jsfiddle.net/h96nU/1/
The below code shows a few inputs using various methods. The range input will update to show the range value that is currently selected. The last number input uses the HTML5 pattern attribute.
input:invalid {
border: 1px solid red;
}
input:valid {
border: 1px solid green;
}
<div>
<input id="range" type="range" min="1" max="120" step="1" />
<span id="range_value">0</span>
</div>
<div>
<input type="number" />
</div>
<div>
<input type="text" />
</div>
<div>
<input type="number" min="1" max="120" step="1" id="n1" name="age" pattern="\d+" />
</div>
var input = document.getElementById('range');
input.addEventListener('change',input_change,false);
function input_change(e) {
var target = e.target || e.srcElement;
var value = target.value;
var showdiv = document.getElementById('range_value');
showdiv.textContent = value;
}
More about Data Validation in HTML can be found at https://developer.mozilla.org/en-US/docs/Web/Guide/HTML/Forms/Data_form_validation
For PHP method of an age input loop, look below.
<?php
$min = 1;
$max = 100;
echo '<select name="age">';
for($i = $min; $i <= $max; $i++) {
echo '<option value="'.$i.'">'.$i.'</option>';
}
echo '</select>';
?>
If you are using PHP for example you could do it like this:
<?php
$myArray = ['USA','Australia','ETC ETC ETC'];
echo '<select name="country">';
foreach ($myArray as $value) {
echo '<option value="'.$value.'">';
echo $value;
echo "</option>";
}
echo "</select>";
?>
The output of this example would be :
<select name="country">
<option value="USA">USA</option>
<option value="Australia">Australia</option>
<option value="ETC ETC ETC">ETC ETC ETC</option>
</select>
For your age selectbox:
<?php
$maxAge = 99;
echo '<select name="age">';
for ($i=1; $i < $maxAge; $i++) {
echo '<option value="'.$i.'">';
echo $i;
echo "</option>";
}
echo "</select>";
?>
I intend to "bring back" some information about a user in a form, so I have to place that info into the right inputs. Some are in a select structure.
I want to select the right option from that select structure, and for that I do like this:
<select class="m-wrap span12" name="gender">
{if $obj eq '1'}
<option value="">Seleccione</option>
<option value="1" selected>Hombre</option>
<option value="2">Mujer</option>
{elseif $obj eq '2'}
<option value="">Seleccione</option>
<option value="">Hombre</option>
<option value="2" selected>Mujer</option>
{else}
<option value="0" selected>Seleccione</option>
<option value="">Hombre</option>
<option value="2">Mujer</option>
{/if}
</select>
But I want to make it shorter so I don't repeat code lines. I have tried this but with no success:
<select class="m-wrap span12" name="gender" id="{$obj}">
<option value="1" id="1">Hombre</option>
<option value="2" id="2">Mujer</option>
<option value="0" id="3">Seleccione</option>
</select>
I'm using smarty template and codeigniter.
Thanks in advance, I'm new to programming.
<select class="m-wrap span12" name="gender">
<option value="1" id="1" <?=($obj == 1) ? 'selected="selected"' : '';?>>Hombre</option>
<option value="2" id="2" <?=($obj == 2) ? 'selected="selected"' : '';?>>Mujer</option>
<option value="0" id="3" <?=($obj == 3) ? 'selected="selected"' : '';?>>Seleccione</option>
</select>
In this case I'm using just one line of code with the help of form_helper
<div id='myform'>
{form_open('controller/method')}
{form_dropdown('gender',$genders,set_value('gender',$obj),'class = "m-wrap span8 chosen" data-with-diselect="1"')}
{form_close()}
</div>
Where
$genders is list of genders assigned to smarty variable like
$genders = array('0' => 'Seleccione', '1' => 'Hombre', '2' => 'Mujer')
'gender' is name attribute value of select tag
set_value() function sets the option selected where option value is equal to $obj
and other class like attributes of select tag
Note
form_helper must be loaded before display of a template
You can do this by making the option's hidden HTML value equal to that option's position within the select list, beginning with zero; then storing the server side value; then setting the selectedIndex of the menu equal to the stored value.
