replace（）标记在javascript中不起作用

I have database, that currently use inline edit in tables First problem was with paste of formatted text, but seems, that problem was fixed at 90% with this script:

<script type="text/javascript">

                var _onPaste_StripFormatting_IEPaste = false;

                function OnPaste_StripFormatting(elem, e) {

                    if (e.originalEvent && e.originalEvent.clipboardData && e.originalEvent.clipboardData.getData) {
                        e.preventDefault();
                        var text = e.originalEvent.clipboardData.getData('text/plain');
                        window.document.execCommand('insertText', false, text);
                    }
                    else if (e.clipboardData && e.clipboardData.getData) {
                        e.preventDefault();
                        var text = e.clipboardData.getData('text/plain');
                        window.document.execCommand('insertText', false, text);
                    }
                    else if (window.clipboardData && window.clipboardData.getData) {
                        // Stop stack overflow
                        if (!_onPaste_StripFormatting_IEPaste) {
                            _onPaste_StripFormatting_IEPaste = true;
                            e.preventDefault();
                            window.document.execCommand('ms-pasteTextOnly', false);
                        }
                        _onPaste_StripFormatting_IEPaste = false;
                    }

                }

    </script>

My php code look like this:

<td contenteditable='true' onblur=saveToDatabase(this,'titleeng','".$data['id']."') onClick='showEdit(this);' onpaste='OnPaste_StripFormatting(this, event);'>".$data['titleeng']."</td>

The script removes the tags, but leaves the   , that causing my sql ajax to failure

Here is Ajax script:

<script>
        function showEdit(editableObj) {
            $(editableObj).css("background","#FFF");
        } 

        function saveToDatabase(editableObj,column,id) {
            $(editableObj).css("background","#12ff65 url(loaderIcon.gif) no-repeat right");
            $.ajax({
                url: "saveedit.php",
                type: "POST",
                data:"column="+column+"&editval="+editableObj.innerHTML+"&id="+id,
                success: function(data){
                    $(editableObj).css("background","#FDFDFD");
                }        
           });
        }
        </script>

I am trying this: New components are text = text.replace("&nbsp"," ");

var _onPaste_StripFormatting_IEPaste = false;

                function OnPaste_StripFormatting(elem, e) {

                    if (e.originalEvent && e.originalEvent.clipboardData && e.originalEvent.clipboardData.getData) {
                        e.preventDefault();
                        var text = e.originalEvent.clipboardData.getData('text/plain');
                        string text = text;
                        text = text.replace("&nbsp"," ");
                        window.document.execCommand('insertText', false, text);
                    }
                    else if (e.clipboardData && e.clipboardData.getData) {
                        e.preventDefault();
                        var text = e.clipboardData.getData('text/plain');
                        string text = text;
                        text = text.replace("&nbsp"," ");
                        window.document.execCommand('insertText', false, text);
                    }
                    else if (window.clipboardData && window.clipboardData.getData) {
                        // Stop stack overflow
                        if (!_onPaste_StripFormatting_IEPaste) {
                            _onPaste_StripFormatting_IEPaste = true;
                            e.preventDefault();
                            window.document.execCommand('ms-pasteTextOnly', false);
                        }
                        _onPaste_StripFormatting_IEPaste = false;
                    }

                }

But nothing

The script removes the tags, but leaves the   , that causing my sql ajax to failure

That‘s because you neglected to URL-encode the parameter values you insert into the query string properly.

Use encodeURIComponent on the values before.

finally problem was with encoding as CBroe says

here is the ajax, that make it work

function saveToDatabase(editableObj,column,id) {
            $(editableObj).css("background","#12ff65 url(loaderIcon.gif) no-repeat right");
            var editxx = encodeURIComponent(editableObj.innerHTML);
            $.ajax({
                url: "saveedit.php",
                type: "POST",
                data:"column="+column+"&editval="+editxx+"&id="+id,
                success: function(data){
                    $(editableObj).css("background","#FDFDFD");
                }        
           });
        }
