方案一:

<code class="language-javascript">$.ajax({
    url: '/ashx/ajax.ashx',
    type: 'post',
    data: 'option=delete&name=11&adb, success: function (data) { if (data != 'error ') { } } }); '</code>
Copy after login

上面执行的ajax就是异步删除一个name为 11&abd 的数据 当请求到ajax.ashx页面时,我们获取到的name参数为11 执行操作后会发现其实删除了name 为 11的数据,而没有删除 name 为 11&abc 的数据 这是由于有&特殊字符,把以前的俩个参数变成了三个参数 option,name,abc 这时就需要用另外一种方法传递参数:

<code class="language-javascript">$.ajax({
    url: '/ashx/ajax.ashx',
    type: 'post',
    data: {
        'option': 'delete',
        'name': '11&adb'
    },
    success: function(data) {
        if (data != 'error') {}
    }
});</code>
Copy after login

采用上面的json格式传递参数就可以避免特殊字符引起的参数错误问题.

 

方案二: 统一编码UTF-8.

1.JSP页面:

<code class="language-xml"></code>
Copy after login

2.Ajax.js页面:传递参数时,可能出现特殊字符的参数用 escape(encodeURIComponent())两函数进行转码,传递到后台!

<code class="language-javascript">var url = "/ZX/servlet/AddMemoServlet memo=" + memoCode + "&otherMemo=" + escape(encodeURIComponent(otherMemo)) + "&applNo=" + applNo.innerText.substr(0, 16); //alert("url="+url); 
xmlHttp.open("POST", url, true); 
xmlHttp.onreadystatechange = doMemo; 
xmlHttp.send(null); </code>
Copy after login

3.服务器端接收传递的数据 比如:一个servlet的doGet方法中: request.setCharacterEncoding("gb2312"); response.setContentType("text/xml;charset=utf-8"); response.setHeader("Cache-Control", "no-cache"); ...... //以下解决Ajax中url传递的参数值中包含特殊字符,后端解析出错的问题:以utf-8以方式解码 java.net.URLDecoder urlDecoder=new java.net.URLDecoder(); String otherMemo = urlDecoder.decode(request.getParameter("otherMemo"),"utf-8"); logger.info("otherMemo:" + otherMemo);
