javascript execCommand('delete')不会删除Chrome中的所有选择div [英] javascript execCommand('delete') not delete all selection div in chrome
问题描述
我尝试编写一个具有contenteditable& execCommand 在Firefox上一切正常，但是在chrome中，删除"命令存在错误.
I try to write an editor with contenteditable & execCommand Everything works fine on Firefox, but in chrome has an error with 'delete' command.
请查看下面的照片:
这是我的代码:
var $obj = $('#myBlockDivId');
var selection = rangy.getSelection();
if (selection.rangeCount > 0) selection.removeAllRanges();
var range = rangy.createRange();
range.selectNode($obj[0]);
selection.addRange(range);
range.select();
当我控制台日志时:rangy.getSelection().toHtml()==>是正确的
when i console log: rangy.getSelection().toHtml() ==> it's right
但是当我打电话时:
document.execCommand("delete", null, false);
在Firefox上很好，但在Chrome上不合适，包装器div不会被删除.
it's fine on Firefox but not right on Chrome, the wrapper div is not being deleted.
我该如何解决?我必须使用execCommand，因为它支持撤消和重做功能.因此，我无法使用jquery或javascript dom选择器删除div.
How can i fix this? I have to use execCommand because it's support undo and redo function. so, i can't use jquery or javascript dom selector to remove div.

推荐答案
也许您可以尝试做:
(仅注意论点)
Maybe you can try to do :
(note the argument alone)
<span contentEditable>
Select something here and after click on delete.
</span>
<input type="button" value="Delete selection" onclick="document.execCommand('delete')"/>
根据已启用的命令上的w3c.github.io :
Acording to w3c.github.io on Enabled commands :
在任何给定时间，可以启用或不启用受支持的命令.作者可以使用queryCommandEnabled()判断当前是否启用了命令. 未启用的命令不执行任何操作 ，如调用命令的各种方法的定义所述.
At any given time, a supported command can be either enabled or not. Authors can tell whether a command is currently enabled using queryCommandEnabled(). Commands that are not enabled do nothing, as described in the definitions of the various methods that invoke commands.
