I have a HTML file with a simple drop down list.
Upon selecting one of the choices, I want the choice to be stored in a hidden input.
<div id ="mainContent">
<span style="font-size: 15px;"> Category : </span> <select id="selectid" name="filecategory">
<option value="A">A</option>
<option value="B">B</option>
<option value="C">C</option>
<option value="D">D</option>
<option value="E">E</option>
</select>
<br /><br />
<input type="hidden" name="filecategory" value="XXX" />
</div>
I did some research online and came up with this handler code upon detecting a change event in the drop down list.
$("#selectid").change(function(){
alert('change called');
});
Can someone tell me how I can set the hidden input via this handler ?
Solved here:
$("#selectid").change(function(){
$("input[name='filecategory']").val($(this).val())
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<select id="selectid" name="filecategory">
<option value="A">A</option>
<option value="B">B</option>
<option value="C">C</option>
<option value="D">D</option>
<option value="E">E</option>
</select>
<input type="hidden" name="filecategory" value="XXX" />

I am writing a webpage in which a user will see a menu with a default text shown (in this case "choose baseline"). After they select one of the options, I need to have a button that can reset the select menu to its 'Choose baseline' default. How can I do this?
<select onchange="saveSelection(value)">
<option value="" selected disabled hidden>Choose Baseline</option>
<option value="A">A</option>
<option value="B">B</option>
<option value="C">C</option>
</select>
<button type="button">Reset menu</button>
You can add an id on your select. Then add a function clearSelection to be triggered on click of the button.
function saveSelection(value) {
}
function clearSelection() {
//This will select the first option of the select
document.getElementById('select-baseline').options[0].selected = 'selected';
}
<select id='select-baseline' onchange="saveSelection(value)">
<option value="" selected disabled hidden>Choose Baseline</option>
<option value="A">A</option>
<option value="B">B</option>
<option value="C">C</option>
</select>
<button type="button" onClick="clearSelection()">Reset menu</button>
Put all this code inside the form tag. This will allow you to apply the clear functionality to the select tag and change your button type to reset
<form>
<select>
...
</select>
<button type="reset">Reset Menu</button>
</form>
<select id="menu" onchange="saveSelection(value)">
<option value="" selected disabled hidden>Choose Baseline</option>
<option value="A">A</option>
<option value="B">B</option>
<option value="C">C</option>
</select>
<button type="button" onclick="resetMenu()">Reset menu</button>
<script src="test.js"></script>
JavaScript
function resetMenu() {
var element = document.getElementById('menu');
element.value = '';
}
I want to link categories to their own pages. so I mean when I click to 'Hotels' it should open the page which is Category/Hotels
this is the current code
<select name="category">
<option value="">Any Category</option>
<option value="clubs">Clubs</option></a>
<option value="hotels">Hotels</option>
<option value="pubbar">Pub&Bar</option>
<option value="restaurants">Restaurants</option>
</select>
lets say I want to link like that
<option value="www.website.com/event_cat/clubs/> Clubs </option>
<option value="www.website.com/event_cat/hotels/> Hotels </option>
.. and so on
but when I do, its directing to this page:
www.website.com/events/?time=&category=%2Fevent_cat%2Fclubs%2F&location=
JSfiddle Demo
<html>
<body>
<form name="blah_blah">
<select name="ddmenu_name" id="ddmenu_name" style="width: 80% !important;">
<option value="" selected>Select Site</option>
<option value="http://www.yahoo.com">Yahoo!!!</option>
<option value="http://www.gmail.com">Gmail</option>
<option value="http://www.google.co.in">Google</option>
<option value="http://www.facebook.com">Facebook</option>
</select>
<input type="button" name="Submit" value="Go!" onClick="window.open(ddmenu_name.value,'newtab'+ddmenu_name.value)">
</form>
</body>
</html>
You just have to use full domain path with http or https(if its a secure server)
<option value="http://www.website.com/event_cat/clubs/> Clubs </option>
<option value="http://www.website.com/event_cat/hotels/> Hotels </option>
Since you have the first option already selected, in the first option, keep the value empty and add the onchange, as per the code below:
<select onchange="this.options[this.selectedIndex].value && (window.location = this.options[this.selectedIndex].value);">
<option value="">Any Category</option>
<option value="www.website.com/event_cat/clubs/">Clubs</option>
<option value="www.website.com/event_cat/hotels/">Hotels</option>
<option value="pubbar">Pub&Bar</option>
<option value="restaurants">Restaurants</option>
</select>
Exists a method for click in label and select one specific option into select?
