I need to record user preferences on a range of five projects by having them select from one of five radio buttons (5 for each project) which will be marked as 'first choice', 'second choice', etc... but I don't know how to go about recording this on the server (node.js express).
In case I'm not making myself clear, in an ideal world I'd have something like...
//Student Project Preferences
app.get('/api/studentPrefs', function (req, res) {
console.log("Route API/studentPrefs");
console.log(req.query.name);
var project_1 = req.query.project_1,
project_2 = req.query.project_2,
project_3 = req.query.project_3,
project_4 = req.query.project_4,
project_5 = req.query.project_5;
SUPER-pseudo-code...
----------
if(project_1 || project_2 || project_3 || project_4 || project_5 == 'choice_1') {
INSERT INTO db (choice_1) VALUES (relevant topic)
}
else if(project_1 || project_2 || project_3 || project_4 || project_5 == 'choice_2') {
....etc
}
});
<fieldset>
<legend> Please choose your prefered project </legend>
<form id="studentPrefsForm" action="api/studentPrefs" method="get">
<label for="projectChoice_1">Project Choice 1</label>
<input type="radio" name="project_1" value="choice_1" />

</form>
</fieldset>
(Sorry if the above JS explanation is a little too pseudo, I hope it's understandable)
I know there are some issues with my 'ideal' solution, such as the IF statement not returning which project value is 'choice_1/2/3/4/5' so that I can write the project name into the relevant choice_x column in the db, but at this point I'll take anything.
As previously mentioned, I am a first year student so if you can see a better way of doing this, I am very much open to suggestions or critisism, and thanks again.
Even though your JS code could be optimized it will do fine.
What you wrote is the client-side of the page. Depending on the platform/language you are using you need to pass these values to the server-side where the saving will happen.
Let us know what language you are using on the server side - php, .NET, etc.

I am working on making a form that should take the three questions in the form and add them up. If the end value is equal to three it should open call another function called toggletab() when the submit button is clicked. I tried this with it telling me pass or false depending on the value but it won't work. I am not good at JavaScript and it is really confusing to me. It looks like it is running each question separately instead of waiting until the end and calculating them all together. I cannot figure out why this is happening. I also am not sure how to call another function that is in a separate file if someone would know how to do that.
Thank you. This is the HTML

This is the JavaScript
function getscores1(score1) {
var getscores1 = (score1.value);
sendScores(getscores1);
}
function getscores2(score2) {
var getscores2 = (score2.value);
sendScores(getscores2);
}
function getscores3(score3) {
var getscores3 = (score3.value);
sendScores(getscores3);
}
function sendScores(getscores1, getscores2, getscores3){
var total = getscores1 + getscores2 + getscores3;
answer(total);
}
function answer(total) {
if (total == 3) {
document.getElementById('totalScore').innerHTML = "false";
} else{
document.getElementById('totalScore').innerHTML = "pass";
}
}
The variables your functions are defining are not global. Their values disappear after the function returns. So your sendScores function does not actually have access to those values unless you pass them as arguments. But while sendScores takes 3 arguments, you are only sending one (the one you have access too when you call the function).
One option would be to store these as global variables, but global variables are Generally Evil™. Alternatively, you can get all the values when you click submit. Here is a working example. Note this does not catch the case when the user does not respond to one or more of the questions. Click the "run snippet" button below to see it in action.
For your final question, you can put your js in a separate file and then put <script src="path/to/your/file/js"></script> in your html to load it.
function answer(total) {
var score = 0;
if (document.getElementById('exp_yes').checked) {
score++;
}
if (document.getElementById('chg_yes').checked) {
score++;
}
if (document.getElementById('sus_yes').checked) {
score++;
}
if (score > 0) {
document.getElementById('totalScore').innerHTML = "false";
} else {
document.getElementById('totalScore').innerHTML = "pass";
}
}

