xmlhttprequest返回數據 url中文傳參

折騰了一上午，終於能用了

1.Defalut頁面js,點擊按鈕返回SearchResult.aspx中的數據，注意參數是中文，注意轉換var keyword=escape(key),

<mce:script type="text/javascript"><!-- var $=function(o){return document.getElementById(o);} var MyApp={ Open:function(method,url,fn){//T 方法GET POST U=URL FN backcall var Ajax=(window.XMLHttpRequest)? new XMLHttpRequest() : new ActiveXObject("Microsoft.XMLHTTP"),data; Ajax.open(method,url,true); Ajax.onreadystatechange=function(){if(Ajax.readyState==4){data=Ajax.responseText;fn(data);}}; Ajax.send(null) ; }, Data:function(data){ if(data.length>0){ $("divSearch").style.display='block'; $("divAll").style.display='none' ; $("divSearch").innerHTML="數據加載中....."; $("divSearch").innerHTML="<ul class=/"iss-list/">"+data+"</ul>"; } else { $("divSearch").style.display='none'; $("divAll").style.display='block' ; } } } window.οnlοad=function(){ $('btnSearch').οnclick=function(){ var key=document.getElementById("txtkeywork").value; var keyword=escape(key); if(key.length==0) { alert("請輸入搜索條件！"); return false; } else { MyApp.Open("get","SearchResult.aspx?KeyWord="+keyword+"",MyApp.Data); } } } // --></mce:script>

2.SearchResult.aspx頁面進行字符解析

      string key = Request.QueryString["KeyWord"];
       string word = Server.UrlDecode(key);

string key = Request.QueryString["KeyWord"]; string word = Server.UrlDecode(key); //string key = "充值"; if (!string.IsNullOrEmpty(word)) { string INDEX_STORE_PATH = Server.MapPath("/dex"); //INDEX_STORE_PATH 爲索引存儲目錄 string keyword = key; Hits myhit = null; //搜索全文 IndexSearcher mysea = new IndexSearcher(INDEX_STORE_PATH); String[] fields = { "FaqSubject", "FaqContent" }; QueryParser q = new MultiFieldQueryParser(fields, new StandardAnalyzer()); Query query = q.Parse(keyword); myhit = mysea.Search(query); //Tip = "關於：<font color='red'>" + keyword + "</font> 搜索到<font color='red'> " + myhit.Length() + " </font>個結果"; //高亮顯示 SimpleHTMLFormatter shtml = new SimpleHTMLFormatter("<font color='red'>", "</font>"); Highlighter highlighter = new Highlighter(shtml, new QueryScorer(query)); if (myhit != null) { if (myhit.Length() > 0) { string tt = string.Empty; for (int i = 0; i < myhit.Length(); i++) { Document doc = myhit.Doc(i); //myrow = mytab.NewRow(); string title = doc.Get("FaqSubject").ToString(); string content = doc.Get("FaqContent").ToString(); //高亮顯示內容字數設置 highlighter.SetTextFragmenter(new SimpleFragmenter(content.Length)); Analyzer analyzer = new StandardAnalyzer(); TokenStream tokenStream = analyzer.TokenStream("FaqSubject", new System.IO.StringReader(title)); TokenStream contentStream = analyzer.TokenStream("FaqContent", new System.IO.StringReader(content)); string resultTitle = highlighter.GetBestFragment(tokenStream, title); string resultContent = highlighter.GetBestFragment(contentStream, content); if (string.IsNullOrEmpty(resultTitle)) { resultTitle = title; } if (string.IsNullOrEmpty(resultContent)) { resultContent = content; } tt += "<li class=/"faq_q/">" + resultTitle + "</li><li>" + resultContent + "</li>"; } Response.Write(tt.ToString()); } mysea.Close(); }
