need to display other field on live status of other field - javascript

When a user selects a state from a state drop-down, it will display a list of high-schools in a drop-down field.
I am able to display the high schools once the user selects a state, but I am having trouble when the user submits the form w/o selecting a high school. If they do not select a high school, it will not display the form.
That is not really the problem, that is one of the ways the form can fail validation, which brings me to my question.
When the user fails validation, it will display the same form with the fields filled in the info they inputted before submitting the form.
The state drop-down is pre selected with the state they selected, but the high school drop down is no where to be seen. If I unselect the state drop-down, then re-select a state, then the high school list will display.
I am using a bind change on the #state field.
How can I display the high school field w/o having to wait for a click or change on the state field?
<select name="state" id="state">
<option></option>
<option value="NY">NY</option>
<option value="TX">TX</option>
</select>
<select name="high_school" id="high_school">
<option></option>
<option value="Bayside High">Bayside High</option>
<option value="Ridgemont High">Ridgement High</option>
</select>
$("#high_school").hide();
$('#state').bind('change', function() {
$("#high_school").show();
});
I assume I'll need to keep an eye on #state on load

Your are right, about keeping an eye on #state on load.
//check to see if something in #state is selected, if not hide #high_school
if($("#state").val() == '') {
$("#high_school").hide();
}
$('#state').bind('change', function() {
$("#high_school").show();
});

Try choosing #state, and refresh the frame :)

How to open disabled fields in Selenium

I'm trying to fill a form using Selenium, but the form has a disabled field.
Disabled field
The field is only editable when I modify the field above it.
Open field
When I set the value directly using the code below, the field is not open for editing
js.executeScript("document.getElementById('field_id').value='" + brand + "'");
Example
I tried to simulate the click in the field, press the tab key, press the enter key, but none had any effect.
Is there any way for me to trigger the same event that the user is performing on the screen to release the field through selenium or javascript?
In the HTML code, the options are not listed, so the options are loaded from a javascript function that is executed after filling the first field
Options
Because I really liked it I'll copy Tschallackas Intro:
Your test is flawed. You are not following user behaviour.
Sadly I totally disagree with the rest of the answer :(
I would like to ask WHY are you trying to use JavaScript?
Is this something a real User would do? I really doubt it!
The crucial thing with End2End-Tests is to simulate your User behaviour as close as possible. Therefore I would suggest to use the Webdriver to do things like that in your Seleniumtest.
Select dropdown = new Select(webdriver.findElement(By.id("field_id")));
dropdown.selectByVisibleText("ONESOURCE");
(Assuming you are using Java by the tag on your question)
Your test is flawed. You are not following user behaviour.
You are doing:
js.executeScript("document.getElementById('field_id').value='" + brand + "'");
Which tries to change a value on a dropdown. This doesn't work because dropdowns work via a selectedIndex, which you can use to get the correct value from the options collection on the dropdown element.
Also, when a user changes a value, a change event is triggered, which notifies other scripts that listen to that event that something has changed. You need to emulate this too to trigger your change script.
js.executeScript("let select = document.getElementById('field_id');"+
"select.selectedIndex = 1;/* change this to the value corresponding to the correct index of the value you wish to test. */"+
"select.dispatchEvent(new Event('change'));");
See the example below for how the javascript should work.
document.getElementById('field_id').addEventListener('change', (e) => {
if(e.target.options[e.target.selectedIndex].value > 1) {
document.getElementById('the_disabled').disabled = false;
}
else {
document.getElementById('the_disabled').disabled = true;
}
});
document.getElementById('trigger').addEventListener('click',() => {
let select = document.getElementById('field_id');
select.selectedIndex = 1;// change this to the value corresponding to the correct index of the value you wish to test.
select.dispatchEvent(new Event('change'));
});
<select id="field_id">
<option value="1">--none--</option>
<option value="2">COMPANY A</option>
<option value="3">COMPANY B</option>
</select>
<BR/>
<select id="the_disabled" disabled="disabled">
<option value="0">--none--</option>
<option value="1">SELECT A</option>
<option value="2">Select B</option>
</select>
<BR/>
<button id="trigger">Trigger selenium emulation</button>

How to select a dropdown element on a website using javascript code?

