Remove Radio Buttons from a Quiz - javascript

We are trying to get a Quiz written in Javascript running on our site. We need to remove Radio buttons because currently, they are not linking through to the next question.
Here is the page in question:
http://stephanieshipper.com/test/
And below is the piece of code from the .js file that contains the Radio buttons. How would I remove these without breaking the rest of the functionality? So far, when I have taken out the Radio buttons, the text links also break.
function updates(questions) {
for (i = 0; i < 20; i++) {
$("body").append("<article><p>" + questions[i] + "</p><input id='question-" + (i*10) + "-1' type='radio' order='1' name='question-" + i + "-0'><label for='question-" + (i*10) + "-1'>exactly like me</label><br><input id='question-" + (i*100) + "-2' type='radio' order='2' name='question-" + i + "-0'><label for='question-" + (i*100) + "-2'>sort of like me</label><br><input id='question-" + (i*1000) + "-3' type='radio' order='3' name='question-" + i + "-0'><label for='question-" + (i*1000) + "-3'>not really like me</label><br><input id='question-" + (i*10000) + "-4' type='radio' order='4' name='question-" + i + "-0'><label for='question-" + (i*1000) + "-4'>not at all like me</label><br></article>");
}
motions();
}
function motions() {
var step = 1;
results = [];
var order;
$("body > article > label").on("click", function() {
$(this).parent().hide(250);
if (step < 20) {
$(this).parent().next().show(250);
order = parseInt($(this).prev().attr("order"));
results[step-1] = order;
step++;
} else {

why my for loop is infinite here

below is the js code for wikipedia search project. I am getting infinite for loop even though it had condition to stop repeating the loop. I am stuck in this problem.
$(document).ready(function() {
$('.enter').click(function() {
var srcv = $('#search').val(); //variable get the input value
//statement to check empty input
if (srcv == "") {
alert("enter something to search");
}
else {
$.getJSON('https://en.wikipedia.org/w/api.php?action=opensearch&search=' + srcv + '&format=json&limit=20&callback=?', function(json) {
$('.content').html("<p> <a href ='" + json[3][0] + "'target='_blank'>" + json[1][0] + "</a><br>" + json[2][0] + "</p>");
/*for loop to display the content of the json object*/
for (i = 1; i < 20; i++) {
$('p').append("<p><a href ='" + json[3][i] + "'target='_blank'>" + json[1][i] + "</a>" + json[2][i] + "</p>");
}
});
}
});
});
You are appending to each and every one of <p> in page.
Since your for loop appends even more <p> (and you possibly have a high number of <p> elements in your page beforehand) you overflow your call stack.
You probably wanted to append to a specific <p>. Try giving an id to your selector.
from what i can see in the url you need to do the following:
loop over the terms found and select the link based on the index of the element, chose a single element .contentto append the data not a set of elements p, this will increase the number of duplicated results
$.getJSON('https://en.wikipedia.org/w/api.php?action=opensearch&search='+srcv+'&format=json&limit=20&callback=?', function(json){
$.each(json[1],function(i,v){
$('.content').append("<p><a href ='"+json[2][i]+"'target='_blank'>"+json[0]+"</a>"+v+"</p>");
});
});
see demo: https://jsfiddle.net/x79zzp5a/
Try this
$(document).ready(function() {
$('.enter').click(function() {
var srcv = $('#search').val(); //variable get the input value
//statement to check empty input
if (srcv == "") {
alert("enter something to search");
}
else {
$.getJSON('https://en.wikipedia.org/w/api.php?action=opensearch&search=' + srcv + '&format=json&limit=20&callback=?', function(json) {
$('.content').html("<p> <a href ='" + json[3][0] + "'target='_blank'>" + json[1][0] + "</a><br>" + json[2][0] + "</p>");
/*for loop to display the content of the json object*/
var i = 1;
for (i; i < 20; i++) {
$('p').append("<p><a href ='" + json[3][i] + "'target='_blank'>" + json[1][i] + "</a>" + json[2][i] + "</p>");
}
});
}
});