<select class="m-wrap span12" name="gender" id="gender_field">
<option value="0" selected>Seleccione</option>
<option value="1">Hombre</option>
<option value="2">Mujer</option>
</select>
<input type="hidden" id="gender_obj" value="{$obj}" />
<!-- the above line passes the server-side variable into the
-- HTML for JavaScript to use -->
<script>
(function (){
var gender_field = document.getElementById('gender_field'),
gender_obj = document.getElementById('gender_obj'),
n;
if (!gender_field || !gender_obj) return;
n = gender_obj.value - 0;
/* will be NaN if nothing (or nothing numerical) is there,
* such as on the first visit */
gender_field.selectedIndex = gender_field.options[n] ? n : 0;
})();
</script>
I could finally achieve this. Using Smarty the sintax can be:
<select class="m-wrap span8 chosen" name="gender" data-with-diselect="1" value="">
<option value=" " {if $okInfo['gender'] eq ' '}selected{/if}>Seleccione</option>
<option value="1" {if $okInfo['gender'] eq '1'}selected{/if}>Hombre</option>
<option value="2" {if $okInfo['gender'] eq '2'}selected{/if}>Mujer</option>
</select>
So that way, if the user selects from a dropdown menu a certain option but then doesn't pass form validation, the data that he entered and it's ok should be retreive in the same way. So for a select html tag, this is the way of "bringing back" the data he had entered.
I want to change the select option selected to another value.
I.e.,
<select id="myid">
<option value="1" selected="selected">1 </option>
<option value="2" >2 </option>
<option value="3" >3 </option>
<option value="4" >4 </option>
</select>
I have to trigger a change in this select and select the 3rd option I have the value how can I do it.?
I am adding an option each time by a function and I want after each addition of the option, I want it to be selected to do further activities.
To change by index
<input type="button" value="Change Select" onclick="changeSelect(3)" />
function changeSelect(x) {
document.frm.myid.selectedIndex = x-1;
}
to change by value
<input type="button" value="Change Select" onclick="changeSelect1(3)" />
function changeSelect1(x) {
var myid = document.getElementById('myid');
var st = myid.options;
for(var i=0; i<st.length; i++) {
if(st[i].value == x) {
myid.selectedIndex = i;
}
}
}
function Change() {
for (i = 0; i < document.getElementById('ddStream').options.length; i++) {
if (document.getElementById('ddStream').options[i].value == 1)
document.getElementById('ddStream').selectedIndex = i;
}
alert(document.getElementById('ddStream').selectedIndex);
return false;
}
<select id="ddStream" onchange="return Change()">
<option value="">EEE</option>
<option value="">ECE</option>
<option value="">CSE</option>
<option value="1">E&I</option>
</select>
This is the basic syntax.. The other things that you have mentioned will go by the logic u write.. Eg, to select the last option that u add dynamically,
document.getElementById('ddStream').selectedIndex = document.getElementById('ddStream').options.length -1
selected="selected" selects the option you want, just put it on the 3rd option tag
E.g.
<select id="myid">
<option value="1">1 </option>
<option value="2">2 </option>
<option value="3" selected="selected">3 </option>
<option value="4">4 </option>
</select>
I thought that adding a "value" attribute set on the <select> element below would cause the <option> containing my provided "value" to be selected by default:
<select name="hall" id="hall" value="3">
<option>1</option>
<option>2</option>
<option>3</option>
<option>4</option>
<option>5</option>
</select>
However, this did not work as I had expected. How can I set which <option> element is selected by default?
Set selected="selected" for the option you want to be the default.
<option selected="selected">
3
</option>
In case you want to have a default text as a sort of placeholder/hint but not considered a valid value (something like "complete here", "select your nation" ecc.) you can do something like this:
<select>
<option value="" selected disabled hidden>Choose here</option>
<option value="1">One</option>
<option value="2">Two</option>
<option value="3">Three</option>
<option value="4">Four</option>
<option value="5">Five</option>
</select>
Complete example:
<select name="hall" id="hall">
<option>1</option>
<option>2</option>
<option selected>3</option>
<option>4</option>
<option>5</option>
</select>
I came across this question, but the accepted and highly upvoted answer didn't work for me. It turns out that if you are using React, then setting selected doesn't work.