I am writting a javascript program that needs to be able to select an element on a dropdown and then continue browsing. My problem is that even though I can select a dropdown element and that I can see the dropdown change on the website, the element I have selected doesn't seem to be "registered" and when I continue my browsing, the dropdown is back to the default option.
I figured out that maybe the website needs a mouse click to register the change so I have tried clicking on the dorpdown after selecting the right option but it still doesn't work.
Here is the different codes I have tried and which seems to both have the same problem :
//first try:
document.getElementById('SingleOptionSelector-0').selectedIndex = 2;
//second try :
document.getElementById('SingleOptionSelector-0').value = '3';
I tried to click on the dropdown menu like this:
document.getElementById('SingleOptionSelector-0').click();
But it doesn't expand. It's like the click is not registered which seems very strange to me because when I click somewhere else on the web-page it works just fine
I have seen a lot of questions about how to interact with a dropdown menu,but no one else seems to have the problem that when you change the value it is not registered by the web-page
The relevant HTML is below:
<select class="single-option-selector single-option-selector-product-template_original product-form__input" id="SingleOptionSelector-0" data-index="option1">
<option value="1">Hamburger</option>
<option value=" 2">fries</option>
<option value="3">Coke</option>
<option value="4">Diet Coke</option>
</select>
edit : It seems that I was not clear enough. An example of my problem is the website https://www.xhibition.co/collections/air-jordan/products/jordan-23-engineered-full-zip-jacket?variant=29510378848328 . When I use one of these methods to change the "size" dropdown, I can see it changing but when going to the basket, the size of the element I just added is the default one ('M'). That's what I mean by the website "not registering" the dropdown change.
Try this.
document.getElementById('myDropDown').value = "2"
Your question is kind of vague, but I think the sample below should give you a good idea of how to get and set select element values and also how to use addEventListener to know when a change event has taken place:
const selectEl0 = document.querySelector('#SingleOptionSelector-0');
const selectEl1 = document.querySelector('#SingleOptionSelector-1');
const onChange = e => selectEl1.value = e.target.value;
selectEl0.addEventListener('change', onChange)
The second select element will update it's value when the first one changes:<br/>
<select class="single-option-selector single-option-selector-product-template_original product-form__input" id="SingleOptionSelector-0" data-index="option1">
<option value="1">Hamburger</option>
<option value="2">fries</option>
<option value="3">Coke</option>
<option value="4">Diet Coke</option>
</select>
<select class="single-option-selector single-option-selector-product-template_original product-form__input" id="SingleOptionSelector-1" data-index="option1">
<option value="1">Hamburger</option>
<option value="2">fries</option>
<option value="3">Coke</option>
<option value="4">Diet Coke</option>
</select>

AngularJS ng-selected with if else condition

I have a select statement using ng-repeat on the options and am looking for a way that if an option condition isn't met to default to a specific option.
Specifically, a drop down for country code. If an country is set, then make that the ng-selected, but if is set then default to the USA. When the user selects or changes the country, the 'state' field automatically changes to that country's states/provinces.
The below code works as is, but now I need to figure out how to set the default to USA. Can this be done with an if/else in the ng-selected condition?
<select class="registerFields" id="user_country" ng-init="selectCountry(accountItem.user_country)" ng-change="selectCountry(accountItem.user_country);" ng-model="accountItem.user_country" ng-blur="setInfo('accountItem','user_country')">
<option value="">Country</option>
<option ng-selected="country.code == accountItem.user_country"
ng-repeat="country in countries" value="{{country.code}}">{{country.code}}: {{country.country}}</option>
</select>

<HTML> Can't select same values in drop down list. Validation <HTML>

I want to be able to validate my drop down lists.
There are 6 destinations, and if the user was to select Cardiff in the "Departure" drop down, then if they was to select Cardiff again in the "Destination" drop downn, it should give a message box saying 'Destination can't be the same as Departure'.
This needs to be done in HTML and JavaScript/JQuery.
Thanks
Departure: <br> <select>
<option value="" disabled selected>Please Select</option>
<option>Birmingham</option>
<option>Bristol</option>
<option>Cardiff</option>
<option>Liverpool</option>
<option>London</option>
<option>Manchester</option>
</select><br><br>
Destination: <br><select>
<option value="" disabled selected>Please Select</option>
<option>Birmingham</option>
<option>Bristol</option>
<option>Cardiff</option>
<option>Liverpool</option>
<option>London</option>
<option>Manchester</option>
</select><br><br>
Very quick example but essentially you can do something like this:
Fiddle: http://jsfiddle.net/6hojsqhr/
$('#select1, #select2').on('change',
function () {
if ($('#select1').val() == $('#select2').val()) {
// Display message
}
else {
// Remove message if displayed
}
}
);
Well I am feeling slightly called out so let me explain what is happening here.
$('#select1, #select2').on('change',
First I select the two inputs we want to test against and attach a change event to them. This will fire this event every time the input's value changes and loses focus.
if ($('#select1').val() == $('#select2').val()) {
// Display message
}
else {
// Remove message if displayed
}
In this function we get both values of the two inputs we want to test for equivalent values. If they are the same we display the message. If not don't do anything or in some cases remove a displayed message.
Again this is a very quick solution that can be much more dynamic and thought out depending on your specific scenario. This is very simple JavaScript/jQuery. I would recommend doing some reading and perhaps free courses online that can teach these basics. A simple google search will pull up a ton of examples of code like this and websites that teach how to do this.