I'm setting up a multiple choice questionnaire with the responses being handling by radio buttons labelled A, B, C and D.
I want to identify the answer to each question by getting the form ID and the clicked button value, so that, for example, a response using the first set of radio buttons might be 1B and the second, 2D and so on (the form ID script is already up and running).
I need this to work on a page with multiple sets of radio buttons
Here is the HTML:
<form class="toeic_pages" id="1">
<label class="item1">
<input type="radio" value="A" name="toeic"/>
<div class="radio-image"></div>
</label>
<label class="item2">
<input type="radio" value="B" name="toeic"/>
<div class="radio-image"></div>
</label>
<label class="item3">
<input type="radio" value="C" name="toeic"/>
<div class="radio-image"></div>
</label>
<label class="item4">
<input type="radio" value="D" name="toeic"/>
<div class="radio-image"></div>
</label>
</form>
...
<form class="toeic_pages" id="2">
<label class="item1">
<input type="radio" value="A" name="toeic"/>
<div class="radio-image"></div>
</label>
<label class="item2">
<input type="radio" value="B" name="toeic"/>
<div class="radio-image"></div>
</label>
<label class="item3">
<input type="radio" value="C" name="toeic"/>
<div class="radio-image"></div>
</label>
<label class="item4">
<input type="radio" value="D" name="toeic"/>
<div class="radio-image"></div>
</label>
</form>
However, while I've been able to get a checked radio button value using this:
jQuery('input[name=toeic]').change(function(){
var invar = jQuery('input[name=toeic]:checked').val();
alert(invar);
});
The script is only effective within the first row of buttons clicked.
To illustrate, if in the first row of buttons to be accessed, button B is clicked then B is displayed (correct).
But, if in another row, button C clicked, B is displayed (incorrect) .. and B continues to be displayed for all subsequent button clicks. I've checked out the SO pages on this but I haven't been able to find a solution - the issue seems to be multiple sets of radio buttons.
Any help would be very much appreciated
You could do something like this :
$(document).ready(function() {
$("#finish").click(function() {
var answersList = [];
//Loop over all questoins
$(".toeic_pages").each(function() {
var questionId = $(this).attr("id");
var answer = $("input[name='toeic']:checked", $(this)).val();
//if Answer isnt provided do not update the answersList
if (answer !== undefined) {
answersList.push({
question: questionId,
answer: answer
});
}
});
console.log(answersList);
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form class="toeic_pages" id="1">
<label class="item1">
<input type="radio" value="A" name="toeic" />
<div class="radio-image"></div>
</label>
<label class="item2">
<input type="radio" value="B" name="toeic" />
<div class="radio-image"></div>
</label>
<label class="item3">
<input type="radio" value="C" name="toeic" />
<div class="radio-image"></div>
</label>
<label class="item4">
<input type="radio" value="D" name="toeic" />
<div class="radio-image"></div>
</label>
</form>
...
<form class="toeic_pages" id="2">
<label class="item1">
<input type="radio" value="A" name="toeic" />
<div class="radio-image"></div>
</label>
<label class="item2">
<input type="radio" value="B" name="toeic" />
<div class="radio-image"></div>
</label>
<label class="item3">

<div class="radio-image"></div>
</label>
<label class="item4">
<input type="radio" value="D" name="toeic" />
<div class="radio-image"></div>
</label>
</form>

I think this is exactly what you need.
$('#1 input').on('change', function() {
alert($('#1').attr('id')+$('input[name=radioName]:checked', '#1').val());
});
$('#2 input').on('change', function() {
alert($('#2').attr('id')+$('input[name=radioName]:checked', '#2').val());
});
$('#3 input').on('change', function() {
alert($('#3').attr('id')+$('input[name=radioName]:checked', '#3').val());
});
$('#4 input').on('change', function() {
alert($('#4').attr('id')+$('input[name=radioName]:checked', '#4').val());
});

Credits to the owner of this answer #Peter J in this question How can I know which radio button is selected via jQuery?
I'm working on a customer survey where I ask the customer if they'd like to be contacted about their experience. If they select yes, additional questions follow asking them their preferred method of contact & the info for the selected method.
HTML
<b>May we contact you about your experience?</b>
<br/>
<input type="radio" name="Contact" id="ContactYes" value="Yes" required />
<label for="ContactYes">Yes</label>
<input type="radio" name="Contact" id="ContactNo" value="No" />
<label for="ContactNo">No</label>
<br />
<br />
<b>Select your preferred method of contact:</b>
<br/>
<input type="radio" name="FormOfContact" id="Phone" value="Phone" />
<label for="Phone">Phone</label>
<input type="radio" name="FormOfContact" id="Email" value="Email" />
<label for="Email">Email</label>
Basically, what I'd like to know is how can I make 'FormOfContact' a required field ONLY when the user selects "Yes" to being contacted?
If you create an onchange event for the radio buttons, you can check whether "yes" or "no" is selected. If "yes" is selected, add the attribute "required=true" to the second field.
ELEMENT.setAttribute("required",true)
A bit of javascript could help.

I am trying to change the value of a textbox based on the selection a group of 4 radio buttons. This is not the actual html code, but a simplified version:
<input type="radio" name="radiogroup" id="radiogroup" value="5" />
<input type="radio" name="radiogroup" id="radiogroup" value="10" />
<input type="radio" name="radiogroup" id="radiogroup" value="15" />
<input type="radio" name="radiogroup" id="radiogroup" value="20" />
<input type="text" name="amount" id="amount" />
So what I am trying to do is fill the textbox named "amount" with either 5, 10, 15 or 20 based on which radio button is selected.
I am new to jquery and everything I tried did not work.
Thank you in advance for any help.

