あなたがやろうとしていることを私が見つけたとしても、あなたが想像するほど実現可能ではありません。ただし、コツがあります。以下はその一つです。アイデアは、スパンがある場所に「非表示の」入力を挿入し、必要に応じて入力を表示してスパンを非表示にする関数を作成することです(ユーザーがスパンをクリックしたときなど)。
HTML
<button id="createDiv">Start</button>
<div id="results"></div>
CSS
#createDiv, #results span { cursor: pointer; }
#results div {
background: #FFA;
border: 1px solid;
margin: 1em;
padding: 1em 1em 2em;
}
#results input[type=text] {
border: none;
display: none;
outline: none;
}
JavaScript
// Call for document .onload event
$(function() {
// Normal Click event asignement, same as $("#createDiv").click(function
$("#createDiv").on("click", function(e) {
// Simply creating the elements one by one to remove confusion
var newDiv = $("<div />", { class: "new-folder" }), // Notice, each child variable is appended to parent
newInp = $("<input />", { type: "text", value: "New Folder", class: "title-inp" }).appendTo(newDiv),
newSpan = $("<span />", { id: "myInstance2", text: "New Folder", class: "title-span" }).appendTo(newDiv);
// Everything created and seated, let's append this new div to it's parent
$("#results").append(newDiv);
});
// the following use the ".delegate" side of .on
// This means that ALL future created elements with the same classname,
// inside the same parent will have this same event function added
$("#results").on("click", ".new-folder .title-span", function(e) {
// This hides our span as it was clicked on and shows our trick input,
// also places focus on input
$(this).hide().prev().show().focus();
});
$("#results").on("blur", ".new-folder .title-inp", function(e) {
// tells the browser, when user clicks away from input, hide input and show span
// also replaces text in span with new text in input
$(this).hide().next().text($(this).val()).show();
});
// The following sures we get the same functionality from blur on Enter key being pressed
$("#results").on("keyup", ".new-folder .title-inp", function(e) {
// Here we grab the key code for the "Enter" key
var eKey = e.which || e.keyCode;
if (eKey == 13) { // if enter key was pressed then hide input, show span, replace text
$(this).hide().next().text($(this).val()).show();
}
});
})