Select already selected item in dropdown/select - list

I've been searching for an answer to this question for quite some time now, with no luck, or buggy solutions at max.
The problem im facing is that i have a select element which (obviously) doesn't fire the "onchange" event when selecting the already selected item.
Like this:
<select onchange="alert(this.value);">
<option>1</option>
<option>2</option>
<option>3</option>
</select>
Now, say i select item 1 first.
Then afterwards i need to be able to select item 1 again.
This feature is extremely important to the success of the project I'm working on.
Any help is greatly appreciated.
Edit: (More info)
This functionality is needed as im working on a project with a google maps where users are presentet with a dropdown to quickly jump to a country (Eg you select "Spain" in the dropdown, google maps sets spain as your view.
the problem comes when you want to go to spain, then drag around the map, and end up in italy. Now you want to go back to spain, but you cant select it from the dropdown until you select something else first. My boss doesn't like that :)
Edit2: Solution
So by now theres a few solution.
One of them is to throw the action onblur (when unfocusing the control) this could work, as i could blur the list onchange, but still for people selecting the same item again, the trigger to blur the control wont go, and unless they switch focus by them self, they wont see the changes to the map.
Still i cannot understand why it should be so hard to find some event that excutes on option select / click / blur or whatever.. ill keep looking myself, and check back here a tad later.
Edit 3: Final solution
Right so i finally managed to get this working, not exactly as it was ment to be, but close enough, atleast for now anyways.
The solution i came up with was to add a "Please select country" option at the top of the select.
Then on change, i would change the text, and value of "Please select country" to that of the selected item, and reset the selectedindex to 0.
This way, when selecting, say, Spain, it will be at the top of the list in a disabled state, and further down in a working state. so now you can click spain in the middle of the list to go back to spain even though it is still selected (the top item is)
Quite neat, idea was supplied from a coworker.
script is as following:
var dummyOption;
function setdummyCountry(obj)
{
var selectedOption = obj.options[obj.selectedIndex];
if (dummyOption != null) {
dummyOption.text = selectedOption.text;
dummyOption.value = selectedOption.value;
}
else {
dummyOption = document.createElement("option");
dummyOption.text = selectedOption.text;
dummyOption.value = selectedOption.value;
dummyOption.setAttribute("disabled", "true");
obj.options[0] = dummyOption;
}
obj.selectedIndex = 0;
}
<select onchange="setdummyCountry(this);">
<option value="">Please select country</option>
<option value="ES">spain</option>
<option value="SE">sweden</option>
<option value="NO">norway</option>
</select>
i hope this will help someone!
And to those who tried to help me thank you for your ideas and time.
I think there is no way change event is gonna fire if the same item is selected. We were facing the same issue so what we did was a simple usability hack: When an item is selected we show to the user the item selected in a span and reset the value of dropdown to its default value (--Select--).
HTH
this is maybe not excactly what do you want, but this another alternative that you can decide.
after select the option, get it back to default(the empty one/first) option
<select onchange="alert(this.value);this.value='';">
<option value='' selected='selected'></option>
<option>1</option>
<option>2</option>
<option>3</option>
</select>
or you can make
<select onblur="alert(this.value);">
<option>1</option>
<option>2</option>
<option>3</option>
</select>
but this way will call your function (alert) when user leave/blur/unfocus the list :p
I was looking for the solution for the same scenario and ended up writing a angularjs directive for the same -
guthub link - angular select
Used element[0].blur(); to remove the focus off the select tag. Logic is to trigger this blur on second click of the dropdown.
as-select gets triggered even when user selects the same value in the dropdown.
DEMO - link
you can use onclick function and maintain a count for that, once you get same target.value twice, then you can perform your onchange fuctionality there.
I have implemented this in Vue.js
Select block:
<select
id="status"
name="status"
#change="
onChangeStatus(un.id, $event)
"
#click="
onChangeStatus(
un.id,
$event,
'same'
)
"
class="form-control"
:value="un.status"
>
<option value="Uncleaned">Uncleaned</option>
<option value="Partially Taken for cleaning">
Partially Taken for cleaning
</option>
<option value="Fully Taken for cleaning">
Fully Taken for cleaning
</option>
</select>
Kept count=0 initially.
I have used same function on both events, checked conditions and returned data accordingly
onChangeStatus(id, e, type) {
if (type === "same") {
if (e.target.value === "Partially Taken for cleaning") {
this.count += 1;
if (this.count === 2)
this.$router.push({
name: "NewPage",
params: {
id: id,
status: e.target.value,
},
});
}
} else {
this.$router.push({
name: "NewPage",
params: {
id: id,
status: e.target.value,
},
});
}
},
