如何使用“contenteditable 1”的val用“keyup”事件更新“contenteditable 2”？

I am struggling to achieve a solution to my problem:

我正在努力解决我的问题:

<div id="editable-content">
<span id="static1" class="non-editable">1-800-</span>
<span class="edittext" id="block1" class="editable" placeholder="HELLO" contenteditable="true"autofocus></span>

<div id="editable-content">
<span id="static2" class="non-editable">1-800-</span>
<span class="edittext" id="block2" class="editable" placeholder="HELLO" contenteditable="true"autofocus></span>

I want to use the value of #block1 to update #block2 on a keyup event. Means: As soon as user types into #block1 the same text simultaneously appears in #block2.

我想使用#block1的值来更新keyup事件中的#block2。意思是:只要用户输入#block1,同一文本就会同时出现在#block2中。

This my JS so far but it doesn't do what i want it to do:

这是我的JS到目前为止,但它没有做我想要它做的事情:

$( function() {
function updateTextarea() {
    $( '#block2' ).val( $( '#block1' ).val());
}
$( '#block1' ).keyup( updateTextarea );

});

What do I do wrong? Thank you so much in advance!!

我做错了什么?非常感谢你提前!!

#1

change this line:

改变这一行:

$( '#block2' ).text( $( '#block1' ).text());

Only form elements does have the value attribute so that can be get via .value from javascript or .val() method of jQuery.

只有表单元素确实具有value属性,因此可以通过jQuery的javascript或.val()方法获取.value。

Although contenteditable attribute lets you enter text in the element but that is just textContent of that element not value.

虽然contenteditable属性允许您在元素中输入文本,但这只是该元素的textContent而不是值。
