js中调整窗口大小时调整svg大小

本文介绍了在d3.js中调整窗口大小时调整svg大小的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

我用d3.js绘制散点图。在此问题的帮助下:



我使用这个答案:

  var w = window,
d = document,
e = d.documentElement,
g = d.getElementsByTagName('body')[0],
x = w.innerWidth || e.clientWidth || g.clientWidth,
y = w.innerHeight || e.clientHeight || g.clientHeight;

所以我可以像这样将我的剧情贴合到用户的窗口:

  var svg = d3.select(body)append(svg)
.attr(width,x)
.attr(height,y)
.append(g);

现在我想,当用户调整窗口大小时, / p>

PS:我的代码中没有使用jQuery。

解决方案

寻找响应SVG,它是相当简单的SVG响应,你不必再担心大小了。



以下是我的操作方式:

  d3.select div#chartId)
.append(div)
.classed(svg-container,true)//容器类使其响应
.append(svg )
//响应SVG需要这两个属性,没有宽度和高度attr
.attr(preserveAspectRatio,xMinYMin meet)
.attr(viewBox,0 0 600 400)
//类响应
.classed(svg-content-responsive,true);

CSS代码:

  .svg-container {
display:inline-block;
position:relative;
width:100%;
padding-bottom:100%; / * aspect ratio * /
vertical-align:top;
overflow:hidden;
}
.svg-content-responsive {
display:inline-block;
position:absolute;
top:10px;
left:0;
}

I'm drawing a scatterplot with d3.js. With the help of this question :
how to get web page size, browser window size, screen size in a cross-browser way?

I'm using this answer :

var w = window,
    d = document,
    e = d.documentElement,
    g = d.getElementsByTagName('body')[0],
    x = w.innerWidth || e.clientWidth || g.clientWidth,
    y = w.innerHeight|| e.clientHeight|| g.clientHeight;

So I'm able to fit my plot to the user's window like this :

var svg = d3.select("body").append("svg")
        .attr("width", x)
        .attr("height", y)
        .append("g");

Now I'd like that something takes care of resizing the plot when the user resize the window.

PS : I'm not using jQuery in my code.

解决方案

Look for 'responsive SVG' it is pretty simple to make a SVG responsive and you don't have to worry about sizes any more.

Here is how I did it:

d3.select("div#chartId")
   .append("div")
   .classed("svg-container", true) //container class to make it responsive
   .append("svg")
   //responsive SVG needs these 2 attributes and no width and height attr
   .attr("preserveAspectRatio", "xMinYMin meet")
   .attr("viewBox", "0 0 600 400")
   //class to make it responsive
   .classed("svg-content-responsive", true);

The CSS code:

.svg-container {
    display: inline-block;
    position: relative;
    width: 100%;
    padding-bottom: 100%; /* aspect ratio */
    vertical-align: top;
    overflow: hidden;
}
.svg-content-responsive {
    display: inline-block;
    position: absolute;
    top: 10px;
    left: 0;
}