Instead you have to set a value in the <select> tag directly as shown below:
<select value="B">
<option value="A">Apple</option>
<option value="B">Banana</option>
<option value="C">Cranberry</option>
</select>
Read more about why here on the React page.
You can do it like this:
<select name="hall" id="hall">
<option> 1 </option>
<option> 2 </option>
<option selected> 3 </option>
<option> 4 </option>
<option> 5 </option>
</select>
Provide "selected" keyword inside the option tag, which you want to appear by default in your drop down list.
Or you can also provide attribute to the option tag i.e.
<option selected="selected">3</option>
if you want to use the values from a Form and keep it dynamic try this with php
<form action="../<SamePage>/" method="post">
<?php
$selected = $_POST['select'];
?>
<select name="select" size="1">
<option <?php if($selected == '1'){echo("selected");}?>>1</option>
<option <?php if($selected == '2'){echo("selected");}?>>2</option>
</select>
</form>
Best way in my opinion:
<select>
<option value="" selected="selected" hidden="hidden">Choose here</option>
<option value="1">One</option>
<option value="2">Two</option>
<option value="3">Three</option>
<option value="4">Four</option>
<option value="5">Five</option>
</select>
Why not disabled?
When you use disabled attribute together with <button type="reset">Reset</button> value is not reset to original placeholder. Instead browser choose first not disabled option which may cause user mistakes.
Default empty value
Every production form has validation, then empty value should not be a problem. This way we may have empty not required select.
XHTML syntax attributes
selected="selected" syntax is the only way to be compatible with both XHTML and HTML 5. It is correct XML syntax and some editors may be happy about this. It is more backward compatible. If XML compliance is important you should follow the full syntax.
I prefer this:
<select>
<option selected hidden>Choose here</option>
<option value="1">One</option>
<option value="2">Two</option>
<option value="3">Three</option>
<option value="4">Four</option>
<option value="5">Five</option>
</select>
'Choose here' disappears after an option has been selected.
An improvement for nobita's answer. Also you can improve the visual view of the drop down list, by hiding the element 'Choose here'.
<select>
<option selected disabled hidden>Choose here</option>
<option value="1">One</option>
<option value="2">Two</option>
<option value="3">Three</option>
<option value="4">Four</option>
<option value="5">Five</option>
</select>
Another example; using JavaScript to set a selected option.
(You could use this example to for loop an array of values into a drop down component)
<select id="yourDropDownElementId"><select/>
// Get the select element
var select = document.getElementById("yourDropDownElementId");
// Create a new option element
var el = document.createElement("option");
// Add our value to the option
el.textContent = "Example Value";
el.value = "Example Value";
// Set the option to selected
el.selected = true;
// Add the new option element to the select element
select.appendChild(el);
The selected attribute is a boolean attribute.
When present, it specifies that an option should be pre-selected when the page loads.
The pre-selected option will be displayed first in the drop-down list.
<select>
<option value="volvo">Volvo</option>
<option value="saab">Saab</option>
<option value="vw">VW</option>
<option value="audi" selected>Audi</option>
</select>
If you are in react you can use defaultValue as attribute instead of value in the select tag.
If you are using select with angular 1, then you need to use ng-init, otherwise, second option will not be selected since, ng-model overrides the defaul selected value
<select ng-model="sortVar" ng-init='sortVar="stargazers_count"'>
<option value="name">Name</option>
<option selected="selected" value="stargazers_count">Stars</option>
<option value="language">Language</option>
</select>
I would just simply make the first select option value the default and just hide that value in the dropdown with HTML5's new "hidden" feature. Like this:
<select name="" id="">
<option hidden value="default">Select An Option</option>
<option value="1">One</option>
<option value="2">Two</option>
<option value="3">Three</option>
<option value="4">Four</option>
</select>
value attribute of tag is missing, so it doesn't show as u desired selected. By default first option show on dropdown page load, if value attribute is set on tag.... I got solved my problem this way
This example has been tested to work with multiple <select> elements on the page, and can also work with normal text elements. It has not been tested for setting the value to more than one selection when <select multiple="true">, however you can probably modify this sample to support that.
