我想在 jQuery 移动页面中实现一些可视化统计信息。如果我嵌入以下代码段,它将向我显示与从单独的 *.svg 文件中嵌入它相同的结果。
<svg xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" height="115" width="100%">
<rect x="0%" y="0" fill="#8cc63f" width="19.2%" height="100" />
<text x="10%" y="115" font-family="helvetica, sans-serif" font-size="10" style="text-anchor:middle;">A</text>
<text x="10%" y="15" font-family="helvetica, sans-serif" font-size="10" style="text-anchor:middle;">100</text>
<rect x="20.2%" y="50" fill="#8cc63f" width="19.2%" height="50" />
<text x="30.2%" y="115" font-family="helvetica, sans-serif" font-size="10" style="text-anchor:middle;">B</text>
<text x="30.2%" y="65" font-family="helvetica, sans-serif" font-size="10" style="text-anchor:middle;">50</text>
<rect x="40.4%" y="90" fill="#8cc63f" width="19.2%" height="10" />
<text x="50.4%" y="115" font-family="helvetica, sans-serif" font-size="10" style="text-anchor:middle;">C</text>
<text x="50.4%" y="85" font-family="helvetica, sans-serif" font-size="10" style="text-anchor:middle;">10</text>
<rect x="60.6%" y="78" fill="#8cc63f" width="19.2%" height="22" />
<text x="70.6%" y="115" font-family="helvetica, sans-serif" font-size="10" style="text-anchor:middle;">D</text>
<text x="70.6%" y="73" font-family="helvetica, sans-serif" font-size="10" style="text-anchor:middle;">22</text>
<rect x="80.8%" y="40" fill="#8cc63f" width="19.2%" height="60" />
<text x="90.8%" y="115" font-family="helvetica, sans-serif" font-size="10" style="text-anchor:middle;">E</text>
<text x="90.8%" y="55" font-family="helvetica, sans-serif" font-size="10" style="text-anchor:middle;">60</text>
现在因为每个站点的这些统计数据显然会发生变化,所以我使用 JavaScript 生成类似于上面的代码。HTML-Source-Code 看起来相同,但 SVG 不会显示。相反,它看起来像这样:
A 100 B 50 C 10 D 22 E60
所以真的只是一行文字
我的 js (backbone_js) 看起来像这样:
/* Rendert den Publikumsjoker */
_.extend(KM.Views, {
"StatsPubJoker" : Backbone.View.extend({
tagName : 'svg:svg',
attributes:{
'type':'image/svg+xml',
'xmlns':"http://www.w3.org/2000/svg",
//'xmlns:svg':"http://www.w3.org/2000/svg",
'xmlns:xlink':"http://www.w3.org/1999/xlink",
'version':'1.1',
// 'baseProfile':'tiny',
height:'115',
width:'100%'
},
initialize : function() {
_.bindAll(this, 'render');
_.bindAll(this, 'renderSingleBar');
// Fragenmodel hintelegen
this.model = this.options.model;
// Anzahl an Antwortmöglichkeiten
var countAnswerOptions = _.keys(this.model.get('stats').pubJoker.prozDistribution).length;
// Optionen zum Plotten hinterlegen
this.plotOptions = {
// Summe aller gemachten Kreuze hinterlegen (=n)
n : this.model.get('stats').pubJoker.sumup,
// Anzahl unterschiedlicher Antwortmöglichkeiten zwischenspeichern
N : countAnswerOptions,
// Breiten festlegen (in Prozent)
barWidth : (99 / countAnswerOptions), // + '%',
spacerWidth : 1 / (countAnswerOptions-1), // + '%',
textOffset: 99 / countAnswerOptions * 2
};
console.log(this.plotOptions);
// counter für Balken
this.barCounter = 0;
// Das Template laden
this.template = _.template($('#stats-pubjoker-singleitem').html());
},
render : function() {
if(this.plotOptions.n == undefined || this.plotOptions.n == 0 || this.plotOptions.n == 0) return this;
console.log(this.model.get('stats').pubJoker.prozDistribution);
_.each(this.model.get('stats').pubJoker.prozDistribution, this.renderSingleBar);
return this;
},
renderSingleBar: function(singleitem,letterkey){
var singleBarOptions = {};
singleBarOptions.xposBar = (this.plotOptions.barWidth + this.plotOptions.spacerWidth) * this.barCounter;
singleBarOptions.xposText = this.plotOptions.textOffset + singleBarOptions.xposBar;
singleBarOptions.yposLetter = 115;
singleBarOptions.yposBar = parseFloat(singleitem);
singleBarOptions.letter = letterkey;
singleBarOptions.value = singleitem;
singleBarOptions.yposTextNumber = singleBarOptions.yposBar < 25 ? singleBarOptions.yposBar + -15 : singleBarOptions.yposBar +5;
console.log(singleBarOptions);
this.$el.append(this.template(_.extend(singleBarOptions, this.plotOptions)));
this.barCounter++;
return false;
}
})
});
我错过了什么吗?谢谢您的帮助!
