纯javascript+xml配置验证

XML JavaScript QQ Web Microsoft

前两天无事写了个xml+javascript结合页面表单的实例,实际用起来不怎么方便,今天对它进行了改进,不管是从界面显示还是从代码较前好些.但是js加载xml时出现中文乱码,希望高手能提供好的解决办法.目前我只能用英文代替提示信息.

和前面一样xml中的id和表单的id要一样才行.

js代码:

var submitflag=false;
var xmlDoc=null;
function   getxmlDoc()   
  {   
      	  xmlDoc=new   ActiveXObject("Microsoft.XMLDOM");   
          xmlDoc.async=false;   
          xmlDoc.load("../web/js/validator.xml");   
          if(xmlDoc.parseError.errorCode!=0)   
          {   
                  var   myErr=xmlDoc.parseError;   
                  alert("出错！"+myErr.reason);   
          }           
  }

/**
	创建一个Div消息提示框
*/
function createDivMessage(e,strHtml){
	var div=document.getElementById("divMsg");
	if(div!=null){
		document.body.removeChild(div);
	}
	var object=e;
	var div=document.createElement('div');
	 	div.id="divMsg";
		div.style.position = "absolute";
		var ttop=object.offsetTop+object.offsetHeight;
		var tleft=object.offsetLeft+object.offsetWidth;
		while(object=object.offsetParent){ttop+=object.offsetTop;tleft+=object.offsetLeft;}
		div.style.top=ttop;
		div.style.left=tleft;
		div.style.width= 250;
		div.style.height=64;
		div.style.background="url(../web/images/userimages/message.PNG)";
		div.innerHTML=strHtml;
		document.body.appendChild(div);
}
window.onload=roadXml;

/**

*/
function roadXml(){
		getxmlDoc();
		var nodeList=xmlDoc.selectSingleNode("form").childNodes;
		var str="";
			for(var i=0;i<nodeList.length;i++){
				var id=nodeList[i].getAttribute('id');
				var startLength=nodeList[i].getAttribute('startLength');
				var lastLength=nodeList[i].getAttribute('lastLength');
				var expression=nodeList[i].getAttribute('expression');
				var errorNull=nodeList[i].getAttribute('errorNull');
				var errorFormat=nodeList[i].getAttribute('errorFormat');

				var trueMessage=nodeList[i].getAttribute('trueMessage');
				validatorMethod(id,startLength,lastLength,expression,errorNull,errorFormat,errorLength,trueMessage);
			}
			
}
window.setInterval("removeTag()",5000);

function removeTag(){
	var div=document.getElementById("divMsg");
	if(div!=null){
		document.body.removeChild(div);
	}else{
	
	}
}
/**

function validatorMethod(id,startLength,lastLength,expression,errorNull,errorFormat,errorLength,trueMessage){
		var object=document.getElementById(id);
		object.onblur = function(){
			var lengthFlag=validatorLength(object,startLength,lastLength);
			var formatFlag=validatorFormat(object,expression);
			var message="";
				
				switch(lengthFlag){
					case "0":message+="<font color='red'>"+errorNull;
							break;
					case "1":message+="<font color='red'>"+errorLength;
							break;
					case "2":
								if(formatFlag){
										message+="<font color='green'>"+trueMessage;
										submitflag=true;
								}else{
										message+="<font color='red'>"+errorFormat;
					
								}
							break;
					
				}
				createDivMessage(object,message);
		};
}