Add an attribute data-selected to each <select> element and set the value(s) to the value of the option you wish to have selected.
Use javascript's querySelectorAll() to select all elements that have the custom attribute you just added.
In the following example, when run, the first <select> should show option with the value user as selected, and the second <select> should show the option with the value admin as selected.
document.querySelectorAll('[data-selected]').forEach(e => {
e.value = e.dataset.selected
});
<select data-selected="user" class="form-control" name="role">
<option value="public">
Pubblica
</option>
<option value="user">
Utenti
</option>
<option value="admin">
Admin
</option>
</select>
<select data-selected="admin" class="form-control" name="role2">
<option value="public">
Pubblica
</option>
<option value="user">
Utenti
</option>
<option value="admin">
Admin
</option>
</select>
I used this php function to generate the options, and insert it into my HTML
<?php
# code to output a set of options for a numeric drop down list
# parameters: (start, end, step, format, default)
function numericoptions($start, $end, $step, $formatstring, $default)
{
$retstring = "";
for($i = $start; $i <= $end; $i = $i + $step)
{
$retstring = $retstring . '<OPTION ';
$retstring = $retstring . 'value="' . sprintf($formatstring,$i) . '"';
if($default == $i)
{
$retstring = $retstring . ' selected="selected"';
}
$retstring = $retstring . '>' . sprintf($formatstring,$i) . '</OPTION> ';
}
return $retstring;
}
?>
And then in my webpage code I use it as below;
<select id="endmin" name="endmin">
<?php echo numericoptions(0,55,5,'%02d',$endmin); ?>
</select>
If $endmin is created from a _POST variable every time the page is loaded (and this code is inside a form which posts) then the previously selected value is selected by default.
This code sets the default value for the HTML select element with PHP.
<select name="hall" id="hall">
<?php
$default = 3;
$nr = 1;
while($nr < 10){
if($nr == $default){
echo "<option selected=\"selected\">". $nr ."</option>";
}
else{
echo "<option>". $nr ."</option>";
}
$nr++;
}
?>
</select>
You can use:
<option value="someValue" selected>Some Value</option>
instead of,
<option value="someValue" selected = "selected">Some Value</option>
both are equally correct.
Set selected="selected" where is option value is 3
please see below example
<option selected="selected" value="3" >3</option>
I myself use it
<select selected=''>
<option value=''></option>
<option value='1'>ccc</option>
<option value='2'>xxx</option>
<option value='3'>zzz</option>
<option value='4'>aaa</option>
<option value='5'>qqq</option>
<option value='6'>wwww</option>
</select>
You just need to put attribute "selected" on a particular option instead direct to select element.
Here is snippet for same and multiple working example with different values.
Select Option 3 :-
<select name="hall" id="hall">
<option>1</option>
<option>2</option>
<option selected="selected">3</option>
<option>4</option>
<option>5</option>
</select>
<br/>
<br/>
<br/>
Select Option 5 :-
<select name="hall" id="hall">
<option>1</option>
<option>2</option>
<option>3</option>
<option>4</option>
<option selected="selected">5</option>
</select>
<br/>
<br/>
<br/>
Select Option 2 :-
<select name="hall" id="hall">
<option>1</option>
<option selected="selected">2</option>
<option>3</option>
<option>4</option>
<option>5</option>
</select>
Default selected value is Option-4
<html:select property="status" value="OPTION_4" styleClass="form-control">
<html:option value="">Select</html:option>
<html:option value="OPTION_1" >Option-1</html:option>
<html:option value="OPTION_2" >Option-2</html:option>
<html:option value="OPTION_3" >Option-3</html:option>
<html:option value="OPTION_4" >Option-4</html:option>
<html:option value="OPTION_5" >Option-5</html:option>
</html:select>
You will need an "id" attribute in each option for this solution to work:
<script>
function select_option (id,value_selected) {
var select;
select = document.getElementById(id);
if (select == null) return 0;
var option;
option = select.options.namedItem(value_selected);
if (option == null) return 0;
option.selected = "selected";
return true;
}
</script>
<select name="hall" id="hall">
<option id="1">1</option>
<option id="2">2</option>
<option id="3">3</option>
<option id="4">4</option>
<option id="5">5</option>
</select>
<script>select_option ("hall","3");</script>
The function first tries to find the <select> with the id, then it will search for the value_selected in the <select> options and if it finds it, it will set the selected attribute returning true. False otherwise
The problem with <select> is, it's sometimes disconnected with the state of what's currently rendered and unless something has changed in the option list, no change value is returned. This can be a problem when trying to select the first option from a list. The following code can get the first-option the first-time selected, but onchange="changeFontSize(this)" by its self would not. There are methods described above using a dummy option to force a user to make a change value to pickup the actual first value, such as starting the list with an empty value. Note: onclick would call the function twice, the following code does not, but solves the first-time problem.
