将 jquery 滑块与processing.js 结合使用
我正在使用 XML 中的值进行处理,创建一个简单的条形图。该数据是9个山脉28年的冰川质量平衡。我正在尝试用它来实现一个jquery滑块(我可以将它发布到processing.js中......我只是不知道从那里去哪里)。为了能够看到我的所有数据,现在我只是一次性显示所有 28 年的数据。
使用 jquery 滑块,我希望能够在 1980 年到 2007 年之间滑动,并仅显示其中一年的条形图。我是否需要大幅更改处理代码才能使其正常工作?我发现的很多例子都没有广泛使用数组,而且处理草图也更简单。 (我对此很陌生,所以请忍受我的业余问题)。任何提示/指示表示赞赏。
float[] yearA = new float[28];
String[] mountA = new String[9];
float[] massA = new float[9];
float[] recth = new float[9];
float rectw;
int rectx = 10;
int recty = 20;
float rectht;
void setup()
{
size(500,800);
}
void draw()
{
XMLElement years = new XMLElement(this, "glacier2.xml");
println(years.getChildCount());
int nResults = years.getChildCount();
int x=40;
int y=40;
background(255);
fill(0);
for(int j=0; j<28; j++) {
XMLElement yearN = years.getChild(j);
String yearn = yearN.getAttribute("id");
float yearnf = float(yearn);
yearA[j] = yearnf;
println(yearA[j]);
for(int i=0; i<9; i++) {
XMLElement mountains = yearN.getChild(i);
String mountain = mountains.getAttribute("id");
String massbalance = mountains.getAttribute("massbalance");
float massf = float(massbalance);
mountA[i] = mountain;
massA[i] = massf;
rectht = map(massf, -4260, 3700, 10, 750);
recth[i]=rectht;
rectw = floor(width/10);
rect(rectx, recty, rectw, recth[i]);
rectx+=(rectw+10);
text(massf, rectx, recty+rectht);
println(massf);
}
rectx=10;
}
}
I am creating a simple bar graph in processing using values from an XML. The data is glacier mass balance for 9 mountain ranges for 28 years. I am trying to implement a jquery slider with this (I can post it into processing.js...I just don't know where to go from there). To be able to see all my data, right now I am just showing all 28 years at once.
With a jquery slider I want to be able to slide between the years 1980 to 2007 and show the bars with only one of those years. Do I need to change my processing code drastically to make this work? A lot of the examples I found weren't using arrays extensively and the processing sketches were simpler. (I am pretty new at this so please bear with my amateur question). Any hints/pointers are appreciated.
float[] yearA = new float[28];
String[] mountA = new String[9];
float[] massA = new float[9];
float[] recth = new float[9];
float rectw;
int rectx = 10;
int recty = 20;
float rectht;
void setup()
{
size(500,800);
}
void draw()
{
XMLElement years = new XMLElement(this, "glacier2.xml");
println(years.getChildCount());
int nResults = years.getChildCount();
int x=40;
int y=40;
background(255);
fill(0);
for(int j=0; j<28; j++) {
XMLElement yearN = years.getChild(j);
String yearn = yearN.getAttribute("id");
float yearnf = float(yearn);
yearA[j] = yearnf;
println(yearA[j]);
for(int i=0; i<9; i++) {
XMLElement mountains = yearN.getChild(i);
String mountain = mountains.getAttribute("id");
String massbalance = mountains.getAttribute("massbalance");
float massf = float(massbalance);
mountA[i] = mountain;
massA[i] = massf;
rectht = map(massf, -4260, 3700, 10, 750);
recth[i]=rectht;
rectw = floor(width/10);
rect(rectx, recty, rectw, recth[i]);
rectx+=(rectw+10);
text(massf, rectx, recty+rectht);
println(massf);
}
rectx=10;
}
}

您不需要做很多工作,但需要确保做得正确 - 您需要在 javascript 方面捕获草图实例(请参阅 http://processingjs.org/reference/articles/PomaxGuide#jstosketch 了解详细的操作方法。别担心,这是一个小部分)并且每当您移动 jQuery 滑块时,您想要调用一些
在处理方面的东西,您将需要定义 updateYear 方法:
所以这不是一个很大的工作,祝你好运!
You won't need to do a lot of work, but you will need to make sure to do it right - you'll want to catch the sketch instance on the javascript side of things (see http://processingjs.org/reference/articles/PomaxGuide#jstosketch for a nicely detailed how. Don't worry, it's a small section) and whenever you move your jQuery slider, you want to call some
On the Processing side of things, you'll want that updateYear method defined:
So it's not a great deal of work, good luck!
这是页面底部带有代码的示例,可能会有所帮助。但是,您需要 WebGL 浏览器来呈现页面。

Here's an example with code at the bottom of the page, which may help. However, you'll need a WebGL browser to render the page.
