Here is my javascript code, i want to pass current selected value of the option to my js function, in this code i used static number 6.
<select name='project_name' class='required input_field' id='project_name' onchange="sendRequest('GET','getClientName.jsp?ProjectId=6')">
<option value=''>-- Select --</option>
<option value="1">Project 1</option>
<option value="2">Project 2</option>
<option value="3">Project 3</option>
</select>
help me to solve this...
Change the string 'getClientName.jsp?ProjectId=6' to
'getClientName.jsp?ProjectId=' + this.options[this.selectedIndex].value)
or
'getClientName.jsp?ProjectId=' + this.value)
but I think the first one is more browser compatible.
var selectBox = document.getElementById('project_name');
selectBox.addEventListener('change', function() {
sendRequest('GET', 'getClientName.jsp?ProjectId=' + this.value);
});
It will help you to get the selected option value . Try this link http://jsfiddle.net/xyaaa/9/.
<html>
<head>
<script>
function getOption(t){
var val;
var options = t.options;
for(var i=0,len=options.length;i<len;i++){
var option = options[i];
if(option.selected){
val = option.value;
}
}
return val;
}
function sendRequest(method , url){
console.log(url);
}
</script>
</head>
<body>
<select onchange="var x=getOption(this);sendRequest('GET','getClientName.jsp?ProjectId='+x)">
<option value="1">Project 1</option>
<option value="2">Project 2</option>
<option value="3">Project 3</option>
</select>
</body>

Thanks for help!
You shouldn't be swapping the values or the text of the two selected items in the lists. You just need to swap which item is selected in each list. Once that is done, that option will have whatever value the list has set up for it.
The version of JQuery you use here doesn't matter since what you are doing requires JQuery operations that have been in JQuery since the beginning.
var sel1 = $("#se1");
var sel2 = $("#se2");
function swap() {
let selection1 = sel1[0].selectedIndex; // Store the first list's selection
sel1[0].selectedIndex = sel2[0].selectedIndex;
sel2[0].selectedIndex = selection1;
// Test
console.log(sel1.val(), sel2.val());
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script>
<select id="se1">
<option value="1">DOG</option>
<option value="2">CAT</option>
<option value="3">BIRD</option>
</select>
<button onclick="swap()">SWAP</button>
<select id="se2">
<option value="4">DOG</option>
<option value="5">CAT</option>
<option value="6">BIRD</option>
</select>
I am trying that when the Change event is launched in a select with the same class as others, the value is retrieved, and if it is equal to one data then select another of the same select. My problem is in, I do not know how to create the selector. I've tried like this, but it does not work. Welcome all the answers
$(function(){
$(document).on('change','.sel',function(){
var val = parseInt( $(this).val() );
if( val === 2 ){
$(this + 'option[value="3"]').prop('selected',true);
}
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<select class="sel">
<option value="1">Val 1</option>
<option value="2">Val 2</option>
<option value="3">Val 3</option>
</select>
<select class="sel">
<option value="1">Val 1</option>
<option value="2">Val 2</option>
<option value="3">Val 3</option>
</select>
You can use this keyword to get select element and then use find method to get desired option. You cannot use this like you did in your example. Try running this + 'option[value="3"]' in your console - it will output "[object Window]option[value=\"3\"]", which is not a selector you wanted.
