ajax实现的提交文章前进行敏感词审核的代码

<br><input type="button" class="body" id="subm" name="subm" value="写好了，发布出去" <br>onclick="chkfull(this)"/>//注意类型是“按钮” <br><input type="hidden" id="userchksense" name="userchksense" value="?"/>//嵌入一个隐藏的文本框，给Ajax传值 <br> <br>Ajax的Javascript部分 <br><span><u></u></span> 代码如下:<pre class="brush:php;toolbar:false layui-box layui-code-view layui-code-notepad"><ol class="layui-code-ol"><li><br>function chkfull(bt){ <br>var content = document.getElementById("usercontent").value; <br>if(content=="") <br>{ <br>    alert("正文为必填。");//判断文章内容是否为空 <br>    return false; <br><br>} <br>else <br>{ <br>    var xHRObject=false; <br><br>    if(window.XMLHttpRequest)//判断浏览器内核 <br>    { <br>        xHRObject=new XMLHttpRequest(); <br>    } <br>    else if(window.ActiveXObject) <br>    { <br>        xHRObject= new ActiveXObject("Microsoft.XMLHTTP"); <br>    } <br><br>    function get2()//定义get2函数，给onreadystatechange做准备。本函数不能放在xHRObject.onreadystatechange=get2;的后面 <br>    { <br>        if(xHRObject.readyState==4 && xHRObject.status==200) <br>        { <br>            var serverText=xHRObject.responseText; <br>            if(serverText=="sense") <br>            { <br>                if(confirm("你的文章有敏感词汇，确定要发布吗？\n\r【是，发布】将被审核，请等待。\n\r【否，不发布】将返回界面，请修改字句。")) <br>                { <br>                    bt.value="正在提交"; <br>                    bt.disabled=true;//关闭按钮 <br>                    document.getElementById("userchksense").value="sense";//改变userchksense的值为sense，这样，post到add.php就能直接检查是否要锁定本文，而不用再次检查文章 <br>                    document.form1.submit();//提交该表单 <br>                } <br>                else//好像有点多余，不过这样比较保险 <br>                return false; <br>            }     <br>            else <br>            { <br>                bt.value="正在提交"; <br>                bt.disabled=true; <br>                document.getElementById("userchksense").value="nonsense"; <br>                document.form1.submit(); <br>            } <br><br>        } <br>    } <br><br>     <br>    var title=document.getElementById("usertitle").value; <br>    var tag=document.getElementById("usertag").value; <br>    var intro=document.getElementById("userintro").value; <br>    var content=document.getElementById("usercontent").value; <br><br>     <br>    var v = "title="+title+"&tag="+tag+"&intro="+intro+"&content="+content; <br>    xHRObject.open("POST","../ajax/ajax.php",true);     <br>    xHRObject.setRequestHeader("Content-Type","application/x-www-form-urlencoded"); <br><br>    xHRObject.onreadystatechange=get2;//此处的get2不能打括号，否则是将函数的返回值赋值给一个变量，而不是将本函数本身赋值给xHRObject.onreadystatechange（注释1） <br>    xHRObject.send(v); <br>} <br><br>} <br></li><li>            </li><li>                                </li></ol></pre>
