I want a form that gives user the ability to dynamically add fields. What I need is the ability to add dynamic children and giving every child the ability to add its N number of children. Much like this
Parent 1
-- Child 1-1
-- Child 1-2
-- Child 1-2-1
-- Child 1-2-2
-- Child 1-2-3
-- Child 1-2-4
-- Child 1-2-4-1
-- Child 1-2-4-2
-- Child 1-3
-- Child 1-4
-- Child 1-5
-- Child 1-5-1
Parent 2
Parent 3
-- Child 3-1
Everything is dynamic, and a user can go as deep as they want to. So far, I'm able to achieve something similar to the JsFiddle link and I'm stuck badly after going 2 levels deep. PS: The numbers are added to show the relationship between a child to its siblings, its parent, and its children. Update 1: This is what I've been able to achieve so far: JsFiddle
Update 2: Did some more work on this and was able to get it this far: jsFiddle
I wouldn't use the onclick attributes in html, but add the event handlers with javascrip
if your child nodes all use the same code, you could try to use a recursive approach:
function spawn(event) {
$(this).append(child);
$(child).on('click', function(event) {spawn(event);});
}
$('.parent').on('click', function(event) {spawn(event);});
was a first idea (with jquery), maybe it inspires you.
ps lacking the rep to make this comment, so it's an answer instead >.>
Based on the user3154108's answer, here's a recursive solution, you can start with:
$('.parent').on('click', spawn);
function spawn(){
var x = $('<input class="' + this.className + '-child" type="button" value="Add Navigation" />');
x.on('click', spawn);
x.insertAfter(this);
}
as discussed, i have worked it out on the fiddle .
please use the wrapElement()
function to wrap your element in a div to your desire. In case you're loosing the fiddle, here's the code
$('.level_1').on('click', spawn);
function spawn(){
// check level
var level = stripLevel(this.className);
if (level !== '') {
var countOthers = this.parentNode.querySelectorAll("[class^='level_" + level +"']").length;
var x = wrapElement(level, countOthers);
if (level.length == 1) {
$('#addedElements').append(x);
} else {
//x.insertAfter(this);
$(this).parent().append(x);
}
}
}
// strip level
var stripLevel = function(className) {
var index = className.indexOf('_');
if(index > -1) {
return className.substr(index + 1);
} else {
return '';
}
}
// wrapper element
var wrapElement = function(level, number) {
var div = $('<div></div>');
if (level.length == 1) {
// it's parent
var input = $('<input type="text" name="foo_" />');
div.append(input);
} else {
// it's child
var span = $('<span>child level ' + level + '-' + number + '</span>');
div.append(span);
}
// add button
var button = $('<input class="level_' + level + '-' + number + '" type="button" value="Add Navigation" />');
button.on('click', spawn);
div.append(button);
div.css('margin-left', (level.length * 10) + 'px');
return div;
}
