I have two dropdown lists of states . In both dropdown items there is two state Alaska and California. If I select any item from dropdown list one then I hit the radio button so the other dropdown must have same selection. Can anyone help me please? Thanks
<form>
<select id="state1" name="state1">
<option value="Alaska">Alaska</option>
<option value="California">California</option>
</select>
<select id="state2" name="state2">
<option value="Alaska">Alaska</option>
<option value="California">California</option>
</select>
<input type="radio" id="yes" name="yesNo" onclick="yesnoCheck()" value="yes" />
</form>
JavaScript Code
<script>
var state= document.getElementById("state");
var selectedText = state.options[state.selectedIndex].text;
var state1= document.getElementById("state1");
var selectedText1 = state.options[state.selectedIndex].text;
selectedText1 =selectedText;
</script>
You can simply do this by assigning the value of the first select to the second when the radio button is clicked.
var stateSelect1 = document.getElementById("state1");
var stateOption1 = document.getElementById("yes");
var stateSelect2 = document.getElementById("state2");
stateOption1.onclick = function(){
stateSelect2.value = stateSelect1.value
}
<form>
<select id="state1" name="state1">
<option value="Alaska">Alaska</option>
<option value="California">California</option>
</select>
<select id="state2" name="state2">
<option value="Alaska">Alaska</option>
<option value="California">California</option>
</select>
<input type="radio" id="yes" name="yesNo" value="yes" />
</form>
If you check the box the value will be set to the value in the first select.
In your backend you have to change yes or no to true or false.
<form>
<select id="state1" name="state1">
<option value="Alaska">Alaska</option>
<option value="California">California</option>
</select>
<select id="state2" name="state2">
<option id="state2_Alaska" value="Alaska">Alaska</option>
<option id="state2_California" value="California">California</option>
</select>
<input id="radioCheck" type="checkbox" name="yesNo" />
</form>
<script>
document.querySelector("#radioCheck").addEventListener("change", function() {
if(document.querySelector("#radioCheck").value == true){
var state = document.querySelector("#state1").value;
document.querySelector("#state2_" + state).setAttribute("selected", true);
}
});
</script>

I have 4 choice fields in a single form. My jQuery code only captures one field. How can I capture the other fields and extract their values?
Also, I have applied the Select2 plugin on all these fields. Can someone please guide me? Thanks in advance.
$('select').change(function() {
var optionSelected = $(this).find("option:selected");
var valueSelected = optionSelected.val();
var textSelected = optionSelected.text();
var csr = $("input[name=csrfmiddlewaretoken]").val();
console.log(textSelected);
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.4.0/jquery.min.js"></script>
<label for="id_package_form-patient">Patient:</label>
<select name="package_form-patient" required id="id_package_form-patient">
<option value="" selected>---------</option>
<option value="8">jfkdfkldlfd</option>
</select>
<label for="id_package_form-diagnosis">Diagnosis:</label>
<select name="package_form-diagnosis" required id="id_package_form-diagnosis">
<option value="" selected>---------</option>
<option value="1">fefafd</option>
<option value="2">effeafaefe</option>

<label for="id_package_form-treatment">Treatment:</label>
<select name="package_form-treatment" required id="id_package_form-treatment">

</select>
To get the selected text of all the select elements you can use map() to build an array of them, like this:
let getSelectedText = () => {
let textArr = $selects.map((i, el) => $(el).find('option:selected').text()).get();
console.log(textArr);
}
let $selects = $('select').on('change', getSelectedText);

