Since you have 5 elements with contenteditable, try giving them IDs to simplify access.

由于您有 5 个元素contenteditable，请尝试为它们提供 ID 以简化访问。

The following code deactivates the 5 contentediableelements:

以下代码停用 5 个contentediable元素：

var editable_elements = document.querySelectorAll("[contenteditable=true]");
editable_elements[0].setAttribute("contenteditable", false);
editable_elements[1].setAttribute("contenteditable", false);
editable_elements[2].setAttribute("contenteditable", false);
editable_elements[3].setAttribute("contenteditable", false);
editable_elements[4].setAttribute("contenteditable", false);

Demo

演示

Or you can you a loop

或者你可以循环

var editable_elements = document.querySelectorAll("[contenteditable=true]");
for(var i=0; i<editable_elements.length; i++)
    editable_elements[i].setAttribute("contenteditable", false);

Even though you not tagged this question as jquery, you already asked if there is a way to do it. and my way to do it is using jquery.

即使您没有将此问题标记为 jquery，您也已经询问是否有办法做到这一点。我的方法是使用 jquery。

Here's the FIDDLE

这是小提琴

$('div').blur(function () {
    $(this).attr('contenteditable', false);
});

or after saving the div content to db. use this code below to edit all div with contenteditable attribute true to false.

或者在将 div 内容保存到 db 之后。使用下面的代码来编辑所有具有 contenteditable 属性 true 为 false 的 div。

Heres' the FIDDLE

这是小提琴

$('div[contenteditable="true"]').attr('contenteditable', false);

To do it on each elements with "contenteditable=true" you can simple try this:

要使用“contenteditable=true”对每个元素执行此操作，您可以简单地尝试以下操作：

var editableElements = document.querySelectorAll("[contenteditable=true]");

for (var i = 0; i < editableElements.length; ++i) {
    editableElements[i].setAttribute("contentEditable", false);
}

Ming,

明，

You can use a Submit button at the end of your Div. So when the user is done with editing he can submit the form, you can do a post to save this text in database and also the button will make the content non-editable. Here I added a button to your code and a bit of jQuery.

您可以在Div. 因此，当用户完成编辑后，他可以提交表单，您可以发布帖子将此文本保存在数据库中，并且该按钮将使内容不可编辑。在这里，我在您的代码中添加了一个按钮和一些 jQuery。

<div class="date1" style="font-size: 38px; margin-top: 20px;">FOR A RIDE OF YOUR LIFE TIME</div>
<button text="Submit">Submit</button>

jQuery(just include a jquery file to your code)

jQuery（只需在代码中包含一个 jquery 文件）

$(function(){
    $('button').click(function(){
        $('div').attr('contenteditable', 'false');
    });
});

Thats it !!!

就是这样 ！！！