$(function(){
$(document).on('change','.sel',function(){
var val = parseInt( $(this).val() );
if( val === 2 ){
$(this).find("option[value='3']").prop('selected',true);
}
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<select class="sel">
<option value="1">Val 1</option>
<option value="2">Val 2</option>
<option value="3">Val 3</option>
</select>
<select class="sel">
<option value="1">Val 1</option>
<option value="2">Val 2</option>
<option value="3">Val 3</option>
</select>
$('.sel > option').click(function(e){
var = trueVal = "";
var selectedVal = $(e.target).attr('value');
if(selectedVal == '1'){
trueVal = '2';
} else if(selectedVal == '2'){
trueVal = '3';
}
return trueVal;
console.log(trueVal);
// Do whatever you want with trueValue
});
i am new to Javascript/ Jquery
so my problem is :
i want to change the select/option box text and value depending on the other selected option/box
so for examplemy first option is :
<select id="gender">
<option>Select Your Gender</option>
<option value="Male">Male</option>
<option value="Female">Female</option>
</select>
and then one i want to change depending on selected option is :
When its male :
<select id="name">
<option>Select Your Name</option>
<option value="Male1">Male 1</option>
<option value="Male2">Male 2</option>
</select>
when its female :
<select id="name">
<option>Select Your Name</option>
<option value="female1">Female 1</option>
<option value="female2">Female 2</option>
</select>
Thanks for the help! :)
There you go with DEMO
var options=""; //store the dynamic options
$("#gender").on('change',function(){ //add a change event handler to gender select
var value=$(this).val(); //get its selected value
options="<option>Select Your Name</option>"
if(value=="Male") //value ==Male then set male required options
{
options+="<option value='Male1'>Male 1</option>"
+"<option value='Male2'>Male 2</option>";
$("#name").html(options);
}
else if(value=="Female") //else set female required options
{
options+='<option value="female1">Female 1</option>'
+'<option value="female2">Female 2</option>';
$("#name").html(options);
}
else
$("#name").find('option').remove() //if first default text option is selected empty the select
});
I would suggest to have a better HTML architecture to achieve this kind of things. Have each name in one Dropdown only and categorise with some data attribute. When changing the value of Gender Dropdown, filter with type and toggle the options. Follow this:
$(function(){
$("#gender").on("change", function(){
var $target = $("#name").val(""),
gender = $(this).val();
$target
.toggleClass("hidden", gender === "")
.find("option:gt(0)").addClass("hidden")
.siblings().filter("[data-type="+gender+"]").removeClass("hidden");
});
});
.hidden{
display:none;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<select id="gender">
<option value="">Select Your Gender</option>
<option value="Male">Male</option>
<option value="Female">Female</option>
</select>
<select id="name" class="hidden">
<option value="">Select Your Name</option>
<option value="Male1" data-type="Male">Male 1</option>
<option value="Male2" data-type="Male">Male 2</option>
<option value="female1" data-type="Female">Female 1</option>
<option value="female2" data-type="Female">Female 2</option>
</select>
Fiddle link: http://jsfiddle.net/ashishanexpert/qzxedcut/
Whenever a change occurs, use the value of the gender dropdown to populate the names one. We use a for loop to produce more than one option per gender.
$('#gender').change(function(){
if(!this.selectedIndex) return;
var gender = $(this).val(),
$name = $('#name').empty(),
$option = $('<option />').text('Select Your Name').appendTo($name);
for(var i = 1; i <= 2; i++)
$option.clone().prop('value', gender + i).text(gender + ' ' + i).appendTo($name);
});
JSFiddle
Follow the Practice:
Do not hardcode options this case.Best practice is get value from Json.
Then later changes are easy instead of change all codings.
Build dynamic Dropdowns. Dont Hide and Show.
HTML
<select id="gender">
<option>Select Your Gender</option>
<option value="Male">Male</option>
<option value="Female">Female</option>
</select>
<select id="gtr" name="location" placeholder="Anycity"></select>
Jquery
jQuery(function($) {
var gender = {
'Male': ['Male1', 'male2'],
'Female': ['Female1','Female1'],
}
var $gndr = $('#gtr');
$('#gender').change(function () { debugger
var GNDR = $(this).val(), gndrs = gender[GNDR] || [];
var html = $.map(gndrs, function(gndr){
return '<option value="' + gndr + '">' + gndr + '</option>'
}).join('');
$gndr.html(html);$gndr.append(new Option("Select Name", "0"));$gndr.val("0");
});
});

I suggest you to try this way:
Change you jquery:
<select id="nameMale">
<option>Select Your Name</option>
<option value="Male1">Male 1</option>
<option value="Male2">Male 2</option>
</select>
<select id="nameFemale">
<option>Select Your Name</option>
<option value="Male1">Male 1</option>
<option value="Male2">Male 2</option>
</select>
Inser this javascript:
<script>
<![CDATA[
$(function() {
$('#nameFemale').hide();
$('#nameMale').hide();
function changeGen(val){
if(val == 'Female'){
$('#nameFemale').show();
$('#nameMale').hide();
}else{
$('#nameFemale').hide();
$('#nameMale').show();
}
}
$('#gender').change(function() {
changeGen($('#gender').val());
});
});
]]>
</script>
FIDDLE
$('#gender').change(function (e) {
var val = $("option:selected", this).val()
console.log(val);
if(val =='Male'){
$('#name').find('option.female').hide();
$('#name').find('option.male').show();
}else if(val =='Female'){
$('#name').find('option.female').show();
$('#name').find('option.male').hide();
}else{
}
});
Added class for each option since it is static.
