在新窗口中打开动态构建的 Google URL

Question

我正在使用最初由 Google 提供的修改后的代码来制作使用 Google 地图的公交旅行计划表。我希望结果在新窗口/选项卡中打开，这样用户就不必离开网站（我意识到这是一个有争议的可用性问题，但这是我客户的要求，所以......）。

下面的代码在标签中使用 target="_blank" - 这似乎是最简单的解决方案 - 但在这种情况下不起作用 - 不知道为什么，但认为它可能与动态构建有关网址。

我尝试了从该站点上以前类似问题中收集的几种方法，下面的方法是其中之一，以及类似于

的方法

myForm.setAttribute("target", "_blank");

但到目前为止还没有成功。

这是我正在使用的代码。任何建议将不胜感激。

     <script language="JavaScript" type="text/javascript">
 // Edit the strings below this line
 var startExample = "USC";
 var endExample = "201 N Los Angeles St.";
 var zip = "90012";
 // End edit block

 // Get and parse the user's current date/time
 var date = new Date();
 var isPM = false;
 var currentTime = date.getHours();
 var currentDate = "";
 var amOption = '<option value="am">AM';
 var pmOption = '<option value="pm">PM';

 if(currentTime > 11)
 isPM = true;
 currentTime %= 12;
 if(currentTime == 0)
 currentTime = 12;

 currentTime += ':';
 if(date.getMinutes() < 10)
 currentTime += '0';
 currentTime += date.getMinutes();

 if(isPM)
 pmOption = '<option selected="true" value="pm">PM';
 else
 amOption = '<option selected="true" value="am">AM';

 if(date.getMonth() < 9)
 currentDate = '0';
 currentDate += (date.getMonth() + 1) + '/';
 if(date.getDate() < 10)
 currentDate += '0';
 currentDate += date.getDate() + '/' + date.getFullYear();

 // Builds the destination URL
 function buildURL() {
 var loc = 'http://www.google.com/maps?ie=UTF8&f=d&';

 for (var i = 0; (i < document.myForm.length - 1); i++) {
 if(document.myForm[i].name == 'ampm')
 continue;
 if(document.myForm[i].name == 'time')
 loc += document.myForm[i].name + '=' + document.myForm[i].value + document.myForm.ampm.value + '&';
 else {
 if(document.myForm[i].name == 'saddr')
 loc += document.myForm[i].name + '=' + document.myForm[i].value + '+near+' + zip + '&';
 else
 loc += document.myForm[i].name + '=' + document.myForm[i].value + '&';
 }
 }
 loc+='dirflg=r';


 location.href=loc;
 return true;


 }
</script>

Answer 1

您可以尝试改用window.open。这是我为打开子窗口创建的一个函数：

openChildWindowWithDimensions = function(url, width, height, showMenu, canResize, showScrollbars) {
    var childWindow = window.open(url, "", "\"width=" + width + ",height=" + height + ",menubar=" + (showMenu ? "1" : "0") + ",scrollbars=" + (showScrollbars ? "1" : "0") + ",resizable=" + (canResize ? "1" : "0") + "\"");
    if (childWindow){
        childWindow.resizeTo(width, height); //IE9 dimensions bug
    }
}

将此函数添加到您的页面，并在构建 URL 的函数的末尾，像这样调用它：

openChildWindowWithDimensions(loc, 800, 600, true, true, true);
