This method is feasible.

With the above we can move the cursor in the div to the last face.

A complete example

The code is as follows

Copy Code

<button type= "button" onclick= "document.getElementById (' Test '). focus (); Inserthtmlatcaret (' <b>INSERTED</b> '); " > Insert Character </button> <div contenteditable= "true" style= "height:50px; border:2px solid red; "id=" Test ">&nbsp;</div> function Inserthtmlatcaret (HTML) { var sel, Range; if (window.getselection) { IE9 and Non-ie sel = Window.getselection (); if (sel.getrangeat && sel.rangecount) { Range = sel.getrangeat (0); Range.deletecontents (); Range.createcontextualfragment () would be useful Non-standard and not supported in all browsers (IE9, for one) var el = document.createelement ("div"); el.innerhtml = html; var frag = document.createdocumentfragment (), node, lastnode; while ((node = el.firstchild)) { Lastnode = frag.appendchild (node); } Range.insertnode (Frag); Preserve the selection if (lastnode) { Range = Range.clonerange (); Range.setstartafter (Lastnode); Range.collapse (TRUE); Sel.removeallranges (); Sel.addrange (range); } } } else if (document.selection && document.selection.type! = "Control") { IE < 9 Document.selection.createRange (). pastehtml (HTML); } }