Then you can hide the option from second select depending on the value of first select
Try this:
$("#gender").on("change",function(){
var sel="";
if($(this).val() == "Female"){
sel=' <option>Select Your Name</option>';
sel+=' <option value="female1">Female 1</option>'
sel+='<option value="female2">Female 2</option>'
}else{// no other if since you have only two options male/female
sel= '<option>Select Your Name</option>';
sel+= '<option value="Male1">Male 1</option>';
sel+= '<option value="Male2">Male 2</option>';
}
$("#name").html(sel);
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<select id="gender">
<option>Select Your Gender</option>
<option value="Male">Male</option>
<option value="Female">Female</option>
</select>
<select id="name">
</select>
function Myfunc(obj1)
{
alert(obj1.prop('outerHTML'));
}
<select id="myselect" onchange="MyFunc(jQuery(this))">
<option value="v1">Value 1</option>
<option value="v2">Value 2</option>
<option value="v3" selected="selected">Value 3</option>
</select>
I have the above two snippets.
When i do alert of the object i get the complete <select&tg; tag along with all it's options.
But, What i want is the object passed should only just be the option which i have selected and not the complete select element block.
Instead of outdated onchange you can use jQuery $('selector').change(function() { });
Fiddle.
Simplified HTML:
<select id="myselect">
<option value="v1">Value 1</option>
<option value="v2">Value 2</option>
<option value="v3" selected="selected">Value 3</option>
</select>
JS:
$(document).ready(function()
{
$('#myselect').change(function()
{
alert($(this).find(':selected').text());
});
});
Update. If you need selected <option> outer HTML, then it can be:
Fiddle.
$(document).ready(function()
{
$('#myselect').change(function()
{
alert($(this).find(':selected')[0].outerHTML);
});
});
Try:
onchange="MyFunc(jQuery(this).find('option:selected'))"
Use as
function MyFunc(obj1)
{
alert($("#myselect option:selected").text());
}
DEMO
OR You can use
function MyFunc(obj1)
{
alert($("#myselect option:selected").html());
}
DEMO
You can pass object or you can fetch selected option in function.
To get selected option html in function use below code -
NOTE - please correct spelling of function either in onchange or function declaration.
function MyFunc(obj1)
{
var value = obj1.value;
var optionHTML = $(obj1).find('option[value="'+value+'"]');
alert($('<div>').append(optionHTML.clone()).html());
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<select id="myselect" onchange="MyFunc(this)">
<option value="v1">Value 1</option>
<option value="v2">Value 2</option>
<option value="v3" selected="selected">Value 3</option>
</select>
Another way is to bind change event handler using jquery and get the option html
$('#myselect').change(function(){
var value = $(this).val();
var option = $(this).find('option[value="'+value+'"]');
var optionHTML = $('<div>').append(option.clone()).html();
alert(optionHTML);
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js">
</script>
<select id="myselect">
<option value="v1">Value 1</option>
<option value="v2">Value 2</option>
<option value="v3" selected="selected">Value 3</option>
</select>
You can use :selected selector follows:
$(document).ready(function() {
$('#myselect').on('change', function() {
alert($(this).find('option:selected').eq(0));
});
});
how to get value from option
<script>
function usgsChanged(el) {
window["display_" + el.options[el.selectedIndex].value]();
}
function display_1() {
//how to get value from option
}
</script>
how to get value from option when select
<select onchange="usgsChanged(this);">
<option value="1">1</option>
<option value="2">2</option>
<option value="">more</option>
<option value="">more</option>
<option value="">more</option>
</select>
<script>
function usgsChanged(option) {
var value = option.value; //The value now resides in this variable
}
</script>
<select onchange="usgsChanged(this);">
<option value="1">1</option>
<option value="2">2</option>
<option value="">more</option>
<option value="">more</option>
<option value="">more</option>
</select>
try something like this
$('#idOfSelectTag').change(function(){
var value = $(this).val();
alert(value);
});
Try looking at internet before sanding a question. For example here.
Try this:
<script type="text/javascript">
function usgsChanged(el) {
var index = el.selectedIndex;
var selectOptions = el.options;
var optionValue = selectOptions[index].value;
var optionText = selectOptions[index].text;
alert("Value is " + optionValue + " and text is " + optionText );
}
</script>
And HTML:
<select onchange="usgsChanged(this)">
<option value="1">1</option>
<option value="2">2</option>
<option value="">more</option>
<option value="">more</option>
<option value="">more</option>
</select>
