对于任何感兴趣的人，我把一个jQuery插件放在一起，它包含了toolman的(加上@MaffooClock/@cdmckay的评论)和@Vladimir Kornea的想法。

用法:

//# Disable backspace on .disabled/.readOnly fields for the whole document
$(document).disableBackspaceNavigation();

//# Disable backspace on .disabled/.readOnly fields under FORMs
$('FORM').disableBackspaceNavigation();

//# Disable backspace on .disabled/.readOnly fields under #myForm
$('#myForm').disableBackspaceNavigation();

//# Disable backspace on .disabled/.readOnly fields for the whole document with confirmation
$(document).disableBackspaceNavigation(true);

//# Disable backspace on .disabled/.readOnly fields for the whole document with all options
$(document).disableBackspaceNavigation({
    confirm: true,
    confirmString: "Are you sure you want to navigate away from this page?",
    excludeSelector: "input, select, textarea, [contenteditable='true']",
    includeSelector: ":checkbox, :radio, :submit"
});

插件:

//# Disables backspace initiated navigation, optionally with a confirm dialog
//#     From: https://stackoverflow.com/questions/1495219/how-can-i-prevent-the-backspace-key-from-navigating-back
$.fn.disableBackspaceNavigation = function (vOptions) {
    var bBackspaceWasPressed = false,
        o = $.extend({
            confirm: (vOptions === true),   //# If the caller passed in `true` rather than an Object, default .confirm accordingly,
            confirmString: "Are you sure you want to leave this page?",
            excludeSelector: "input, select, textarea, [contenteditable='true']",
            includeSelector: ":checkbox, :radio, :submit"
        }, vOptions)
    ;

    //# If we are supposed to use the bConfirmDialog, hook the beforeunload event
    if (o.confirm) {
        $(window).on('beforeunload', function () {
            if (bBackspaceWasPressed) {
                bBackspaceWasPressed = false;
                return o.confirmString;
            }
        });
    }

    //# Traverse the passed elements, then return them to the caller (enables chainability)
    return this.each(function () {
        //# Disable backspace on disabled/readonly fields
        $(this).bind("keydown keypress", function (e) {
            var $target = $(e.target /*|| e.srcElement*/);

            //# If the backspace was pressed
            if (e.which === 8 /*|| e.keyCode === 8*/) {
                bBackspaceWasPressed = true;

                //# If we are not using the bConfirmDialog and this is not a typeable input (or a non-typeable input, or is .disabled or is .readOnly), .preventDefault
                if (!o.confirm && (
                    !$target.is(o.excludeSelector) ||
                    $target.is(o.includeSelector) ||
                    e.target.disabled ||
                    e.target.readOnly
                )) {
                    e.preventDefault();
                }
            }
        });
    });
}; //# $.fn.disableBackspaceNavigation

该解决方案在测试时工作得非常好。

我确实添加了一些代码来处理一些没有标记输入的输入字段，并集成到一个Oracle PL/SQL应用程序中，为我的工作生成一个输入表单。

我的“两分”:

 if (typeof window.event != ''undefined'')
    document.onkeydown = function() {
    //////////// IE //////////////
    var src = event.srcElement;
    var tag = src.tagName.toUpperCase();
    if (event.srcElement.tagName.toUpperCase() != "INPUT"
        && event.srcElement.tagName.toUpperCase() != "TEXTAREA"
        || src.readOnly || src.disabled 
        )
        return (event.keyCode != 8);
    if(src.type) {
       var type = ("" + src.type).toUpperCase();
       return type != "CHECKBOX" && type != "RADIO" && type != "BUTTON";
       }
   }
else
   document.onkeypress = function(e) {
   //////////// FireFox 
   var src = e.target;
   var tag = src.tagName.toUpperCase();
   if ( src.nodeName.toUpperCase() != "INPUT" && tag != "TEXTAREA"
      || src.readOnly || src.disabled )
      return (e.keyCode != 8);
    if(src.type) {
      var type = ("" + src.type).toUpperCase();
      return type != "CHECKBOX" && type != "RADIO" && type != "BUTTON";
      }                              
   }

Sitepoint:禁用Javascript

event.stopPropagation()和event.preventDefault()在IE中什么都不做。我必须发送返回事件。keyCode == 11(我只是选择了一些东西)，而不是只是说“如果不= 8，运行事件”，使其工作，尽管。事件。returnValue = false也适用。

修正的erikkallen回答:

$(document).unbind('keydown').bind('keydown', function (event) {

    var doPrevent = false, elem;

    if (event.keyCode === 8) {
        elem = event.srcElement || event.target;
        if( $(elem).is(':input') ) {
            doPrevent = elem.readOnly || elem.disabled;
        } else {
            doPrevent = true;
        }
    }

    if (doPrevent) {
        event.preventDefault();
        return false;
    }
});

停止导航此代码工作!

$(document).on("keydown", function (event) {        
   if (event.keyCode === 8) {
      event.preventDefault();
    }
  });

但不是限制文本框，而是其他的

$(document).on("keydown", function (event) {
  if (event.which === 8 && !$(event.target).is("input, textarea")) {
   event.preventDefault();
  }
});

为了防止它在特定领域简单使用

$('#myOtherField').on("keydown", function (event) {
  if (event.keyCode === 8 || event.which === 8) { 
   event.preventDefault(); 
  } 
});

参考下面这个!

用jQuery阻止BACKSPACE导航返回(像谷歌的主页)

另一个使用jquery的方法

    <script type="text/javascript">

    //set this variable according to the need within the page
    var BACKSPACE_NAV_DISABLED = true;

    function fnPreventBackspace(event){if (BACKSPACE_NAV_DISABLED && event.keyCode == 8) {return false;}}
    function fnPreventBackspacePropagation(event){if(BACKSPACE_NAV_DISABLED && event.keyCode == 8){event.stopPropagation();}return true;}

    $(document).ready(function(){ 
        if(BACKSPACE_NAV_DISABLED){
            //for IE use keydown, for Mozilla keypress  
            //as described in scr: http://www.codeproject.com/KB/scripting/PreventDropdownBackSpace.aspx
            $(document).keypress(fnPreventBackspace);
            $(document).keydown(fnPreventBackspace);

            //Allow Backspace is the following controls 
            var jCtrl = null;
            jCtrl = $('input[type="text"]');
            jCtrl.keypress(fnPreventBackspacePropagation);
            jCtrl.keydown(fnPreventBackspacePropagation);

            jCtrl = $('input[type="password"]');
            jCtrl.keypress(fnPreventBackspacePropagation);
            jCtrl.keydown(fnPreventBackspacePropagation);

            jCtrl = $('textarea');
            jCtrl.keypress(fnPreventBackspacePropagation);
            jCtrl.keydown(fnPreventBackspacePropagation);

            //disable backspace for readonly and disabled
            jCtrl = $('input[type="text"][readonly="readonly"]')
            jCtrl.keypress(fnPreventBackspace);
            jCtrl.keydown(fnPreventBackspace);

            jCtrl = $('input[type="text"][disabled="disabled"]')
            jCtrl.keypress(fnPreventBackspace);
            jCtrl.keydown(fnPreventBackspace);
        }
    }); 

    </script>
