怎么做<li>点击后可编辑？

Question

I have a menu that looks like this:

I want to make it possible that when the user clicks on + the <li> element that it's located inside becomes like an editable input form, where a new menu item name can be created and saved (by entering the name and clicking Enter).

The code of the current item is

<li id="addNewContext" class="menu-item-divided"><a href="javascript:">+</a></li>

Is there a snippet of code I could use to make that field editable that could save the name entered into an array, which I can then use to repopulate the menu?

Thanks!

Answer 1

HTML5 allows for a ContentEditable attribute to be added to any HTML element. Assign a function to the onclick event for the list item, and make it set the ContentEditable attribute to true.

https://developer.mozilla.org/en-US/docs/Web/Guide/HTML/Content_Editable

 var list = document.querySelector('ul'); var editList = document.querySelector('.edit-list'); editList.onclick = function() { //or you can use list.setAttribute("contentEditable", true); list.contentEditable = true; }

 <ul> <li>list item</li> <li>List item</li> <li>List item</li> <li>List item</li> <li>List item</li> <li><span class="edit-list">+</span> </li> </ul>

I want to make it possible that when the user clicks on + the <li> element that it's located inside becomes like an editable input form, where a new menu item name can be created and saved (by entering the name and clicking Enter).

This sample also remove + sign on click:

 $('#addNewContext') // on click, make content editable. .click(function() { $(this).html("").attr('contenteditable', 'true'); }) // on hit enter, .keyup(function(e) { if (e.keyCode == 13) { var val = $(this).text(); $(this) // create a new li item .before("<li>" + val + "</li>") // set plus sign again .html("+") // make contenteditable to false, when clicked the process start again. .attr('contenteditable', 'false'); e.preventDefault(); } });

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <ul> <li>not edit me</li> <li>not edit me</li> <li>not edit me</li> <li>not edit me</li> <li id="addNewContext" class="menu-item-divided">+</li> </ul>

You can use contentEditable

 let list_1_e = document.getElementById('addNewContext'); list_1_e.contentEditable = true;
