I have something like this:
<select class="bla">
<option value="1">...</option>
<option value="2">...</option>
</select>
<select class="bla">
<option value="1">...</option>
<option value="2">...</option>
</select>
<select class="bla">
<option value="1">...</option>
<option value="2">...</option>
</select>
<input class="alloptions" type="hidden" value="">
I want the hidden input field value to change every time a different option is selected in each of the select input fields above.
This value would contain the selected options from all input fields separated with commas.
How can I do this?
Something like:
$('select.bla').change(function() {
$value = $('select.bla').map(function(){return $(this).val()}).get().join(',');
$('input.alloptions').val($value);
});
Explanation:
change() gets fired whenever the value of a select field changes
With map() we create an array of the values of the select fields and join them to a string separated by commas
change event is what you are after.
The .serialize() method can act on a jQuery object that has selected individual form elements, such as "input", "textarea", and "select" - meaning you could do the following:
$('.bla').change(function(){
var opts = $('select').serialize();
$('.alloptions').val(opts);
});
Each "select" would need a name value and would produce:
selec1=1&select2=2&select3=1
Do you really need to use Javascript for that? If you give all three select boxes the same "name" attribute, the values will be sent to the server as a comma-delimited list.
Just make sure that you do a trim of each element when you do a split, as some browsers will put spaces after the commas.

I want to set re-select option in , I know there is a function to do that for single element using javascript but I use it as an array so I need to set the value inside the loop su as this example:
<select name="days" value = "3">
<option value="1">Sat</option>
<option value="2">Sun</option>
<option value="3">Mon</option>
<option value="4">Tue</option>
<option value="5">Wed</option>
<option value="6">Thu</option>
<option value="7">Fri</option>
</select>
I think this example will work fine with react, but can I use such a code in normal html and javascript inside the loop.
if you have a database store the day value, instead of use if else function, filter the day on select tag to make the option selected as value in database
basically inside foreach there is a select option tags I need to set selected using the value in database like so:
$('#dynamic_field').append('<select><option value="1">Sat</option><option value="2">Sun</option> ..... </select>
Thanks
In the end of the loop:
$('select[name^=day]',item.id).each(function(a,b){ $(b).val(item.day); });
with that will check for each value and set the value in the database as selected in select form
*Note: item.id and item.day came from database
I have a dropdownlist with a list of countries (all countries)
<select id="Country" onchange="country();">
<option id="3">Japan</option>
<option id="4">Canada</option>
<option id="5">France</option>
<option id="6">Peru</option>
</select>
I have the form in a modal that i want get country value from.
<input id="seachcountry" type="text" class="form-control" name="country">
I have written a JQuery line to get the value from the modal form to the page fields, everything works great but the country select fields are not changing the value.
$("#seachcountry").val($("#modalform").val()).trigger("chang‌e");
thank you for your suggestions!
This will work for you:
Just inject the value of the <input> to <select>.
I have created a snippet for you.
var Tval = $('#seachcountry').val();
$('#Country').val(Tval);
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<select id="Country" onchange="country();">
<option id="3">Japan</option>
<option id="4">Canada</option>
<option id="5">France</option>
<option id="6">Peru</option>
</select>
<input id="seachcountry" type="text" class="form-control" name="country" value="France">
Try this.
function country() {
$("#seachcountry").val($(this).val());
}
For changing value in any select you just need send exist value from this select. In your select options have only ids, but not have value attribute. So if you add value equal to id to change value in the your form to "France" need run following:
$("#selectId").val(5)
Instead of 5 you can obtain value from any other field or else.
If you want set your value to input field when changed in select, you need attach listener that will do all work. It will looks like this:
$("#selectId").on("change", function(){
$("#inputFieldId").val($(this).find(":selected").text());
})
This will set displayed value to select, to set real value just write instead $(this).find(":selected").text() this $(this).val()
I want to display by default a value from a json which is something like
[{"city":"SURAT"},{"city":"BARODA"},{"city":"AHMEDABAD"},{"city":"MUMBAI"}]
this is came from server. I am store this value in $scope.user_all_city and there is one city is provided to user which is i am stored in this
$scope.user_city = "surat";
now my select tag is something like this
<select ng-model="model.user_all_city" ng-options="rm.city for rm in user_all_city" ng-init="model.user_all_city=user_city">
it is display first value as a blank. it is return to me default city when i am print {{mode.user_all_city}} but it is didn't display as selected option in it.
please help me over here and how to call a function in when i am change the value.