jQuery - why do 2 elements get appended when I click an icon

I've created a JSfiddle here:
basically I have a form that will allow users to input additional sections... but when I have added more than 2 units and then proceed to click on the 'plus' (+) icon I get more than 1 element created in that section... its probably something elementary, but any info will help.
Move your Click functions out of the click function
//add unit input box and increment click counter by one.
addUnit.click(function () {
unitCounter += 1;
unitElementCount = jQuery(".unit-element").length;
if (unitCounter <= 4) {
error.hide();
container.append('<table id="unit-' + unitCounter + '-div" class="create-course-table-element unit-element"><tr><td><label class="unit-label">Unit ' + unitCounter + '</label></td><td><input class="create-course-input-element unit-input" id="unit-id-' + unitCounter + '" name="unit-' + unitCounter + '" /><div id="delete-unit-' + unitCounter + '" class="ui-icon ui-icon-circle-close del-unit" title="Delete unit"></div></td></tr><tr><td align="center">Sections</td><td><div id="add-section-icon-' + unitCounter + '" class="ui-icon ui-icon-plus add-section-icon"></div></td></tr></table><div id="section-id-' + unitCounter + '-div" class="this-section"></div>');
} else if (unitElementCount == 4) {
unitCounter = 5;
error.html("");
error.fadeIn(1500);
error.append("<p class='error-message'>Note: You are only able to add 4 units to a given course. Each unit allows you to add 10 separate sections of content; therefore you may add a total of 40 different sections to a given course. If the material requires more units, you should consider dividing the course into 2 parts.</p>");
}
});
//This part has been slightly modified and moved out of the addUnit.click() function
var counterSecTwo = 0;
var counterSecThree = 0;
var counterSecFour = 0;
jQuery(document).on("click", "#add-section-icon-2",function () {
counterSecTwo += 1;
var container = jQuery("#section-id-2-div");
container.append("<p>test "+counterSecTwo+"</p>");
});
jQuery(document).on("click", "#add-section-icon-3",function () {
counterSecThree += 1;
var container = jQuery("#section-id-3-div");
container.append("<p>test "+counterSecThree+"</p>");
});
jQuery(document).on("click", "#add-section-icon-4",function () {
counterSecFour += 1;
var container = jQuery("#section-id-4-div");
container.append("<p>test "+counterSecFour+"</p>");
});
});
Here I am binding the click handlers to Document as the elements do not exist yet: you could also add the event listener when you create the actual element.

jQuery adding pages

I have made an really ugly code, but i was going to fix it when i was done with it.. But i didn't come that far >_<
i post my code here and some information under it.
$(document).on('click', '.cogwheel', function() {
var link = $(this).data('pageid');
$(".pages").not(".page" + link).hide();
$(".links").not("#link-" + link).show();
$("#link-" + link).toggle();
$(".page" + link).toggle();
});
$(document).on('click', '.deletecross', function() {
$(".deleteClass" + $(this).data('pageid')).remove();
var total = parseFloat($(".hiddenCounter").val()) - 1;
$(".hiddenCounter").val(total);
var this_val = $(".pagae" + $(this).data('pageid')).val();
this_val.replace($(".pagae" + $(this).data('pageid')).val(), "");
$(".pagae" + total).val(this_val);
});
$(document).on('keyup', '.pages', function() {
var pageID = $(this).data('pageid');
var pages = $(".pagae").val();
$(".pagae" + pageID).val($(this).val());
$(".pagetest" + pageID).html($(this).val());
$(".pagae").val(pages + $(this).val());
$("#link-" + pageID).html($(this).val());
});
message = new Array();
jQuery.fn.update_textarea = function(test) {
//for (i=0;i<test;++i) {
if (message[test]) { $(".MenuLinks").append('<tr><td width="150">Sida ' + test + '</td><td align="right"><span class="glyphicon glyphicon-cog"></span></td></tr>');$("#articles_textarea").append('<h2>askda</h2><textarea id="editor-1"></textarea>'); }
else {
message[test] = '';
var TDRow1 = '<tr class="deleteClass' + test + '"><td width="150">Sida ' + test + '<input type="text" name="pages[]" value="Sida ' + test + '" class="pages page' + test + '" data-pageid="' + test + '"></td>';