I have many filter button like below, how can I get the select value without using its id?
<select name="selectId" id="selectId" multiple
class="selectpicker required form-control" data-live-search="true">
<option value="All" selected>All</option>
<option value="1" selected>1</option>
<option value="2" selected>2</option>
</select>
<select name="selectStore" id="selectStore" multiple
class="selectpicker required form-control" data-live-search="true">
<option value="All" selected>All</option>
<option value="A" selected>Store A</option>
<option value="B" selected>Store B</option>
</select>
<select name="selectProduct" id="selectProduct" multiple
class="selectpicker required form-control" data-live-search="true">
<option value="All" selected>All</option>
<option value="apple" selected>Apple</option>
<option value="orange" selected>Orange</option>
</select>
Normally, I will use this code to find the changed select button:
$(document).ready(function() {
// Get filter function for chart
$('#selectId').change(function() {
var select = $("#selectId").val();
if (selectLength >= 1 && select.includes("All")) {
$('.selectpicker#selectId').selectpicker('deselectAll');
makeChart();
}
else {
makeChartFilter(select);
}
})
});
But the problem is when there are many filter buttons, I have to write many functions like above and just only change the id.
How can I just use something like this:
$(document).ready(function() {
// Get filter function for chart
$('#selectpicker').change(function() {
id_change = something;
var select = $("#id_change").val();
...
})
});
Using vanilla JavaScript and the eventTarget, this is relatively straight forward. Here is an example:
document.getElementById('container').onchange = ({ target }) => {
console.log(target.value);
};
<form id="container">
<select name="foo">
<option>1</option>
<option>2</option>
<option>3</option>
</select>
<select name="bar">
<option>a</option>
<option>b</option>
<option>c</option>
</select>
</form>
I have 2 select boxes where first is all user selectable but in second selected option is dependant on first select box. Selected value in first option box matches option's class in second select box but values are different. I imagine i need something like:
$('#territory').change(function() {
if($(this).val() == 'EU')
{
$('#territory2').class('EU');
}
How do i select selected option by class name? (There might be more than 1 option with the same class name but it just needs to select any of them).
<select id="territory" name="territory"">
<option value="EU">A</option>
<option value="GB">B</option>
<option value="ALL">C</option>
</select>
<select id="territory2" name="territory2">
<option value="1" class="EU">A</option>
<option value="2" class="GB">B</option>
<option value="3" class="ALL">C</option>
<option value="4" class="ALL">D</option>
</select>
Set the value attribute of the desired <option> element on the value attribute of the <select>:
const territory = document.getElementById("territory"),
territory2 = document.getElementById("territory2");
territory.addEventListener("input", ev => {
territory2.querySelector("."+territory.value).selected = true;
});
<select id="territory" name="territory">
<option value="EU">A</option>
<option value="GB">B</option>
<option value="ALL">C</option>
</select>
<select id="territory2" name="territory2">
<option value="1" class="EU">A</option>
<option value="2" class="GB">B</option>
<option value="3" class="ALL">C</option>
<option value="4" class="ALL">D</option>
</select>
Note that this will only select the first option with that class.
I recommend data-attribute:
$('#territory').on("change", function() {
const territory = $("option:selected", this).data("territory");
$("#territory2").val(territory)
})
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<select id="territory" name="territory">
<option value="" data-territory="0">Please select</option>
<option value="EU" data-territory="1">A</option>
<option value="GB" data-territory="2">B</option>
<option value="ALL" data-territory="3">C</option>
</select>
<select id="territory2" name="territory2">
<option value="0">Please select</option>
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
</select>
I was wondering why why I select 2 with a select tag it returns true in the console. But Whenever I select 2 in the datalist it returns false in the console.
In short I need the datalist to return tru. I need to it be true so that when the user enters in the input I can ensure that the user has enter in a option I wanted (one of the drop down menu options )
function castvote() {
var selected = document.getElementById('vote');
console.log("Chrome" in selected);
}
<input list="vote" onchange="castvote()" id="voteInput">
<datalist id="vote" >
<option value="Chrome">
</datalist>
<label>Choose a browser from this list:
<input id = "a" list="browsers" name="myBrowser"
style="width: 400px;" onclick="test()" /></label>
<datalist id="browsers">
<option value="Chrome">
<option value="Firefox">
<option value="Internet Explorer">
<option value="Opera">
<option value="Safari">
<option value="Microsoft Edge">
</datalist>
You should try this.
I just put (.children) at the getElementById() to get all children of datalist and the onChange() function put at the input tag.
<input list="vote" onchange="castvote()" id="voteInput">
<datalist id="vote" >
<option value="2">
<option value="3">
<option value="4">
<option value="5">
<option value="6">
</datalist>
<script>
function castvote() {
var datalist = document.getElementById('vote').children;
console.log("2" in datalist);
}
</script>
I need help on something really simple.
I have 2 dropdown boxes on a form:
<select name="OfficeLocation" >
<option value="" ></option>
<option value="1" selected="selected">New York</option>
<option value="2" >Los Angeles</option>
<option value="3" >San Francisco</option>
</select>
<select name="OfficePhone">
<option value="" ></option>
<option value="1">(718)555-1212</option>
<option value="2" >(213)555-1212</option>
<option value="3" >(415)555-1214</option>
</select>
The second one is "Read Only"
All I need to know is how can I change the value of "OfficePhone" by changing the value of "OfficeLocation"? using either a simple JavaScript or JSP Command
Thanks
You are able to use a script like the following:
<script>
menu1 = document.getElementsByName('OfficeLocation')[0];
menu2 = document.getElementsByName('OfficePhone')[0];
menu1.onchange = function(){
menu2.value = menu1.value;
}
</script>
Here you are using the onchange event to initiate a function that make the value on the second menu menu2 equals to the selected value of the first menu menu1.
An online demo is here
Notice that: the script should be placed after your elements.
You gonna need an event handler function for the OfficeLocation select and an id for the second select.
<select name="OfficeLocation" onchange="eHandler">
<option value="" ></option>
<option value="1" selected="selected">New York</option>
<option value="2" >Los Angeles</option>
<option value="3" >San Francisco</option>
</select>
<select name="OfficePhone" id="oPhone">
<option value="" ></option>
<option value="1">(718)555-1212</option>
<option value="2" >(213)555-1212</option>
<option value="3" >(415)555-1214</option>
</select>
You have to implement your event handler in your script, like this:
function eHandler(){
var secondSelect = document.getElementById('oPhone');
secondSelect.value = //the value you want to be selected
}