<label>Font Size</label>
<select name="fontSize" id="fontSize" onfocus="changeFontSize(this)" onchange="changeFontSize(this)">
<option value="small">Small</option>
<option value="medium">Medium</option>
<option value="large">Large</option>
<option value="extraLarge">Extra large</option>
</select>
<script>
function changeFontSize(x){
body=document.getElementById('body');
if (x.value=="extraLarge") {
body.style.fontSize="25px";
} else {
body.style.fontSize=x.value;
}
}
</script>
I use Angular and i set the default option by
HTML Template
<select #selectConnection [(ngModel)]="selectedVal" class="form-control col-sm-6 " max-width="100px" title="Select"
data-size="10">
<option >test1</option>
<option >test2</option>
</select>
Script:
sselectedVal:any="test1";
You can try like this
<select name="hall" id="hall">
<option>1</option>
<option>2</option>
<option selected="selected">3</option>
<option>4</option>
<option>5</option>
</select>
To set the default using PHP and JavaScript:
State: <select id="State">
<option value="" selected disabled hidden></option>
<option value="Andhra Pradesh">Andhra Pradesh</option>
<option value="Andaman and Nicobar Islands">Andaman and Nicobar Islands</option>
.
.
<option value="West Bengal">West Bengal</option>
</select>
<?php
if(isset($_GET['State'])){
echo <<<heredoc
<script>
document.getElementById("State").querySelector('option[value="{$_GET['State']}"]').selected = true;
</script>
heredoc;
}
?>
This is simple method to make default option selected.
Can be used for multiple selects on an HTML page.
The method:
Find every select
Read the id and value of that select
Make the option selected
Note:
Every select must have ID to avoid conflict
$(document).ready(function() {
// Loop for every select in page
$('select').each(function(index, id) {
// Get the value
var theValue = $(this).attr('value');
// Get the ID
var theID = $(this).attr('id');
// Make option selected
$('select#' + theID + ' option[value=' + theValue + ']').attr('selected', true);
});
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/2.0.0/jquery.min.js"></script>
<select id="sport" name="sport" class="autoselect" value="golf">
<option value="basket">Basket Ball</option>
<option value="tennis">Tennis</option>
<option value="golf">Golf</option>
<option value="bowling">Bowling</option>
</select>
<hr>
<select id="tools" name="tools" class="autoselect" value="saw">
<option value="hammer">Hammer</option>
<option value="drill">Drill</option>
<option value="screwdriver">Screwdriver</option>
<option value="saw">Saw</option>
<option value="wrench">Wrench</option>
</select>
I was having some troubles with it because I need some way to choose the option dynamically accordingly to the value that I have in the database. The script bellow works like a charm to me:
<?php
//pick the value of database
$selected_sexo = $query['s_sexo'];
?>
<select name="s_sexo" id="s_sexo" required>
<option <?php if($selected_sexo == 'M'){echo("selected");}?> value="M">M</option>
<option <?php if($selected_sexo == 'F'){echo("selected");}?> value="F">F</option>
</select>