Try using ng-repeat instead of ng-options basically the ng-options is not that much descriptive in angularjs.
<select ng-model="cityName" required>
<option>Select city</option>
<option ng-selected="cityName==city" value="{{city}}" ng-repeat="city in cityList"></option>
</select>
here the required attribute will enusre that select city is highlighted in case of null value. and ng-selected will check if that expression is true and the only that object is selected.The value inseide the model=cityName play the role of selected value here.
I have a set of input boxes and you can add more and more sets of these forms if you click the add more button. In my form I can submit data and I have got it to show up when you reload the page. However, I am stuck at making sure all of the fields have values before I run my AJAX. I use Jquery for this project
I cannot use a validation plugin because I am running magento and every time I try running the plugins in "No Conflict Mode" the plugins do not seem to work. Because I am running Magento this means I need to run Jquery in no conflict mode.
I have seen other solutions for this however they are all to do with input boxes and I have 1 input boxes and 2 select boxes. How can I make sure that all the input boxes are filled before and that all the select boxes that are not disabled have something selected before the ajax call?
Here is part of my HTML:
<form>
<input id="12">
<select id="1">
<option disabled="disabled" selected="selected">select please</option>
<option value="01">Option 1</option>
<option value="02">Option 2</option>
</select>
<select id="2">
<option disabled="disabled" selected="selected">Select Please</option>
<option value="01">Option 1</option>
<option value="02">Option 2</option>
</select>
Using a click event, if you use .val() on your <select/>, it will return null if there is no value attribute on your <option/>.
Note: This will not work if you put a value attribute on your options.
Edit: Doing a !== compare will be faster.
$("#submit-button").click(function(){
//if this is true, then it is valid
alert($("#1").val() !== null);
});
You can do it by getting the inputs value into a property.
This script would alert the number of how many inputs aren't complete or missing with base in your structure.
(no jQuery)
var myForm=document.getElementsByTagName("form")[0];
var formSelectors=myForm.getElementsByTagName("select"),
formTextBoxes=myForm.getElementsByTagName("input"),
missing=0;
var i,
length=formSelectors.length;
for(i=0;length>i;i++){
if(formSelectors[i].value===formSelectors[i].children[0].value)
//Check if select value is equal to
//select please or Select please
//MISSING! (select)
missing++
}
length=formTextBoxes.length;
for(i=0;length>i;i++){
if(formTextBoxes[i].value.length===0)
//MISSING! (input)
missing++
}
alert(missing)
Try this:
if($('#12').val()!='') {
// your code
}
What I'm trying to do is give my textfield a value based an an option is select form my drop down. For example: I have 2 fields, a drop down and a textfield. I select Facebook from the dropdown and the value "http://www.facebook.com/" appears in my textfield. How can I achieve this effect? I know that I have to call a function onchange of the drop down but that's pretty much everything I know. Remember that I'm not trying to copy the exact selected value from the dropdown to the textfield here.
example markup
<select>
<option value="http://www.facebook.com">Facebook</option>
<option value="http://www.twitter.com">Twitter</option>
</select>
<input type="text" />
jquery
$('select').change(function() {
$('input[type="text"]').val(this.value);
});
Here's a fiddle
In response to your comment, there are a number of ways to do it (a switch statement, if/elseif statement etc), the easiest would probably be to create an object mapping the text to the corresponding url:
var urlFromText = {
'Facebook' : 'http://www.facebook.com/',
'Twitter' : 'http://www.twitter.com/'
};
Then, in your change handler, you can simply use:
$('input[type="text"]').val(urlFromText[$('option:selected', this).text()]);
Here's an example
HTML
<select id="network">
<option value="http://www.facebook.com">Facebook</div>
<option value="http://www.twitter.com">Twitter</div>
</select>
<input id="network-txt"/>
Jquery
$("#network").change(function(){
$("#network-txt").val($(this).val());
});
