I'm asking as a last resort before I tear the last of my hair out. At the moment I am showing an initial 2 divs. The user can then add these two divs below the original as many times as they want. They can also remove the 2 divs if necessary. I am trying to allow reording of the divs using drage and drop. I've tried numerous methods but I just can't get it working. As an extra note, the divs need to reindex themselves once the user has dragged and dropped. Here is the code that I have. Please take into consideration that I have added and deleted lots of code attempts before settling on this basic implementation. Thanks in advance.
Load JQuery
Display first div to end user
<!--Div contains each answer step-->
<div id = "answer_step" class = "answer_step">
<!--This placeholder text is styled from CSS and will empty the div once the user starts typing-->
<div id="answer_step_equation0" class="answer_step_equation" contenteditable="true" placeholder="Enter The Next Solution Step This Question"></div>
<div id="answer_step_description0" class = "answer_step_description" contenteditable="true" placeholder="Enter A Description as to how this step was reached or how to solve the next step"></div>
</div>
</div>
<!-- Buttons to dynamically add and remove answer divs. The remove functionality is added in JQuery for the add button-->
<button id="add_answer_step_button" class="add_answer_step_button">+ Add next Step</button>
This code appends the new divs. I have to put the three divs within a div like above but I can't get it to work.
<!--Script to append/remove div when user clicks on add_answer_step_button-->
<script type = "text/javascript" language = "javascript">
$(document).ready(function() {
<!--This variable gives each new set of answer divs a unique id by appending a number to the end of th id-->
<!--The first set of answer divs will have an id of zero-->
var answer_identifier_number = 1;
$("button.add_answer_step_button").click(function () {
$("div.answer_steps").append('<div id="answer_step_equation' + answer_identifier_number + '" class="answer_step_equation" contenteditable="true" placeholder="Enter The Next Solution Step This Question"></div>');
$("div.answer_steps").append('<div id="answer_step_description' + answer_identifier_number + '" class = "answer_step_description" contenteditable="true" placeholder="Enter A Description as to how this step was reached or how to solve the next step"></div>');
$("div.answer_steps").append('<button id="remove_answer_step_button' + answer_identifier_number + '" class = "remove_answer_step_button">- Remove This Step</button>');
answer_identifier_number++;
});
});
</script>
Allow the divs to be draggable
<script type = "text/javascript" language = "javascript">
$(function() {
$( "#answer_steps" ).sortable();
$( "#answer_steps" ).disableSelection();
cursor: move;
});
</script>
I haven't figured out how to reindex the names yet but I have experience of that part so I should be fine. Thanks for your help.
ok, before you go tearing your hair out, have a look at this 'drag and drop' fiddle - its a heres-one-I made-earlier one jsfiddle.net/RachGal/ahnx7kwc It'll give you an idea about how the whole drag and drop thing works – Rachel Gallen 2 days ago
