I have a javascript script that looks for the value and of dropdown and changes the next dropdown menu based on what the value is, however this will no longer work for me as i need to pass the value back to ruby so i can save it in sessions.
$(document).ready(function() {
$('#Exposures').bind('change', function() {
var elements = $('div.exposures').children().hide(); // hide all the elements
var value = $(this).val();
if (value.length) { // if something is selected
elements.filter('.' + value).show(); // show the ones we want
}
}).trigger('change');
$('.second-level-select').bind('change', function() {
var elements = $('div.second-level-container').children().hide(); // hide all the elements
var value = $(this).val();
if (value.length) { // if something is selected
elements.filter('.' + value).show(); // show the ones we want
}
}).trigger('change');
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.0.0/jquery.min.js"></script>
<select class="pmmargin3 exp" size="1" id="Exposures" title="" name="exposures_pt1">

Thank you for any help, I'm fairly new to Javascript and am trying my best but still need some guidance.
As per what I understood. You want to send data selected in first dropdown to ruby to save it in Session.
If that is the case, on every select you can trigger AJAX call with cookies and update the session object accordingly and also subsequently display it in second dropdown as well.
Though, onChange AJAX is not a really good suggestion, in that scenario you can save selected option into browser sessionStorage and later add it to session object by a single ajax to your server at the end of your selection(dropdown) cycle.
Well i figured out how to get my results back and keep the value the same in my code so nothing else breaks here is how i did it.
$(document).ready(function() {
$('#Exposures').bind('change', function() {
var elements = $('div.exposures').children().hide(); // hide all the elements
var value = $(this).val();
*added* var exposuredd = document.getElementById("Exposures");
*added* var selectedText = exposuredd.options[exposuredd.selectedIndex].text;
*added* document.getElementById("exp1").innerHTML="<input type='text' name='exposures_pt1' value='"+selectedText+"' >";
if (value.length) { // if somethings' selected
elements.filter('.' + value).show(); // show the ones we want
}
}).trigger('change');
$('.second-level-select').bind('change', function() {
var elements = $('div.second-level-container').children().hide(); // hide all the elements
var value = $(this).val();
if (value.length) { // if somethings' selected
elements.filter('.' + value).show(); // show the ones we want
}
}).trigger('change');
});
this needs to be in the erb im using this in
<p hidden id="exp1"></p>
So now i can pass whatever text is in my options to ruby such as...."Hey Here I am"
<option value="1">Hey Here I am</option>

I have a select box that contains certain elements (see below):
<select id="test" name="test">
<option value="12345">12345 - Test</option>
<option value="67890">67890 - Test 2</option>
<option value="53453">53453 - Test 3</option>
</select>
Here is what I'm trying to accomplish When the user selects a certain element, I want certain elements of the text to hide. For example, if I select 12345, I want the - Test to hide.
How can I do it in jQuery?
Thank you,
Kevin
A brute force-y way to do it would be to keep track of the internal text and values of the currently-selected option, then replace the text with the desired text when the option changes. This part's easy in your case, since the desired output text is the same as the option's value.
I opted to add a blank option at the beginning, since by default the text will not have changed, but you can get around this by adding a trigger to go off when the page is finished loading.
var selectedTextOrig = "";
var selectedValue = 0;
$("#test").change(function() {
// Reset the inner html text for the previously-selected option
$("#test option").each(function() {
if ($(this).val() == selectedValue) {
$(this).text(selectedTextOrig);
return false; // break out of $.each()
}
});
// Store the viewable text and value of the currently selected
selectedValue = $("#test option:selected").val();
selectedTextOrig = $("#test option:selected").text();
// Replace the current inner html
$("#test option:selected").text(selectedValue);
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<select id="test" name="test">
<option disabled="disabled" selected></option>
<option value="12345">12345 - Test</option>
<option value="67890">67890 - Test 2</option>
<option value="53453">53453 - Test 3</option>
</select>
I have found a solution:
Here is how I achieved it:
$('select[name="test"]').find('option').remove().end();
$('select[name="test"]').append(new Option(selectId, selectId));
$('select[name="test"]').trigger('change');
I have created a dropdown box with 3 options on my website.
