Google Maps v3商店定位器问题

Question

我一直在使用Google Maps API v3来创建中心定位器，如本教程https://developers.google.com/maps/articles/phpsqlsearch_v3中所述。

我根据自己的需要对其进行了编辑，并在地图下方有一张表格，其中包含当地商店的详细信息。这适用于Chrome，Firefox和IE8，但我无法在IE7中使用它。我没有得到任何错误只是结果表根本不显示，任何人有任何想法？我使用IE浏览器javascript调试工具，数据似乎正在通过确定

这是JS

$(document).ready(function () {

$('form').after('<div id="map"></div>');
$('#map').after('<div id="directionsPanel"></div>');
$('#directionsPanel').after('<h3 id="local-centres">Your search results</h3>');

$('h3#local-centres').after('<table id="locationSelect"></table>');
var tableHeaders = '<ul class="col-titles"><li class="centre-title">Centre</li><li class="address-title">Address &amp Tel</li><li class="distance-title">Distance</li><li class="option-title">Options</li></ul>'

$('#directionsPanel').hide();
$('#directionsPanel').prepend('<h2>Directions by text - Driving</h2>');
$('#directionsPanel').before('<a href="#" class="print-locations" id="print-locations">Print text directions</a>');
$('a.print-locations').hide();

    var keynum; // establish variable to contain the value of the key that was pressed
    // now, set that variable equal to the key that was pressed
    if (window.event) // ID
    {
        keynum = e.keyCode;
    } else if (e.which) // other browsers

Answer 1

console.log（）将导致IE7出现问题，取出或注释掉所有控制台语句并再次尝试。没有多少答案，我在工作，只是刺伤这个，是完全ag'in'规则？我很确定你的其余代码是否正常，删除整个console.log（）语句将在IE 7中修复它。
