在使文本 DIV 可编辑时,我使用 setEndOfContenteditable 函数将光标置于文本末尾。
//Insert cursor at end of contentEditable element
function setEndOfContenteditable(contentEditableElement)
{
var range,selection;
if(document.createRange)//Firefox, Chrome, Opera, Safari, IE 9+
{
range = document.createRange();//Create a range (a range is a like the selection but invisible)
range.selectNodeContents(contentEditableElement);//Select the entire contents of the element with the range
range.collapse(false);//collapse the range to the end point. false means collapse to end rather than the start
selection = window.getSelection();//get the selection object (allows you to change selection)
selection.removeAllRanges();//remove any selections already made
selection.addRange(range);//make the range you have just created the visible selection
}
else if(document.selection)//IE 8 and lower
{
range = document.body.createTextRange();//Create a range (a range is a like the selection but invisible)
range.moveToElementText(contentEditableElement);//Select the entire contents of the element with the range
range.collapse(false);//collapse the range to the end point. false means collapse to end rather than the start
range.select();//Select the range (make it the visible selection
}
}
当我以前只有一个 div 和其中的文本时,这将完美地工作:
setEndOfContenteditable(curObj);
curObj 是其中包含文本的 DIV。
现在我已经切换到一个设计,我仍然有 curObj -div 但只是作为一个框架,包含实际文本的 DIV 位于其中。通常我这样做是为了达到(选择)我的 jQuery 代码中的内部 div
var curObj = window.curObj;
var inner = '#' + $(curObj).attr("id") + ' .object_inner';
$(inner).doAllMyStuff;
但是,这不适用于这个特定的 setEndOfContenteditable 函数,我得到的错误是
Uncaught Error: NotFoundError: DOM Exception 8
以及 setEndOfContenteditable 函数第 7 行的错误点:
range.selectNodeContents(contentEditableElement);//Select the entire contents of the element with the range