I want to change some text on the webpage, depending on the drop-down item selected. For example:
If dropdown option 1 is chosen, I would like some text on the page that says "You have chosen option 1".
I don't know any JavaScript and so I haven't tried anything apart from trying to search for a similar solution.
<select name="os0" style="background: #315d80; color: #fff; border-color: white; border: 0px;">
<option value="op1">Option 1</option>
<option value="op2">Option 2</option>
<option value="op3">Option 3</option>
</select>
Full sultion with jQuery (I started typing it before you added the HTML to your question so the options are italian car brands).
https://jsfiddle.net/mL2c2xb6/
HTML:
<select id="carSelect">
<option></option>
<option value="Audi">Audi</option>
<option value="Ferrari">Ferrari</option>
<option value="Fiat">Fiat</option>
</select>
<p id="choiceDisplay">
Selection Display
</p>
Javascript:
$('select').change(function(){ // Listen to changes to <select> element
const options = $("option"); // Get all the <option> elements.
let selectedOption = ""; // Var to store selected option value.
options.each(function(index){ // Iterate through option elements.
let option = options[index];
if($(option).prop("selected")) { // Find the seletced one.
selectedOption = $(option).val(); // Get the value and store it
};
});
$("#choiceDisplay")
.empty()
.append(selectedOption); // Display the result.
});
var e = document.querySelector('[name="os0"]');
var strUser = "";
e.addEventListener("change", function(){
strUser = e.options[e.selectedIndex].innerHTML;
alert("You have chosen " + strUser);
});
I have a select box and add more button. when I click add more button it's creating another select using clone.In first select box I select one option value from select box means that value should be removed from next created select box.At the same time which selected value in select box that current value shown on current select box. Select box value is being loaded dynamically.
Eg:
<select name="section" id="section_1" class="sectionType">
<option value=" ">------</option>
<option value="05">test1</option>
<option value="06">test2</option>
<option value="07">test3</option>
<option value="08">test4</option>
<option value="10">test5</option>
<option value="11">test6</option>
<option value="12">test7</option>
<option value="13">test8</option>
<option value="14">test9</option>
</select>
Is it what you're looking for ?
I would recommend you to play and manipulate with index(), that won't bother your dynamic values.
//Take a clone of last
var cloneElement = $('.sectionType:last').clone();
//Get index of option selected from last
var indexToRemove = $('.sectionType:last').find('option:selected').index();
//Remove previously selected index
cloneElement.find('option').eq(indexToRemove).remove();
//Change the id of an element
cloneElement.attr("id", "section_"+parseInt($('.sectionType').length+1));
//If element has options
if(cloneElement.find('option').length)
{
//Finally append it
$('body').append("<br/><br/>").append(cloneElement);
}
$('button').click(function(){
//Take a clone of last
var cloneElement = $('.sectionType:last').clone();
//Get index of option selected from last
var indexToRemove = $('.sectionType:last').find('option:selected').index();
//Remove previously selected index
cloneElement.find('option').eq(indexToRemove).remove();
//Change the id of an element
cloneElement.attr("id", "section_"+parseInt($('.sectionType').length+1));
//If element has options
if(cloneElement.find('option').length)
{
//Finally append it
$('body').append("<br/><br/>").append(cloneElement);
}
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<select name="section" id="section_1" class="sectionType">
<option value="">------</option>
<option value="05">test1</option>
<option value="06">test2</option>
<option value="07">test3</option>
<option value="08">test4</option>
<option value="10">test5</option>
<option value="11">test6</option>
<option value="12">test7</option>
<option value="13">test8</option>
<option value="14">test9</option>
</select>
<button>Clone</button>
You can try like this.
$("#yourId").val(" ")//if your value has white spec else use like below line
$("#YourId").val("")//What ever you want to be selected, place your value in .val()
I hope this will help you, if you need anything please ask!
