My script draws lines on the screen at a stroke-width of 3. The size of lines are ideal (visually) but they aren't very easy to click.
我的脚本在屏幕上以3的笔划宽度绘制线条。线条的大小是理想的(视觉上),但它们不是很容易点击。
As a rough example:
作为一个粗略的例子:
<html>
<head>
<script>
function selectStrand(evt) {
current_id = evt.target.getAttributeNS(null, "id");
document.getElementById('main').innerHTML = current_id;
}
</script>
</head>
<body>
Selected line: <span id="main"></span>

Is there a simple way to increase the area around each of the lines to make them easier to click?
有没有一种简单的方法来增加每条线周围的区域,使它们更容易点击?

For each line, try drawing a transparent line on top of it with a larger stroke width, and set the onclick on that.
对于每一行,尝试在其上方绘制一条具有较大笔划宽度的透明线,并在其上设置onclick。

A variation on the above answer. For a cool selection effect group each thin line and transparent line combo in a group with the thin line on top. Set the onclick to the group and then animate the transparency of the thick line in your onclick.
上述答案的变体。对于较酷的选择效果组,每条细线和透明线组合在一起,顶部有细线。将onclick设置为组,然后在onclick中为粗线的透明度设置动画。
