requestwrapper.js

google的search的api 以及其demo 使用ajax的 dwr+prototype技术实现

var requestWrapper=Class.create();
requestWrapper.prototype={
	href:'',
	request:null,
	reqW_Self:null,
	initialize:function(href){
		reqW_Self=this;
		var urlStr=href;
		reqW_Self.href=href;
//		alert(urlStr.indexOf("?"));
		reqW_Self.request = new Object();
		if(urlStr.indexOf("?")!=-1) {
			var paramStr = urlStr.substr(urlStr.indexOf("?")+1);
			paramStrs = paramStr.split("&");
			for(var i=0;i<paramStrs.length;i++) {
				reqW_Self.request[paramStrs[i].split("=")[0]]=unescape(paramStrs[i].split("=")[1]);
				//alert(paramStrs[i].split("=")[0]+":"+paramStrs[i].split("=")[1]);
			}
		}
	},
	getParamValue:function(paramName){
		if (reqW_Self.request[paramName]){
			return reqW_Self.request[paramName];
		}
		else{
			return null;
		}
	}
}