I don't like use JS

<option value="">teste X</option>
<option value="" id="a">teste A</option>
</select>
Thanks!
html:
<label data-value="c">C</label>
<select name="" id="myselect">
<option value="a">A</option>
<option value="b">B</option>
<option value="c">C</option>
</select>
jQuery:
$(document).on("click", "label", function(evt) {
evt.preventDefault();
$("#myselect").val($(this).data("value"));
});
I have a form that is like the following:
<label>
scale a<input type="radio" name="sellorbuy" value="Yes" id="rdYes" />
</label>
<label class="leftspace">
scale b<input type="radio" name="sellorbuy" value="No" id="rdNo" />
</label>
<p class="searchpg">Price</p>
<fieldset id="sell">
<select id="pricemin" name="minsell" class="form-control">
<option value="50000">Min Price</option>
<option value="100000">£100,000</option>
<option value="200000" >£200,000</option>
<option value="300000" >£300,000</option>
<option value="400000" >£400,000</option>
</select>
<select id="pricemax" name="maxsell" class="form-control">
<option value="5000000">Max Price</option>
<option value="100000">£100,000</option>
<option value="200000">£200,000</option>
<option value="300000">£300,000</option>
<option value="400000">£400,000</option>
<option value="500000">£500,000</option>
</select>
</fieldset>
<fieldset id="let" style="display:none;">
<select id="lpricemin" name="minbuy" class="form-control">
<option value="500">Min Price</option>
<option value="500">£500</option>
<option value="600">£600</option>
<option value="700">£700</option>
<option value="800">£800</option>
<option value="900">£900</option>
</select>
<select id="lpricemax" name="maxbuy" class="form-control">
<option value="5000">Max Price</option>
<option value="600">£600</option>
<option value="700">£700</option>
<option value="800">£800</option>
<option value="900">£900</option>
<option value="1000">£1000</option>
<option value="1150">£1150</option>
</select>
</fieldset>
This switches fieldsets by using the following:
$("input[name='sellorlet']").change(function () {
$("#sell").toggle(this.value == "Yes");
$("#let").toggle(this.value == "No");
});
The trouble I am having is the search form that is submitted and displayed on the next page so we carry over the contents of the form. If someone has selected the 'Scale B' then that is already toggled on the next page but the fieldset has not changed? Is there any way to change to the jquery to detect which checkbox is toggled and change the fieldset accordingly or even modify the switch to make it work better?
Created a fiddle to show how the form works https://jsfiddle.net/v3waaa20/1/
Some slight changes and triggering change on load can do the trick.
$("input[name='sellorbuy']").change(function () {
value = $("input[name='sellorbuy']:checked").val();
$("#sell").toggle(value == "Yes");
$("#let").toggle(value == "No");
}).change();
i have an old classic asp application that need to update. i need to add 2 dropdowns and the second one needs to be populated based on the first (ex. country and states). how do you do that using javascript?
UPDATE: Based on your comment below, I've updated my response to include code that will do what you're wanting. You can use the optgroup element to filter options based on what country is selected without having to use Ajax.
First way: (optgroup filtering)
Working example on jsFiddle.
HTML:
<select id="C_Country" name="C_Country" aria-required="true" class="required">
<option value="">-- Please Select --</option>
<option value="USA">United States</option>
<option value="CA">Canada</option>
</select>
<p>
<label for="C_State_Prov">State or Province <span title="required">*</span>
</label>
</p>
<select id="C_State_Prov" name="C_State_Prov" aria-required="true" class="required">
<option value="" selected="">-- Please Select --</option>
<optgroup label="United States">
<option value="AK">Alaska</option>
<option value="AL">Alabama</option>
<option value="AR">Arkansas</option>
<option value="AZ">Arizona</option>
<option value="CA">California</option>
</optgroup>
<optgroup label="Canada">
<option value="AB">Alberta</option>
<option value="BC">British Columbia</option>
<option value="MB">Manitoba</option>
</optgroup>
</select>
JavaScript:
var state_province = $('#C_State_Prov option, #C_State_Prov optgroup');
state_province.hide();
$('#C_Country').change(function () {
state_province.hide();
$("#C_State_Prov optgroup[label='" + $(this).find(':selected').html() + "']")
.children()
.andSelf()
.show();
});
Second way: (Ajax)
Working example on jsFiddle.
Here's a rough idea of how to accomplish this. The URL defined in the jQuery should point to a location where the server-side code will generate the HTML needed based on the country the user selected (instead of being defined as a variable in the JavaScript).
HTML:
<form action="#">
<div>
<label for="country">Country:</label>
</div>
<div>
<select name="country" id="country">
<option value="">Please select</option>
<option value="us">United States</option>
</select>
</div>
<div id="stateContainer" class="hidden">
<div>
<label for="state">State</label>
</div>
<div>
<select id="state" name="state"></select>
</div>
</div>
<div>
<input type="submit" id="submit" name="submit" value="Submit">
</div>
</form>
CSS:
.hidden {
display: none;
}
JavaScript:
var $country = $("#country"),
$stateContainer = $("#stateContainer"),
$state = $("#state"),
url = "http://jsfiddle.net/htmled/KZ4jd/",
html = '<option value="al">Alabama</option><option value="ar">Arkansas</option>',
countryVal;
$country.change(function () {
countryVal = $country.val();
$stateContainer.show();
$state.html(html).load(loadUrl);
});
