谷歌地图api v3 infowindow + flot [英] google maps api v3 infowindow + flot
问题描述
我正在尝试在infowindow
中绘制图形,但是flot没有执行-并且没有引发任何错误.我在flot论坛上读到,经常有人在做这样的事情时遇到麻烦,因为占位符元素必须可见(在这里可能是红色的提示).
I'm trying to draw a graph inside an infowindow
, but flot is not executing—and is not throwing any errors. I read in the flot forum that often people have trouble with doing something like this because the placeholder element must be visible (that might be a red-herring here tho).
我能够获得以下内容,以在不同的元素中适当地生成图形:
I'm able to get the following to produce the graph appropriately in a different element:
$.plot(
$("#placeholder"),
[ f_data[loc] ],
{
grid: { hoverable: true, clickable: true },
series: {
bars: { show: true },
clickable:true,
color:'#3FA9F5',
shadowSize: 0
},//series
xaxis: {
tickDecimals:0,
tickSize:1
}//xaxis
}
);//$.plot
但是当我将上述内容放入google.maps.event.addListener()
或从中引用时,它什么也没做(甚至不添加<canvas>
元素).
But when I put the above into, or referenced from, the google.maps.event.addListener()
, it does nothing (not even add the <canvas>
elements).
我确保将其放在infowindow.open(map,marker);
之后,以便使我认为占位符元素可见.我还确保#placeholder
具有实体/定义的尺寸.
I made sure to put it after infowindow.open(map,marker);
, so that makes me think the placeholder element is visible. I also made sure #placeholder
has substance/defined dimensions.
P.S.我尝试了Mike Williamson报告的最终解决方案,该解决方案是 Google Maps V3:通过AJAX加载信息窗口内容,但是没有用要么.
P.S. I tried what Mike Williamson reported as his eventual solution to Google Maps V3: Loading infowindow content via AJAX, but that didn't work either.
编辑
在信息窗口外进行浮动处理的示例: index2.html
flot无法在信息窗口(addListener'domready')内部运行的示例: index3.html
flot无法在信息窗口(setTimeout)内运行的示例: index4.html
EDIT
Example of flot working outside of infowindow: index2.html
Example of flot not working inside of infowindow (addListener 'domready'): index3.html
Example of flot not working inside of infowindow (setTimeout): index4.html
推荐答案
问题是内容div尚未附加到域(因此$(#placeholer")找不到它).您需要先等待infowindow domready事件触发,然后再运行代码以绘制图形,如下所示:
The issue is that the content div has not been attached to the domain yet (so $("#placeholer") can't find it). You need to wait for the infowindow domready event to fire before running your code to plot the graph, something like this:
更新:以下代码在本地副本上对我有用(我确实修改了CSS,但我认为这不是必需的.)
UPDATE: The code below works for me on a local copy (I did modify the css, but I don't think that was required).
google.maps.event.addListener(marker, 'click', (function(marker, locale, s, flot_data) {
return function() {
var fname = 'http://clients.frende.me/incognito/images/'+date+'_'+locale.toLowerCase().replace(/\s/g,'')+'.svg';
infowindow.setContent('<div id="gMaps_infowindow"><h3>'+locale+' ('+hour+':00): $'+s.total+'</h3><div id="flotIW" style="height:200px; width:350px;" name="'+locale+'"></div></div>');
google.maps.event.addListener(infowindow, 'domready', function() {(function(f_data,loc) {
$.plot(
$("#flotIW"),
[ f_data[loc] ],
{
grid: { hoverable: true, clickable: true },
series: {
bars: { show: true },
clickable:true,
color:'#3FA9F5',
shadowSize: 0
},//series
xaxis: {
tickDecimals:0,
tickSize:1
}//xaxis
}
);//$.plot
})(flot_data,locale)});
infowindow.open(map, marker);
//open_popUp(flot_data,locale);
//open_drawGraph(locale);
}//return
})(marker, locale, s, flot_data));//google.maps.event.addListener
(另一种选择是直接创建域节点,使用该域节点渲染图形,然后将其传递给setContent调用(将使用字符串或DOM节点).
(another option is to create the domain node directly, use that to render your graph, and pass that into the setContent call (which will take either a string or a DOM node).
