jsp：

 

<textarea name="content" id="content" cols="120" rows="4" style="overflow: auto;" 
class="validate[required,ajax[sensitiveWord]]"></textarea>

 

jquery.validationEngine-zh_CN.js：（Validation Engine 2.2.4 , jQuery plugin，2.2.4版本的 ）

 

"sensitiveWord":{
                	"url": "test!validateInfo.fhtm",
                	"extraDataDynamic": ['#content'],
                	"alertTextLoad": "验证中，请等待..."
                },

 

jquery.validationEngine.js: 需要修改以下的内容：

 

 _ajax: function(field, rules, i, options) {

            var errorSelector = rules[i + 1];
            var rule = options.allrules[errorSelector];
            var extraData = rule.extraData;
            var extraDataDynamic = rule.extraDataDynamic;

            if (!extraData)
                extraData = "";

            if (extraDataDynamic) {
              var tmpData = [];
              var domIds = String(extraDataDynamic).split(",");
              for (var i = 0; i < domIds.length; i++) {
                var id = domIds[i];
                if ($(id).length) {
                  var inputValue = field.closest("form").find(id).val();
                  var keyValue = id.replace('#', '') + '=' + 
                       encodeURIComponent(encodeURIComponent(inputValue));
                      //修改这里，原来的方法有点老，代码越界了，不需要换行
                  tmpData.push(keyValue);
                }
              }
              extraDataDynamic = tmpData.join("&");
            } else {
              extraDataDynamic = "";              
            }

 

java：

 

private String content;
private Object[] validateReturn = new Object[3];


....省略了get set方法.....


public void validateInfo() throws Exception{
		String result = "";
		validateReturn[0] = fieldId;
		validateReturn[1] = true;
		validateReturn[2] = "";	
		try{
			result = blacklistManager.getResult(URLDecoder.decode(content, "UTF-8"));	
		}
		catch (Exception e) {
			e.printStackTrace();
		}
		finally{
			if(StringUtils.isNotEmpty(result))
			{	
				validateReturn[0] = fieldId;
				validateReturn[1] = false;
				validateReturn[2] = "* 内容包含敏感字:"+result;
			}

			getResponse().setContentType("text/plain");
			PrintWriter out = getResponse().getWriter();
			JSONArray jsarry = new JSONArray();
			jsarry = JSONArray.fromObject(validateReturn);
			out.print(jsarry);
		}
		
	}

    public HttpServletResponse getResponse(){
		return  ServletActionContext.getResponse();
    }	
    
    public HttpServletRequest getRequest(){
		return  ServletActionContext.getRequest();
    }
