Google (Local) Search API的简单使用介绍

复制代码 代码如下:

function LocalSearchKeepHandler(result) {
  var from = document.getElementById("from");
  alert("result.tilte = " + result.title);
  from.value = ProcessString(result.title);
  alert("from.value = " + from.value);
 // alert(result.title);
 }

复制代码 代码如下:

google.load("search", "1", {"language": "zh-CN"});
 function initialize() {
     //LocalSearch Object used to create a local search service for the maps
        var localSearch = new google.search.LocalSearch(); 
        //restrict the local search resutls to kml and geocode results only, no business ones
        localSearch.setRestriction(google.search.Search.RESTRICT_TYPE, google.search.LocalSearch.TYPE_KMLONLY_RESULTS);            
        // Set the Local Search center point
  localSearch.setCenterPoint("北京"); 
  //It's about local search, which are used to set where the results will appear, a param of options
  var resultCanvas = document.getElementById("resultCanvas");      
  //options: open, alternate root
  var searcherOptions = new google.search.SearcherOptions();
  //show many results
  searcherOptions.setExpandMode(google.search.SearchControl.EXPAND_MODE_OPEN);
  //no results message
  searcherOptions.setNoResultsString(google.search.SearchControl.NO_RESULTS_DEFAULT_STRING);
  //options.setDrawMode(google.search.SearchControl.DRAW_MODE_TABBED);//web, local... in a tab show
  searcherOptions.setRoot(resultCanvas); //show the results in another place--<div id="resultCanvas">
     //SearchControl Object used to create a search service which will include a local search service                  
  var searchControl = new google.search.SearchControl(null);
  searchControl.addSearcher(localSearch, searcherOptions); 
  searchControl.addSearcher(new google.search.WebSearch());
  searchControl.addSearcher(new google.search.NewsSearch());
  searchControl.addSearcher(new google.search.BlogSearch());
  /https://img.qb5200.com/download-x/draw options and set it to a tabbed view,
  var drawOptions = new google.search.DrawOptions();
  drawOptions.setDrawMode(google.search.SearchControl.DRAW_MODE_TABBED)
  //make the searchControl return a result:GResult
  searchControl.setOnKeepCallback(this, LocalSearchKeepHandler);//keeping a search result
  //this option is used to set the search box position in a DOM tree.
  /https://img.qb5200.com/download-x/drawOptions.setSearchFormRoot(document.getElementById("drawOptions"));
  //set the input box to a user defined element 
  /https://img.qb5200.com/download-x/drawOptions.setInput(document.getElementById("input"));
  // tell the search box to draw itself and tell it where to attach
 // searchControl.draw(document.getElementById("searchBox"), drawOptions);//Here I changed fromaddress and toaddress to search, a new place
  //another user defined input box
  drawOptions.setInput(document.getElementById("input2"));
  searchControl.draw();
  /** The codes below is about google Ajax Map Search API
  //this code segment is used to add a sidebar to show the results of the search
  //I wonder why no 'var' exists here
   optinos = new Object();
   options.resultList = resultCanvas;
   options.resultFormat = "multi-line1";
   var lsc2 = new google.elements.LocalSearch(options);
   map.addControl(lsc2, new GControlPosition(G_ANCHOR_TOP_LEFT, new GSize(-282, -2)));

 google.setOnLoadCallback(initialize);
