Question

我有一个带有以下代码的JSP，它接受用户输入日期，然后搜索汽车：

<html>
<head> 
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />

    <title> iGo Rentals </title>

    </div>  
</div>
<div id="map_canvas"></div>
<script type="text/javascript">
    window.onload=checkCookies; 
</script>
</body>

完成汽车搜索后，我调用函数getTrailMap（）在页面上制作一个简单的地图。：

function getTrailMap() {    
    if (GBrowserIsCompatible()) {
        // position Map on home.jsp
        var map = new GMap2(document.getElementById("map_canvas") );

        map.addControl(new GLargeMapControl());
        //map.addControl(new GSmallMapControl());
        //map.addControl(new GMapTypeControl());
        map.setCenter(new GLatLng(43.785362,-79.185649), 10);
        //map.enableScrollWheelZoom();
    }
}

然而，这表现得很有趣，并且在我的“map_canvas”中给了我一个分裂的方形图（其他单词中的Tiles）而不是完整的地图。我尝试了完全相同的东西，但有一个没有任何东西的jsp除了javascript google key include和map_canvas div，它工作正常

有人请帮忙！可能是因为我包括的其他图书馆？

Answer 1

奥莱特！女士们，先生们，我花了很长时间来调试这个问题，秘诀就是显示的Gmap（或者像

那样返回的）

var map = new GMap2(document.getElementById("map_canvas") );

返回＆lt;的集合img＆gt;标签（如果你使用Firebug检查地图，你会看到它。）

问题是在我的css文件中的某个地方，我正在为＆lt;指定css。 IMG＆GT;标签（当然我在创建css的时候并不知道它，因为那时我的页面上有其他图像标签）。然而，这个css导致＆lt; img＆gt; GMap返回的标签缩小，因此我的问题！

Gmap无法在JSP上正确显示