You can easily do this by adding class.
Working Fiddle
HTML:
<input type="radio" name="radiogroup" id="radiogroup" class="radiogroup" value="5" />
<input type="radio" name="radiogroup" id="radiogroup" class="radiogroup" value="10" />
<input type="radio" name="radiogroup" id="radiogroup" class="radiogroup" value="15" />
<input type="radio" name="radiogroup" id="radiogroup" class="radiogroup" value="20" />
<input type="text" name="amount" id="amount" />
JS:
$('.radiogroup').change(function(e){
var selectedValue = $(this).val();
$('#amount').val(selectedValue)
});
ID's are unique, and an ID can only be used on one element in the current document, so change it to classes.
Then attach a change event handler to the radios, get the checked one, and set the value of the text input to the checked radios value
$('.radiogroup').on('change', function() {
$('#amount').val( this.value );
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="radio" name="radiogroup" class="radiogroup" value="5" />
<input type="radio" name="radiogroup" class="radiogroup" value="10" />
<input type="radio" name="radiogroup" class="radiogroup" value="15" />
<input type="radio" name="radiogroup" class="radiogroup" value="20" />
<br /><br />
<input type="text" name="amount" id="amount" />
Something like:
$('input[name="radiogroup"]').click(function()
{
$('#amount').val($(this).val())
})
I have the following idea. My view contains 3 input fields and radio buttons which need to work each other.
Firstly when the view is displayed you can see the input fields only. If the user clicks on one of the input fields the other fields disabled and the radio buttons to this input fields are showing. If the user want to use an other input field of these three then he needs to click on one of the radio buttons then the other two input field will disabled.
Here is the currently code:
...
<input type="text" name="Id" ng-model="search.id" ng-click="disabled = !disabled" ng-disabled="..." />
<input type="radio" class="radio" ng-hide="!disabled" />
...
<input type="text" name="Name" ng-model="search.name" ng-click="disabled = !disabled" ng-disabled="disabled" />
<input type="radio" class="radio" ng-hide="!disabled" />
...
<input type="text" name="Age" ng-model="search.age" ng-click="disabled = !disabled" ng-disabled="disabled" />
<input type="radio" class="radio" ng-hide="!disabled" />
How can I realise that? Currently the first input field works.
Try to give a value to disabled
...
<input type="text" name="Id" ng-model="search.id" ng-click="disabled = 1" ng-disabled="disabled!=1" />
<input type="radio" class="radio" ng-hide="disabled==1" />
...
<input type="text" name="Name" ng-model="search.name" ng-click="disabled = 2" ng-disabled="disabled!=2" />
<input type="radio" class="radio" ng-hide="disabled==2" />
...
<input type="text" name="Age" ng-model="search.age" ng-click="disabled = 3" ng-disabled="disabled!=3" />
<input type="radio" class="radio" ng-hide="disabled==3" />
this can certainly work, just make sure you are using different $scope variables for each control:
<input type="text" name="Id" ng-model="search.id" ng-click="disabledId = !disabledId" ng-disabled="disabledId" />
<input type="radio" class="radio" ng-show="disabledId" ng-click="disabledName = true; disabledId=false; disabledAge=true"/>
...
<input type="text" name="Name" ng-model="search.name" ng-click="disabledName = !disabledName" ng-disabled="disabledName" />
<input type="radio" class="radio" ng-show="disabledName" ng-click="disabledName = false; disabledId=true; disabledAge=true"/>
...
<input type="text" name="Age" ng-model="search.age" ng-click="disabledAge = !disabledAge" ng-disabled="disabledAge" />
<input type="radio" class="radio" ng-show="disabledAge" ng-click="disabledAge=false; disabledId = true; disabledName=true"/>
While this should work here, I recommend not to put so much JS-code into the HTML, better would be to add a method on $scope like $scope.radioClicked(buttonId) and then call this method on ng-click.
Also using ng-show instead of ng-hide helps readability - no double negation.
I've changed my input fields. It is a possible solution but only I need the interaction with radio buttons and the input fields.
<input type="text" name="Id" ng-model="search.id" ng-click="nameDis = !nameDis;ageDis = !ageDis" ng-disabled="idDis" />
<input type="radio" class="radio" ng-hide="!idDis" />
...
<input type="text" name="Name" ng-model="search.name" ng-click="idDis = !idDis;ageDis = !ageDis" ng-disabled="nameDis" />
<input type="radio" class="radio" ng-hide="!nameDis" />
...
<input type="text" name="Age" ng-model="search.age" ng-click="nameDis = !nameDis;idDis = !idDis" ng-disabled="ageDis" />
<input type="radio" class="radio" ng-hide="!ageDis" />
