我在我的页面上有一个我想优化的深入贴图。 现在我正在加载每个“深入”地图,即使它没有被点击。优化JavaScript DrillDown代码
Here是一个示例,显示如果状态被点击,数据如何加载。我想实现这一点。
但是,这是我的代码,正如你所看到的,即使地图没有被点击,我也会加载所有向下钻取的jsons。在我的例子中,我只有2个向下钻取选项,但在我现实生活中的问题中,我有15个,所以它确实减慢了一切。
所以这是我的代码:
从generate_json_region_1.php[{"drilldown":"a","name":"region 1","value":"1","path":""},{"drilldown":"b","name":"region 2","value":"2","path":""}]
JSON:
// get main map
$.getJSON('json/generate_json_main_map.php', function(data) {
// get region 1 map
$.getJSON('json/generate_json_region_1.php', function(first_region) {
// get region 2 map
$.getJSON('json/generate_json_region_2.php', function(second_region) {
// Initiate the chart
$('#interactive').highcharts('Map', {
title: {
text: ''
},
colorAxis: {
min: 1,
max: 10,
minColor: '#8cbdee',
maxColor: '#1162B3',
type: 'logarithmic'
},
series: [{
data: data,
"type": 'map',
name: st_ponudb,
animation: {
duration: 1000
},
states: {
//highlight barva
hover: {
color: '#dd4814'
}
}
}],
drilldown: {
drillUpButton: {
relativeTo: 'plotBox',
position: {
x: 0,
y: 0
},
theme: {
fill: 'white',
'stroke-width': 0,
stroke: 'white',
r: 0,
states: {
hover: {
fill: 'white'
},
select: {
stroke: 'white',
fill: 'white'
}
}
}
},
series: [{
id: 'a',
name: 'First',
joinBy: ['hc-key', 'code'],
type: 'map',
data: first_region,
point: {
events: {
click: function() {
var key = this.key;
location.href = key;
}
}
}
}, {
id: 'b',
name: 'Second',
joinBy: ['hc-key', 'code'],
type: 'map',
data: second_region,
point: {
events: {
click: function() {
var key = this.key;
location.href = key;
}
}
}
}]
}
});
});
});
});
从generate_json_main_map.php JSON
[{"name":"Place 1","key":"place.php?id=1","value":"1","path":""},{"name":"Place 2","key":"place.php?id=2","value":"2","path":""}]
这是我试图让阿贾克斯调用并行加载,但地图不加载,我只得到coloraxis。
$(function() {
$.when($.getJSON('json/generate_json_main_map.php'), $.getJSON('json/generate_json_region_1.php'), $.getJSON('json/generate_json_region_2.php')).done(function(data,first_region,second_region){
$('#interactive').highcharts('Map', {
title: {
text: ''
},
colorAxis: {
min: 1,
max: 10,
minColor: '#8cbdee',
maxColor: '#1162B3',
type: 'logarithmic'
},
series: [{
data: data,
"type": 'map',
name: st_ponudb,
animation: {
duration: 1000
},
states: {
hover: {
color: '#dd4814'
}
}
}],
drilldown: {
drillUpButton: {
relativeTo: 'plotBox',
position: {
x: 0,
y: 0
},
theme: {
fill: 'white',
'stroke-width': 0,
stroke: 'white',
r: 0,
states: {
hover: {
fill: 'white'
},
select: {
stroke: 'white',
fill: 'white'
}
}
}
},
series: [{
id: 'a',
name: 'First',
joinBy: ['hc-key', 'code'],
type: 'map',
data: first_region,
point: {
events: {
click: function() {
var key = this.key;
location.href = key;
}
}
}
}, {
id: 'b',
name: 'Second',
joinBy: ['hc-key', 'code'],
type: 'map',
data: second_region,
point: {
events: {
click: function() {
var key = this.key;
location.href = key;
}
}
}
}]
}
});
});
});
我可以看到,jsons被加载,并没有显示由萤火虫JS错误。
任何人,任何建议? – DJack
没有完全花时间来理解这段代码,但是你不能点击某个区域,发送该区域的“id”并只获得该特定区域的向下钻取数据? –
您可以尝试并行处理这三个请求,这可能会有所帮助。 – Whymarrh
