问题描述

当我在jQuery选项卡中运行时,我无法运行Google地图。不知道这是为什么。

 < script type =text / javascript> 
$(document).ready(function(){
var map = null;
$(ul.css-tabs)。tabs(div.css-panes> div );
$(div.css-panes> div)bind('tabsshow',function(event,ui){
if(ui.panel.id =='map_tab' &&!map)
{
map = initialize();
google.maps.event.trigger(map,'resize');
}
});
});

函数initialize(){
var latlng = new google.maps.LatLng({latitude},{longitude});

var myOptions = {
zoom:8,
center:latlng,
mapTypeId:google.maps.MapTypeId.ROADMAP
};

var map = new google.maps.Map(document.getElementById(map_canvas),
myOptions);

var marker = new google.maps.Marker({
position:latlng,
map:map,
title:{CaveTitle}
});

返回地图;
};

//google.maps.event.addDomListener(window,'load',initialize);

< / script>

这是我的html

 < ul class =css-tabs> 
< li style =list-style-image:none;>< a href =#>信息< / a>< / li>
< li style =list-style-image:none;>< a href =#>描述< / a>< / li>
< li style =list-style-image:none;>< a href =#>地图< / a>< / li>
< li style =list-style-image:none;>< a href =#>图片< / a>< / li>
< / ul>
<! - 窗格 - >
< div class =css-panes>
< div>< p> {重要信息}< / p>< / div>
< div>< p> {description}< / p>< / div>
< div style =height:300px; ID = map_tab >
< p>经度:{经度}< br />
纬度:{latitude}< br />< / p>
< p>< div id =map_canvasstyle =width:500px; height:200px>< / div>< / p>
< / div>
< div>< p>
{start block images}
< a href =images / original / {image}class =thickbox>< img src =images / thumbnail / {image}width = 100alt ={title}/>< / a>
{end block images}
< / p>< / div>
< / div>

这里有一些CSS

  / *标签的根元素* / 
ul.css-tabs {
margin-left:10px;
padding:0;
height:30px;
width:750px;
border-bottom:1px solid#666;
}

/ *单个标签* /
ul.css-tabs li {
float:left;
padding:0;
list-style-type:none;
}

/ *链接。使用背景图片* /
ul.css-tabs a {
float:left;
font-size:13px;
display:block;
padding:5px 30px;
text-decoration:none;
border:1px solid#666;
border-bottom:0px;
height:18px;
颜色:#777;
margin-right:2px;
职位:亲属;
top:1px;
outline:0;
-moz-border-radius:4px 4px 0 0;
背景:#bbbbbb url(nav.jpg)repeat-x;
颜色:#FFF;
text-align:left;
white-space:nowrap;
}

ul.css-tabs a:hover {
background-color:#F7F7F7;
颜色:#333;
}

/ *选定标签* /
ul.css-tabs a.current {
background-color:#ddd;
border-bottom:1px solid #ddd;
颜色:#000;
cursor:default;
}


/ *制表符窗格* /
.css-panes div {
display:none;
border:1px solid#666;
border-width:0 1px 1px 1px;
min-height:800px;
padding:15px 20px;
background-color:#ddd;
margin-left:10px;
width:710px;
位置:绝对;剩余
:-1000px;


解决方案

感谢您的示例页面! !我看到的第一个错误是在你的CSS中。

  / *选项卡窗格* / 
.css-panes div {
display:none;
...
}

上面的代码片段用于隐藏没有被加载的css页面,但是它也覆盖并隐藏位于具有类.css-panes类的元素下的任何 div。在这种情况下, display:none; 正在map_canvas div上设置。这个选择其他元素,例如尺寸和着色信息,也混淆了Google Maps API绘制的所有div。你应该做一些不那么积极的事情,或者为每个窗格div添加一个窗格类并直接选择它。



清理完样式表后,我可以通过在JavaScript控制台中运行 initialize()函数来手动加载映射。它看起来像你的绑定/事件触发器代码没有按预期发射。我会添加一个简单的 console.log(Foo); 甚至是一个 alert(Test); 代替初始化方法调用来帮助调试tabshow事件。 (我没有运气让它工作,我也不是jQuery选项卡专家)

I can't get google maps running when beeing in a jQuery tab. Not sure why this is.