$("button").on("click", function() {
$("#section_1")
.clone()
.attr("id", "section_2")
.on("change", function() {
var sec2Val = $(this).val();
var delOption = $("#section_1 > option[value=" + sec2Val + "]").detach();
optionHolder.push(delOption);
})
.insertAfter($("#section_1"));
$(this).attr("disabled", "disabled");
});
var optionHolder = [];
$("#section_1").on("change", function() {
var sec1Val = $(this).val();
if ($("#section_2")) {
var delOption = $("#section_2 > option[value=" + sec1Val + "]").detach();

i have this form ..
<form method="post" action=''>
<select class="first">
<option value="0">choose ...</option>
<option value="1">Hello</option>
<option value="3">It's</option>
</select>
<select class="second">
<option value="0">choose ...</option>
<option value="2">World</option>
<option value="4">me</option>
</select>
<input type="text" class="dest" value="" />
</form>
and would like to dynamically gather selected informations with jQuery, because I need to decide on the selected values ...
When you select specific combination of OPTION values (lets say Hello + World) it should add some value to INPUT.dest and lock it (disable from editing) ...
But I can't make it work ... What I have, is that on each change of each select (separately only) i can map the actual value
$(document).ready(function () {
$(".first").change(function () {
var option = $(this).find("option:selected").val();
$(".dest").val(option);
});
$(".second").change(function () {
var option2 = $(this).find("option:selected").val();
$(".dest").val(option2);
});
});
Here is the live demo in fiddle
Do you know what am I missing? I know it will be just a little thing .. thank you
I would generalize it and use one event listener, and then gather the combination and do whatever:
$("select").change(function () {
var first = $(".first").find("option:selected").val();
var second = $(".second").find("option:selected").val();
if(first == 1 && second == 2)
$(".dest").val("Hello world").prop("disabled",true);
else
$(".dest").val("Something else").prop("disabled",false);
});

I have two dynamically populated selectboxes with data coming from same json object within the page. What I want to achieve is to link the two boxes so that whenever there is a change in one select box the same option in other select box gets automatically disabled.
So suppose Xiomi and the corresponding second value Xiomi Redme is selected in first selectboxes then the same option Xiomi Redme should not be available for selection in the other select box
<div>
<select id="brand-select" name="Brand">
<option value=''>Select Brand</option>
<option value='300'>Xiomi</option>
<option value='147'>HTC</option>
</select>
</div>
<div>
<select id='mobile_model_select' name='Mobile_Brand_Models' style='width:208px;'></select>
</div>
<div>
<select id="brand-select_product2" name="Brand">
<option value=''>Select Brand</option>
<option value='300'>Xiomi</option>
<option value='147'>HTC</option>
</select>
</div>
<div>
<select id='mobile_model_select_product2' name='Mobile_Brand_Models_For_Product2' style='width:208px;'></select>
</div>
Here is my jquery code
$(document).ready(function(){
var modelData = {
"300":{
"MI3_16GB":"XIAOMI Mi3 (16GB)",
"REDMI_NOTE":"XIAOMI REDMI NOTE",
"REDMI":"XIAOMI Redmi ",
"REDMI_1S":"XIAOMI REDMI 1S"
},
"147":{
"ONE_M8":"HTC One (M8)",
"DESIRE_610":"HTC Desire 610",
"ONE_E8":"HTC ONE E8"
}
};
$('#brand_select').change(function(){
correspondingId = $(this).find(":selected").val();
var correspondingIdObject = modelData[correspondingId];
$('#mobile_model_select option').remove();
$.each(correspondingIdObject, function(key, value){
$('#mobile_model_select').append($("<option>").text(value).attr('value',key));
});
$('#brand_select_product2').change(function(){ //
correspondingSelectedIdObject = $(this).find(":selected").val();
$('#mobile_model_select_product2 option').remove();
$.each(correspondingSelectedIdObject, function(key, value){
$('#mobile_model_select_product2').append($("<option>").text(value).attr('value',key));
});
});
My problem is how to link the two onchange functions so that whenever the value is changed in one the same option in the other select box is disabled.
for (var i=0; i<selects.length; i++) {
$(selects[i]).find('option').removeAttr('disabled');
for (var j=0; j<vals.length; j++) {
$(selects[i]).find('option[value='+vals[j]+']').attr('disabled', 'disabled');
}
}
have a look at this fiddle .. hope this helps u ...
