JavaScript Add/Remove sequential divs (add/remove/insert/re-order steps)
I currently have javascript/jquery to 'add and remove' steps from a set of instructions dynamically created in divs.
function add(){
var id = document.getElementById("hiddenCount").value;
$("#myId").append("<div id='step"+ 'id' + "...onclick='delete('"+id+")"...);
id = (id -1) + 2;
documen开发者_如何学Got.getElementById("hiddenCount").value = id;
}
function delete(id){
$("#" +id).remove();
document.getElementById("hiddenCount").value = (id-1);
}
This is great for adding and removing NON-sequenced/ordered ids, but if I want to insert a step in between 2 other steps or, remove several steps and then add, the numbering of ids becomes very unordered. Do you know of any javascript that handles situations like this, or should I use some other method to do this, like sortable values, or ordered lists?
The overall goal is to create a very easily editable way to add/remove/insert/re-order instructions dynamically with sequential div tags using jquery/javascript. In some cases the steps are pre-populated (from a database) and displayed, and will need to be edited. In some cases there are NO steps at all, but they need to create them.
I would suggest you use unordered lists, that way you can base the step's ordering not on their id's or something else, but on their index inside the parent ul
. If you'd like a code example I wouldn't mind writing one up.