<script type="text/javascript">
$(document).ready(function() {
    var map = null;
    $("ul.css-tabs").tabs("div.css-panes > div");
    $("div.css-panes > div").bind('tabsshow', function(event, ui) {
        if (ui.panel.id == 'map_tab' && !map)
        {
            map = initialize();
            google.maps.event.trigger(map, 'resize');
        }
    });
});

  function initialize() {
    var latlng = new google.maps.LatLng({latitude},{longitude});

    var myOptions = {
      zoom: 8,
      center: latlng,
      mapTypeId: google.maps.MapTypeId.ROADMAP
    };

    var map = new google.maps.Map(document.getElementById("map_canvas"),
        myOptions);

    var marker = new google.maps.Marker({
      position: latlng,
      map: map,
      title:"{CaveTitle}"
    });

    return map;
  };

  //google.maps.event.addDomListener(window, 'load', initialize);

</script>

This is my html

<ul class="css-tabs">
    <li style="list-style-image: none;"><a href="#">Information</a></li>
    <li style="list-style-image: none;"><a href="#">Description</a></li>
    <li style="list-style-image: none;"><a href="#">Map</a></li>
    <li style="list-style-image: none;"><a href="#">Images</a></li>
</ul>
<!-- panes -->
<div class="css-panes">
    <div><p>{ImportantInfo}</p></div>
    <div><p>{description}</p></div>
    <div style="height:300px;" id="map_tab">
        <p>Longitude: {longitude}<br />
        Latitude: {latitude}<br /></p>
        <p><div id="map_canvas" style="width: 500px; height: 200px"></div></p>
    </div>
    <div><p>
    {start block images}
            <a href="images/original/{image}" class="thickbox"><img src="images/thumbnail/{image}" width="100" alt="{title}"/></a>
    {end block images}
        </p></div>
</div>

Here some CSS

/* root element for tabs  */
ul.css-tabs {  
    margin-left:10px; 
    padding:0;
    height:30px;
    width: 750px;
    border-bottom:1px solid #666;   
}

/* single tab */
ul.css-tabs li {  
    float:left;  
    padding:0; 
    list-style-type:none;   
}

/* link inside the tab. uses a background image */
ul.css-tabs a { 
    float:left;
    font-size:13px;
    display:block;
    padding:5px 30px;   
    text-decoration:none;
    border:1px solid #666;  
    border-bottom:0px;
    height:18px;
    color:#777;
    margin-right:2px;
    position:relative;
    top:1px;    
    outline:0;
    -moz-border-radius:4px 4px 0 0; 
    background: #bbbbbb url(nav.jpg) repeat-x;
    color: #FFF;
    text-align: left;
    white-space:nowrap;
}

ul.css-tabs a:hover {
    background-color:#F7F7F7;
    color:#333;
}

/* selected tab */
ul.css-tabs a.current {
    background-color:#ddd;
    border-bottom:1px solid #ddd;   
    color:#000; 
    cursor:default;
}


/* tab pane */
.css-panes div {
    display:none;
    border:1px solid #666;
    border-width:0 1px 1px 1px;
    min-height:800px;
    padding:15px 20px;
    background-color:#ddd;
    margin-left: 10px;
    width: 710px;
    position: absolute; 
    left: -1000px;  
}

解决方案

Thanks for the sample page!!! The first bug I see is in your CSS.

/* tab pane */
.css-panes div {
  display: none;
  ...
}

The snippet above is being used to hide the css pages that aren't being loaded, but it's also reaching down and hiding any div that is under an element with a class .css-panes. In this case, display: none; is getting set on the map_canvas div. This selectors other elements like the sizing and coloring info is also messing up all the divs the Google Maps API draws. You should probably do something a bit less aggressive and perhaps add a pane class to each pane div and select directly on that.

After cleaning up your stylesheet a bit I can manually load a map by running the initialize() function in a JavaScript console. It looks like your bind / event trigger code isn't firing as intended. I'd add a simple console.log("Foo"); or even an alert("Test"); in place of the initialize method call to help debug the tabshow event. (I haven't had any luck getting it to work, nor am I a jQuery tab expert)
