删除内容后如何键入文本 [英] How can I type text after dropped content
本文介绍了删除内容后如何键入文本的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我正在使用jQuery UI可拖动组件来添加可编辑的内容
I'm using jQuery UI draggable component to add to content editable
.此代码可以找到，并且我没有什么问题.问题是当我将可拖动组件作为该段落的最后一个单词放置时.我无法在该删除的组件后面输入文本.
.This code works to find and I have little issues. The problem is when I dropped the draggable component as the last word of the paragraph. I cannot type text after that dropped component.
第二个问题是，我需要禁用单词的contentEditable选项(带有可移动选项的跨度)，以实现在$("p.given").blur事件中添加此代码($('.b').attr('contentEditable', false);).它工作正常.页面加载时，我需要做同样的事情.我该怎么做?我可以添加仅具有removeble选项的contentEditable = false属性.
and the second issue is, I need to disable contentEditable option from words (span with removable option), to achieve that I add this code ($('.b').attr('contentEditable', false);) inside $("p.given").blur event. It works fine. I need to do the same thing when the page load. how can I do it? can I add contentEditable = false attribute to which only have removeble option.
注意:当前功能不能中断.
Note: the current functionalities cannot be a break.

推荐答案
问题1
要允许在放置的元素后键入文本，请更改以下行:
Issue 1
To allow typing text after the dropped element, change this line:
return words.join(" ");
收件人:
return words.join(" ") + " ";
您甚至可以添加多个空格，例如+ " "，这将使查找插入符的位置更加容易.
You may even add multiple spaces, like + " " which would make it even easier to find the spot where the caret can be put.
在页面加载时将contenteditable = false应用于文本中已经存在的按钮"，添加您已在加载脚本中使用的行，例如在此行之后:
The apply contenteditable = false to the "buttons" already present in the text when the page loads, add the line you already use in the load script, for instance after this line:
$("p.given").html(chunkWords($("p.given").text()));
...因此它变成:
$("p.given").html(chunkWords($("p.given").text()));
$('span.b').attr('contentEditable', false);
其他建议
当将鼠标悬停在可编辑段落上时，我发现光标是指针令人困惑.我建议从p.given的CSS规范中删除此行:
Additional suggestion
I find it confusing that the cursor is a pointer when hovering over the editable paragraph. I would suggest removing this line from the CSS specs for p.given:
cursor: pointer !important;
我将添加此CSS定义，因此，当您将鼠标悬停在按钮"上时，会有一个游标差异:
And I would add this CSS definition, so there is a cursor difference when you hover over a "button":
p.given span.b {
cursor: default;
}