var TDFake = '<td></td>';
if (test != 1) {
var TRRow = TDRow1 + TDRowRemove + TDRow2;
}
else {
var TRRow = TDRow1 + TDFake + TDRow2;
}
$(".MenuLinks").append(TRRow); $("#articles_textarea").append('<div id="Sida' + test + '" class="tab-pane"><input type="hidden" class="pagae' + test + '" name="pagae[]" value="Sida ' + test + '"> <h2 class="pagetest' + test + '">Sida ' + test + '</h2><textarea name="editor[]" id="editor-' + test + '" class="editor" data-pageid="' + test + '"></textarea></div>');

/* If no textareas available add a new one */
if (message.length == 0) {
$(this).update_textarea(1);
$("#Sida1").addClass("active");
}
});
This code you can add a page with, delete a page and write a new name for the page, and im using bootstrap so they all got there own "tab"
I was going to use this script to make an article system, and when you post it should insert pages into an own table like pages. And content to another.
But my problem here is, when im trying to remove a "link/page" it removes the page from the menu and everything.
But i dont have a freaking clue how to change the hidden input that has all the names of the pages in it.. So when i post the hidden input i got all pages i have on the page and those i removed..
I know this is some slabby code and i know you could make it better then me..
If you got any ideas or any thing that i can make smaller let me know..

Cant refresh to bottom of page with javascript function containing url variables

I have a few cascading dropdowns on the bottom of my php page. Each time a user selects an option from the dropdown the following function is called to add the value of that option to my url variables. Currently the page refreshes to the top each time which is a huge problem. Normally I would use something like onCLick="window.location='page.htm#bottom';" to refresh to the bottom of the page but the below function stops working when I add the #bottom. Can someone help me adjust this function or give me other ideas that will refresh to the bottom of the page when the function is done.
function reload5(form){
if(document.getElementById('fda1').checked) {
var fda = '1';
}else if(document.getElementById('fda0').checked) {
var fda = '0';
}
var val=form.category.options[form.category.options.selectedIndex].value;
var val2=form.subcat.options[form.subcat.options.selectedIndex].value;
var val3=form.subcat1.options[form.subcat1.options.selectedIndex].value;
var val4=form.subcat2.options[form.subcat2.options.selectedIndex].value;
var comp1=form.mname.options[form.mname.options.selectedIndex].text;
var itemnum=document.getElementById('item').value;
var desc=document.getElementById('desc').value;
var quan=document.getElementById('quan').value;
var list=document.getElementById('list').value;
var uom=form.uom.options[form.uom.options.selectedIndex].text;
self.location='add_products.php#bottom?fda=' + fda + '&desc=' + desc + '&quan=' + quan + '&list=' + list + '&uom=' + uom + '&item=' + itemnum + '&cat=' + val + '&cat2=' + val2 + '&cat3=' + val3 + '&cat4=' + val4 + '&comp=' + comp1 ;
}
So this doesn't work: self.location='add_products.php#bottom?fda=' + fda
But this does : self.location='add_products.php?fda=' + fda
Any idea where to put the #bottom?
The issue is that the hash must come after the query string at the end. See this article. Try this... (I also cleaned up the code)
function reload5(form){
var val=form.category.options[form.category.options.selectedIndex].value,
val2=form.subcat.options[form.subcat.options.selectedIndex].value,
val3=form.subcat1.options[form.subcat1.options.selectedIndex].value,
val4=form.subcat2.options[form.subcat2.options.selectedIndex].value,
comp1=form.mname.options[form.mname.options.selectedIndex].text,
itemnum=document.getElementById('item').value,
desc=document.getElementById('desc').value,
quan=document.getElementById('quan').value,
list=document.getElementById('list').value,
uom=form.uom.options[form.uom.options.selectedIndex].text,
fda;
if(document.getElementById('fda1').checked) {
fda = 1;
} else if(document.getElementById('fda0').checked) {
fda = 0;
} else {
fda = -1;
}
window.self.location.href = 'add_products.php?fda=' + fda + '&desc=' + desc + '&quan=' + quan + '&list=' + list + '&uom=' + uom + '&item=' + itemnum + '&cat=' + val + '&cat2=' + val2 + '&cat3=' + val3 + '&cat4=' + val4 + '&comp=' + comp1 + "#bottom";
}
What I don't understand is why you are not doing something with Ajax that would not cause the page to refresh at all.

