Abd*_*eed 9 javascript svg ios d3.js
我正在使用d3 v4渲染SVG图形.我在几个元素上使用了clipPath<path>.我在rect元素上有平移行为,而clipPath正在帮助隐藏一些路径元素.在android中平移时.clipPath可以根据需要运行,但是在iOS中进行平移时,绘图会变得很时髦.见下文:
之前
我用以下代码实现了SVG剪辑:
this.line = d3.line()
.curve(d3.curveMonotoneX)
.x((d) => this.xScale(this.getDate(d)))
.y((d) => this.yScale(d.kWh));
this.area = d3.area()
.curve(d3.curveMonotoneX)
.x((d) => {
return this.xScale(this.getDate(d))
})
.y0(this.height)
.y1((d) => this.yScale(d.kWh));
// Definition for clipPath
this.svg.append("defs").append("clipPath")
.attr("id", "clip")
.append("rect")
.attr("width", this.width)
.attr('transform', 'translate(0,-20)')
.attr("height", this.height + 20);
// clipPath added to area
var areaPath = this.focus.append("path")
.datum(this.data)
.attr("class", "area")
.attr('height', this.height)
.attr('fill-opacity', .2)
.attr('clip-path', 'url(#clip)')
.attr("d", this.area)
.attr("transform", "translate(0," + 80 + ")")
.style("fill", "url(#gradient)");
// clipPath added to the line
var linePath = this.focus.append('path')
.datum(this.data)
.attr('class', 'line')
.attr('fill', 'none')
.attr('clip-path', 'url(#clip)')
.attr('stroke', '#31B5BB')
.attr('stroke-width', '2px')
.attr("transform", "translate(0," + 80 + ")")
.attr('d', this.line);

他是变焦时缩放的摘录.
private zoomed = () => {
if (this.isMinZooming) return;
let diff,
domain,
minBuffer,
maxBuffer,
t;
t = d3.event.transform;
// loose mobile events
if (isNaN(t.k)) return;
this.xScale.domain(t.rescaleX(this.x2Scale).domain());
diff = this.daydiff(this.xScale.domain()[0], this.xScale.domain()[1]);
// Redraw Axis
this.xAxis = d3.axisBottom(this.xScale).tickSize(0).tickFormat(d3.timeFormat('%b'));
this.focus.select(".axis--x").call(this.xAxis);
// Redraw Paths. This is where the redraw function gets messy in the iOS webview.
this.focus.select(".area").attr("d", this.area);
this.focus.select('.line').attr('d', this.line);
...

使用clipPath时有没有人遇到过同样的问题?
我想通了这个问题。这是一个如此愚蠢的错误。我在 css 文件中的某处定义:
.area{
clip-path: url(#clip);
}

在所有浏览器中,这都适用于<rect>和<path>,但对于 ,iOS webview它会呈现上述显示错误。
我不是在一个单独的文件中定义它 ,而是为我想要应用它的CSS所有内容内联定义它:SVG Object
var areaPath = this.focus.append("path")
...
.attr('clip-path', 'url(#clip)') //defining it inline

这个错误让我发疯,但我很高兴我找到了解决方案。