How to dynamically assign an id to an image

var intFields = 0;
var maxFields = 10;
function addElement() {
"use strict";
var i, intVal, contentID, newTBDiv, message = null;
intVal = document.getElementById('add').value;
contentID = document.getElementById('content');
message = document.getElementById('message');
if (intFields !== 0) {
for (i = 1; i <= intFields; i++) {
contentID.removeChild(document.getElementById('strText' + i));
}
intFields = 0;
}
if (intVal <= maxFields) {
for (i = 1; i <= intVal; i++) {
intFields = i;
newTBDiv = document.createElement('div');
newTBDiv.setAttribute('id', 'strText' + intFields);
newTBDiv.innerHTML = "<input placeholder='recipient" + intFields + "#email.com' type='text' name='" + intFields + "'/><a href='javascript:removeElement();'><img id='strImg + " + intFields + "' src='images/minus.png' alt='Add A Field'/></a><input type='text' value='" + newTBDiv.id + "'/>";
contentID.appendChild(newTBDiv);
message.innerHTML = "Successfully added " + intFields + " fields.";
}
} else {
for (i = 1; i <= maxFields; i++) {
intFields = i;
newTBDiv = document.createElement('div');
newTBDiv.setAttribute('id', 'strText' + intFields);
newTBDiv.innerHTML = "<input placeholder='recipient" + intFields + "#email.com' type='text' name='" + intFields + "'/><a href='javascript:removeElement();'><img id='strImg + " + intFields + "' src='images/minus.png' alt='Add A Field'/></a><input type='text' value='" + newTBDiv.id + "'/>";
contentID.appendChild(newTBDiv);
message.innerHTML = "Unable to create more than 10 receipient fields!";
}
}
}
My script here dynamically adds up to 10 fields where users will be able to enter an email address and to the right of the text box i add an image of a minus sign that calls another script. I'm having trouble working out how to assign and keep track of the minus signs. I need to be able to have the minus sign script's recognize the text box it is by and remove it. I can write the remove script easily enough but I'm unsure of how to tell the image which text box to remove. Any help, suggestions, or comments are greatly appreciated.
Thanks,
Nick S.
You can add a class to the field called minus and then check through like that. I would suggest using jquery for this.
To add the class
$("#element").addClass("minus");
To remove all elements with that class
$("body input").each(function (i) {
if($(this).attr("class") == "minus"){
$(this).remove();
}
});
The two best options, imo, would be 1) DOM-traversal, or 2) manipulating ID fragments.
Under the first way, you would pass a reference to the element where the event takes place (the minus sign) and then navigate the DOM from there to the get the appropriate text box (in jQuery you could use $(this).prev(), for example).
Under the second way, you would assign a prefix or a suffix to the ID of the triggering element (the minus sign), and the same prefix or suffix to the target element (the text box). You can then (again) generate the appropriate ID for your target element by simple string manipulation of the ID from the triggering element.
Is that sufficient to get you started?
Try adding a class to the field and the same class to the minus sign.
So add this right after the setAttribute id,
newTBDiv.setAttribute('class', 'field' + intFields);
then just remove any elements that have that class.
